HMRC - Tax code

If you are employed and pay your tax via PAYE or “at source” (i.e. through your employer), you will have had a tax code assigned to you. The tax code tells HMRC how much they should be charging you.

If you believe you’ve been assigned the wrong tax code, you should contact HMRC as soon as possible to get it changed. Your tax will change from your next pay date, with any excess you’ve incorrectly paid refunded to you.

If you have recently moved back to the UK after having lived abroad, you should check that your tax code is appropriate. Problems can sometimes arise after you’ve started employment in the UK after an extended period of working abroad.

If you need to contact HMRC regarding your tax code, you can do so via Resolver.

• You should always try and resolve any problems with HMRC by talking with the person who has been dealing with you first.
• If this is impossible or has not resolved your issue, you should use Resolver to contact them.
• HMRC operates a tiered complaints system. Complaints will go through two tiers of service.
• If you are still unhappy, you can ask your MP to escalate your complaint to the Parliamentary and Health Ombudsman.

If you believe HMRC has not correctly followed procedure, it's always worthwhile to consider contacting them via Resolver. HMRC may offer compensation for any distress, delay, damage caused, or costs incurred by HMRC (such as the cost of having to hire an accountant).

It's worth knowing that HMRC have the right to take enforcement action to reclaim any debts (under certain conditions).

You should be aware, however, that HMRC field agents have no right of seizure. They might take note of the things you have (your assets), but they can't take any on the spot.

HMRC can level penalties for late payment. It's always worth contacting HMRC if you believe you might have been incorrectly penalised (or if serious circumstances stopped you from paying on time). HMRC will often consider any reasons you might have for late payment.

You should try and correct any mistakes with your tax as soon as possible.
