Tax & Accounting

Koinly is a cryptocurrency tax platform that helps individual investors and accountants generate compliant capital gains reports across more than twenty jurisdictions. The company was founded in 2018 by Robin Singh and operates under Koinly Pte Ltd, registered in Singapore. The product targets the gap between cryptocurrency trading and traditional tax filing software, automating the steps required to consolidate transaction history from a large number of exchanges, wallets, and on-chain protocols into a single report.

Users connect their accounts to Koinly through read-only API keys or public wallet addresses, after which the platform imports trades, transfers, staking rewards, NFT activity, and DeFi interactions. Koinly reconciles those entries against historical market prices, calculates cost basis according to the accounting method permitted in the user's country (such as FIFO, LIFO, or average cost), and produces a finalised report in the format expected by local tax authorities. The reports cover capital gains, income, and gifts, and can be exported as printable PDFs or as imports for filing tools used by professional preparers.

Koinly supports integrations with hundreds of cryptocurrency exchanges, wallets, and DeFi protocols, including the major platforms most retail users hold accounts on, as well as smaller venues and chain-level address imports. The service is offered through a free tier that lets users preview their tax position and paid plans that scale with annual transaction count, with discounts for accountants managing multiple clients. A separate accountant directory connects users with crypto-aware tax preparers, and the platform maintains a regularly updated blog covering tax rules and reporting practice in supported countries.

CoinLedger (formerly known as CryptoTrader.Tax) is a cryptocurrency tax software platform that automates the calculation of capital gains, losses, and income from crypto transactions. The platform connects to exchanges, wallets, and blockchain networks to import transaction history, then generates country-specific tax reports and forms for filing.

Founded in 2018 and headquartered in Saint Louis, Missouri, the company operates under the legal name Coin Ledger, Inc. It integrates with over 200 exchanges and wallets, including Coinbase, Kraken, Binance, MetaMask, and Uniswap, and supports DeFi, NFT, and on-chain transaction reporting. CoinLedger also offers portfolio tracking at no cost and a tax-loss harvesting tool to help investors identify potential savings.

The platform supports international tax reporting across multiple currencies and integrates directly with tax filing software such as TurboTax. A professional assistance service is available for users who prefer guided tax preparation.
