Have you ever felt overwhelmed by stacks of receipts, worried about losing them, or struggled to find documents for tax filing? Imagine if everything were stored in your mobile device, accessible with just a few taps—no more lost documents or hassle. This is no longer just a vision; the e-Tax system, developed by the Revenue Department, is transforming tax document management like never before. Let’s explore this innovation that will make your life and business operations much easier.
What Are e-Tax Invoices and e-Receipts?
Understanding electronic tax document systems may seem complex, but in reality, they are simply a digital upgrade of the familiar paper documents. This transformation enhances convenience and efficiency and is part of the government’s National e-Payment policy. Let’s explore what each document type means and why it matters.
e-Tax Invoice
An e-Tax Invoice refers to electronic versions of tax invoices, debit notes, and credit notes. These documents are digitally signed or time-stamped in accordance with the standards set by the Revenue Department. They can be legally used as supporting documents for tax deduction and tax filing. e-Tax Invoices reduce the hassle of paperwork and help save physical storage space.
e-Receipt
An e-Receipt is a digital version of a receipt or payment voucher that includes a digital signature, as required by the Revenue Department. It is issued by VAT-registered businesses or those registered under Specific Business Tax (SBT). These e-Receipts are legally valid for financial transactions and can be used as official evidence.
