How Does Step-Up in Basis Work in Oregon?

Inherited assets in Oregon take a basis reset to fair market value on the date of death, and the gain on a later sale faces ordinary income tax at the state's regular rates.

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 Oregon 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 ordinary income tax at the state's regular rates. Oregon's top marginal income tax rate is 9.9%. 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 Oregon 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 Oregon

Step-up in basis is a federal rule that applies to inherited assets in every state, including Oregon. When someone dies, the cost basis of property they leave to heirs is reset to fair market value on the date of death. If the heir later sells, capital gains tax is calculated against this stepped-up basis instead of what the original owner paid. For appreciated assets held for years or decades, the step-up can eliminate most or all of the gain.

Oregon taxes long-term capital gains as ordinary income — there is no preferential capital gains rate. Any gain remaining after the step-up faces ordinary income tax at the state's regular rates. Oregon's top marginal income tax rate is 9.9%. The step-up is still valuable here: it reduces the gain on which both federal and state tax are calculated.

For Oregon families, the step-up in basis is one of the strongest tax reasons to inherit appreciated property rather than receive it as a gift during life, since a gift carries the donor's original basis. A Oregon revocable living trust preserves the step-up — assets held in the trust during life still receive the basis adjustment at death — while avoiding the probate process that a will alone triggers.
