How the Affordable Care Act Tax Credit Works

What Happens at Tax Time?

In a perfect world, everything will come out evenly when you file your taxes: You would have been exactly on the mark with the income estimate you gave at enrollment, and the credit due will equal the payments you received. But if the advance payments you received don't add up to the full credit you were due, you'll get a refund. If the reverse happens, you'll owe some money. And if your income doesn't end up being the same as the estimate you gave when you enrolled, the IRS will make the necessary adjustments.

But we all know things aren't always so easy when we're talking taxes. A lot can happen in the months between when you enroll and when the final assessment is made. New babies, new jobs, raises, pay cuts, interstate moves -- they'll all have an impact on your tax credit. This is why the government urges all enrollees to inform the marketplace of any life changes that happen over the course of the year. It's better to make small adjustments to your credit as you go than to get a possibly unwelcome surprise in April.

If it turns out that your income is higher than what you thought it would be -- or if there was another reason you received more credit than you were supposed to -- you will have to repay the IRS. But there is a cap on the amount you'll owe, based on your income not exceeding 400 percent of the poverty line. Individual taxpayers would pay $300 to $1,250, and a married couple would owe between $600 and $2,500 in 2014, based on where they fall on this scale [source: Kaiser Family Foundation]. But if they ended up making more than 400 percent of the poverty line, there is no cap and the full amount would have to be repaid.

And beware, potential tax evaders: If you don't file a tax return for the year you received the credit, you no longer qualify for further ACA tax credits.
