About this site

Purpose

We provide free calculators so that part-time workers, people with side jobs, and employees can check their take-home pay and taxes with their own numbers. Most pages are in Japanese; the Furusato Nozei limit calculator is also available in English. When the rules change, we review the figures used in the calculations. Each page shows the date the rules were checked, the sources, and the formulas.

Advertising

This site uses an affiliate program (Moshimo Affiliate). If you sign up through a link in a box labeled “advertisement” (広告) on a page, the site operator may receive a fee. Calculation results and explanations are not changed because of advertisements or fees.

Privacy

• What you enter in a calculator is calculated only in your browser. It is not sent or stored anywhere.
• To count visits, we may use analytics that do not use cookies (Cloudflare Web Analytics). We do not collect information that identifies you.
• On sites linked from advertisements, your information is handled under that site’s own policy.

Disclaimer

Calculation results are estimates. Actual amounts depend on detailed conditions of the rules, your health insurance, and the city where you live. Before making an important decision, please check with your employer, your health insurance provider, your city office, or the tax office. The site operator cannot accept responsibility for any loss arising from the use of the information on this site.
