You sold some bitcoin at a profit last year and now you're staring at a tax form wondering where to start. The good news: most of what you owe comes down to one number — your gain, not the size of the sale. Get that straight and the rest of the filing gets much simpler.
What counts as a taxable disposal
The IRS treats crypto as property, so tax applies when you dispose of it. Disposal is broader than cashing out to dollars. Swapping bitcoin for ether counts. Buying a laptop with crypto counts. Spending a small amount on coffee counts too, even though the gain is usually pennies.
- Selling crypto for fiat currency
- Trading one coin for another
- Using crypto to buy goods or services
- Receiving crypto as payment for work, taxed as income when you get it
Buying and holding isn't taxable. Neither is moving coins between wallets you control. The trigger is a change of ownership or a conversion into something else.
How your holding period changes the rate
Hold for more than a year and the gain is long-term, taxed at lower capital gains rates. Sell within a year and it's short-term, taxed as ordinary income. First-time filers often sell quickly and assume the friendlier rate applies. It doesn't.
A worked example: the $600 gain
Say you bought $2,000 of bitcoin in March. By November it's worth $2,600 and you sell. Your gain is $600. Because you held under a year, that $600 is short-term and gets added to your ordinary income, so the tax depends on your bracket rather than any flat crypto rate.
Now the common mistake. You spent the $2,600 on a new phone and never touched your bank account. Some filers figure no cash means no tax. Wrong — the $600 gain is still reportable. The same rule applies if you swapped that bitcoin for ethereum instead of selling: the gain is triggered either way.
Record-keeping is where first-timers lose money
You need four things for every coin: the date you acquired it, the amount you paid including fees, the date you disposed of it, and the proceeds. Without them you can't calculate gain or loss, and you may overpay because you can't prove your cost basis.
Build a simple log now
A spreadsheet works fine. One row per acquisition, one row per disposal, matched up. Most exchanges let you export transaction history, which saves hours of manual entry. Download it before you file, not after.
Don't skip the small trades
Dozens of small swaps add up. Each one carries its own gain or loss and its own holding period. Skipping them because they seem too small to matter is a common error that leaves your totals wrong.
Losses, reporting, and the forms you'll see
If some positions lost money, those losses can offset gains and reduce your taxable total. You can't deduct more capital losses than you have gains plus a limited amount against ordinary income, but carrying losses forward is allowed. Report everything on the appropriate capital gains schedule, and answer the digital asset question on your main return if it applies to you.
| Situation | Taxable? |
|---|---|
| Bought and still holding | No |
| Sold at a gain | Yes, on the gain |
| Swapped coin for coin | Yes, on any gain |
| Moved between your own wallets | No |
Frequently asked questions
Do I owe tax if I only made a small profit?
Yes, in most cases. There's no minimum gain that exempts you from reporting a disposal. The amount owed may be small, but the transaction still belongs on your return.
What if I lost my purchase records?
Export history from the exchange where you bought the crypto and check your email for confirmation receipts. If you truly can't establish cost basis, the tax treatment can be less favorable, so reconstructing records is worth the effort. Start the export early — some platforms take time to process requests.
Is receiving crypto as payment different from buying it?
Yes. Crypto you receive for work or services is generally treated as income at its value when received, and that value becomes your cost basis for any later sale. You could owe income tax on receipt and capital gains tax later if the price rises before you sell.
Do I need to report crypto I never sold?
Holding alone isn't a taxable event, so unrealized gains aren't taxed. You may still need to answer the digital asset question on your return depending on your situation. Check the current form instructions rather than relying on last year's version.
Before you open the tax software, log into every platform you used this year and export the full transaction history. Total your gains and losses into one sheet first — the filing itself goes faster once the numbers are already in front of you.
