The Short Version
When farmland passes at death, the heir's cost basis generally resets to fair market value under IRC section 1014, and decades of built-in gain leave the ledger for income tax purposes. In California, farmland that is community property resets on both halves at the first spouse's death. Land gifted during life keeps the parents' old basis instead. Installment notes never step up. And for 2026, the federal estate exclusion is $15,000,000 per person, so for most families the income tax basis, not the estate tax, is where the planning money is.
A section of almonds bought in 1974, a home ranch assembled over two generations, a quarter of row-crop ground that has been in the family since before the canal district: the pattern across Kings, Tulare, and Fresno counties is low basis and high value. The gap between the two is the single largest number in most farm families' financial lives, and what happens to it depends less on markets than on sequencing. The rules below are why "who owns the land, how it is titled, and when it transfers" is a tax plan, not paperwork.
What basis is, and what death does to it
Cost basis is the number the tax code subtracts from your sale price to compute gain. Farmland held fifty years often carries a basis near what was paid fifty years ago, plus improvements, minus depreciation taken on trees, vines, irrigation systems, and structures over the decades. Sell during life at today's values and the difference is taxed, federal and Californian, with depreciation recapture layered on top; our $28M case study walks through what that stack looks like.
Death rewrites the number. Under Internal Revenue Code section 1014, property acquired from a decedent generally takes a basis equal to its fair market value on the date of death (or on the alternate valuation date six months later, if the estate qualifies for and elects it). Three consequences follow, each of them large for farm ground:
-
1
The built-in gain is gone. An heir who sells at the date-of-death value has little or no taxable gain. The appreciation from 1974 to now is never income-taxed to anyone.
-
2
Old depreciation stops mattering. The recapture that would have been triggered by a lifetime sale does not follow the land into the heir's hands; the new basis starts clean.
-
3
Depreciation can start again. Heirs who keep operating can allocate the stepped-up basis to depreciable assets, orchards, vines, irrigation, and depreciate them anew from the higher value, a real cash flow difference for a continuing operation.
The California advantage: community property
For married couples, how the land is characterized decides how much of it resets at the first death. California is a community property state, and IRC section 1014(b)(6) gives community property a distinctive result: at the first spouse's death, both halves of the property receive a new basis, the decedent's half and the survivor's half alike. The surviving spouse can sell, exchange, or re-depreciate from a full fair market value basis without waiting for the second death.
Property held in joint tenancy generally does not get that result: only the deceased spouse's half steps up, and the survivor keeps the old basis on their own half. The double step-up turns on the property being community property in character, which is a legal question and not simply a matter of what the deed says. Couples who assembled ground across decades, moved parcels in and out of title for financing, or came to California from a separate property state should have an estate attorney review characterization while both spouses are living. It is among the highest-value, lowest-drama fixes in farm estate planning.
The same section of ground, at the same value, on the same date, can carry two very different tax futures depending on whether the deed says "community property" or "joint tenants."
The gift trap
The instinct to "put the kids on the deed" runs strong, and it runs directly into IRC section 1015: property transferred by lifetime gift keeps the giver's basis. A gift of the ranch today hands the children the 1974 basis and everything that implies about a future sale. The same ranch passing at death would generally arrive with a fresh basis at fair market value. A gift can still be the right call for other reasons, and the property tax rules are their own analysis (see Prop 19 and the Family Farm), but a family should never sign a deed over without seeing the basis consequence in writing first.
What does not step up
A seller-financed note from a farmland sale is income in respect of a decedent, and IRC section 1014(c) carves it out of the step-up. Heirs collect the payments and report the deferred gain just as the seller would have. A family that sells on an installment contract late in life converts land that would have stepped up into a note that will not, one more reason the structure of a sale deserves as much attention as the price. We cover the other risks of carrying paper in When the Buyer of Your Farmland Defaults.
IRAs and other retirement accounts are also income in respect of a decedent; beneficiaries pay ordinary income tax as they draw them down. The step-up is a rule for property like land, not for tax-deferred accounts.
Large estates sometimes elect section 2032A special use valuation, which values qualifying farmland at its agricultural use value rather than its highest and best use, reducing the taxable estate by up to $1,460,000 for deaths in 2026. The tradeoff: the reduced value becomes the basis, and the family accepts a recapture period if the farm leaves qualified use. It is a genuine tool with real strings, and strictly a decision for the family's estate counsel and CPA.
Where the estate tax actually sits in 2026
For deaths in 2026, the federal basic exclusion amount is $15,000,000 per person (Rev. Proc. 2025-32), and with portability a married couple can generally shelter up to twice that. California imposes no state estate or inheritance tax. The practical effect for most Central Valley families: the estate tax is not the threat it was a generation ago, and the income tax basis has become the center of gravity in succession planning. Families above or near the exclusion, which a large operation with water and improvements can reach faster than its owners expect, need coordinated counsel well before a death, because the tools that help, 2032A among them, must be set up to be available.
What this means for the keep-or-sell decision
The step-up is why "just sell it now" and "just hold it forever" are both incomplete answers. A sale during life realizes the gain; a transfer at death may erase it; a gift preserves it in the children's hands; an installment note freezes it in a form that never resets. Which of those outcomes the family wants depends on health, timelines, who farms next, water, and what the proceeds would need to do, the same questions we work through in Keeping the Farm and The Cost of Waiting. The basis rules do not make the decision. They price it.

Common Questions
Stepped-Up Basis:
What Families Ask
Do heirs pay capital gains tax when they inherit?
No tax is due simply because farmland is inherited. The heir's basis generally resets to fair market value at death under IRC section 1014, and capital gains tax applies only if the heir later sells, measured from that new basis. Land held for decades can pass with its built-in gain effectively erased for income tax purposes.
What is the community property double step-up?
When one spouse dies, California farmland that is community property receives a new basis on both halves under IRC section 1014(b)(6), not just the deceased spouse's half. Joint tenancy property generally steps up only half. The result turns on the property's character, not just its title, and is worth an attorney's review while both spouses are living.
Does gifted farmland get a step-up?
No. A lifetime gift carries the giver's basis to the recipient under IRC section 1015. Putting the kids on the deed today hands them the original cost basis and the built-in gain; the same land passing at death would generally receive a fresh basis at fair market value.
Does an inherited installment note step up?
No. An installment note is income in respect of a decedent, excluded from the step-up by IRC section 1014(c). Heirs report the deferred gain as they collect, just as the original seller would have. Selling on a note late in life converts land that would have stepped up into an asset that will not.
Will the family owe estate tax?
Most families will not under current law. The 2026 federal basic exclusion is $15,000,000 per person, roughly double for a couple with portability, and California has no estate or inheritance tax. Larger estates have tools such as 2032A special use valuation, with real tradeoffs that belong in front of estate counsel early.
