For farmers and ranchers who use the cash method of accounting, strategically prepaying expenses can unlock valuable tax benefits. When used correctly, prepaid supplies and rent allow producers to manage taxable income and smooth out financial swings between years. But without proper planning and documentation, these strategies can draw unwanted IRS attention and potential penalties. In this article, we’ll explain how prepaid farm supplies work, the IRS’s 50% rule, when prepaid rent is deductible, and best practices for managing prepaid expenses safely.
Prepaid supplies are items such as seed, feed, fertilizer, and chemicals that are paid for before year-end but used in the following year. These costs are deductible in the year they are paid—as long as they meet certain IRS conditions:
However, the IRS places limits on how much of these expenses can be deducted in a single year.
In most cases, the IRS limits prepaid farm supply deductions to 50% of other deductible farm expenses for the year (excluding the prepaids themselves).
Example:
If a farmer’s other deductible expenses total $100,000, the maximum prepaid supply deduction allowed is $50,000 (50% of $100,000).
Exceptions may apply when there are major operational changes—such as a significant expansion, disaster, or other extraordinary circumstances—or if your three-year average of prepayments is below 50% of other deductible expenses.
A farm-related taxpayer is defined as someone whose main residence is on a farm, whose principal occupation is farming, or who is a family member of such a taxpayer. This definition may also extend to corporations primarily engaged in farming activities.
Farmers and ranchers on the cash basis can also prepay up to one year’s rent for land, buildings, or equipment and deduct the expense in the year it’s paid—as long as it covers 12 months or less and is not simply a deposit.
Unlike prepaid supplies, prepaid rent is not subject to the 50% limitation. However, only the business-use portion of rent qualifies; any personal or residential portion must be excluded.
The cash method of accounting allows farmers to deduct expenses when they’re paid and report income when it’s received—not when earned or incurred. This offers several key benefits:
By strategically timing payments near year-end, cash-basis farmers can actively manage their taxable income and improve year-to-year financial stability.
In addition to thoughtful prepayments, you’ll want a robust farm budget to guide your decisions. See our Farm Budgeting 101: Getting Started article for tools and tactics to build a more resilient farm budget.
While prepaid deductions are valuable, excessive or poorly documented use can backfire. The IRS scrutinizes prepayments closely and may deny deductions if:
Large prepayments can also strain cash flow and create tax complications if conditions change unexpectedly. Overly aggressive prepayments may stress your capital position or reduce flexibility for debt service.

To maximize benefits and minimize audit risk, farmers should:
