Hi @marshallplumbing,
Yes, this can be done inside QuickBooks Online (QBO). Let me walk you through with the steps:
- From the Gear icon, select Account and Settings.
- Click the Payroll tab.
- Search for the Online filing with HMRC section, then edit the Gateway user ID and password as necessary.
- Click Save, then click Done.
When you're ready to submit a VAT return to HMRC, you can refer to the link I provided. It's a step by step guide on how you can submit a VAT return in QBO.
For any other questions, feel free to post them in the comments below. I'll be sure to get back to you.
