A crop share lease is a farmland rental arrangement in which the landowner and the tenant farmer divide the harvest, or its sale proceeds, instead of exchanging a fixed cash payment. The landowner takes an agreed percentage of the crop and the tenant keeps the rest, so both parties’ income rises and falls with yield and prices. That single structural choice shapes almost everything else about the deal: how input costs are split, how each side reports income to the IRS, who insures the crop, and how much risk each party carries in a bad year.
How the Split Works
The most common split for grain crops like corn, soybeans, and wheat is one-third to the landowner and two-thirds to the tenant. On higher-quality or irrigated ground, a 50/50 split is typical because the land itself contributes more to the yield. In some irrigated areas, 40/60 arrangements with the smaller share going to the landowner also appear.
Regional custom drives these numbers more than any statutory formula. The underlying principle is that each party’s share of the crop should roughly reflect their share of the total contribution to production: land, equipment, labor, and inputs combined. Dryland farming tends to default to the traditional one-third/two-thirds; productive irrigated ground pushes the landowner’s share up.
Who Pays for What
Variable expenses that boost yields are generally split in the same proportion as the crop. If the landowner receives one-third of the harvest, the landowner pays one-third of the cost of fertilizer, herbicide, and insecticide. Both parties benefit from better inputs, so both invest proportionally.
Seed is the input that causes the most disagreement. In some regions, both parties split seed cost to match the crop ratio. In others, the tenant bears the full seed expense because it’s treated more like a labor or machinery cost. There’s no single right answer, which is exactly why the lease has to spell it out.
Landowners nearly always pay all property taxes and land-related costs regardless of the share ratio. That covers things like drainage tile maintenance, terracing, and irrigation equipment ownership. The tenant covers machinery, fuel, labor, and hauling. The division tracks who controls each asset: the landowner maintains the land, the tenant maintains the operation.
Gross Share vs. Net Share
How the split happens matters as much as the ratio. In a gross share arrangement, the crop is divided at harvest before any expenses are deducted. Each party then handles marketing and costs on their own portion. This is the simpler and more traditional approach.
In a net share arrangement, the crop is sold first, certain agreed-upon costs (drying, hauling, storage) are subtracted from total revenue, and the remaining proceeds are divided according to the share ratio. Net share deals require more bookkeeping but can feel fairer when post-harvest costs vary significantly from year to year. The lease should state clearly which method applies and list every cost that will be deducted before the split.
How It Compares to Cash Rent
Cash rent leases charge the tenant a fixed dollar amount per acre regardless of what the crop produces. Crop share ties both parties’ returns to actual production and market prices. The choice between them comes down to how much risk each side is willing to absorb and how involved the landowner wants to be.
- Cash rent puts all production and price risk on the tenant. Crop share spreads that risk. In a bad year, a cash rent tenant still owes the full rent; a crop share landowner takes a smaller check right alongside the farmer.
- Cash rent requires almost no landowner involvement beyond collecting a check. Crop share requires the landowner to make input cost decisions and potentially to market their share of the grain.
- Cash rent gives the landowner predictable income. Crop share income fluctuates with commodity markets and weather, which makes financial planning harder but can produce higher returns in strong years.
- Cash rent can tempt tenants to maximize short-term production at the expense of long-term soil health, since they capture all the upside. Crop share gives the landowner a direct financial stake in how the land is farmed.
Many landowners who inherit farmland start with crop share because it lets them learn the economics of their ground before committing to a fixed cash rent figure. Experienced landowners sometimes prefer crop share precisely because it keeps them connected to what’s happening on the farm.
What the Written Lease Should Cover
A lease longer than one year generally has to be in writing under the statute of frauds, and even a one-year arrangement is worth writing down. Shorter oral agreements are legally valid in most states, but a written document protects both sides when disagreements come up mid-season.
Start with a legal description of the property, which you can pull from the most recent deed or county property tax records. List the total acres, identify which fields are included, and note any acres excluded for conservation or other purposes. Then address:
- Term and renewal. Specify the start and end dates. Many farm leases run from March 1 through the last day of February to align with the crop year, though this varies by region. State whether the lease renews automatically if neither party gives notice, and set the deadline for that notice.
- Share ratio and crop types. List every crop the tenant may plant and the share percentage for each. Some leases use different ratios for different crops, such as one-third/two-thirds for corn but 50/50 for hay.
- Input cost allocation. Spell out who pays for fertilizer, seed, herbicide, insecticide, crop insurance premiums, drying, hauling, and storage. Don’t leave any category ambiguous.
- Government program payments. State how USDA payments such as ARC or PLC and crop insurance indemnities will be divided.
- Conservation requirements. Note any practices the tenant must follow, whether imposed by the landowner or required for USDA program eligibility.
- Marketing responsibility. Clarify whether the tenant markets the entire crop and remits the landowner’s share, or whether the landowner markets their own portion.
The USDA Farm Service Agency publishes a standardized crop-share-cash farm lease form (FSA-1940-51) that covers many of these elements and works as a starting template.1U.S. Department of Agriculture. Farm Service Agency – FSA-1940-51 Crop-Share-Cash Farm Lease University agricultural extension offices in most states also publish lease templates tailored to regional customs.
Notarization is not required to make a farm lease legally binding in most states; both signatures are enough. Recording the lease with the county is a separate question, and most recorder’s offices require notarized documents to accept a filing. Recording creates a public record of the tenant’s interest, which matters most if the landowner sells the property or takes on a new mortgage. A few states, including Iowa, actually require recording of agricultural leases above a certain duration.2Iowa Code. Iowa Code 558.44 – Mandatory Recordation of Conveyances and Leases of Agricultural Land Elsewhere, recording is optional but worth considering for leases longer than one year.
Tax Treatment for Landowners
How the IRS treats crop share income depends almost entirely on whether the landowner materially participates in the farming operation. This is the single most consequential tax question in a crop share arrangement, and getting it wrong can mean unexpected self-employment tax bills or missed Social Security credits.
When the Income Is Passive Rental
If the landowner does not materially participate in production decisions, the crop share is treated as rental income. The landowner reports it on IRS Form 4835 (Farm Rental Income and Expenses), and the net amount flows to Schedule E. This income is not subject to self-employment tax and does not count toward Social Security earnings credits.3Internal Revenue Service. Publication 225 (2025), Farmer’s Tax Guide
A landowner who simply collects their share of the grain check each fall, without making decisions about planting, fertilizer application, pest management, or marketing timing, falls into this category. Most absentee landowners who rely entirely on the tenant’s judgment are passive for tax purposes.
When the Income Is Self-Employment Income
If two conditions are both met, the crop share income loses its rental character and becomes self-employment income. First, the lease itself must provide that the landowner will materially participate in production or management of production. Second, the landowner must actually materially participate.4Office of the Law Revision Counsel. 26 USC 1402 – Definitions When both apply, the landowner reports the income on Schedule F, and the full net amount is subject to self-employment tax at 15.3 percent, which covers both Social Security and Medicare.5Internal Revenue Service. Instructions for Schedule F (Form 1040) (2025)
Material participation generally means the landowner is involved in decisions like what to plant, when to apply inputs, and how to market the crop. It can also include physical labor on the farm. Retired or disabled farmers who materially participated in at least five of the eight years before retirement can still qualify as materially participating, and a surviving spouse who actively manages the farm may qualify under special estate tax rules.5Internal Revenue Service. Instructions for Schedule F (Form 1040) (2025)
The SE tax bite is significant, but it comes with a tradeoff: SE income builds Social Security quarters and increases future benefit amounts. For landowners approaching retirement age, that can be a real planning consideration rather than simply a cost to avoid.
One detail that catches landowners off guard: hiring a farm manager to make decisions on your behalf does not satisfy the material participation requirement. The statute states that participation is determined “without regard to any activities of an agent.”4Office of the Law Revision Counsel. 26 USC 1402 – Definitions The IRS looks at what you personally did, not what your manager did.
Crop Insurance
Each party has an insurable interest in their portion of the crop. Either the landowner or the tenant can purchase a policy covering both shares, or each can hold a separate policy. However, federal crop insurance rules do not allow the same crop share to be covered under two different policies: if the landlord holds their own policy for a crop in a given county, the tenant’s policy cannot also insure the landlord’s share for that same crop and county.6USDA Risk Management Agency. Final Agency Determination FAD-122
When one party insures both shares under a single policy, the insuring party must provide evidence of the other’s approval, such as a copy of the lease or a power of attorney. The acreage report has to clearly state the percentage shares belonging to each person.6USDA Risk Management Agency. Final Agency Determination FAD-122
A practical complication arises when the tenant buys enterprise-level coverage that aggregates all of the tenant’s acres across a county. Indemnity payments under that structure are not tied to any single farm, which makes it difficult to allocate a payment back to one landowner’s ground. The lease should address this upfront by specifying whether the tenant carries insurance on the landowner’s share and how any indemnity proceeds will be divided.
USDA Programs and Conservation Compliance
Both the landowner and the tenant may be eligible for USDA programs including Agriculture Risk Coverage (ARC) and Price Loss Coverage (PLC), which make payments when crop revenue or prices fall below historical benchmarks.7Farm Service Agency. Agriculture Risk Coverage (ARC) and Price Loss Coverage (PLC) Many crop share leases split these payments in the same ratio as the crop, but the division is negotiable and should be written down.
To participate in most FSA and NRCS programs, both parties must certify on Form AD-1026 that they will not produce crops on highly erodible land without an approved conservation plan, plant on converted wetlands, or convert wetlands to cropland.8Farm Service Agency. Conservation Compliance A violation can disqualify both the landowner and the tenant from all covered programs, including crop insurance premium subsidies. The obligation extends to any “affiliated person” of the producer, so a landowner who farms other ground separately still has to maintain compliance across all operations.
Both parties also file annual crop acreage reports with FSA listing their respective share percentages for each crop.9USDA. Crop Acreage Reporting Information A landowner who lives far from the farm can grant the tenant authority to handle these filings using an FSA-211 Power of Attorney filed with the local FSA office.10USDA Farm Service Agency. Instructions for Completing an FSA-211 Power of Attorney for an Individual
Ending the Lease
A written lease with a fixed end date simply expires on that date unless it contains an automatic renewal clause. If the lease does include automatic renewal, both parties need to follow whatever notice deadline the lease specifies.
Oral crop share leases are presumed to renew automatically from year to year. To end an oral lease, the party who wants out must deliver written notice well before the lease year expires. Most states require at least four to six months’ advance notice for oral agricultural leases. A September 1 deadline for leases that renew on March 1 is a common benchmark, though the exact date varies by state.
Delivering termination notice by certified mail is worth the small extra cost. If a dispute arises about whether notice was given on time, a certified mail receipt is far more persuasive than a claim that you mentioned it over the fence. Keep a copy of the notice and the mailing receipt together in your lease file. Failing to give timely notice on an oral lease locks both parties into another full year, which catches landowners off guard most often after a landowner dies and the heirs want to change the arrangement.
What Happens When a Party Dies
The death of a landowner or tenant during the growing season raises immediate questions about who is entitled to the crop and whether the lease continues.
When a tenant dies, the doctrine of emblements protects the tenant’s estate. This longstanding legal principle gives the tenant’s heirs or estate the right to harvest any crop the tenant planted before death. The estate typically retains the tenant’s share of the harvest and remains responsible for the tenant’s share of input costs incurred during the season.
When a landowner who owns the property outright dies, the outcome is more straightforward. The heirs inherit the property along with the right to the landowner’s share of the growing crop. The lease generally continues through its stated term.
Complications arise when the landowner held something less than full ownership, such as a life estate. The authority to lease ends at death, and courts across the country are split on whether the deceased landowner’s estate or the person who inherits the property afterward is entitled to the landowner’s crop share. Landowners holding life estates should address crop share rights explicitly in both the lease and their estate planning documents. A single sentence in the lease clarifying what happens to the landowner’s share upon death can prevent litigation that costs more than the crop is worth.
