Hi there, @Kate76,
Allow me to share some insights about claiming your total VAT on your next return.
QuickBooks is designed to calculate a VAT amount based on the transaction date. It also appears the current period's end date and the balance due for that period on the VAT page.
If you have a monthly VAT period, you'll need to manually type in the transaction date on the next month. For quarterly period, you'll need to manually enter the transaction date on the next quarter. This way, the VAT amount will be reported on your next return.
For more details about managing your VAT in the program, you can check out this helpful article: Getting Started for VAT.
The information above will help claim your total VAT on your next return, @Kate76.
I'm here anytime you have other concerns. Have a great day.
