For homeowners
Don't let home improvements cost you extra
Track your home improvement projects to increase your home's cost basis, shrinking your taxable gain when you sell. Most people lose the savings because they lose the invoices. We keep them for you, organized and audit-ready.
How it works
You bought your home for $400k. Sold for $750k.
That's a $350,000 gain on paper — the number the IRS starts from.
Illustrative example. Actual savings depend on your income, filing status, and other factors. Not tax advice.

Your word isn't enough for the IRS, you need detailed record-keeping to benefit.

The tax break was set in 1997 — and never indexed.
You can exclude $250,000 of gain (single) or $500,000 (married) when you sell your main home. Congress set those caps in the Taxpayer Relief Act of 1997 and never tied them to inflation — so as home prices climbed, more and more sellers crossed the line.
The share of sellers whose gain could be exposed to capital-gains tax has climbed from roughly 3% when the caps were enacted to about half of home sales by 2025.
Indexed to home-price growth since 1998, the single and married caps would be about $720,000 and $1.44 million today — instead of the frozen $250,000 and $500,000.
