What Hometax is

Hometax is the National Tax Service’s online service for tax-related tasks, available on the web and through Android and iOS apps. Its mobile service covers tax filing and payment, applications and submissions, certificate services, inquiries, and reports. Sontax provides an easy estimate calculator for capital gains tax, and businesses can issue electronic tax invoices in bulk by uploading an Excel file. Such uploads are limited to 100 entries; batch issuance options are 50 or 10 depending on invoice type. Mobile login options include joint or financial certificates, simple authentication, mobile ID, fingerprint, and username and password. Some content is available without login, though username login has mobile service restrictions. Issuing electronic tax invoices requires an eligible certificate, and joint certificates and biometric login work only in the Sontax app. The service has tax features for individuals and businesses, including personal tax estimates and business invoice functions. The National Tax Service lists weekday tax consultation at 126 from 9:00 to 18:00. Its privacy policy says personal information and important data are encrypted in storage and transmission. Hometax is free.
