Do I have to pay capital gains tax when I sell my house in 2025?

Usually not. If it was your main home and you owned and lived in it 2 of the last 5 years, the first $250,000 of gain (single) or $500,000 (married filing jointly) is excluded under IRC §121. You only owe tax on gain above the exclusion. (Source: IRS Topic No. 701; Publication 523.)

Do I have to report the sale of my home?

You must report the sale if you receive a Form 1099-S or if any of your gain is taxable (above the exclusion). If your entire gain is excluded and you didn't get a 1099-S, you generally don't need to report it. Taxable sales go on Schedule D and Form 8949. (Source: IRS Topic No. 701.)

Does this calculate state capital gains tax?

No. This estimate is federal only. Most states tax capital gains as ordinary income and rates vary widely; a few (such as Florida, Texas, and Washington for ordinary gains) have no state income tax. Check your state's rules separately. (Source: IRS Topic No. 409, federal scope.)

Is my data sent anywhere when I use this calculator?

No. All calculations run entirely in your browser using JavaScript. No sale price, basis, income, or other inputs are ever transmitted to any server.
