When you buy or inherit farmland, you could be gaining valuable nutrients already in the soil. The residual fertility deduction represents a specialized tax planning opportunity for both farmers and landowners. With the right approach, they can translate into meaningful economic benefits.
What is residual fertility, and why does it matter?
Residual fertility refers to plant‑available nutrients that remain in the soil at the time you acquire land. Because these nutrients are used up over future crop years, the IRS treats them more like a consumable asset than a permanent improvement to land. In practical terms, properly documented residual fertility can be deducted or depreciated, reducing taxable income while preserving your agronomic plans.
Applicable Tax Code Sections
Residual fertility deductions and depreciation are generally considered under three key sections of the Internal Revenue Code:
- Section 180 – Allows for the current deduction of certain soil and water conservation expenses, including fertilizer, by taxpayers engaged in farming.
- Section 167 – Provides for depreciation deductions on property used in a trade or business or held for the production of income.
- Section 168 – Establishes the rules for depreciating assets that last beyond one year, typically under Modified Accelerated Cost Recovery System (MACRS).
Documentation and Support Requirements
The IRS expects residual fertility deductions to be well-supported. The collaboration of Christianson and Anez Consulting pairs tax precision with agronomic rigor so you can move forward with confidence
