How Do I Update My Illinois Tax Tables?


Where do I find the tax tables?

For IL tax withholdings, you will need publication IL-700-T from the IL Department of Revenue.

Which tables do I use?

Use the "Automated payroll method" described in publication IL-700-T. This method uses a flat percentage for calculating state taxes after deducting any personal or dependent exemptions.

Note that the figures shown in this document are for demonstration purposes only, and may not be current. Please consult the current publication for the most up-to-date information. Though the figures change periodically, the method of calculation should remain the same. If the calculation method has changed for this state please notify the webmaster.
