Tax rules for overseas forex trading

If you make a profit above a certain amount from overseas forex trading, you are required to file a tax return

Furthermore, the tax system differs significantly from domestic FX, including the inability to carry forward losses

The following explains in detail the rules regarding taxes on overseas forex trading

1. Taxes on overseas forex trading are subject to comprehensive taxation
2. Losses from overseas forex trading cannot be carried forward
3. Losses from domestic FX trading cannot be offset against profits from domestic FX trading

Taxes on overseas forex trading are subject to comprehensive taxation

The taxation method for FX profits differs between overseas FX and domestic FX;overseas FX is subject to "comprehensive taxation," while domestic FX is subject to separate taxation based on declaration.

Comprehensive taxation calculates income tax by aggregating various types of income. On the other hand, separate taxation is a taxation method in which income tax is calculated separately from other income

Furthermore, while the tax rate for domestic FX is a flat 20.315% including the special reconstruction income tax,overseas FX employs a progressive tax system where the tax rate increases as the amount of income increases.

Overseas forex trading can result in income tax of up to 45% (approximately 55% when combined with local tax of 10%), meaning the larger your profits, the heavier your tax burden becomes

Taxable income	tax rate	Deduction amount
From approximately $6.25 to approximately $12,181	5％	approx. $0.00
From approximately $12,188 to approximately $20,619	10％	approx. $609.38
From approximately $20,625 to approximately $43,431	20％	approx. $2,672
From approximately $43,438 to approximately $56,244	23％	approx. $3,975
From approximately $56,250 to approximately $112,494	33％	approx. $9,600
From approximately $112,500 to approximately $249,994	40％	approx. $17,475
Approximately $250,000 or more	45％	approx. $29,975

The break-even point for tax burden between overseas and domestic forex trading is approximately $30,000 in taxable income, but depending on the amount of expenses claimed, overseas forex trading may be tax-lower even above that amount. Detailed calculations are explained in the Complete Guide to Overseas Forex Taxes

How much tax do you have to pay on overseas forex trading? Tax rates, calculation methods, and how to file your tax return [Supervised by a tax accountant]

Losses from overseas forex trading cannot be carried forward

While domestic FX trading allows you to carry forward losses, overseas FXtrading does not.

Loss Carryforward: A system that allows you to carry forward losses from the current year to the following year and offset them against profits. Even if you make a large profit in the following year, you can expect tax savings by offsetting it against the losses from the previous year

It's important to note that if you incur significant losses after the year ends and are unable to pay your taxes, it will be considered tax evasion, and you will be subject to heavy penalties. Therefore, if you end the year with a profit and need to file a tax return, it is recommended that you withdraw the amount of tax you owe in advance

Do I need to file a tax return for losses from overseas forex trading? This article explains how to offset gains and losses and how to fill out the tax return form

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

Overseas forex trading, which is subject to comprehensive taxation, and domestic forex trading, which is subject to separate taxation, are classified as different income categories, so profits and losses cannot be offset against each other

Therefore, even if you make a profit of approximately $6,250 in overseas forex trading and a loss of approximately $3,125 in domestic forex trading, you will still need to pay taxes on approximately $6,250

Loss offsetting: A system that allows profits and losses incurred in the same fiscal year to be offset against each other

	Overseas FX	Domestic FX
Tax classification	Comprehensive taxation	Separate taxation upon declaration
tax rate	5％〜45％	20.315％
Loss carryforward	Not possible	Possible
Offsetting profits and losses	Only permissible within the same miscellaneous income category	Only permissible in futures trading, etc

However,possible to combine and declare profits and losses that fall under the same category of miscellaneous income. Examples include profits and losses from other overseas forex brokers, cryptocurrency forex trading, and affiliate income.

When using both overseas and domestic forex trading, it's important to thoroughly understand the differences in tax rates and tax classifications

Key points to know about expenses for overseas forex trading

There are five key points to keep in mind regarding expenses for overseas forex trading:"Record any profits without fail," "The final decision on whether to approve them rests with the tax office," "Only transaction-related expenses are covered," "Expenses cannot be carried over to the following year," and "The categoriesare almost the same as for domestic forex trading."

Let's review each item to ensure you can correctly account for your expenses when filing your tax return

1. If you make a profit from overseas forex trading, it's more tax-efficient to deduct it as an expense
2. Whether or not to claim expenses is at your own discretion
3. Only transaction-related expenses can be deducted
4. Expenses cannot be carried over to the following year
5. The items that can be claimed as expenses are almost the same as those for domestic FX trading

If you make a profit from overseas forex trading, it's more tax-efficient to deduct it as an expense

While taxes are levied on profits exceeding a certain amount from overseas forex trading, claiming expenses when filing your tax return can be highly effective in reducing your tax burden

The reason is that while domestic FX trading has a flat tax rate of 20.315%, overseas FX trading employs a "progressive tax" system where the tax rate increases as profits increase

If you have few expense items, the amount of tax savings will be minimal, but themore expenses you claim, the more you can reduce your taxes.

While the specific items that qualify as deductible expenses are not publicly disclosed, you can expect tax savings by including all the expenses listed in the following section

7 Tax-Saving Strategies for Overseas Forex Trading: Explaining How to Reduce High Taxes and the Truth About Loopholes

Whether or not to claim expenses is at your own discretion

Many people understand that "transaction fees" and "indicator costs" related to FX trading can be deducted as necessary expenses, but it is also possible to partially claim expenses such as electricity bills and rent

However,whether all expenses are approved is at the discretion of the tax office, and which expense categories are approvedis not publicly disclosed.

Therefore, it is up to your own judgment to decide which expenses to include and to what extent. If you have any questions about expenses, it would be wise to consult with a tax accountant or other professional

Only transaction-related expenses can be deducted

When filing your tax return for overseas forex trading, only transaction-related expenses can be deducted

For example, the following types of expenses are often approved by the tax authorities

• Transaction fees
• Indicator costs
• Books related to FX

However, expenses unrelated to FX, such as transportation costs, book expenses, and food expenses, are not deductible. Even if you try to claim unrelated expenses thinking "I won't get caught," investigators will scrutinize not only the amount but also the itemized details, so you will definitely get caught

without proper considerationcan result in severe penalties, so it's important to implement tax-saving measures in accordance with the law.

Expenses cannot be carried over to the following year

You cannot carry over expenses to the following year and use that to reduce your taxes, simply because "profits were low this year."

Expenses related to FX trading, such as books, paid for during the year must be recorded as expenses for that year. As an exception, expenses exceeding approximately $625.00 must be depreciated and spread over several years

The items that can be claimed as expenses are almost the same as those for domestic FX trading

The criteria for what constitutes a deductible expensethe same for both overseas and domestic forex trading: "expenses related to trading." The expense items and household expense allocation ratios introduced in this article can be used in almost the same way when filing tax returns for domestic forex trading.

The difference lies not in the expenses themselves, but in the method of calculating taxes. For overseas FX trading, you enter your income and necessary expenses in the "miscellaneous income" column under comprehensive taxation, while for domestic FX trading, you enter them in the "miscellaneous income, etc., related to futures transactions" column under separate taxation

Furthermore, with overseas forex trading, which is subject to progressive taxation, the tax rate increases with higher income. Therefore,even with the same amount of expenses, the tax-saving effect is greater for those with a higher tax rate.

What expenses can be deducted when trading overseas forex?

From here, we'll introduce what you can deduct as expenses when trading overseas forex. First, let's look at an overview diagram

This chapter will explain the items marked "Full Amount ○" one by one. In principle, all of these items can be fully expensed

1. Transaction fees
2. Cost of purchasing a PC or smartphone
3. Consumables/equipment fees
4. Books on overseas forex trading
5. Seminar participation fees, transportation costs, and accommodation costs related to FX
6. VPS contract costs for automated trading
7. Purchase cost of EAs and indicators
8. Fees for hiring a tax accountant
9. Entertainment expenses
10. Interest on debt

Transaction fees

Transaction fees incurred when placing an order can be recorded as expenses

alsoeligible expenses. However, spreads are included in profit and loss and therefore cannot be claimed as expenses.

Here's how to check trading fees in MT4 and MT5:

1. Open the MT4/MT5 terminal screen
2. Select the "Account History" tab and right-click
3. Click "Display Column" and select "Fees" to see the fees for each transaction

Cost of purchasing a PC or smartphone

The cost of purchasing a computer or smartphone, as well as other items such as tablets and monitors, can be claimed as necessary business expenses

However, when accounting for the cost of purchasing a computer or smartphone,if it is used for purposes other than business transactions, you must calculate the usage percentage and declare it.

[Example]If you have a computer that costs approximately $562.50 and your trading time per day is 3 hours, then
approximately $562.50 × (3 hours ÷ 24 hours) = approximately $68.75

Furthermore, if the purchase cost of a computer or smartphone exceeds approximately $625.00, the expense must be spread over multiple years (depreciation)

Cost of purchasing a PC or smartphone	Depreciation rate	Depreciation period
Approximately less than $625.00	100%	Lump-sum accounting
Approximately $625.00 or more, and less than approximately $1,250	33.3%	Accounted over three years
Approximately $1,250 or more	25%	Accounted over four years

Consumables/equipment fees

The following consumables can also be recorded as expenses:

• Notebook
• pen
• chair
• desk
• ink
• sticky note
• printer

Even if each individual expense is small, the total amount can add up over a year.Keep receipts for supplies and equipment instead of throwing them away.

Furthermore, in the event of a tax audit, you may be asked to submit these records to verify whether you have actually kept proper transaction records

Books on overseas forex trading

In FX trading, daily study and information gathering are essential

You can also claim expenses such as books, newspapers, and email newsletters related to FX as business expenses

However, please note that general newspapers unrelated to the transaction are not eligible as expenses

If the document contains information related to FX trading, it's a good idea to keep it as evidence

Seminar participation fees, transportation costs, and accommodation costs related to FX

If you attend a seminar on FX trading, you can claim not only the participation fee but also transportation and accommodation expenses as business expenses

When staying at a hotel, be sure to get a receipt. Fortransportation expenses (Suica/PASMO), you can print out your usage history at the station.However, please note that the number of entries that can be printed varies depending on the type of electronic money.

Types of electronic money	Number of printable items	Printable period
Suica	100 items	26 weeks
PASMO	20 items	26 weeks
ICOCA	20 items	26 weeks

VPS contract costs for automated trading

Many people likely subscribe to a VPS (Virtual Private Server) to run automated trading 24 hours a day, 365 days a year

Contract fees with server companies, both domestic and international, are deductible expenses.Monthly usage fees can also be included.

However, some overseas forex brokers offer free VPS access if certain conditions are met, so be sure to check with your chosen broker before signing a contract to see if they offer free VPS

Purchase cost of EAs and indicators

The cost of purchasing MT4/MT5 indicators and automated trading software is also eligible as a necessary expense

MT4 and MT5 indicators can be purchased using MQL5, andif you want to claim them as expenses, saving the purchase history screen will allow you to submit it as evidence in the event of a tax audit.

Fees for hiring a tax accountant

Expenses such as consultations regarding taxes and fees for filing tax returns can also be claimed as business expenses

Additionally, transportation costs and telephone charges incurred when visiting the office for a free consultation are also deductible expenses

Since hiring a tax accountant to file your tax return typically costs around $312.50 to $625.00, claiming this service can result in significant tax savings

While preparing your tax return yourself can save you money, it's safer to hire a tax accountant and have them handle the expenses, ensuring accuracy

Entertainment expenses

, such as information exchange meetings with fellow FX traders or social gatherings after seminars,may be deductible as entertainment expenses.

However, meals with friends unrelated to FX or meetings that are merely nominal are not deductible expenses. Entertainment expenses are a category where explanations of their relevance to trading are particularly likely to be required, so keep a record of "when, with whom, and for what purpose" and keep the receipts. If you are unsure, consult a tax accountant

Interest on debt

If you use a loan from a consumer finance company as collateral,you can deduct the interest paid on the loan as an expense.

However, since taking out loans to trade FX is extremely risky, it is recommended to trade only within the limits of your surplus funds

What percentage of expenses can be claimed as household expenses when trading overseas forex?

Some expenses that can be deducted in overseas forex trading can only be claimed in part, not in full

This section outlines the categories and percentages for which household expenses can be allocated. The following are guidelines:

1. PC and smartphone communication costs: 10-20%
2. Electricity costs: 5-10%
3. Rent: 5-15%

PC and smartphone communication costs: 10-20%

You can claim approximately 10-20% of your computer and smartphone communication expenses as business expenses

[Example]If you use your smartphone for 6 hours for personal use and 2 hours for business use per day, and your
total daily usage time is 8 hours, then 2/8 × 100% = 25%.　
You can claim 25% of your communication expenses as a business expense.

The calculation method for PC communication costs is the same. However, please note that the cost of the smartphone itself is not included in communication costs and should be treated separately as a purchase cost . Only the monthly communication fee is included

Electricity costs: 5-10%

Computer usage time (and the associated electricity costs) is also highly likely to be partially recognized as a business expense

Aim for a percentage of around 5-10% andrecord and report your computer usage time.

Since the amount of electricity used for transactions is small compared to the total amount of electricity used in the house, be aware that if it exceeds 20%, you may be subject to a tax audit

Rent: 5-15%

When claiming rent as a business expense, a good guideline is to aim for 5-15%

There are two methods for calculating the ratio: one is to calculate it based on FX trading hours , and the other is to calculate it based on the ratio of the workspace area

If calculating based on trading hours, assuming a trading day of 3 hours, the percentage is calculated as follows

3 hours ÷ 24 hours × 100 = 12.5%

If we calculate based on the area of ​​the workspace, assuming the workspace occupies 20% of the total house area and the rent is approximately $625.00, the calculation would be as follows:

approx. $625.00 × 20% = approx. $125.00 ← Can be claimed as an expense

Rent for an entire house that you use on a regular basis cannot be claimed as a business expense. However, if you use the entire premises as an office for FX trading, you can claim the entire rent as a business expense

Furthermore, if you own your home,the property tax paid four times a year is also deductible as an expense. The calculation of the percentage is the same as for rental properties, calculated from the area of ​​the room used for FX trading.

Tax differences based on expense amounts

Overseas forex trading employs a progressive tax system, where the tax rate increases as your income rises

The income tax rate is up to 45%, and the local tax on overseas forex trading is a flat 10%, so you could end up paying up to 55% in taxes

Taxable income	tax rate	Deduction amount
From approximately $6.25 to approximately $12,181	5％	approx. $0.00
From approximately $12,188 to approximately $20,619	10％	approx. $609.38
From approximately $20,625 to approximately $43,431	20％	approx. $2,672
From approximately $43,438 to approximately $56,244	23％	approx. $3,975
From approximately $56,250 to approximately $112,494	33％	approx. $9,600
From approximately $112,500 to approximately $249,994	40％	approx. $17,475
Approximately $250,000 or more	45％	approx. $29,975

Below,assuming an annual income of approximately $31,250 (income from overseas forex trading only), we will calculate and present the differences in tax amounts based on various necessary expenses.

*The tax rate of 20% from the tax rate table + a quick calculation deduction of approximately $2,672 is applied. Income deductions are limited to the basic deduction only (income tax approximately $3,938, local tax approximately $2,688 / for fiscal years 2025 and 2026), and the flat-rate portion of local tax and rounding of amounts less than approximately $0.63 are omitted for this approximation (as of August 2026 -National Tax Agency | Basic Deduction).

Assuming an income of approximately $31,250 and necessary expenses of approximately $625.00

If your annual income is approximately $31,250,to an income tax rate of 20% (with a quick deduction) + local taxes of 10% + special reconstruction income taxof 2.1%.

[Income Tax Calculation Formula]
approx. $31,250 (Annual Income) - approx. $3,938 (Basic Deduction) - approx. $625.00 (Necessary Expenses) = approx. $26,688 (Taxable Income)
approx. $26,688 × 20% - approx. $2,672 (Quick Deduction) = approx. $2,666

[Calculation formula for local tax]
approx. $31,250 - approx. $2,688 (basic deduction) - approx. $625.00 (necessary expenses) = approx. $27,938
approx. $27,938 × 10% = approx. $2,794

[Calculation formula for the special reconstruction income tax]
approx. $2,666 (income tax amount) × 2.1% = approx. $55.98

[Total tax payment]
approx. $2,666 (income tax) + approx. $2,794 (resident tax) + approx. $55.98 (special reconstruction income tax) = approx. approx. $5,513

Assuming an income of approximately $31,250 and necessary expenses of approximately $1,875

[Income Tax Calculation Formula]
approx. $31,250 (Annual Income) - approx. $3,938 (Basic Deduction) - approx. $1,875 (Necessary Expenses) = approx. $25,438 (Taxable Income)
approx. $25,438 × 20% - approx. $2,672 (Quick Deduction) = approx. $2,416

[Calculation formula for local tax]
approx. $31,250 - approx. $2,688 (basic deduction) - approx. $1,875 (necessary expenses) = approx. $26,688
approx. $26,688 × 10% = approx. $2,669

[Calculation formula for the special reconstruction income tax]
approx. $2,416 (income tax amount) × 2.1% = approx. $50.73

[Total tax payment]
approx. $2,416 (income tax) + approx. $2,669 (resident tax) + approx. $50.73 (special reconstruction income tax) = approx. approx. $5,131

Assuming an income of approximately $31,250 and necessary expenses of approximately $3,125

[Income Tax Calculation Formula]
approx. $31,250 (Annual Income) - approx. $3,938 (Basic Deduction) - approx. $3,125 (Necessary Expenses) = approx. $24,188 (Taxable Income)
approx. $24,188 × 20% - approx. $2,672 (Quick Deduction) = approx. $2,166

[Calculation formula for local tax]
approx. $31,250 - approx. $2,688 (basic deduction) - approx. $3,125 (necessary expenses) = approx. $25,438
approx. $25,438 × 10% = approx. $2,544

[Calculation formula for the special reconstruction income tax]
approx. $2,166 (income tax amount) × 2.1% = approx. $45.48

[Total tax payment]
approx. $2,166 (income tax) + approx. $2,544 (resident tax) + approx. $45.48 (special reconstruction income tax) = approx. approx. $4,750

With expenses of approximately $625.00 and approximately $3,125, there is a difference of approximately $762.50 in the amount of tax payable . In this example (in the 20% tax rate bracket), for every approximately $62.50 increase in expenses, taxes will be reduced by approximately $18.75 . The tax-saving effect of approximately $0.01 becomes greater for those with higher tax rates, so be sure to check that you haven't missed any expenses.

Points to note when claiming expenses in overseas forex trading

This section will explain important points to keep in mind when claiming expenses on your tax return

To ensure you file your tax return correctly, make sure you understand the following points

1. In some cases, expenses may not be approved
2. High expenses must be depreciated
3. Keep receipts and invoices for at least 5 years
4. Spreads are not eligible for expense deductions
5. If expenses are high relative to profits, it may raise suspicions of tax evasion

In some cases, expenses may not be approved

While individuals are free to decide which expenses to include and how much they qualify as expenses, the final decision on whether or not to recognize them rests with the tax office

The criteria for determining whether an expense is related to FX trading and whether the percentage is reasonable will be used, and in some cases, the expense may not be approved.

Be aware that including expenses unrelated to FX trading, or fully deducting expenses such as rent (which can be partially deducted), could trigger a tax audit

High expenses must be depreciated

Expenses exceeding approximately $625.00, such as the cost of purchasing a smartphone or computer, must be depreciated

Depreciation is the process of allocating the amount spent on acquiring a depreciable asset as a necessary expense for each year using a specific method.

(Source:National Tax Agency | Overview of Depreciation)

The depreciation period varies depending on the expense;if it is approximately $1,250 or more, it must be expensed over four years.

Cost of purchasing a PC or smartphone	Depreciation rate	Depreciation period
Approximately less than $625.00	100%	Lump-sum accounting
Approximately $625.00 or more, and less than approximately $1,250	33.3%	Accounted over three years
Approximately $1,250 or more	25%	Accounted over four years

Therefore, even if you purchase a smartphone or computer costing approximately $625.00 or more at the end of the year in the hope of tax savings, you are unlikely to gain significant benefits

Keep receipts and invoices for at least 5 years

Receipts and invoicesmust be kept as evidence for a minimum of five years. (Seven years for those filing blue-form tax returns.)

In addition, the following documents have also been accepted as evidence

• Bank account transfer statement
• Credit card statement
• Screenshots on smartphones and computers

Even if you purchase indicators online or subscribe to a VPS, saving the details on your computer will allow you to submit them as evidence if a tax audit occurs

As a point of caution, when storing receipts or invoices, simply keeping them as they are may not provide sufficient information. Therefore, be sure to check that the following information is clearly stated

• Payment date
• Payment amount
• address
• Proviso

Furthermore,if the requirements are met, it is possible to store supporting documents such as receipts as electronic data(Electronic Bookkeeping Law).

For further details , please visit the " Special Site for the Electronic Bookkeeping System " on the National Tax Agency's website

Spreads are not eligible for expense deductions

While "transaction fees" incurred when placing a trade order are recognized as expenses, spreads are not

because the spread is included in the buying and selling rate and is not considered a commission.

Other fees that qualify as expenses include deposit fees, withdrawal fees, and account maintenance fees

Please be careful, as including the spread as an expense will result in double counting

If expenses are high relative to profits, it may raise suspicions of tax evasion

If expenses are excessively high relative to profits, it may raise suspicions of fraud and lead to a tax audit

In some cases, this could be considered tax evasion, and severe penalties could be imposed

While there is no upper limit on expenses,you should account for expenses in accordance with the law, within the limits of being able to clearly present evidence.

If you want to reduce your taxes with overseas forex trading, incorporating your business is one option

While it's important to "accurately record all expenses" when it comes to tax-saving strategies for overseas forex trading, those with high annual incomes may also consider "incorporating" their business, which can offer even greater tax benefits

While the income tax rate for overseas forex trading is a progressive tax ranging from 5% to 45%,if you incorporate your business, the corporate tax ratewill be a flat 23.2%.

If your income is low, there's no problem, but as your income increases, your income tax will become higher than your corporate tax

Below, we will explain the advantages of incorporating your business and the break-even point at which you should consider incorporating

Incorporating your business increases the number of expenses you can deduct

Incorporating your overseas forex trading business increases the number of deductible expenses, leading to greater tax savings

The following items can be claimed as expenses once you incorporate your business:

• Executive compensation
• rent

• Tax burden reduction (a flat rate of 23.2%)
• You can join the Employees' Pension Insurance
• Losses can be carried forward for up to 10 years
• It is possible to offset profits and losses with other businesses

In addition to significant tax benefits, the trading conditions for FX are almost the same as for individual accounts, allowing you to trade using your usual methods.The only major difference between a corporate account and an individual accountis the "tax system," so incorporating might be a good option for those with high annual profits.

The break-even point for incorporation is "annual income of approximately $56,250"

The break-even point for incorporating an overseas forex trading business is an annual income of approximately $56,250
