What changed?
As part of the 令和８年度税制改正 (FY2026 tax reform), the Japanese government revised the 非課税限度額 (non-taxable limits) for commuting allowances (通勤手当) paid to employees using private transport (e.g. cars, bikes). These changes took effect from April 1, 2026. (nta.go.jp)
Key highlights:
- People commuting ≥65 km one way using vehicles now have a higher non-taxable ceiling. (nta.go.jp)
- If you regularly pay for parking and meet certain criteria, you can now add up to ¥5,000/month to your non-taxable amount. (nta.go.jp)
- Different non-taxable monthly caps are set by distance zones. E.g., commuting 95 km+ one way grants around ¥66,400/month non-taxable allowance if using traffic tools (cars/bikes). (nta.go.jp)
Why it matters for expats and employees
- Many expats or foreign employees receive commuting allowances as part of salary packages. Under the old rules, long-distance commuting via vehicles often resulted in higher taxable amounts, neutralizing value.
- Now, larger commuting distances yield more non-taxable benefit, and covering parking costs (if criteria met) further boosts the non-taxable portion.
Actionable planning tips
- Employer-employee check: Confirm whether your employer uses the new rate tables and whether your parking qualifies under “certain requirements” to get the ¥5,000 boost. If not, ask for a review.
- Distance matters: If your commute crosses zones (say, moving from 60 km to 70 km), even small changes in residence can increase non-taxable allowance significantly.
- Document parking costs: To get the parking top-up, keep invoices and prove regular usage & proximity to workplace or transit station. Without this, no addition applies. (nta.go.jp)
- Employer payroll setup: Ensure pay slips and payroll classification reflect the new non-taxable amounts correctly, so tax is withheld appropriately.
Practical example
An employee commuting 80 km one way using car, pays ¥4,000/month parking, meets criteria.
Under new rules: Non-taxable commuting allowance = ¥45,700 (base for 65-75 km zone) + ¥4,000 (parking) = ¥49,700/month.
Under previous rules: capped at ¥38,700—so new rules give an extra ≈ ¥11,000/month tax-free.
Considerations and cautions
- Only commuting allowances paid from April 1, 2026 onward use the new limits. Retroactive catch-up not allowed, except via payroll adjustments where possible. (nta.go.jp)
- If commuting distance <2 km one way using a vehicle, allowances remain fully taxable—no non-taxable portion. (nta.go.jp)
- For vehicle commuters, distance calculation rules and route used must follow employer/municipal standards. Keep accurate records.
Beyond commuting: other FY2026 reforms worth tracking
- The FY2026 reform also raised basic deduction (基礎控除) and increased the minimum guaranteed 給与所得控除, especially aimed at lower/mid-income earners. (mof.go.jp)
- International Tourist Tax on departures rose from ¥1,000 to ¥3,000 per exit, as of July 1, 2026. While not directly expat income tax related, it matters for frequent travel. (mof.go.jp)
This rule change shows Japan’s tax policy adjusting to inflation and transport realities. If you or your employer act proactively, you can secure a non-taxable benefit boost.
