Is a voluntary contribution irrevocable?
Yes. The voluntary contribution can only be made on the original return. Contributions cannot be made or reversed on an amended return. Example: John made a voluntary contribution on his current year tax return. On December 30, he changed his mind and tried to request a refund of the contribution he made. Since the tax return had already been filed, John cannot revoke his contribution. Therefore, he will not be entitled to a refund.
