Does this happen to everyone? Every year of self-employment I get letters telling me that I owe money, whether I have already paid my SA or have set up a payment plan. This year I've had to phone up twice after receiving multiple letters, a good two hours each time. Both times I was initially told that I owed a certain amount, but then after I explained I was on a payment plan, being told that they could now see I was on a payment plan... and that the system hadn't been updated, which was why I received the letters threatening to send my case to a debt collection agency. Same thing happened last year. All sorted now and the person I spoke to was very helpful and sorted everything, but is this a good waste of peoples time and money, both at HMRC and sole traders?

Hi, I started a full-time PAYE job on 1st April 24, and with the tax year running to 5 April 24 I wondered whether I still needed to fill out this section of the 23/24 SA form? Not sure how I would calculate 5 days worth of income, tax and NIC?
