Cost basis is the original value of an asset for tax purposes — generally what you paid for it, including fees, at the time of acquisition. When you later sell, trade, or spend that asset, cost basis is subtracted from the proceeds to calculate your capital gain or loss.
Crypto cost basis tracking is genuinely harder than for a typical brokerage account because assets often move across multiple wallets and exchanges, and different tax lot accounting methods (such as FIFO or specific identification) can produce different reported gains from the same set of trades. Under current IRS guidance, crypto is treated as property, so this calculation applies to sales, trades, and even spending crypto on goods or services.
Keeping records of acquisition price, date, and fees for every transaction makes year-end tax reporting far easier. This is general information, not tax advice; consult a qualified professional for your specific situation.
Key takeaways
- Cost basis is what you paid for a crypto asset, including fees, at acquisition, and it is subtracted from proceeds to calculate a capital gain or loss when you dispose of it.
- Tracking cost basis is harder for crypto than for a traditional brokerage account because the same assets often move across multiple wallets and exchanges, making a single unified record difficult to maintain.
- Different accounting methods, such as FIFO or specific identification, can produce different reported gains from the exact same set of trades. This is general information, not tax advice; consult a licensed tax professional.
Cost Basis — frequently asked questions
What counts as cost basis for crypto?
Cost basis generally includes the price you paid for the crypto plus any fees at the time of acquisition. It is used to calculate your gain or loss when you later sell, trade, or spend that crypto.
Why is crypto cost basis harder to track than stocks?
Crypto often moves across multiple wallets and exchanges that do not share records automatically, unlike a single brokerage account. Keeping detailed records of acquisition price, date, and fees for every transaction helps simplify reporting.
Does the accounting method I choose change my tax bill?
It can. Methods like FIFO or specific identification can produce different reported gains from the same trades. This is general information, not tax advice; a qualified tax professional can advise which method fits your situation.
