If you were one of the millions of Americans who received a tax credit to help pay for healthcare coverage, you could be at risk for a much smaller refund than you expect.

And, that's not all. According to George Brandes, Vice President for Healthcare Programs at Jackson Hewitt®, "more than a third of tax credit recipients will owe some money back, and [that] can lead to some pretty hefty repayment liabilities."

Experts advise those who have received tax credits to contact Healthcare.gov as soon as possible to notify the government of any income changes that have occurred since applying for healthcare. This could help to avoid getting an unwelcome surprise when you file your taxes.

Please note that these changes could also impact insurance premiums; for those taxpayers who count on a hefty income tax return, it may be a better option to preserve what is, for many taxpayers, the largest "payday" of the year.

Experts also warn that filling out returns will only get more complicated with each subsequent year of the Healthcare Reform Law, so it is important to make sure you let a Tax Pro help you get every deduction and credit you deserve and the biggest refund possible.
