The government believes that the My Number system will improve the convenience of administration and daily life for citizens, and contribute to the realization of a fair and just society.

The purpose of My Number	overview
Realizing a fair and just society	To efficiently grasp income and the status of orders for administrative services

Improving convenience for citizens	To reduce the number of required documents and simplify administrative procedures

The improved convenience brought about by My Number specifically means that managing income and taxes becomes easier. It's also being used to simplify government procedures and streamline local government operations.

Regarding securities companies and FX services, it is said that this helps prevent tax evasion on profits earned from trading and also helps avoid problems such as identity theft and fraudulent activities

You do not need to submit your My Number when opening an account with an overseas forex broker

Now, let's get to the main point. Is it necessary to submit your My Number (Japanese individual identification number) when trading forex overseas?

To put it simply, overseas forex brokers do not require you to submit your My Number (social security number).

As we have seen, the My Number system is a system within Japan. It is used by domestic financial service providers to understand "how much income an individual is earning." Since overseas FX brokers are not Japanese companies, a My Number is not required when opening an account

Please note that you can use your My Number Card as proof of identity or address when opening an overseas forex account

Even with overseas forex trading, you need to submit your My Number when filing your tax return . While you don't need to submit your My Number when opening an overseas forex account, you are required to submit it when filing your tax return for income earned from overseas forex trading. In any case, you will need your My Number .

Submission of My Number (Social Security Number) is mandatory for domestic FX brokers

• Overseas Forex Trading → No My Number (Social Security Number) is required when opening an account.
• Domestic Forex → Submission of My Number (Social Security Number) is mandatory when opening an account.

In domestic FX trading, the Financial Services Agency mandates the submission of your My Number (Social Security Number) . This My Number is required not only for FX trading, but also when opening accounts with securities companies and banks.

Furthermore, even customers who had accounts before the introduction of the My Number system will be required to submit their My Number. Even if they do not have a My Number card, they will need to submit either a resident registration certificate that includes their My Number or a My Number notification card

Why is submitting your My Number required when using domestic FX brokers?

Submitting your My Number (Social Security Number) is mandatory for domestic FX brokers. FX brokers are obligated to issue payment statements detailing "who received how much" and report this information to the government. They cannot provide financial services without obtaining your My Number.

Having a My Number meansFX traders have a system in place that prevents them from falsifying information about their profits and incomeIt is as it is

The National Tax Agency uses these payment statements issued by FX brokers to track the income earned by each trader. If there are any suspicious points in each trader's declaration, they conduct a thorough investigation to determine if there is any suspicion of tax evasion

Forex trader's tax evasion case

, let's take a quick look at some past tax evasion cases

Housewife evades taxes with 400 million yen in profits! – Yukiko Ikebe

One of the most famous cases of tax evasion related to FX trading the 2007 case of Yukiko Ikebe, a housewife from Setagaya Ward who was indicted . Ikebe earned approximately 470 million yen in FX profits over four years, and allegedly evaded 139 million yen in income tax.

Following this incident, Ms. Ikebe became extremely famous under the name "Mrs. Watanabe," and since then has been conducting publishing books

Billionaire trader who was living it up at Roppongi Hills caught for tax evasion! - By Kiyoharu Isogai

Another example of tax evasion related to FX trading the "Roppongi Hills Isogai Tax Evasion Case," in which Mr. Isogai was exposed in 2009 for evading 160 million yen in taxes .

Mr. Isogai, who earned 450 million yen from FX trading, was living in the luxury apartment building Roppongi Hills at the time. However, when his tax evasion was discovered, he suddenly found himself burdened with 330 million yen in debt due to heavy penalties and other charges

To avoid such massive tax evasion, the submission of My Number (social security number) is strictly required for domestic FX trading

What documents are required instead of My Number when using an overseas forex broker? 

we will explain the documents required in place of your My Number when opening an account with an overseas forex broker

The following two types of documents are required:

• Identity verification documents issued by public institutions
• Resident registration documents

We will explain these two types of documents in detail, so please refer to this information if you are considering opening an overseas forex account

Identity verification documents issued by public institutions

Opening an overseas forex account requires identification documents issued by a public institution

acceptable identification documents include the following:

• passport
• Driver's license
• Disability certificate
• Basic Resident Register Card
• My Number Card with Photo

To be used as proof of identity, the document must clearly show your face, name, date of birth, and expiration date .

For example, health insurance cards cannot be submitted as proof of identity because they do not have a photograph. Similarly, with My Number cards, only the front side with the photograph is usually required

Resident registration documents

To open an overseas forex account, need both identity verification documents and proof of residence .

The specific documents required for proving residency are as follows:

• Resident record
• Tax notice
• Documents from financial institutions and other public organizations
• health insurance card
• Basic Resident Register Card
• Utility bill statement
• My Number Card with Photo

To be used as proof of residence, it must be possible to verify your name, current address, and the date of issue.

The deadlines for submitting documents vary depending on the overseas forex broker

Note that the validity period of documents you need to submit may vary depending on the overseas forex broker

For example, XM requires that the resident registration certificate be issued within the last six months, while AXIORY's requirement is three months

As you can see, the deadlines for submitting documents may vary depending on the company, so be sure to check the required documents on their official website in advance.

The required documents can vary depending on the FX broker. Unlike domestic FX brokers, overseas FX brokers are not legally mandated to accept specific documents, so the documents requested may differ from broker to broker. Therefore, the documents considered valid may also vary. When opening an overseas FX account, be sure to check the required documents on the official website beforehand.

Why are identity verification documents required when opening an account?

When opening an account with an overseas forex broker, submitting proof of identity is mandatory. Some people may wonder why proof of identity is required

The reason identity verification documents are required to verify that the account holder is at least 18 years old to confirm that the application was made by the person themselves

When opening an overseas forex account, there are cases where people use borrowed names to apply in order to receive the account opening bonus. The application is then reviewed using identity verification documents to determine if it is legitimate

Furthermore, profits from overseas forex trading can be misused to fund the activities of anti-social forces (a source of funding for terrorist acts). Under the AML ( Anti-Money Laundering ) Act, it is stipulated that an account cannot be opened unless the information on the withdrawal account and the identity verification documents match.

For the reasons stated above, submitting identity verification documents is mandatory when opening an account

When using your My Number, you will need to provide additional identification documents

With domestic FX brokers, you can open an account simply by submitting your My Number Card. However, with overseas FX brokers, if you submit your My Number Card as either proof of identity or proof of address, you will need to provide another document for one of those purposes

The following are cases in which you will need to file a tax return for overseas forex trading

If I don't submit my My Number (social security number), will I get away with tax evasion?

It has been revealed that there is no requirement to submit your My Number (social security number) when trading forex overseas. This might lead some to hope that they can get away with tax evasion

At first glance, it might seem like you can evade taxes by using an overseas forex broker. However, this is a mistake

Tax evasion through overseas forex trading is just as likely to be discovered as tax evasion through domestic forex trading, so it is absolutely not recommended . This article explains why tax evasion through overseas forex trading is so likely to be detected.

Tax evasion through overseas forex trading will be discovered

There are three main reasons why tax evasion in overseas forex trading gets discoveredthere is

1. Deposit and withdrawal data from financial institutions
2. Report on overseas remittances, etc
3. Tax avoidance scheme (CRS)

Now, let's take a closer look at each point

Deposit and withdrawal data from financial institutions

One of the reasons why tax evasion in overseas forex trading is discovered "financial institution deposit and withdrawal data ." Deposits into and withdrawals from overseas forex accounts always involve using financial institutions.

All deposit and withdrawal history, including bank accounts and payment services, is recorded

If an investigation is launched for any reason, it will quickly become clear that you have undeclared income from overseas forex trading

Report on overseas remittances, etc

Another way tax evasion can be discovered is through a document called the "Overseas Remittance Report," which is a record of deposits and withdrawals . This document is created by financial institutions when they receive a remittance of 1 million yen or more from overseas.

Financial institutions are required to submit a "Report on Overseas Remittances, etc." to the National Tax Agency, so if you withdraw more than 1 million yen from overseas forex trading, it will be discovered

If it is discovered that you have an income of 1 million yen or more but have not filed a tax return, your tax evasion will be investigated retrospectively. Tax evasion investigations can go back 5 to 7 years, so there is a risk that tax evasion from several years ago will almost certainly be discovered

Tax avoidance treaties (CSRs)

And the third reason why tax evasion is discovered "tax avoidance schemes .

A "tax avoidance scheme" is one of the treaties concluded among OECD member countries, and it refers to measures taken to avoid double taxation and tax evasion

allows financial and tax authorities in each country to automatically exchange deposit and withdrawal data and customer information with each other

As of August 2025, Japan has concluded tax treaties with 81 countries (regions)

Just because a company is overseas doesn't mean it can't be investigated; tax evasion is strictly prohibited even with overseas forex trading .
