How the proposed wealth tax works
The Green Party proposes an annual wealth tax of 1% on net wealth above £10 million and 2% above £1 billion. Because it only starts at £10m, the overwhelming majority of people would pay nothing. Read the full explainer and debate on the Green wealth tax page.
Frequently asked questions
Would a UK wealth tax affect me?
Under the main proposal (the Green Party's), only net wealth above £10 million is taxed — 1% a year above £10m and 2% above £1bn. If your net wealth is below £10 million you would pay nothing.
How much would the wealth tax be?
1% a year on the slice of net wealth between £10m and £1bn, and 2% on anything above £1bn. For example, £15m of wealth would pay 1% on £5m = £50,000 a year.
How would a wealth tax work in the UK?
An annual charge on total net wealth — property, pensions, investments and businesses, minus debts — above a threshold. The Green plan sets that threshold at £10m. The 2020 Wealth Tax Commission instead recommended a one-off tax on wealth above £500,000 per person, paid over five years. The hard parts are the same for any version: valuing assets fairly and handling people who are asset-rich but cash-poor.
Has Andy Burnham proposed a wealth tax?
No. The wealth tax proposal on the table is the Green Party's. Burnham's signature tax idea is different — the Proportional Property Tax, an annual 0.48% charge on property values replacing council tax and stamp duty.
Which countries have a wealth tax?
Norway, Switzerland and Spain all levy annual net wealth taxes today, with rates and thresholds far lower than the Green Party's proposed £10m starting point. Most other European countries that once had one — including France, Sweden and Germany — abolished or replaced theirs.
Is there an official UK wealth tax calculator?
No — there is no government wealth tax calculator because there is no UK wealth tax to calculate; the closest official tools cover Capital Gains Tax and Inheritance Tax instead. This calculator models the Green Party's proposed rates so you can see a personal estimate rather than a policy-level revenue projection.
Other parties take different routes to taxing wealth: Labour rules out an annual wealth tax but abolished non-dom status and raised capital gains tax; the Lib Dems would reform capital gains tax instead.
