There are a number of ways agents and advisers can contact HM Revenue & Customs (HMRC) for transactions or to get help and support.
In most cases, you can contact HMRC by using the HMRC Online Services, by phone and in writing. In some cases you can also email your queries.
If you are an authorised agent, and you need to contact HMRC about a client's personal Self Assessment tax affairs, partnership matters, PAYE (Pay As You Earn) for individuals (not employers) or tax credit claims, you can also use the Agent Dedicated or Priority Lines to save time.
This guide will show you how to perform the transaction you require, get the information you need, or find the quickest contact route if you need to get in touch with HMRC for more detailed queries. It also covers the benefits and availability of the Agent Priority and Dedicated Lines.

For clients who are in Self Assessment, you can:
You need to be formally authorised by your client and have registered with the Self Assessment for Agents online service to do this.
If your query is more complex or concerns a PAYE-related matter for an individual client, you can check the HMRC website to find the answer to your query.
If you can't find the answer on the HMRC website, you can call the Contact Centre that covers your client's affairs or write to HMRC - see the sections below on how to do this.
If your client is an individual under PAYE and changes their name or address, you can let HMRC know about the changes via email.
You can write to HMRC at the postal address shown on the most recent correspondence you have received from them. If HMRC hasn't written to you or your client recently, please use the following addresses.
For personal Self Assessment queries:
HM Revenue & Customs
PO Box 4000
For queries relating to PAYE for individuals:

HMRC has identified the most common Self Assessment and PAYE queries and created a list of headings that you can use when sending letters to HMRC about your clients' affairs - to help improve the time is takes to process your query.
When you can expect to get a reply
You can find out when to expect a reply to a query or request you've sent to HMRC by using the 'Where's my reply' tool. Please note: this tool covers some of the basic queries that are most popular with HMRC's customers, but there are plans to develop the tool to include more topics.
HMRC Taxes Contact Centres can deal with taxpayer-specific queries from authorised agents. (They can’t help you if you’re calling about employer queries .You must use the dedicated helplines for employers or Construction Industry Scheme.)
By phone you can update or discuss your client's:
You can call the Contact Centre's Agent Dedicated Line on telephone: 0300 200 3311. This line is open from Monday to Friday, 8am to 8pm and Saturday, 8am to 4pm. It's a good idea to use this helpline instead of the general number as it provides tax agents and advisers with a full and fast service.
When you call the Agent Dedicated Line, your call will be:
Please remember that this service is for authorised agents only. If HMRC cannot verify that you are formally authorised to speak to them on your client's behalf, they will not be able to proceed with the call. For this reason, it's important that you don't give this number to your clients.
While HMRC can handle most general business, there are limits and specific exclusions to what they can do by phone.
This helpline is intended for the sole use of agents with queries about DMB - and you can use it to get a priority service.
The telephone number is: 0300 200 3887.
8 am to 8 pm, Monday to Friday.
If you are handling tax credits issues on your clients' behalf, you can call the Agent Priority Line for tax credits on telephone: 0345 300 3943. This line is open from Monday to Friday, 8am to 8pm and Saturday, 8am to 4pm. This line is for agents only.
Calls to this number will be routed to one Contact Centre site. When the call comes through to the Contact Centre, it is identified as an agent call and advisers will have the relevant guidance for verifying and dealing with agents to hand. This should ensure a more efficient service for you when managing your client's tax credits affairs.
If your client's claim is closed down due to a family breakdown and a new record is created, please call the Agent Priority Line to make sure your agent details are transferred to the new claim.
Please note: if your client has a new partner who also wants you to act for them, they must complete form 64-8 before HMRC can discuss both parts of the claim with you.
If, when you contact HMRC, the Contact Centre can't see an agent authority on your client's claim, they will refer your case to a specialist team who will investigate the matter further. Where the specialist team can find your authority it will be restored to the claim within 48 hours. You will be asked to call back after this time in order to continue with your request. Where HMRC can't trace the agent authority, you will be given further advice about what to do next. You may be asked to complete a new form 64-8.
