For full service payroll I charge $100 per month for up to 5 employees.u00a0 That includes filing the federal and state quarterly returns and year end W2's.If you just need the 941 completed and you have all of your payroll records in order, then the fee would be $50 to prepare the form for you.u00a0 Note that you also need to file a quarterly return with TWC if you have Texas employees.
