Japan FAQs
Do freelancers pay social insurance in Japan?
Freelancers join National Health Insurance (kokumin kenko hoken) and National Pension (kokumin nenkin) instead of employee shakai hoken. Rates differ from salaried employees.
Do I need to file a tax return?
Yes. Freelancers and sole proprietors must file a kakutei shinkoku (final tax return) by March 15 each year for the previous year's income.
What about consumption tax?
Businesses with revenue over 10 million yen in the base period must register as a taxable enterprise and charge consumption tax.
