2023 Schedule AR Instructions 
  
   Purpose of Schedule AR 
  Schedule AR is used to explain the reason for changes on an amended income or franchise tax return. Include Schedule AR with your 
  amended income or franchise tax return when it is filed. 
 
   Who Must File Schedule AR 
  Schedule AR must be filed by individuals, estates, trusts, partnerships, and corporations who are filing an amended income or franchise 
  tax return. This includes amended returns filed on Form 1, 1CNS, 1CNP, 1NPR, 2, 3, 4, 4T, 5S, 6, PW-1, or X-NOL; or Schedule H or  
  H-EZ. 
 
   General Instructions 
  An amended income or franchise tax return is filed only after you file your original tax return. Generally, a claim for refund made on an 
  amended return must be filed within 4 years after the unextended due date of your original return (for example, April 17, 2028, for 2023 
  calendar-year individual income tax returns). However, a claim for refund to recover all or part of any tax paid as a result of an office or 
  field audit may be filed within 4 years after the date assessed. This applies only if you paid the tax, did not file a petition for redetermination 
  (written appeal), and the claim for refund is for an item which was adjusted in the audit. 
   
  If you filed an amended return with the Internal Revenue Service (IRS) or another state, you generally must also file an amended 
  Wisconsin return within 180 days if the changes affect your Wisconsin income, any credit, or tax payable. You should also file an amended 
  Wisconsin return to claim a refund or pay any additional tax due even if you are not amending your federal or other state return. 
   
  Check the space on the upper portion of the first page of the form or schedule to indicate it is an amended return. See the instructions for 
  the form or schedule you are amending for additional information. 
 
   Specific Instructions 
  Check the space(s) for the reason(s) for the change(s) under the  Explanation of Changes on the Amended Return section. Explain in 
  detail the reason for the change in the box below and indicate the line reference(s) from the form or schedule for which you are reporting 
  a change. The following instructions explain the various reasons which may apply to the reason for your amended return. If multiple 
  reasons exist, you may check more than one space to explain the change. 
 
    01 – Dependent change   
  Check this space if there is a change to the number of dependents you are claiming or a change to the information for a dependent 
  claimed. Include a copy of your federal Form 1040 or 1040-SR which includes the changes to the dependent(s). Include a reason for the 
  change in the box below. 
 
    02 – Pass-through entity (partnership, tax-option (S) corporation, estate, or trust) change                 
  If there is a change to the tax return filed by a pass-through entity which affects your income or franchise tax return, check this space. 
  Include a copy of the amended Schedule 2K-1, 3K-1, or 5K-1 with your amended return and a reason for the change in the box below. 
   
  For example, if a pass-through entity changes the amount of income reported on its income or franchise tax return and sends you an 
  amended Schedule 3K-1, file an amended income or franchise tax return to report the change in income and check space 02. 
 
    02a, 02b, and 02c – General information  
  If the change from the pass-through entity is due to one of the reasons provided in space 02a, 02b, or 02c, check space 02 and the 
  corresponding space that applies to your situation. If none of the reasons in space 02a, 02b, or 02c apply to you, do not check any of the 
  spaces. 
 
    02a – Claim for overpayment or credit under sec. 71.745(2)(b) or (3)(b), Wis. Stats.

    member may claim the overpayment within one year after the date the pass-through entity’s audit determination becomes final or within 
    four years of the unextended due date of the pass-through member’s return, as provided in sec. 71.75, Wis. Stats., whichever is later. 
  • You are increasing a Wisconsin tax credit because you are a pass-through member of a pass-through entity that was audited by the 
    department under sec.  71.745, Wis. Stats., and the audit resulted in an increase to a Wisconsin tax credit. Note: According to sec. 
    71.745(3)(b), Wis. Stats., a pass-through member may claim the excess credit not used to offset the pass-through entity’s additional

 •  Within 60 days after the pass-through entity made an election under sec. 71.745(8), Wis. Stats., you are amending your income or

 itemized deductions on federal Schedule A (Form 1040) according to Public Law 115-97 for taxable years 2018 through 2025. These 
 amounts are also no longer allowable as a deduction on federal Schedule A (Form 1040) for Wisconsin purposes. Therefore, a subtraction
