Hi, hope someone can answer my question. Both me and my wife work for company's and both pay tax and ni contributions through PAYE. We also do a bit of work for a dog walking franchise who pay us into our joint bank account for the dogs we look after. This will exceed £2000 in the next tax year ( 23/24). I also did a bit of work for a builder while I was furloughed which was also paid into our joint bank account. My understanding is that we are both OK for upto £1000 but other people say we are OK upto £2500 each..... I'm confused, do I self assess or not?
