Nah Crypto Tax Tracker

Nah Crypto Tax Tracker is a spreadsheet template (.xlsx; works in Google Sheets and LibreOffice) plus a step-by-step PDF guide. Log buys and sells (swaps as a sell plus a buy) and get FIFO cost basis, realized gain/loss per year, and current holdings by token. Airdrops, staking and transfers are explained in the guide but not calculated. FIFO only; guide covers US, Switzerland and Germany. No sign-up and no wallet connection: your data stays in your own file. Price: 29 USDC one-time, paid on Solana. Not tax advice: it organises records and does not determine what you owe; consult a qualified tax professional.
