British finance minister Rishi Sunak will next week promise yet more spending to prop up the economy during what he hopes will be the last phase of lockdown, but he will also probably signal tax rises ahead to plug the huge hole in the public finances. Sunak, who is due to announce a new budget plan on March 3, has already racked up more than 280 billion pounds ($397 billion) in coronavirus spending and tax cuts, pushing Britain’s borrowing to a peacetime record. Prime Minister Boris Johnson plans to lift England’s current lockdown entirely only in late June so Sunak is expected to rely heavily on the debt markets again. His job retention scheme, paying 80% of employees’ wages, will probably be extended beyond a scheduled April 30 expiry date, further inflating its estimated cost of 70 billion pounds. Support for the self-employed looks set to stay too. Businesses are demanding Sunak keep other lifelines, such as exempting the firms hardest hit by the lockdown from property taxes and giving them a value-added tax cut. And calls are growing for an extension of a 20 pounds-a-week emergency welfare increase due to expire in April. The Times newspaper said Sunak would prolong his stamp duty property tax break for three months until the end of June. Sunak hopes that by then Britain will be emerging from its deep freeze thanks to Europe’s fastest vaccination programme. Bank of England Chief Economist Andy Haldane likens the economy to a “coiled spring” primed with the savings that households have built up after being stuck at home. A strong recovery would mean a jump in tax revenues, doing some of the Treasury’s job of fixing the public finances. Rupert Harrison, an aide to former finance minister George Osborne, said Sunak should not try to slash Britain’s 2.1 trillion-pound debt mountain, equivalent to 98% of GDP - a ratio unthinkable for decades. Instead he should write new budget rules tied to the cost of debt servicing, which is close to record lows. “We can safely carry higher levels of debt than before,” Harrison told a webinar organised by Onward, a think-tank. But the scale of Britain’s borrowing is raising questions about how long Sunak and Johnson can stick to their promises not to raise key taxes, made to voters before the 2019 election. BROKEN PROMISES? The huge costs of tackling the worst of the coronavirus pandemic are likely to ease in the months ahead, meaning this year’s 400 billion pound budget deficit should narrow. But Britain is probably on course to be stuck with a gap of 60 billion pounds between revenues and day-to-day spending by the mid-2020s, the Institute for Fiscal Studies think-tank says. In a nod to that, Sunak is expected to start raising Britain’s low corporation tax rate. The Sunday Times said the rate would rise steadily to bring in an extra 12 billion pounds a year by the time of the next election, due in 2024. Other options include ending a freeze on fuel duty increases which has been in place since 2012 and looks at odds with Britain’s plans to be carbon net zero by 2050. But higher fuel prices now would hurt the haulage industry, already struggling with Brexit-related disruption, and could alienate working-class voters who backed Johnson in 2019. Higher capital gains tax or lower pension incentives would anger lawmakers in Johnson’s Conservative Party. David Gauke, a former deputy finance minister, said the only big revenue-raising options were the ones that Johnson has promised not to touch - income tax, VAT and national insurance contributions. “In the end, they are going to have to say, sorry we just can’t responsibly maintain that manifesto commitment,” Gauke told the Onward webinar.
