Sell an Inherited Stock the Day After You Get It and the IRS Still Treats the Gain as Long-Term
A retired nurse sold inherited shares the morning after they hit her account and braced for a steep tax bill at ordinary income rates. What her preparer told her next rewrites everything most people assume about holding periods and inherited…

A 61-year-old retired nurse lost her mother last winter. Her mother left a brokerage account holding a single blue-chip stock she had bought decades earlier for $40,000. When her mother died, the shares were worth $300,000.
Settling the estate took months. By the time the executor moved the shares into her own account, they had rose to $330,000. She sold the next morning and expected a short-term tax bill at her ordinary income rate, since she had owned the stock for a single day.
Her tax preparer corrected her. The $30,000 gain counts as long-term. The $260,000 the shares gained during her mother’s lifetime is never taxed at all.
Inherited Shares Skip the One-Year Clock
For most sales, the holding period determines the tax rate. The Internal Revenue Code defines a short-term capital gain as gain on an asset “held for not more than 1 year” and a long-term gain as one on an asset “held for more than 1 year”. Short-term gains are taxed at the same rates as wages.
Inherited property gets its own rule. Under Section 1223(9), when an heir’s basis is set under Section 1014, the heir “shall be considered to have held such property for more than 1 year.” IRS Publication 544 states it simply: an heir is “considered to have held the property longer than 1 year, regardless of how long you actually held it.”
The second half of the benefit is the basis reset. Section 1014(a)(1) sets the heir’s basis at “the fair market value of the property at the date of the decedent’s death,” or at the alternate valuation date if the executor makes that election under Section 2032. Publication 550 adds that gain or loss on an inherited capital asset “is considered long term, regardless of how long you held the property.”
One Day of Ownership Still Gets the 15% Rate
Assume she and her husband file jointly and fall in the 24% bracket. For 2025, that bracket covered joint taxable income from $206,701 to $394,600. Assume the entire gain remains inside that bracket.
- Date-of-death value (her new basis): $300,000
- Sale price: $330,000
- Taxable gain: $30,000
- Tax at the 15% long-term rate: $4,500
- Tax if the gain were short-term at 24%: $7,200
On its own, the holding-period rule saves her $2,700. The step-up saves far more, because it removes $260,000 of her mother’s lifetime appreciation from the tax base.
The rule covers losses too. If the shares had fallen below their value at inheritance before she sold, Publication 550 treats that loss as long-term as well.
A Lifetime Gift Would Have Cost $39,000 More
Two years before she died, the mother thought about giving her daughter the shares directly to keep things simple. That would have been expensive. Under Section 1015(a), the basis of gifted property “shall be the same as it would be in the hands of the donor,” so the daughter would have kept her mother’s $40,000 basis.
A sale at $330,000 would then have produced a $290,000 gain. At 15%, that comes to $43,500 of federal tax before any 20% bracket exposure or net investment income tax. That is $39,000 more than she paid by inheriting the shares.
One trap runs the other way. Section 1014(e) denies the step-up when appreciated property was given to the deceased during the 1-year period ending on the date of the decedent’s death and then passes back to the donor or the donor’s spouse. A child who moves low-basis stock to a dying parent, hoping to inherit it back with a fresh basis, gets the parent’s old basis instead.
Four Moves That Protect the Step-Up
- Get the date-of-death value in writing. Ask the executor or the brokerage for a valuation of every position as of the date of death. That number is your basis.
- Check your 1099-B before you file. Brokers often report inherited lots with no basis or label them short-term. Correct this on Form 8949 by reporting the sale as long-term with the inherited basis.
- Match the estate tax return. If the estate filed Form 706, Section 1014(f) generally limits your basis to the value finally determined for estate tax purposes. If the executor sent you a Schedule A (Form 8971), Publication 530 says you “may be required to report a basis consistent with the estate tax value.”
- Ask about alternate valuation early. If the executor chooses the Section 2032 date, that value replaces the original valuation for every heir.
A CPA or estate tax attorney can confirm how these rules apply to an estate that holds property in several states or in trusts (we put the full beneficiary, titling, and trust checklist in a free estate planning guide if you want a starting point).
Remember This One Number
Her number is $260,000: the lifetime gain the step-up eliminated. Selling one day after the shares landed in her account did nothing to change that, because the tax code had already treated her as a long-term holder.
