Frequently asked questions
What is SEOULTAX Employee Refunds?
SEOULTAX Employee Refunds is a tax refund platform for employees, built and operated by tax professionals who specialize in refunds and tax correction claims. Under Article 45-2 of Korea’s Framework Act on National Taxes, a correction claim allows taxpayers to reclaim overpaid taxes from the past five years. Our AI technology checks more than 100 tax credits and reductions that employees or employers may have missed. A tax professional then reviews the results to handle your refund accurately and efficiently.
How do I check and apply for a refund?
Select [Check my estimated refund], sign up with your Kakao account, and complete KakaoTalk identity verification to see your estimated refund. You need a Hometax account before you can check your refund. Select [Request a refund review] on the results screen. Our team will review applications in order and contact you individually.
How long does it take to receive a refund?
It usually takes one to two months after you apply. Timing may vary depending on when you apply and the tax office handling your claim. The process is: Refund estimate → Tax professional review and correction claim filing → Tax office review → Refund deposit → Service fee payment (after your refund).
What is the service fee?
Checking your estimated refund is 100% free. A tax service fee of 33% of your final refund (VAT included) applies only if you actually receive a refund. You pay only after the tax office deposits your refund. If you sign up using a friend’s invitation link or referral code, you get 10% off the service fee.
What are the benefits of inviting a friend?
You receive — 3% of your friend’s final refund when they sign up with your invitation link or referral code and receive their refund. (A 3.3% withholding tax is deducted from the referral reward.) Your friend receives — 10% off the service fee. Find your invitation link, referral code, and invitation status under My account → Invite friends. There is no limit on how many friends you can invite. Rewards earned each month are paid together on the 5th of the following month.
When do I enter a referral code? Can I change it later?
Use your friend’s invitation link, or enter their referral code (or mobile number) when you complete your details after Kakao login. If you leave it blank, you can add it once under My account → Edit my details. Once a referrer is registered, your 10% service fee discount applies. You cannot change a referral code after registering it. Contact support if you need to make a change.
