Summary: Tax System and Mechanism for Overseas Forex Trading Profits from overseas forex trading are treated as miscellaneous income and are subject to comprehensive taxation, where they are combined with other taxable income such as salary income for tax calculation purposes. Let's take a look at the tax system and mechanism that applies to overseas forex trading. There is no obligation to declare only overseas forex losses If you do not make any profit from overseas forex trading throughout the year and incur losses, you are not obligated to declare those losses. A tax return is the procedure of calculating and declaring your taxable income from January 1st to December 31st each year in order to pay the correct income tax. Since income tax is calculated based on taxable income, if you only incur losses in a given year, no income tax will be incurred, and therefore, a tax return is not necessary. If you have made profits, it is better to declare the losses as well If you have other miscellaneous income profits besides overseas forex trading, you should declare your overseas forex losses as well. This is because the less miscellaneous income you have, the less income tax you will have to pay. Income tax is calculated based on the taxable income generated in that year. Therefore, by offsetting profits from other sources with losses from overseas forex trading, you can reduce your taxable income and thus reduce your income tax. Offsetting profits and losses for the same year is called offsetting gains and losses. For example, if you have a loss of 300,000 yen from overseas FX and a profit of 1,000,000 yen from cryptocurrency (which is miscellaneous income), you will calculate income tax on the remaining 700,000 yen in taxable income after offsetting. However, you cannot offset gains and losses with domestic FX brokers. Overseas FX and domestic FX are categorized differently, so you cannot offset gains and losses. Income tax is calculated separately for each income category, so if gains and losses are within the same income category, you can offset them. However, overseas FX is classified as "comprehensive taxation" and domestic FX as "separate taxation," so you cannot offset gains and losses even if they are from the same FX.
