Time to Pay Arrangement problem

I'm eligible to set up a time to pay arrangement online for my SA tax bill, however when I try to do this I get the message "you already have a Payment Plan with HMRC". I had one last year but this closed off some time ago with all payments made on time. I have called the general helpdesk number, the number for setting up payment arrangements, and the technical helpdesk number but nobody knows how to resolve this. I set up my payment plan last year before it became due so I don't think I'm too early, either. Any help much appreciated!

I have been experiencing the same issue. I've been trying to resolve it since July, as I closed my Payment Plan in January 2024. I have already spoken with three different helplines, and I consistently receive the same response: the Payment Plan is closed, it should be fine, and if I need assistance, they can set up a new plan over the phone. Any luck with it?

Hi RobbieD,
If you cannot set up a payment plan online, you can contact our Self Assessment team so we can arrange a plan with you directly.

Thank you.
 

Hi Agnieszka - no I haven't heard anything further and the response from Adminabove isn't too helpful, because the point is that (i) HMRC have an IT issue that nobody seems able or willing to fix, and (ii) people don't want to call a helpline and answer questions about personal finances when they should be able to manage this online.
