KŌINItax

Paste a public wallet address. See your crypto taxes.

KŌINItax is a read-only tax calculator. It reads the public, on-chain transaction history of any wallet address you paste — Ethereum and EVM chains, Solana, Bitcoin — prices each transaction in your local currency, separates income from disposals and self-transfers, and shows you where you stand for the tax year. In seconds, free.

WHAT YOU GET • Net capital gain or loss, split short- and long-term, plus ordinary income • Any recent tax year • 34 countries, each in its own currency and under its own cost-basis conventions • FIFO or HIFO • Anything uncertain is flagged for review rather than guessed

WHAT THIS APP IS NOT • Not an exchange. You cannot buy, sell, trade, or convert anything. • Not a wallet. It never holds, sends, or receives funds, and never asks for a private key or seed phrase. • No account, no sign-in, no purchase.

PRIVACY Public addresses only. Nothing is stored on our servers unless you ask us to save a report.

Informational only — not tax, legal, or accounting advice.
