What Is Fair Market Value for Step-Up Purposes—and Who Decides It?

When a farmer dies, the value assigned to land, machinery, livestock, and other property can shape the family’s income-tax bill for years. For many farm families, the federal estate tax is not the main concern. The larger succession threat may be income tax—especially when heirs sell an asset with a low tax basis or continue depreciating property whose basis was not properly established.

The starting point is usually fair market value on the date of death. That value can become the inherited property’s income-tax basis, often called a “step-up in basis.” But it is not a number the family can simply pick. The executor or personal representative is responsible for reporting values, usually with help from qualified appraisers, and the IRS can challenge a valuation it considers unsupported.

Before discussing a strategy, I ask: Who is likely to sell this asset, and when? A valuation that works for a family keeping ground for generations may create a different result for heirs who plan to sell equipment, divide land, or wind down the operation.

What Does Fair Market Value Mean?

For federal tax purposes, fair market value generally means the price property would change hands for between a willing buyer and a willing seller, neither under pressure to act, and both having reasonable knowledge of the relevant facts. For a step-up basis valuation, the key date is typically the decedent’s date of death.

That does not mean “what the family thinks it is worth,” the amount shown on an old balance sheet, or the value someone paid years ago. It means an estimate of the property’s market value on a particular date, supported by relevant evidence. The evidence might include comparable sales, market data, property condition, legal restrictions, and the asset’s specific characteristics.

Some estates may elect an alternate valuation date six months after death. That election has strict requirements, including that it reduce both the gross estate and the estate tax due. It is not a general-purpose way to choose whichever valuation date produces the best income-tax result. Ask a tax professional to check whether it is available and whether it fits the estate.

Why Step-Up Basis Matters More Than Many Families Expect

Basis is generally the tax investment assigned to an asset. It matters when calculating gain or loss on a sale and, for depreciable property, helps determine future depreciation deductions. In many cases, inherited property receives a basis equal to its fair market value on the date of death—or the value determined under a valid alternate valuation election. Special rules and exceptions can apply, so the result depends on the asset and how it was owned.

A higher inherited basis can reduce taxable gain if an heir sells. It can also establish a new starting point for depreciation when inherited property is used in a business. That is why a careful farm appraisal for estate planning can matter even when estate tax is unlikely.

Many farmers track cash income and expenses through Schedule F, but a Schedule F is not an appraisal. It does not establish the date-of-death value of inherited land or equipment. Nor does it necessarily show the full tax story behind an asset. Families should keep the tax return, depreciation schedules, purchase records, and valuation reports together.

Depreciation, Equipment, and the Recapture Question

Depreciation lowers an asset’s adjusted basis as deductions are claimed. That can be useful during the operator’s lifetime, but it can leave a large gap between an asset’s market value and its tax basis. If the asset is sold during the owner’s lifetime, the gain may be taxable.

For equipment, one important rule is IRC Section 1245. When qualifying personal property is sold for more than its adjusted basis, some or all of the gain may be treated as ordinary income to the extent of depreciation allowed or allowable under the applicable rules. Ordinary income treatment can be less favorable than long-term capital-gain treatment. That is the depreciation recapture risk people mean when they talk about “paid-off” equipment: having no loan does not mean the tax basis is high.

But heirs should not assume they automatically inherit the decedent’s entire accumulated recapture bill. In a typical inheritance that qualifies for a basis adjustment, the new basis is generally determined under the inherited-property rules. If the heir later sells the equipment, tax treatment depends on the heir’s basis, post-inheritance depreciation, sale price, and the detailed Section 1245 rules. A sale near the properly established date-of-death value may produce little or no gain; a later sale above adjusted basis can produce taxable gain and potentially ordinary income recapture.

That is why the words “estate tax” can scare farmers for no reason, while an unsupported value or missing depreciation schedule should scare them more. Get the starting basis right, document depreciation after inheritance, and model a likely sale before signing a bill of sale.

Which Farm Assets Need Valuation?

A farm appraisal for estate purposes may cover more than the home place. The estate team should farm tax planning pricing identify the property, ownership, and likely use or sale plans for each major asset. Depending on the operation, that can include:

Land and buildings: Tillable acres, pasture, timber, homes, grain bins, barns, and other improvements may need separate analysis.
Machinery and equipment: Condition, age, hours, make, model, and local market activity can affect value.
Livestock and stored commodities: Type, quantity, condition, and market prices on the valuation date matter.
Farm entities: An interest in a partnership, LLC, or corporation may require valuation of the interest itself, with attention to ownership rights and restrictions.
Leases, contracts, and other rights: These can affect what a buyer would pay for an asset or ownership interest.

Market reports can help provide context, but they do not replace asset-specific analysis. For example, USDA Economic Research Service data can inform a broader understanding of agricultural markets and farm economics. AGDAILY may offer useful agricultural reporting and market context. Neither source, by itself, determines the fair market value of a particular family’s parcel or combine on a particular date.

Who Decides the Value?

The executor or personal representative is generally responsible for gathering information and reporting estate values when required. That person does not have to personally appraise every asset. The practical approach is to use professionals with relevant experience, preserve their work, and coordinate the results with the estate’s tax preparer and attorney.

Appraisers provide evidence

Real estate, machinery, livestock, business interests, and specialized assets may call for different expertise. A qualified appraiser should understand the asset type and the valuation date, explain the methods used, and support the conclusion with records and market evidence. For land, for example, the appraiser may consider comparable sales, soil and access, improvements, zoning, leases, and other facts that influence what a buyer would pay.

The executor reports; the IRS may review

The appraisal is evidence, not a guarantee that the IRS will agree. The executor or preparer uses the evidence to determine what to report on the relevant tax filings. If the IRS examines the return, it may ask for documentation or assert a different value. A defensible report is more useful than a bare number on a spreadsheet.

Keep copies of appraisals, photographs, equipment lists, title and ownership documents, comparable sales, invoices, and depreciation schedules. Note the valuation date and make sure the report describes the asset as it existed on that date—not after repairs, later market shifts, or a subsequent sale.

Common Valuation Mistakes to Avoid

Using tax assessed value as if it were market value. Property-tax assessments may follow different rules and dates.
Relying on an old balance sheet. Historical cost and book value do not establish current fair market value.
Valuing a whole farm when ownership is divided. The interest being transferred and its rights may matter.
Ignoring depreciation records. Basis and future gain cannot be analyzed reliably without them.
Assuming a step-up solves every tax problem. It does not make every sale tax-free, and it does not replace a succession plan.

Who Is Likely to Sell This Asset—and When?

That question should guide the planning conversation. If heirs expect to keep land and rent it, the basis may affect future depreciation and a later sale. If they expect to sell equipment promptly, a reliable date-of-death value can help establish the tax starting point. If one heir will buy out another, the family needs to distinguish a fair buyout price from the tax basis used for income-tax purposes.

Asset or decision Why value and basis matter Useful records or support Farm ground Inherited basis can affect gain on a later sale Real-estate appraisal, comparable sales, ownership records Machinery Basis affects depreciation and potential Section 1245 treatment on sale Equipment appraisal, condition details, depreciation schedules Farm business interest The value of the ownership interest may differ from a simple share of asset values Entity agreements, financial statements, valuation analysis

Build a sale timeline into the plan. Selling immediately, operating the farm for several years, and transferring property to another family member can lead to different tax outcomes. The preparer should review the relevant basis and depreciation details before a sale or transfer, not after the transaction is complete.

Make the Valuation Usable for the Next Generation

A strong valuation is dated, specific, and supported. It should identify what was valued, explain the methods and evidence, and be consistent with the estate’s reporting. Coordinate the appraisal with the tax preparer so the resulting basis is recorded correctly in the heirs’ files and in the books of any farm business.

Families can also make the work easier by organizing records before a death: current equipment lists, ownership documents, entity agreements, land leases, and depreciation schedules. An educational tool can help relatives get familiar with unfamiliar terms. For example, an heir might use the Instaread audio player to listen to an Instaread summary while reviewing the family’s planning materials—but an audio summary is no substitute for tax advice or an appraisal.

Fair market value for step-up purposes is generally a date-specific estimate of what a willing buyer and seller would agree to under ordinary conditions. The executor is responsible for reporting the value, appraisers help support it, and the IRS can challenge it. For farm families, the point is not just to minimize estate tax. It is to establish a defensible basis, understand depreciation and potential Section 1245 recapture, and decide who may sell each asset—and when.
