Understanding Japanese End-of-Year Tax Filing

A Guide to White and Blue Returns for Freelancers and Small Business Owners

If you live or work in Japan as a freelancer, sole proprietor, or small business owner, you are responsible for filing your own income tax each year. Japan’s National Tax Agency (NTA) provides two main filing options: the White Return (Shiroiro Shinkoku) and the Blue Return (Aoiro Shinkoku). Both systems allow you to report income and expenses, but the Blue Return offers greater benefits for those who are willing to maintain proper records.

This guide explains the difference between the two, who can use them, what documentation is needed, and how to prepare for the end-of-year submission.

1. Overview of the Japanese Tax Year

Japan’s tax year runs from January 1 to December 31.
All self-employed individuals and freelancers must submit their income tax return between February 16 and March 15 of the following year.

Filing late can result in penalties or fines, so it’s important to prepare all records before the new year begins.

2. White Return (白色申告)

What Is the White Return?

The White Return is the simplest form of tax filing in Japan. It is designed for freelancers, small business owners, or individuals with irregular income who do not wish to maintain double-entry bookkeeping records.

Who Can File a White Return?

You can file a White Return if:

• You are self-employed or freelance but have not applied for Blue Return status.
• You have small-scale or occasional income.
• You prefer simpler bookkeeping and are willing to forgo some tax deductions.

Required Records and Documentation

White filers must keep a simple ledger of income and expenses for at least seven years. You will need:

• A record of all business income (invoices, bank statements, receipts).
• A list of business expenses such as rent, utilities, travel, and supplies.
• Proof of withholding tax (if any).
• Any relevant receipts or invoices.

There is no requirement for double-entry accounting or a balance sheet, but totals must still be accurate and traceable.

Advantages and Disadvantages

Advantages:

• Easier to maintain.
• Suitable for those with small or part-time income.
• No prior registration needed.

Disadvantages:

• Fewer tax deductions.
• No special allowances for losses or depreciation.
• Not as beneficial for long-term business growth.

3. Blue Return (青色申告)

What Is the Blue Return?

The Blue Return system is designed for individuals and small businesses who maintain proper accounting records. It allows for additional deductions, such as the ¥650,000 Blue Return deduction, which reduces taxable income.

Who Can File a Blue Return?

You can file a Blue Return if:

• You are a sole proprietor or small business owner with regular income.
• You have submitted a “Notification of Intention to File a Blue Return” (青色申告承認申請書) to your local tax office before March 15 of the first year you wish to use it.
• You are willing to maintain double-entry bookkeeping and keep detailed records.

Required Records and Documentation

Blue filers must keep more detailed accounting books and records, including:

• A general ledger and journal showing income, expenses, and assets.
• Balance sheet and profit-and-loss statement at year-end.
• Invoices, receipts, and bank records for all transactions.
• Depreciation schedules for assets such as computers, vehicles, and equipment.
• Home office deductions and partial utilities or rent records (if applicable).

Blue Return records must also be stored for at least seven years and should be available for inspection if the tax office requests them.

Advantages and Disadvantages

Advantages:

• Up to ¥650,000 deduction for accurate double-entry bookkeeping.
• Can carry forward losses for up to three years.
• Greater credibility with banks and lenders.
• Eligible for family employee salary deductions if you pay a spouse or relative.

Disadvantages:

• Requires accurate and consistent bookkeeping.
• Must apply in advance and meet accounting standards.
• More complex year-end preparation.

4. Gathering the Necessary Documents

To file either type of return, you will need to prepare the following:

Income Documentation

• Invoices or receipts from clients.
• Bank statements showing deposits and withdrawals.
• Payment slips (源泉徴収票) if tax has been withheld.

Expense Documentation

• Receipts for all business expenses.
• Utility and rent bills, with business use percentages clearly noted.
• Transportation and communication costs (train cards, mobile bills, internet).
• Office supply and equipment receipts.
• Insurance and pension payments if deducted as business expenses.

Personal and Tax Forms

• My Number card or notification card.
• Personal identification (passport or residence card).
• Bank account information for refunds.
• Previous year’s tax return if applicable.

5. How to File Your Return

You can file in several ways:

1. e-Tax Online System – the NTA’s digital filing platform.
2. Tax Office (税務署) – submit paper forms directly at your local office.
3. Mail – send completed forms to the tax office before the deadline.

Most freelancers now use e-Tax, which allows you to upload documents, attach digital receipts, and submit electronically. It is faster and provides an immediate confirmation receipt.

6. End-of-Year Preparation Tips

To make filing easier, prepare gradually throughout the year.

• Keep monthly income and expense records.
• Use accounting software or an Excel spreadsheet to track totals.
• Reconcile your bank balance monthly.
• Store all receipts and invoices digitally in organized folders.
• Consult a tax accountant (税理士) if your income is high or your situation complex.

7. Which Return Should You Choose?

If you expect your freelance work to grow or plan to claim significant expenses, it’s usually best to register for the Blue Return early.

8. Final Thoughts

Filing taxes in Japan can seem complex, but once you understand the two systems, it becomes manageable. The White Return is simple and quick for small earners, while the Blue Return rewards discipline and good record-keeping with generous tax benefits.

Whichever you choose, start your bookkeeping early, store your receipts, and review your records monthly. By the time tax season arrives, your end-of-year filing will be smooth and stress-free.
