Introduction
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
- 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
- Production of Christmas trees
- 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/Use Tax Issues for Farming Operations
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

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.

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 excise 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.

Income Tax Withholding on Agricultural Labor
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 www.irs.gov
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 Iowa withholding agents are required to submit a completed Verified Summary of Payments Report (VSP) by the last day of February for withholding payments made in the prior calendar year. The VSP is submitted online through eFile & Pay or by touch-tone telephone.
W-2
Employers
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 www.irs.gov/, or from a commercial printer.
Employees:
If you need a copy of your W-2, first ask your employer. Since employers are not required to send copies of W-2s to the Iowa Department of Revenue, we are not able to furnish them to you. 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 www.ssa.gov 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.
Iowa Fuel Tax
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:
- File your Iowa income tax return with form IA 4136; see income tax forms
- No permit needed
or
- Obtain a refund permit; Iowa Fuel Tax Refund Permit Application (80-005)
- Use call-in system
- See 85-030 Information on Motor Fuel Tax Refund Claims (pdf)
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.
Agribusiness Sales/Use Tax Issues
This section is written for cooperatives, elevators, agricultural-chemical dealers, and fertilizer dealers.
Exempt
- Machinery and equipment used directly and primarily in the production of agricultural products
- 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)
Taxable
- All vehicles subject to registration
- All equipment attached to a vehicle subject to registration
- Labor to repair exempt machinery and equipment
- Parts not separately itemized from labor
- Grain testing
- Grain storage
- Pest eradication
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
Exempt if used to till fields and harvest crops
Taxable if purchased by an elevator to primarily haul grain from an unloading dock to a silo
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
A co-op uses a skidloader 100% of the time to load bags of seed, fertilizer, and feed on customer’s trucks.
