Date-of-Death Value and Stepped-Up Basis: Why the Business's Books Matter to the Heirs

When someone inherits a business, or a share of one, the tax that matters most is often not the one the estate settles now. It is the capital gains tax an heir could owe years later if they sell. What that future bill turns on is the property's basis, and for inherited property the basis is not what the founder originally paid. It is generally reset to the fair market value at the date of death. Publication 551 states that the basis of property inherited from a decedent is generally its fair market value at the date of the individual's death, a rule usually called a stepped-up basis. That single number, fixed at the moment the owner died, is the figure the heirs will measure a future sale against, and the business's own books are the evidence behind it.

Stepped-up basis, in plain terms

Basis is what you subtract from a sale price to figure your taxable gain. Buy something for $100,000, sell it later for $175,000, and your gain is $75,000. When you inherit property instead of buying it, the tax code hands you a new starting basis: the value at the date of death, rather than whatever the person who died had in it. So if a business was built from almost nothing and was worth $400,000 the day the owner died, an heir who inherits it generally starts with a $400,000 basis, not zero. Sell it a year later for $420,000 and the gain reported is measured against that stepped-up figure, not against the founder's original investment. This applies whether or not the estate is large enough to file a federal estate-tax return, because the step-up is a basis rule and does not depend on estate tax being owed.

The date-of-death value comes from the books

Fair market value at the date of death is an estimate someone actually has to make, and for an operating business it is not a number you read off a single page. An appraiser or CPA arrives at it by looking at what the business owned and owed and earned as of that date: the assets on the balance sheet, the equipment and inventory, the receivables, the debts, and the earnings history a buyer would price. All of that lives in the accounting records. The balance sheet as of the date of death, the fixed-asset and depreciation detail, the profit-and-loss history, and the general ledger behind them are the raw material a valuation is built from. Even when the estate hires a professional appraiser, the appraiser works from the financials. If the books are gone, the value has to be reconstructed from bank statements and memory, which is slower, weaker, and easier for an examiner to question later.

Why this reaches the heirs years later

The estate's own tax work happens close to the death: the decedent's final return for the year of death, and the estate's income-tax return if it earns enough while it is being settled. Those are the returns people think about first, and our guide for the executor handling a deceased owner's QuickBooks records walks through them. The date-of-death value is different because its consequence can be years away. An heir might hold the inherited business interest, or assets the decedent owned directly, for a decade before selling. When they do, the gain is generally measured against the basis set at the date of death, so the evidence for that basis has to survive the entire holding period. How that works for an ownership interest versus the entity's own assets, and how depreciation figures in, are questions for the estate's CPA. This is the same pattern that makes property records outlive a sale, where a disposal reopens the whole history of what an asset cost and what it was worth. Our post on depreciation recapture and the records a rental sale reaches back for covers that mechanic on the real-estate side, and the logic is identical for an inherited business. The moment that decides the basis and the moment the tax comes due can be separated by many years, and the records have to bridge them.

The evidence sits in QuickBooks, on a deletion clock

The timing problem is specific to a business whose books lived in QuickBooks Online. When the owner dies, the subscription keeps billing until someone stops it. Often nobody is thinking about the accounting software in the weeks after a death, so it either keeps charging a card that will eventually decline or gets cancelled to stop the payments. Either way, once the company is cancelled, the retention clock starts. Intuit holds a cancelled paid company in read-only mode for 12 months and then permanently deletes it; a company cancelled during a free trial gets only 90 days. There is no archive tier that keeps it longer, and once the company is deleted, resubscribing does not bring it back. So the balance sheet and asset detail that fix the date-of-death value, the very evidence the heirs will need if they sell years from now, can quietly expire about a year after the owner's death, long before anyone has thought about a future sale. Set that against how long the IRS expects business records to be kept: three years is the baseline, and it stretches to six when a return understates gross income by more than 25 percent, with property records running until the limitations period for the year the property is disposed of. The books need to last for years. The software keeps them for one.

Capturing the date-of-death snapshot before the clock runs

Because the value is fixed at a single date, the most useful thing anyone settling the estate can do for the heirs is capture the books as they stood, before the subscription lapses. That means the balance sheet as of the date of death, the fixed-asset and depreciation detail, and the profit-and-loss and general ledger for the periods a valuation would look at, in both cash and accrual basis, with the supporting documents still attached to their transactions. Kept together, that package is what an appraiser or CPA works from to set the value, and what the heirs can produce years later if a sale gets examined. How the valuation itself is done, and how any depreciation on inherited assets comes back into the math on a later sale, is the estate's CPA and appraiser's call. The records job is narrower: make sure the numbers still exist when they are needed. Our overview of how long to keep business records after closing covers the retention side once the file is safely out of the software.

Pulling all of that cleanly, in both bases, with every attachment still tied to its transaction and the totals checked against the live file, is real work, and it lands during a period when the family has more pressing things in front of them. If you would rather have it handled, that is the archive we build for you: one verified copy of the deceased owner's QuickBooks Online company, captured before the subscription is cancelled and delivered as a single download. The valuation date is usually fixed, and the records that support that value are much harder to rebuild later, so they are worth securing while the company is still open.
