Koinly
Review in progressComprehensive crypto tax calculator
The most complete tax solution for Bitcoin holders who also interact with other chains. Wide exchange integration, solid on-chain tracking, and clear tax reports. The free tier lets you see your tax liability before paying. Best for users with transactions across multiple platforms.
CoinTracker
Review in progressPortfolio tracking with tax reporting
Strong portfolio tracking combined with tax reporting. The interface is cleaner than Koinly for simple portfolios. But pricing is higher, the free tier is more limited, and complex on-chain transactions sometimes need manual correction.
TaxBit
Review in progressEnterprise-grade crypto tax compliance
Originally built for enterprises and now available to consumers. The compliance pedigree is strong - TaxBit powers tax reporting for several major exchanges. But the consumer product is less polished than Koinly or CoinTracker, and the free tier relies on exchange partnerships.
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.
