I understand tax allowances and my deductables for rent, heating, lighting etc but i have bought things like a slow close toilet seat for the toilet used by mindees. of course this is also going to be used by the rest of the house hold. i decorated the loo to make it more child friendly (you get the idea). do i claim 33% of these costs as they were for the business but will be used by the rest of the house hold?
many thanks
