Iowa — Sales & Use Tax

Iowa imposes a 6 percent sales tax on the sales price of all sales of tangible personal property and certain enumerated services. The complementary use tax applies at the same rate to the use of tangible personal property and services within Iowa when sales tax has not been collected. Unlike tangible personal property, which is subject to sales tax unless specifically exempted, services are taxable only when specified by Iowa law. Iowa Code § 423.2(6) lists dozens of taxable services, including vehicle repair, alteration and garment repair, barber and beauty services, campgrounds, household appliance repair, and pay television. The Iowa Department of Revenue maintains a current list of taxable services.

Remote sellers must collect Iowa sales tax if they have $100,000 or more in gross revenue from Iowa sales in the current or immediately preceding calendar year. The threshold includes all Iowa sales revenue—taxable, exempt, wholesale, and marketplace-facilitated transactions. Iowa eliminated its 200-transaction threshold effective July 1, 2019, leaving only the revenue threshold. A remote seller meeting the threshold must register and begin collecting tax on the first day of the next calendar month that starts at least 30 days after exceeding the threshold.

Iowa imposes a state sales tax at a rate of 6 percent on sales of tangible personal property and on the enumerated services listed in Iowa Code § 423.2(6). The complementary use tax applies at the same 6 percent rate under Iowa Code § 423.5. Tangible personal property is taxable unless specifically exempted; services are taxable only when enumerated by statute.

Iowa Code § 423.2, subsection 12, provides: "The sales tax rate of six percent is reduced to five percent on January 1, 2051." This scheduled reduction is codified in the statute and has not been repealed or superseded by subsequent legislation as of June 2026.

The state rate does not include local option sales taxes, which most Iowa jurisdictions impose at an additional 1 percent under Iowa Code chapter 423B. The local option tax applies to the same tax base as the state sales tax.

Marketplace facilitators making or facilitating sales to Iowa customers must obtain, retain, and provide exemption certificates (including for resale) when an exemption is claimed by a marketplace buyer. Under Iowa Admin. Code r. 701-207.13(3), a purchaser may furnish an exemption certificate naming the marketplace facilitator as the seller. The certificate may be used by the facilitator to support the exemption on any sale the facilitator makes or facilitates as required by Iowa Code chapter 423.

For exemptions, Iowa follows the Streamlined Sales and Use Tax Agreement (SSUTA) uniform certificate, and the Iowa exemption certificate (Form 31-014a) may be provided in paper or electronic form. The marketplace facilitator is responsible for obtaining the completed certificate from the buyer at the time of sale or within 90 days after the sale. If a valid exemption certificate is obtained within this window, the facilitator is relieved of liability for tax on that transaction—even if the certificate is obtained after the tax was charged initially and a refund is then issued. If the certificate is not obtained, the facilitator is generally liable for uncollected tax unless other evidence clearly supports the exemption.

The rules for accepting and retaining exemption certificates apply to both resale and other types of exemptions (e.g., sales to exempt organizations or sales of exempt property). Marketplace facilitators are subject to the same documentary and retention requirements as direct sellers under Iowa Admin. Code r. 701-209.1.

Summary of requirements:

• The facilitator must obtain a completed exemption certificate from the buyer (naming the facilitator as the seller) at or within 90 days of sale.
• The facilitator must retain the exemption certificate in its books and records as long as required by DOR regulations.
• Valid certificates provided within the 90-day grace period relieve the facilitator of liability; certificates provided after 90 days may be accepted at DOR’s discretion if other evidence supports the exemption, but safe-harbor protection is not guaranteed.
• These requirements apply to sales for resale and other exemption categories claimed by Iowa buyers on marketplace sales.

Iowa assigns sales and use tax filing frequency based on annual tax liability. Effective July 1, 2022, Iowa eliminated semimonthly and quarterly filing options for sales and use tax, leaving only two filing frequencies: annual and monthly.

Annual filing

Businesses collecting less than $1,200 in sales and use tax per year file annual returns due January 31 of the following year. Annual filers are not required to file electronically, though they may do so.

Monthly filing

Businesses collecting $1,200 or more in sales and use tax per year file monthly returns due the last day of the month following the reporting period. Monthly filers must file electronically through GovConnectIowa. For example, the return and payment for tax collected in July is due August 31.

Seasonal filing

Seasonal businesses operating four months or fewer per year may file monthly returns only for months of operation if they meet the $1,200 annual threshold. The months need not be consecutive. To obtain seasonal filing status, a business must cancel its current permit and register for a new permit; businesses cannot switch to seasonal status through the Business Change Form.

Mandatory monthly filing for certain excise taxes

Certain excise taxes require monthly filing regardless of tax liability amount. These include hotel and motel tax, automobile rental tax, and construction equipment tax. Water service excise tax remains on a separate permit and return and may be filed either monthly or annually.

Elimination of semimonthly filing effective July 2022

On June 17, 2022, Governor Reynolds signed Senate File 2367, which eliminated semimonthly filing and deposit-payment requirements for sales and use tax effective July 1, 2022. Before this change, businesses with more than $60,000 in annual sales and use tax liability were required to make semimonthly deposit payments (twice per month) and file quarterly returns. Under the new law, all sales and use tax permit holders file either monthly or annually and remit actual taxes collected at the time of filing.

The elimination of semimonthly filing applies only to sales and use tax. Iowa withholding tax (a separate tax type) still requires semimonthly deposit payments for employers with more than $120,000 in annual withholding tax liability. Practitioners should not confuse the two regimes—sales tax has only monthly and annual filing; withholding tax retains quarterly, monthly, and semimonthly schedules.

Filing-frequency changes

The Iowa Department of Revenue may change a taxpayer's filing frequency if tax collections increase or decrease substantially over multiple filing periods. Retailers may request a filing frequency change by logging into GovConnectIowa and submitting a Filing Frequency Change request or by submitting an Iowa Business Tax Change Form (92-033). The change is usually effective at the beginning of the next tax period. Taxpayers under the annual filing threshold of $1,200 may request to file and pay monthly.

Due-date adjustments

If the due date falls on a Saturday, Sunday, or holiday as defined in Iowa Code § 421.9A, the due date is the following day that is not a Saturday, Sunday, or holiday. If filing on paper (permitted only for annual filers), the postmark date is accepted as the filing date.

Iowa authorizes counties and cities to impose a local option sales and services tax at a rate of one percent on transactions subject to the state sales tax. The local option tax must be approved by voters in the jurisdiction and may be imposed in a city, in the unincorporated area of a county, or county-wide. Within a county, some cities may impose the tax while others do not. A jurisdiction may enact or repeal the local option tax on January 1 or July 1. The rate is fixed at one percent by Iowa Code § 423B.1(3)—local jurisdictions cannot vary the rate.

Tax Base and Sourcing

The local option sales tax applies to the same tax base as the state sales tax. All sales subject to state sales tax under Iowa Code chapter 423 are subject to local option sales tax. Remote sellers and marketplace facilitators that meet Iowa's economic nexus threshold under Iowa Code § 423.14A must collect local option sales tax on taxable sales sourced to Iowa, the same as retailers with a physical presence in Iowa. This obligation became effective July 1, 2019.

Iowa does not impose a local option use tax—that is, purchasers who self-assess Iowa use tax on out-of-state purchases do not separately calculate or remit local option tax. However, the absence of a local option use tax does not relieve remote sellers with nexus from collecting local option sales tax. Once a remote seller or marketplace facilitator meets the $100,000 economic nexus threshold, the seller must collect both state sales tax and applicable local option sales tax on all taxable sales sourced to locations within Iowa jurisdictions that impose the local option tax.

The local option tax applies to transactions sourced under Iowa's general sourcing rules (Iowa Code § 423.15 and Iowa Admin. Code r. 701-205) to a location within the jurisdiction imposing the tax. Retailers use the same destination-based sourcing rules that apply to state sales tax to determine whether a sale is subject to local option tax and in which jurisdiction the tax applies.

The local option tax cannot be imposed on any transaction not subject to state sales tax. Specific exemptions from local option tax include motor fuel and special fuel consumed for highway use (if fuel tax is paid and no refund has been or will be allowed); sales by the Iowa Department of Transportation; and sales of natural gas or electricity in jurisdictions where those sales are subject to a franchise fee or user fee during the period the fee is imposed.

Collection and Administration

Retailers collect local option sales tax using the same state sales tax permit required under Iowa Code § 423.36. No separate local option tax permit is required. Retailers remit local option tax to the Iowa Department of Revenue along with state sales tax; no payment is made directly to local jurisdictions. Returns break down local option taxable sales and tax by county. The amount of local option tax collected is not included when determining a retailer's filing frequency—only state sales tax liability determines whether a retailer files monthly or annually.

When a retailer should have collected both state sales tax and local option sales tax but failed to do so, the retailer remains liable for the uncollected local option tax even if the purchaser subsequently remits use tax to Iowa. Because there is no local option use tax, the retailer's failure to collect cannot be cured by the purchaser's use tax payment.

Recent Jurisdictional Changes: Effective 2026

Several new Iowa jurisdictions will newly impose or discontinue local option sales tax in 2026. Per the Iowa Department of Revenue's June 2026 publication, Coralville, Iowa City, North Liberty, Oxford, and Shueyville will begin imposing the one percent local option sales tax effective July 1, 2026. Conway discontinued the tax effective April 1, 2026. For a full, current jurisdictional list, see the DOR's jurisdiction update page linked below.

Effective Dates

Local option taxes may be imposed only on January 1 or July 1, and the imposition date must be at least 90 days after the date of the election approving the tax. The imposition date must be uniform in all areas of the county voting on the tax at the same election. Jurisdictions may also submit a ballot measure providing for automatic repeal of the local option tax on a specific date (which must fall on January 1 or July 1) without requiring a subsequent election.

Iowa imposes distinct penalties for late filing and late payment of sales and use tax under Iowa Code § 421.27, and both may apply if a taxpayer files late and pays late. Interest accrues separately on all unpaid tax under Iowa Code § 421.7.

Failure to timely file penalty

A 5 percent penalty is assessed on the unpaid tax when a sales and use tax return is not filed by the due date. This penalty applies to the amount of tax remaining unpaid as of the due date, regardless of whether the taxpayer later pays the tax. Once imposed, the failure-to-file penalty is assessed on all subsequent amounts found by the taxpayer or the Department to be due for the same tax period.

Failure to timely pay penalty

A separate 5 percent penalty is assessed on unpaid tax when the taxpayer files a return by the due date but fails to pay at least 90 percent of the tax due by that date. Iowa law provides a safe harbor: if the taxpayer pays at least 90 percent of the correct tax by the original due date, no late-payment penalty is assessed on the remaining balance, even if the return itself is filed late or the final balance is paid late. The 90 percent test is calculated on the correct amount of tax due, not the amount the taxpayer initially reported.

Both penalties may apply

If a taxpayer both fails to file a return by the due date and fails to pay at least 90 percent of the tax by the due date, Iowa assesses both the failure-to-file penalty and the failure-to-pay penalty. The two penalties are independent and cumulative under Iowa Code § 421.27(1) and (2). A taxpayer in this scenario incurs a total penalty of 10 percent of the unpaid tax—5 percent for late filing and 5 percent for late payment.

Audit penalty

If the Iowa Department of Revenue discovers an underpayment during an audit or examination, a 5 percent penalty is added to the additional tax found to be due. This audit penalty applies in addition to any late-filing or late-payment penalty already assessed.

Fraudulent return or willful failure to file

A 75 percent penalty is assessed on any unpaid tax or fraudulent claim when a taxpayer willfully fails to file a return or files a fraudulent return with the intent to evade tax. This penalty is not subject to waiver under any circumstance. Iowa Code § 421.27(7) and the Iowa Department of Revenue treat fraud penalties as non-waivable.

Interest

Interest is added to all unpaid tax from the original due date of the return until the tax, penalty, and interest are paid in full. Interest accrues at a rate set annually by the Director of Revenue under Iowa Code § 421.7. The rate is based on the average monthly prime rate during the preceding twelve-month period (October through September), rounded to the nearest whole percent, plus two percentage points. The monthly rate is the annual rate divided by twelve, rounded to the nearest one-tenth of a percentage point. Interest accrues each calendar month or fraction of a month—a partial month is treated as a full month for purposes of calculating interest. The interest rate may change each calendar year.

Interest is imposed in addition to any penalty. Even when a penalty is waived, interest continues to accrue on unpaid tax from the original due date.

Penalty waivers

Iowa Code § 421.27 and Iowa Administrative Code rule 701-10.7 permit the Department to waive late-filing and late-payment penalties under limited circumstances, including: (1) at least 90 percent of the tax due was paid by the due date; (2) for monthly or quarterly filers, one late return or one late payment within a three-year period (the taxpayer must then make timely filings and payments for three years before being eligible for another waiver under this provision); (3) death of the taxpayer, a member of the taxpayer's immediate family, or the person directly responsible for filing the return and paying the tax, when the death interfered with timely filing or payment; (4) serious long-term illness or hospitalization of the taxpayer, a family member, or the person responsible, when such illness interfered with timely filing or payment; or (5) other good-cause circumstances enumerated in the statute and administrative rules. The Department does not waive the 75 percent fraud penalty under any circumstance.

Penalty waiver requests are submitted on Iowa Department of Revenue Form 78-629 (Penalty Waiver Request) or, for eligible tax types, through GovConnectIowa.

Iowa imposes sales tax on "specified digital products" under Iowa Code § 423.2(10) and on "software as a service" as a separately enumerated taxable service under Iowa Code § 423.2(6)(bu). These provisions became effective January 1, 2019, when Iowa Senate File 2417 (2018 Iowa Acts) repealed the prior exemptions for electronically delivered products and online services.

Specified Digital Products Defined and Taxed

Iowa Code § 423.2(10)(a) imposes a 6 percent tax on the sales price of "specified digital products." Iowa Code § 423.1(55B)(a) defines "specified digital products" as "electronically transferred digital audio-visual works, digital audio works, digital books, or other digital products." The statute provides detailed sub-definitions:

• Digital audio-visual works (§ 423.1(55B)(b)(1)): a series of related images shown in succession and imparted with sounds, if any.
• Digital audio works (§ 423.1(55B)(b)(2)): works that result from the fixation of a series of musical, spoken, or other sounds, including ringtones. The statute defines "ringtones" as digitized sound files downloaded onto a device and used to alert the customer with respect to a communication.
• Digital books (§ 423.1(55B)(b)(3)): works that are generally recognized in the ordinary and usual sense as books.
• Other digital products (§ 423.1(55B)(b)(5)): greeting cards, images, video or electronic games or entertainment, news or information products, and computer software applications.

"Electronically transferred" is defined in § 423.1(55B)(b)(4) as "obtained or accessed by the purchaser by means other than tangible storage media, including but not limited to a specified digital product purchased through a computer software application, commonly referred to as an in-app purchase, or through another specified digital product, or through any other means."

The Iowa Department of Revenue's guidance publication, Taxation of Specified Digital Products, Software, and Related Services, states that before January 1, 2019, "all products delivered electronically were exempt from sales tax." Effective January 1, 2019, prewritten computer software became subject to sales tax "whether delivered or accessed in physical form (as tangible personal property) or electronically (as a specified digital product)." The guidance states that custom software sold in either physical or electronic form is now "taxed in the same manner as prewritten computer software," reversing the prior exemption for custom software.

Software as a Service (SaaS)

Iowa Code § 423.2(6)(bu) lists "software as a service" as a taxable service. The Iowa Department of Revenue guidance states that Iowa law "only imposes tax on 'software as a service' (SaaS)," distinguishing SaaS from other cloud-based services such as infrastructure as a service (IaaS), which the guidance says "are generally considered" IaaS and not subject to tax under the SaaS provision. The Department has separately determined that web-based storage is taxable under Iowa Code § 423.2(6)(bq) as "storage of tangible or electronic files, documents, or other records."

Iowa Code § 423.2(6)(bs) also lists as taxable "services arising from or related to installing, maintaining, servicing, repairing, operating, upgrading, or enhancing either specified digital products or software sold as tangible personal property."

Commercial Enterprise Exemption

Iowa Code § 423.3(104) exempts specified digital products, prewritten computer software, and the enumerated services listed in Iowa Code § 423.2(6)(bq) (storage), (br) (information services), (bs) (services related to installing, maintaining, or enhancing specified digital products or software), and (bu) (software as a service) when purchased by a commercial enterprise and used "exclusively" by that commercial enterprise.

Iowa Code § 423.3(104)(b)(1) defines "commercial enterprise" to include businesses, manufacturers, insurance companies, financial institutions, public utilities, professions, and occupations. The statute expressly excludes nonprofit organizations from the definition of "commercial enterprise," except that nonprofit insurance companies and nonprofit financial institutions are included.

Iowa Admin. Code r. 701-225.7(1) implements the exemption and defines "exclusively" to mean that "any use for noncommercial purposes occurs during the product's total use time, is so small as to make accounting for that use unreasonable or impractical." The regulation provides that "use in the ordinary course of a commercial enterprise's business constitutes exclusive use by a commercial enterprise."

To claim the exemption, the commercial enterprise must provide the vendor with Iowa Sales/Use/Excise Tax Exemption Certificate (Form 31-014A). The commercial enterprise exemption became effective January 1, 2019.

Effective Date and Repeal of Prior Exemptions

Iowa Senate File 2417 (2018 Iowa Acts) enacted the taxation of specified digital products and SaaS effective January 1, 2019. The legislation repealed Iowa Code §§ 423.3(65), (66), and (67), which had exempted access to online computer services, information services, and electronically delivered goods and services.

Iowa exempts numerous categories of tangible personal property and services from sales and use tax under Iowa Code § 423.3. The statute contains over 120 numbered subsections and is regularly amended. The exemptions below are those most frequently applied, with updates reflecting statutory changes through July 2026.

Food and Food Ingredients

Iowa Code § 423.3(57) exempts the sales price from all sales of "food and food ingredients" (not including alcoholic beverages, candy, dietary supplements, food sold through vending machines, prepared food, soft drinks, or tobacco). "Prepared food" and related definitions are set forth in detail in § 423.3(57).

Prescription Drugs and Medical Devices

Iowa Code § 423.3(60) exempts the sale or rental of prescription drugs, durable medical equipment, mobility-enhancing equipment, and prosthetic devices for human use. The exemption applies when dispensed to an "ultimate user." Definitions for "prescription drug" and "prosthetic device" are also provided in this section.

Sales for Resale

Iowa Code § 423.3(2) exempts sales for resale of tangible personal property or taxable services, or for resale of tangible personal property furnished in connection with the performance of taxable services. Exclusion rules on machinery and equipment in § 423.3(47) apply.

Manufacturing Machinery, Equipment, and Supplies

Iowa Code § 423.3(47) exempts machinery, equipment, computers, computer peripherals, replacement parts, supplies, and materials used or self-constructed when directly and primarily used in qualifying manufacturing, research and development, recycling, or processing, as defined in the statute. "Manufacturer" and related terms are defined at length in § 423.3(47)(d). Notably, the exemption for computers and computer peripherals for insurance companies, financial institutions, or commercial enterprises as formerly provided in § 423.3(47)(a)(4) has been repealed, effective January 1, 2024. This follows 2022 Iowa Acts, Senate File 2367.

Agricultural Production Inputs

Iowa Code § 423.3(3), (5), and (11) provide exemptions for: (1) agricultural breeding livestock and domesticated fowl; (2) agricultural limestone, pesticide, herbicide, food, medication, eligible farm tile and installation, among other specified items used directly in production agriculture; and (3) farm machinery and equipment (excluding vehicles subject to registration). Each exemption sets forth detailed definitions and eligibility criteria, and exclusions apply for some categories.

Honeybees – New Exemption Effective July 1, 2026

Effective July 1, 2026, Iowa Code § 423.3 is amended to exempt the sale of honeybees used in agricultural production. This newly enacted exemption should be considered when evaluating exempt sales after the effective date. Source: 2024 Iowa Acts, House File 2681; Iowa DOR Farmers Guide (updated June 2026).

Certain Government Purchases

Iowa Code § 423.3(31) exempts the sale of goods and services to or for use by tax-certifying or tax-levying bodies of the State of Iowa and its political subdivisions, as well as other specifically enumerated governmental entities.

Recent and Special Exemptions

• Web Search Portal Businesses: Iowa Code § 423.3(122) (added by 2024 legislation) exempts receipts from sales of electricity used by a web search portal business with a qualifying business data center resulting from new construction or additions completed on or after June 6, 2025. The exemption period varies by county.
• See Iowa Code § 423.3 for the full statutory list of additional exemptions—including for vehicles, newspapers, irrigation equipment, fuel, prosthetics and hearing aids, manufacturing supplies, telecommunications, residential utilities, and many others not detailed here.

Note: Iowa’s major exemptions list is regularly updated by legislative action. For example, the removal of the computer/computer peripherals exemption for certain commercial entities is effective for purchases made on or after January 1, 2024. The new web search portal exemption begins for qualifying construction completed on or after June 6, 2025. The new honeybee exemption is effective July 1, 2026. Users should consult the latest official code for other targeted and nuanced exemptions.

Iowa applies destination-based sourcing rules for sales and use tax on tangible personal property, specified digital products, and taxable services. Iowa sales tax or use tax only applies if the sale is sourced to Iowa under the rules in Iowa Code § 423.15. Iowa's sourcing statute implements the Streamlined Sales and Use Tax Agreement (SSUTA) destination sourcing framework.

General Sourcing Rules for Tangible Personal Property and Specified Digital Products

Iowa Code § 423.15(1) establishes a five-tier cascade of sourcing rules for sales of tangible personal property and specified digital products. Sellers apply the first rule that yields a definite location, in the following order:

1. Product received by purchaser at seller's business location. The sale is sourced to the seller's business location where the purchaser receives the product. This applies when the buyer picks up the item in person at a retail store or seller location.

1. Product shipped or delivered to purchaser. When the product is shipped or delivered by the seller or by common carrier to an address known to the seller, the sale is sourced to the delivery address. This is the delivery destination, regardless of FOB terms, the shipping company's location, or whether the seller uses its own vehicle or a third-party carrier. Iowa Admin. Code r. 701-205.6 (formerly r. 701-223.6) explicitly states that "the terms of a sale as F.O.B. (origin) are irrelevant for purposes of sourcing a sale," and "the sale of a product delivered to a shipping company is not sourced to the location of the shipping company."

1. Purchaser's address obtained during consummation of the sale. If the first two rules do not apply, the sale is sourced to the location indicated by an address for the purchaser obtained during the consummation of the sale, including the address of a purchaser's payment instrument (such as a credit card billing address) if no other address is available, when use of this address does not constitute bad faith.

1. Address from which the product is shipped or first made available. When the first three rules do not apply—including when the seller lacks sufficient information to apply the previous rules—the sale is sourced to the address from which tangible personal property was shipped, from which the specified digital product or computer software delivered electronically was first available for transmission by the seller, or from which the service was provided, disregarding for these purposes any location that merely provided the digital transfer of the product sold.

1. Fallback: seller's address. Iowa Code § 423.15(1)(e) provides a fallback when none of the previous rules apply.

Sourcing Rules for Taxable Services

Iowa Admin. Code r. 701-205.2 (formerly r. 701-223.2) provides that retailers providing taxable services in Iowa must source those sales using the destination sourcing requirements described in Iowa Code § 423.15. The location where the result of a service is received, first used, or could potentially be first used by the purchaser or the purchaser's donee determines the sourcing.

For services performed on tangible personal property, Iowa Admin. Code r. 701-205.3 clarifies that the service is sourced to the location where the purchaser (or the purchaser's donee) regains possession or can potentially make first use of the tangible personal property on which the seller performed the service. The location where the seller performs the service is not determinative of where the purchaser receives the service. The terms "receive" and "receipt" do not include possession by a shipping company on behalf of the purchaser; when a shipping company delivers tangible personal property on which the service was performed, the service is deemed received where the shipping company delivers the property to the purchaser.

For example, if an Iowa resident takes a lawnmower to an Illinois repair shop and picks it up in Illinois, the service is sourced to Illinois (though Iowa use tax may apply on subsequent use in Iowa). But if the Illinois shop delivers the repaired lawnmower to the Iowa resident's home in Iowa, the service is sourced to Iowa and Iowa sales tax applies.

For tickets or admissions to places of amusement, fairs, and athletic events, Iowa Admin. Code r. 701-205.5 provides that sales are sourced in the same manner as services, using the destination sourcing requirements. Generally, the sale of a service is sourced to the location where the purchaser makes first use of the service. In the case of an event that the purchaser attends at a physical location, first use occurs at the location of the event, regardless of where the ticket is purchased or delivered.

Leases and Rentals of Tangible Personal Property

Iowa Code § 423.15(2) provides that the lease or rental of tangible personal property (other than transportation equipment or property subject to special rules in Iowa Code § 423.16) requiring recurring periodic payments is sourced to the primary property location for each period covered by the payment. The primary property location is the address for the property provided by the lessee that is available to the lessor from its records maintained in the ordinary course of business, when use of this address does not constitute bad faith. For a lease or rental that does not require recurring periodic payments, the payment is sourced the same as a retail sale in accordance with Iowa Code § 423.15(1).

Application to Local Option Sales Tax

Iowa's destination sourcing rules determine not only whether Iowa state sales tax applies, but also which local jurisdiction's local option sales tax applies. Retailers use the same destination-based sourcing rules under Iowa Code § 423.15 and Iowa Admin. Code r. 701-205 to determine whether a sale is subject to local option tax and in which jurisdiction the tax applies. When a product is delivered to a purchaser's address in an Iowa city that imposes the one percent local option sales tax, the retailer must collect both the six percent state sales tax and the one percent local option tax.

Exceptions and Special Rules

Iowa Code § 423.16 lists specific transactions to which the general sourcing rules in Iowa Code § 423.15 do not apply, including sales of motor vehicles, trailers, semitrailers, aircraft, watercraft, modular homes, manufactured homes, and mobile homes. These transactions have separate sourcing rules specified in § 423.16.

Iowa Code § 423.19 provides special sourcing rules for direct mail. Iowa Code § 423.20 provides separate sourcing rules for telecommunications services.

Items Withdrawn from Inventory by a Manufacturer

Iowa Admin. Code r. 701-205.6(7) (formerly r. 701-223.6(7)) provides that when a manufacturer manufactures tangible personal property and uses the property for any purpose except resale or processing, such use is subject to sales tax and is sourced to the county in which the manufacturer first used the property. Taxable use includes using such property as building materials, supplies, or equipment in the performance of a construction contract. Tax is computed upon the cost to fabricate the property.

Direct answer: Iowa generally treats drop shipment transactions as taxable retail sales to the Iowa customer, and permits sellers to claim a resale exemption if proper documentation is provided. If an out-of-state seller directs a third-party supplier (drop shipper) to ship goods directly to an Iowa customer, the drop shipper is required to collect Iowa sales tax unless the sale for resale is properly documented. Iowa accepts resale and exemption certificates issued by other states when the purchaser is not required to hold an Iowa sales tax permit.

Why: Under Iowa Code § 423.3(2), sales for resale are exempt from Iowa sales tax. Iowa Admin. Code r. 701-223.5(3) (now renumbered in ch. 205) and Iowa Department of Revenue guidance confirm the application of resale exemptions to drop shipment transactions. The Streamlined Sales and Use Tax Agreement (SSUTA), adopted by Iowa, requires Iowa to accept multi-state exemption certificates and to honor out-of-state registration numbers in certain circumstances. This means an out-of-state seller without a physical presence in Iowa, who is not required to be registered but purchases from an Iowa supplier (drop shipper) for shipment to an Iowa customer, may document exemption using their home-state resale or exemption certificate, or using the SSUTA Multistate Uniform Sales & Use Tax Exemption Certificate.

The Iowa drop shipper must have a valid exemption certificate to relieve itself of sales tax collection responsibility. If the valid exemption certificate is not provided, the drop shipper is responsible for collecting Iowa sales tax from the purchaser. If the Iowa customer is the end user, tax applies to the retail sale to the customer.

Code r. 701-205.5(3) (sellers accepting exemption certificates), Iowa DOR Sales and Use Tax Guide ("Drop Shipments" section), and Iowa DOR "Exemption Certificates" guidance. Iowa also participates in the Streamlined Sales and Use Tax Agreement (SSUTA), which is codified by Iowa Code § 423.42 and requires member states to accept uniform exemption certificates (per SSUTA § 317).

Iowa DOR guidance states: "If an out-of-state retailer does not have an Iowa sales tax permit number, the retailer may use its home state permit number on the exemption certificate, or may indicate that it is not required to hold a permit number. Iowa is required by the Streamlined Sales and Use Tax Agreement to accept certificates from other states."

Caution / review status: Not yet human confirmed. Some Iowa Admin. Code cross-references were renumbered as of 2024; verified current numbering. The treatment of drop shipment scenarios is supported by statute, regulation, and explicit DOR guidance. If reseller documentation is absent, drop shipper is liable for tax.

Iowa's statewide sales and use tax rates have changed multiple times since the initial imposition of the tax in 1934. The following timeline presents the effective dates and percentages of major rate changes, based exclusively on primary sources from the Iowa Department of Revenue.

Timeline of Statewide Iowa Sales and Use Tax Rate Changes:

• March 15, 1934: Iowa enacts the statewide retail sales tax at a rate of 2%. Use tax is introduced at the same rate.
• July 1, 1955: Statewide rate raised to 2.5%.
• July 1, 1967: Statewide rate increased to 3%.
• July 1, 1983: Statewide rate increased to 4%.
• May 13, 1987: Statewide rate increased to 4.5%.
• July 1, 1992: Statewide rate increased to 5%.
• July 1, 2008: Statewide rate increased to 6%, where it remains as of June 2026.

The statewide rate applies to all taxable sales of tangible personal property and enumerated services unless specifically exempted or subject to local option add-on taxes. Throughout these changes, Iowa’s use tax rate has remained equal to the sales tax rate.

Notable Legal Authority

• The rate increases and effective dates are codified primarily in Iowa Code § 423.2 and chronicled in official Department of Revenue tax rate history publications.
• Scheduled future reduction: Iowa Code § 423.2, subsection 12, establishes that the sales tax rate will drop from 6% to 5% on January 1, 2051, unless amended by future legislation.
