I sat in on an HMRC web seminar last week. At the end were Q&A - dozens of them.
Take aways.
You decide whether to claim.
You decide if your work has been adversely affected.
You can continue working.
If you have lost a percentage of your income you can claim.
Questions were asked such as "I've lost 90%; I've lost 50%; I've lost 25%" All those were met with "you may make to claim if your business has been adversely affected."
One person asked "If I have KEPT 95% of income so far can I still claim?" The answer was "you may make a claim if your business has been adversely affected - HMRC have powers to act in cases of fraud - you should do the right thing."
Another asked what proof was needed that you have been adversely affected. The answer was "That you should keep records anyway and that they should show you have been adversely affected."
Now my view of that and if it were me.
Let's imagine that over the previous year I declared £48,000 "profit" after costs. So £4,000 per month. Let's say I look at George for March, April and May and compared with last year I am £800 down in March £2000 down in April and £1200 down in May. I would make the claim if I could show that those losses were due to CV.
I would note that "X,Y,Z" businesses asked me to go on "hold" - that customers 97, 101, 183, 222, 345 had asked me not to call. I would note down any days early on I had not worked due to the Govt announcement. They would be ready next year if the HMRC asked me to explain why I had made the claim.
If I could afford it I would put the grant money to one side in a separate account and treat it as savings not to be touched until the year end.
When I submit my return at the end of the year, let's imagine that instead of a "customary" £48,000 I report £50,500. I would show that as £43,000 earnings plus £7,500 grant.
I might lose more. I might get a mahoosive contract in July (fat chance) - but right now at point of claim I have lost money and so I'll take the grant legitimately.
