2021 MICHIGAN Business Tax Schedule of Business Activity
Protected Under Public Law 86-272
Issued under authority of Public Act 36 of 2007.

Taxpayer Name                                                      Federal Employer Identification Number (FEIN) or TR Number

Public Law (PL) 86-272, 15 USC 381-384, only affords protection from Business Income Tax when certain conditions are 
satisfied.  It does not apply to the Modified Gross Receipts Tax.
PL 86-272 restricts a state from imposing a tax on, or measured by, income derived within the state’s borders if the only business 
activity of the company within the state consists of the solicitation of orders for sale of tangible personal property. 
PL 86-272 does not prohibit Michigan from asserting that an out-of-state business has nexus. Implicit in the application of PL 86-272 
is that an out-of-state business has nexus.  PL 86-272 merely prohibits the imposition of tax based on net income generated from 
protected activities. PL 86-272 offers no protection from the Modified Gross Receipts Tax, therefore all gross receipts apportioned or 
allocated to Michigan are subject to the tax calculation.
PL 86-272 protection must be evaluated on a tax year by tax year basis. If at any time during a tax year an entity conducts activities that 
are not protected under PL 86-272, no income attributable to Michigan during any part of that tax year will be protected.

PART 1:  PROTECTED ACTIVITIES
The following activities conducted in Michigan by out-of-state businesses or on their behalf create nexus, subjecting the taxpayer to the 
Michigan Business Tax. However, PL 86-272 generally protects income generated from the sale of tangible personal property from the 
imposition of the income tax portion of the Michigan Business Tax in the following instances (check all that apply to your business in 
the current tax year):
 1. Soliciting orders for sales by advertising.

 2. Soliciting orders by an employee or representative of the entity so long as the individual does not, for the benefit of the entity, 
    maintain or use any office or other place of business in Michigan other than an “in-home” office.

 3. Carrying samples and promotional materials only for display or distribution without charge or other consideration.

 4. Furnishing and setting up display racks and advising customers on display of the company’s products without charge or other consideration.

 5. Providing automobiles to sales personnel for their use in conducting protected activities.

 6. Passing orders, inquiries and complaints on to the home office.

 7. Missionary sales activities; i.e., solicitation of indirect customers for the company’s goods. For example, a manufacturer’s 
    solicitation of retailers to buy the manufacturer’s goods from the manufacturer’s wholesale customers is protected if such 
    solicitation activities are otherwise protected.
 8. Coordinating shipment or delivery without payment or other consideration and providing information relating thereto either prior 
    or subsequent to the placement of an order.

 9. Checking of customers’ inventories, without a charge for re-order (but not for other purposes, such as quality control).

10. Recruiting, training or evaluating sales personnel, including occasionally using homes, hotels or similar places for meetings with sales personnel.

11. Mediating customer complaints when the purpose is solely for improving the relationship between the sales personnel and the 
    customer and facilitating requests for orders.

12. Owning, leasing, using or maintaining (i) personal property for use in the employee’s or representative’s “in-home” office, and/or 
    (ii) an automobile that is solely limited to the conducting of protected activities. For example, the use of personal property such 
    as a cellular telephone, facsimile machine, copier, personal computer and computer software will not subject the out-of-state 
    business to the Business Income Tax so long as the use of these items is limited to the carrying on of protected solicitation. 

                                                                                                                         Continue on Page 2.
