Now you can't get Section 80G tax deduction without this TDS-like certificate from income tax portal

Till FY 2020-21, an individual can claim the donation on the basis of the donation receipts at the time of filing income tax return (ITR). However, from FY 2021-22 onwards, the donation can claim be claimed only if an individual enters donation certificate details in the income tax return form. Without the certificate, an individual cannot claim Section 80G deduction.
