About Wealth Tax Estimate Calculator

A wealth tax charges a small percentage of net assets above a threshold each year, unlike income tax which charges flows. Because it recurs annually, even a 1% rate consumes a substantial share of a low-yielding asset's return.

Formula

Wealth tax

Tax = (net assets - threshold) × rate

Worked example
