Digital Signature is the mark of approval of electronic information same as we need a regular signature to approve manual documents. Income Tax filing is now an electronic procedure, therefore in order to confirm the authenticity of the information filled, one needs to affix a digital signature on the tax return document. I-T Act 2000 gives a digital signature the importance equivalent to a regular signature.
The attested documents are proof that the taxpayer has filled the form securely without any traces of fraud.
Digital signatures are issued by Certification Authorities. Credentials required for digital signatures are the taxpayer’s name, public key, name of the Certification Authority issuing the signature, expiration date of the public key, the digital signature and its serial number. It is impossible to tamper or claim forgery over a digitally signed document. Further modifications are forbidden post-signing.
Advantages of Digital Signature
One can avail of the following benefits of Digital Signature:
- A Digital Signature is issued by the Certification Authority and any kind of tampering is impossible with the signature.
- Eliminates the need for paper, thus proving to be an eco-friendly option.
- It is easy to track a digitally signed document.

- The E-filing process becomes more efficient and the information has value.
To understand the concept of a digital signature, let’s take a sneak peek at the components of a Digital Signature:
Name: A signature cannot be recognised without a name. The signature holds the name of the person authorizing the document. This reduces the chances of tampering or fraud as the person gives the commitment to the genuineness of the information under his name.
Personal Information: Credentials such as the authorized person’s mobile number, current residential and office address, landline numbers, and email address are equally important with the name on the signature. For user privacy and information security, the credentials are stored in an encrypted (code language) form which cannot be accessed by everybody.
Public Key: Another integral component of a signature. The sole purpose of the key is encrypting and securing a document at the time of authorisation. The key helps in the verification process. Every digital signature has an expiry date, a public key associated with the signature determines its expiration. The public key reveals the period of validity of the signature. Public Key allows resetting of the signature if needed.
Serial Number: Last but not least, the serial number is mandatory for identifying a signature. The serial number is useful for the certification authority that issues the signature. The number is to keep the data organized and with a unique identifier attached to it. The serial number is important for the workability of the digital signature.
