With SCV home values where they are, many sellers worry about capital gains tax. This guide explains the basics — including the powerful primary-residence exclusion — in general terms.

Direct AnswerWhen you sell an SCV home for more than your adjusted cost basis, the gain may be subject to capital gains tax. But the federal primary-residence exclusion lets qualifying owners exclude up to $250,000 (single) or $500,000 (married filing jointly) of gain. California also taxes capital gains as ordinary income. This is general information, not tax advice — confirm with a CPA.

How gain is calculated

Gain is roughly your net sale price minus your adjusted cost basis (purchase price plus qualifying improvements and certain costs). Keep records of capital improvements — they raise your basis and can reduce taxable gain.

The primary-residence exclusion

The federal home-sale exclusion lets qualifying owners exclude up to $250,000 of gain (single) or $500,000 (married filing jointly) on the sale of a primary residence, subject to ownership and use tests. This federal threshold is stable enough to state, but eligibility is fact-specific.

California adds its own tax

California does not have a separate lower capital-gains rate — gains are generally taxed as ordinary income at California rates. Factor both federal and California treatment into your planning.

Investment property is different

The primary-residence exclusion does not apply to pure investment property. Investors often look at a 1031 exchange to defer gain instead.

Records win

The single best thing a seller can do is keep documentation of improvements and costs that adjust basis. Talk to your CPA well before listing.
