We’ve all been there – struggling to remember your HMRC Self Assessment sign in and feeling stuck. Don’t worry, it’s not the end of the world! There are a few quick steps you can follow to get back into your account in no time. Let’s break it down.

How to recover your HMRC Self Assessment sign in details 

First things first: head over to the HMRC services registration page. You’ll see an option that says “Having trouble signing in?” (don’t worry, you’re not alone 😅). Click that, and then select ‘password’ to begin the recovery process.

Now, you’ll be taken to a page that will ask you to confirm your account details. Here’s where the process splits depending on whether you’re a first-time user or a returning one.

First time using your Self Assessment sign in? 

For first-time users, recovery is pretty straightforward! You’ll need your User ID and the email address you signed up with. No worries if you’ve forgotten these – it’s just like resetting your password for Gmail or Facebook.

Once you’ve entered these details, HMRC will send you a fresh password. Once you get that, you’re all set and ready to log in. Easy peasy! ✨

If you’ve submitted a Self Assessment before 

If you’ve used your HMRC Self Assessment sign in before and submitted your tax return, the process is slightly more detailed. Here’s how to proceed:

Choose how you want to receive your new password:

  • Email: if you can access the email address you used when you first registered, choose the “email me my password” option. This will send your password directly to your inbox within minutes. 📧
  • Post: if you don’t have access to your email anymore, don’t worry. Select the option to receive your password by post. Heads up, though – this can take up to 14 days, so if you’re near a deadline, make sure you act fast!  📬

Provide the necessary information:

HMRC may ask for a bit more info to confirm your identity. Don’t stress, it’s usually just basic details like your name, address, and previous Self Assessment details.

Wait for your new password:

Once you’ve selected your preferred method, click ‘Submit’ and wait for your password to arrive. If you choose email, it should be quick. If you opted for post, grab a coffee and wait for your letter! ☕
