Get 5 Years of Income Tax Refunds Free with 'One Click'

NTS Launches 'One-Click' Service
for Comprehensive Income Tax Refunds
Fast, Accurate, and Commission-Free Refunds Now Available

On the 31st, the National Tax Service (NTS) launched the 'One-Click' comprehensive income tax refund service, which is convenient, accurate, and free of commission fees.

The One-Click service displays refund amounts for up to five years at once and allows users to complete the refund application with a single click.

Seongjin Lee, Director of Informatization Management at the National Tax Service, is explaining the comprehensive income tax refund service 'One Click' at the Government Sejong Complex on the 31st.

Since 2022, the NTS has proactively guided refund payments to over 10 million taxpayers, including delivery riders and private academy instructors, refunding approximately 2.6 trillion KRW as part of active tax administration support.

Alongside this, the NTS expanded the 'All-Fill' filing assistance service, which calculates tax amounts, providing it to 7 million people last year?over 50% of comprehensive income tax filers. Building on this service experience and expertise, the NTS systematically prepared and now offers the refund service under the name One-Click.

Calculating refund amounts is a complex task requiring analysis of vast big data, including various tax returns, payment statements, and year-end tax adjustment simplified data, as well as reflecting tax law amendments over the past five years to accurately compute tax amounts.

For example, it involves carefully reviewing whether the combined annual income of family members exceeds income thresholds, checking for duplicate deductions, and applying the most favorable filing method for taxpayers by considering differences between withholding tax rates and comprehensive income tax filing rates. These intricate calculations were resolved through big data analysis. Through the One-Click service, the NTS plans to guide approximately 3.11 million taxpayers on comprehensive income tax refund filings totaling around 290 billion KRW.

Specifically, refund recipients include 3.11 million individuals such as personal service income earners or wage earners with refund amounts of 5,000 KRW or more, considering administrative costs. An NTS official stated, "We hope to save precious time for N-jobbers (750,000 people, 24%) who missed comprehensive income tax refund filings due to busy work lives, reduce the inconvenience for elderly taxpayers (1.07 million people aged 60 and above, 34%) who forgot to file refunds while working after retirement, and contribute to the livelihood economy by disbursing refunds totaling 290 billion KRW."

If the amount guided by the One-Click service is filed without modification, the refund review period will be significantly shortened, with payments planned within one month. Even if the amount is modified during filing, the comprehensive income tax refund verification system will ensure payments are made as quickly as possible within two to three months.
