Hi 9130351972898116,

Thanks for posting in the Community!

If there's no employee paid for the month, you don't need to process a zero pay run as this will not affect your employee's YTD. You can only lodge STP for employees with actual earnings.

For your reference, you can check on this article: Create and lodge a pay event in QuickBooks Online.
