For most UK workers, the Pay As You Earn or PAYE system is how they pay Income Tax and National Insurance they owe on their income. HMRC gives you a PAYE tax code, which your employer uses to work out how much tax to take from your pay, which could include other things like student loan repayments. They then send that money to HMRC before paying the rest to you. In most cases, you don't have to do anything about it yourself. However, it's worth keeping tabs on how much tax is coming out of your pay.

It's possible for your HMRC tax code to be wrong, or for you to be owed a PAYE tax refund on some of your work expenses if your employer doesn't reimburse you for them already.
