Important reminder!

Licenses for Payroll CS, Trial Balance CS, and Write-Up CS (but not Engagement CS) permanently expired on March 1, 2017.

For details, see CSA license expiration 2017 – frequently asked questions.

Some processes documented in the Help & How-To Center are no longer applicable, due to the discontinuation of these CSA modules.

The Illinois Supplemental Information dialog allows you to enter additional information unique to the Illinois form processing requirements.

Choose Utilities > Payroll Tax Processing and then either click the IL state flag icon on the shortcut bar or choose View > Illinois. Choose Setup > Supplemental Information when the Illinois payroll tax processing window is active.
