Tax 2.41 Tax 2.41 Separate accounting method.

Tax 2.41(1) (1) When the separate accounting method is used, separate records must be kept of sales, cost of sales and expenses for the Wisconsin business as distinct from the remainder of the business. Overhead items of income and expense must then be allocated to the business within and without Wisconsin upon a basis or combination of bases justified by the facts and conditions. For example: the ratio of Wisconsin sales to total sales usually represents a satisfactory basis for a merchandising business, while the ratio of direct cost of material and labor in Wisconsin to the total gives a more accurate result for a construction business.

Tax 2.41(1)(a) (a) Federal income taxes are based upon income and should, therefore, be allocated to Wisconsin business on the basis of income. Federal income taxes are deductible for income years through 1974 only on the cash basis, and the allocation to Wisconsin business for any year, therefore, must be based upon the ratio of income within Wisconsin to the total income of the year on which the federal income taxes are assessed, even though that ratio differs from the ratio of the year in which the taxes are actually paid. Federal income taxes are not deductible for income years 1975 and thereafter.

Tax 2.41(1)(b) (b) The relationship of the general overhead items to Wisconsin operations will determine whether the home office income and expense should be allocated to the Wisconsin business. Miscellaneous income, such as income from intangibles and income from tangible property used in the business, and such overhead items as officers’ salaries, office salaries, office rent and sundry office expenses should ordinarily be included in the allocation.

Tax 2.41(2) (2) Net rentals received from real estate held purely for investment purposes and not used in the operation of the business are not subject to allocation but are taxable in full if the property is located in Wisconsin. Gross rentals must be reduced by all expenses related to such investment property.

Tax 2.44 Tax 2.44 Permission to change basis of allocation. Except when income must be reported on the apportionment basis, permission to make a change either from separate accounting to apportionment, or vice versa shall be obtained in writing from the department upon written application setting forth in detail the reasons why the desired change will more clearly reflect the taxpayer’s Wisconsin income. Such application shall be mailed to the Wisconsin Department of Revenue, P.O. Box 8906, Madison, WI 53708-8906 before the end of the tax year for which the change is desired.

Tax 2.45 Tax 2.45 Apportionment in special cases. When the business of any person, other than an interstate professional sports club or “financial organization” or“public utility,” as defined in s. 71.25 (10), Stats., within Wisconsin is an integral part of a unitary business conducted within and without Wisconsin, but because of unusual or unique circumstances the portion of the income of the person derived from business transacted in Wisconsin cannot be ascertained with reasonable certainty by use of the apportionment formula provided in s. 71.25 (6), Stats., or by separate accounting in view of the unitary nature of the business, the department will substitute in the place of some or all of the statutory apportionment factors another factor or other factors as will reasonably apportion to Wisconsin the business income properly assignable to Wisconsin. In any case in which an apportionment of business income is made pursuant to this regulation the taxpayer, at the time of the assessment, will be apprised of the factors used in the formula adopted.
