Taxes When You Sell Your House for Cash in Colorado

'Cash sale' doesn't mean a different tax

Selling for cash simply means the buyer isn't using mortgage financing — it speeds up closing and removes financing risk, but it doesn't create a special 'cash tax.' Your tax situation is driven entirely by your capital gain: roughly the sale price minus your cost basis minus selling costs. Whether the buyer wires cash or brings a loan to closing, the gain calculation is identical.

How to figure your gain (and your basis)

Your basis usually starts with what you paid for the home, plus the cost of major improvements over the years (a new roof, an addition, a renovated kitchen — not routine repairs). Your gain is the sale price minus that basis, minus selling costs. So a house bought for $250,000 with $50,000 of improvements has a basis around $300,000; sold for $400,000, the gain before any exclusion is roughly $100,000.

For inherited homes, the basis is generally 'stepped up' to the home's value on the date the previous owner died — which is why heirs who sell soon after often have little or no taxable gain.

The home-sale exclusion that wipes out tax for many sellers

If the home was your primary residence for at least 2 of the last 5 years, the federal home-sale exclusion lets you exclude up to $250,000 of gain if you're single, or up to $500,000 if you're married filing jointly. For most ordinary home sales, that exclusion erases the entire gain — meaning you owe no capital gains tax at all. In the example above, a $100,000 gain on a primary residence would typically be fully excluded.

The exclusion generally doesn't apply to investment properties or houses you haven't lived in as your main home (like many inherited or rental properties), though those often have other offsetting factors like stepped-up basis or depreciation rules. This is where a CPA earns their fee.

Colorado's piece

Colorado taxes capital gains as regular income at the state's flat income-tax rate, so any gain that's federally taxable generally flows through to your Colorado return as well. If your gain is fully excluded federally, there's typically nothing to tax at the state level either. Colorado has no separate real-estate transfer tax statewide, though there can be small local fees in certain areas.

When you might actually owe

You're more likely to owe capital gains tax if: the property wasn't your primary residence (an inherited house you never lived in, or a rental), your gain exceeds the exclusion limits, or you sold a rental and have depreciation to recapture. Even then, stepped-up basis on inherited property frequently keeps the taxable amount low. The point: don't let a vague fear of 'cash sale taxes' drive your decision — run your real numbers with a CPA, because for many sellers the answer is little or nothing.
