S Corporation Restrictions

S corps have several restrictions, such as being limited to one class of stock and 100 shareholders. Read our What Is an S Corporation guide for full details.

Are S Corp Tax Advantages Right for You?

An S corporation is a tax designation that can be elected by a limited liability company (LLC) or corporation. With an S corp, business owners are considered employees of the company and must receive a reasonable salary. Since all S corps technically have employees, the s corp must run payroll. 

In order to benefit from a Massachusetts S corp tax designation, your business needs to make enough money to offset payroll expenses. Furthermore, S corps are beneficial for business owners who take large distributions in addition to their salary.

To learn more about the tax advantages of an S corp, read our LLC vs. S corp guide and take a look at our S corp tax calculator.

How to Form a Massachusetts S Corp

There are two main ways to start an S corp:

  • By forming an LLC and electing S corp tax status from the IRS when you request your employee identification number (EIN)
  • By forming a corporation and electing S corp status from the IRS

We recommend forming an LLC because it’s simpler and more cost-effective.

Steps for Forming an LLC and Electing S Corp Status in Massachusetts

Starting a Massachusetts LLC and electing S corp tax status is easy. You can use our guides to start an LLC with the S corp status yourself, or you can hire a service provider like Northwest to guide you through this process.

There are five basic steps to start an LLC and elect S corp status:

Step 1: Name Your LLC

Step 2: Choose a Registered Agent

Step 3: File the Certificate of Organization

Step 4: Create an Operating Agreement

Step 5: Get an EIN and File Form 2553 to Elect S Corp Tax Status

Step 1: Name Your LLC

Choosing a company name is the first and most important step in starting your LLC in Massachusetts.

Be sure to choose a name that complies with Massachusetts naming requirements and is easily searchable by potential clients.

1. Follow the naming guidelines for a Massachusetts LLC:

  • Your name must include the phrase “limited liability company” or “limited company” or one of their abbreviations (LLC, L.L.C., LC, or L.C.).

  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).

  • Restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual to be part of your LLC.

  • Your name cannot be the same as or deceptively similar to any existing business in Massachusetts. This includes reserved names.

You can also read the Massachusetts state statute about LLC naming guidelines for more information.

2. Is the name available in Massachusetts? You can use the business entity search and the name reservation search on the Massachusetts Secretary of the Commonwealth website to see if your desired LLC name is available.

3. Is the URL available? We recommend checking to see if your business name is available as a web domain. Even if you don't plan to create a business website today, you may want to buy the URL in order to prevent others from acquiring it.

Step 2: Choose Your Massachusetts Registered Agent

You must elect a resident agent, also known as a registered agent, for your Massachusetts LLC.

An LLC registered agent will accept legal documents and tax notices on your LLC's behalf. You will list your registered agent when you file your LLC's Certificate of Organization.

Many business owners choose to hire a registered agent service. Many of these services will form your LLC for a small fee and include the first year of registered agent services for free.

Massachusetts Registered Agent Consent to Appointment

Registered agents in Massachusetts must consent to their appointment. They can do this by signing the LLC’s Certificate of Organization or a separate statement that is then attached to the Certificate of Organization.

If filing Certificate of Organization online rather than a hard copy, you will have to sign electronically, stating that the registered agent has consented to the appointment.

Step 3: File the Massachusetts LLC Certificate of Organization

The Massachusetts Certificate of Organization is used to officially register an LLC.

Our operating agreement tool is a free resource for business owners.

Step 5: Get an EIN and Complete Form 2553 on the IRS Website

An EIN is a number that is used by the US Internal Revenue Service (IRS) to identify and tax businesses. It is essentially a Social Security number for a business.

EINs are free when you apply directly with the IRS.

During the online EIN application, the IRS will provide a link to Form 2553, the Election By a Small Business form.

Keep Your Massachusetts S Corp Compliant

After forming your Massachusetts business and electing S corp status, you’ll want to ensure you understand state and local laws in order to keep it in good standing with the state. 

Massachusetts S Corp Annual Report

Every year, your Massachuesetts S corp must file an annual report and cover sheet with the Massachusetts Secretary of the Commonwealth. Because your business is an LLC taxed as an S corp, you must file the LLC annual report. 

This annual report provides the state with important information, such as your business’s name, address, registered agent details, and members’ contact details. Even if your business’s information remains the same from year to year, you must still file an annual report each year. The filing deadline is your business’s anniversary date, which is the day you officially registered your LLC — not the day you elected S corp status.

For more information, see our step-by-step Massachusetts Annual Report guide.

Massachusetts S Corp Taxes

S corporations benefit from pass-through taxation, meaning the business’s profits pass-through to S corp owners’ individual tax returns. S corp owners make money from their reasonable salary and distributions, and Massachusetts S corp owners will need to pay various taxes.

Federal Self-Employment Taxes

Self-employment taxes cover social security and medicare. The self-employment tax rate is 15.3%, and money you take as salary will be subjected to the self-employment tax. However, distributions are not subjected to this tax.

Federal Income Taxes

Your federal income taxes will depend on your tax bracket, and the cutoffs for individual tax brackets as well as the percent owed will change each year. Both your salary and distributions are subjected to federal income tax.

Massachusetts Income Taxes

Massachusetts has a flat 5% income tax rate. This means all individuals in the state pay a 5% tax on their income regardless of their income bracket. 

Some states have no income tax while others impose income tax rates of more than 10%. That makes Massachusetts’s 5% income tax rate fairly standard when compared to other states.

Register for Massachusetts Taxes

Because LLCs that elect S corp status are “pass-through” entities, you won’t have to pay corporate business taxes. However, you’ll still need to pay local and state business taxes like sales tax and any additional miscellaneous taxes. 

Before your business starts operating, you must register it with the Massachusetts Department of Revenue so you can fulfill your business tax obligations.

Massachusetts Sales and Use Tax

Massachusetts has a statewide sales tax of 6.25%. While some states allow local jurisdictions to levy an additional sales tax on top of the statewide sales tax, Massachusetts local jurisdictions don’t do so. That means you’ll pay a 6.25% sales tax rate no matter where your business operates in Massachusetts.

Additional State Taxes

The Massachusetts Department of Revenue provides details on numerous other taxes your business may need to pay, depending on its industry, location, and number of employees. Some examples of these additional taxes include:

  • Alcoholic Beverage Excise Tax
  • Marijuana Retail Taxes
  • Meals Tax
  • Out-of-State Contractors Tax
  • Room Occupancy Excise Tax
  • Telecommunications Tax

Visit the Massachusetts Department of Revenue website for more information.

Massachusetts Local Taxes

The local laws and regulations in Boston may differ drastically from those in Worcester. Regardless of your business’s location within the state of Massachusetts, you should familiarize yourself with your local jurisdiction’s laws and regulations. This’ll help you keep your business in good standing and ensure you understand any laws that’ll impact how you do business.

Start a Massachusetts S Corp FAQ

An S corporation (S corp) is a tax designation that an LLC or a corporation can elect.

No. The default taxes for an LLC and taxes for an S corp are not the same.

With an S corp, owners pay personal income tax and self-employment tax on a predetermined salary. They may then withdraw any remaining profits from the business as a “distribution,” which isn’t subject to self-employment tax.

With an LLC, all company profits pass through to the owners’ personal tax returns, and then the owners must pay personal income tax and self-employment tax on the entire amount.

S corp owners are required to earn a “reasonable” salary, which basically means a fair market rate based on the individual’s qualifications as well as their duties and responsibilities at the company. The purpose of this requirement is to prevent S corp owners from paying themselves an artificially low salary in order to pay less self-employment tax.

A distribution is a dividend that a shareholder/owner can take from the business profits that remain after a company pays all of its employee salaries. Shareholders must pay personal income tax on distributions, but distributions aren’t subject to self-employment tax.

LLCs and corporations that operate under a “doing business as” (DBA) name can choose the S corp election.

Massachusetts has a healthy economy built across several sectors, including education, technology, and healthcare. As long as your business meets the IRS’s requirements for an S corp, you can form an S corp in just about any industry.

If you already formed your business as an LLC, it's not too late to update its tax status. The process for forming an S corp is almost identical to forming an LLC. You’ll just need to file Form 2553 with the IRS.
