That link says The government has confirmed that people who can’t work their normal hours because of coronavirus (COVID-19) will still receive their usual tax credits payments.
Those working reduced hours due to coronavirus or those being furloughed by their employer will not have their tax credits payments affected if they are still employed or self-employed.
These customers do not need to contact HMRC about this change. We will treat customers as working their normal hours until the Job Retention Scheme closes, even if they are not using the scheme.
We’ll use the information we hold about the number of hours they normally work.
As LakieLady says, time spent working on building your business still counts, even though it doesn't necessarily produce an income.
I would spend this time thinking about how you could use your expertise to deliver classes online. Perhaps look at websites like outschool.com/ and think about whether you could offer classes through them.
And you could look into making a basic website to advertise your work, for when life returns to enough normality to allow or now if you can deliver something from home.
Also look into how to run a business through Facebook - how much ads cost and how it works, that kind of thing. (You can be really targeted about them).
Even if you don't eventually go for it, even doing that research in is still counted as work if you're self-employed.
If you're doing no work at all then your work could be seen to have ended. But if you're still trying to make your business work (even if you're a sole-trader) then you're still working, albeit reduced hours.
And, you never know, your research could bring you a new source of employment / income.
Lots of people are having to change what they do because of covid. What if the schools don't invite you back in for a couple of years? Start planning now and think how you might offer what you do online, even if in a very different format.
Schools may be being kept open but all the school clubs are closed round here. My kids have just gone off to do their sports clubs for the last time for goodness knows how long.
If you could offer some kind of activity online of the lockdown period that could be very popular.
