About HomeTax

HomeTax (hometax.go.kr) is the official online tax-administration service of Korea's National Tax Service (국세청), letting individuals and businesses file and pay taxes, issue and manage tax invoices and cash receipts, and request tax certificates without visiting a tax office in person. A companion mobile app, Sontax (손택스), covers many of the same functions from a phone.

Key Features

Full Online Tax Filing: File comprehensive income tax, VAT, corporate tax and more, and pay directly through the site.
Certificate Issuance: Request and print official tax certificates and proof-of-payment documents online.
Pre-Filled Data: For many filings, HomeTax pre-fills known income, health-insurance and deduction data to speed up the process.
Limited English Support: A separate English interface (nts.go.kr/eng) and a dedicated foreign-taxpayer phone line cover key services for non-Korean speakers.
