Commuting Allowance in Japan: Tax-Free Limits

Last updated: 19 October 2026 · the National Tax Agency’s and the Japan Pension Service’s pages · limits as of 1 April 2026

A commuting allowance (通勤手当, tsūkin teate) in Japan is free of income tax up to a limit: by train or bus, the actual fare up to ¥150,000 a month; by car or bicycle, a fixed amount set by the distance. Social insurance is another matter. Health insurance and pension are charged on the whole allowance, so on a salary of ¥300,000 a month, a ¥15,000 train pass adds ¥150,344 a year to take-home, not ¥180,000. To try your own pay and allowance, use the take-home calculator, which has a field for it.

This is a general explanation for an employee in Japan. Your employer decides how much it pays; the limits below decide only how much of that is taxed.

By train or bus

If you commute by public transport, the allowance or pass is tax free up to the cost of the most economical and reasonable route, with a ceiling of ¥150,000 a month. Anything above that ceiling is added to your salary for income tax. Very few people reach it.

By car or bicycle

If you drive, ride or cycle, the tax-free amount depends on the one-way distance along the route you take:

If you also pay for parking that meets the National Tax Agency’s conditions, up to ¥5,000 a month of the parking charge is added to the tax-free amount, and tolls on a reasonable route can be added as well, up to the same ¥150,000 a month in all.

Mixed routes and the fine print

• Train and car together. If you drive to a station and take the train, the tax-free amount is the monthly pass plus the car amount for the distance you drive, still up to ¥150,000 a month in all.
• Shinkansen and express trains. Their fares can count if that route really is the most economical and reasonable one; a Green Car supplement never does.
• Part-time and short contracts. The limits are worked out by the month for everybody, including part-timers and staff hired for a short time.

Social insurance counts all of it

The Japan Pension Service lists the commuting allowance as part of the pay your health insurance and pension grades are set from. So the allowance raises your premiums even though it is not taxed, and a large one can lift you into a higher grade. That also makes your future employees’ pension slightly larger.

Two examples

For somebody in Tokyo, under 40 and single, on ¥300,000 a month:

In both, the allowance moves the health insurance and pension grade from ¥300,000 to ¥320,000, which is most of the difference. For the car, ¥13,500 a month is tax free and the other ¥6,500 is taxed like salary. Neither allowance is spending money: it pays for the commute.

Questions people ask

Is the commuting allowance taxed in Japan?

Not up to the limit for how you travel, and only the part above it is taxed. Social insurance is different: health insurance and pension are charged on the whole allowance.

Does a bigger commuting allowance raise my pension?

It can. The allowance counts towards the pay your pension grade is set from, so a larger one can move you into a higher grade: higher premiums now, and a slightly higher pension later.

Does the commuting allowance count towards a spouse’s ¥1,300,000 limit?

Yes. For being a dependent on a family member’s health insurance, the income includes allowances, so a spouse’s commuting allowance is counted. It does not count towards the income tax limits, because the tax-free part is not income for tax.
