Payroll settings won't accept correct Employer PAYE reference or Accounts Office reference. Get this message "Something went wrong. Please wait a moment and try again."?

I appreciate the complete details you've provided, @info910.

Stored data can affect your browser's performance and behavior. Let's access your QuickBooks Online account using a private browser.

Here are some keyboard shortcuts you can try:

• For Chrome, press Ctrl+Shift+N. 
• For Internet Explorer or Firefox, press Ctrl+Shift+P.
• For Safari, hold down Command+Shift+N.

If you're able to update your employer information without any error, I'd recommend clearing your regular browser's cache. Also, to check any issues with your browser’s health and its compatibility with QuickBooks Online, you can run the Browser Health Checkup Tool.

I also get the exact same error.

I have used three different browsers and the Quickbooks app and still cannot update my HMRC PAYE reference number, because of this I am now late in subitting my very first payroll through Quickbooks - Never had a single issue like this for the whole 5 years of using 121CloudPayroll and makes me think I made a huge mistake moving to Quickbooks.

Please get this sorted ASAP!

We want this resolved as much as you do, Becky47.

Good work for doing the basic troubleshooting steps. I'd suggest reaching out to our customer care support since you're still encountering the same issue. They have more tools to help you fix this. Here's how:

1. Click Help inside QuickBooks Online. 
2. Select Contact Us.
3. Enter "Error when updating HMRC PAYE reference number" in the description field, then click Let's talk.
4. Select either Start a chat or Get a callback. 

Once it's fixed and you've created your payroll, you can already submit FPS to HMRC. I'll share some articles depending on the payroll subscription:

• Submit FPS to HMRC in QuickBooks Online Standard Payroll (UK)
• Lodging FPS to HMRC in QuickBooks Online Advanced Payroll
