Can I submit vat return early

Hi steven-tarry-icl, thanks for posting on the Community

It isn't possible to submit your VAT return early in QuickBooks Online. The return can be submitted from the period end date, and as a general rule, the deadline for submitting is one calendar month and 7 days (after the end of the accounting period). 

Thanks for reaching Intuit support. We'll be here if you have further questions or require additional assistance.
