Not the most exciting topic, sorry, but hoping the mumsnet hive will have some idea or steer me in the right direction.
I pay tax through PAYE as I'm an employee but I do have additional income on the side - mainly freelance work, including some abroad.
I am a high rate tax payer and have not had any underpaid or overpaid tax in any previous years. 2017-2018 tax year PAYE coding notice did not show any tax underpaid.
Completed my self assessment to declare an additional £1300 earnings (additional to my £54000 salary, already taxed through PAYE), and got a massive shock when the calculation showed as £2,440 owing to HMRC. (Plus another £1200 for 'payment on account'!).
Have tried to call them today but the line was busy and kept cutting me off. And now the office is closed.
I can't figure out what is going on.
I've filled in a self assessment return each year for similar amounts and can't work out why this year the tax owing shows up as greater than additional earnings?
Am trying to submit today so any additional money owed goes out of my PAYE rather than a lump sum I need to pay in Jan.
