Do I have to pay tax on crypto if I didn't cash out to my bank?

Yes, in most cases. The common misconception is that tax only applies when you convert crypto back to your local currency. In the US, UK, Australia, and Canada, the taxable event is the disposal — and that includes swapping one crypto for another. Trading Bitcoin for Ethereum is treated as selling Bitcoin at its current value and buying Ethereum. The gain or loss is calculated at the point of the swap, not when you eventually cash out. Transfers between your own wallets, on the other hand, are not taxable events. Moving crypto from one wallet you own to another doesn't trigger any tax. The taxable moment is when the asset changes hands , not when it changes address.

What if I made a loss — do I still need to report it?

You do, and it's actually worth reporting carefully because losses are useful. In all four countries covered by this calculator, capital losses can be used to offset capital gains. If you made a $10,000 gain on one trade and a $4,000 loss on another, you're taxed on a net gain of $6,000. In the US, if your losses exceed your gains for the year, you can offset up to $3,000 of ordinary income and carry the rest forward to future years. The UK, Australia, and Canada have their own rules for loss carry-forward, but the principle is the same — losses reduce your tax bill, so they're worth tracking.

Does it matter which crypto I sold — Bitcoin, Ethereum, altcoins?

No. The tax rules don't distinguish between different cryptocurrencies. Bitcoin, Ethereum, Solana, or any other token — they're all treated the same way by tax authorities in these four countries. What matters is the gain or loss on the specific asset you disposed of, calculated against its cost basis. The only exception worth noting is stablecoins, which in theory are subject to the same rules, even though the gain is often negligible due to the stable price.

What is cost basis and why does it matter so much?

Your cost basis is what you originally paid for the crypto, including any fees at the time of purchase. It's the number that your gain or loss is measured against. If you paid $5,000 for one Bitcoin and sold it for $8,000, your cost basis is $5,000 and your gain is $3,000. Where cost basis gets complicated is when you've bought the same asset multiple times at different prices. If you bought Bitcoin three times — at $20,000, $30,000, and $50,000 — and then sell one coin, which purchase does the sale relate to? The answer depends on the accounting method you use: FIFO means you're selling the oldest purchase first, HIFO means you're selling the highest-cost purchase first, which typically minimises your gain. Different countries allow different methods, and the choice can make a meaningful difference to your tax bill.

What about staking rewards and airdrops?

These are generally taxed as income rather than capital gains. In the US, UK, Australia, and Canada, receiving staking rewards or an airdrop is treated as receiving income at the market value of the tokens on the day you received them. That value becomes your cost basis. If you later sell those tokens, any additional gain above that cost basis is then a capital gain. So staking rewards can be taxed twice in a sense — once as income when received, and again as a capital gain if they appreciate before you sell. This calculator focuses on capital gains from buying and selling; staking and airdrop income is a separate calculation.

How accurate is this calculator?

It gives you a solid estimate based on the published tax rates and rules for each country as of 2026. For most straightforward buy-and-sell transactions, the figure should be close to what you'd calculate manually. What it doesn't account for: state or provincial taxes on top of federal rates, losses carried forward from previous years, more complex scenarios like DeFi transactions, NFTs, or crypto received as payment for work. For a simple trade — bought some Bitcoin, sold it later — the estimate will be reliable. For anything more complex, treat the number as a starting point and run it past a tax professional.

A note on using this calculator

Tax rules change, and they've been changing quickly in the crypto space. The rates and rules built into this calculator reflect the current position in each country as of 2026, but tax legislation can be updated at any time. This tool is designed to give you a clear, honest estimate — not to replace professional advice. If you're dealing with large gains, multiple years of transactions, or any uncertainty about your situation, speaking to a qualified tax adviser in your country is the right move.
