The Short Version
IRC Section 180 lets Texas agricultural landowners deduct the market value of excess soil nutrients present in the ground at the time of purchase or inheritance, typically $500 to $2,000 per acre, from their taxable income in the current year. The deduction requires certified soil analysis and IRS-formatted documentation. Soil Deduction Advisors handles the entire process from soil sampling to final report delivery.
The Law: What Section 180 Actually Says
IRC Section 180 states that a taxpayer engaged in the business of farming may elect to deduct expenditures for soil or water conservation, or for the prevention of erosion of land used in farming, paid or incurred during the taxable year. The IRS has interpreted this to include the value of excess soil nutrients present in the ground at the time of acquisition, since replacing those nutrients is a conservation expenditure. For a closer look at what counts as excess soil fertility, see our dedicated breakdown.
How the Dollar Value Is Calculated
We follow a strict protocol to collect soil samples, which a certified facility analyzes across a representative cross-section of your land. This includes nitrogen (N), phosphorus (P), potassium (K), and other macro- and micronutrients, giving a complete picture for the deduction.
​
For properties purchased in years prior to the one being evaluated, SDA then applies a sophisticated set of calculations, factoring in a baseline, and depletion rates based on the crops or vegetation demands, along with any fertilizer applications that may have been made after the purchase to establish a nutrient level basis at the time the property was acquired or inherited.
Â
The result is a defensible dollar figure that represents the value of the excess nutrients at the time of acquisition. For more on how we measure and document this soil nutrient load, see our detailed explainer.
What Documentation the IRS Requires
To claim Section 180, you need:
​
-
Certified soil analysis from an accredited laboratory
-
Nutrient depletion calculations tied to your specific land and use history
-
Nutrient valuation using relevant regional commodity pricing
-
A report formatted to IRS standards that your CPA can attach to your return

How It Reduces Your Tax Bill
Section 180 is an above-the-line deduction that reduces your adjusted gross income. Unlike a tax credit (which reduces tax owed dollar-for-dollar), a deduction reduces the income that is taxed. At a 37% federal marginal rate, a $500,000 Section 180 deduction saves approximately $185,000 in federal income tax. State tax savings are additional.

Frequently Asked Questions
Texas-based soil nutrient documentation specialists helping agricultural landowners unlock Section 180 tax deductions with CPA-ready reporting built to IRS standards.
No. Bonus depreciation and cost segregation apply to real property improvements and equipment. Section 180 is specific to soil and water conservation on agricultural land. They are separate strategies, some landowners use both.
Yes, you can, but we advise you consult with your CPA to determine the best strategy for your situation. Deductions can often be stacked, applied to future income, or offset other sources of income.
A standard soil test only tells you what nutrients are in your soil. Soil Deduction Advisors goes further: we provide an independent evaluation of the value of those nutrients based on the time of purchase using sophisticated calculations and formal chain-of-custody sample handling procedures, and produce a detailed report meeting IRS standards, ready for your CPA to use. A raw lab report alone is not sufficient for a Section 180 claim. The IRS wants to know that the value being claimed was not a best guess provided by the landowner. Your CPA and the IRS will want to know that you have a well-reasoned, documented report from SDA.
No. The basic process is the same; however, depending on when land was purchased or inherited, more documentation may be needed on the farmland, especially if multiple crops or fertilizer applications have been made since it was acquired. The reports from SDA will provide the documentation necessary regardless of what type of agricultural land you have.
Our reports are designed to be audit-defensible. Every deliverable includes accredited lab certifications, chain-of-custody documentation, nutrient valuation methodology, and supporting calculations. We stand behind our work and can provide additional documentation if needed.
