Free Crypto Tax Software — Koinly (2026 Guide)

Koinly is one of the most popular crypto tax and portfolio tracking softwares available today. It helps crypto investors automatically track their trades, calculate taxable gains/losses, and get insight into their overall portfolio — all from one dashboard.

What Is Koinly?

Koinly is a web-based crypto tax solution that connects with your wallets, exchanges, and blockchain addresses to import all your transactions automatically. It supports hundreds of exchanges, wallets, and thousands of tokens — making it easy to track diverse crypto activity.

With Koinly, you can:

• Sync trading history via API or upload CSV files.
• See a portfolio overview with realized/unrealized gains.
• Classify and tag transactions (like staking, swaps, NFTs).
• Preview capital gains and estimate your tax liability.

Free Plan — What You Get

Koinly’s free tier is genuinely free to use forever and includes the following benefits:

• Import & Track Transactions — You can import your entire crypto history from wallets and exchanges — up to 10,000 transactions — without paying anything.
• Unlimited Wallet & Exchange Connections — You can connect multiple wallets and exchange accounts, giving a single consolidated view of your crypto holdings.
• Portfolio Tracking & Tax Estimates — The free plan lets you preview tax estimates and view realized/unrealized gains across assets and chains.
• DeFi & NFT Support Included — Even complex transactions like DeFi yield farming or NFT sales can be tracked in the free version.

Limitations of the Free Version

• No Downloadable Tax Reports — You can calculate and preview your tax liability, but to actually generate and download tax reports (e.g., ready-to-file PDFs or IRS/other tax form outputs), you need a paid Koinly plan.
• Export Features Limited — Exporting tax summaries to official filing formats (like Form 8949 in the U.S.) or other tax apps is only available in paid tiers.

How Koinly Works (Simple Steps)

• Create Your Free Account — Sign up on Koinly’s website.
• Connect Your Wallets/Exchanges — Use APIs or upload CSVs to import data.
• Review Transactions — Koinly automatically categorizes buys, sells, trades, staking, DeFi events, NFTs, etc.
• See Your Portfolio & Tax Preview — Get an up-to-date snapshot of gains, losses, and potential tax owed.
• Upgrade (Optional) — If you need downloadable tax reports, choose a paid plan.

Who Is Koinly Best For?

• Retail Investors — Casual holders who want to track gains and see potential tax owed.
• Active Traders — Those with multiple wallets and exchanges who want consolidated records.
• DeFi/NFT Users — Users with complex transactions that are hard to track manually.

It’s a particularly useful starting point if you want a free way to monitor and estimate your crypto tax before deciding whether to pay for full annual tax report generation.
