For both, taxpayers and tax assessors, a wide-ranging time limit has been provided, which needs to be strictly adhered to. These time limits are not subject to any change, and therefore, they must be followed in letter and spirit. The limits include:
Taxpayers
The taxpayers who have not been able to make an income tax claim on time can ask for a refund, an exemption, a deduction, or a loss carryforward within six years from the end of their original assessment year. This can be better explained with the help of an example. Let us consider that Mr. X was not able to claim a tax refund owing to the poor state of his health, in the financial year (FY) 2017-18 or the assessment year (AY) 2018-19. The expected refund amounted up to a sum of Rs. 5 lakhs. In this case, Mr. X is free to submit an application addressed to the Principal Commissioner of Income Tax or the Commissioner of Income Tax for claiming his refund. The time limit for him to file such an application would be 31st March, 2026.
Authorities
Once the designated authorities receive the application, they are supposed to either accept or reject the applicant's request within a time span of six months. This six months period would be calculated from the last date of the month in which the application was originally received. For instance, if Ms. Y makes a claim for income tax relief on 20th July, 2019, her application will have to be accepted or rejected by the 31st January, 2020.
However, in both such cases, it would be wise to remember that if the income tax relief in terms of refund, deduction, or exemption is granted by a court of law. Then the total period for which the case was under the court's consideration, would not be used to calculate the designated span of six years or six months. Instead, the time limit would be calculated from the date on which a copy of the court's final order is received.
