Bracket Sandbox

Built for The Economic Explainer · Fiscal modelling in plain numbers

Move the tax brackets and watch the effect on real households and overall revenue — every assumption visible.

Revenue distribution

Where the revenue change comes from

Illustrative designer's view — not official revenue scoring (JCT/CBO) and not tax advice. Tax is applied to gross income with no deductions or credits, so every figure is reproducible from the brackets alone.
