@Barbara1544 You really need to read the government rules on this. The rule below explains when you can and cannot claim expenses. BUT I think it is irrelevant as the previous advice I showed said
You cannot use the scheme if the accommodation is:
- not part of your main home when you let it
So I really don't think the scheme works for you at all.
Do please read the rules on gov.uk as I think it has changed over the years.
1.2 If your gross receipts are more than the Rent-a-Room limit
If your gross receipts are more than £7,500 (or £3,750), you can choose how you want to work out your tax:
Method A
You pay tax on your actual profit — your total receipts less any expenses and capital allowances.
Method B
You pay tax on your gross receipts over the Rent-a-Room limit — that is, your gross receipts minus £7,500 (or £3,750). You cannot deduct any expenses or capital allowances if you choose this method.
HMRC will automatically use your actual profit (Method A) to work out your tax.
If you want to pay tax using Method B, you need to tell HMRC within the time limit. You will continue to pay tax on your gross receipts over the Rent-a-Room limit until you tell HMRC that you want to change back to paying tax on your actual profit (Method A).
If you pay tax using Method B, this automatically stops if your rental income drops below £7,500 (or £3,750) limit.
