The UK is slowly easing itself out of coronavirus lockdown, although the Government has said that any new freedoms could swiftly be reversed if there is a major uptick in cases.
Boris Johnson has encouraged people who cannot work from home to go back to their workplaces, provided they can do so safely.
With massive government spending rolled out since March to cope with the impact of the coronavirus, the Government fears that the budget deficit could reach £337 billion this year compared to the £55 billion forecast earlier in 2020, the Telegraph has reported.
As a result the Government may be preparing to increase taxes and cut spending after the lockdown to help avoid a debt crisis - although this is far from certain and no decision has been taken yet.
What is National Insurance and could it be raised?
Everyone aged 16 or over who earns more than £183 per week pays National Insurance contributions.
It's used to pay for your state pension and various other state benefits.
Currently the UK's five million self-employed people and freelancers pay less in National Insurance contributions than those on a company's staff.
But Chancellor Rishi Sunak has hinted that the self-employed rate could go up in line with employees - despite his party's pledge in its 2019 election manifesto not to increase national insurance contributions.
He warned in March: “If we all want to benefit from state support, we must all pay equally in future."
Could taxes be raised?
The Conservative Party also promised not to increase income tax or VAT as part of its 2019 general election manifesto, but there have been warnings that it may have to go back on this pledge.
Writing in the Telegraph, tax expert Mike Warburton said that the most likely way in which the Government would raise taxes would be through a "luxury VAT" increase.
This would mean that areas which currently enjoy VAT exemptions - like gambling - could see them removed, and a 25 per cent rate imposed.
But Mr Johnson has been under pressure from Labour and members of his own Government not to raise taxes after the lockdown.
One minister told the Times that higher taxes would be "completely the wrong approach".
He added: “We should be looking at policies that open up the economy — we will need fiscal stimulus. Taxes need to be lower rather than higher.
And former Labour chancellor Lord Alistair Darling, who helped manage the response to the financial crisis of 2008, said that the Government "is going to have to carry" high debt levels.
He added: "When the economy is being deliberately suppressed as it is now for very good reasons, the last thing you want to do is suppress it even further.”
Richard Murphy, a professor of political economy at City, University of London, believes taxes could be raised, but on the wealthier sections of society.
He told the Guardian: "What is clear is that the only fair answer will be that those on the highest incomes, and those with wealth, are the only people who could afford to pick up that bill.
"If anything, everyone else needs a tax cut just to help them survive. Any politician with any concern for tax justice will have to understand this."
Mr Murphy suggested a number of measures along these lines, including removing higher-rate tax reliefs for pension contributions and ensuring that tax rates on income and capital gains are equal.
Can the UK continue borrowing to such an extent in the long term?
The Government has been borrowing at record levels during the coronavirus crisis, and expects to sell another £180 billion in gilts (UK Government bonds) in May and June alone.
But so far there has been little indication that investors are being scared off UK Government debt, even with interest rates low.
This may be because the UK is still seen as a safe investment, with markets around the world suffering the effects of coronavirus.
Public sector pay rises could be put on hold after the pandemic, the Telegraph reported, in a move that would fit alongside any possible tax increases.
The move could raise an extra 6.5 billion for the public finances, a Treasury planning document seen by the Telegraph claimed.
Chancellor Rishi Sunak distanced himself from the document, describing discussions as "premature".
And a Conservative Party source told Politics Home: “We acknowledge that those on the frontline are doing an incredible job at the moment and we’re determined to support them.”
“Public sector pay decisions are made through the usual annual process and recommendations from the review bodies will be considered before awards are announced this summer."
Labour and the Scottish National Party both hit out at the proposal.
Shadow Chancellor Anneliese Dodds said: "A lack of resilience in our public services, caused by ten years of underfunding, has made it harder to deal with the challenge of coronavirus.
"After all our public services and key workers have done to save lives during this pandemic, there must be no return to a society where we lack that resilience.“
SNP finance spokesperson Alison Thewliss said: "Reports that the Tory government is considering imposing more damaging cuts, including freezing public sector pay, will be deeply concerning for millions of people who are already struggling.”
Mr Johnson has said repeatedly that he does not want to return to the austerity policies that characterised public spending in Governments of the last decade.
In response to a question in Parliament from a Labour MP about "the dark days of austerity", Mr Johnson said: "The Government has absolutely no intention of returning to the A-word, which I won't quote. That is not going to be our approach."
The Treasury has been contacted for comment.
