Our new ACA calculator shows how extending the enhanced premium tax credits would affect households.

An extreme case: A 64-year-old in Fairbanks, AK would gain $655 in 2026 if they earn $61k, but gain $26,861 if they earn $62k.

Happy Tax Day Everyone!

Last year I turned 25 and started a new job in August. Because of my age and earnings in 2024, I qualified for the Earned Income Tax Credit! Using @us.policyengine.org, I can calculate my federal EITC and state EITC, as well as my taxes and net income.

A fun new tool from @maxghenis.bsky.social : a calculator for charitable contributions, including both state and federal effects and interactions with other deductions. Lots of other good bells and whistles. @nicduquette.bsky.social should be into this.
