80G and 12A Revalidation

In order to claim exemption, a charitable or religious trust or institution, including an NGO, should make an application to the Principal Commissioner of Income Tax or Commissioner of Income Tax online in Form 10A. 

One of the significant changes for the NGO sector is that the last date for revalidation of registration under 12AB, 10(23C) and 80G of the Act has been further extended from 31^st August 2021 to 31^st March 2022.

They have not applied for Revalidation till 31st March,2022 nor till 11th May,2022

Other question is Whether their Old 80G and 12A was valid till 31st Mar,2022 as some donation is received in FY 21-22.

Thanks
