They now have a far more detailed picture of who's earning what and it's all updated and digitally stored. It also means that there won't be much in the way of rebates for the 2020 - 2021 tax year because although people are referring to it as a grant it's actually taxable income that goes on the books.
The grants for self employed or companies with premises aren't the best option in all this though. They're just an attractive sounding bauble, and if you think about it you'll see that's true because they were announced quite quickly. Some time after, and causing a bit of pain with HMRC and the banks because of how good it was for us rather than them came the real prize.
If you have the option as a company or sole trader the best option by far is the bounce back loan scheme. Even if you don't need it grab it because you'll never be able to borrow money at such a low interest rate again. As it's a loan instead of adding to your top line, the payments are deducted from your top line so in effect HMRC are making the repayments for you. Obviously you have to meet the payments.
Just as an example if you took the full £50k at 2.5% the repayments will be £800 and odd a month. But that doesn't start for a year. Use the loan to pay off everything else you have as a debt and you'll make a profit on the interest savings and then you'll reduce your outgoings by however much those payments were.
Buy new machinery, van, tools, for the company. Take some as a dividend and buy an investment toy, motorbike, classic car, you could even buy gold with it. Use it as a deposit on BTL property. Basically you have a very rare opportunity to get your hands on a serious chunk of cash that can work for you.
