Part 1 of 4

Why a seller cares

Improvements add to your basis and lower the taxable gain, which is why the receipts for a roof, an addition or a kitchen matter at sale. Repairs do not count; the line between them is the tax code's, not yours.

Part 2 of 4

A simple example

Over twelve years you replaced the roof, added a deck and remodeled the kitchen for $48,000 total. Your basis rises by $48,000.

Capital improvement: a simple example
The spendingIs it a capital improvement?
A new roof, $14,000Yes; adds to basis
A kitchen remodel, $28,000Yes
Repainting and a furnace repairNo; repairs and upkeep

Improvements raise the basis. Keeping the receipts is what makes them count.

Part 3 of 4

What people get wrong

That everything spent on the house lowers the gain. Only improvements do; maintenance is the cost of living there.
