Farm Entity and Estimated Taxes: Schedule F or the S Election, the Land in Its Own LLC, and the March 1 Rule That Replaces Four Payments

Most farms are sole proprietorships on Schedule F, and for many that is right: the cash method, income averaging, and the farmer's estimated tax rule all work without an entity. The decision to add one turns on three things — liability from equipment, livestock, and workers; the self-employment tax on a profitable operation; and the land, which often belongs in its own entity regardless of how the operation is structured.

The entity choices

A sole proprietorship or single-member LLC reports on Schedule F, pays self-employment tax on net farm profit, and keeps every farm election available. A partnership or multi-member LLC — common where siblings farm together — files Form 1065 and passes Schedule F income through on Schedules K-1, with each general partner paying self-employment tax on their share (limited partners generally do not, apart from guaranteed payments). An S corporation pays the farmer a salary and distributes the rest without self-employment tax; it retains the cash method and depreciation benefits, and income averaging survives: Schedule J is elected by the individual shareholder, both for pass-through farm income and for compensation paid by the corporation in the conduct of its farming business. A C corporation is rarely right for a working farm: double tax on distributions, and appreciated land inside it is trapped.

The S election pays when the farm's profit comfortably exceeds a reasonable salary for the farmer's labor, year after year. Farms with volatile profit — a drought year following a record year — gain less, because salary must be paid in the bad year too.

The land belongs in its own LLC

Farmland appreciates, carries liability from what happens on it, and is the asset the family wants to keep when the operation changes hands. Holding it in a separate LLC that leases it to the operating entity isolates it from operating liabilities, lets the next generation take over the operation without buying the land, and keeps the land out of any corporation. The rent paid by the operation is deductible; the rent received by the land LLC is not subject to self-employment tax unless the rental arrangement provides that the owner will, and does, materially participate in the production or management of production on the land. The self-rental rule treats net rental income as non-passive when the owner materially participates in the operation. At the owner's death, land held personally or in a disregarded LLC receives a stepped-up basis, and farmland may qualify for special use valuation for estate tax, which values it at farm use rather than development value (the reduction is capped at $1,460,000 for 2026 deaths).

The farmer's estimated tax rule

A taxpayer whose gross income from farming is at least two-thirds of total gross income (this year or last) has two options instead of four quarterly payments: make one estimated payment by January 15 equal to the lesser of two-thirds of this year's tax or 100 percent of last year's, or skip estimates entirely and file the return and pay the full balance by March 1 (March 2, 2026 for 2025 returns, because March 1 fell on a Sunday; March 1, 2027 for 2026 returns). The 110 percent prior-year rule for higher incomes does not apply to qualifying farmers. The March 1 route is the common one — it costs nothing in penalty and keeps cash on the farm through the winter. Farmers with substantial off-farm wages or a spouse's salary may fail the two-thirds test and fall back to the normal four payments or annualization.

Income averaging and the entity

Schedule J applies to "elected farm income" — Schedule F profit and gains on farm assets other than land — reported by an individual, including farm income passed through from a partnership or S corporation. A farmer who elects S status and takes part of the profit as salary does not lose averaging on it: a shareholder may treat compensation paid by the S corporation in the conduct of its farming business as farm income, so the S election analysis turns on payroll tax and cash flow rather than Schedule J.

Payroll, workers, and the H-2A season

Farms with employees run payroll like any employer, with two differences: agricultural wages are subject to Social Security and Medicare only once the farm pays a worker $150 or more in cash wages for the year or pays $2,500 or more in total to all farmworkers (the $150 and $2,500 tests in Publication 15 (2026), which absorbed the discontinued Publication 51), and are reported on Form 943 annually rather than Form 941 quarterly. Seasonal workers under the H-2A program are exempt from Social Security and Medicare, but their pay is reported in box 1 of Form W-2 (not as Social Security or Medicare wages) once it reaches $2,000 for the year (2026; $600 for 2025), and income tax is withheld only if the worker asks and the employer agrees. Children of the farmer under 18 working for a parent's sole proprietorship, or for a partnership in which each partner is a parent, are exempt from those taxes entirely — an exemption lost if the operation becomes an S corporation.

Passing the farm on

Gifts of land during life carry the farmer's low basis; land held until death steps up. With the estate exemption at $15 million per person for 2026, most farms face no federal estate tax, so the step-up usually dominates, and the planning question is control: an LLC with non-voting interests gifted over time and voting interests retained, a buy-sell among the children, and a lease between the land LLC and whichever child runs the operation. Special use valuation and the installment payment of estate tax for closely held businesses remain available for larger estates.

Worked example. A family farm nets $320,000 of Schedule F profit after a strong year, with $600,000 of land held in a separate LLC that charges the operation $30,000 of rent. Farm income is more than two-thirds of the family's gross income, so no estimated payments are made; the return is filed and paid by March 1. Schedule J spreads the profit across the three prior years' lower brackets. The farmer weighs an S election for the operating entity: a $90,000 reasonable salary would remove employment tax from the remaining $230,000 ($320,000 − $90,000, before the employer's share of payroll tax on the salary); the salary itself can still be averaged on Schedule J as compensation from a farming S corporation, but it must be paid in the next drought year too, and any of the farmer's children under 18 on the payroll would lose their Social Security and Medicare exemption. The land stays in its LLC either way.
