If you have numerous avenues of small amounts of income on a self employed basis, would you have to register as SE for each of them? I'm just thinking for the future really. I'm currently employed and self employed doing the same kind of work (childcare) so I'm registered as a self employed childcare provider and anything I do on a self employed basis goes through that, all my mileage costs, etc. I'm looking at picking up some bits and pieces next year once my maternity ends, hopefully some crafting bits, some childcare (nothing regular, just ad-hoc bits), doing surveys online, doing some other bits online, offering English lessons on a casual basis, etc.
Will I have to register SE for each avenue of income? I'm assuming that I would, but having to do a tax return for each seems a bit much when each avenue would be bringing in only small amounts? Is there a way of declaring the income together? Or would the expenses side be an issue?
