I've just part completed my self assessment and it is calculating that I owe money (£762) for the tax year 2017-18.
But I'm confused as to why.
My SA is really straight forward - I'm PAYE and everything is taxed through payroll of the Company I work for (I completed an SA because I used to run a business and once you complete one, you end up doing one every year).
In theory, as I'm PAYE, I submit my earnings and literally that's it.
I've ticked yes to being over £50k earner and in receipt of child benefit, and declared my student loan payments for that tax year.
So why would it say I haven't made enough tax?
Could it be the receipt of child benefit and now being over a £50k earner? Or could it be the Student loan?
I have the breakdown if that helps? If the Student loan is deducted via PAYE, do I mention that? It seems like I'm penalised for the Student Loan.
