How to resolve ProConnect Tax diagnostic Ref 15542 - Illinois use tax might be needed for this return

This article will help resolve the following informational diagnostic, when filing a nonresident Illinois tax return:

• Use tax for Illinois might be needed for this return and is not automatically calculated. In order to implement, please open input Taxes to trigger the use tax. (ref. #15542)

ProConnect Tax doesn't automatically calculate the use tax on Form IL-1040 (line 23 for 2015) for nonresidents. The IL-1040 instructions provide more information about when a taxpayer must pay use tax. 

To automatically calculate the use tax the taxpayer owes:

1. From the Input Return tab, go to State and Local ⮕ Taxes ⮕ IL Taxes.
2. Mark the box Compute use tax for this return to have ProConnect Tax calculate the use tax owed using the tables or a worksheet provided in the IL-1040 instruction booklet. Both tables and worksheet are based on the Federal AGI, or IL-1040, Line 1.

To manually enter the use tax:

1. From the Input Return tab, go to State and Local ⮕ Taxes ⮕ IL Taxes.
2. Enter the amount in the field Use tax enter amount (-1=omit) [O].
