What is e-Tax?

Electronic Tax (e-Tax) is a way of converting and generating tax invoices into electronic files; including debit notes, credit notes and payment receipts. A digital signature is embedded into the converted e-Tax files prior to being sent to the consumer and submitted to The Revenue Department in the required time frame.
This process significantly reduces paper use and increases efficiency in the process of generating, sending and submitting tax invoices. Brainergy aims to promote and fully supports e-Tax by offering our own service called SMART Tax.

What is the difference between Electronic Signature and Digital Signature?
Electronic Signature is a way of imprinting a symbol or a signature onto a document for verification. The symbol or signature may come in forms such as a photograph of a signature, a scanned copy of a signature, a signature traced out by a computer mouse or stylus, email signatures, clicking on “I Agree” in an electronic form, etc.
Digital Signature is a subset of Electronic Signature. It also comes in electronic form, but is generated with added security properties as follows:
- Signer Authentication – enables the ability to track who the document authenticator is.
- Data Integrity – enables the ability to check whether if the document and its contents has been altered after authentication.
- Non-repudiation – assures the authenticator cannot deny signing of the document, as it can be tracked who the authenticator is.
