The biggest advantage is speed of deposit. Refunds are deposited in about three weeks—faster than paper submissions—and there’s no need to stand in line at the tax office or pay transportation costs (according to the National Tax Agency). Creating your tax return is as simple as accessing the National Tax Agency’s “Tax Return Preparation Portal,” entering required information according to on-screen instructions. By linking to the My Number Portal, data such as withholding slips, medical expenses, and hometown tax donations can be imported and filled in automatically.
