Congress recently retroactively repealed IRC Section 512(a)(7), which was enacted by the Tax Cuts and Jobs Act of 2017 and increased unrelated business income tax (UBIT) by amounts paid or incurred for qualified transportation fringes. Because the provision was effective for amounts paid or incurred after Dec. 31, 2017, taxpayers subject to the tax paid it with their 2017 and 2018 returns. Now these taxpayers are entitled to a refund.
