2022 NTA Circular Revision

The 2022 revision of NTA Basic Circular 35-2 (所得税基本通達35-2) clarified the criteria for distinguishing business income (事業所得) from miscellaneous income (雑所得). Proper bookkeeping is the most important factor.[4]

Proper books maintained → presumed business income (事業所得)

Whether double-entry or simple bookkeeping, maintaining proper records generally qualifies income as business income.

No books + revenue ≤ ¥3M → miscellaneous income (雑所得)

Without proper books, income ≤ ¥3M is generally classified as miscellaneous income (unless proven otherwise).

This circular revision underscores the importance of proper bookkeeping — not just for blue filing benefits, but for having your income classified as business income (事業所得) at all. Cloud accounting software makes this easy.[4]

When White Filing Is Fine

In these situations, there's no pressing need to switch to blue filing (青色申告).

Salaried worker with small side income

If side income (miscellaneous income / 雑所得) is ≤¥200,000/year, you don't even need to file (except for resident tax). Even above ¥200K, white filing with simple books works fine for small scale.

First-year freelancer

You might miss the blue filing application deadline in your first year (must apply within 2 months of starting). It's common to file white the first year and switch to blue from the next year.

Very simple business with few transactions

If you have very few transactions per year and minimal expenses, the overhead of double-entry bookkeeping may not be worth it. Simple bookkeeping is sufficient.

How to Switch to Blue Filing

Three steps to switch from white filing (白色申告) to blue filing (青色申告).[3]

1

Submit the Blue Filing Approval Application (青色申告承認申請書)

Submit to your local tax office by March 15 of the tax year (or within 2 months of starting a new business). Can also be submitted via e-Tax.

2

Start double-entry bookkeeping (複式簿記)

Double-entry bookkeeping is required for the ¥650K deduction. Cloud accounting software (freee, Money Forward, Yayoi) makes this easy with auto-categorization.

3

File via e-Tax for the full ¥650,000 deduction

For the maximum ¥650K deduction, you must e-file via e-Tax (paper filing reduces it to ¥550K). Just need a My Number Card and smartphone.

The blue filing approval application (青色申告承認申請書) deadline is March 15 of the tax year. For new businesses, you have 2 months from the start date to apply for the same year.[3]
To receive the full ¥650,000 blue deduction (青色申告特別控除), you must use double-entry bookkeeping (複式簿記) AND either file via e-Tax or use qualified electronic record-keeping. Simple bookkeeping (簡易簿記) only qualifies for the ¥100,000 deduction.[2]
