How Are S Corps Taxed? Complete Guide

If you’re running a business and wondering whether S corporation tax treatment makes sense for you, you’re asking the right question. The way your business gets taxed can save you thousands of dollars — or cost you thousands if you get it wrong.

Here’s what we’ll cover: how S corp taxation actually works (without the jargon), how it compares to other business structures, and when the math starts making sense for your situation.

Important disclaimer: This is educational content, not tax advice. Your situation is unique — work with a CPA for specific numbers and strategies that fit your business.

The Basics — No Jargon Version

An S corporation isn’t really a business entity type — it’s a tax election. You can form an LLC or a regular corporation, then elect S corp tax treatment by filing Form 2553 with the IRS.

Here’s the core concept: S corps are “pass-through” entities for tax purposes. The business itself doesn’t pay federal income tax. Instead, all profits and losses pass through to the owners’ personal tax returns.

But there’s a catch that makes S corps different from other pass-through entities: if you’re actively working in the business, you must pay yourself a “reasonable salary” as an employee. You pay payroll taxes (Social Security and Medicare) on that salary. Any remaining profits get distributed to you as a shareholder, and those distributions don’t face payroll taxes.

That’s where the potential tax savings come from — splitting your total business income between salary (subject to payroll taxes) and distributions (not subject to payroll taxes).

What Most People Get Wrong

The biggest misconception is that S corp status automatically saves you money. It doesn’t. It only saves money if your business is profitable enough that the payroll tax savings exceed the extra costs of running payroll and filing additional tax forms.

Another common mistake: thinking you can pay yourself a tiny salary and take the rest as distributions. The IRS requires “reasonable compensation” for work you actually do. If you’re the main person running a $200,000 consulting business, you can’t pay yourself $20,000 and call the rest distributions.

How Different Entity Types Handle Business Income

Let’s walk through how a $100,000 annual profit gets taxed under different structures:

Sole Proprietorship / Single-Member LLC

You pay income tax on the full $100,000 plus self-employment tax (Social Security and Medicare taxes) on the full amount. Self-employment tax runs about 15.3% on the first $160,000 or so of income (the exact threshold changes annually).

Total additional taxes beyond income tax: about $15,300 in self-employment tax.

multi-member LLC

Same as single-member LLC if you’re actively involved in the business. You’ll receive a K-1 showing your share of profits, and you pay income tax plus self-employment tax on your portion.

S Corporation

You must pay yourself a reasonable salary. Let’s say that’s $60,000 for this business. You pay:

• Payroll taxes on $60,000 (about $9,180 — you pay half as the employee, the business pays half)
• Income tax on the full $100,000
• No additional payroll taxes on the remaining $40,000 in distributions

Total payroll taxes: about $9,180 instead of $15,300.

Annual savings: roughly $6,120 in this example.

C corporation

The corporation pays corporate income tax on profits. Then if you take distributions (dividends), you pay personal income tax on those too. This “double taxation” is why most small businesses avoid C corp status unless they’re planning to reinvest profits in the business rather than distribute them.

The S Corp Decision

The math gets interesting when your business profits are high enough that the payroll tax savings exceed the extra costs of S corp treatment.

What the Election Actually Does

Filing Form 2553 tells the IRS you want pass-through taxation with the salary requirement. You get the benefits of avoiding double taxation (like an LLC) but with potential payroll tax savings on distributions.

Salary vs. Distribution in Practice

The IRS doesn’t publish exact formulas for “reasonable salary,” but they look at what similar businesses pay for similar work. If you’re a consultant, what do consulting firms pay people who do your type of work? If you’re running a product business, what do similar companies pay their operations managers or CEOs?

A common rule of thumb: salary should be at least 40-60% of your total business income if you’re the primary worker. But this varies dramatically by industry and role.

When the Math Starts Making Sense

Generally, S corp election becomes worth considering when your business profits exceed $60,000-80,000 annually and you expect that level to continue. Below that, the extra costs often outweigh the savings.

The break-even point depends on:

• How much you’d need to pay yourself as reasonable salary
• Your state’s payroll tax requirements
• The cost of running payroll and additional tax prep

Ongoing Costs to Consider

S corp treatment isn’t free. You’ll pay for:

• Monthly or quarterly payroll processing ($50-200+ per month)
• Additional CPA fees for corporate tax return preparation ($500-2,000+ annually)
• Possible state corporate filing fees
• More complex bookkeeping

Making the Election

File Form 2553 within 75 days of forming your business or by March 15 of the tax year you want the election to take effect. Miss the deadline, and you’re stuck waiting until the following tax year.

You can revoke S corp status later, but there are rules about when you can elect it again.

State Tax Considerations

Federal S corp treatment doesn’t automatically mean your state will treat you the same way.

No-Income-Tax States

States like Texas, Florida, and Nevada don’t have personal income tax, but they might still have franchise taxes or other business fees that apply to corporations but not LLCs. Research your specific state’s rules.

Franchise Taxes and Minimum Fees

Some states charge annual franchise taxes based on your business type. California charges S corps a minimum $800 annually, for example. These fees can eat into your federal tax savings.

Where You Form vs. Where You Operate

You’ll generally owe taxes where you actually conduct business (where you have “nexus”), regardless of where you formed the entity. Forming in Delaware while operating in California doesn’t let you escape California taxes — it just means you might pay fees in both states.

When to Get Professional Help

Hire a CPA if any of these apply to you:

• Your business profits exceed $75,000 annually
• You have multiple business income streams
• You’re considering S corp election
• You operate in multiple states
• You have employees
• You’re unsure about reasonable salary amounts
• You’ve been doing your own taxes but your situation is getting complicated

CPA vs. EA vs. Tax Preparer

A CPA (Certified Public Accountant) has the broadest training and can help with business strategy beyond just tax prep. An EA (Enrolled Agent) specializes in tax issues and can represent you before the IRS. A basic tax preparer might be fine for simple returns but isn’t equipped for business tax strategy.

What to Ask When Hiring

• Do they have experience with businesses like yours?
• Can they help with tax planning, not just preparation?
• What’s their process for staying in touch throughout the year?
• How do they charge — flat fee or hourly?

Have your financial records organized before meeting with any tax professional. Clean books save you money on professional fees.

For International Founders

If you’re not a U.S. citizen or resident but own a U.S. business, the tax rules get complex quickly.

U.S. Tax Obligations

Foreign-owned U.S. businesses often need to file Form 5472 (Information Return of a 25% Foreign-Owned U.S. Corporation) even if no tax is owed. Miss this filing, and you face steep penalties.

S corp status might not be available to you depending on your residency status and the types of investors in your business.

Why You Need Specialized Help

International business taxation involves tax treaties, transfer pricing rules, and coordination between multiple tax systems. This isn’t DIY territory. Find a CPA who specializes in international tax issues — general business CPAs often aren’t equipped for these complexities.

Frequently Asked Questions

Can I elect S corp status for my LLC?
Yes. You keep your LLC legal structure but elect to be taxed as an S corporation. This gives you LLC flexibility with potential S corp tax savings.

How long does S corp election last?
Until you revoke it or become ineligible (for example, by having too many owners or the wrong types of owners). You can revoke the election, but there are waiting periods before you can elect again.

Do I need a separate business bank account with S corp election?
Yes. The IRS requires clear separation between business and personal finances when you’re being treated as a corporation for tax purposes, even if you’re legally an LLC.

What happens if I don’t pay myself a salary?
The IRS can reclassify your distributions as wages, making you liable for unpaid payroll taxes plus penalties and interest. They’ve been increasingly aggressive about this in recent years.

Can I make S corp election mid-year?
You can file Form 2553 mid-year, but the election typically takes effect the following tax year unless you file within 75 days of the beginning of the current tax year.

Is S corp status worth it for a side business?
Probably not. The ongoing costs of payroll and additional tax prep usually outweigh the savings for part-time businesses with lower profit levels.

Conclusion

S corporation tax treatment can provide real tax savings, but it’s not automatic. The decision depends on your profit levels, how much you’d need to pay yourself as reasonable salary, and your state’s specific tax rules.

The key is running the numbers for your specific situation before making the election. A good CPA can model different scenarios and help you understand when the timing makes sense.
