Specific Expense Deduction Calculator
Enter your commuting, relocation, training, qualification, and other job-related expenses to calculate the Japanese Specific Expense Deduction under Income Tax Act Article 57-2, plus estimated income and resident tax savings.
Tips
- Few taxpayers use this deduction, but it tends to apply more often to professionals with high training or qualification costs, such as employees studying for accounting or legal certifications.
- Since the employment income deduction grows with salary, the threshold (half of that deduction) also changes with your income. Try different salary figures to see how much specific expense would be needed to qualify.
- You will need a "certificate of specific expenses" issued by your employer's HR or general affairs department. Requesting it as soon as an expense occurs avoids a last-minute rush at tax filing time.
- Relocation and return-home travel expenses are especially relevant to employees with job transfers or those living apart from their families for work. Years with many personnel transfers are worth checking.
Frequently asked questions
Side Note — Why Japan started recognizing "employee expenses"
The Specific Expense Deduction was introduced in Japan's 1987 tax reform. Salaried employees' income tax had always used the "employment income deduction," a flat-rate estimate of necessary expenses automatically subtracted from salary, with no mechanism to itemize and deduct actual costs. The system is said to have emerged from debate over fairness: self-employed individuals could deduct their actual business expenses, while employees had no equivalent option.
When first introduced, the scope of eligible expenses was narrow and the bar for qualifying was high, so very few people used it. A 2013 tax reform significantly expanded the scope — broadening qualification expenses to cover any credential needed to provide professional services, and adding the new "job-required expenses" category (books, clothing, entertainment) with its ¥650,000 cap.
Even so, the number of people who actually claim it remains a small fraction of all salaried employees. This is largely because the employment income deduction itself already provides a substantial automatic allowance scaled to income, leaving relatively few employees whose out-of-pocket specific expenses exceed that threshold.
