Your Income Tax Return is now referred to as an ‘annexure less’ return. This means that no documents or proofs have to be attached along with the return. Many sections of the Act require certificates to be obtained for claiming deductions and tax payers are unsure who to give these certificates to.
The relevant proofs and certificates etc are absolutely essential to be obtained, however those must be kept safely by you in your own records, should the Assessing Officer sends a notice and calls for them or you have to justify them under any circumstance.
Possibly the only paper document you may have to send is your physical ITR-V, that too only if you haven’t been able to e-verify your tax return successfully.
If you do not succeed with the means listed above you need to send the physical ITR-V to CPC, Bangalore.
