Calculate tax-inclusive/exclusive prices and tax amount by entering a price and tax rate (10% or 8%). Supports both tax-exclusive → inclusive and inclusive → exclusive conversions.

Result
Price excl. tax ¥ {{ fmt(result.exclude) }}
Tax amount ¥ {{ fmt(result.tax) }}
Price incl. tax ¥ {{ fmt(result.include) }}

Tips

  • The 8% reduced rate applies to: food and beverages (excluding alcohol and restaurant meals), and newspapers sold by subscription (published twice a week or more).
  • When converting inclusive → exclusive price, fractions are rounded down (standard practice under Japan's Consumption Tax Act).
  • Under the Invoice System (introduced October 2023), the rounding rules for consumption tax amounts on qualified invoices have become stricter.
  • "Tax-inclusive" vs "tax-exclusive" price: the terms refer to whether the displayed price already includes consumption tax.

FAQ

The 8% reduced rate applies to food and non-alcoholic beverages (excluding restaurant meals) and newspapers sold by subscription (published at least twice a week). All other goods and services use the standard 10% rate.

Dividing by 1.1 (or 1.08) rarely gives a whole number, so the result is rounded down per Japan's Consumption Tax Act. This means 110 yen (incl. tax) converts to 100 yen (excl. tax), but 111 yen converts to 100 yen as well.

This tool calculates tax on a per-item basis. Under Japan's Invoice System (since October 2023), rounding of the total tax on a single invoice is limited to once per invoice, so please verify the final figure when preparing official documents.

Note — Japan's Consumption Tax History: 35 Years of Change

Japan's consumption tax launched on April 1, 1989, at 3%. Public resistance to an indirect tax was strong from the outset — the Ohira Cabinet's "general consumption tax" proposal (1979) was abandoned due to backlash, and the Nakasone Cabinet's "sales tax" bill (1987) was also scrapped. The tax finally passed after two earlier failures.

The rate rose to 5% in 1997, 8% in 2014, and 10% in 2019. The 2019 hike introduced a reduced rate system that kept food and newspapers at 8% — an unusual two-tier structure. The rule "eat in the restaurant: 10%, take away: 8%" attracted widespread attention, and businesses such as fast-food chains and convenience stores often struggled with edge cases.
