Hi there JANECCC1,
It's important that all your payroll information is correctly entered in your books for the pay runs to be done accurately. QuickBooks Online Payroll is a great tool able to help calculate deductions on payroll to then be able to remit them to the government. I can provide some information about payroll liabilities.
If a payroll is run for the January 16th to 31st pay period, but the pay date is February 2nd, then the pay is considered to be a February for the liability payment due to the date of the pay itself.
If you have any other questions, feel free to reach out here.
