There are a couple of reasons this may be happening:
- If you have changed your fiscal year, maybe the settings are incorrect. To check, go to Settings > Preferences scroll to the bottom of the Preferences screen and look for the API Fiscal Year Start Date, and Payroll Start Period of Fiscal Year menus. Check that the first shows the correct start date for your fiscal year, and the second should show the month that your fiscal year starts in - if the first month of your fiscal year is July, choose 7 in this menu. Now click Auto-assign Periods at the bottom, and hit Save.
- Are you looking at an employee that started work in the middle of the year? This might affect when the payroll tax expense begins.
