It covers VAT for general and simplified taxpayers, 3.3% withholding, severance pay, cafe menu cost ratios, jeonse-to-monthly-rent conversion, brokerage fees, loan interest, overseas stock capital gains, part-time net pay, year-end tax settlement, seller break-even ROAS, rent-to-sales ratio, card sales reconciliation, income tax, the four major insurances, dependent status on national health insurance, VAT on closing a business, key money, retirement pension (IRP) and gift tax. Each page shows the calculation formula and the legal basis beside the result, with 2026 rates, so a reader can check a figure instead of trusting it.

Each result sits next to its formula, the 2026 tax rates and the legal basis in Korean, with no signup and no ads; the figures are calculated in the browser and nothing is uploaded.
