How to say "tax-free" in Japanese

• 無税むぜいCommon
  no-adjectiveThe common word for the duty-free sense: goods or trade carried free of customs duty or tariff. Its 'tax-free' reading is this duty-free one, not exemption from a tax itself.
  私は無税むぜいでカメラを買かった。↗

  I bought a camera free of tax.
• フリータックス
  no-adjectiveA katakana loanword meaning simply 'free of tax'. As a less common borrowing, it is seldom the word you want; one of the other words here will usually express the sense better.
• 非課税ひかぜい
  no-adjectiveThe choice for the tax-exempt sense: something falls outside a tax altogether, not subject to it in the first place. When 'tax-free' means 'exempt from tax', this is the word you want.
• 無役むやく
  no-adjectiveLiterally 'without duties'; an uncommon word whose 'tax-free' sense is marginal — it is really about freedom from duties or levies. You will seldom, if ever, want it to say 'tax-free'.

Choose 非課税 for the tax-exempt sense, 無税 for goods free of customs duty; 「フリータックス」 is a less common loanword for 'free of tax', and 無役, an uncommon word about freedom from duties, is seldom what you want.
