Error when trying to submit a tax return

Last updated: 25 Oct 2020

Have you set up a Personal Tax Account on the .GOV website to receive your tax return?

If not then you must do this before you hit the Submit button in the app. Use the link provided below.

Registering for the Personal Tax Account only takes a couple of minutes and makes submitting your tax return possible.”

It's very straightforward.

Follow this link:

Customers submitting their tax return online for the first time will need to request an activation code, (which activates your account) HMRC will be post the activation code to your home address, it can take up to seven days to arrive.

Once your Activation Code arrives log back into your Personal Tax Account using the above link again, and add the Activation code then save and log out.

Come back to the App, open the "Tax Return" tab, select the 'tax period' then hit the 'Proceed' button. Check over your personal information then hit the green 'Submit to HMRC' button.

Done that and it's still not working?

Make sure you are entering the correct Government Gateway User ID and Government Gateway Password - no typo's. Have you checked the box below User ID before you hit the green 'Submit to HMRC' button?
