Considerations for Manual Payroll in Illinois

Manual payroll processing requires careful attention to detail and up-to-date knowledge of tax rates and filing deadlines. Illinois employers must comply with state-specific payroll tax requirements, including:

• Illinois income tax withholding based on state withholding tables.
• Illinois Unemployment Insurance (UI) tax reporting and payments.
• Accurate calculation of federal and state payroll tax deposits and filings.
