Unrealized gains and losses are not subject to taxation

Only realized gains and losses are subject to taxation; unrealized gains and losses are not. Realized gains and losses refer to the profits and losses that have been confirmed by closing out held positions.

Please note that swap points, which are received when adjusting for the interest rate difference between the currencies being bought and sold, are subject to taxation when they are received and reflected in your account

However, cashback is subject to taxation

on FX trading include cashback received from FX brokers as part of promotions such as opening an account or making a deposit.

Generally, cashback is considered temporary income, and a special deduction of 500,000 yen is available

Therefore, if the remaining amount, including other temporary income, is 500,000 yen or less, it will not be subject to taxation.

Calculation formula for temporary income
: Total temporary income - Total expenses - Special deduction (500,000 yen) = Amount of temporary income

However, the amount actually subject to taxation is half of the amount of temporary income

Furthermore, since temporary income is subject to comprehensive taxation, the tax is calculated by adding half the amount of temporary income to other income such as salary income

Based on profits including half of the amount of temporary income, salaried employees are required to file a tax return if their total profit exceeds 200,000 yen, and non-salaried employees are required to file a tax return if their total profit exceeds 480,000 yen

Please note that losses cannot be carried forward

Losses incurred in overseas forex trading cannot be carried forward and offset against profits in subsequent years.

  • If you use two overseas forex brokers in the same year:
    Broker A: Loss of 300,000 yen Broker B: Profit of 1,000,000 yen

Company A's loss of 300,000 yen and Company B's profit of 1,000,000 yen are offset, and taxes are calculated on 700,000 yen for that year

On the other hand, losses incurred in domestic FX trading can be carried forward for up to three years, allowing you to deduct the previous year's losses from your income in the following year

  • If you incur losses in overseas forex trading:
    Year 1: Loss of 300,000 yen Year 2: Profit of 1,000,000 yen

Since overseas forex trading does not allow loss carryforward, taxes will be calculated on the 1 million yen in the second year

  • If you incur losses in domestic FX trading:
    Year 1: Loss of 300,000 yen Year 2: Profit of 1,000,000 yen

Since losses from domestic FX trading can be carried forward, taxes are calculated on the remaining 700,000 yen after deducting 300,000 yen from the 1 million yen profit in the second year

Be aware that tax laws differ between overseas and domestic forex trading, so you cannot carry forward losses to subsequent years

Will my company find out about my overseas forex trading? Or will they not?

In conclusion, if you don't take precautions, there's a high probability that your company will find out

Since salaried employees have their year-end tax adjustments handled by their companies, the companies are aware of their tax liability. If your resident tax increases while your salary remains the same, it may raise suspicion of a side job (such as overseas forex trading). This increase in resident tax is the most common way for your company to find out .

Furthermore, if you make a large profit from overseas forex trading and your sense of money changes, your colleagues might find out about your side job

Measures to prevent your company from finding out about your overseas forex trading

  • Change the method of collecting resident tax to "ordinary collection"
  • Don't raise your standard of living too high
  • Keep your income below 200,000 yen
  • Record all expenses without fail

If you don't want your overseas forex trading to be discovered, to choose "ordinary collection" for your resident tax . If you choose "special collection," your resident tax will be deducted from your salary, increasing the risk of your company finding out.

Furthermore, for salaried employees, if you have income of 200,000 yen or more in addition to your salary, you are required to file a tax return if your income after deducting expenses is 200,000 yen or less, you are not required to file a tax return . Expenses such as the cost of a computer and desk used for FX trading, communication fees, and book costs can be claimed as business expenses.

However, high-cost items such as computers and smartphones must be accounted for over several years ( depreciation ). It is recommended to avoid purchasing expensive computers costing over 100,000 yen.

Since expenses such as communication costs and rent can only be claimed for the amount actually used, not the full amount, be sure to keep a record of how long you use them

Cost of purchasing a smartphone or computerDistribution method
Less than 100,000 yenLump-sum accounting
100,000 yen or more but less than 200,000 yenAccounted over three years
Over 200,000 yenAccounted over four years

Losses from miscellaneous income are offset against each other

If you have gains or losses from miscellaneous income other than overseas forex trading, you should offset those gains and losses against each other. By offsetting gains and losses, the profits and losses from miscellaneous income will be offset, reducing your taxable income and thus lowering your income tax. Here are two examples of offsetting gains and losses between overseas forex trading and miscellaneous income.

  1. If you have a profit of 1.5 million yen from overseas forex trading and a loss of 1 million yen from cryptocurrency trading, you will calculate income tax on the remaining 500,000 yen in taxable income after offsetting the losses
  2. If you have a profit of 1.5 million yen from overseas forex trading and a loss of 1 million yen from cryptocurrency trading, you will calculate income tax on the remaining 500,000 yen in taxable income after offsetting the losses

Only miscellaneous income can be offset against profits and losses from overseas forex trading. Be aware that profits and losses from domestic forex trading, which falls under a different income category than overseas forex trading, cannot be offset

Adjust profits to stay within the dependent allowance limit or to an amount that does not require reporting

By keeping your profits from overseas forex trading within the limits of being a dependent or below the amount required for filing a tax return, you can reduce your tax burden and lower your tax liability

If your profits from overseas forex trading increase significantly, you may lose your dependent status and be unable to receive dependent deductions, or you may need to file your own tax return and incur tax obligations

If you are claiming a dependent deduction or do not need to file a tax return, your taxable income should be within the following amounts

  • To claim the spousal deduction,
    your taxable income must be within 480,000 yen.
  • To claim the special spousal deduction,
    your taxable income must be between 380,000 yen and 1,330,000 yen.
  • Cases where filing a tax return is not required
    : Salaried employees... Annual profits must be within 200,000 yen.
    Non-salaried employees... Annual profits must be within 480,000 yen.

Sometimes, earning more is more advantageous than suppressing profits for tax-saving purposes, so consider this carefully

Incorporate your business to lower your tax rate

Incorporating your business can lower your tax rate, leading to significant tax savings

While profits from overseas forex trading are subject to progressive taxation , with a top tax rate of 45% for individuals, the corporate tax rate is a flat 23.2%. Furthermore, there are significant advantages such as an increased number of items that can be used as expenses, such as executive compensation, and the ability to carry forward losses.

However, incorporating a business requires initial registration fees and fixed costs such as fees for social insurance and tax accountants. Furthermore, executive compensation received from the corporation must adhere to certain rules, such as being a regular, fixed salary, to be deductible as an expense

In other words, you will no longer be able to withdraw money freely . If you are considering incorporating your business in the future, be sure to consider the advantages and disadvantages beyond tax savings before making a decision.

Q&A regarding tax savings in overseas forex trading

Here are four frequently asked questions regarding tax savings in overseas forex trading

Q. Are there any loopholes in paying taxes?

Japanese tax authorities are supposed to be able to track income generated overseas through systems such as overseas remittance reports and CRS (Common Reporting Standard), so there are no loopholes in tax collection.

A Report of Overseas Remittances is a notification sent to the tax office when profits earned from overseas forex trading are deposited into a domestic account for use in Japan. The Critical Scheme (CRI) is a system designed to prevent tax evasion and avoidance using foreign financial institutions

Profits earned from overseas forex trading are also subject to taxation in Japan, so failing to file a tax return and pay taxes constitutes tax evasion.

If you fail to declare your income, you will have to pay an additional penalty tax for failure to file. This penalty tax is 15% to 20% of the original tax amount, so you will have to pay extra tax. Also, if you file or pay after the deadline, you may be charged a late payment penalty

Furthermore, if there is serious negligence such as concealing income, an additional heavy penalty tax of 35% to 40% must be paid. Since profits generated from overseas forex trading are also known to the Japanese tax authorities, be sure to file your tax return properly if you make a profit.

Q. Do I need to file a tax return for losses?

If your overseas forex trading results in a loss at the end of the year, you are not obligated to declare that loss on your tax return

However, if you have other miscellaneous income in addition to overseas forex trading, you should offset those losses against your overseas forex trading income when filing your tax return. This is because offsetting your overseas forex losses against your other miscellaneous income will reduce your taxable income and thus your tax burden.

For example, if you have a loss of 300,000 yen from overseas forex trading and a profit of 1,000,000 yen from cryptocurrency (which is considered miscellaneous income), you would calculate income tax on the remaining 700,000 yen in taxable income after offsetting the losses. If you don't offset the losses, you would have to pay taxes on the 1,000,000 yen in cryptocurrency profit, resulting in paying 300,000 yen more in taxes

Q. How will I pay my resident tax?

Profits from overseas forex trading are also subject to local inhabitant tax (income-based tax) . Since profits from overseas forex trading are subject to comprehensive taxation, the local inhabitant tax (income-based tax) rate is 10%.

Income-based tax refers to local resident tax calculated based on income earned from January 1st to December 31st of the previous year, similar to income tax

Furthermore, the local inhabitant tax (income-based) on domestic FX trading, which is subject to separate taxation, is 5%. In addition, the local inhabitant tax (per capita levy) is a fixed amount of 5,000 yen (3,500 yen for municipal tax and 1,500 yen for prefectural tax), regardless of income

Are computers and smartphones

Computers and smartphones used for overseas forex trading can be claimed as business expenses

However, the amount you can deduct as an expense differs depending on whether you use your PC or smartphone solely for overseas forex trading or for personal use as well. If you use your PC or smartphone exclusively for overseas forex trading, you can deduct the full amount as an expense

However, if you use it for both personal and business purposes, you must calculate the usage ratio, and only the amount used for overseas forex trading is eligible as a business expense. In addition, communication costs such as internet access can also be claimed as expenses . If you use it for both personal and business purposes, calculate the usage time and include it as an expense.
