Upper Merion Township (King of Prussia) Business Privilege Tax and Business Registration

If your business operates in King of Prussia, you need to find out whether your location sits in Upper Merion Township. The township collects its own local business taxes and charges an annual business license fee. Pennsylvania has no general business license that every business must hold, and it does not issue county business licenses either. That makes the local steps in this guide the ones new owners most often miss.

This article is informational, not legal or tax advice. Township tax rules and administrative details can change, so confirm each point with the agency named before you rely on it. If your situation involves multiple owners, employees, out-of-state sales, or a complex entity structure, talk with a Pennsylvania attorney or certified public accountant (CPA).

What Upper Merion Township Taxes

Upper Merion uses two gross receipts taxes. Which one applies depends on what you sell.

• Business Privilege Tax (BPT): applies to service businesses such as insurance agents and brokers, doctors, lawyers, consultants, auto mechanics, and similar businesses.
• Mercantile Tax: applies to businesses selling merchandise to the public.

Both taxes are set at 1.5 mills, which is $1.50 for every $1,000 of gross receipts. The BPT is a grandfathered levy that collected more than $10 million in 2018, so it remains a significant source of township revenue. Every business also pays an annual $25 business license fee, regardless of which gross receipts tax applies.

For example, a consulting firm with $400,000 in gross receipts would calculate its BPT at 1.5 mills: $400,000 divided by 1,000 is 400, and 400 times $1.50 is $600. The $25 license fee would be separate. This is an illustration only. Confirm with Tri-State whether any exclusions or exemptions apply before you estimate your own bill.

Item	Who pays	Amount	Timing
Business Privilege Tax	Service businesses	1.5 mills ($1.50 per $1,000 of gross receipts)	Return due April 15 each year
Mercantile Tax	Businesses selling merchandise to the public	1.5 mills ($1.50 per $1,000 of gross receipts)	Return due April 15 each year
Annual business license fee	Every business	$25	Confirm payment timing with Tri-State

Materials You Need Before You Start

Gather these items before you contact the township or file anything. Having them ready prevents the stop-and-start delays that slow most registrations.

• A Pennsylvania street address for your business location, and confirmation that it falls within Upper Merion Township.
• Your formation or name documents: a Department of State filing confirmation for your LLC or corporation, or a fictitious name registration if you operate under a trade name.
• A registered office in Pennsylvania with a street and number, or a Commercial Registered Office Provider (CROP) contract if you have no Pennsylvania address.
• A federal Employer Identification Number (EIN) from the IRS, if your entity or payroll requires one.
• A sales tax account set up through myPATH if you sell merchandise. The state sales tax rate is 6%.
• A written description of your activities, so you can explain to Tri-State whether you are a service business, a merchandise seller, or both.
• Monthly gross receipts records. Confirm with Tri-State which reporting period the township requires.
• A Montgomery County Office of Public Health food license application, if you prepare or serve food.
• The Tri-State Financial Group phone number: 610-270-9520.

Step-by-Step: Registering Your Business in Upper Merion

Step 1: Confirm your location is in Upper Merion Township

King of Prussia is a mailing name, not a municipality. Many King of Prussia addresses are in Upper Merion Township, but some sit in neighboring municipalities with their own tax rules. Before you sign a lease or register, ask the township or Tri-State which taxing authority covers your parcel. A King of Prussia mailing address alone does not answer that question.

Step 2: Form your entity or register your trade name

To form an LLC, file the Certificate of Organization (Form DSCB:15-8821) with a Docketing Statement (DSCB:15-134A) through the Department of State's Business Filing Services at file.dos.pa.gov. The filing fee is $125, and the Bureau asks filers to allow about 15 business days for processing. Your LLC name must include the term Company, Limited, or Limited Liability Company, or an accepted abbreviation of one of those terms. It may not contain words implying a business corporation, such as Corporation or Incorporated. Pennsylvania LLCs have no publication requirement.

Corporations file Articles of Incorporation for the same $125 filing fee, along with a Docketing Statement. Corporations also must advertise notice of the intent to file or of the filing in two newspapers of general circulation, one preferably a legal journal, and keep proof of publication in the corporate minutes.

If you operate under a name other than your legal name, register a fictitious name for $70 using Form DSCB:54-311. The registration is filed with the Department of State statewide, not with the county.

Step 3: Set up your Pennsylvania registered office

Pennsylvania does not use registered agents. Every filing association must list a registered office in Pennsylvania with a street and number. A post office box alone is not accepted. If you have no Pennsylvania physical or mailing address, you may contract with a CROP under 15 Pa.C.S. section 109 and list the provider's name and county of venue in place of an address. Listing a CROP without a contract can carry civil and criminal penalties. A CROP also cannot be used where a principal place of business is required, such as a fictitious name registration.

Step 4: Register your state tax accounts through myPATH

Pennsylvania does not issue a general business license, but you still need state tax accounts where they apply. If you sell merchandise, register for a Sales, Use and Hotel Occupancy Tax License through myPATH, starting at pa.gov/services/revenue/register-my-business-for-taxes. The Pennsylvania Department of Revenue's main page is pa.gov/agencies/revenue. The PA-100 paper registration was retired in 2022, so any guide that tells you to file a PA-100 is out of date.

If your LLC is not taxed as a corporation, its income passes through to the owners and is taxed at the flat 3.07% Pennsylvania personal income tax rate. Confirm with a CPA how your entity's federal classification affects your state filings.

Step 5: Register locally with Upper Merion before you open

King of Prussia retail and office businesses register before they begin operating, so do not wait for your first tax bill. Call Tri-State Financial Group at 610-270-9520. Tri-State is the township's tax administrator for the BPT, the Mercantile Tax, the Local Services Tax, and the Amusement Tax. Ask these questions:

• Does my business fall under the BPT, the Mercantile Tax, or both?
• Do I need to register with the township, and if so, which form and fee apply?
• Which gross receipts period does my first return cover?
• Are there any exclusions or exemptions I should document now?
• When and how is the $25 annual business license fee paid?

Ask for the answers in writing and keep them in your business file.

Step 6: Track gross receipts from your first sale

Both gross receipts taxes are calculated on gross receipts, not net profit, so you need a clean record of every dollar that comes in. Run business receipts through one dedicated account, export a monthly report, and tag each sale as service or merchandise if you do both. Mixed businesses should confirm with Tri-State how each revenue stream is taxed.

Step 7: Pay the license fee and file the annual return by April 15

Returns are due April 15 each year. Mark that date on your calendar. Confirm with Tri-State the reporting year the return covers, whether online filing is available, and whether any extension is possible. Do not assume an extension exists. Because the tax is based on gross receipts, it can be owed even in a year when the business shows little or no profit, so set cash aside for it throughout the year.

Step 8: Check the other local taxes that may apply

• Earned income tax (EIT): Berkheimer is the Montgomery County Act 32 collector. If you have employees, confirm your withholding duties with Berkheimer.
• Local Services and Amusement taxes: Tri-State administers both. Ask whether either applies to your activities.
• Food businesses: Obtain a Montgomery County Office of Public Health food license before you open. Confirm the application process directly with the county office.

Common Mistakes to Avoid

• Assuming a King of Prussia mailing address settles your tax jurisdiction. Verify the parcel location first.
• Looking for a state or county business license. Pennsylvania has no general business license, and there are no county business licenses. Your township obligations are the BPT or Mercantile Tax and the $25 fee.
• Registering a fictitious name with the county. The registration is filed with the Department of State.
• Listing a post office box as your registered office. Pennsylvania requires a street address or a valid CROP arrangement.
• Using a PA-100 form. It was retired in 2022. Register through myPATH.
• Confusing the BPT with the Mercantile Tax. A return filed under the wrong category can leave an underpayment you then have to correct. Ask Tri-State to classify your activities in writing.
• Waiting until April. Start a monthly receipts log from the first day of sales.
• Counting only the $25 fee. The gross receipts taxes are the larger obligation for most businesses.
• Looking for an LLC publication requirement. Pennsylvania LLCs have none. Corporations do have one.

Tips for a Smoother Registration

• Start the township conversation when you sign your lease, not on opening day.
• Save every filing confirmation, including the Department of State receipt and your myPATH account details.
• Reconcile your receipts a few weeks before April 15 so the return is not built from memory.
• Ask a CPA to review how gross receipts are computed for your business model before your first return.
• If you need help with planning or recordkeeping, the Pennsylvania Small Business Development Centers offer free or low-cost advising.

What to Expect

Many owners find that the local setup takes the most time in the first year. Once the receipts log and filing calendar are in place, the annual routine usually becomes simpler. Your results will depend on your business type, your location, and the township's current procedures, so treat the timing here as a starting point. The Department of State's estimate of about 15 business days for processing can help you plan your opening date. Expedited service is available for an added fee, online or in person only, so check the current options at file.dos.pa.gov.
