noun which may take the genitive case particle 'no', noun
tax included; including tax
Used for prices that already include tax. Often contrasted with 税別 (tax excluded) or 税引き (after-tax). The glosses 'pretax' and 'before tax' refer to income or profits before tax is deducted, which is a separate usage; for prices, it means tax is included.
