HMRC self assessment helpline 0300 200 3310

In a recent development, HMRC caused a stir by announcing the closure of their self-assessment helpline for six months of the year, starting from April this year. However, the decision was temporarily paused less than a day later following a significant backlash.

The self-assessment helpline receives around 5m calls each year, with nearly 4m people staying on through the recorded messages to speak to an HMRC adviser, according to the HMRC quarterly performance figures.

Self Assessment: General Enquiries


If you’ve already contacted HMRC, you can find out when you should receive a reply here.

Ask HMRC’s digital assistant for information about self-assessment. If the digital assistant cannot help you, you can chat live with an HMRC webchat adviser if they’re available.

You can find out more about self-assessment tax returns.

If you need information such as your unique taxpayer reference, employment history, or PAYE tax records, you can access them through your personal tax account or business tax account using HMRC online services. The official HMRC app is also a great way to find this information. If HMRC needs to contact you about anything confidential, they will reply by phone or post.

If you need to inform HMRC about a change in your personal details, you can do so easily. Additionally, you can access videos and webinars to get help with Self Assessment.

If you experience any issues while using HMRC's online services, you can contact their online services helpdesk. This includes problems like difficulty submitting your tax return online, losing your online service username or password, or receiving error messages in your online account or on HMRC forms. Before you call the helpdesk, please ensure you have your national insurance number and a self-assessment unique taxpayer reference.

It's worth noting that this helpline uses speech recognition software. Therefore, you will be asked why you are calling HMRC. If you cannot use speech recognition software, you can find out how to get help from HMRC if you require additional support.

This helpline may also ask you some security questions. Make sure your personal details and address are up to date in your personal tax account or you could fail telephone security. If you do not have a personal tax account, you can create one before you check your details.

HMRC may ask if you want to add voice identification to your account. You can find out more about it in the Voice Identification Privacy Notice.

Telephone: 0300 200 3310

Opening times: Monday to Friday: 8 am to 6 pm

It is closed on weekends and bank holidays.

However, note that this address is only for written correspondence, and you should not use it to file complaints about HMRC.
