Who is responsible for my tax?
Often we think that our employer has a responsibility to collect all the tax due and that we personally don’t have a responsibility to ensure our tax affairs are correct and in order.
The reality is a little different! Pay As You Earn (PAYE) has rules that are operated by employers, however elements are a bit of a guess and involve estimates. This can result in too much or too little tax being collected.
After the end of the tax year finish on 5th April, HMRC reconcile the collected tax by your employer and compare with a more accurate annual calculation which may include additional details relating to other areas that affect your tax. This can result in a refund or a bill.
When starting or changing jobs, it is critical that you provide important information to help get your tax as correct as possible. Give your new employer any P45 that your old job gave you, and if you don’t have one, complete a Starter Declaration. It is essential that you do this when you join and prior to your first pay day. Handing them in later is often too late me you may end up paying too much tax.
It is also important to inform HMRC when you move address or there is a name change for marriage, civil partnership, divorce or other lawful reason. Yes your employer may well have informed HMRC on their regular reports, however, HMRC require you, the tax payer, to inform them of such changes, not your employer (who they will ignore).
