Overview
The Tax Calculator collection lets you quickly compute key Korean taxes including Value-Added Tax (VAT), comprehensive income tax, capital gains tax, acquisition tax, gift tax, and inheritance tax. Korean tax law is revised annually, and the interplay of tax brackets, deductions, and special provisions makes manual calculation challenging. CalKit's tax calculators are built around current statutory rates so you can prepare VAT filings if you run a business, estimate your year-end tax settlement refund as a salaried worker, simulate capital gains tax before selling real estate, or project gift and inheritance tax when transferring assets within a family. Use these tools to demystify complex tax obligations and develop sound tax-saving strategies.
Tips
- ✔VAT is calculated by subtracting input tax from output tax. Simplified and general taxpayer regimes use different rate structures, so confirm your business registration type first.
- ✔Comprehensive income tax applies progressive rates from 6% to 45%. Maximizing income deductions and tax credits can significantly lower your effective tax rate.
- ✔Capital gains tax rates and deductions vary based on holding period, residency period, and the number of properties you own, so always run a simulation before selling.
- ✔Single-home owners who meet certain requirements (e.g., holding for 2+ years) may qualify for full capital gains tax exemption. Check the eligibility conditions carefully.
- ✔Gift tax deduction limits reset every 10 years, so a long-term gifting plan can spread the tax burden across multiple periods.
- ✔For salaried workers, the key to a good year-end tax settlement is claiming every eligible deduction: credit card spending, medical expenses, education costs, and charitable donations.
- ✔If you have business income, the difference between standard expense rates and actual expense documentation can drastically change your tax bill, so verify which method applies to you.
- ✔Inheritance tax offers various deductions such as spousal deduction and lump-sum deduction. Pre-death gifts are added back into the estate, so comprehensive planning is essential.
FAQ
Q. When is VAT filing due in Korea?
General taxpayers file confirmed returns in January (for July-December) and July (for January-June), with preliminary returns in April and October. Simplified taxpayers file once a year in January. The filing window runs from the 1st to the 25th of the respective month, and late filing incurs penalties.
Q. Who needs to file comprehensive income tax?
You must file if you have business income, freelance income, rental income, or interest/dividend income exceeding KRW 20 million per year, or if you received wages from two or more employers without consolidated reporting. The filing period is May 1-31 each year, extended to June 30 for taxpayers subject to a faithful reporting review.
Q. What are the requirements for capital gains tax exemption on housing?
A one-household, one-home owner who has held the property for at least 2 years (including 2 years of actual residence in designated speculation zones) is exempt from capital gains tax on sale proceeds up to KRW 1.2 billion. Exceptions exist for temporary two-home situations and inherited properties, so individual circumstances must be reviewed.
Q. What is the gift tax exemption limit in Korea?
Exemption limits depend on the relationship between donor and recipient. Gifts from a spouse are exempt up to KRW 600 million; from lineal ascendants to adult children up to KRW 50 million; and to minor children up to KRW 20 million, all over a 10-year rolling period. Amounts exceeding the limit are taxed at progressive rates from 10% to 50%.
Q. What is the difference between year-end tax settlement and comprehensive income tax filing?
Year-end settlement is a simplified process handled through your employer each February for employees with only wage income. Comprehensive income tax filing is a self-reporting process each May for anyone with non-wage income such as business or freelance earnings. Even wage earners can file a correction claim in May if they missed any deductions during year-end settlement.
Q. Are inheritance tax and gift tax rates the same?
Yes, both use the same progressive rate structure: 10% on the first KRW 100 million, 20% up to KRW 500 million, 30% up to KRW 1 billion, 40% up to KRW 3 billion, and 50% above KRW 3 billion. However, the available deductions and calculation methods differ, so the actual tax payable can vary significantly between the two.
Q. Can I use the calculator results directly for my actual tax filing?
CalKit's tax calculators are reference tools for estimating your tax liability. Actual tax filing requires consideration of your specific circumstances, the latest legislative amendments, and various special provisions and exemptions. For official filings, we recommend using the National Tax Service's Hometax platform or consulting a licensed tax professional.
