NEW REPORT: We project the Ways and Means Committee's SALT cap ($30K, phasing down to $10K at high incomes) would: - Raise $937B over 2026-35 - Reduce net income for 5.2% of US residents - Lower the Gini index of income inequality by 0.4% Full report in next post:




On April 28th, Governor Greg Gianforte signed House Bill 337, which reduces the state’s top income rate from 5.9% to 5.4% by 2027. The bill also increases the threshold for the lower income bracket and expands the state’s EITC match to 20% of the federal credit.




On SALT: Thanks to PolicyEngine US we can see that families (married w/ at least 1 kid) making $250k or $500k living in NY, NJ, and CA and in the 90th percentile (!) for itemized deductions pay lower taxes under either House or Senate OBBB but with a $30k SALT cap. Link below:

New: Arnold Ventures used PolicyEngine to compare taxes between TCJA expiration and House & Senate reconciliation bills, with $30k SALT cap. Married filers with one child, income of $250k/$500k, and 90th percentile deductions pay less tax under reconciliation bills in CA/NY/NJ.

We're estimating the effect of PolicyEngine US's nonpartisan evidence on legislators' beliefs & voting behavior--and building state legislative district breakdowns of our results. Here's a mockup (the automated demo is...draft): policyengine.github.io/state-legislat…

Enjoyed my conversation with @SVICPodcast about how PolicyEngine uses Claude Code to democratize economic policy analysis. Watch here: youtu.be/4apWdJR9-iY?si…


We used Claude Code to choose our DC office. Built an interactive comparison tool → analyzed 8 coworking spaces → picked the Open Gov Hub. Now we're surrounded by 40+ civic tech and policy organizations in the heart of DC 🧵
