Farmers Guide to Iowa Taxes


This publication is intended as a general guide. For additional details reference Iowa Administrative Code Chapter 701-226: Agricultural Rules.

"Production of Agricultural Products" begins with:

  • Cultivation of land previously cleared for planting crops; or
  • The purchase or breeding of livestock or domesticated fowl.

"Production of Agricultural Products" ceases when:

  • An agricultural product has been transported to the point where it will be sold by the farmer or processed for further use.

"Agricultural production" includes the following:

  • The raising of crops or livestock for market on an acreage
  • Raising of flowering, ornamental, or vegetable plants in commercial greenhouses or elsewhere for sale in the ordinary course of business
  • Aquaculture
  • Silviculture
  • Nurseries
  • Ranches
  • Orchards
  • Dairies
  • Raising catfish
  • Feedlot operations, whether or not crops to feed the livestock are grown on the property or if the livestock are owned by feedlot operators
  • Operations that grow and raise seed for sale to nurseries, ranches, orchards, and dairies.

Examples of activities that are not "agricultural production":

  • Logging
  • Beekeeping
  • Raising mink and other nondomesticated furbearing animals
  • Raising nondomesticated fowl (other than ostriches, rheas, and emus)
  • Land placed in the federal government’s Conservation Reserve Program (CRP)
  • Clearing or preparation of previously uncultivated land
  • Creation of farm ponds
  • Construction of machine sheds, confinement facilities, storage bins, or other farm buildings
  • Sales by Farming Operations

    Usually exempt for resale, processing, or human consumption:

    • Grain
    • Livestock
    • Any other farm or garden product

    Examples of items that are taxable when sold to the ultimate user:

    • Pet food
    • Grain for race horses

    Purchases by Farming Operations

    Purchases by farmers may be exempt from Iowa sales and / or use tax. Just because something is purchased by a farmer, it is NOT automatically tax exempt. Anyone claiming exemption must be able to show they are entitled to it.

    See Purchases and Sales: Taxable and Exempt below.

    Use Tax

    Taxable purchases from suppliers who do not collect Iowa sales tax are subject to Iowa use tax if the purchase is for use in Iowa. Anyone making these kinds of purchases regularly must register for a consumer's use tax permit. A consumer's use tax permit is not needed for occasional purchases of this type, but the use tax must still be paid to Iowa.

    See Iowa Consumer's Use Tax.

  • Auctions

    Exempt if:

    • Sale of qualifying farm machinery or equipment
    • Casual sale*

    *A casual sale is one that does not occur on a regular basis (nonrecurring). The seller does not usually sell goods or taxable services for profit. If the seller does, the sale must be outside the regular course of business to be a casual sale. Two separate selling events outside the regular course of business within a 12-month period are considered nonrecurring.

    Taxable if:

    The casual sale exemption does not apply if there are three separate selling events within a 12-month period. Tax applies beginning with the third separate selling event. View Iowa Administrative Code 701-18.28 for additional details.

    • Energy / fuel used in heating or cooling (not general lighting) of livestock buildings on the farm
    • Fuel used in an implement of husbandry, such as a tractor or combine
    • Energy / fuel used to dry grain


    Energy used for other purposes, such as recreation, hobbies, lighting, or for farm shops

    State sales tax does not apply to residential energy use; however, local option sales tax, if any, does apply.

    Exemption certificate for energy used in agricultural production

    To claim exemption, complete Iowa form 31-113 (pdf) and give it to your supplier. The energy supplier will require an updated form at least every three years. Documentation of the energy used for agricultural production must be provided to the utility company.

    When filling out the exemption certificate for your utility company, you will need to show what percent of your total energy consumption is for agricultural production. Separate meters for production and non-production use are ideal for determining the exempt and nonexempt energy percentages. However, a separate meter for non-production use is not practical for some farmers. If you do not have production and non-production uses metered separately, you need to determine the percentage of total energy used in agricultural production.

    Your previous year's monthly utility bills can be used as a guide to help you determine your total annual use. Ordinarily, the 12-month period immediately preceding the date you apply for exemption is used. However, your circumstances can dictate that you use a shorter or longer period than 12 months or that you use a 12-month period other than the immediately preceding one. If for some reason your usage last year was not typical, select a 12-month period that is more representative; be sure to have adequate documentation. Your utility company may be able to assist you.

    Wind Energy Conversion


    • Materials used to manufacture, install, or construct property used to convert wind energy to electrical energy
  • A seller must obtain a completed exemption certificate from the purchaser to verify the purchase qualifies for the exemption.

  • Iowa Code section 423.3, subsection 16A, to exempt the sale of a grain bin from sales and use tax. The exemption went into effect July 1, 2019. The Department of Revenue engaged in the process of drafting administrative rules to provide binding guidance for taxpayers. Those rules underwent several rounds of revisions after receiving useful feedback from a wide variety of stakeholders, such as grain bin manufacturers, retailers, contractors, and others interested in the exemption. The rules have now been adopted and become effective on August 19, 2020.

    The exemption itself exempts the following from sales and use tax: “the sales price from the sale of a grain bin, including material or replacement parts used to construct or repair a grain bin.” It defines “grain bin” as “property that is vented and covered with corrugated metal or similar material, and that is primarily used to hold loose grain for drying or storage.”

    In general, materials that are permanently attached to a grain bin and are required to hold loose grain for drying or storage are used to construct a grain bin and thus exempt from sales and use tax. In contrast, generally, equipment used to move loose grain into or out of a grain bin is taxable.

    The purchaser of a grain bin (or, more precisely, the sponsor of a grain bin contract) does not need to be a farmer; the exemption is available to any person or entity that purchases a grain bin. To claim the exemption, the purchaser (“sponsor”) should present a sales tax exemption certificate to the seller (“contractor”), who should honor the certificate if it is otherwise complete.

    It is important to note that grain bins are real property, and grain bin materials are building materials as that term is discussed in Iowa Administrative Code rule 701—219.3. This means that a contractor is responsible to account for use tax on grain bin materials. The new administrative rule, Iowa Administrative Code rule 701—226.20, provides a variety of examples to illustrate how taxpayers may claim the exemption. Please refer to the rule for further details.

    It is also important to note that the exemption became effective July 1, 2019, even though the rules became effective afterward. If you feel you incorrectly paid tax on a grain bin after July 1, 2019, you may request a refund by submitting an IA 843 Refund Return.

  • Iowa income tax withholding is applied to the same wages and compensation as federal income tax withholding.

    Registering as a Withholding Agent

    Employers required to withhold must register with the State of Iowa and the Internal Revenue Service as a withholding agent. There is no fee for registering.

    First register with the Internal Revenue Service to obtain a Federal Employer Identification Number (FEIN). You may call 1-800-829-4933 instead of applying online.

    Then register online with Iowa or use Iowa Business Tax Permit Registration, 78-005 (pdf).

    Filing and Paying Withholding Tax

    Iowa withholding returns are submitted electronically through the eFile & Pay system. Once you are registered as a withholding agent, the Department will send you a Business eFile Number (BEN). This number is necessary to access the paperless system.

    Every withholding agent is required to file a return for each period during the calendar year, even if tax was not withheld.

    Penalty and Interest on Delinquent Returns

    Returns and deposits must be filed no later than the due date to be timely. After the due date the amount of tax due is subject to penalty and interest.

    See Penalty and Interest.

    Iowa W-4

    Employees must complete the federal and the Iowa W-4.

    The Federal W-4 (pdf) is available on the IRS website at

    The Iowa W-4 is available online (pdf).

    Within 15 days, each new hire and rehire is required to complete and sign an Iowa W-4. It must show the number of allowances the employee is claiming. If for any reason the employee does not complete an IA W-4, the employer must withhold at zero allowances.

    Some employees are exempt from withholding. See the W-4 instructions.

    Employers must keep copies of W-4 forms in their files for at least four years.

    Verified Summary of Payments Report

    All withholding agents must submit a completed Verified Summary of Payments Report (VSP) by February 15 for withholding payments made in the prior calendar year. The VSP is submitted online through eFile & Pay.



    Employers are not required to send copies of W-2s or 1099s to the state of Iowa with the VSP. Employers are still required to keep copies of the W-2s and 1099s for at least four years from the end of the year for which the forms apply.

    W-2s must be given to employees on or before the last day of January following the tax year or within 30 days of the time the last wage payment is received if requested by the employee.

    Blank W-2s may be obtained by contacting the IRS at 1-800-829-3676, ordering online from the IRS at, or from a commercial printer.


    If you need a copy of your W-2, first ask your employer. The Iowa Department of Revenue is not able to furnish W-2s. If you are unable to obtain a copy from your employer, here are some other possible options:

    • Social Security Administration (SSA) - will provide copies of Forms W-2 for retirement purposes at no charge and for other than retirement purposes for a fee. Call 1–800–772–1213, or visit the SSA website at  for instructions on how to obtain wage information from the SSA.
    • Internal Revenue Service (IRS) – will provide an exact copy of a previously filed and processed tax return with attachments (including Form W-2). You should complete Form 4506, Request for Copy of Tax Return, and mail it to the address listed in the instructions. A fee will be charged for each tax year requested.

    See Iowa Withholding Tax Information.

  • Tax paid on fuel used in agricultural production is eligible for credit or refund.

    Motor Fuel Credits and Refunds

    Credit or refund of fuel tax:


    Dyed Diesel Fuel

    Dyed diesel fuel may be purchased free of Iowa fuel tax. Therefore, farmers should purchase dyed diesel fuel for agricultural use whenever possible. Since fuel tax will not be charged at the time of purchase, no refund or credit will be necessary. Dyed diesel cannot be used in registered vehicles.

    Fuel used to power implements engaged in agricultural production is exempt from sales/use tax.

  • This section is written for cooperatives, elevators, agricultural-chemical dealers, and fertilizer dealers.

    • Machinery and equipment used directly and primarily in a manufacturing process
    • Replacement parts for exempt machinery and equipment
    • Computers used in processing or storage of data by a commercial enterprise (farmers cannot purchase computers tax free, but an agribusiness may be eligible for exemption)

    • All equipment attached to a vehicle subject to registration
    • Labor to repair exempt machinery and equipment
    • Parts not separately itemized from labor
    • Grain testing

    Taxable vs. Exempt Examples

    Example 1:  Nurse Tank (for example, an anhydrous ammonia tank)

    Taxable if attached to a vehicle subject to registration
    Exempt if drawn by a self-propelled implement of husbandry used in agricultural production

    Example 2: Grain Vacuum Conveyor

    Taxable if used at an elevator
    Exempt if used directly and primarily on a farm in agricultural production

    Example 3: Tractor

    Taxable if purchased by an elevator to primarily haul grain from an unloading dock to a silo
    Exempt if used to till fields and harvest crops

    Example 4: Skidloader

    Exempt if primarily used in agricultural production. A co-op uses a skidloader 60% of the time to clean the feedlot of its livestock operation. The remaining 40% is used to handle fertilizer and do utility work on the co-op premises. The skidloader is exempt because it is primarily (more than 50%) used in agricultural production.
    Taxable if a co-op uses a skidloader 100% of the time to load bags of seed, fertilizer, and feed on customer’s trucks.
