How Much Does It Cost to Set Up an S Corp? The 2026 Complete Cost Guide

If you're wondering how much it costs to set up an S corp, the answer depends on several factors, including your state, whether you form an LLC or corporation first, and whether you handle the paperwork yourself or hire a professional.

For most small businesses, the cost to set up an S corp ranges from $150 to $5,000 or more. On the lower end, entrepreneurs who file their own paperwork may only pay state filing fees. On the higher end, hiring an attorney, accountant, and payroll provider can significantly increase your S corp first-year costs.

It's also important to understand that an S corporation is not a business entity; it's a tax status. Before you can elect S Corp status, you must first form a qualifying business entity (like a corporation or an LLC that will be taxed as an S Corp).

Beyond startup expenses, you'll also need to budget for S Corp annual costs, including payroll, tax preparation, state compliance fees, and bookkeeping. While these ongoing costs can add up, many business owners find that the potential S Corp tax savings outweigh the additional administrative responsibilities.

In this guide, we'll break down every expense associated with setting up and maintaining an S Corp, compare DIY and professional filing options, explain ongoing compliance costs, and help you determine whether electing S Corp status is the right financial decision for your business.

How much does it cost to set up an S corp?

The table below provides a general estimate of S Corp startup costs based on the method you choose.

These estimates typically include state formation fees, basic organizational documents, and professional assistance where applicable. However, they may not include recurring expenses such as payroll, bookkeeping, annual reports, or franchise taxes.

One important point to keep in mind is that the IRS does not charge a fee to file Form 2553, the document used to elect S Corporation tax status. The costs associated with becoming an S Corp come primarily from forming and maintaining your business rather than making the tax election itself.

What is an S corp?

Let’s back up for a minute: what exactly is an S corp? Many first-time business owners assume they can simply "register an S corp" with their state. In reality, that's not how the process works.

An S corporation is a tax classification recognized by the Internal Revenue Service. It allows eligible businesses to pass profits and losses through to their owners while potentially reducing self-employment taxes.

To become an S corp, you must first form one of the following business entities:

• A corporation

• An LLC that elects S corporation taxation

For many small business owners, forming an LLC taxed as an S corp offers the best balance of liability protection, operational flexibility, and tax advantages.

Once your business is legally formed, you'll submit IRS Form 2553 to the IRS to elect S corporation status. Assuming your business meets the eligibility requirements and files on time, the election generally becomes effective for the tax year requested.

How to elect S corp status

Understanding how to elect S corp status is essential because the process differs from forming a business.

The typical steps include:

1. Form an LLC or corporation with your state.

2. Obtain an Employer Identification Number (EIN) from the IRS.

3. Prepare your operating agreement or corporate bylaws.

4. Complete and submit IRS Form 2553.

5. Set up payroll if you'll be paying yourself as an owner-employee.

6. Continue meeting all federal and state compliance requirements.

While the election itself is free, mistakes on Form 2553 or missed filing deadlines can delay approval or require additional paperwork. Many business owners choose to work with a CPA or attorney to ensure everything is completed correctly.

What does it actually cost to set up an S corp?

The total cost to set up an S corp is made up of several individual expenses. Some are one-time startup costs, while others become recurring annual obligations.

Here's a breakdown of the most common expenses you'll encounter.

The exact amount you'll spend depends on your state, industry, and whether you choose a do-it-yourself approach or hire professionals to handle the process.

One-time startup costs explained

State formation fees

The first expense you'll encounter is your state's filing fee to legally form your business.

These fees vary widely across the country. Some states charge less than $100 to form an LLC, while others require several hundred dollars in filing fees. If you're forming a corporation instead of an LLC, the cost may differ.

Because these fees are established by each state, they're often the largest mandatory expense when calculating how much an S corp costs to establish.

Registered agent fees

Nearly every state requires businesses to maintain a registered agent who can receive legal and government correspondence.

If you're comfortable serving as your own registered agent and your state permits it, you may not incur an additional fee. Otherwise, professional registered agent services generally cost between $100 and $300 per year.

Although this expense is relatively modest, it's an important component of both S corp startup costs and S corp maintenance costs.

Business licenses and permits

Depending on your industry and location, your business may need one or more licenses before it can legally operate.

Examples include:

• Professional licenses

• Local business licenses

• Sales tax permits

• Health department permits

• Home occupation permits

The costs vary significantly, so it's important to research the requirements in your state and municipality when estimating your overall cost to set up an S corp.

Operating agreement or corporate bylaws

While not always required by state law, every business should have governing documents that explain ownership, management responsibilities, and operating procedures.

For LLCs, this is typically an operating agreement.

For corporations, it's usually corporate bylaws.

You can draft these documents yourself using reputable templates or work with an attorney if your ownership structure is more complex.

Employer identification number (EIN)

Every S corporation needs an Employer Identification Number (EIN) issued by the IRS. Fortunately, obtaining an EIN is completely free when you apply directly through the IRS.

Be cautious of third-party companies that charge unnecessary fees for this service. While they may provide additional filing assistance, the EIN itself does not cost anything.

IRS Form 2553

One of the most common misconceptions is that the IRS charges businesses to elect S corporation status, when in reality, IRS Form 2553 is free to file. As long as your business meets the eligibility requirements and files the form by the applicable deadline, you generally won't pay any federal filing fee to make the election.

If you miss the filing deadline, however, you may need to request late election relief, which can add complexity to the process (even though the IRS still doesn't charge a filing fee for the form itself).

Attorney or filing service costs

One of the biggest decisions you'll make is whether to handle the formation yourself or hire professional help. If your business has a single owner and a straightforward structure, filing the paperwork yourself may be sufficient.

Online formation services can simplify the process by preparing and submitting your state formation documents, obtaining your EIN, and offering registered agent services for an additional fee.

For businesses with multiple owners, investors, or more complex tax considerations, working with an attorney or experienced CPA may be worth the additional cost. Professional guidance can help prevent costly mistakes and ensure your business is structured correctly from the start.

S Corp Cost Calculator: Estimate your first-year costs

By now, you've probably realized there isn't a one-size-fits-all answer to how much an S corp costs. Your total investment depends on where you form your business, whether you hire professional help, and the ongoing services you'll need to stay compliant.

A simple way to estimate your S corp first-year costs is to list each expected expense before you begin the formation process.

Here's an example what that budget might look like for a single-member LLC that elects S Corp status and uses an online filing service.

Keep in mind that this is only an example. If you're comfortable handling the paperwork yourself, your costs could be lower. On the other hand, if you work with an attorney or have a more complex business structure, your first-year expenses may be considerably higher.

The goal isn't to arrive at an exact number before you get started. Instead, use this worksheet to build a realistic budget so you know what to expect.

Ongoing annual costs of an S corp

Getting your business set up is only part of the picture. To keep your S corp in good standing, you'll also need to plan for recurring expenses each year.

These S corp annual costs are often overlooked by new business owners, but they're just as important as the initial filing fees. Fortunately, once you understand what they are, they're much easier to budget for.

Some of the most common S corp maintenance costs include:

• Payroll administration

• Bookkeeping

• Tax preparation

• Annual reports

• State franchise taxes (where applicable)

• Registered agent renewals

• Business license renewals

Here's a general idea of what these recurring expenses might look like.

While these ongoing costs can seem like a lot at first glance, many business owners find they're well worth it because of the potential S corp tax savings. The key is understanding what you're paying for and making sure those expenses fit your business's financial goals.

S corp payroll costs

One of the biggest adjustments when you elect S corp status is payroll.

If you actively work in your business, the IRS generally expects you to pay yourself a reasonable salary before taking additional profits as shareholder distributions. This is one of the rules that helps distinguish legitimate wages from distributions that may receive different tax treatment.

Running payroll involves more than paying yourself every couple of weeks. You'll also need to:

• Withhold federal and state taxes

• Pay employer payroll taxes

• File payroll tax returns

• Issue a W-2 at year-end

• Keep accurate payroll records

For many small businesses, S corp payroll costs become the largest recurring expense after formation.

Here's what you can generally expect to pay.

If you're not familiar with payroll compliance, using a payroll service is often money well spent. Most providers automatically calculate payroll taxes, make tax deposits, and file the required reports on your behalf. That convenience can save you hours of work and potentially help you avoid costly mistakes.

CPA and tax preparation costs

While it's certainly possible to manage an S corp without an accountant, many business owners appreciate having a CPA in their corner.

An experienced CPA can help you:

• Prepare your business tax return

• File shareholder Schedule K-1s

• Stay compliant with IRS rules

• Determine an appropriate salary

• Plan ahead for taxes instead of scrambling at filing time

Because of these services, S corp CPA fees are a regular part of many businesses' annual budgets.

For a straightforward single-owner business, you might spend around $500 to $1,000 per year. Businesses with employees, multiple owners, or more complicated finances often spend more.

Rather than thinking of a CPA as another expense, many owners view the cost as an investment. Good tax planning can help you avoid penalties, uncover deductions, and make informed financial decisions throughout the year.

Bookkeeping and other annual expenses

Keeping accurate financial records is essential for any business, but it's especially important for an S corp.

Good bookkeeping helps you:

• Track income and expenses

• Prepare financial statements

• Run payroll accurately

• Make tax season much less stressful

Some owners handle bookkeeping themselves using accounting software, while others hire a professional bookkeeper. Either approach can work as long as your records stay organized and up to date.

You'll also want to budget for annual reports, business license renewals, registered agent services, and any state-specific taxes that apply to your business.

These expenses may seem relatively small on their own, but together they make up an important part of your ongoing S corp maintenance costs.

S corp costs by state

Where you form your business plays a major role in the total cost to set up an S corp.

Every state has its own filing fees, reporting requirements, and tax rules. As a result, two businesses that are otherwise identical can have very different costs simply because they're located in different states.

Here's a look at how some popular business-friendly states compare.

*Formation fees and ongoing requirements vary by entity type and may change over time.

**Texas has periodic reporting requirements that differ from many other states.

Although it's tempting to focus on the upfront filing fee, it's just as important to look at the long-term picture. A state with low startup costs may have higher annual compliance fees, while another state with a slightly higher formation fee could end up costing less over time.

If you're deciding where to form your business, consider both your S corp startup costs and your expected S corp annual costs.

Finally, remember that most businesses should form in the state where they actually operate. Forming in a different state to chase lower filing fees often creates additional registration requirements and extra compliance costs, which can outweigh any savings. Looking at the total cost of ownership—not just the initial filing fee—will help you make the best decision for your business.
