Koinly
Review in progressBest overall for most Bitcoin holders
The strongest combination of usability and Bitcoin-specific support. Koinly handles on-chain transactions, Lightning, and most major exchange imports cleanly. The interface is clear, the tax reports are well-formatted, and it works in most countries. Best choice for the majority of holders with moderate transaction volume.
CoinTracker
Review in progressStrong integrations including Coinbase
CoinTracker has deep Coinbase integration and a clean UI. Backed by Coinbase itself (which raises mild independence questions). Works well if Coinbase is your primary exchange. The free tier is limited; paid plans are competitive. Slightly less polished for complex on-chain history or Lightning.
TaxBit
Review in progressEnterprise-grade with consumer option
TaxBit started in enterprise and expanded to consumers. The product is thorough and accurate, with strong audit support. More expensive than Koinly or CoinTracker for individual users, but worth it if you have complex situations - large transaction volumes, business income, or need professional-grade reporting.
What to Know About Bitcoin Taxes
The essentials before you pick a tool.
Why Bitcoin taxes are complicated
The IRS treats Bitcoin as property, not currency. Every sale or exchange is a taxable event requiring a gain/loss calculation based on your cost basis. This includes selling BTC for dollars, using BTC to buy something, and trading BTC for another asset. Mining income and staking rewards are taxed as ordinary income at the time of receipt.
Cost basis methods matter
Your cost basis is what you paid for each Bitcoin. When you sell, the gain or loss depends on which coins you're treating as sold - FIFO (first in, first out) is the IRS default, but HIFO (highest in, first out) can minimize taxable gains. Tax software handles these calculations automatically, but you need to be consistent year to year.
Exchange imports vs manual entry
Good Bitcoin tax software imports transaction history directly from exchanges via API or CSV. The quality of exchange integrations varies by platform. If you've used multiple exchanges over several years, test that your specific exchanges are supported before paying for an annual subscription.
On-chain and Lightning complexity
If you've sent Bitcoin on-chain or used the Lightning Network, your tax situation is more complex than a simple exchange buy-and-sell. On-chain sends can look like taxable disposals to unsophisticated software. Koinly handles on-chain history best among consumer tools.
Free tiers and pricing
Most Bitcoin tax tools have free tiers limited to a certain number of transactions (usually 25-100). If you've been dollar-cost averaging monthly for several years, you likely have hundreds of transactions and will need a paid plan. Compare annual pricing vs transaction limits before committing.
When to bring in a professional
If you've mined Bitcoin, received it as income, have multi-year basis issues, or have not reported in prior years, consider a CPA familiar with crypto taxes. Tax software handles the data work - it doesn't give advice on strategy, amended returns, or audit defense.
