How to Generate a Crypto Tax Report for Free (No Account Needed)
You need accurate transaction records to file a crypto tax return. WalletLens exports a complete transaction history CSV — free, no account — that you can hand to your accountant or import into Koinly or CoinTracker.
Crypto taxes are complicated, but the starting point is simple: you need an accurate record of every transaction. What you bought, how much, at what price, and on what date. Without this, calculating capital gains is guesswork.
Most people discover this problem only at tax time — when they have to reconstruct months of trades across multiple exchanges, each with their own export formats and missing historical data. WalletLens is designed to prevent that problem: log trades as you make them (via voice, screenshot, or manual entry), and at tax time export one clean CSV that covers everything.
What counts as a taxable crypto event?
Tax rules vary by country, but in most jurisdictions the following are taxable events:
- Selling crypto for fiat (e.g. selling BTC for USD) — short or long-term capital gain/loss depending on how long you held it
- Trading one crypto for another (e.g. swapping ETH for SOL) — treated as a sale of the first asset at market value
- Spending crypto on goods or services — treated as a disposal at market value
- Receiving crypto as income (mining, staking, airdrops) — often taxed as income at market value when received
Holding crypto is generally not a taxable event. Transferring between your own wallets is not a taxable event either (though you need records to prove the coins are still yours).
Why accurate transaction records matter
The cost basis of an asset — what you paid for it — determines the capital gain or loss when you sell. If you bought Bitcoin in multiple batches at different prices, the accounting method you use (FIFO, LIFO, or average cost) affects your tax liability significantly.
For this reason, tax authorities expect you to have a detailed transaction record: date, quantity, price per unit, and total value for every acquisition and disposal. "I think I paid around $40K for my Bitcoin" is not sufficient for a tax return.
How WalletLens helps with crypto taxes
WalletLens is not a dedicated tax tool — it is a portfolio tracker. But it serves two crucial functions for tax season:
1. Keeping ongoing records. By logging trades as you make them (voice import, screenshot import, or manual entry), you build a complete transaction history throughout the year. You are not scrambling to reconstruct it in April.
2. Exporting a clean CSV. At tax time, you export your full transaction history as a CSV file. This gives your accountant or a tax tool exactly what they need: a row per transaction, with date, asset, quantity, price, and type (buy, sell, transfer).
How to export your transaction history for tax
1. Open WalletLens and ensure all your trades are logged.
2. Go to Settings → Export.
3. Tap "Transaction History CSV."
4. Your browser downloads the file immediately.
5. Open in Excel, share with your accountant, or upload to a tax tool.
Which tax tools accept the WalletLens CSV?
The WalletLens transaction history export is compatible with most major crypto tax platforms:
Koinly: Import → Custom CSV → map the WalletLens columns. Koinly supports most countries and automatically calculates gains, losses, and income.
CoinTracker: Accepts generic CSV uploads. The free tier covers up to 25 transactions.
CryptoTaxCalculator: Supports custom CSV import with column mapping. Covers Australia, UK, US, Canada, and more.
TurboTax: Import the CSV under the cryptocurrency section for US filers.
Your accountant: Simply email the CSV. Any accountant who handles crypto will know what to do with a transaction log in this format.
Cost basis method: what WalletLens uses
WalletLens tracks your average cost basis — the weighted average price you paid across all purchases of an asset. This is the most commonly used method in many jurisdictions (particularly for crypto held without specific lot identification). The average cost is displayed live on your dashboard and is reflected in the transaction history export.
If your tax jurisdiction or accountant requires a specific lot identification method (FIFO, LIFO, HIFO), you may need to re-sort the exported transactions accordingly — a tax professional can advise on which method applies to you.
Important note
WalletLens provides transaction export as a tool for record-keeping. It does not provide tax advice, legal advice, or officially certified tax reports. Laws vary by country and change frequently. Always consult a qualified tax professional for your specific situation.
