After the $250K/$500K exclusion, here's what a typical seller might owe.
If Colorado is where your primary residence is located and you've lived there at least 2 of the last 5 years, you can exclude up to $250K (single) or $500K (married filing jointly) of your capital gain from both federal and state taxes.
Investment and rental properties in Colorado don't qualify for the exclusion. You'll owe 4.4% state tax plus federal tax on the full gain, plus 25% depreciation recapture on any depreciation claimed.
In Colorado, homes sold in May sell for 16% more than those sold in December (-20%). Timing your sale right can offset a significant portion of your tax bill.
