Tax Systems and Optimal Taxation

Interactive 3D simulation of progressive vs flat taxation: watch household income bars get taxed under either scheme, and see the aggregate Laffer curve and deadweight-loss triangle respond live to the tax rate, progressivity and labor-supply elasticity.

Governments face a trade-off between raising more revenue per taxed dollar and shrinking the base people are willing to earn or report. This simulation lets you switch between a flat tax and a progressive schedule, watch each household's tax bite change in real time, and see how the resulting Laffer curve and deadweight-loss triangle move as you adjust the tax rate, progressivity and labor-supply elasticity — the core mechanics behind optimal taxation theory.

⚙ Under the hood

Interactive 3D simulation of flat vs progressive taxation: watch each household's tax bite change on a row of income bars while a Laffer curve and deadweight-loss triangle respond live to the tax rate, progressivity and labor-supply elasticity.
