Saver's Credit. You might be able to report your Roth IRA contributions on form 1040 if you can claim the Retirement Savings Contribution Credit, or the Saver's Credit. The Saver's Credit is for people who earn less than $28,750 if single or $57,500 if married and filing jointly as of 2012. Roth IRA is not tax deductible when you make the contribution. That means you cannot subtract the amount you contribute from your tax return. In exchange, you can withdraw the amount tax-free when you reach 59 1/2-years-old. You also get to take out your earnings tax free.
