When you buy health insurance through the Affordable Care Act marketplace, you may receive a premium tax credit—money that reduces your monthly insurance payments. This credit is based on your expected income for the year. If your actual income turns out different from what you estimated, the amount of credit you received might not match what you're actually may have access to to. This difference shows up on your tax return and can change whether you owe taxes or receive a refund.

The articles here explain how the premium tax credit works, how to report it correctly on your taxes, and what happens to your refund when your income changes. You'll learn why the IRS asks about your health insurance on tax forms, how to avoid surprises at tax time, and what your options are if you received too much or too little credit during the year.
