VAT Return box 5 less than box 4 but can't see why

I'm here to help you sort this out, Mick.

Let's run the VAT Exception Details report in QuickBooks Online. This is a way to help make sure that no VAT is missed or duplicated when reporting to HMRC. Here's how:

1. Go to Business overview and select Reports.
2. Type in the report name in the search bar. You can also browse the list.
3. Select the report to open it.

For more details about managing the report, please see this article: VAT Exceptions and Reports.

If you need additional help with your VAT returns, I'd suggest contacting our QuickBooks Support Team. They're equipped with tools to check and determine the cause. Here's how to contact our support:

1. Go to the Help (?) icon at the top.
2. On the Assistant tab, click Talk to a human.
3. Enter your concern in the Type something field, then click the send icon.
4. Click I still need a human.
5. Select Get help from a human.
6. You can either select the Chat with us or Have us call you option.

Additionally, I've added an article that'll help you pay the correct amount of tax and avoid any penalties when filing your VAT returns to HMRC: VAT Codes.
