To avoid inheritance tax on a farm, most families rely on the $15 million federal estate tax exemption, and larger operations layer special-use valuation of farmland, portability between spouses, conservation easements, careful lifetime gifting, and installment payment elections to reduce or defer what’s owed. The federal exemption alone shields up to $15 million per person and $30 million for a married couple in 2026, which covers most family farms outright.1IRS. Rev. Proc. 2025-32 Operations valued above that, or farms in states with their own transfer taxes, need deliberate planning, and the biggest savings come from combining several strategies at once.
Start With the Federal Exemption
There’s no federal “inheritance tax” as such. What applies is the federal estate tax, calculated on everything a person owns at death before assets pass to heirs. Amounts above the exemption are taxed at up to 40%.2Office of the Law Revision Counsel. 26 USC 2001 – Imposition and Rate of Tax
The One Big Beautiful Bill Act permanently set the basic exclusion amount at $15 million per person for 2026, indexed for inflation in later years.1IRS. Rev. Proc. 2025-32 A married couple using portability can shield $30 million combined. A farm estate under that threshold owes zero federal estate tax with no special planning at all.
The harder question is what the estate is actually worth. Farmland is generally appraised at fair market value, which in many regions has been pushed higher by residential development pressure, energy leases, and land-price inflation. A 2,000-acre operation valued at $8,000 per acre is a $16 million estate before equipment, grain inventories, or livestock. That’s where the strategies below start to matter.
Special-Use Valuation for Farmland
Section 2032A lets an estate value qualifying farm real property based on its actual agricultural use rather than its highest-and-best-use fair market value.3Office of the Law Revision Counsel. 26 USC 2032A – Valuation of Certain Farm, Etc., Real Property Where cropland could theoretically be developed, the gap between farm-use value and market value can be very large. The maximum reduction under this election is $1,460,000 for 2026.
To qualify, the estate must meet each of these:
- At least 50% of the adjusted value of the gross estate must be farm real or personal property passing to a qualified heir.
- At least 25% of the adjusted value of the gross estate must be qualified farm real property specifically.
- The decedent or a family member must have owned and actively used the property for farming during at least five of the eight years before death.
- The decedent or a family member must have materially participated in the farming operation during that same five-of-eight-year window.
- The property must pass to a family member.
“Adjusted value” is the property’s value before the special-use discount, reduced by any mortgages or liens. Debt-heavy operations get less benefit, because the mortgage already reduces the net value in the estate.3Office of the Law Revision Counsel. 26 USC 2032A – Valuation of Certain Farm, Etc., Real Property
The 10-Year Recapture Rule
The savings come with a string attached. If the qualified heir sells the land to someone outside the family or stops farming it within 10 years of the decedent’s death, the IRS imposes an additional estate tax equal to the benefit the estate received from the reduced valuation.4Office of the Law Revision Counsel. 26 USC 2032A – Valuation of Certain Farm, Etc., Real Property – Section: Tax Treatment of Dispositions and Failures to Use for Qualified Use The heir is personally liable for that recapture tax, and it’s due six months after the sale or cessation of farming.
Renting to a non-family member can also trigger recapture. The cessation rules look at whether the property is still being farmed and whether a family member is materially participating. Cash-renting to a neighbor for passive income doesn’t meet that standard. An heir who wants to step back from active farming is safer leasing to another family member.
The Marital Deduction and Portability
When a farm passes to a surviving spouse, the unlimited marital deduction eliminates federal estate tax on that transfer. There’s no cap, and it applies regardless of size.5Office of the Law Revision Counsel. 26 USC 2056 – Bequests, Etc., to Surviving Spouse The exposure shifts to the second death, when the surviving spouse’s estate could exceed the exemption on its own.
Portability bridges that gap. When the first spouse dies, the executor files Form 706 to transfer any unused portion of that spouse’s $15 million exemption to the survivor. The return is due within nine months of death, with a six-month extension available.6IRS. Instructions for Form 706 If the family misses that deadline, a simplified late-filing procedure allows the portability election up to five years after the date of death.
The math is straightforward. If the first spouse used only $2 million of exemption, the survivor picks up the remaining $13 million and stacks it on their own $15 million, for a $28 million shield at the second death. For farms where one spouse holds most of the agricultural assets, filing Form 706 at the first death is one of the highest-value, lowest-effort steps in the whole process. Skipping it leaves money on the table that can never be recovered.
Stepped-Up Basis: Why Holding Until Death Often Wins
The step-up in basis is one of the most valuable benefits for farm heirs, and it shapes almost every other decision. When someone inherits property, the tax basis resets to fair market value at the date of death rather than what the original owner paid.7Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent If your parents bought farmland in 1975 for $500 an acre and it’s worth $8,000 an acre when you inherit it, your basis is $8,000. Sell the next day for $8,000 and you owe zero capital gains tax.
The step-up covers more than land. Fully depreciated equipment gets a new basis at current fair market value, and the heir can depreciate it again. Grain bins, barns, fencing, and drainage tile all reset the same way. To lock in the new values, everything needs to be appraised around the date of death. Skipping the appraisal is a common and costly mistake, because without documentation the IRS can challenge the stepped-up values years later.
This creates a tension with lifetime gifting, discussed next.
Lifetime Gifting
Giving farm assets away during your lifetime removes them from your taxable estate. The annual gift tax exclusion allows gifts of up to $19,000 per recipient in 2026 without using any lifetime exemption or filing a gift tax return.8IRS. Frequently Asked Questions on Gift Taxes A married couple can give $38,000 per recipient per year. Over a decade, gifting to three children moves $1.14 million out of the estate without touching the lifetime exemption at all.
For larger transfers, you can use part of your $15 million lifetime gift and estate tax exemption while alive.1IRS. Rev. Proc. 2025-32 Every dollar used for lifetime gifts reduces what’s available at death, but if the asset is expected to appreciate significantly, gifting freezes the value for transfer tax purposes. A parcel worth $500,000 today that grows to $800,000 by your death saves the estate tax on that $300,000 of growth.
The tradeoff is basis. Gifted property carries your original basis; inherited property gets the step-up. For farmland bought decades ago at a fraction of current value, the capital gains cost to the recipient can exceed the estate tax savings from the gift. For estates comfortably under the exemption threshold, holding property until death is almost always the better move.
Conservation Easements
Families who place a qualified conservation easement on farmland can exclude a portion of the land’s value from the taxable estate. Under Section 2031(c), the executor can elect to exclude up to 40% of the value of land subject to a qualifying easement, with a maximum exclusion of $500,000.9Office of the Law Revision Counsel. 26 USC 2031 – Definition of Gross Estate – Section: Estate Tax With Respect to Land Subject to a Qualified Conservation Easement
The full 40% rate applies only when the easement’s value is at least 30% of the land’s unrestricted value. Below that, the applicable percentage drops by 2 points for every percentage point under the 30% mark. An easement worth 20% of land value produces a 20% exclusion rather than 40%.
The catch is permanence. A conservation easement restricts development rights forever, so the family gives up the ability to subdivide or build. For families committed to keeping the property in agriculture, that isn’t much of a sacrifice, and the easement also lowers the fair market value of the land for general estate tax purposes. That reduction stacks on top of the 2031(c) exclusion and, where it applies, the 2032A special-use valuation.
Installment Payments When Tax Is Still Owed
Even with every deduction applied, some large farm estates will owe federal estate tax. Section 6166 is the lifeline: if the value of the farm or closely held business exceeds 35% of the adjusted gross estate, the executor can elect to pay the tax attributable to the farm interest in installments instead of a lump sum nine months after death.10Office of the Law Revision Counsel. 26 USC 6166 – Extension of Time for Payment of Estate Tax Where Estate Consists Largely of Interest in Closely Held Business
The estate can defer the first installment for up to five years after the normal due date, paying only interest during that stretch. After the deferral, the tax is paid in up to 10 equal annual installments, extending the total window to roughly 14 to 15 years from the date of death. The interest rate on a portion of the deferred tax is set at 2% under Section 6601(j), well below commercial rates, with interest on the remainder charged at 45% of the standard underpayment rate.
Farmhouses and buildings used by the owner or farm employees count toward the 35% threshold, which helps many operations qualify.11Office of the Law Revision Counsel. 26 USC 6166 – Extension of Time for Payment of Estate Tax Where Estate Consists Largely of Interest in Closely Held Business – Section: Farmhouses and Certain Other Structures Taken Into Account One major risk: if the heir sells 50% or more of the farm interest during the installment period, the remaining balance accelerates and becomes due immediately. Families planning to scale down gradually need to watch that threshold.
Family Limited Partnerships
A family limited partnership is a more aggressive tool. The family transfers farm assets into a partnership, with senior generation members as general partners and younger family members receiving limited partnership interests over time. Because limited interests lack management control and can’t be easily sold, they’re worth less than a proportionate share of the underlying assets. Appraisers typically apply discounts of 15% to 40% for lack of control and 10% to 30% for lack of marketability, depending on the specific restrictions in the partnership agreement.
For a farm worth $10 million, transferring a 20% limited interest with a combined 30% discount means the taxable value of that transfer is roughly $1.4 million instead of $2 million. Shifting limited interests to the next generation at discounted values can meaningfully shrink the taxable estate over time.
The IRS has challenged FLPs aggressively for decades. The partnership needs a legitimate business purpose beyond tax avoidance, and it needs to operate like a real business: separate bank accounts, formal partnership agreements, regular distributions, documented meetings. If the IRS finds that the senior generation retained too much control or kept using assets as personal property, it can pull those assets back into the estate under Section 2036 and erase the discounts. Families who lose these cases are usually the ones who set up the partnership on paper but changed nothing about how they actually ran the farm.
State Inheritance and Estate Taxes
Federal tax isn’t the whole picture. Five states impose a separate inheritance tax, where the rate depends on the heir’s relationship to the deceased rather than the size of the estate: Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania, with rates from 1% to 16%. Spouses and children are usually exempt or taxed at the lowest rates; distant relatives and unrelated heirs pay the most.
Roughly a dozen additional states impose their own estate tax with exemption thresholds well below the federal $15 million, some starting as low as $1 million. A farm estate that owes nothing federally can still face a significant state bill. State rules change often, so families in these states need to plan around their state’s current thresholds and rates in addition to the federal strategies.
How the Pieces Layer Together
These strategies aren’t alternatives. They stack. A well-planned farm estate might use the $15 million federal exemption as the foundation, add a special-use valuation election to reduce land value by up to $1,460,000, grant a conservation easement that excludes another $500,000, use portability to capture the first spouse’s unused exemption, and, if tax is still owed, stretch payments over 14 years at favorable interest rates. Meanwhile, the heirs benefit from stepped-up basis on everything they inherit, eliminating decades of embedded capital gains.
The coordination matters as much as the individual pieces. A will directing farm assets to the wrong beneficiary can disqualify the estate from special-use valuation. A lifetime gift of appreciated land can cost the family more in capital gains than it saves in estate tax. An FLP set up without proper formalities can invite an IRS challenge that wipes out the projected savings. Every piece has to fit the others, which almost always means working with an attorney and accountant who understand both agricultural operations and transfer tax planning.
