S Corp or LLC for a Small North Carolina Business: When the Switch Starts Paying Off

· RKube Services

When an S corp election actually saves a North Carolina LLC owner money: reasonable salary, payroll costs, the NC franchise tax and a worked ,000 example.

Sooner or later, someone tells you to "become an S corp." Maybe it's a friend who owns a landscaping company, a podcast host, or a stranger in a Facebook group. The pitch is always the same: you'll save thousands on taxes.

Sometimes that's true. Sometimes the switch costs more than it saves, adds a payroll you didn't want, and creates a new set of deadlines you can miss. The answer depends on your profit, how steady it is, and how much paperwork you're willing to keep up with.

This article explains what the choice actually is, how the savings work, what it costs to run an S corp in North Carolina, and the questions to ask before you file anything. It's written for owners of small service businesses, contractors, consultants and agencies, but most of it applies to any small company.

First, clear up the biggest confusion

An LLC and an S corp are not two competing kinds of business. They answer different questions.

An LLC is a legal structure. You form it with the North Carolina Secretary of State. It separates your business from you personally, which matters for liability, contracts and bank accounts.

An S corp is a tax status. It's an election you make with the IRS on Form 2553. It changes how the business's profit is taxed, not what kind of legal entity it is.

That means an LLC can choose to be taxed as an S corp. Plenty of small businesses are exactly that: a North Carolina LLC on paper, taxed as an S corp for federal purposes. You don't have to dissolve your LLC or form a corporation to make the election.

So the real question is not "LLC or S corp?" It's "Should my LLC keep its default tax treatment, or elect S corp status?"

How a regular single-member LLC is taxed

By default, a single-member LLC is a "disregarded entity." The IRS treats it as if the business doesn't exist separately from you. Your profit goes on Schedule C of your personal return.

On that profit, you pay two things:

  • Regular income tax, federal and North Carolina
  • Self-employment tax, which covers Social Security and Medicare

Self-employment tax is the part that surprises people. It's 15.3 percent on most of your net earnings, on top of income tax. An employee splits that cost with their employer. When you're self-employed, you pay both halves.

Multi-member LLCs work similarly. By default they're taxed as partnerships, and each member pays self-employment tax on their share of active business income.

What changes when you elect S corp status

Once your LLC is taxed as an S corp, you become an employee of your own business. The company runs payroll and pays you a salary. Social Security and Medicare taxes apply to that salary, just like any other job.

Profit left over after your salary can be paid to you as a distribution. Distributions are still subject to income tax, but they are not subject to Social Security and Medicare taxes.

That's the whole source of the savings. You stop paying 15.3 percent on every dollar of profit and only pay payroll taxes on the salary portion.

Here's a simple illustration with round numbers. Say your business earns $120,000 in profit after expenses. As a default LLC, nearly all of that is exposed to self-employment tax. As an S corp, suppose you pay yourself a salary of $65,000 and take the remaining profit as distributions. Payroll taxes apply to the $65,000, not the full $120,000. The difference in payroll tax on that $55,000 gap can be meaningful.

That's an illustration, not a promise. Your actual result depends on your salary, your state taxes, other deductions and how the numbers interact with the rest of your return.

The catch: "reasonable salary"

If the savings come from paying yourself less in salary, why not pay yourself $10,000 and take everything else as a distribution?

Because the IRS expects S corp owners who work in the business to pay themselves a reasonable salary for the work they do. That generally means something close to what you'd have to pay someone else to do your job. A consultant billing at senior rates can't reasonably pay themselves like an entry-level assistant.

There's no single formula. People usually look at what similar roles pay in your area and industry, how many hours you work, your experience and what the business can afford. Keep notes on how you arrived at the number. If the IRS ever asks, a documented, sensible approach is much better than a number that was picked to minimize tax.

Setting salary too low is one of the most common problems with S corps. It can lead to back payroll taxes, penalties and interest. Setting it too high wipes out the savings. This is where a tax professional earns their fee.

What it actually costs to run an S corp

The savings are only half the math. Running an S corp adds real costs and real work:

  • Payroll. You need a payroll system, quarterly federal payroll filings, year-end W-2s and state withholding filings. If you've never run payroll, this is new.
  • North Carolina unemployment insurance. Once you're on payroll, you may need to register with the NC Division of Employment Security and file quarterly reports, depending on your situation.
  • A separate business tax return. An S corp files Form 1120-S with the IRS, generally due March 15 for calendar-year businesses, plus a North Carolina S corporation return. Your personal return gets a Schedule K-1 from the business.
  • North Carolina franchise tax. S corps in North Carolina are generally subject to the state franchise tax, which an LLC taxed as a sole proprietorship doesn't pay.
  • Cleaner books. Distributions, owner reimbursements and payroll all need to be recorded correctly. Messy books make S corp returns slow and expensive.
  • Professional fees. Most owners pay more for tax prep and payroll once they elect S corp status.

Add those up before you compare them to the payroll tax savings. If the savings are small, the extra cost and hassle can eat most of them.

When the switch usually starts to make sense

There's no magic profit number, and anyone who quotes one without looking at your situation is guessing. Still, some patterns are common.

The election tends to be worth a closer look when:

  • Your business has steady profit, not just steady revenue, and you expect it to continue
  • Profit is comfortably above what a reasonable salary for your role would be
  • You're already keeping clean monthly books, or you're willing to start
  • You're comfortable with payroll, or you'll pay someone to handle it

It usually doesn't make sense yet when:

  • The business is new and profit is unpredictable
  • Most of your profit would need to be paid as salary anyway
  • You're likely to have a loss year soon
  • You're planning to bring in investors in a way that S corp rules don't allow

That last point matters for growing companies. S corps have ownership limits. They generally can have only one class of stock and a limited number of shareholders, and most shareholders must be US citizens or residents. Founders raising venture money usually end up with a C corporation instead.

Timing: when to file the election

To be treated as an S corp for a full calendar year, the election is generally due no later than two months and 15 days after the start of the tax year. For most small businesses, that means around March 15.

You can also elect for a new business within the same window after it starts. If you miss the deadline, the IRS has procedures for late election relief in some situations, but don't plan around that.

Many owners decide in the fourth quarter. October through December is a good time to run the numbers, because you can see most of the current year's profit and set up payroll before January.

North Carolina details worth knowing

A few points come up often for North Carolina owners:

  • Your LLC annual report doesn't go away. The Secretary of State annual report is still due every year, generally by April 15, whether or not you elect S corp status.
  • The state follows the federal election. North Carolina generally respects the federal S corp election, so you don't file a separate state election for that.
  • The pass-through entity tax election. North Carolina allows certain pass-through businesses, including S corps, to elect to pay state income tax at the entity level. Some owners use it as a workaround for the federal cap on state and local tax deductions. It has its own rules and deadlines, so ask about it when you run the numbers.
  • Withholding for yourself. Once you're on payroll, North Carolina income tax gets withheld from your salary like any other employee. Many owners forget to adjust their estimated payments for the distribution side.

Questions to ask before you elect

Take these to your tax preparer:

  1. What would my reasonable salary be, and how did you get that number?
  2. What's my estimated payroll tax savings at that salary?
  3. What will payroll, the extra tax returns and the franchise tax cost me each year?
  4. Does the election change my qualified business income deduction?
  5. Should I consider the North Carolina pass-through entity tax election?
  6. Do I need to clean up my books before the switch?
  7. Are there plans for new owners or investors that would make an S corp a bad fit?

If the person recommending the election can't answer the first three clearly, get a second opinion.

A worked example with real numbers

Say your single-member LLC in Raleigh nets $100,000 in 2026. As a regular LLC, self-employment tax applies to 92.35% of that profit at 15.3%, which comes to about $14,130.

Now say you elect S corp status and pay yourself a $55,000 salary that you can defend as reasonable for your role. Payroll taxes on the salary run 15.3% split between you and the company, about $8,415 in total. The remaining $45,000 comes out as a distribution with no payroll tax on it. On paper that saves roughly $5,715.

Then subtract the new costs: a payroll service (often $600 to $1,500 a year), the separate Form 1120-S return, NC unemployment insurance on your wages, and the North Carolina franchise tax, which has a $200 minimum for corporations. If those add up to $3,000, the real gain is closer to $2,700. At $60,000 of profit the same math can come out near zero, which is why we run it before anyone files Form 2553.

The short version

  • An LLC is a legal entity. An S corp is a tax election. Your LLC can elect S corp status.
  • The savings come from paying payroll taxes on a reasonable salary instead of all profit.
  • Setting salary too low is risky. Setting it too high erases the benefit.
  • Running an S corp adds payroll, extra returns, North Carolina franchise tax and higher fees.
  • Steady, comfortably high profit is when it tends to pay off.
  • Run the numbers in Q4 so you're ready for the March deadline.
