The Saver's Credit gives you a tax credit of 50 percent, 20 percent, or 10 percent on the first $2,000 in contributions you make to a retirement account. The percentage you get depends on your adjusted gross income (AGI) and tax filing status, but you could potentially claim a credit of up to $1,000—or up to $2,000 if you file jointly with your spouse. You might think of it as a retirement match from the government.
The Saver's Credit is applied directly to your tax bill to reduce the amount of federal income tax you owe. For instance, if your tax bill is $1,000 and your credit is $400, you'd only owe $600. If your tax bill is $1,000 and your credit is $1,000, it's a wash. You'd owe nothing.
What if your tax bill is $500 and your credit is $1,000? Unfortunately, you'd only get the $500 applied to your bill. This is a nonrefundable tax credit, meaning that if your credit is larger than your bill, you don't get the difference.
