Which countries have wealth taxes?

Norway (1.1%), Spain (0.2–3.5%), Switzerland (cantonal, 0.1–1%), and a few others maintain annual wealth taxes. France abolished its wealth tax in 2018. Many countries that tried wealth taxes repealed them due to enforcement challenges and capital flight.

What is the difference between wealth tax and estate tax?

Estate tax (also called inheritance or death tax) is levied once on assets transferred at death. A wealth tax is assessed annually on total net worth. Estate tax is a one-time event; wealth tax is recurring.

How is net worth calculated for a wealth tax?

Total assets (investment accounts, real estate, business equity, valuable property, cash) minus liabilities (mortgages, loans). Valuing private businesses and illiquid assets is notoriously difficult and a major practical challenge for wealth taxes.

Would a wealth tax reduce inequality?

Economists disagree. Proponents cite estimates that a 2% wealth tax on the top 0.1% could raise $200B+/year. Critics argue it causes capital flight, reduces investment, and is difficult to enforce. Historical evidence from countries that repealed their wealth taxes is mixed.

What is the wealth tax calculator — estimated net worth tax?

In short

A wealth tax applies an annual percentage to net worth above an exemption threshold. A 2% annual wealth tax on net worth above $50 million would owe $1 million on a $100M fortune ($100M − $50M × 2%). No US federal wealth tax currently exists, but proposals have ranged from 1–8%.

Estimates annual wealth tax liability under various proposed rate structures by applying a percentage to net worth above a given exemption threshold.

How to use this calculator

1Enter your estimated total net worth.
2Enter the exemption threshold (wealth below this is tax-free).
3Enter the proposed annual wealth tax rate.
4The calculator shows taxable wealth, estimated tax, and effective rate.

The formula

taxable wealth=net worth−exemption

tax=taxable wealth×rate

Taxable Wealth = max(0, W − E); Tax = Taxable Wealth × r; Effective Rate = Tax ÷ W × 100

W: — Net worth
E: — Exemption threshold
r: — Tax rate

Worked example

The scenario

$75 million net worth, $50M exemption threshold, 2% wealth tax rate.

gives

The result

Taxable wealth = $25M. Annual wealth tax = $500,000. Effective rate = 0.67% of total net worth.
