Thank you for using ezPaycheck payroll software. The difference is the employer-side Social Security Tax and Medicare Tax. You can find them on the employer report too.

As an employer, you need to pay both Employer-side and Employee-side Social Security Tax and Medicare Tax to IRS.

i got a question on quarterly taxes. Per Employer quarterly report, for 1st quarter 2014, my total due to the irs is composed of the following: Fed Income tax Withheld, $3,223.79; Employee SS tax withheld 2749.18 and Employee Medicare Tax Withheld 642.94. Total of these items is $6,615.91. When I go to the Form icon, I clicked on the Form 941 for the first quarter, my total due to federal is $10,008. There is a difference of $3,392.00. What is the reason for the difference?
