The IRS noted that even in cases where people owe subsidies back, a large majority of them will still get a net refund from the government after they file their taxes. Just a small percentage will have their refund wiped out by their subsidy repayment. The average refund this tax season is $2,900.
Earlier this year, the Obama administration revealed that there were errors on 820,000 so-called 1095-A forms sent out to subsidy-receiving customers of HealthCare.gov.
Those forms detail a customer's monthly premium, the amount they received in subsidies each month and the premium price of a so-called benchmark plan in the region where they live. The benchmark plan's price is used to calculate how much a customer receives in subsidies, and how much of that tax credit they need to claim on their income tax return.
The errors on the forms related to the prices of those benchmark plans. Updated forms, with corrected information, were sent out to all but about 1,500 of the affected customers, according to the administration, which said the remaining forms required additional casework.

The IRS has offered some relief to customers of HealthCare.gov and state-run exchanges who had those kinds of problems, and others, with their 1095-A forms. Details of that relief can be found here.
Also, the IRS has told taxpayers that if they were unable to file an accurate tax return by Wednesday due to problems on those forms, they should file a Form 4868 to request an automatic extension.
Anyone who "received an incorrect Form 1095-A, and filed his or her tax return based on that form does not need to file an amended tax return," according to an IRS spokeswoman. "The IRS will not pursue the collection of any additional taxes from these individuals based on updated information in the corrected forms. Some individuals may choose to file amended returns. Individuals also may want to consult with their tax preparers to determine if they would benefit from amending."
U.S. Sen. Lamar Alexander, R-Tenn., used the occasion of the deadline to blast the Affordable Care Act.
"For most American workers, Tax Day is a frustrating reminder that our federal government is trying to do too much—and it's increasingly dipping into middle-class family budgets to pay for all of its spending," Alexander said. "Obamacare is a prime example. This is the first Tax Day on which millions of Americans will learn the hard way that Obamacare raised taxes in addition to premiums and other health-care costs."
But President Barack Obama last week said he gave his signature health-care reform law an "8 out of 10." His administration has repeatedly touted the benefits of the law, saying it made insurance affordable to millions of people, many of whom were either priced out of the individual insurance market before, or weren't able to enroll because they had pre-existing conditions.
