We run your payroll, deposit and file your payroll taxes and keep you compliant with federal and Illinois requirements, so your team is paid on time and you avoid costly penalties.
Every pay period, an employer must calculate wages, withhold the correct federal and Illinois taxes, deposit those taxes on time and file regular reports with the IRS, the Illinois Department of Revenue and the Illinois Department of Employment Security (IDES).
Late deposits and filing mistakes can result in penalties and interest. With DATAX, you send us hours and changes, and we handle the rest.
How you classify workers determines which taxes you withhold and which forms you file.
