When you buy or inherit farmland, part of what you paid for is the unexhausted fertilizer left in the ground, phosphorus, potassium, and lime above what a normal crop uses. Section 180 lets you deduct that residual fertility as it’s consumed. On productive ground, it’s often a large first-year deduction.
See If Your Land QualifiesThe tax code treats land as non-depreciable, you can’t write off the dirt. But the unexhausted fertilizer a prior owner applied and left behind is different: it’s a consumable input that depletes as you farm. Under IRC §180, a taxpayer in the business of farming can elect to deduct the value of that residual fertility in the year the land is acquired, much like fertilizer they applied themselves. It’s a deduction, a change in when you write off part of the purchase, and on well-managed ground it can be substantial.
The deduction is narrower than the promoters suggest, and getting the boundaries right is the whole game.
The deduction has to be supported by parcel-specific soil tests, taken in the year of purchase, after closing and before any new fertilizer goes on. Area-wide fertility data doesn’t meet the bar, and neither does a rule of thumb. The number comes from the samples, tied to the specific ground you bought, showing fertility above a normal baseline. Miss that window, and the strongest evidence is gone.
This deduction is legitimate, but it’s been pushed too far. Some firms now claim the value of all soil nutrients, or apply it to land bought long ago, positions that lack clear legal support and are drawing IRS scrutiny and penalty exposure. We do it the careful way: unexhausted fertilizer only, above a real baseline, valued off parcel-specific tests, and documented to hold up. A conservative deduction you keep beats an aggressive one you defend.
Section 180 is a deduction for the residual fertilizer in farmland you bought. The R&D credit is a credit for the experimentation you do to farm better, new methods, equipment, or inputs. They’re separate incentives, and many operations qualify for both.
This page is general information, not tax or legal advice. The residual fertility deduction under Section 180 is fact-specific and rests on limited authority; it requires parcel-specific soil testing, and aggressive or unsupported claims carry audit risk. Eligibility and amounts are determined through the soil study in coordination with your tax advisor. Novaric does not guarantee deduction amounts or any IRS outcome.
