Several states have passed — and many more are considering — new tax credits that would reduce tax liability based on donations made by a taxpayer in support of various state, local or non-profit programs. In general, taxpayer contributions to qualifying organizations — including public charities and private foundations, as well as federal, state, local, and tribal governments — are eligible for the federal charitable contribution deduction under section 170. In a previous article, we explained how current law supports the view that qualifying charitable contributions are deductible under section 170, even when the donor derives some federal or state tax benefit by making the donation. We referred to this treatment as the “full deduction rule.”
Some commentators have suggested that Treasury and the IRS could change existing law, whether through new regulations or by issuing a new interpretation of existing regulations, to limit the deductibility of taxpayer contributions when they trigger a state or local tax benefit to the donor. Many legal and administrative concerns are associated with those actions. In this report, we argue that even if the IRS has the legal authority to implement the changes absent new legislation, it should decline to do so.
