Jennifer Bird-Pollan (Wayne State) presents The State and Local Tax Deduction Cap and Its (Unintended?) Sexist Consequences at Georgia today, as part of its Tax Policy Colloquium Series hosted by Assaf Harpaz:
If two individuals earning similar amounts marry and file jointly, they will owe more in total tax than if they had remained unmarried and filed singly. The income of the second earner spouse is taxed at a higher marginal rate than it would be if that taxpayer were single, making work less financially rewarding. As a result, the consequences of marriage penalties fall disproportionately on women, and the tax system reduces the financial incentive for second earners to work outside the home. The Tax Cuts and Jobs Act introduced a per-return cap on the deductibility of state and local taxes, which further compounds this issue by requiring married couples to share a single deduction cap, while unmarried individuals can each claim the full amount. This creates a new and more straightforward marriage penalty that particularly burdens second earners. Despite this, the policy was enacted without meaningful discussion of its consequences, and ignoring these effects risks reinforcing outdated and harmful gender norms. Ultimately, imposing the cap on a per-return basis rather than a per-taxpayer basis further discourages women from participating in the workforce.
