Blue Form Tax Return in Japan: Benefits and Key Requirements
Hi, my name is Taisei Koshida, and I am a certified public accountant and licensed tax accountant in Japan.
I support foreign business owners and foreign entrepreneurs with accounting and tax matters in Japan, especially when language is a barrier.
If you are unfamiliar with the Japanese tax system or the Blue Form (Aoiro Shinkoku), this article explains its main tax benefits, accounting requirements, and application deadlines.
For many individuals and companies starting a business in Japan, applying for the Blue Form is an important part of tax planning.

What Is the Blue Form (Aoiro Shinkoku) in Japan?
Both individual business owners and corporations in Japan can apply to file tax returns under the Blue Form (Aoiro Shinkoku) system.
The Blue Form offers several tax advantages in exchange for maintaining proper accounting records and meeting certain requirements.
For individual business owners, proper bookkeeping is particularly important if you want to claim the larger Blue Form special deduction.
Meeting the application and tax filing deadlines is also essential to receive the available tax benefits.
For foreign entrepreneurs starting a business in Japan, understanding the Blue Form system early can help avoid missing important tax deadlines.
Key Benefits of the Blue Form Tax Return
Carryforward of Losses
You can offset past losses against future profits:
- Individuals: up to 3 years
- Corporations: up to 10 years
This is especially useful for startups, which often incur losses in the early stages.
Reduced Risk of Estimated Taxation
Another advantage of the Blue Form is that your taxable income is supported by proper accounting books and records.
If proper records are not maintained, the tax office may determine taxable income based on available information in certain circumstances.
Maintaining proper accounting records under the Blue Form system can therefore provide stronger support for the income and expenses reported in your Japanese tax return.
Immediate Expensing of Small Assets
Eligible small and medium-sized businesses using the Blue Form may be able to immediately expense certain depreciable assets costing less than JPY 300,000 per asset, subject to applicable requirements and annual limits.
Normally, depreciable assets above certain thresholds must be depreciated over their useful lives.
This special rule can therefore provide a useful tax benefit for small businesses in Japan when purchasing equipment and other business assets.
Special Deduction of Up to JPY 650,000 (Individuals)
Eligible individual Blue Form filers may claim a special deduction of up to JPY 650,000.
To qualify for the JPY 650,000 deduction, certain requirements must be met, including:
– Keeping books using double-entry bookkeeping
– Preparing and submitting the required financial statements
– Filing the tax return by the statutory deadline
– Filing electronically through e-Tax or meeting the requirements for qualified electronic bookkeeping
If the additional requirements for the JPY 650,000 deduction are not met, a JPY 550,000 or JPY 100,000 deduction may apply depending on the circumstances.
Salary Payments to Family Members (Individuals)
Under the Blue Form system, salaries paid to qualifying family members who work in the business may be treated as deductible business expenses if certain requirements are met.
A separate notification generally needs to be filed in advance to use this treatment.
Important Deadlines
For Individual Business Owners
You must submit the Blue Form application by March 15 of the same tax year.
If you start a new business, the application must be submitted within two months of starting the business.
For Corporations
A corporation that wants to use the Blue Form generally needs to submit the application by the day before the beginning of the fiscal year for which it wants to use the Blue Form.
For a newly established corporation, the deadline for the first fiscal year is generally the day before the earlier of:
– Three months after the date of incorporation; or
– The end of the first fiscal year.
This deadline can be particularly important for companies with a short first fiscal year.
