Your cost basis includes the original purchase price plus certain costs: broker commissions, transfer fees, and for real estate, closing costs and capital improvements (not repairs or maintenance).

Primary Residence Exclusion

When selling your primary home, you can exclude up to $250,000 of gain ($500,000 for married couples filing jointly) if you owned and lived in the home for at least 2 of the 5 years before the sale. Gains above this exclusion are taxable.

Reporting & Payment

Report capital gains on Schedule D of your federal tax return. You may need to make estimated tax payments if you expect to owe $1,000 or more in taxes for the year.
