When you bought your farm ground, you bought the fertility in it. That residual soil fertility can be documented and depreciated — like tile or a barn. Safe Soil Tax builds the agronomy-backed report you and your CPA need, based on real sampling data. Online, in about 10 minutes.
*Your number depends on what you paid for the ground, nutrient levels when you bought it, and tillable acres. Run your own below.
Built on decades of university soil-fertility research — the same principles behind how fertilizer is actually applied today. Analytics customized by state.
Everything online. With soil data in hand, your report generates in about 10 minutes, with agronomist review within 1 business day. You can do it all online.
Real soil sampling, independent labs — and only bankable nutrients (no nitrogen or sulfur, which move). Where the tax treatment has grey zones, we quantify the risk and explain it in writing. Nothing hidden.
Location, acres, purchase date and price. Farmed ground bought up to 20 years ago qualifies easily; older can work too.
Lab soil data from within 4 years of purchase works. Don't have any? Order sampling right in the platform — we coordinate vetted sampling crews and vetted labs, and sampling can happen when crops aren't in the ground.
About 10 minutes with data in hand. If sampling wasn't done in the purchase season, we back-calculate nutrient levels to the time of purchase using crop modeling and your actual application rates.
Share the report directly, adjust results based on their input, and file with confidence. Grey zones are quantified and explained in writing so the two of you can make the call.
These are our recommendations for a strong, well-supported claim. Edge cases exist — when in doubt, start with a low-cost Estimate or ask us.
Not use-it-or-lose-it. Recent years can be handled by amending returns. Older purchases can often be captured through an accounting-method change (Form 3115) — your CPA reports the missed depreciation and catches it up, frequently taking most or all of it in the filing year. No fixed time limit applies to that path.
Buying the land is a new transaction: your basis equals what you paid, and the tax code does not reduce a buyer's basis for expenses deducted as a tenant. Same principle as a business that expenses leasehold improvements, later buys the building, and depreciates from its new cost basis. Document it well and confirm with your CPA.
Contributions to your own entity commonly carry the original basis and purchase date forward. If the fertility asset was never claimed, the catch-up route may still be available to the entity. Structure specifics are CPA territory.
Arm's-length family purchases at FMV generally work like any other purchase for the buyer. Certain corporate structures create seller-side tax wrinkles on the portion allocated to depreciable assets — worth a conversation before closing.
| Sampling Package | Estimate Only | Full Report |
|---|---|---|
| No Sampling | $13.00 | $33.00 |
| Sampling Required | ||
| Standard — 5 ac grid | $20.00 | $40.00 |
| Advanced — 2.5 ac grid | $23.00 | $43.00 |
Estimate Only tells you whether a full workup is worth it before you commit. Full Report is complete, agronomist-reviewed documentation for your CPA. Priced on tillable acres.
Why Advanced is recommended: for a few extra dollars, the 2.5-ac grid gives you industry-standard density data for full fertility management recommendations (not included in the report).
Illustrative math, not a promise or tax advice. Your values come from your soil; your rate comes from your CPA.
This is not a new idea, and it is not a loophole. The IRS framework asks a claimant to show three things: ownership of the fertility, its presence and extent, and that crops are actively exhausting it. Your report is built to establish all three. The authority behind the concept:
The IRS's foundational position: lime applied to farmland is an exhaustible capital expenditure that should be amortized over its period of effectiveness.
The IRS states that when a Section 180 election isn't made, fertilizer costs are chargeable to a capital account amortizable over the fertilizer's period of effectiveness — and that a taxpayer may amortize the capitalized cost of fertilizer applied to farmland. The denial in that ruling was fact-specific (no ownership, no quantification, no depletion evidence), not a rejection of the concept.
The IRS's own training material treats purchase-price allocation to residual fertilizer as an established practice, and lays out the exact three-part framework examiners look for. It was never superseded on soil fertility.
Defines qualifying materials broadly — fertilizer, lime, and other materials to enrich, neutralize, or condition land.
When you buy a farm, the price covers each identifiable asset at its fair market value — the same allocation logic used for tile, bins, and buildings supports separating residual soil fertility from bare land.
Your CPA picks the path. The report supports either.
Popular in recent years. Deduct in the current tax year; missed years by amended return, inside the ~3-year window.
Treats the fertility as a depreciating asset, like tile, and reaches back to the purchase. For older purchases: your CPA reports the missed depreciation and catches it up via a Section 481(a) adjustment — often taking most or all of it in the filing year. No fixed time limit. Depreciation method and period are your CPA's call.
Yes. The IRS has treated applied soil amendments as an depreciating asset since 1947, confirmed the treatment of capitalized fertilizer costs in a 1991 private letter ruling, and trains its own examiners on the framework. The concept isn't in question — the documentation is. That's what the report exists for. Full detail in the paper trail above.
Depends on what you paid for the ground, nutrient levels when you bought it, and tillable acres — often $600–1,200 per acre in deduction. Run the calculator above, or start with an Estimate Only report from $13/ac.
Usually not. Recent years can be amended; older purchases can often be captured through an accounting-method change (Form 3115) your CPA files, which catches up the missed depreciation — frequently most or all of it in the filing year.
Order sampling in the platform. We coordinate vetted sampling crews and vetted laboratories, and sampling can happen when crops aren't in the ground. If sampling postdates your purchase, we back-calculate to purchase-date levels using crop modeling and actual application rates.
No one can promise you'll never be examined. What we can tell you: the IRS's framework for this deduction asks for ownership, presence and extent of the fertility, and active exhaustion by cropping. Your report is built to establish all three with lab data and documented methodology, with any grey zones quantified in writing instead of hidden.
No. Safe Soil Tax is software that calculates and documents the deduction. We don't prepare or file returns, and nothing here is tax advice — your CPA applies the report to your situation.
