What Is a Principal Place of Business?
The principal place of business of a company is the location where the company is primarily directed or controlled. In addition, it is the address where the company’s books and records are kept by the heads of the company.
The headquarters of a corporation, where its board of directors directs and manages the business, is often referred to as its “nerve center.” Even though the company’s assets and employees are located across the country, the nerve center is the location where the “brain” of the company is located.
This definition Principal Place of Business was established by the United States Supreme Court.
The highest US Court stated that the “nerve center” of a corporation is “the place where its officers direct and control the corporation’s affairs.”

Why Your Principal Place of Business Matters
Now that you know what the principal place of business is, you may be wondering why it matters. The truth is, this information helps determine a number of important factors regarding your company.
It Determines Which Courts Have Jurisdiction Over Your Company
The location of a company is one of the most important factors in determining which courts will hear a case involving two or more corporations. Basically, the plaintiff needs to file a lawsuit in the same state as the defendant.
If the case involves companies from different states, it is said to involve diversity of citizenship. If the value of the claim meets a certain threshold, the plaintiff will be able to file the lawsuit in a federal court instead of a state court.
In general, a corporation is a citizen of the state where it was incorporated and the state where its principal place of business is located. This is why the Court’s definition above is so relevant to the practice of law.
It May Influence Your Taxes
If you are a solo practitioner or a small-time business owner that operates from your home, you may be able to deduct certain expenses associated with your enterprise.
Can I Deduct My Residence From My Taxes?
Taxpayers can claim a deduction when they use a portion of their home where business is conducted. The deduction includes 100 percent of the interest on any mortgage or rent payments as well as the percentage of utilities that corresponds to the area used for business purposes.
There are a number of exceptions, though. For example, if the room is used exclusively and regularly for the meeting and treatment of patients, clients, or customers in the ordinary course of business.
According to the Tax Code, the exclusive use of a residence as an office is allowed in the following cases:
- exclusively and regularly as the principal place of business for the trade or business of the taxpayer,
- exclusively and regularly as a place for meeting and dealing with patients, clients, or customers in the ordinary course of business,
- as a separate structure not attached to the home used exclusively and regularly as an office in connection with the taxpayer’s trade or business
- regularly as a place for storing inventory or product samples in connection with a retail or wholesale business
- for rental use
- as a daycare facility.
Taxpayers that are solo practitioners and meet the requirements can deduct a proportionate share of expenditures related to their residence. Naturally, every individual has different circumstances, so it is best to consult a professional to find out what applies to your situation. There are many additional subtleties that are beyond the scope of this article.
How to Determine the Principal Place of Business
If you are still unsure what your principal place of business is, try to answer the following questions.
- Where are your company’s managers based? This is your nerve center.
- Where your company’s books and records are kept? This, most likely, is another vital part of your infrastructure.
- Where is the majority of your company’s operations conducted? For a retail company, for instance, it is the store.
- Can this address be referred to as a real place? The majority of states that require companies to report this information to the Secretary of State require a street address rather than a P.O. box.
- Is this address realistic? It should correspond to the actual location of the business.
If your company’s operations are conducted in more than one location, try to determine which one is the nerve center. It might not be the largest or the oldest one.
FAQs
Can My P.O. Box Be My Place of Business?
In most cases, it cannot. The reason is simple – the majority of jurisdictions require a street address. A P.O. Box is usually considered to be a mailing address.
Can I Provide My Home Address as My Place of Business?
Yes, if you operate your business from your home. Remember that the address you provide will typically become a matter of public record, so some people prefer to use a different address.
Can I Provide a Virtual Office Address as My Place of Business?
It depends on the jurisdictions you are dealing with and the particular case. If, for instance, your company’s management is based elsewhere, a virtual office address is unlikely to correspond to your principal place of business. Always make sure to determine the exact requirements you need to meet before providing any address.
If My Company Is Remote, What Is My Place of Business?
Where is your CEO based? Where does your company direct and control its operations? In the case of a remote company, the answer will pertain to the location of the chief executive officer.
Is It the Same State Where My Company Is Incorporated?
Not necessarily.
How Do I Change It?
It depends on the jurisdictions you are operating in. In most cases, either you or the company have to file an amended return with the Secretary of State or update the information when you file the next report. In most cases, there are fees involved, so make sure to always check the requirements in your particular jurisdiction.
