I'll explain why you cannot file VAT on a cash basis in QuickBooks Desktop Pro 2020, pacashman.

The QuickBooks Desktop Pro 2020 for the UK has been discontinued. This means there will be no future updates, patches, or new versions of QuickBooks Desktop after June 30, 2023. However, if you're an existing user, you can still use the software for recording purposes.

Since QuickBooks Desktop Pro 2020 for the UK has been discontinued, you cannot file VAT returns directly through the software. If you wish to continue submitting VAT, we must follow HMRC guidelines. In that case, you will need to either transition to QuickBooks Online before the specified date or explore alternative solutions that comply with the MTD requirements.
