The CLARITY Act failed to advance in the Senate, but crypto regulation in the US is moving forward anyway. You’re seeing the SEC, CFTC, and banking regulators introduce new rules.

What is Bitcoin.tax?
Bitcoin.tax is a cryptocurrency tax calculation service that calculates capital gains, trading losses, and income from mining, staking, donations, and spending. Operated by CoinsTax LLC and serving crypto taxpayers since 2014, the software processes transaction histories from centralized exchanges, personal wallets, payment processors, and decentralized protocols into finished tax forms and exports for third-party filing software.
Platform mechanics and chain support
Users import transaction data through exchange API keys, CSV files, or blockchain addresses directly into their accounts. The platform supports trading data from exchanges including Coinbase, Kraken, Binance, Gemini, Bitstamp, KuCoin, and Crypto.com. For on-chain activity, Bitcoin.tax connects with its companion tool Chain Glance. Chain Glance monitors assets, staking rewards, and liquidity pools across 50+ blockchains including Ethereum, Solana, Polygon, Arbitrum, and Optimism before exporting transaction logs into the tax calculation engine.
Accounting methods and reporting
Calculations can be completed using standard cost-basis methodologies such as FIFO, LIFO, average costing, and specific unit identification. The system outputs IRS Form 8949 printable PDFs, attachable trade statements, and digital import files for tax filing software like TurboTax and TaxACT. In response to IRS Revenue Procedure 2024-28, the platform added a Safe Harbor tool that lets US taxpayers create year-end asset snapshots and assign cost-basis lots to individual wallet addresses or exchange accounts.
Pricing, professional services, and regional availability
Bitcoin.tax provides a free tier for basic usage, alongside tiered annual plans that accommodate higher transaction volumes up to several million entries. For users requiring hands-on help, the company operates a Directory of Bitcoin Tax Professionals and runs an accountant portal with dedicated packages for CPAs managing multiple clients. Supported jurisdictions include the United States, Canada, Australia, Germany, the United Kingdom, and any region running on a January 1 calendar tax year.
Trade-offs and risks
Complex on-chain activity relies heavily on the Chain Glance multi-chain tracker. Smart contract interactions or liquidity pool tokens not automatically recognized require manual CSV adjustments. Users syncing exchange accounts must share read-only API keys or export CSVs directly, creating data privacy responsibilities. Margin profit and loss reporting directly from exchange histories is limited primarily to Kraken, requiring manual entries for other derivatives platforms.

Our review
3.6/5
Good
Bitcoin.tax offers long-standing tax calculation with dedicated US safe harbor tools, but handling complex on-chain DeFi activity requires offloading data tracking to a companion app.
Operated by CoinsTax LLC and established on a domain registered in 2014, Bitcoin.tax is one of the earliest crypto tax calculation services. It calculates capital gains, mining revenue, spending, and gift donations. Standard accounting rules supported on the platform include FIFO, LIFO, average costing, and specific unit identification. The platform serves taxpayers in the United States, Canada, Australia, Germany, and the United Kingdom, alongside any jurisdiction operating on a standard calendar tax year starting January 1.
For US filers, the software produces downloadable IRS Form 8949 attachments and data exports compatible with TurboTax and TaxACT. It also includes an IRS Revenue Procedure 2024-28 safe harbor tool, which lets taxpayers transition between accounts and allocate tax lots per wallet before account-by-account tracking requirements take effect. Margin trading reporting is available, though direct exchange import for margin activity is limited specifically to Kraken.
DeFi and multi-chain tracking are not natively integrated into the core dashboard in a single workflow. Instead, CoinsTax directs users to a companion portfolio tool called Chain Glance, which monitors assets across more than 50 blockchains, including Ethereum, Solana, Polygon, Arbitrum, and Optimism. Users track liquidity pools, staking rewards, DeFi positions, and NFT collections on Chain Glance before generating a dedicated CSV to import back into Bitcoin.tax. While this multi-step approach bridges the on-chain gap, it adds friction compared to platforms with integrated chain scanning.
The service suits US and Canadian filers with straightforward centralized exchange histories or mining income. Filers heavily involved in rapid cross-chain DeFi operations may find the two-step Chain Glance workflow cumbersome.

What users say about Bitcoin.tax
Long-term users value Bitcoin.tax for its reasonable pricing, straightforward exports for software like TurboTax, and multi-year trade tracking. However, recent regulatory transitions to per-wallet accounting have led to many complaints about transfers that do not match, missing cost basis, and slow support.

In their own words
“bitcoin.tax I started using them in 2013 when I started investing in crypto and have stayed with them as I feel their service is a good value to me. I manually import all my trades / account info as I see no reason to connect their system to the exchanges.”
“I used Bitcoin.Tax and paid $99 or so for up to 10k transactions and it let me revise any missing data also ask you to create a Fed Safe Harbor Report then will give you several options to export your 8949 file for TurboTax in my case and TT requires a TXFR file and boom uploaded.”
“OP, this is the answer. Very simple, you manually add it in. Bitcoin.tax is a great site, costs a few bucks, but when I was trading hundreds of cryptos on multiple exchanges, this was a lifesaver, less than 1% of tax professionals can wrap their head around complicated crypto taxes.”
“I'm going through a similar situation on my bitcoin.tax account, which I've had since 2013 when I first bought crypto. I've used this company since day one, and always filed / paid taxes using their system and software, when trades were made.”
“bitcoin.tax can not match buy and sell between platform transfer (Need help) I have all three pieces in Bitcoin.Tax: 1. Bittrex buys (2021-2023) ✓. - validated all the buys are correct and year end holdings are correct. 2. Transfers (Bittrex → Coinbase, Nov 2024) ✓.”
“I've used bitcoin.tax for years. But I just had a rude awakening. I created a fresh account and uploaded a single CSV file from an exchange. Then I went to confirm the total gains matched the total of the CSV numbers. But it was off.”
