Where can I find HMRC reference number please?

Hi there, @Sweet Somethings.

I'm happy to have you here in the Community space today. In case you're referring to the HRMC reference number you entered inside your QuickBooks Online (QBO) company. These are the steps:

1. Access your QuickBooks Online company.
2. On the top-right corner, click the Gear icon and select Account and settings.
3. Select the Payroll tab.
4. Click the pencil icon next to HMRC reference.

In case you haven't entered it inside your company file, you'll want to contact HMRC. This way, they can give it to you, and you can add it to your QBO company. 

Once you receive your HMRC reference number, see this article to learn how you can enter it inside QuickBooks: Tax code notices in QuickBooks Online Standard Payroll.

Moreover, I've got this article to guide you towards completing this year's payroll: Year-end checklist for QuickBooks Online Payroll.

@Sweet Somethings, I got your back if you need help performing specific tasks or have any additional QuickBooks-related concerns. Feel free to mention my name in the comment section below. I'll make sure to get back to you as soon as possible. Take care!
