How much profit from overseas forex trading is subject to taxation?

Even if you make a profit from overseas forex trading, you won't be taxed on income up to a certain amount

The amount at which income becomes taxable varies depending on whether you are a salaried employee or a self-employed individual. Below, we will explain in detail how much profit is required to be taxed

  2. Cases where filing a tax return is required
  3. Cases in which filing a tax return is not required
  4. Unrealized gains and losses are not subject to taxation

Profits from overseas forex trading are not eligible for year-end tax adjustments

Year-end tax adjustment: The procedure for settling the amount of withholding tax deducted from salary and bonuses to match the annual tax amount

The amount of withholding tax deducted from your salary and bonuses is an approximate calculation, and the correct annual tax amount is determined through year-end adjustments

Therefore, salaried employees, such as company employees, complete their income tax filing and payment through their company's year-end tax adjustment process

However, year-end tax adjustments cover company salaries and other income, and income other than salary, such as profits from FX trading, is not subject to year-end tax adjustments .

Therefore, remember that if you make a certain amount of profit from FX trading, you will need to file your own tax return

Cases where filing a tax return is required

Below, we will explain the cases in which filing a tax return is required, divided into "salaried employees" and "non-salaried employees."

Salaried employees and other wage earners | Annual profit of 200,000 yen or more

Salaried employees and others who receive a salary are required to pay taxes if their income from overseas forex trading or other side jobs exceeds 200,000 yen per year

The following are the individuals and conditions under which you are required to file a tax return if you have made a profit from overseas forex trading

Target audience- Individuals who receive a salary from their employer, such as company employees, part-time workers, or temporary workers. - Individuals who have income from public pensions, etc
conditionsIf your annual income other than salary exceeds 200,000 yen

If you have income from other sources besides overseas forex trading (such as cryptocurrency trading or affiliate marketing), these will be combined and calculated together

Self-employed individuals, housewives, and other non-salaried individuals | Annual profit of 480,000 yen or more

Individuals who are not employed, such as self-employed individuals or full-time housewives, are required to file a tax return if their annual profits, including income from overseas forex trading, exceed 480,000 yen

Target audienceSelf-employed individuals, housewives, students, unemployed people, and others who do not receive a salary
conditionsIf your total annual income, including income from overseas forex trading, exceeds 480,000 yen

Furthermore, since the basic deduction amount for income tax is 480,000 yen, if your annual profit is less than 480,000 yen, your income will be 0 yen and you will not need to file a tax return

Please note that miscellaneous income other than that from overseas forex trading is also subject to tax filing. If you have income other than overseas forex trading from a side job or other source, please be sure to remember to combine it and file your tax return

Cases in which filing a tax return is not required

The following are cases in which you do not need to file a tax return:

  • Salaried employees: Annual income other than salary is 200,000 yen or less
  • Non-salaried employees: Annual miscellaneous income, including profits from overseas forex trading, is 480,000 yen or less

However, if you make even a single yen profit from overseas forex trading, you are required to declare it to your local municipality for local resident tax purposes. If you file an income tax return, you do not need to declare it to your local municipality, but if you do not file an income tax return, be sure to declare your local resident tax to your local municipality.

The deadline for filing your resident tax return is March 15th of the following year. Failure to file your resident tax return will result in severe penalties, so please be careful not to miss the deadline

  • Penalty for failure to file tax return
  • Late payment penalties
  • Heavy penalty tax
  • criminal punishment

In addition, there is a "tax return exemption system" for pensioners

This system exempts you from filing a tax return if your income from public pensions is 4 million yen or less and you meet certain conditions

The conditions for being eligible for the tax return exemption system are as follows:

  • The total amount of income from public pensions, etc. is 4 million yen or less, and all of the public pensions, etc. are subject to withholding tax
  • Income other than miscellaneous income from public pensions, etc. is 200,000 yen or less

You can determine if you are eligible by looking at your "Withholding Tax Statement for Public Pensions, etc."

If the amount in (1) of your withholding tax statement is 4 million yen or less, and your income other than pensions for that year is 200,000 yen or less, you are not required to file a tax return

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

Please note that taxes are not levied at the time of withdrawal, but rather when the position is closed and the funds are reflected in the account

Will my company find out about my profits from overseas forex trading?

Many people don't want their company to find out they're trading with overseas forex brokers, but if you're making profits that require filing a tax return, there's a high chance your company will find out unless you take precautions

There are two ways to pay resident tax: "special collection," where it is deducted from your salary by your company, and "ordinary collection," where you pay it yourself

It's conceivable that the company's resident tax officer might find out if the amount of resident tax is significantly higher than the taxable income from your main job

How to prevent your company from finding out

There are two ways to keep your overseas forex trading profits a secret:

  • I will pay the local tax on overseas forex trading through ordinary collection
  • I don't tell my colleagues that I have a side job

When filing your tax return , check the box to "pay the local tax on overseas forex trading yourself."

Even if you select "pay yourself," your tax return may be mistakenly processed as special collection, so be sure to check with your city hall after filing your tax return

there's a risk of being reported to the company if you tell a colleague about your side job or if they see your phone notifications

Raising your standard of living, such as by wearing expensive items, increases the risk of being found out by those around you, so be careful not to raise your standard of living too much, even if you are making a certain amount of profit

Points to note when filing tax returns for overseas forex trading

Below, we will introduce three points to keep in mind when filing your tax return for profits from overseas forex trading

  1. Losses cannot be carried forward
  2. Losses from domestic FX trading cannot be offset against profits from domestic FX trading
  3. Even if you don't need to file an income tax return if your profits are low, you will still need to file a local resident tax return

Losses cannot be carried forward

While losses from domestic FX trading can be carried forward, losses incurred from overseas FX trading cannot be carried over to the following year.

If you incur losses in overseas forex trading,
Year 1: Loss of 500,000 yen Year 2: Profit of 1,000,000 yen
Since losses in overseas forex trading cannot be carried forward, taxes will be calculated on the 1,000,000 yen profit in Year 2.
If you incur losses in domestic FX trading,
in the first year you will have a loss of 500,000 yen, and in the second year you will have a profit of 1,000,000 yen.
Since losses from domestic FX trading can be carried forward, you will deduct 500,000 yen from the 1,000,000 yen profit in the second year, and calculate taxes on the remaining 500,000 yen.

Therefore, taxes tend to be higher for overseas forex trading compared to domestic forex trading

The break-even point for overseas and domestic forex trading is approximately 3.3 million yen. However, if you consistently make profits of 4.5 million yen or more after utilizing various deductions, domestic forex trading will likely result in lower taxes

Losses from domestic FX trading cannot be offset against profits from domestic FX trading

Because overseas forex trading and domestic forex trading are categorized differently in terms of income, profits and losses from both cannot be offset against each other

Since income tax is calculated separately for each income category, if you use multiple overseas forex brokers, you can offset profits and losses against each other

If you used three overseas forex brokers in the same year, for example:
Broker A: Loss of 500,000 yen Broker B: Profit of 1,000,000 yen Broker C: Profit of 300,000 yen
The loss of 500,000 yen from Broker A, the profit of 1,000,000 yen from Broker B, and the profit of 300,000 yen from Broker C are offset against each other, and taxes are calculated on 800,000 yen for that year.

Furthermore, income earned from cryptocurrency trading or affiliate marketing is treated as miscellaneous income and can be offset against losses from overseas forex trading

Even if you don't need to file an income tax return if your profits are low, you will still need to file a local resident tax return

Even if your profits from overseas forex trading are small and not subject to income tax, you are still obligated to pay local inhabitant tax if you have made a profit

The local tax rate for overseas forex trading is a flat 10%, while the rate for domestic forex trading is a flat 5%.

Please note that if your profits from overseas forex trading are less than 200,000 yen, you do not need to file a tax return. However, if you have income that cannot be declared through year-end adjustments, you will be obligated to file a local resident tax return

When filing your resident tax return, you will need to submit a document called the "Citizen and Prefectural Resident Tax Return Form" to the local government office. You can download the form from your local government's website and submit it by mail or in person at the counter

Tax-saving strategies for overseas forex trading

Below, we will introduce four tax-saving strategies for overseas forex trading

  1. Record all necessary expenses without fail
  2. Utilize various income tax deductions
  3. Losses from miscellaneous income are offset against each other
  4. Incorporate your business to lower your tax rate

Record all necessary expenses without fail

Profits from overseas forex trading are treated as miscellaneous income, and are calculated by deducting expenses from the profit

While the deductible expenses in overseas forex trading are limited, it's crucial to claim every single expense that qualifies as a tax-saving measure

Examples of expenses that are eligible are as follows:

  • Cost of purchasing a computer or smartphone to be used for trading
  • Communication costs
  • Related book and newspaper expenses
  • Seminar participation fee (including transportation and accommodation expenses)
  • Rent and utilities
  • VPS contract costs for automated trading
  • Transaction fees
  • Equipment costs (stationery, desks, chairs, etc. for business transactions)

Of the above, expenses such as smartphone and computer costs, and rent cannot be fully claimed as business expenses. Only the portion used for overseas forex trading is eligible as an expense, so you need to keep a record of daily usage time when claiming it

Furthermore, with overseas forex trading, high expenses exceeding 100,000 yen must be paid in installments over several years ( depreciation )

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

Utilize various income tax deductions

As a measure to reduce income tax , systems such as "income deductions" have been established.

The Income Tax Act provides for a system of income deductions

This is a system established to adjust the tax burden when calculating income tax, based on social policy requirements, consideration of each taxpayer's personal circumstances, and to guarantee a minimum standard of living. (

Source: National Tax Agency | Outline of Income Deductions)

When income deductions are applied, the amount of income subject to taxation decreases, which in turn reduces the burden of income tax and local taxes

The types of income deductions are as follows:

Additionally, special deduction of up to 650,000 yen for filing a blue return.

The more deductions you can subtract from your taxable income, the lower your tax liability will be. Therefore, be sure to check if you are eligible for any deductions before filing your tax return

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

Offsetting profits and losses: offsetting profits and losses for the same year

By offsetting gains and losses, taxable income decreases, thus reducing income tax

Please note that only miscellaneous income can be offset against profits and losses from overseas forex trading. Domestic forex trading, which falls under a different income category than overseas forex, cannot be offset against profits and losses from overseas forex trading

Incorporate your business to lower your tax rate

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

Offsetting profits and lossesPossiblePossible

Profits from overseas forex trading are subject to progressive taxation, with the highest individual tax rate being 45%, compared to a flat corporate tax rate of 23.2% .

Furthermore, corporate accounts offer significant advantages, such as the ability to deduct more expenses, including executive compensation, and the possibility of carrying forward losses

However, incorporating a business requires initial registration fees and fixed costs such as fees for social insurance and tax accountants. Unless you can consistently generate substantial profits, you won't reap the benefits of incorporation

The break-even point for incorporating a business is approximately 9 million yen. If you cannot consistently generate profits, incorporating is not recommended.

If you are considering incorporating your business, you should make your decision after considering the advantages and disadvantages beyond just tax savings

Can I make hometown tax donations using overseas forex trading?

possible to use the Furusato Nozei (hometown tax donation) system to pay a portion of your taxes to the local government if you make a profit .

Furusato Nozei (Hometown Tax Donation): A system that allows you to donate to your hometown or a municipality you wish to support, and receive local specialty products and other gifts in return

Furusato Nozei (hometown tax donation) can be deducted from your income as a donation deduction, thus reducing your income tax and resident tax for that year

Instead of using the one-stop special exception system that allows you to file your hometown tax donation declaration by mail, you should file a tax return along with your income and expenses from overseas forex trading

Is it possible to offset profits and losses across multiple accounts in overseas forex trading?

If you have multiple accounts with overseas forex brokers, the income classification will be the same, so you can offset profits and losses

Profits from overseas forex trading are classified as miscellaneous income, and profits and losses from cryptocurrency trading and affiliate marketing can be offset against them

You cannot offset profits and losses between domestic and overseas FX trading. Even if you incur a 1 million yen loss in domestic FX and make a 1 million yen profit in overseas FX, you will still be taxed on the profit

Furthermore, you cannot carry forward losses in overseas forex trading

Loss carryforward is a system that allows you to offset losses and profits for up to three years. Even if your profits and losses were negative in the three years prior to last year, you will still be taxed if you make a profit this year

Domestic FX brokers allow loss carryover, so those using both overseas and domestic FX brokers should be careful not to make a mistake

If I'm refused to withdraw funds from an overseas forex broker, will I have to pay taxes?

If your withdrawal is rejected by an overseas forex broker, whether or not it is taxable depends on the circumstances.

  • Transaction history exists → Subject to taxation
  • No transaction history → Tax-exempt

If you have a transaction history, withdrawals are often refused due to errors in the withdrawal process. In this case, since there is still a profit remaining, taxes will be levied

On the other hand, if there is no transaction history, withdrawals are often refused due to the trader's misconduct, and since the profit is not treated as such, it is not subject to taxation

If you have any questions about tax implications when a withdrawal is refused, obtain your transaction history and consult with the tax office or a tax professional

If I don't withdraw the profits I earned from overseas forex trading, do I not have to pay taxes?

Profits earned from overseas forex trading are subject to tax even if they have not yet been withdrawn.

The taxable amount is not the profits you withdraw, but the total profit or loss reflected in your account from January 1st to December 31st

If you want to minimize your taxes, one option is to delay closing any open positions at the end of the year

If you mistakenly believe that you don't need to declare your income because it hasn't been withdrawn, you could face severe penalties depending on the nature and extent of the situation if the tax office finds out. So, be sure to file your tax return

If I file a tax return for my overseas forex trading, will I lose my dependent status?

If you qualify as a dependent and your income, including profits from FX trading, is "480,000 yen or more per year," you will need to file a tax return, and at the same time, you will no longer be considered a dependent

Even if your profit from FX trading is only 100,000 yen, if your total annual income, including income from part-time jobs and other sources, exceeds 480,000 yen, you will no longer be considered a dependent

However, if you are a dependent under social insurance, you will be eligible for dependent status for two consecutive years if your income is only temporarily increased

While overseas forex trading offers many advantages over domestic forex, such as greater leverage flexibility and more generous bonuses, it also has a progressive tax system based on comprehensive taxation, meaning the tax burden increases as income rises. Furthermore, it's important to note that preferential treatments like loss carryforward and separate taxation, as available with domestic forex, are not applicable. Additionally, tax treatment can vary depending on individual trading circumstances, so it's best to consult with the tax office or a specialist if you have any questions. Consider tax-saving strategies and the impact on dependents and resident taxes, and strive for planned trading and tax preparation
