Since the enactment of the Affordable Care Act, your taxes are now affected by your health care coverage status. The new policy states that all Americans must have qualified health insurance, though there are a few circumstances in which an exception may apply.
Generally, 3/4ths of the taxpayers who file a return will only be required to check a box on their form that indicates that they have health insurance. This applies to those who are covered under an employee sponsored health plan, or government plans such as Medicare, Medicaid, or military health benefits.
If you purchased health care coverage through the Marketplace, you may have received an advanced tax credit to supplement the cost of your monthly premiums. If you chose to use the tax credit when you purchased your plan, you will have to reconcile the mount you received with the amount you were eligible for on your tax return.
The tax credit is based on your estimated household income, which you supply when you purchase coverage through the marketplace. At tax time, if your actual income is more than you estimated, you may have received a larger tax credit than you are eligible for. If this happens, you may have to pay back the excess credit. You can do so by deducting the amount from any refund you are owed on your taxes, if applicable.
You will receive a document that indicates the amount you received for the credit and other pertinent information in order to file your tax return.
