Key Features for Calculating Taxes with Koinly (Card Format / Box Format)

Automated Tax Reports

No more wasting hours figuring out the math or formatting data. Koinly automatically categorizes your transactions and generates comprehensive, ready-to-file documents—such as IRS Form 8949 and Schedule D—in under 20 minutes. It also provides localized tax reports fully compatible with major tax software like TurboTax and H&R Block, tailoring the final output to your specific jurisdiction.

Intelligent Transfer Matching

One of the biggest headaches in crypto tax reporting is tracking assets as they move across platforms. Koinly's smart algorithms automatically detect and track transfers between your own wallets, ledgers, and exchange accounts. This ensures you never lose sight of your original cost basis, preventing you from paying unnecessary capital gains taxes on simple internal transfers.

Comprehensive Ecosystem Support (DeFi & NFTs)

Koinly seamlessly handles advanced decentralized activities across the entire Web3 space. Whether you are staking on Solana, providing liquidity on Polygon, lending on Curve, or trading NFTs, Koinly can handle it all. By integrating with over 800+ platforms, it captures every trade, reward, and airdrop to keep your ledger perfectly balanced.

Proactive Portfolio Tracking & Tax-Loss Harvesting

Beyond year-end tax reporting, Koinly acts as a real-time portfolio manager. You can visualize your total holdings, track ROI, and monitor your overall growth on a beautiful dashboard. Additionally, its automated tax-loss harvesting tools allow you to easily visualize the financial impact of selling specific underperforming assets, helping you strategically reduce your tax liability before the financial year ends.

Koinly Terms, Conditions & Country Availability

Koinly is a global crypto tax platform used by individual investors and tax professionals across multiple continents. However, there are a few important considerations and limitations to keep in mind before you sync your MEXC account:

Supported regions:

Koinly is available globally and provides dedicated, localized tax reporting workflows for users in over 100+ countries, including the United States, United Kingdom, Canada, Australia, and Germany. The platform automatically generates tax reports that align with local tax authority requirements, such as IRS Form 8949 and Schedule D for US taxpayers.

MEXC Integration Limitations (API & CSV):

• API Expiration: The dedicated MEXC Tax API successfully pulls historical data across multiple fiscal years. However, the Tax API key is only valid for three months; once expired, you will need to generate a new key on MEXC to sync future data.
• Account Eligibility: The MEXC Tax API is currently only available for individual users. Institutional accounts are not supported via API at this time and must use the CSV export method.
• CSV Formatting Requirements: Exported MEXC CSV files must be generated in English to format correctly within Koinly. Additionally, promotional sign-up or trading bonuses (like airdropped USDT) cannot be imported automatically and must be added manually to your ledger.

Regulatory limitations:

Koinly is an automated cryptocurrency tax calculator, but it does not provide formal tax advice and is not a licensed tax advisory service. Users are solely responsible for ensuring their finalized reports comply with local tax laws. In jurisdictions where crypto tax regulations are still evolving or unclear, users should consult a qualified crypto tax advisor or CPA before filing their returns.

Not available for:

Koinly's services may not be fully compliant or accessible in jurisdictions with outright cryptocurrency bans or heavy trading restrictions. Always verify the legal status of crypto trading and the use of third-party tax reporting tools in your specific country.

Data and privacy:

Koinly utilises enterprise-grade security to protect your financial data. Information is secured using 256-bit encryption and hosted on robust AWS infrastructure. Furthermore, Koinly only requests "read-only" API access from MEXC, meaning the software can never access, move, or withdraw your funds. For full details on data handling, refer to Koinly’s official Privacy Policy .

Pricing:

Generating a Tax API on MEXC is completely free, and Koinly allows you to import your data and track your portfolio at no cost. However, downloading your finalized, ready-to-file crypto tax reports requires a paid subscription. Koinly offers tiered pricing plans that scale based on your total transaction volume for the tax year. For the latest pricing tiers, visit Koinly Pricing .

Frequently Asked Questions

Is it safe to connect my wallets and exchanges to Koinly?

Yes. Koinly utilizes enterprise-grade 256-bit encryption to protect your data. When connecting via API, Koinly only requests "read-only" access. This means the software can view your transaction history to calculate your taxes, but it physically cannot move, withdraw, or trade your funds.

What accounting methods does Koinly support?

Koinly supports a wide variety of cost-based accounting methods to align with your specific local tax laws. Depending on your country's regulations, you can configure Koinly to calculate your taxes using FIFO (First In, First Out), LIFO (Last In, First Out), HIFO (Highest In, First Out), or Average Cost.

Can I use Koinly to file taxes for previous years?

Yes. If you failed to report your crypto activity in previous years, you can import your complete historical data into Koinly. The platform allows you to generate retrospective tax reports for any past financial year so you can easily amend your prior tax returns.

Does Koinly support DeFi and NFT transactions?

Absolutely. Koinly is built for the modern Web3 ecosystem. It automatically detects and categorizes complex decentralized finance (DeFi) activities, including liquidity pooling, staking, bridging, and NFT trading across hundreds of different blockchains.

Can I import my Koinly report directly into TurboTax?

Yes. Koinly is designed to work seamlessly with traditional tax preparation software. It generates specific, natively formatted files that can be directly imported into platforms like TurboTax, H&R Block, and TaxAct.

In which countries can I use Koinly?

Koinly provides dedicated, localized tax reporting for over 20 countries. It automatically generates the specific forms required by local tax authorities in jurisdictions such as the United States (IRS Form 8949), the United Kingdom (HMRC), Canada (CRA), Australia (ATO), Germany, and Sweden.

What if my Koinly transaction data is missing or incorrect?

Koinly features a smart, built-in error-checking system. If your imported data has gaps, the software will automatically flag issues like missing purchase histories, unmatched transfers, or negative balances. This allows you to easily identify and fix the discrepancies before you generate your final tax reports.

Does MEXC have its own built-in tax tools?

Yes. In addition to the Tax API, MEXC offers a native Crypto Tax Calculator . This is a free, lightweight online estimation tool. By inputting your transaction parameters (like buy/sell price and holding period) and your annual income, you can get a quick estimate of your tax liability. However, for comprehensive multi-year reporting, a dedicated tool like Koinly is recommended.

Does MEXC automatically deduct taxes?

No. Managing tax liabilities is the responsibility of the individual investor. You must calculate and pay any taxes owed on your capital gains or income directly to your local tax authority.

Are crypto-to-crypto trades on MEXC taxed?

Yes. In most jurisdictions, exchanging one digital asset for another (e.g., swapping BTC for XRP) is viewed as a taxable event and treated as a sale at fair market value.

Does MEXC provide end-of-year tax reports?

Because MEXC serves a global user base with highly varied regulatory environments, it does not provide finalized tax reports. You will need to export your transaction history and use a third-party calculator to process the data.
