The biggest tax benefits of owning agricultural land in Iowa come at three points: every year, when you sell, and when the land passes to your heirs. Each year, Iowa assesses farmland on its productivity rather than its market value, and cash rent is not subject to self-employment tax. When you sell, a 1031 exchange can defer the federal gain, and owners who farmed the ground for 10 years may deduct the gain on their Iowa return. At death, heirs get a stepped-up basis, Iowa no longer has an inheritance tax, and the federal estate tax exemption is $15 million per person in 2026. Which of these you can use depends on whether you farm the land yourself or rent it out.
Key takeaways
- Iowa farmland is assessed on productivity and net earning capacity, not market value.
- Cash rent is not subject to self-employment tax. Crop share income can be, if you materially participate.
- Retired Iowa farmers can make one lifetime election: exclude rent from Iowa income or deduct capital gains, not both.
- Inherited farmland gets a stepped-up basis, and Iowa’s inheritance tax is gone for deaths in 2025 and later.
- Several of these elections are irrevocable. Talk to an ag tax professional before you make one.
How is farmland taxed for property tax in Iowa?
Iowa does not tax farmland on what it would sell for. Agricultural land is assessed on its productivity and net earning capacity, as county assessors explain it. Because the assessment follows what the land earns rather than what it would bring at a sale, it is often well below recent sale prices. That is one of the most valuable benefits of owning farmland here, and it applies whether you farm the land or rent it out.
The Family Farm Tax Credit covers tracts of 10 acres or more that are farmed by the owner or an immediate family member. You apply with your county assessor by November 1 of the first year you claim it, according to Scott County’s assessor page on the credit. If your farm is rented to someone outside the family, it generally will not qualify. Check with your own county assessor.
How is farm rent taxed?
It depends on the kind of lease. Cash rent is rental income. Iowa State’s Center for Agricultural Law and Taxation explains in its review of the tax side of farm leases that cash rent is not subject to self-employment tax and is reported on Schedule E. The trade-off is that it does not count toward Social Security, may be subject to the 3.8% net investment income tax for higher earners, and cash rent landlords cannot use some farm-only breaks such as section 179 expensing. Field tile is depreciated over 15 years.
Crop share is different. A crop share landlord who materially participates in the operation pays self-employment tax on that income and reports it on Schedule F, but can also use farm-only breaks. A crop share landlord who does not materially participate reports on Form 4835, and the income is not subject to self-employment tax.
A retired owner who wants simple income often prefers cash rent. An owner who wants to stay involved, or wants Social Security credit, may prefer a crop share. We compare the two in cash rent vs. crop share.
What tax breaks do retired Iowa farmers get?
Iowa offers retired farmers two state tax breaks, and you can only pick one. Iowa State’s Center for Agricultural Law and Taxation lays out the rules in its guide to Iowa’s tax rules for retired farmers.
- The farm tenancy income exclusion lets an eligible retired farmer exclude rent from a written farm lease from Iowa income, including cash rent, crop share, and flex leases. CRP payments do not qualify.
- The capital gain deduction lets an eligible retired farmer deduct the gain from selling farmland from Iowa income.
To qualify, you generally must be 55 or older or disabled, no longer materially participate in farming, and have owned the land 10 years and materially participated in farming 10 years. Either election is a one-time, irrevocable lifetime choice, and making it rules out the other one and the Beginning Farmer Tax Credit. Iowa’s lower income tax rates have shrunk the value of the rent exclusion over time, so the right choice depends on whether you plan to keep renting the land or sell it. Decide with your tax preparer.
Is there a credit for renting to a beginning farmer?
Yes, and it goes to the landowner. Iowa’s Beginning Farmer Tax Credit pays 5% of the cash rent or 15% of the crop share on a lease of two to five years with a qualifying beginning farmer. Cash rent cannot exceed the county average by more than 30%, and applications are due each year. A retired farmer who has made either lifetime election cannot claim it.
What are the tax breaks when you sell?
Farmland you have held more than a year is generally taxed at federal long-term capital gains rates when you sell it. On land held for decades, the gain can still be large, so three tools matter:
- A 1031 like-kind exchange can defer the federal gain if you reinvest in other real estate held for business or investment. The deadlines are strict. See our 1031 exchange guide for Iowa farmland sellers.
- Iowa’s capital gain deduction can remove the gain from Iowa income for owners who held the land 10 years and materially participated in farming for 10 years, or who qualify as retired farmers.
- An installment sale spreads the gain over the years you receive payments.
The sale method also affects the timing. Our post on timing the sale of your farmland covers how closing dates and tax years interact.
What happens to taxes when land passes to heirs?
This is where the largest tax benefit usually sits.
Under IRS Publication 551, inherited property generally takes a basis equal to its fair market value at the owner’s death. That stepped-up basis can wipe out decades of gain if the heirs sell soon after. Land given away during life usually keeps the giver’s original basis instead.
The federal estate tax exemption is $15 million per person for 2026, so most Iowa farm estates owe no federal estate tax. Iowa’s inheritance tax is repealed for deaths on or after January 1, 2025. Minnesota still has its own estate tax, which matters if you own land or live there. For larger estates, federal special use valuation under section 2032A can still value farmland at its farm-use value rather than market value, with strict rules on continued family farming afterward.
We walk through how basis, gifting, and fair treatment of heirs fit together in our farm succession planning guide.
Do conservation easements cut your taxes?
They can. A conservation easement permanently restricts development on your land, and donating a qualifying easement to a land trust or government agency can produce a federal income tax deduction while you keep owning and farming the ground. The catch is that it is permanent and lowers what the land can sell for, because a future buyer can never develop it. Get an appraisal and an attorney who has done these before.
What mistakes cost farmland owners the most?
- Making an irrevocable election, like Iowa’s retired farmer elections, without running the numbers both ways.
- Gifting appreciated land during life and losing the stepped-up basis.
- Choosing a lease type without knowing how it changes self-employment tax and Social Security.
- Poor records. You need clear records of rent, expenses, improvements, and basis to support every deduction and to figure the gain when you sell.
- Missing deadlines, such as the Family Farm Tax Credit application or the 1031 identification window.
