Farm purchases and sales are not covered by one nationwide sales-tax exemption. Whether a transaction is taxable depends on the state and sometimes locality, what is bought or sold, how it is used, who sells it, and what proof the state requires. Being a farmer by itself does not make every purchase exempt. Check the rules where the sale or use occurs before relying on an exemption.
Are farm purchases automatically exempt from sales tax?
No. States set their own agricultural exemptions, rates, definitions, forms, and record rules. A farmer may qualify for an exemption on one item used in agricultural production but owe tax on another purchase for personal use, farm maintenance, or a nonqualifying activity. Iowa’s Department of Revenue puts the point plainly in its Farmers Guide to Iowa Taxes: “Just because something is purchased by a farmer, it is NOT automatically tax exempt.” That is Iowa guidance, but the underlying caution applies when checking any state’s rules.
For each transaction, check the state and locality where the sale or use takes place, whether it is a purchase, sale, rental, or resale, the product or service, its actual use, the seller and sales channel, the applicable rate or exemption category, and the documentation and retention rules. An exemption in one state—or for one use—does not establish the treatment elsewhere.
What certificate or proof do I need to buy farm supplies tax-free?
Follow the state’s procedure for the specific transaction. A certificate, card, or other proof documents an exemption only when the law already allows it; it does not turn a taxable purchase into an exempt one. Procedures differ:

- Florida: Qualifying farmers may use a Farm Tax Exempt Agricultural Materials (TEAM) Card in place of presenting a paper certificate for each purchase. The card does not create or expand exemptions in Florida law. Eligible farmers who do not have or qualify for a card may continue using paper exemption certificates, and dealers must document exempt sales to cardholders.
- Alabama: The Department of Revenue says it does not issue a general farmer exemption certificate. It identifies a statutory agricultural-purpose form for certain transactions. Some farming products receive a lower farming rate rather than a full exemption, so check which treatment applies.
- Tennessee: A qualifying farmer must present one of the proofs accepted by the state to the seller. Tennessee guidance describes certificates as valid for a four-year period and explains renewal; confirm the current period and process with the state before applying or relying on an existing certificate.
- Iowa: A certificate is required for some energy-use exemptions. The guide distinguishes qualifying agricultural production from activities outside that definition.
- Minnesota: Sellers must collect tax unless an exemption applies. A completed Form ST3 supports exempt sales where required.
- Kansas and Louisiana: Kansas’s ST-28F combines four agribusiness exemptions, including farm machinery and equipment, items consumed in production, and agricultural propane. Louisiana’s R-1007 is for commercial farmers and requires a commercial-farmer certification attachment; its instructions distinguish eligible farm-related purchases from feed for animals kept for personal use.
These examples illustrate different state procedures; they are not interchangeable. Use the current state form and instructions, and ask the revenue department whether the documentation covers the precise item and use.
Are farm equipment, feed, seed, fertilizer, and fuel exempt?
There is no reliable nationwide yes-or-no answer by product category. The item’s use, the operation, and state-specific definitions matter. Some states exempt particular qualifying inputs or uses; another may tax the same item, apply a reduced rate, or require a certificate. Do not assume that a product is exempt just because it is commonly used on farms.

For example, Tennessee lists tangible personal property used primarily in qualifying agricultural operations, certain fuels, seeds and plants, fertilizer, pesticides, livestock and poultry feeds, and livestock drugs among qualifying categories. That list is subject to Tennessee’s requirements and does not establish treatment in other states. Alabama’s guidance warns that many farming products are not exempt even though some receive a lower farming rate. Washington says machinery, combines, irrigation systems, vehicles, parts, tools, and cleaning materials sold or rented to farmers are generally retail transactions unless a specific exemption applies; it describes a qualifying replacement-part exemption for eligible farmers.
Before buying, verify the precise item, whether it is new or a replacement part, how and where it will be used, whether the use is direct or primary agricultural production under the state definition, and what proof the seller needs. If a purchase has both farm and personal uses, do not assume the entire transaction qualifies; ask the state how mixed use is treated.

Sometimes. The answer can depend on the product, whether it is sold by its producer, whether the buyer is an end user or a reseller, and whether the sale is retail, wholesale, or through an established place of business. A farm-produced item is not automatically exempt at every point of sale.
- Iowa: Sales of grain, livestock, and other farm or garden products are usually exempt when sold for resale, processing, or human consumption. The guide also identifies taxable end-user examples, so confirm the buyer and purpose rather than treating every farm-product sale alike.
- Washington: The state distinguishes wholesale sales to farmers from retail sales. Its guidance identifies some farm-produced goods sold at retail—including flowers, plants, trees, shrubs, soap made from goat’s milk, and candles—as subject to retail sales tax.
- Mississippi: Certain farm products sold by the producer are exempt, but the exemption has an exception for sales through an established place of business. The state also identifies particular agricultural inputs and packaging situations; the listed categories and conditions should not be generalized to other states.
- Minnesota: Examples of taxable sales include animals sold as farm-working stock and plants or seeds sold for home gardens. Examples of nontaxable sales include agricultural animal feed and produce such as eggs, honey, fruits, and vegetables. Sellers must collect tax unless an exemption applies, and Form ST3 supports exempt sales where required.
These examples are specific to the named states and categories. If you sell at a farm stand, farmers market, online, through a distributor, or from an established business location, check the state’s rules for that channel and product before deciding whether to collect tax.

What records should I keep for a farm sales-tax exemption?
Keep records that let you and the seller substantiate the transaction and the qualifying use. The exact requirements and retention period depend on state law. A practical file may include:
- Itemized invoices and receipts showing what was purchased, when, and from whom.
- The exemption certificate, card information, or other proof given to the seller, plus any required renewal or application documents.
- Records of the item’s actual use in the agricultural operation, especially where eligibility turns on qualifying production or a particular use.
- Sales records identifying the product, buyer, sales channel, and any exemption claimed, along with completed certificates where required.
- Records supporting how tax was handled when an item had mixed, personal, or changed use.
Do not treat a seller’s acceptance of a certificate as a guarantee that the purchase qualifies. Washington’s guidance notes that a farmer who uses an untaxed item in Washington may owe use tax if that item is not exempt. Ask the state’s revenue department how to report tax due and what records to retain if an untaxed purchase is later used in a taxable way.

Does the IRS create a farm sales-tax exemption?
No. The IRS’s 2025 Farmer’s Tax Guide addresses federal income-tax reporting, not a nationwide state sales-tax exemption. It says state and local general sales taxes paid on nondepreciable farm-business expense items are included in their cost, and sales taxes on farm-business assets are included in depreciable cost. That is how paid sales tax is treated for federal income-tax purposes; it does not exempt a state-taxable purchase.
When should I contact the state or a tax professional?
Contact the revenue department for the state where the transaction occurs when the product, use, sales channel, rate, certificate, or reporting obligation is unclear. A qualified tax professional familiar with that state’s agricultural rules can help with mixed-use equipment, multiple locations, sales through several channels, exemption documentation, or a possible use-tax liability. State law, rates, forms, eligibility, and renewal procedures can change; confirm current instructions before a transaction, particularly when relying on an older guide or certificate.
The examples above reflect official guidance available as of October 3, 2026, and are illustrations rather than a determination for any particular farm. Iowa’s guide notes a honeybee sales-tax change effective July 1, 2026, another reason to verify the current rules rather than relying on old summaries. Louisiana’s rules have also changed recently, and Florida TEAM procedures and Tennessee certificate renewal details warrant current confirmation.
