Not HomeTax. Compare simplified VAT (exemption / 0.5% credit) with general VAT (10% minus input tax) from two numbers.

Annual supply (VAT-inclusive sales)Purchase invoice supply (ex-VAT)

使い方

How it works

Not a HomeTax form. Enter annual VAT-inclusive supply, purchase-invoice supply, and industry. We apply 2026 rules:

Simplified eligibility under ₩104,000,000.
Payment exemption under ₩48,000,000 (you still file).
Simplified tax = supply × add-value rate × 10% − purchase × 0.5% (no refund if credit exceeds tax).
General tax = supply ÷ 1.1 × 10% − input VAT. Negative ≈ a refund direction.

Copy the comparison before you talk to an accountant. Card credits and mixed businesses are not modeled.

FAQ

Income tax?

VAT types only. Income tax and social insurance are out of scope.
