Our suggestion would be that you review the ADJUST settings on Federal, FICA, and Medicare Payroll fields, for both Employee and Employer, to confirm that they are properly configured for your pre and post-tax deductions, i.e. Insurance, 401k, etc. Check this first in the Maintain, Default Information, Employees, and then a second time in Maintain, Employees/Sales Reps, as you may have some Employees who aren't utilizing default settings. This has been the most common reason why the Yearly Earnings Report and the 941 do not match. What a lot of people do not realize is that the Yearly Earnings Report is what we call an "actual report" because it reflects what was actually deducted during a Payroll run, while the 941 is what we call a "calculated report" because its values are calculated at the time of running, and as you have found, these values may not match what is on the Yearly Earnings Report.
