Taxes after leaving a job
No year-end adjustment, refund filings, resident tax, unemployment benefits, and insurance transitions.
Leaving before year-end means no employer reconciles your tax, so file a refund return; meanwhile resident tax continues on last year’s income, statutory unemployment benefits are generally tax-free, and you must switch health insurance and pension.

Key points
- No year-end adjustment → file a refund return.
- Resident tax continues based on last year’s income, regardless of unemployment.
- Statutory unemployment (job-seeker) benefits are generally not taxable.
- Switch to national health insurance and national pension (both deductible).
Filing for a refund
Employers withhold assuming a full year of salary, so leaving mid-year usually means too much was withheld. File a refund return using your withholding certificate; you can add the medical deduction, donations, and social-insurance premiums you paid after leaving. You have five years to claim, but filing early gets your money back sooner.
Resident tax and insurance
Resident tax is based on the prior year, so it keeps arriving even while you are unemployed — budget for it. Statutory job-seeker benefits are generally tax-free and do not count like salary for spouse tests, but private income-replacement payments can differ. After leaving, enroll in national health insurance and national pension (or a dependent/voluntary-continuation option), and keep the premium receipts because they are deductible.
Who this is for
- People who left or lost a job
- Anyone between jobs at year-end
What this is not
- Retirement-allowance taxation (see the severance guide)
- Resident tax does not pause for unemployment; the second-year bill can surprise you.
Frequently asked questions
Why did I get a big resident tax bill in my second year?
Resident tax (住民税, about 10%) is charged the year after the income is earned, based on the previous year’s income. So in your first year you often pay little, and in your second year you get a bill for your full first-year income. The same lag means people who stop working or leave Japan can still owe resident tax afterward. Budget for it in advance.
