Freelance Work in Japan: Status and Tax Obligations

Published on May 4, 2026 and written by Cyril Jarnias

Freelance work in Japan, a rapidly growing sector, is proving to be a fascinating blend of tradition and innovation. While the country is known for its strong work ethic and solid corporations, the rise of freelancers and self-employed workers is beginning to challenge the status quo. However, navigating the legal and administrative framework can be complex. Indeed, Japanese freelancers must contend with specific obligations regarding tax filings and social security that differ significantly from Western norms. This article invites you to delve into the little-known world of freelancing in Japan, exploring the unique challenges and rich opportunities it presents.

Understanding the Status of Self-Employed Workers in Japan

Definition of a Freelancer in Japan

In Japan, a freelancer refers to a way of working without being employed by a specific organization such as a company or association, using one’s own experiences, knowledge, and skills to earn income through subcontracting contracts, etc. Although it is not a term clearly defined by law, the standards set by bodies such as the Ministry of Health, Labour and Welfare, the Cabinet Office, and the Small and Medium Enterprise Agency include the following characteristics.

• Independent activity without belonging to an organization or group
• No employees (salaried workers)
• No physical storefront
• Business management as an individual or a one-person company
• Workers in agriculture, forestry, and fisheries are not included

For this reason, sole proprietors or single-representative CEOs may be considered freelancers depending on the conditions. Furthermore, sole proprietor is a tax and administrative classification, while freelancer is understood as a form of social work.

Characteristics and Legal/Regulatory Standards

Recently, in Japan, the Act on the Rationalization of Transactions Involving Specific Subcontracting Businesses (commonly known as the New Freelance Act) was enacted and is set to take effect in November 2024. This law clarifies for the first time the image of a specific service provider = freelancer to a certain extent as a subject of legal protection. The main points are as follows.

• Individual (or single-representative company) with no employees
• Primarily BtoB subcontracting contracts (manufacturing goods, creating information products, providing services)

To be recognized in this position,

• No employment relationship with an organization
• Conclusion of a contract for each assignment and self-management of risks, are considered important points.

The Labor Code and other work-related laws (minimum wage, paid leave, etc.) generally do not apply, and all responsibility falls on the individual. On the other hand, after the new law comes into effect, certain protective measures such as the obligation for written clarity, setting payment deadlines, and preventing harassment become mandatory for ordering companies.

Tax and Administrative Obligations

When engaging in income-generating activities continuously in Japan, it is recommended in many cases to submit a business start declaration as a sole proprietor and apply for approval of the blue tax return (optional). This includes the following procedures.

• Submit a business start/closure declaration to the competent tax office
• Prepare and submit a tax return every year in February-March
• Payment of income tax/consumption tax may be required

Regarding consumption tax, if the taxable sales two years prior exceed 10 million yen, you become liable for the tax two years later; below this amount, you are exempt, but since the introduction of the invoice system in October 2023, registration to issue qualified invoices is often required for client management purposes. Additionally, subscribing to National Health Insurance/National Pension and paying residence tax remain the individual’s responsibility.

Unique Japanese Work Culture and Market Environment: Pros and Cons

Advantages

• Great freedom in choosing work time and location (high compatibility with telework)
• Ability to manage multiple projects = possibility to diversify income sources
• Potential to increase compensation level based on skills, potentially leading to building one’s own brand

Disadvantages

• Social security systems (unemployment benefits/sickness benefits, etc.) are limited or the trend is towards an increase in the cost borne by the individual (need to maintain health insurance/pension enrollment, but not automated as for salaried employees)
• Due to the strong orientation towards social stability, a negative image persists such as instability, lack of responsibility, etc.
• Under the Japanese culture of lifetime employment, explaining career progression becomes more complex
• As a unique Japanese custom, during business activities, building a network is difficult, and it is not uncommon to face challenges in establishing credibility (including financial evaluation)

Social and Professional Evaluation

Although there is a trend towards improved evaluation in creative IT-related professions, overall, a predominant belief in the status of a regular salaried employee still persists in Japan. Questioning stability can lead to lifestyle restrictions such as stricter criteria for evaluating housing loans. On the other hand, there is a growing trend in demand for professional profiles in highly specialized fields. Result-oriented project platforms are gradually appearing, but the culture of project-based work is not yet as widespread as in the West.

Examples of Available Resources

You can use the following support services.

• Use of various crowdsourcing services/matching sites (e.g., Lancers, Crowdworks)
• Professional and side-career association for freelancers (information provision, welfare benefits, consultation office)
• Sites publishing educational materials on rights referring to guidelines from the Ministry of Economy, Trade and Industry / Ministry of Health, Labour and Welfare
• Business start-up support offices of chambers of commerce and local governments (funding, introduction of accountants, etc.)
• Many opportunities to participate in community-type information exchange groups on social media, online fairs

	Advantages	Disadvantages
Freedom (time, place, project choice)	✓ High decision-making authority ✓ Possibility to adjust work-life balance	✗ Worry about income if projects decrease ✗ Self-management essential
Social security, credibility, etc.	✓ Possibility to design one’s own benefits depending on conditions (including using associations)	✗ Low coverage from public systems ✗ Many cases of strict evaluation by financial institutions
Specialized evaluation and market environment	✓ Trend of increasing demand for high skills centered on IT and design fields	✗ Penetration ongoing in general professional categories ✗ Persistent feeling of lack of understanding by society

In summary, if you aspire to serious independence in Japan, it is essential to carefully read the latest guidelines, understand taxation, contract practices, and prepare to utilize support networks.

Steps to Obtain Self-Employed Status

Required Documents and Forms to Fill Out

• Notification of Opening/Closing of Individual Business (common name: Opening Notification)
• Identification document (My Number card, driver’s license, passport, etc.)
• Proof of My Number (the My Number card can serve as both)

If you are a foreign national, a residence card or a certificate of work authorization proving permission to work is also necessary. Depending on visa conditions, such as the Business Manager residence status, additional documents may be required.

Administrative Steps and Involved Agencies

Step	Content	Filing Location	General Period
1	Creation of the Opening Notification	Tax Office (under the National Tax Agency)	Within one month of starting business
2	Filing the Notification of Starting Individual Business	Prefectural Tax Office (responsible for local taxes)	Varies by prefecture, but generally within one month
3* (if applicable)	Obtaining a permit (restaurant business, etc.)	Public Health Center / Police Station, etc.	Depends on content (a few days to a few weeks)

*Additional documents are required if you hire employees or wish to file a blue tax return.

Use of Online Platforms

Common Mistakes to Avoid During Registration and Tips

• Forgetting to attach My Number or identification documents

• Error in the start date: interpreted as the actual start date of the activity. Even if vague, enter it consistently.
• Inappropriate use of brand names in the trade name field

Tips: Online services work via questionnaires, which reduces errors and is recommended. If you want a copy returned, don’t forget to include a reply envelope. If you are a foreign national, always check if you have work authorization.

Regarding Fees

The procedure itself is generally free of charge. However,

• Postage costs: approximately 100 yen
• Permit application fees: approximately 10,000 to 30,000 yen (depending on content)
• Specialist fees:
  • Consultation/drafting by administrative scriveners or tax accountants: 10,000 to 50,000 yen (some initial consultations are free)

Item	Estimated Cost
Opening Notification	Free
Online Use	Free
Postage	Approx. 100 yen
Tax Accountants/Administrative Scriveners	10,000 to 50,000 yen

Key Points: While you can manage on your own, it is sometimes good to consult a specialist if you have doubts. Many city halls now offer multilingual support. For any questions, contact the nearest tax office or prefectural tax office directly.

How to Declare Your Income as an Expatriate

Tax Obligations and Registration for Foreigners Working Independently in Japan

Foreigners who work as independents or freelancers in Japan and reside in the country (i.e., have an address or place of stay for more than one year) are considered residents. In this case, they have the obligation to pay income tax as well as residence tax. When starting the business, it is essential to submit the Notification of Opening or Closing of Individual Business to the competent tax office and carry out proper tax registration. Failure to register may result in penalties or adverse consequences, so it is advisable to complete these procedures as early as possible.

Types of Income to Declare and Their Treatment

The main categories of income that self-employed foreigners must declare include:

• Business income or fees received in Japan
• Remuneration from contracts abroad (foreign-source income)
• Real estate income (whether domestic or foreign)
• Investment or dividend income

Residents other than non-permanent residents are taxed on their worldwide income, whether from Japanese or foreign sources. In contrast, non-permanent residents (non-nationals who have been in Japan for five years or less out of the last ten years) are, in principle, taxed only on Japanese-source income and foreign-source income remitted to Japan. In the case of non-residents, only Japanese-source income is taxable. When filing, it is important to check the applicable rules for each relevant category.

Tax Filing Procedure, Deadlines, and Required Documents

The tax filing period runs annually from February 16 to March 15. During this period, it is necessary to prepare and submit the income tax return for the previous year (January 1 to December 31) using the appropriate forms, such as the Income Tax Return Form B, to the competent tax office. To benefit from the special deduction for blue tax returns, prior approval and additional record-keeping are required.

Examples of supporting documents to attach:

• Residence card or other identification document
• Profit and Loss Statement / Blue Tax Return
• In case of international transactions: copy of the contract or transfer statement, etc.
• For using tax deductions for dependents abroad: proof of family relationship, with official translation attached

Even in the case of a refund, it is possible to file after the deadline, although failing to make payment before the due date (generally March 15) incurs late payment interest, which should be taken into consideration.

Double Taxation Avoidance Agreement and Application of Tax Treaties

Often, self-employed foreigners are also subject to tax in their home country for international transactions in the same year. In this case, it is important to check the applicability of tax treaties (double taxation avoidance agreements) concluded between Japan and the country concerned. These treaties provide for provisions such as:

• A mechanism to deduct, as a foreign tax credit, the amount already paid locally to foreign entities or individuals,
• An exemption for certain specific categories of salaries or fees in the home country

To do this, documents like the foreign withholding tax certificate or local payment receipts may be necessary, so it is recommended to prepare these documents in advance.

Practical Tips and Recommendation to Consult Professionals

When filing a tax return for the first time in Japan, pay attention to the following points:

• Mandatory notification to the competent offices immediately after opening
• Meticulous record-keeping for each contract
• Avoiding errors in classifying income types
• Creating a list of documents to attach and obtaining them promptly

For complex situations – such as transactions between multiple countries, multilingual contract documents, determining the application of multiple deductions – it is strongly recommended to seek assistance from professionals (certified public accountants / specialized accounting firms / consultation services set up by each municipality). In uncertain or special situations, it is best to seek advice as soon as possible to avoid any mistakes.
