PolicyEngine UK

What it does

A static tax-benefit microsimulation model of the UK: parameters, variables and reforms that calculate household tax and benefit outcomes on the Family Resources Survey. A Python package (pip install policyengine-uk) built on PolicyEngine Core; AGPL-3.0. The README says direct microsimulation through it is deprecated for the managed policyengine.py bundle, and results are estimates.
