Introduction

Keeping your HM Revenue and Customers account information updated ensures that tax records and other financial data are accurate. However, some users may discover that they have to change important information such as their name, phone number, or job details saved in their HMRC account. The method a user chooses to update their data depends on what they need to edit and what tax service they use. Typically, updates are made on the HMRC app or the government website, which is ideal for verification and safety purposes. This is why having documentation on hand can make the process much easier.

What You'll Need

The update process usually starts with a login to the government website and applying changes manually in an account. On the other hand, some actions are limited and must be authorized by the HMRC. Also, users may need to provide proof that their new information is verifiable before they are able to complete an update. While this protects users, it also allows HMRC to validate the claims users make about their identities and the paperwork they submit. If you need to edit your details in your personal HMRC account, but you don’t know how to navigate or find the right page, consider following several resourceful instructions to get started.

Visit the HMRC website and log in to your account using your email address and password.

Navigate to the left-hand side of the page, hover your mouse pointer over the horizontal three-dash menu icon to extend the drop-down list, and click the ‘Money and tax’ link.

Review all the steps suggested by HMRC and take the specific actions necessary after you have completed the initial process.

You may want to consider finalizing the update process by taking a few more steps. First, monitor your account to spot any unauthorized changes or access in your account, especially to protect your tax information. Second, review your dashboard to ensure all changes are accurate, confirmed, and verifiable. And third, save all confirmation emails or another form of proof that you handled the update on the website. HMRC may require additional information from you to verify your account ownership and your income tax details. Another factor to remember is that keeping your email address and phone number current makes it easier for HMRC to get in touch with you.

Conclusion

If you experience technical issues while attempting to change your personal and tax details in your HMRC account, there are several options you can use to reach out to the customer service department. The best contact method is via phone during business hours. Please be aware that fees may apply depending on your phone carrier and its guidelines. During your conversation with a human, ensure that you detail the technical glitches you’re encountering to help a specialist find the best solution for your situation. Other options include live chat, X (formerly Twitter), and the help desk (as a last resort).

Why does GetHuman Write How-to Guides for HMRC Problems?

GetHuman has been working for over 10 years on sourcing information about big organizations like Comcast in order to help customers resolve customer service issues faster. We started with contact information and fastest ways to reach a human at big companies. Particularly ones with slow or complicated IVR or phone menu systems. Or companies that have self-serve help forums instead of a customer service department. From there, we realized that consumers still needed more detailed help solving the most common problems, so we expanded to this set of guides, which grows every day. And if you spot any issues with our What do I do if my Xfinity TV or internet is out? guide, please let us know by sending us feedback. We want to be as helpful as possible.
