If you want to change or end a farm lease in Iowa for the 2027 crop year, your deadline is September 1. Miss it and Iowa Code 562.6 renews the lease automatically, on the same terms, for another full year. That applies to handshake leases and written ones, to one-year deals and to multi-year deals that are expiring. The cost is not theoretical. Iowa State’s 2026 survey puts the state average cash rent at $270 an acre and the northwest district at $290. A rent set five years ago and never revisited is often well under both, and every year you leave it alone is income you do not get back. The deadline decides whether you fix it for 2027 or wait until 2028.
Key takeaways
- September 1 is the hard deadline. Written notice on or before that date, or the lease renews on the same terms for another crop year.
- The rule applies to oral leases exactly as it applies to written ones.
- Iowa’s 2026 average cash rent is $270 an acre statewide, $290 in the northwest district.
- A below-market lease costs you rent every year. Its effect on what the farm would sell for is usually much smaller than people assume.
- The lease does not end when the owner dies. Heirs inherit the tenancy and have to serve their own notice.
What happens if you miss September 1?
Nothing happens. That is the problem.
Under Iowa Code chapter 562, a farm tenancy continues into the next crop year on the same terms and conditions unless one party serves the other with written notice of termination on or before September 1. Iowa farm leases run March 1 to March 1, so a notice served this year ends the lease on March 1, 2027.
Three things about that rule catch landowners out. It covers oral leases, so the handshake your father made with the neighbor in 1998 renews every year exactly like a signed document. It covers expiring multi-year leases, so a written five-year lease with a stated end date still rolls another year without notice. And a renewed lease renews again, and again, until somebody serves notice. Iowa State’s Center for Agricultural Law and Taxation calls this the most misunderstood part of Iowa farm lease law, and they are right.
The old exemption for tracts under 40 acres no longer applies unless the ground’s primary use is an animal feeding operation.
How do you know whether your cash rent is behind?
Start with the survey, then do the math on your own farm.
Iowa State’s 2026 Cash Rental Rates for Iowa survey put the statewide average at $270 per crop acre, down a dollar from 2025. The northwest district averaged $290, up $2 on the year and still $14 under its 2024 high. By land quality the year was flat: high-quality ground down $3, medium down $2, low-quality up $1. The full survey breaks results down county by county.
District averages are a starting point, not your number. The method that actually fits a specific farm is the one ISU publishes in Computing a Cropland Cash Rental Rate: take your farm’s weighted CSR2, the Corn Suitability Rating that scores Iowa soil productivity, and multiply it by the rent per CSR2 point reported for your county. ISU’s worked example uses $3.20 a point, so 80 CSR2 pencils out to $256 an acre.
Run your own farm through it. A 90 CSR2 tract at that same $3.20 a point comes to $288. If you are collecting $240, you are $48 an acre behind. On 160 acres that is $7,680 a year, and if nobody has looked at it in five years, roughly $38,000.
ISU says plainly that its survey reports opinions about typical rents and should not be used to set a price without discussing the individual farm. Agreed. Use it to learn whether you are in the neighborhood, and use somebody who knows your ground to learn what it should actually bring.
What does an outdated lease actually cost you?
The rent, and only the rent, but every single year.
That is the honest accounting, and it is bad enough. A handshake rent that has not moved since 2021 is not loyalty. It is a decision you stopped making. Your property taxes moved. Your tile repairs moved. The yields on your ground almost certainly moved.
Sometimes the review comes back the other way. Rents here have been flat to slightly down for two years, so if your tenant has paid a strong number through a run of poor crop prices, you may already be at or above market and the right move is to leave it alone. Knowing that is worth as much as finding out you were short.
Does a below-market lease lower what your farm is worth?
Less than you have probably been told, and this is where a lot of advice on this subject goes wrong.
Iowa farmland is priced off comparable sales, not off a capitalization rate. Buyers here underwrite the dirt: CSR2, tile, FSA crop acres, location, access. They are not valuing your rent roll, because they know the rent resets. That is the flip side of 562.6. A buyer who closes in the fall serves his own notice by September 1 and has the farm on his terms the following March.
Where an old lease does cost you at sale is timing, not capitalized income. A farm already committed for the coming crop year is worth less to an operator who wanted it for his own planter, and that shows up as a softer bid or fewer bidders, not as a lower appraisal. Sell a farm with the tenancy locked in and you have narrowed your buyer pool.
So do not fix your lease because you are worried about an appraisal. Fix it because it is your income.
What happens to the lease when the owner dies?
It keeps going. This is the part heirs get wrong most often.
Iowa Code 562.8 addresses farmland passing to a successor. The tenancy continues until the holder of the successor interest serves notice of termination the way chapter 562 requires. An heir who inherits in October and assumes a fresh start in spring finds the tenant in place through the following March 1 at the old rate, because nobody served notice by September 1. Narrow exceptions exist where a trust provision or specific commitment controls instead, which is a conversation for the estate’s attorney.
On the tax side, the common worry runs backward. Inherited farmland generally receives a stepped-up basis to fair market value as of the date of death, and that basis is what limits capital gains tax if the heirs sell. A low valuation produces a low basis and a larger taxable gain later. The federal estate tax exemption is high enough that most farm estates never owe estate tax at all, while basis affects nearly every family that eventually sells. Wanting a small number on the estate appraisal usually works against the heirs.
That is the general mechanic, not advice for your family. Estate valuation, basis, and elections are specific to the estate and the rules change. Get your CPA and your attorney on it before anything is filed.
How do you serve a notice that holds up?
Iowa Code 562.7 gives three ways, and the courts read them strictly.
- Personal delivery with a signed acceptance of service from the other party, on or before September 1.
- Service the way you would start a lawsuit, through a sheriff or process server with an affidavit of service. If personal service cannot be obtained, notice by publication is available.
- Certified mail sent before September 1, which is what most people use. Service is complete when the notice is sealed, properly addressed to the last known mailing address, stamped and deposited with the postal service.
Regular mail does not count, and courts have held that against landlords even where the tenant admitted receiving it. Keep the certified mail receipt, and set termination for March 1. Have your attorney review the notice before it goes out, because a defective one buys the tenant another year and you will not find out until it is too late to fix.
Does terminating mean losing a good tenant?
No, and this is the misunderstanding that costs Iowa landowners the most money.
A termination notice is not a firing. It is the only mechanism the statute gives you to reopen terms. Plenty of landowners serve notice in August and re-sign the same operator in October at a current rate, and the relationship is fine because the tenant understood the paperwork. Tenants serve notice on landlords for the same reason.
Where this goes badly is when the notice is a surprise. Call your tenant first, say you are reviewing the rent and that a notice is coming to preserve your options, then send it. Operators worth keeping are not rattled by a landowner who runs the farm like a business, and there are better ways to keep a good tenant than an underpriced rent.
This is most of what we do. Our farm management practice negotiates leases across cash rent, crop share, flex, and custom farming, keeps the notice calendar so nothing gets missed, and prices ground from what we see it rent for in Clay, Buena Vista, Palo Alto, and O’Brien counties rather than from a district average. Travis Johnson holds the Accredited Farm Manager designation from the American Society of Farm Managers and Rural Appraisers, and we manage more than 40,000 acres.
Frequently asked questions
Does the September 1 deadline apply to a handshake lease?
Yes. Iowa’s auto-renewal rule applies to oral leases exactly as it applies to written ones. A verbal agreement with no paperwork at all renews every year on its existing terms until somebody serves proper written notice.
Can I just tell my tenant I am ending the lease?
A conversation is not service. Chapter 562 requires one of the three statutory methods, and personal delivery only counts if you obtain a signed acceptance of service. Have the conversation, then serve the notice properly.
Does selling the farm end the lease?
No. The tenancy carries to the new owner, and notice still has to be served by September 1 to end it for the following crop year. Buyers who want possession for the next spring need this handled before closing, which is a good reason to know your lease status before you list.
If I serve notice, when does the lease actually end?
March 1 of the following year. Notice served by September 1, 2026 ends the tenancy March 1, 2027, and the tenant keeps the current crop year.
