When you inherit an SCV home, a tax rule called step-up in basis can dramatically reduce the capital gains you would owe if you sell. This guide explains the concept in general terms.

Direct AnswerUnder current federal rules, inherited property generally receives a step-up in basis to its fair market value as of the date of death. That means an heir who sells soon after often has little or no taxable gain, because the basis resets to the value at death rather than the original purchase price. This is separate from Prop 19 property-tax reassessment. This is general information, not tax advice — confirm with a CPA or estate attorney.

What step-up in basis means

Capital gain is sale price minus basis. For inherited property, the basis generally resets (steps up) to the fair market value on the date of death. Decades of appreciation on an SCV home can effectively disappear for capital-gains purposes if the heir sells near that value.

Why it matters in SCV

An SCV home held for many years may have a low original basis and large appreciation. Step-up can mean an heir selling shortly after inheritance owes little or no capital gains tax on the pre-death appreciation.

Step-up vs Prop 19

These are two different things. Step-up resets income-tax basis for capital gains. Prop 19 governs whether the low Prop 13 property-tax assessed value is preserved. An heir can get a step-up for capital gains and still face property-tax reassessment under Prop 19 if they do not occupy the home.

Timing of the sale

If the heir holds the home and it appreciates further, gain above the stepped-up basis can become taxable on a later sale. Document the date-of-death value with a qualified appraisal.

Frequently Asked Questions

What is step-up in basis?

It is the resetting of an inherited asset's tax basis to its fair market value at the date of death, which can sharply reduce capital gains tax if the heir sells near that value.

Will I owe capital gains tax on an inherited SCV home?

Often little or none if you sell soon after inheriting, because basis steps up to date-of-death value. Gain above that value on a later sale can be taxable. Confirm with a CPA.

Is step-up the same as Prop 19?

No. Step-up resets income-tax basis for capital gains. Prop 19 governs whether the low Prop 13 property-tax base is preserved. They are separate rules.

How do I document the stepped-up basis?

Obtain a qualified appraisal establishing the home's fair market value as of the date of death, and keep it with your records.

What if I keep the home for years?

Further appreciation above the stepped-up basis can be taxable when you eventually sell. Plan with a CPA.

Is this tax advice?

No, this is general education. Confirm your specific situation with a CPA and estate attorney.
