Does California give long-term gains a lower tax rate?
California taxes capital gains as ordinary income; it does not have a lower state rate for long-term gains. A favorable federal capital-gain rate is not a California rate. The taxable gain is also different from the total sale proceeds.
FTB directs filers to California Schedule D (540) when federal and state capital-gain treatment differs. Reconcile state basis and carryovers rather than assuming the federal result can always be copied.
- Check the state’s actual treatment
- Identify the seller, income type and residence before choosing a return or assuming an exemption. Read the state guidance
Selling after a move or selling San Jose property
California taxes worldwide income during California residence and California-source income during nonresidence. A San Jose property sale can remain a California-source issue after you move away. A brokerage’s address does not settle your residence.
FTB Publication 1100 illustrates separate resident and nonresident capital-loss carryover calculations. Give the preparer move dates, earlier state schedules and carryover records; a change of address alone is not a tax computation.
- Review the separate filing or transaction route
- Bring the sale agreement and ownership details to the preparer or closing professional. Open the official guidance
- Match income to the residence period
- California real-property source rules can continue after a move. Read California residence guidance
Home sales and inherited property need different records
A federal main-home exclusion has ownership, use and other conditions. Receiving Form 1099-S can require reporting even when the gain is excludable. Selling a rental, second home or inherited home is not automatically the same transaction.
For inherited property, keep estate valuations and ownership evidence. Receiving an inheritance and selling it later are separate events; the original owner’s purchase price is not automatically your basis.
- Check the federal home-sale rules
- Ask whether the exclusion and sale-reporting requirements both apply. Read IRS home-sale guidance
What to bring to a tax preparer
- Purchase and sale dates, gross proceeds, selling expenses and adjusted-basis support.
- Brokerage forms, closing statements, improvement records and estate valuations where relevant.
- Move dates, earlier federal/state schedules, loss carryovers and any tax paid at closing.
- Reconcile gain rather than taxing proceeds
- Use the IRS basis and capital-gain reporting guidance alongside the state instructions. Read federal capital-gain guidance
- Check payments during the sale year
- An investment gain can require estimated payments even without wage withholding. Review federal estimated-tax requirements

Ask a professional about your situation
Ask whether the practice handles this tax, transaction, location and year. Agree in writing who checks the records, prepares each return and handles any notice. General listings do not verify specialist expertise or eligibility.
Compare professional qualifications and questions to ask. Keep personal tax documents private; this directory does not receive returns, identity documents or portal credentials.
