How did we decide? We turned office hunting into a software project.

Built an interactive comparison tool with Claude Code to evaluate 8 DC coworking spaces - with real commute calculations using the Google Maps API.

We used Claude Code to choose our DC office.

Built an interactive comparison tool → analyzed 8 coworking spaces → picked @opengovhub.bsky.social.

Now we're surrounded by 40+ civic tech and policy organizations in the heart of DC 🧵

The Prenatal-to-3 Policy Impact Center just launched their new Policy Impact Calculator, which uses @us.policyengine.org for federal and state tax modeling. Great example of research infrastructure enabling better policy decisions for young children and families.

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.

TAXSIM's state and federal calculations have powered 1,200+ papers and projects at BLS, Census, Brookings, and more.

Our emulator will integrate seamlessly—giving researchers full compatibility, open-source transparency, and a new validation dashboard. policyengine.org/us/research/...

🤝 Big news: PolicyEngine and @nber.org
have signed an MOU to ensure researchers worldwide continue accessing critical tax microsimulation tools.

We're building an open-source TAXSIM emulator, combining NBER's 50+ years of tax expertise with modern open-source infrastructure.

🎉 PolicyEngine has been awarded a $300,000 Phase I POSE grant from NSF (Award No. 2518372) to expand our open-source platform, build sustainable governance, and grow our contributor community! https://policyengine.org/us/research/nsf-pose-phase-1-grant

How do energy policies like carbon taxes, LIHEAP, or EV credits impact households? We recap PolicyEngine's open-source tools for analyzing these effects in the US & UK.

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.

The OECD's new report highlights how governments are translating regulations into executable code to make public services more consistent, transparent and efficient. This is exactly why we're building PolicyEngine!

Free, open-source policy analysis tools are essential for evidence-based policymaking. Grateful for NEO Philanthropy's support in expanding access to sophisticated microsimulation modeling.

Great to see @pn3policy.bsky.social continuing to expand the breadth and depth of their Policy Impact Calculator here at APPAM! Among their many sources are tax calculations from @policyengineus.bsky.social.
