I'm also worried how we pay this back eventually as I know Sunak has already hinted at it.
Tax rates will rise for all, personal and business, as will VAT, duties, etc. NIC will be extended to other income not just wages.
Those businesses currently exempt from business rates due to small business relief, and who've received the £10k, will almost certainly have to pay more business rates in future - the full exemption given to the smallest businesses will be reduced/removed.
There'll be no single group expected to pay for all the debt being racked up - all forms of tax will rise and be extended to more people, so everyone will pay a bit more, old & young, rich & poor, businesses, employees, pensioners, etc etc. Not only have we the debt to start repaying, but also the extra funding that people are demanding for the NHS.
There's been pressure for the last few decades for lower taxation. After all this, the voters will be forgiving to a government that has to raise taxes across the board - more than at any other time in recent history. The govt have a once in a lifetime opportunity to raise taxes for all as there'll be very little opposition, so they'll have to grab it with both hands. Be very afraid of the next Budget speech!
