자영업자 세금 계산기

The app's interface is in Korean only. A reference calculator for sole proprietors and freelancers in Korea. Enter your annual revenue and an expense amount you assume, and the app shows a national income tax estimate based on the law as checked on October 19, 2026, plus a simple 1/12 split of that estimate. When you change the expense, it shows how the estimate changed from the previous result. Every figure is a reference estimate, not an amount to file or pay. The app does not file returns or replace tax advice, and it is not a government app. Income tax reference - Tax year 2026 by default; 2025 can be selected - Uses the expense you enter; no industry code is required - 2025 simple expense rates only for two verified industry codes (552101, 525101) - Assumes only the basic personal deduction for one person - Local income tax figures are hidden until the source table is re-verified - Items not included (other income, credits, prepaid or withheld tax, penalties, refunds) are listed with each result VAT reference - General taxpayer: supply value x 10% - Simplified taxpayer: total x industry value-added rate (15-40%) x 10% - Same-total comparison between the two, without deductions or eligibility judgment Pension, health and long-term care (income-based examples) - Monthly examples only for the verified period July-December 2026 - Employment and industrial accident insurance are not included Filing schedule - 2026 VAT and income tax dates; dates not verified against the source are marked as needing confirmation Privacy - No account, sign-in or permissions - Inputs stay in memory and are not saved after the app closes - No server, analytics, ads or tracking; content leaves the device only when you share it after a preview
