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 an Arizona 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 an Arizona 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 Arizona

Starting an Arizona 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 six 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 Articles of Organization

Step 4: Complete Publication Requirement

Step 5: Create an Operating Agreement

Step 6: 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 Arizona.

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

1. Follow the naming guidelines for an Arizona LLC:

  • Your name must contain the following words or abbreviations: limited liability company, limited company, L.L.C., L.C., LLC, or LC.
  • Your name cannot contain the words "association," "corporation," "incorporated," or an abbreviation of those words.
  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
  • Your name must be distinguishable from any existing business in your state. You can find more information about what makes a business name distinguishable on Arizona’s state legislature website.

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

2. Is the name available in Arizona? You can use the eCorp business entity search on the Arizona Corporation Commission 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 Arizona Registered Agent

You must elect a statutory agent, also known as a registered agent, for your Arizona 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 Articles 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.

Arizona Registered Agent Consent to Appointment

Statutory agents in Arizona must consent to their appointment in written or electronic form.

The statement of consent should include:

  • The name of your LLC
  • The name of the person designated as statutory agent
  • An express statement that the person designated consents to serve as the LLC’s registered agent
  • The signature of the statutory agent
  • The date of execution

Step 6: 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 Arizona S Corp Compliant

Creating a business is a big undertaking, but, once you establish your company and elect S corp status, you also need to keep your business compliant with state and federal laws. All Arizona S corps must file an Arizona S Corporation Income Tax Return with the state. Some businesses also will need to pay an Arizona transaction privilege tax. 

Arizona S Corp Annual Report

Unlike in most states, Arizona LLCs that elect the S corp tax designation don’t have to file an annual report. However, S corps in this state must still pay all applicable taxes. 

Arizona 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 Arizona S corp owners can expect to pay the following 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.

Arizona Income Taxes - Form 120S

All LLCs taxed as S corps must file Form 120S (Arizona S Corporation Income Tax Return) with the Arizona Department of Revenue. You must file this form each year to keep your business in good standing. If your S corp runs on a calendar year, the due date for this will be March 15.

In addition to filing Form 120S, you’ll need to pay the income tax itself. The current state income tax rate in Arizona is 4.9%. Because state income taxes can range from 0% to 10%, Arizona’s 4.9% rate falls near the middle. If your income tax liability exceeds $1,000, you’ll need to pay on a quarterly basis. You can make your tax payments on Arizona’s AZTaxes website. 

Arizona Sales and Use Tax

Arizona calls its sales and use tax a transaction privilege tax (TPT). If the state requires your business to pay the TPT, then your business also must apply for a TPT license through the Arizona Department of Revenue.

Businesses that must pay the TPT and register for a TPT license include: 

  • Retail Sales
  • Restaurants/Bars
  • Hotels/Motels (Transient Lodging)
  • Commercial Leasing Companies
  • Amusements
  • Personal Property Rentals
  • Contracting
  • Severance (Metal Mining)
  • Transportation Companies
  • Non-metal Mining
  • Job Printing
  • Publishing
  • Utilities
  • Telecommunications
  • Private (Rail) Car

For more information, check out the Arizona Department of Revenue website.

Arizona Local Taxes

Whether your business is in Phoenix, Tucson, or one of the state’s smaller cities, each local municipality may have its own taxes that apply to your business. Check with your local government to make sure your business complies with local laws.

Start an Arizona 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.

Arizona is one of the few states that don’t require you to file an annual report after you form your S corp. This reduces the annual paperwork burden on you and your business. Only corporations have to file an annual report in Arizona.

While each state offers many different benefits, no single state is better than another in terms of forming an S corp. Arizona has a low tax burden and a supportive business climate, making it a great place for small business owners to form an S corp.
