Stepped-Up Basis on Farm Land — How Inherited Farmland Avoids Capital Gains Tax

The Single Most Valuable Tax Provision for Farm Heirs

A farmer who bought land in 1985 for $800 per acre is sitting on property worth $12,000 per acre today. If they sold it during their lifetime, the capital gains tax would apply to the entire $11,200 per acre of appreciation — potentially a six-figure or seven-figure tax bill on even a modest-sized operation.

But if that farmer holds the land until death, the heirs receive a stepped-up basis. The IRS resets the tax basis from the original $800 per acre to the fair market value on the date of death — $12,000 per acre. If the heirs then sell at $12,000, their taxable gain is zero. Decades of appreciation are wiped from the tax ledger in a single event.

This is not a loophole. It is an explicit provision of Internal Revenue Code Section 1014, and it applies automatically to most inherited property. For farm families, where land values have appreciated enormously over decades, the step-up in basis is often worth more than any other estate planning tool.

How Title Structure Affects the Step-Up

The size of the step-up depends entirely on how the property was titled before death:

Sole ownership (fee simple). The land receives a full 100% step-up to fair market value. This produces the best capital gains outcome for heirs.

Joint tenancy with right of survivorship (between spouses). In non-community property states, only 50% of the land receives a step-up. The surviving spouse's half retains its original basis.

Community property (between spouses). Both halves receive a step-up — the full 100% of the property's basis resets to fair market value when the first spouse dies, regardless of which spouse contributed the purchase price. This is why community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin) offer a significant advantage for married farm couples.

Tenancy in common. Only the decedent's fractional share receives a step-up. If three siblings own a farm as tenants in common and one dies, only that sibling's one-third interest is stepped up.

Joint tenancy with right of survivorship (non-spouse). The step-up applies only to the portion corresponding to the decedent's documented contribution to the original purchase. If a parent and child bought land together but only the parent paid, the IRS presumes the entire value is in the parent's estate — which actually produces a full step-up when the parent dies.

The Gift Trap That Costs Families Millions

When a living parent transfers farmland to a child as a gift, the child receives the parent's original cost basis — the "carryover basis." No step-up occurs. If the parent paid $800 per acre and gifts the land to their child, the child's basis is $800 per acre. A subsequent sale triggers capital gains tax on the entire appreciation.

This creates a direct conflict between estate tax planning and capital gains planning. Gifting farmland during life reduces the gross estate (potentially reducing estate tax), but it sacrifices the step-up in basis. Holding the land until death preserves the step-up but keeps the full value in the estate.

The math depends on the estate's size and available exclusion. The federal basic exclusion is $13.99 million per individual for 2025 deaths and $15 million per individual for 2026 deaths. A taxable estate below its available exclusion generally owes no federal estate tax — so gifting to reduce the estate may offer no benefit while sacrificing the step-up. For larger estates, the tradeoff requires careful calculation by a tax advisor who understands both sides.

Establishing the Date-of-Death Value

The stepped-up basis equals the property's fair market value on the date of death. For farmland, this requires a professional appraisal by someone qualified in agricultural real estate — ideally an Accredited Rural Appraiser (ARA) certified by the American Society of Farm Managers and Rural Appraisers.

The appraiser must consider soil productivity, drainage and tiling, water rights, conservation easements, wind or solar lease income, proximity to grain elevators, and comparable sales of agricultural land in the area. Development potential can inflate the value — and with it, the step-up — but the same inflated value also increases estate tax exposure if the estate exceeds the exemption threshold.

The executor can elect the alternate valuation date under Section 2032, generally six months after death, only if using it reduces both the gross estate value and the estate and generation-skipping transfer taxes. The election applies to the estate's property subject to the alternate-valuation rules, not just selected parcels; property distributed, sold, exchanged, or otherwise disposed of within six months is generally valued on its disposition date.

What Heirs Should Do After Inheriting

Get the appraisal done immediately. The date-of-death value is the basis, and documenting it with a contemporaneous professional appraisal is far more defensible than a retrospective estimate years later.

Do not assume you need to sell quickly. The stepped-up basis eliminates the historical capital gains — future appreciation from the date of death onward creates new taxable gain, but you are starting from a reset baseline.

If you plan to farm the land rather than sell it, the stepped-up basis still matters. It affects depreciation calculations for any improvements and establishes the baseline for future tax planning.

The Farm & Agricultural Estate Settlement Guide includes an asset valuation worksheet that walks through establishing the date-of-death basis for farmland, equipment, livestock, and stored grain — each of which follows different valuation rules.
