Fewer U.S. taxpayers are reporting help from a key Affordable Care Act health insurance subsidy on their income tax returns this year—but, for the people who are using the subsidy, the average amount has grown.

Officials at the office of the Treasury Inspector General for Tax Administration (TIGTA) have included those figures in a new batch of preliminary tax return data for the 2017 benefit plan year and the 2018 tax filing year.  TIGTA officials used data from the day the tax filing season started, on Jan. 29, through March 1.

A subsidy refresher

Most premium tax credit subsidy users get the aid in the form of an “advance premium tax credit” subsidy.

Taxpayers sign up for ACA exchange plan coverage each year from Nov. 1 through Dec. 15, The applicants tell the ACA exchange plan managers how much they hope to earn in the coming year.

The exchange system uses the future income forecasts to calculate how much advance premium tax credit subsidy help each consumer should get during the upcoming benefit year.

To reduce the risk of fraud, the payments go to the health insurers providing the coverage, not to the taxpayers.

After the benefit year is over, taxpayers are supposed to use Internal Revenue Service Form 8962 to tell the IRS how much premium tax credit subsidy help their health insurers get, and whether they should get more premium subsidy help from the IRS or send of the excess subsidy help they have received back.

Some Form 8962 filers have received subsidy help only for themselves. Others use the form to report subsidy help provided both for themselves and for other family members.
