Do you need a certificate of authority to operate in Pennsylvania?

The exempt activities are: defending, settling, mediating or arbitrating a case; internal affairs such as meetings of interest holders or governors; bank accounts; offices or trustees that handle the association's own securities; sales through independent contractors; taking orders that need acceptance outside the state; creating debts, mortgages or security interests; collecting debts and enforcing security, with holding and maintaining the property taken; one isolated deal that is not part of a pattern; interstate commerce; acquiring, owning, holding, leasing as lessee, conveying or transferring real or personal property without more; and good-faith disaster or emergency response work. The list is not exhaustive.

Pennsylvania chose to describe what is outside the rule instead of defining what is inside it. That makes the exempt list the main tool: if each thing your entity does in the state is on the list, you are outside the rule, and if something is not, the Department's description of regular local business is the next thing to compare it with.

A software company with no Pennsylvania office, whose online orders are accepted at its home base, sits on the exempt side. A contractor from Maryland that crews a six-month road job in Bedford County has more than an isolated deal. A manufacturer with a stocked Pennsylvania warehouse and local shipments is doing the sort of local business the Department describes. A holding company that owns shares in a Pennsylvania operating company is protected by the interest-holder rule, though the operating company is not. A nonprofit that runs a recurring program in the state is a local activity too.

The statute attaches a court-access consequence: an unregistered entity doing business here cannot bring an action in Pennsylvania until it registers. It keeps its contracts and its defenses. The fix is the ordinary $250 filing, which costs the same for every entity type and takes effect on filing or on a later date and hour you choose. Registering lifts the bar on starting a lawsuit from the filing date, not before, and an unregistered entity keeps answering any suit brought against it. A Pennsylvania business lawyer can tell you whether past activity crossed the line.
