I decided to contribute to a Roth IRA after filing my return. If I take the standard deduction and didn't file a schedule A for itemized deductions, do I still need to file an amended return to report the Roth contribution? I don't see any forms on the amended return that would go to the IRS stating the Roth contribution
You wouldn't get a deduction for the ROTH contribution, but it's possible you could use the ROTH contribution as a basis for a Retirement Savings Contribution Credit. You can review the information below to see if that applies to you, and, if it does not apply to you, as long as you are eligible to contribute to a ROTH (under the income limits), then there is no reason to amend to report anything.
