Are Bitcoin.Tax and CryptoTaxCalculator both legit and useful websites?

Yes. Both of these sites are well-known and reputable crypto tax tools. However, the right tool for the job depends on your needs and transactions. While Bitcoin.Tax offers a simpler interface, it comes at a better price, whereas CryptoTaxCalculator offers more features and integrations at a cost.

In this guide, we’re comparing the two in-depth to see which comes out on top.

Winner: CryptoTaxCalculator

CryptoTaxCalculator takes the lead when it comes to supported platforms with support for more than 800 exchanges, wallets, and blockchains compared to Bitcoin.Tax’s approximate 50 exchanges and blockchains. 

In particular, when it comes to DeFi investments, CryptoTaxCalculator is likely the better option between the two as it offers far superior DeFi support than Bitcoin.Tax.

What Koinly offers...

While CryptoTaxCalculator does offer excellent DeFi support, this comes at a cost as smart contract support and automated on-chain transactions only come with the plan starting at $129 a year. Meanwhile, Koinly offers support for more than 800 integrations - including 80+ smart contract capable blockchains and their DeFi ecosystems - on its free plan for up to 10,000 transactions.

Winner: CryptoTaxCalculator

Once again, CryptoTaxCalculator takes the lead when it comes to portfolio tracking, with far more functionality and features than Bitcoin.Tax. While Bitcoin.Tax will let you import your data, it lacks a functional dashboard to view key data like your holdings, realized and unrealized gains and losses, ROI, and more.

What Koinly offers...

Koinly offers everything CryptoTaxCalculator does when it comes to portfolio tracking plus an NFT dashboard, tax optimization tool, and asset maturity dashboard, all free of charge.

DeFi, NFTs, margin trading, and derivatives

Winner: CryptoTaxCalculator

Unsurprisingly given it has far more integrations. CryptoTaxCalculator comes out on top when it comes to support for more advanced transactions like DeFi, derivatives, margin trading, and NFTs. While Bitcoin.Tax supports basic income, and supports some smart contract capable blockchains, the tool is far more limited in terms of the data it imports automatically and how accurate it is.

What Koinly offers...

Koinly supports DeFi, derivatives, margin trading, NFTs, lending, income, and more - and it’s able to automatically tag these the majority of the time. The key difference between Koinly and CryptoTaxCalculator is the price you’ll pay as CryptoTaxCalculator only offers smart contract support from $129 a year, while Koinly offers it on its free plan for up to 10,000 transactions.

Free plan

Winner: CryptoTaxCalculator

Both tools offer a free plan that lets you import transactions and review your transaction data, but CryptoTaxCalculator offers a lot more functionality in its free plan including richer transaction detail, a superior portfolio tracker and the ability to view available reports before you buy.

Paid plan…

When it comes to pricing, Bitcoin.Tax comes out on top with its lowest plan starting at $49.95 a year for 1000 transactions compared to CryptoTaxCalculator’s $49 a year for 100 transactions. Of course, this price difference is reflected in the limited features Bitcoin.Tax offers, but it’s a suitable option for investors with simpler transactions across fewer blockchains.

What Koinly offers...

Koinly offers everything CryptoTaxCalculator offers and more - including a free NFT dashboard, tax loss harvesting tool, asset maturation tools and even the ability to preview a free tax summary so you can make sure you’re happy with the figures before you ever spend a dime.

Usability and features

Winner: CryptoTaxCalculator

Both platforms take a little bit of getting used to - as do most crypto tax calculators - but CryptoTaxCalculator offers a far more inuitive experience for users than Bitcoin.Tax which works well but takes a lot of manual work to get everything looking how you want it to. CryptoTaxCalculator on the other hand offers better transaction support and filtering, customizable tax settings, and automatic error detection to make it easier to import and organize your transaction data.

What Koinly offers...

Koinly offers everything CryptoTaxCalculator offers like transaction tags, filtering, tax settings, and automatic error detection. It also offers a wealth of self-help content to help you resolve common data issues and queries in the form of more than 50 help guides, nearly 200 YouTube videos, and AI support.

Customer support

Both CryptoTaxCalculator and Bitcoin.Tax have good Trustpilot reviews at an average of 4.8 stars and 4.5 stars respectively. CryptoTaxCalculator offers live chat and email support, while Bitcoin.Tax offers only email support for customers.

What Koinly offers…

Koinly has outstanding customer service with an average of 4.6 stars on Trustpilot from more than 1,800 reviews and offers live chat and email support. As well as this, Koinly offers an expert review service starting from $499 (depending on seasonal demand). This service gets a Koinly expert to go through all of your transactions with a fine-tooth comb to ensure everything is as it should be so you can file with confidence knowing your calculations are correct.

Reputation and security

CryptoTaxCalculator is backed by Coinbase Ventures and has partnerships with some experienced crypto accounting firms. The platform is SOC 2 certified, but did however suffer a data leak as a result of a third party gaining unauthorized access to CryptoTaxCalculator's system, resulting in user IDs, email addresses, password hashes, and public blockchain wallet addresses being compromised.

Comparatively, it’s not clear what partnerships or security protections Bitcoin.Tax has in place, however, it doesn’t seem as though the platform has ever suffered a security breach from user feedback.

What Koinly offers…

Koinly is partnered with the leading names across the industry including Kraken, Coinbase AU, Binance, and leading tax platforms globally. The platform is ISO 27001 and SOC 2 certified and has never suffered a security breach.

For the US, both CryptoTaxCalculator and Bitcoin.Tax let users export a number of forms including Form 8949 and Schedule D, as well as TurboTax and TaxAct exports.

Globally though, CryptoTaxCalculator marginally takes the lead with reports for Australia and a generalized report that may help investors in other countries file.

What Koinly offers...

Koinly offers outstanding support for investors - wherever you live, with dedicated reports for more than 10 countries, as well as a Complete Tax Report that can help investors in more than 100 countries file easily.

Conclusion: Which is better?

Bitcoin.Tax will get the job done if you have simple transactions on major exchanges and blockchains, but for anything more complicated, you’re likely better off using CryptoTaxCalculator.

This said, Koinly tops both with more features for far less. And while we might be a little biased, you can compare the two yourself in our Koinly vs. CryptoTaxCalculator guide to see why we’re the market leader in what we do.
