Trying to do my tax return and it says my VAT number is not authorised to access directly to HMRC.
I have been accessing directly for a year at least - I tried to sign up again and got rejected without any help as to why.

Hi Mike

The HMRC authorisation code expires after 18 months, so you will need to
enter a new one from time to time.

If you are seeing the error message "You are not authorised to connect with
organisation..." the most likely cause is that you have logged into the
HMRC website using the wrong Government Gateway User ID. Have you been
issued with more than one Government Gateway User ID? If so, log into
Solar Accounts and open the main window and press Ctrl + F6 on Windows or
Command + Option + R on Mac. (If you are on Windows and your keyboard has
a Fn key, try Fn + Ctrl + F6)

You should then see a message asking if you want to clear your old HMRC
authorisation code - click 'yes' and then try to connect to HMRC again.
When you log into HMRC please check that you are using the correct
Government Gateway User ID.

Thanks Mark for the swift response.
What I don’t understand is that nothing has changed on my computer since my last return.

Hi Mike

Unfortunately HMRC in all their wisdom have decided that even though
nothing has changed on your computer, the authority for us to submit your
VAT returns should expire after 18 months. So you will unfortunately need
to go through the process of entering a new HMRC authorisation code.
