Business Tax Administrative Rules

Administrative rules related to the City of Portland Business License and Multnomah County Business Income Tax Laws


The City of Portland's Business License Law (PCC 7.02) and Multnomah County's Business Income Tax Law (MCC § 12) authorize the Revenue Division to adopt administrative rules relating to matters within the scope of the Business License and the Business Income Tax Laws (PCC 7.02.211 B / MCC § 12.210).  All Business Tax Administrative Rules (BTARs) have been adopted following the public hearing process established by the two laws (PCC 7.02.210 C and D / MCC §12.210 (C) and (D)).

Each Business Tax Administrative Rule has been given a number that identifies the code section it is interpreting and the year it was adopted.  For example, Business Tax Administrative Rule 100.93-1 would interpret or explain PCC 7.02.100 and MCC § 12.100.  It would further indicate that the rule was adopted in 1993 and was the first rule in the sequence of rules adopted that year for subsection 100.

The terms "City" or "County", as used in Business Tax Administrative Rule examples, shall include and may be substituted for the other jurisdiction, unless the rule only interprets a code section unique to one jurisdiction.
