How to Report Your GMO Japan Taxes in 2026

What is GMO Japan?

GMO Japan is a centralized cryptocurrency exchange for buying, selling, and trading Bitcoin and other crypto assets against Japanese yen. Users can place spot trades through its exchange interface, use leveraged trading, set up recurring purchases, and access services such as staking or crypto lending where available. For tax reporting, GMO Japan users may need a clear record of their crypto activity, and this guide shows how to handle that with Coinpanda.

How to do your GMO Japan taxes

You can easily report your GMO Japan taxes by connecting your GMO Japan account to Coinpanda using the API or by uploading a CSV file. Coinpanda automatically imports your transactions, calculates your capital gains and income, and generates ready-to-file tax reports for GMO Japan.

Does GMO Japan provide tax documents?

Typically, exchanges don't provide finalized tax documents for their customers, and GMO Japan is no exception. It's hard for an exchange to build tax logic that serves customers across many jurisdictions. Hence, it's more practical for a customer to use a tax platform like Coinpanda.

How are GMO Japan transactions taxed?

The exact tax implications on GMO Japan transactions depend on which country you live in and the type of transactions you have made. In general, you must pay either capital gains tax or income tax on your cryptocurrency transactions on GMO Japan.

• Capital gains tax: Whenever you sell a cryptocurrency for more than you purchased it for, you generate a capital gain. On the other hand, if you sell the cryptocurrency for less than you paid initially, you have a capital loss, which can, in most cases, offset other gains.
• Income tax: Earned cryptocurrency on GMO Japan, such as staking, interest, bonuses, and referral rewards, is typically treated as taxable income and must be reported on your tax return.

How to file your GMO Japan taxes

First, you must calculate capital gains and income from all taxable transactions on GMO Japan. When you have this information ready, you can report capital gains and income together with other forms of income, such as employment and dividends, in your annual tax return.

To calculate your capital gains, you must first export a complete history of all transactions made on GMO Japan. Once you have this data, you can calculate your capital gains or losses by determining the price at which you bought the cryptocurrency (your cost basis) and the price at which you sold it (your proceeds). Luckily, Coinpanda can help you with this and generate ready-to-file tax forms quickly and easily.

After downloading your GMO Japan tax statements from Coinpanda, the last step is to report the capital gains and income on your tax return before the deadline. Most countries allow you to self-declare taxes online in 2026, but you can also get help from a professional tax accountant to file taxes for you.
