Understanding the Laffer Curve (Simple Explanation)
The Laffer Curve explains how tax rates affect government revenue — and why higher taxes do NOT always mean more money for the government.
👉 0% tax = 0 revenue
👉 100% tax = 0 revenue (no one will work if all income is taken)
Between these two points, there is an optimal tax rate where the government collects the maximum revenue.
🔵 When taxes are low → Revenue increases
People continue working, investing, and earning, so the government receives more tax money.
🔴 When taxes get too high → Revenue falls
High taxes discourage people from working and investing.
Some may avoid or evade taxes.
Businesses shrink or close.
As a result, government revenue declines, even though tax rates are higher.
⭐ The Peak (Best Tax Rate)
At the top of the curve is the maximum tax revenue point — the place where tax is neither too low nor too high.
This is the most effective tax rate for any government.
