Hi there, Accounting1001. The changes you made will only take effect on the next calendar quarter (e.g., April 1st). Because the system generates tax liabilities the moment you process a paycheck, any payroll run before the update remains 'locked' (Q1: Jan-March) into the previous bi-monthly schedule to ensure CRA remittance rules.
Changing the master setting will not retroactively combine existing liabilities. Please double-check your Federal Tax Information to verify your setup. To do this, go to the Gear icon, then select Payroll Settings, and click on Federal Tax (CRA). Next, click the edit to view your PD7A form settings.
Check if the 'Monthly' status has an effective date of April 1st, 2026. If it does, you must continue remitting bi-monthly for the remainder of March. Once the new quarter begins, the system will automatically group your April payrolls into a single monthly payment.
Please feel free to leave a post below if you need further assistance.
