                                              Business Income Worksheet 
Complete the appropriate parts below, based on the person’s organization type. Part 1 is for an Individual or Fiduciary; Part 2 is for a C Corporation (or a  
person filing federal returns as a C Corporation); and Part 3 is for a Partnership or S Corporation (or a person filing a federal return as a Partnership or an S  
Corporation). This worksheet will calculate business income as defined by law in most circumstances. Taxpayers and tax professionals are expected to be  
familiar with uncommon situations within their experience, which produce business income not identified by specific lines on this worksheet, and report that  
amount on the most appropriate line. Include an attachment explaining that line. The Michigan Department of Treasury may adjust the figure resulting from  
this worksheet to account properly for such uncommon situations. Complete and attach this worksheet to your return. Unitary Business Groups (UBG) must  
complete and attach a worksheet for each member.

(a) U.S. Forms 1040D and 4797: Report only gains or losses from assets used in a business activity.  Do not include personal gains and losses. 
 
(b) For the computation of business income for Michigan Business Tax (MBT) purposes, persons who claimed a federal special depreciation deduction 
    under IRC § 168(k) on property first placed in service in 2008 or later must calculate the net bonus depreciation adjustment on those assets as follows: 
    net bonus depreciation adjustment in tax year equals the total federal depreciation claimed in tax year less the total amount of depreciation that would 
    be claimed in the federal return in the tax year if the person had elected not to utilize the bonus depreciation allowance at IRC § 168(k). A person may 
    not elect IRC § 179 expensing of an asset for MBT purposes if it did not elect to use IRC § 179 for that asset federally. 
(c) For the computation of business income for MBT      purposes, persons who claimed a federal special depreciation deduction under IRC § 168(k) on                                                                 
 property first placed in service in 2008 or later and subsequently disposed of that property in the current tax year must calculate the gain/loss adjustment  
 on the sale of those assets as follows: gain/loss adjustment in tax year equals the total amount of federal depreciation that would be claimed in the  
 federal return over the years (starting the year the asset was placed in service and ending on the current tax year) if the person had elected not to utilize  
 the bonus depreciation allowance at IRC § 168(k) on the property being disposed LESS the total federal depreciation claimed over the years (starting  
 the year asset was placed in service and ending on the current tax year). A person   may  not  elect  IRC      179§  expensing      anof                                                 asset  for  MBT  purposes      if
 it did not elect to use IRC § 179 for that asset federally. 
(d) Generally, IRC 199 was repealed effective for tax years beginning after December 31, 2017. Therefore, most taxpayers will leave this line blank.                                                                 
   However, the federal deduction can still be taken in limited circumstances or it’s possible that a member of a UBG return includes in this return its tax year  
   beginning before January 1, 2018. In any case, to the extent a deduction was taken in this tax year’s federal taxable income, report that deduction here.
