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 an 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 Maine 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.

Businesses that elect S corp status will need to hire payroll and accounting services.

How to Form a Maine 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 not starting a corporation with the S corp tax status because the S corp negates all of the benefits of a corporation.

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

Starting a Maine 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 Tailor Brands to guide you through this process.

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

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 Maine.

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

1. Follow the naming guidelines for a Maine LLC:

  • Your name must include the phrase “limited liability company” or “limited company” or one of their abbreviations (LLC, L.L.C., L.C., LC).
  • Your name cannot include obscene language.
  • Your name cannot promote abusive or unlawful activity.
  • Your name cannot falsely suggest an association with public institutions.
  • You must get approval from the Maine Bureau of Financial Institutions to include any of the following words in your name: savings, savings bank, bank, banker, banking, trust, trust company, trust and banking company, and credit union (or any plurals or variations).
  • Your name must be distinguishable from any existing business in the state. This includes Maine reserved names.
  • Low-profit LLC names must include "Low-profit Limited Liability Company, "L3C," or "13c."

You can also read the Maine state statutes about LLC naming guidelines for more information.

2. Is the name available in Maine? You can use the corporate name search on the Maine Department of the Secretary of State 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 Maine Registered Agent

You must elect a registered agent for Maine 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 Formation.

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.

Step 3: File the Maine LLC Certificate of Formation

The Maine Certificate of Formation is used to officially register an LLC.

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.

Keep Your Maine S Corp Compliant

Once you have your Maine S corp up and running, you need to ensure that you follow state and local laws to keep your business compliant and in good standing with the state of Maine. 

Maine S Corp Annual Report

Every Maine LLC must file an annual report with the Maine Secretary of State. While your business may be taxed as an S corporation, it is still technically an LLC and must comply with this requirement. 

Annual reports allow you to keep your business records and contact information up to date with the state, and even if your business does not change from one year to the next, you are still required to file an annual report by June 1st of each year. If you do not file an annual report, the state may take actions to dissolve your Maine business.

Check out our Maine Annual Report page for a step-by-step guide.

Maine 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 Maine 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.

Maine Income Taxes

Maine has a gradual income tax rate ranging from 5.80% to 7.15%. Similarly to federal income taxes, your Maine income tax rate will depend on your income bracket. While some states have income tax rates of 0%, other states have income tax rates upwards of 10%. Maine’s tax rate is on the higher end when compared to other states. 

Maine Sales and Use Tax

Maine has a state sales tax rate of 5.50%, and unlike other states, Maine does not have any local sales taxes. Therefore, all jurisdictions in Maine have a sales tax rate of 5.50%. You will need to register your business with the Maine Department of Administrative and Financial Services in order to pay sales and use taxes.

Additional State Taxes

Maine Revenue Services specifies a number of additional taxes your Maine business may need to register for and pay depending on your location, number of employees, and industry. 

Examples of such taxes Maine business owners may have to pay include:

  • Fuel tax
  • Insurance tax
  • Telecommunications tax
  • Alcohol tax
  • Property tax

Visit the Maine Revenue Services website for more information.

Maine Local Taxes

Many local jurisdictions have their own rules that may affect how your business operates. Whether you’re based in Portland, Lewiston, or a smaller city, we recommend familiarizing yourself with the regulations and laws of your local jurisdiction.

Start a Maine S Corp FAQ

What is an S corp?

An S corporation (S corp) is a tax designation for which an LLC or a corporation can apply.

Are taxes for LLCs and S corps the same?

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.

What is a reasonable salary for an S corp?

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.

What is a distribution?

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.

Can I still use my DBA name if I elect to be an S corp?

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