Both the chancellor and Prime Minister Rishi Sunak have come under fire for refusing to abolish the arrangement for those who live in the UK but pay no tax on their offshore income, with Labour accusing the pair of shielding the super-rich from contributing their fair share.
Claims the move could raise £3 billion ($3.16 billion) per year has been disputed by Mr Hunt, who argues he would rather wealthy people “stayed here and spent their money here” than move abroad.
But he admitted last week he did not get Treasury estimates on the financial impact of ending the status, which the Prime Minister’s multimillionaire wife has held.
The chancellor has now said he has asked officials to look into how much could be raised by closing the loophole, as he cautioned he does not want to sign off on any action that “inadvertently loses us more money than we raise”.
He previously pointed to Treasury uncertainty around the figures “being bandied around”.
Speaking to the Commons Treasury Committee on Wednesday, he denied the suggestion there was “one rule for the rich and another rule for everybody else”.

Presented with some estimates for the value of the move, he said: “I’ve asked for that to be looked at. My point was different actually.
“It is that I understand that non-doms pay in tax … all the taxes that they do pay, around £8 billion of tax a year. So I want to make sure that wealthy foreigners pay as much tax in this country as possible.
“Ireland has a non-dom regime. France has a non-dom regime. These are people who are highly mobile, and I want to make sure that we don’t do anything that inadvertently loses us more money than we raise.”
Mr Sunak’s wife, Akshata Murty, was forced to say in April she would pay UK taxes on all her worldwide income after the couple faced criticism over her non-dom status.
It was estimated that Ms Murty, a fashion designer and the daughter of an Indian billionaire, could have saved up to £20 million in UK tax through the arrangement.

Labour leader Keir Starmer has accused the government of having “gone after working people” with tax rises while doing “nothing about non-dom status”.
In his autumn statement last Thursday, Mr Hunt increased taxes by £25 billion including a freeze on the income tax threshold, meaning millions will end up paying more.
He said on Wednesday he is “very concerned” that it is difficult to be a “modern, dynamic economy” if taxes are “too high”, pointing to debt interest payments and health and care costs as key culprits of higher rates.
It is pivotal to bring down inflation and enact “real public service reform” to remedy this, he said, as he insisted he is a Conservative who “believes you should bring taxes down”.
Mr Hunt argued the Tories could “very comfortably” defend their record on growth, but said he was not sure it was “of value” to set a specific target, as former chancellor Kwasi Kwarteng did.
“But do I agree with the central insight of my predecessor, that the only way we’re going to square the circle of paying for decent public services and being a competitive low-tax economy is increasing our growth rate? He was absolutely right to say that,” he said.

The chancellor froze the thresholds on which income tax rates are paid in the autumn budget, in a move that will drag workers into higher bands as inflation runs high.
He told the committee he did that because “over time, when we can afford to, I want to reduce those headline rates”.
Meanwhile, Mr Hunt said he wished there had not been so much political “instability” in the UK over the course of the last year.
But he told the committee: “I produced an autumn statement that is designed to restore economic stability and consistency of economic policy-making and I hope we can turn a page on all that instability.”
He argued the “primary” causes of the current economic challenges facing the UK are the “two big shocks” of the pandemic and the energy crisis.
“I think it’s wrong to say that this is somehow a uniquely UK issue in terms of the economic instability,” he said.
