Overview 

If you are a partner, member, or shareholder in certain pass-through entities, you may need to adjust your Wisconsin state return for entity-level additions or subtractions. These adjustments are reported using the WI – Entity Level Additions/Subtractions form. 

What is Entity-Level Additions and Subtractions? 

Wisconsin requires taxpayers to adjust their income for certain entity-level tax items that are passed through from partnerships, S corporations, or other entities. 

• Entity-level additions increase your Wisconsin taxable income when the entity reports income or expenses that must be added back to the individual level. 

• Entity-level subtractions decrease your taxable income when Wisconsin law allows deductions or exemptions related to the entity’s activity. 

These adjustments ensure that income is properly reported and taxed at the individual level after accounting for Wisconsin-specific tax rules. 

Who Should Include This Form? 

You should complete the Entity Level Additions/Subtractions form if: 

• You are a partner, shareholder, or member in a pass-through entity that files a Wisconsin return. 

• Your Schedule K-1 or other entity reporting shows Wisconsin-specific additions or subtractions. 

• You need to adjust your Wisconsin return for entity-level activity such as depreciation differences, non-deductible expenses, or tax-exempt income.
