Scotland's Deputy First Minister is raising hopes that a tax cut is on the horizon.
Kate Forbes said rates can not continually increase and all tax decisions should be kept under review before next year's budget.
"If you want to increase taxation you need to expand the number of people or a number of businesses paying tax, and in order to do that you need to attract them here in the first place,” she said, in an interview with The Times.
"So I think people that move here do so for a lot of different reasons, and probably taxes are really low down in the order of issues that they’re looking at. But when it becomes a [point] of difficulty, we should be listening and act accordingly.”
Tax differentials causing concern
A new tax band was introduced at last year's budget in December, taxing anyone earning between £75,001 and £125,140 at 45%. An 1% increase to 48% for the top band (anyone earning more than £125,140) was also introduced.
That led to concerns that some of the country's highest earners would flee Scotland to other parts of the UK to pay less tax.
A worker on £80,000 in Scotland will pay roughly £2,300 more in tax than someone earning the same money in England.
Meanwhile, anyone earning more than £28,850, pays more income tax north of the border than any other part of the UK.
Research has found that most firms in Scotland's financial sector have concerns about hiring at executive or management level due to the Scottish Government's tax policies.
"I do not believe you can continually raise tax", Ms Forbes said.
She added: “I sincerely believe in using taxation as a tool of growth while at the same time guaranteeing public revenue for our public services. So we need to get that balance right.”
Labour's lack of spending 'a massive problem'
While committing to working with UK ministers to deliver for Scotland, Ms Forbes urged a possible incoming Labour government to "turn the spending taps on".
“I care about getting stuff done and I’m here to get stuff done," she said.
“We all know that one of the drivers of economic growth is capital spend on infrastructure.
"You look at other countries around the world, they have accelerated out of Covid at a much faster rate, nearly always because of capital spend … [Sir Keir] Starmer said they won’t turn the spending taps on, if he doesn’t that will continue to be a massive problem for our schools, our hospitals and our roads.
"If he does, then the future is really bright for Scotland."
