Tax Filing Timeline

The entire year is broken up into 4 quarters: 

  • Q1: January - March

  • Q2: April - June

  • Q3: July - September

  • Q4: October - December 

All payroll corrections for current quarter should be completed by the last day of the quarter. For example, Q1 has an end date of 3/31. An announcement will be sent out for a reminder of the timelines for clients. 

The Tax team then works on closing the quarter and filing returns by the end of the month following the last month of the quarter. Example, Q1 filings will be closed and filed by April 30th. Please note, this may vary depending on the form type and agency requirements. 

End of quarter information is generated from the RTS file that is generated from the Tax Team.

Daily tax files are sent through the daily PTS File at 12pm EST everyday automatically. This will include individual payroll information.
