Title IDAPA 35 - Tax Commission, State
Rule 35.01.01 - INCOME TAX ADMINISTRATIVE RULES
Section 35.01.01.546 - SALES FACTOR: SALES OTHER THAN SALES OF TANGIBLE PERSONAL PROPERTY IN THIS STATE - GENERAL RULES

a. Billing address. The location indicated in the books and records of the taxpayer as the primary mailing address relating to a customer's account as of the time of the transaction as kept in good faith in the normal course of business and not for tax avoidance purposes.

b. Business customer. A customer that is a business operating in any form, including a sole proprietorship. Sales to a non-profit organization, to a trust, to the U.S. Government, to a foreign, state or local government, or to an agency or instrumentality of that government are treated as sales to a business customer and must be assigned consistent with the rules for those sales.

c. Individual customer. A customer that is not a business customer.

d. Intangible property. Generally means property that is not physical or whose representation by physical means is merely incidental and includes, without limitation, copyrights; patents; trademarks; trade names; brand names; franchises; licenses; trade secrets; trade dress; information; know-how; methods; programs; procedures; systems; formulae; processes; technical data; designs; licenses; literary, musical, or artistic compositions; information; ideas; contract rights including broadcast rights; agreements not to compete; goodwill and going concern value; securities; and, except as otherwise provided in these rules, computer software.

e. Place of order. The physical location from which a customer places an order for a sale other than a sale of tangible personal property from a taxpayer, resulting in a contract with the taxpayer.

f. Population. The most recent population data maintained by the U.S. Census Bureau for the year in question as of the close of the taxable period.

g. Related Party.

h. State where a contract of sale is principally managed by the customer. The primary location at which an employee or other representative of a customer serves as the primary contact person for the taxpayer with respect to the day-to-day execution and performance of a contract entered into by the taxpayer with the customer.

a. A taxpayer shall apply the principles set forth in Rules 546 through 551 based on objective criteria and shall consider all sources of information reasonably available to the taxpayer at the time of its tax filing including the taxpayer's books and records kept in the normal course of the taxpayer's business. A taxpayer shall determine its method of assigning receipts in good faith and apply it consistently with respect to similar transactions and year to year. A taxpayer shall retain contemporaneous records that explain the determination and application of its method of assigning its receipts, including its underlying assumptions, and shall provide those records to the Tax Commission upon request.

b. Rules 546 through 551 provide various assignment rules that apply sequentially in a hierarchy. For each sale to which a hierarchical rule applies, a taxpayer must make a reasonable effort to apply the primary rule applicable to the sale before seeking to apply the next rule in the hierarchy (and must continue to do so with each succeeding rule in the hierarchy, where applicable). For example, in some cases, the applicable rule first requires a taxpayer to determine the state or states of assignment, and if the taxpayer cannot do so, the rule requires the taxpayer to reasonably approximate the state or states. In these cases, the taxpayer must attempt to determine the state or states of assignment (i.e., apply the primary rule in the hierarchy) in good faith and with reasonable effort before it may reasonably approximate the state or states.

c. A taxpayer's method of assigning its receipts, including the use of a method of approximation, where applicable, must reflect an attempt to obtain the most accurate assignment of receipts consistent with the standards set forth in Rules 546 through 551, rather than an attempt to lower the taxpayer's tax liability. A method of assignment that is reasonable for one taxpayer may not necessarily be reasonable for another taxpayer, depending upon the applicable facts.

a. In General. In general, Rules 546 through 551 establish uniform provisions for determining whether and to what extent the market for a sale other than the sale of tangible personal property is in this state. These rules also set forth provisions of reasonable approximation, which apply if the state or states of assignment cannot be determined. In some instances, the reasonable approximation must be made in accordance with specific provisions of approximation prescribed in these rules. In other cases, the applicable provision in these rules permits a taxpayer to reasonably approximate the state or states of assignment, using a method that reflects an effort to approximate the results that would be obtained under the applicable provisions or standards set forth in these rules.

b. Approximation Based Upon Known Sales. In an instance where, applying the applicable provisions set forth in Rule 548 (Sale of a Service), a taxpayer can ascertain the state or states of assignment of a substantial portion of its receipts from sales of substantially similar services ("assigned receipts"), but not all of those sales, and the taxpayer reasonably believes, based on all available information, that the geographic distribution of some or all of the remainder of those sales generally tracks that of the assigned receipts, it shall include receipts from those sales which it believes tracks the geographic distribution of the assigned receipts in its sales factor in the same proportion as its assigned receipts. This provision also applies in the context of licenses and sales of intangible property where the substance of the transaction resembles a sale of goods or services. See Rule 549.05 and 550.01.c.

c. Related-Party Transactions - Information Imputed from Customer to Taxpayer. Where a taxpayer has receipts subject to these rules from transactions with a related-party customer, information that the customer has that is relevant to the sourcing of receipts from these transactions is imputed to the taxpayer, unless the taxpayer shows that imputing such knowledge is unreasonable.
