Annette Nellen _ SALT Caps

The $10,000 cap on itemized deductions of state and local taxes led a few states to add new “workarounds” such as offering a credit that would reduce state taxes (where the deduction is limited) and converting it to a federal charitable contribution (which is not limited (well it is, but only when donations exceeds about half of your income)). For example, since 2014, California’s College Access Fund takes donations for which the donor gets a 50% credit against their California income tax. On the federal returns that means a charitable contribution for the full amount and a reduced state tax deduction since the credit reduced the donor’s state taxes.

Prior to the Tax Cuts and Jobs Act, at least 18 states had these credit donation arrangements with credits up to 100%, mostly for donations for scholarships to private schools (see Sept. 2018 GAO report). The benefits are funding scholarships, shifting tax dollars to private schools rather than only public schools, and providing a tax break to donors who owe alternative minimum tax (AMT).

After the TCJA, Treasury said it would issue regs to limit the benefit of these credit schemes, taking a substance over form approach in the guidance (Notice 2018-63 (8/3/18)). Proposed regulations were issued in late August 2018 (REG-112176-18 (8/27/18)) & IR-2018-172 (8/23/18)) that basically require the donation to be reduced by the state tax credit claimed or available unless that credit was 15% or less of the amount transferred to the state or local government. This treatment applies to donations made after 8/27/18, regardless of when the state/local tax credit regime was created. Treasury Secretary Mnuchin also issued a press release on 8/23 about the regulations and intent.
