I claimed while self employed, it was really straightforward. Given you’re a carer you’ll not have a work commitment so won’t need to worry about being “gainfully employed”, which means they consider you to be working full time on your business and means you won’t have to commit to looking for work.
So you can work effectively part time or around your caring responsibilities. There will be an amount you can earn before your benefits are reduced made up of your personal allowance, an amount that reflects your caring responsibilities, housing costs where applicable. Once you earn more than that your claim reduces by 55p for every pound.
You submit your self employed earning less any business expenses and they work out how much profit, or loss, you’ve made in that month. They then apply the 55p reduction to anything over your entitlement. If you make a loss, that gets carried over to the next month.
So for example if you have an entitlement of £800 and you’re setting up your business you might bring in £100 but have costs of £200 because you have equipment costs, insurances etc. You enter £100 as your income, £200 as your outgoings and so would have a loss of £100. You’d get your full entitlement and they’d carry the £100 loss forward to the next month.
The following month you bring in £400 and have expenses of £50, so your profit would be £350 but they’ve carried your loss forward so they’d take that £100 off your profit and would apply the 55p reduction to the remaining £250. So that month you’d have the £350 profit for that month plus your entitlement less 55% on the £250 profit so £800 less £137.50
So in month 1 you’d get your £800 entitlement and in month 2 you’d get £1,012.50. I found it really easy to submit and calculate and was definitely better off for working.
