Under Income Tax rules, it is mandatory for everyone to link their PAN card with Aadhaar. For this, the Income Tax Department has set a deadline of 30 June 2021. If you do not link your PAN card with Aadhaar by 30 June 2021, then your PAN card will become invalid under Rule 114 AAA(3) of Income Tax Rules, 1962. Due to this you will face many problems.
If your PAN card given for TDS deduction under section 206AA(6) of the Income Tax Act 1961 is not valid or operative, then it is considered that the person has not submitted the PAN details with the TDS deductor and then in this situation The provisions of section 206AA(6) are applicable and in this case your TDS is deducted at 20%.
However, the 20% rate of TDS is applicable only on interest or dividend income on fixed deposits. Or for those things where the rule of TDS is applicable, where it is not so, then this rule will not be applicable.
According to the Income Tax Act, it is the responsibility of the taxpayer to pay the tax. In such a situation, after linking Aadhaar and PAN, you will have to inform the bank, post office for interest income, companies for dividend, mutual fund companies etc. so that not much TDS is deducted.
