2023 Form 1CNS Instructions 
 
  A tax-option (S) corporation having two or more qualifying nonresident shareholders uses Form 1CNS to 
  report and pay  the  Wisconsin income  tax owed by  those  shareholders.  In order to file Form  1CNS, the 
  corporation  and  its  shareholders  must  agree  to  the  rules  prescribed by the  Wisconsin  Department  of 
  Revenue set forth in these instructions. 
 
  The composite return replaces the separate Wisconsin income tax return, Form 1NPR, that otherwise would 
  be filed by each of the qualifying and participating nonresident shareholders. 
 
  Note: Filing the Form 1CNS does not relieve the entity from filing tax returns; the entity is still required to file 
  Wisconsin income or franchise tax returns.

  Who May Participate in Composite Return 
 
  A tax-option (S) corporation that derives income from business transacted, services performed, or property 
  located in Wisconsin may file Form 1CNS on behalf of its nonresident shareholders who derive no taxable 
  income or deductible loss from Wisconsin other than their pro rata shares of the Wisconsin tax-option (S) 
  corporation income or loss. 
 
  Who May Not Participate in Composite Return 
 
  A tax-option (S) corporation cannot file Form 1CNS on behalf of its nonresident shareholders in a taxable 
  year  that  the  tax-option  (S)  corporation  makes  an  election  to  pay  tax  at  the  entity  level  under  sec. 
  71.365(4m)(a), Wis. Stats. 
 
 IC-157 (R. 3-24) 

                                Wisconsin 2023 Form 1CNS Instructions 

 A shareholder cannot participate in this composite return in any of the following cases: 
 • The shareholder is an entity and not an individual. However, if the shareholder is an LLC treated as a 
   disregarded entity or a grantor  trust  that  is not required to  file  Form 1041  for federal income  tax 
   purposes, the single member of the LLC or grantor of the grantor trust is deemed to be the shareholder for 
   purposes of the Form 1CNS eligibility requirements. 
 • The shareholder is an electing small business trust (ESBT). 
 • The shareholder files their individual income tax return on a fiscal year basis. 
 • The shareholder is a Wisconsin resident during any part of 2023. 
 • The  shareholder  derives  taxable  income  from  Wisconsin  in  2023  other  than  their  pro  rata  share  of 
   income or loss from one tax-option (S) corporation. 
 • The shareholder wishes to claim any tax credits or amounts deductible as itemized deductions. 
 • The  shareholder  is  required  to  file  Wisconsin  Schedule  RT, Wisconsin  Related  Entity  Expenses 
   Disclosure Statement, to report interest expenses, rental expenses, management fees, and intangible 
   expenses that result from related party transactions between the shareholder and corporation. 
 • The shareholder has already  filed or plans to  file a  2023  Form 1NPR,        Nonresident and Part-Year 
   Resident Wisconsin Income Tax. 
 • The shareholder filed Form PW-2 and has been approved by the department to be exempt from pass- 
   through withholding for the tax-option (S) corporation's current taxable year. 
 
 Shareholders who are full-year Wisconsin residents must file Wisconsin Form 1. Part-year resident share- 
 holders and nonresident shareholders who may not participate in Form 1CNS must file Wisconsin Form 
 1NPR to report their own income. 
 
 What Income Is Reportable on Form 1CNS 
 
 Report each qualifying and participating shareholder’s pro rata share of taxable income or loss for the tax- 
 option (S) corporation’s taxable year ending between January 1, 2023, and December 31, 2023, on a 2023 
 Form  1CNS. (Note: For a tax-option (S) corporation on a 52-53 week  taxable year, the  taxable year is 
 considered to end on the last day of the month closest to the end of the period.) 
 
 When to File 
 
 Form 1CNS  is due  April  15,  2024. A late filing fee of $50  will be charged  for returns not  filed timely; 
 however, the following extensions of time to file are available: 
 • Any extension allowed by the Internal Revenue Service for filing the tax-option (S) corporation’s federal 
   return automatically extends the due date of Form 1CNS to 30 days after the federal extended due date, 
   provided a copy of the federal extension is included with Form 1CNS. 
 • The corporation may receive an extension of time to file Form 1CNS by including a statement with Form 
   1CNS which has the following information: The federal extension provision being used and the name, 
   address, and signature of each shareholder covered by the extension. 
 • Disaster  Relief  Extension. If  you  are  filing  under  extension  because  of  a  federal  or  state  disaster, 
   include a statement indicating which disaster extension you are using and include it with your return. 
 • Extensions to  file allowed by  the Internal Revenue Service  to individual shareholders will also give 
   Wisconsin extensions  to those particular shareholders, provided a copy of the federal extension is 
   included with Form 1CNS. Other shareholders who don’t have an extension may be subject to late filing 
   fees and delinquent interest if Form 1CNS is filed after April 15, 2024. A separate $50 late filing fee may 
   be imposed on each shareholder who doesn’t have an extension.

 Filing Methods 
 
 Tax-option (S) corporations are required to file Form 1CNS electronically through the Federal/State E-Filing 
 Program or through My Tax Account, the department's free electronic filing application. 
 
 If  the  requirement  to  file  electronically  causes  an  undue  hardship,  you  may  request  an  electronic  filing 
 waiver by filing Form EFT-102, Electronic Filing or Electronic Payment  Waiver Request. If the waiver  is 
 approved, mail your return to: Wisconsin Department of Revenue, PO Box 8965, Madison WI 53708-8965. 
 
 Internal Revenue Service Adjustments and Amended Returns 
 
 Wisconsin law requires the following information to be provided to the department: 
 • Adjustments made to a shareholder’s federal tax return by the Internal Revenue Service that affect the 
   Wisconsin net  tax payable, a Wisconsin net operating loss carryforward, or a Wisconsin capital loss 
   carryforward must be reported within 180 days after they become final. 
 • Changes made on a shareholder’s amended return filed with the Internal Revenue Service that affect 
   the Wisconsin net tax payable, a Wisconsin net operating loss carryforward, or a Wisconsin capital loss 
   carryforward must be reported on an amended Wisconsin return within 180 days after the filing of the 
   amended federal return. 
 
 Either the corporation or the shareholder must report this information as follows: 
 
 When corporation must report this information. The corporation must file an amended Form 1CNS to 
 report federal adjustments or amendments to a shareholder’s federal return that affect the amount of the 
 shareholder’s income or tax reported on the shareholder’s original Form 1CNS. 
 
 To amend Form 1CNS, file another Form 1CNS and check the space at the top of the form indicating that it 
 is an amended return.  Included  with the amended return a copy of the final federal audit report if  the 
 amended return is being filed as a result of a federal audit. Otherwise, include Schedule AR to explain the 
 changes made and the reasons for the changes. 
 
 When shareholder must report this information. The shareholder must file an amended Form 1NPR to 
 report federal adjustments or amendments to the shareholder’s federal return that affect Wisconsin items of 
 income, loss, or credit other than the tax-option (S) corporation income or loss reported on Form 1CNS. 
 
 To amend Form 1NPR, file a Form 1NPR and check the designated line indicating that it is an amended 
 return. Include any tax-option (S) corporation income or loss previously reported on Form 1CNS. Include 
 with the amended return a copy of the final federal audit report if the amended return  is being filed as a 
 result of a federal audit. Otherwise, include Schedule AR explaining the changes made and the reasons for 
 the changes. If claiming credit for taxes previously paid on your behalf on Form 1CNS, include a statement 
 indicating the corporation’s name and federal employer identification number and amount of tax paid. 
 
 Refunds, Assessments, and Correspondence 
 
 By filing Form 1CNS, the signing shareholder declares that the tax-option (S) corporation has a power of 
 attorney or other written authorization from each qualifying and participating shareholder to file a composite 
 return. The department may mail refund checks, assessments, and all correspondence to the corporation at 
 the address indicated on Form 1CNS.

 must agree to be responsible for the payment of any additional tax due, interest, and penalties, as finally 
 determined. The department may contact the individual shareholders.

 Wisconsin Taxation of Tax-Option (S) Corporation Income for 
 Nonresidents 

 Nonresident Individual Filing Requirements 
 
 Nonresidents of Wisconsin having $2,000 or  more of  Wisconsin gross income during  2023  must file a 
 Wisconsin income tax return. A nonresident who is married  has a Wisconsin filing requirement  if the 
 combined Wisconsin gross income of both spouses is $2,000 or more. 
 
 Gross income means all income (before deducting expenses) reportable to Wisconsin which is received in 
 the  form  of  money,  property,  or  services.  Gross  income  includes  a  pro  rata  share  of  tax-option  (S) 
 corporation gross income (before deducting expenses) as reported on Wisconsin Schedule 5K-1, line 20, 
 column e. 
 
 If gross income (or the combined gross income of spouses) is less than $2,000, a Wisconsin income tax 
 return  is  not  required.  However,  if the  shareholder  has  tax  withheld  by  the  corporation,  the shareholder 
 should file a Wisconsin income tax return (Form 1NPR or Form 1CNS) to obtain a refund of the amount 
 withheld. 
 
 Shareholder’s Share of Income Taxable to Wisconsin 
 
 All  tax-option  (S)  corporation  income  earned  in  Wisconsin  is  taxable  to  nonresidents  of  Wisconsin.  If  a 
 corporation does business only in Wisconsin, a nonresident’s share of its entire net income is taxable by 
 Wisconsin. If a corporation does business in more than one state, the amount attributable to Wisconsin 
 based on apportionment or separate accounting, as appropriate, is taxable. A unitary, multistate corporation 
 generally  must  determine  the  amount  attributable  to  Wisconsin  using  the  apportionment  method.  A 
 nonunitary, multistate corporation must use separate accounting. 
 
 Because  all  tax-option  (S)  corporation  items  retain  their  character  as  business  income  or  loss,  a 
 nonresident shareholder’s share, as well as a resident’s share, of a tax-option (S) corporation’s intangible 
 income, with certain exceptions, is taxable by Wisconsin.

                           Wisconsin 2023 Form 1CNS Instructions 
 
 Interest on United States government obligations, bonds issued by the government of Puerto Rico, Guam, 
 the Virgin Islands, or (for bonds issued after October 16, 2004) the Government of American Samoa, and 
 certain state and local government bonds isn’t taxable to the shareholders for Wisconsin purposes. 

 Withholding Requirement for Tax-Option (S) Corporations Having Nonresident Shareholders 
 
 A tax-option (S) corporation that has one or more nonresident shareholders is generally  required to pay 
 pass-through entity  withholding tax on its distributable income which is  allocable to  the nonresident 
 shareholders. However, withholding is not required on behalf of the following nonresident shareholders: 
 • A shareholder who is not otherwise subject to Wisconsin income or franchise tax (such as a 501(c)(3) 
   organization with no unrelated business taxable income). In this case, the tax-option (S) corporation may 
   rely on a written statement from a shareholder explaining why the shareholder is exempt from Wisconsin 
   tax. 
 • A  shareholder whose share  of  income attributable to Wisconsin  from  the  tax-option  (S)  corporation 
   is less than $1,000. 
 • A shareholder who completes Form PW-2, Wisconsin Nonresident Partner, Member, Shareholder, or 
   Beneficiary Pass-Through Withholding Exemption Affidavit, and provides a copy of the exemption letter 
   received from the department to the tax-option (S) corporation. See Form PW-2 instructions for details. 
 • A shareholder who provides an exemption letter to the tax-option (S) corporation. 
 
 Tax-option (S) corporations are required to make quarterly estimated withholding tax payments. In addition 
 to  the  quarterly estimated payments, a  tax-option (S) corporation is still required to file  Form  PW-1, 
 Wisconsin Nonresident Income or Franchise Tax Withholding on Pass-Through Entity Income, on an annual 
 basis and pay any additional withholding tax due.  
  
 For more information about pass-through withholding, see the Form PW-1 instructions. 
 
 Specific Instructions for Form 1CNS 

 Line-by-Line Instructions 
 
 Fill in Schedule 2 of Form 1CNS first; then enter the totals from Schedule 2 on Schedule 1. 
 
 The name and address information should be written on single lines. Do not stack the information on the 
 lines. If more room is needed, abbreviate where possible. Exception: The information may be stacked in 
 column (A) of Schedule 2. 
 
 Do not write "None" on the amount lines if there is not an entry for the lines. Instead, leave the lines blank. 
 
 Schedule 2 Instructions 
 
 ■ Columns A Through C. Name and Address, Social Security Number, and Pro Rata Share                – Enter 
 the information requested concerning the nonresident shareholders who are participating in this composite 
 return. Complete names, addresses, and social security numbers are required. Prepare and  submit a 
 separate schedule, if necessary, if there are not enough lines provided on Schedule 2. 
 
 Notes:  
   •  If both spouses are shareholders and they wish to compute their tax jointly, use only one entry line in 
    Schedule 2. Enter both names on that line in column A, list both social security numbers in column 
    B, both ownership interests in column C, and combine their amounts in columns D1, D2, and E for 

                                                    5 

                           Wisconsin 2023 Form 1CNS Instructions 
    purposes of determining the tax to enter in column G.  
     
    Exception:      If only two shareholders are included on the composite return and the shareholders are 
    married filing a joint return, enter the name and social security number of each spouse on separate 
    lines but combine their amounts for the remaining columns onto one line.  
   •  If a nonresident shareholder is a limited liability  company  (LLC) or grantor  trust treated as  a 
    disregarded  entity,  the  owner  of  the  LLC  or  grantor  of  the  grantor  trust  is  deemed  to  be  the 
    shareholder for purposes of filing Form 1CNS. When reporting a nonresident shareholder's allocated 
    portion of income or loss on Schedule 2 of Form 1CNS, the same social security number (SSN) 
    cannot be reported more than once in column (B). If an individual is an owner of an LLC or grantor of 
    a grantor trust treated as a disregarded entity and both are nonresident shareholders of the same 
    tax-option (S) corporation, all income or loss allocated to the individual and the disregarded entity 
    must  be  combined  when  reporting  on  Schedule  2  of  Form  1CNS.    For  more  information,  see 
    Wisconsin Tax Bulletin 218 (July 2022, page 3). 
   •  If the shareholder is a foreign individual who does not have a taxpayer identification number (TIN), 
    the  shareholder  must apply  for  a  TIN  with  the  Internal  Revenue  Service (IRS).  Do  not  file  Form 
    1CNS until the IRS issues the shareholder a TIN. 
 
 ■ Column D1. Shareholder’s Share of Wisconsin Tax-Option (S) Corporation Income (Loss) – Using 
 the amounts entered on Schedule 5K-1, column e, compute each shareholder’s Wisconsin net income or 
 loss to enter on Schedule 2, column D1. 

 The net income or loss may not agree with the total of the amounts on Schedule 5K-1, column e, for the 
 following reasons: 
 • Only  those separately  stated  deductions  of  the  tax-option  (S) corporation  that  are  deductible by the 
   shareholders in computing federal adjusted gross income are allowed as deductions on Form 1CNS. For 
   example,  contributions  reported  on  Schedule  5K-1,  line  12a  are  not  allowed.  Use  the  Wisconsin 
   apportionment percentage to allocate allowable deductions to Wisconsin. 
 • Passive activity losses may be limited as provided in the Internal Revenue Code. 
 • 30% of the net capital gains realized on assets held more than 1 year is excludable from income, except 
   that 60% of net capital gains realized on certain assets used in farming (i.e., farm livestock, farm real 
   property, depreciable farm property, or farm equipment) is excludable from income. 
 • The net capital loss deduction is limited to $3,000. 
 • A lower-tier entity made an election to pay tax at the entity level under sec. 71.21(6)(a), Wis. Stats. A 
   lower-tier entity is a pass-through entity (i.e. partnership) that is directly or indirectly owned by the tax- 
   option (S) corporation. 
 
 If any of these differences apply,  submit a schedule with Form 1CNS showing the computation of net 
 income. 
 
 If  the  shareholder  is  claiming  a  net  operating  loss  carryforward,  prepare  a  schedule  showing  the 
 computation of the carryforward and submit it with your Form 1CNS. Caution: An individual generally must 
 have a federal net operating loss in order to have a Wisconsin net operating loss. For exceptions, see the 
 tax  release  titled  “Wisconsin  Net  Operating  Loss  When  There  Is  No  Federal  Net  Operating  Loss”  in 
 Wisconsin Tax Bulletin 70 (January 1991, page 19). 
 
 ■ Column D2. Shareholder’s Share of Wisconsin  Gross  Income  –    For each  shareholder,  fill in the 
 amount reported on Schedule 5K-1, line 20, column e. If the amount on Schedule 5K-1, line 20, column e, is 
 $2,000 or more, the shareholder has a Wisconsin filing requirement and must file using either Form 1CNS 
 or Form 1NPR.

                           Wisconsin 2023 Form 1CNS Instructions 
  
 ■ Column  E.  Federal Adjusted Gross Income  –  For each shareholder, enter the shareholder’s federal 
 adjusted gross income from federal Form 1040 on Schedule 2, column E. 
 
 Note: If this information is not available, you  must compute the shareholder’s Wisconsin  tax using the 
 alternate method described in the instructions below for Schedule 2, column G. 
 
 ■ Column F. Filing Status – For each shareholder whose federal adjusted gross income was reported in 
 column E, enter the appropriate designation for the shareholder’s filing status in 2023: S for single, H for 
 head of household, MFJ for married filing a joint return, and MFS for married filing a separate return. 
 
 Note: To use the joint return filing status, the shareholder’s spouse cannot have any income taxable by 
 Wisconsin  other  than  income  or  loss  from  this same  tax-option  (S)  corporation.  If  both  spouses  are 
 shareholders  and  they  wish  to  compute  their  tax  jointly,  combine  their  net  incomes  for  purposes  of 
 determining the tax to enter in column G. 
 
 Do not  fill in column F for any  shareholder whose tax must be computed under the alternate  method 
 explained below. 
  
 Column G. Tax    – If the shareholder’s federal adjusted gross income has been entered on Schedule 2, 
 column E, figure the tax on the income in column D1 by using the tax computation worksheet on the last 
 page of these instructions. Don’t use the tax tables in the Form 1 or Form 1NPR booklets. No standard 
 deduction or itemized deductions will be allowed for purposes of this composite filing. 
 
 Alternate  method  of  computing  column  G. If  the  shareholder’s  federal  adjusted  gross  income  is 
 unknown, multiply the Wisconsin income in column D1 by 7.65% (0.0765) and enter the result on Schedule 
 2, column G. 
 
 ■ Column H. Tax Withheld from Form PW-1 – Enter the amount of pass-through entity withholding paid by 
 the  tax-option (S)  corporation on behalf of each shareholder, as  reported on Form PW-1. If this is an 
 amended return, report the tax previously assessed on the original return. 
 
 ■ Column  I.  Balance  Due  or  Overpayment  –  Compute  the  balance  due  or  overpayment  for  each 
 shareholder (column G - column H). 
 
 Schedule 1 Instructions 
 
 ■ Lines 1 through 9. Fill in the amounts as instructed on the form. If you have an overpayment on line 9, you 
 will not be able to carry over that overpayment to your 2024  Form 1CNS. Instead, the overpayment will 
 automatically be refunded to you. 
 
 ■ Line 4: Amended Return Only - Amount Previously Paid - If you have already filed a Form 1CNS for 
 the taxable year and are filing an amended Form 1CNS,  you must check the space provided at the top of 
 the form and include Schedule AR. 
 
 Fill in the amount of tax you paid with your original Form 1CNS plus any additional amounts paid after it was 
 filed. If you did not pay the full amount shown on your original Form 1CNS, fill in only the portion that you 
 actually paid. Also, include any additional tax that may have resulted if your original return was changed or 
 audited. This includes additional tax paid with a previously filed 2023 amended return and additional tax paid 
 as a result of a department adjustment to your return. Do not include payments of interest or penalties. 
 
 ■ Line 6: Amended Return Only - Amount Previously Refunded - Complete this line only if this is an 
 amended 2023 Form 1CNS. Fill in the refund from your original 2023 return.

                          Wisconsin 2023 Form 1CNS Instructions 
  
 If your refund was reduced because you owed any interest or penalties, fill in the amount of your refund 
 before the reduction for interest or penalty. If your 2023 return was adjusted by the department, fill in the 
 refund shown on the adjustment notice you received. 
 
 Instructions  for  Third  Party  Designee,  Signatures,  Payment,  and  Supplemental Schedules 
 
 ■ Third Party Designee – If you want to allow a tax preparer or tax preparation firm, or any other person 
 you  choose  to  discuss your 2023 tax return  with  the  Department of  Revenue,  check “Yes”  in  the  “Third 
 Party Designee” area of your return. Also, fill in the designee’s name, phone number, and any five digits the 
 designee chooses as their personal identification number (PIN). If you check “Yes,” you are authorizing the 
 department to discuss with the designee any questions that may arise during the processing of your return. 
 You are also authorizing the designee to: 
   • Give the department any information missing from your return, 
   • Call the department for information about the processing of your return or the status of your refund or 
     payment(s), and 
   • Respond to certain department notices about math errors, offsets, and return preparation. 
  
 You  are  not  authorizing  the  designee  to  receive  any  refund  check,  bind  you  to  anything  (including  any 
 additional  tax  liability),  or  otherwise  represent  you  before  the  department.  If  you  want  to  expand  the 
 designee’s  authorization,  you  must  submit  Form  A-222  (Power  of  Attorney).  The  authorization  will 
 automatically end no later than the due date (without regard to extensions) for filing your 2024 tax return. 
 
 Signatures. An officer of the corporation must sign and date Form 1CNS at the bottom of page 1. If the 
 return is prepared by someone other than an employee of the corporation, the individual who prepared the 
 return must also sign the form and furnish the preparing firm’s federal employer identification number. A 
 self-employed individual preparer  must enter “PTIN” and the preparer’s tax identification number in  the 
 space for the preparer’s federal employer ID number. 
 
 Payment. If you have an amount due on line 8, see the department's Make a Payment webpage. 
 
 Supplemental Schedules.  As described in the preceding instructions, you may be required to include one 
 or more supplemental schedules with your Form 1CNS, including: 
 
 • A copy of any application for an extension of time to file the return. 
 
 • If applicable, schedules to substantiate the shareholder’s share of Wisconsin tax-option (S) corporation 
   income (loss) reported in column D1. 
 
 Do not include federal Form 1120-S, Wisconsin Form 5S, Wisconsin Form PW-1, the federal Schedules K-1,
