LABOUR’S refusal to commit to introducing higher taxes on the super-rich will have infuriated many on the left as the party doubles down on its efforts not to spook businesses and wealthy voters.

Wealth taxes and more progressive rates of income tax on the rich are often key planks of left-wing parties’ policy platforms.

It is tricky to say exactly how much could be raised by raising taxes on very wealthy people, though most estimates put the figure above tens of billions.

Rachel Reeves (below), Labour’s steely shadow chancellor, said her party had no spending plans which would require them to boost Treasury coffers by hundreds of billions of pounds, telling the Sunday Telegraph: “We have no plans for a wealth tax.”

But suppose Labour did want to increase public spending on national infrastructure, the health service, or any number of items that might be high on their agenda if they form the next Government. We took a dig into the data to find out. 

How much could a wealth tax raise?

The most extensive research on this topic carried out recently was conducted by the Wealth Tax Commission, which published its final report in December 2020.

Their research came amid the Covid pandemic in response to questions over how the Government intended to finance the massive debts it had accrued in funding furlough and other spending increases.

It recommended a one-off wealth tax, rather than taxing incomes or spending.

This means individuals would have their wealth assessed and taxed for a one-off sum if they were worth more than a certain amount.

According to the 2020 report, taxing individuals worth more than £250,000 at 1% of their worth annually for a period of five years would generate £387bn for the public purse.

This could be altered in various ways with a progressive regime – where the highest net-worth individuals paying more than their relatively speaking worse-off counterparts.

One model proposed by the commission found that a progressive regime taxing people worth more than £1 million would raise £249bn, while a broader sweep with raids on those worth more than £500,000 would raise slightly less at £248bn.

The report’s authors said that a one-off wealth tax would be better for the economy because it would “not discourage work or spending” when measured against other tax increases like raising income tax or VAT, for instance.
