Why Waiting Until Tax Season Is a Mistake
Most crypto investors do nothing about taxes until February or March, then spend weeks trying to reconstruct a year of transactions. This approach has three serious problems. First, exchanges sometimes close or change their data export formats, making historical data harder to retrieve. Second, misclassified transactions (a transfer marked as a sale, for example) compound over time and become harder to untangle. Third, you miss the opportunity to reduce your tax bill through strategies like tax-loss harvesting, which must be done before December 31.
A year-round system does not require much time. The goal is to keep your tax software accurate and up-to-date throughout the year so that generating your final report in January is a 10-minute task, not a 10-hour one.
The 6-Step Year-Round Crypto Tax System
Connect all exchanges and wallets to tax software
Link every exchange account and wallet address to a crypto tax tool like CoinLedger or Koinly at the start of the year. This captures all transactions automatically.
Review your transaction feed monthly
Spend 5–10 minutes each month reviewing your transaction feed in the tax software. Flag any misclassified transactions (e.g., a transfer incorrectly marked as a sale).
Record cost basis for any manual transactions
If you receive crypto as a gift, earn it as income, or acquire it through a method the software cannot auto-detect, manually add the transaction with the correct date and fair market value.
Run a mid-year tax estimate in Q3
In July or August, run a preliminary tax report to estimate your capital gains liability for the year. This gives you time to harvest losses before December 31 if needed.
Harvest losses before December 31
If you have unrealised losses on positions, consider selling before year-end to offset gains. This is called tax-loss harvesting. Be aware of wash sale rules (currently do not apply to crypto but may change).
Generate your final tax report in January
Once the tax year closes, generate your final Form 8949 and Schedule D report. Export it and give it to your CPA or import it directly into TurboTax or H&R Block.

Frequently Asked Questions
How often should I check my crypto tax software?
Monthly is ideal. A 5–10 minute monthly review catches misclassified transactions before they compound into a larger problem at tax time. At minimum, do a quarterly review.
What is crypto tax-loss harvesting?
Tax-loss harvesting means selling a crypto asset at a loss to offset capital gains elsewhere in your portfolio, reducing your overall tax bill. For example, if you have $5,000 in gains from Bitcoin and $2,000 in unrealised losses on Ethereum, selling the ETH locks in the loss and reduces your net taxable gain to $3,000.
Do wash sale rules apply to crypto?
As of 2026, wash sale rules do not apply to cryptocurrency (they apply to stocks and securities). This means you can sell crypto at a loss and immediately rebuy it to lock in the tax loss while maintaining your position. However, this may change — proposed legislation has sought to extend wash sale rules to crypto.
What if I forgot to track my crypto transactions from previous years?
Most crypto tax software can import historical transaction data going back several years from exchanges. Connect your accounts and let the software reconstruct your history. For very old transactions or closed exchanges, you may need to use blockchain explorers or contact the exchange for records.
Is it worth paying for crypto tax software year-round?
Most crypto tax tools charge per tax year, not as a monthly subscription. You pay once to generate your annual report. Tools like CoinLedger and Koinly let you track transactions for free throughout the year — you only pay when you want to download the tax report.
