The Internal Revenue Service (IRS) is still trying to improve the new Patient Protection and Affordable Care Act (PPACA) tax forms.

The agency posted several new PPACA tax form draft revisions Wednesday, including a new version of Form 1095-C, Employer Provided Health Insurance Offer and Coverage; Form 1094-C, Transmittal of Employer-Provided Health Insurance Offer and Coverage Information Return; and Form 1095-A, Health Insurance Marketplace Statement.

Insurers, PPACA exchanges and exchange users need the forms to keep the PPACA premium tax subsidy and the PPACA cost-sharing reduction subsidy programs going.

The IRS published earlier drafts of the forms this summer. The IRS usually posts just one draft of each form, and its publication draft website tends not to get much attention from anyone other than tax accountants and tax lawyers.

This year, the complicated PPACA tax form and tax form instruction are attracting the eyes of representatives from trade groups, employers and others who are trying to understand how PPACA programs will really work.

It was not immediately clear how the new form drafts differ from the old drafts. The new versions appear to follow the same format and still require users to understand complicated terms and concepts, such as “applicable large employer.”
