Home sale capital gains & seller net sheet calculators

Section 121 exclusion, gain or loss, taxable gain after depreciation, adjusted basis and an informal seller net sheet — federal educational worksheets inspired by IRS Publication 523. Nothing here concludes that you qualify.

Section 121 calculator Exclusion guide

Federal worksheets only. Calculators label a tax year you enter, ignore state tax unless you add an optional assumption, and never invent NIIT rules. Main-home losses are generally not deductible. Depreciation after May 6, 1997 is not excludable.

Frequently asked questions

Does SaleGain tell me I qualify for the Section 121 exclusion?

No. The calculators show worksheet-style results and eligibility checklists from the numbers you enter. They do not conclude that you qualify or that any exclusion is available on your return.

Are state taxes and NIIT included?

No. The tools are federal educational estimates. Optional state assumptions appear only when clearly labelled as user-entered. We do not invent NIIT or state tax rules.

Is this tax or real-estate advice?

No. SaleGain is an independent publisher, not a tax preparer, CPA, attorney, broker or the IRS. Confirm results with IRS Publication 523 and a qualified professional.
