Tax is not due on the sale or use of certain articles of clothing or footwear if the sales price of the article is less than $100.00 and the sale takes place during a period beginning at 12:01 a.m. on the first Friday in August and ending at 12:00 midnight of the following Saturday.
Eligible purchases of clothing and footwear are exempt from local option sales tax as well as Iowa state sales tax.
Clothing means any article of wearing apparel and typical footwear intended to be worn on or about the human body.
Clothing does not include watches, watchbands, jewelry, umbrellas, sporting equipment, and any special clothing or footwear designed primarily for athletic activity or protective use and not usually considered appropriate for everyday wear.
A manufacturer’s coupon does not reduce the sales price of an item. Therefore, a manufacturer’s coupon cannot be used to reduce the selling price of an item to less than $100.00 in order to qualify for the exemption. However, store coupons and discounts reduce the sales price of an item. Therefore, a store coupon or discount can be used to reduce the sales price of an item to less than $100.00 in order to qualify for the exemption.

To find out if computers are exempt, go to our computers booklet.
A contractor is considered to be the consumer of building materials and supplies purchased for use in a construction contract, and is, therefore, responsible for paying sales tax at the time the purchases are made, or use tax if the purchases were made tax free.
Suppliers that sell to building contractors must charge sales tax on the purchase price of the items. Suppliers should not usually accept sales tax exemption certificates from contractors. Contractors are not allowed to make purchases for resale merely because they have a sales tax permit number.
However, designated exempt entities awarding construction contracts may issue special exemption certificates to contractors and subcontractors, allowing them to purchase, or withdraw from inventory, materials for the contract free from sales tax. See the local government portal for more construction contract registration information.
In some cases, a contractor may sell supplies and materials over the counter. This contractor is referred to as a contractor-retailer and may purchase supplies and materials tax free. The contractor-retailer provides the supplier with a valid sales tax exemption certificate. The contractor-retailer then charges customers sales tax when the items are resold at retail. If the contractor-retailer takes items from inventory for use on a contract, the cost of those materials will be reported as "goods consumed" on the sales tax return and tax is paid at that time.
Suppliers that sell to owners who are building their own structures must charge sales tax on the selling price of the materials, supplies, and equipment. Owners are considered final consumers and their purchases are taxable.
Labor is not subject to sales and use tax if performed on or in connection with new construction, reconstruction, alteration, expansion, or remodeling of a building or structure.
More information is available in our contractors publication.
Instead of the 6% state sales/use tax (and local option tax where applicable), a 5% state excise tax applies to purchases of certain construction equipment. See State Excise Tax on Certain Construction Equipment for more details.
Nonprofit entities, churches, and religious organizations are not automatically exempt from paying state sales taxes on taxable goods and services. This is true even if these entities are exempt from the payment of state and federal income taxes. State sales tax must be paid unless some other general sales tax exemption applies. Local option sales tax must also be paid on purchases made in jurisdictions which impose the tax.
Purchases made for resale are exempt from all sales tax.
In other words, a nonprofit corporation, church, or other religious organization is treated the same as any other private citizen for sales and use tax purposes when purchasing goods and taxable services at retail.
However, sales of items to any Iowa private nonprofit educational institution used for educational purposes are exempt. Sales from fund-raising activities are exempt from sales tax to the extent that the proceeds are used for educational, religious, or charitable purposes. However, the gross receipts from games of skill, games of chance, raffles, and bingo are always subject to sales tax.
More information is available in our publication for nonprofit entities.
Iowa sales tax is filed and remitted electronically through eFile & Pay. The Department does not mail returns.
The Department determines how often sales tax returns are due based on the estimated amount of sales tax collection that the retailer entered on the permit application.
See our filing status information.
Anyone making a retail sale in Iowa must obtain a sales or use tax permit from the Iowa Department of Revenue. Selling without a permit is a serious misdemeanor. The permit is available at no charge. You can apply for your Iowa permit online.
Certain purchases by farmers may be exempt from the Iowa sales and/or use tax. If you claim exemption on any purchase, you must be able to show that you are entitled to it by providing a valid exemption certificate to the seller of the property. A separately completed exemption certificate is not necessary for each similar exempt purchase; if the retailer chooses, a "blanket exemption certificate" on file with a given retailer is sufficient. The exemption certificate (pdf) may be obtained on this site.
Machinery and equipment
Generally, self-propelled implements, implements customarily drawn or attached to a self-propelled implement, or grain dryers used directly and primarily in agricultural production and not subject to registration as a vehicle are exempt.
Also exempt are auxiliary attachments which improve the performance, safety, operation, or efficiency of the farm machinery or equipment.
Certain purchases of non-self-propelled machinery or equipment are exempt from the Iowa sales tax if they are used directly and primarily in dairy or livestock production.
A 5% one-time registration fee is imposed on the purchase prices of vehicles subject to registration and on any implement customarily drawn by or attached to a registered vehicle. This includes camping trailers and livestock trailers.
Farm tractors, combines, and other such vehicles are exempt because they meet all three of the following requirements: they are used directly and primarily in agricultural production, they are self-propelled, and they are not subject to registration.
The purchase of machinery and equipment which will become real property after installation (that is, a substantially permanent part of the farm property) is usually taxable. In general, machinery or equipment is real property if its removal after installation is difficult or if removal substantially lessens the value of the machinery or the location where it was placed.
Exceptions to this general rule exist for certain items. For example, drainage tile is exempt from tax.
Also exempt for livestock or dairy production, aquaculture production, or the production of flowering, ornamental, or vegetable plants are:
- Auger systems
- Curtains and curtain systems
- Drip systems
- Fans and fan systems
- Inlets and shutter or inlet systems
Parts and supplies
Replacement parts used in the operation of eligible farm machinery or equipment are exempt from sales tax.
Oil filters, spark plugs, gas filters, and tires are examples of exempt replacement parts.
Do not confuse replacement parts with supplies, most of which are taxable.
Oil and grease used in the routine maintenance of a tractor, for example, are not considered parts; they are considered supplies. They are taxable.
For more information, go to our farmers guide.
A penalty of 10% will be added to the tax due if the return is not filed by the due date and at least 90% of the correct tax is not paid by the due date.
If the return is filed timely and the tax is not remitted, a penalty of 5% will be added to the tax due if at least 90 percent of the correct tax is not paid by the due date.
The interest rate may change yearly. Interest must be added to delinquent tax at a per month rate, beginning on the due date of the return and accruing each month until you make full payment of all tax, penalty, and interest due.
Through June 30, 2008, Iowa's state sales tax rate was 5%.
Beginning July 1, 2008, the state rate is 6%.
Local option tax is in addition to the state rate.
Local option sales tax has been adopted in most cities and unincorporated areas in Iowa. Local option sales tax is imposed on the gross receipts from sales of tangible personal property. Tax applies if "delivery" of the tangible personal property occurs within a local option sales tax jurisdiction.
Local option sales tax is imposed on a taxable service if the first use of the service occurs, or potentially could occur, within a local option sales tax jurisdiction.
Out-of-state retailers with a physical presence or nexus in Iowa who make deliveries into Iowa must collect Iowa sales tax. If these deliveries occur in a local option jurisdiction, local option sales tax also applies.
Many services are taxable. Persons performing these services at retail must charge Iowa sales tax.
See our list of taxable services.
