How Does Step-Up in Basis Work in Alaska?

Inherited assets in Alaska take a basis reset to fair market value on the date of death, and the gain on a later sale faces no state capital gains tax.

When someone dies, the cost basis of the property they leave is reset to its fair market value on the date of death under IRC § 1014. A later sale is taxed on the gain above that stepped-up basis, not above what the original owner paid, so the appreciation of the owner's lifetime is never taxed. The rule is federal and applies in Alaska as in every state.

State capital gains tax is a separate layer from the federal tax. After the step-up, the gain on a later sale faces no state capital gains tax. The step-up still matters: it sets the gain on which both the federal and the state tax are figured.

For the capital gains tax, inheriting is usually better than receiving a lifetime gift. Inherited property takes a basis reset to fair market value at death under IRC § 1014; a gift carries the donor's original basis under IRC § 1015. Stock bought for $10,000 and worth $200,000 carries a $190,000 gain to the recipient of a gift and none to an heir. Property held in a revocable living trust still receives the step-up at the grantor's death.

No. Inherited property is treated as held long-term from the date of death under IRC § 1223(9), whatever the actual holding period, so a sale the day after the inheritance is taxed at the federal long-term rates of 0%, 15%, or 20% on any gain above the stepped-up basis, plus the Alaska layer. Short-term ordinary-income rates never apply.

The new basis is the fair market value on the date of death, and IRS Publication 551 sets the standard for each asset class: for a publicly traded security the average of the high and low prices that day, for real estate a qualified appraisal as of that date, for a privately held business interest an independent valuation (required where a federal estate tax return is filed). The valuation is what substantiates the basis on Schedule D when the heir sells.

Step-Up in Basis in Alaska

Under the federal step-up rule, the cost basis of inherited property is reset to fair market value on the date of death. Alaska residents inheriting appreciated stock, real estate, or business interests benefit from this the same way residents of every other state do — the rule is federal. State tax on any gain after the step-up is a separate, state-by-state question.

Alaska does not impose a state income tax or a separate capital gains tax: after the step-up, the gain on a later sale faces no state capital gains tax. Inherited assets sold by Alaska residents owe only federal capital gains tax on the post-step-up gain, at 0%, 15%, or 20% depending on total taxable income. This is one of the friendlier state environments for receiving and selling inherited appreciated property.

The step-up in basis is a federal benefit, but Alaska residents often combine it with state-specific planning to maximize the tax advantage. Holding appreciated assets in a Alaska revocable living trust preserves the step-up at death and keeps the assets out of probate, simplifying the transfer to heirs; a lifetime gift instead carries the donor's original basis.
