How to contact HMRC

There are several reasons you may need to contact HMRC, you may have received a statement, a request for payment or an incorrect tax code. The most common queries usually relate to Self-Assessment or Corporation Tax.

For individuals, Sole-Traders and Partnerships

HMRC have recently released an online chat function which can be accessed at here.

Following the link under “Ask HMRC online” will allow you to ask simple queries to HMRC’s chatbot. If this is unable to help you can ask to “Speak to a HMRC adviser” and you will be placed in the queue. Your screen will then show your position in the queue and an approximate wait time.

Alternatively you can contact HMRC by phone. The number to call for self-assessment queries is 0300 200 3310.

This line is open Monday – Friday, 8am – 6pm and is closed on weekends and bank holidays.

To call HMRC you will need the following information:

• Your Unique Taxpayer Reference (UTR) number
• Your National Insurance number
• Your address as currently listed in HMRC’s records

If you do not have this information your accountant may be able to provide it for you.

Alternatively you can send a letter with your enquiry to HMRC’s Self-Assessment address:

You do not need to include a street name, city name or PO box when writing to this address.

Once again you will need to include your above information in your letter.
