Understanding S corp tax brackets is one of the smartest moves you can make as a business owner. Unlike C corporations that face double taxation, S corps pass income through to shareholders’ personal returns, which means you’re taxed at individual rates instead of corporate rates. The catch? You need to know exactly how these brackets work to actually save money. Let’s break down what you need to know in 2024.

What Are S Corps Exactly?
An S corporation is a tax election, not a business structure. You can form an LLC, partnership, or sole proprietorship and elect to be taxed as an S corp. The “S” refers to Subchapter S of the Internal Revenue Code, which allows small business owners to avoid the corporate income tax while maintaining liability protection.
Here’s the key difference: a standard C corporation pays taxes at the entity level (currently a flat 21% federal rate), then shareholders pay taxes again on dividends. An S corp doesn’t pay entity-level tax—instead, income flows to your personal tax return where you pay taxes at your individual rate. This is why understanding S corp tax brackets matters so much. Your individual brackets determine your actual tax burden.
The IRS limits S corp eligibility to 100 U.S. shareholders, and all shareholders must be U.S. citizens or residents. You also can’t have corporate or partnership shareholders.
Pass-Through Taxation Explained
Pass-through taxation is the secret sauce that makes S corps attractive. Instead of the business paying taxes, the income “passes through” to your personal return. You report your share of profits and losses on Schedule K-1, then include those numbers on your Form 1040.
This matters because you get taxed at your individual tax bracket, not a corporate rate. In 2024, federal S corp tax brackets for single filers range from 10% (on income up to $11,600) all the way to 37% (on income over $578,100). For married filing jointly, the brackets are wider, with the top rate kicking in at $693,750.
The beauty of pass-through taxation is flexibility. If your S corp has a loss year, that loss passes through to your return and can offset other income. If you have a profitable year, you control when and how much to distribute to yourself.
Federal Tax Brackets for 2024
Let’s look at the actual 2024 federal tax brackets. These are adjusted annually for inflation, so they’re different from 2023.
Single Filers:
- 10%: $0 to $11,600
- 12%: $11,600 to $47,150
- 22%: $47,150 to $100,525
- 24%: $100,525 to $191,950
- 32%: $191,950 to $243,725
- 35%: $243,725 to $609,350
- 37%: $609,350+
Married Filing Jointly:
- 10%: $0 to $23,200
- 12%: $23,200 to $94,300
- 22%: $94,300 to $201,050
- 24%: $201,050 to $383,900
- 32%: $383,900 to $487,450
- 35%: $487,450 to $731,200
- 37%: $731,200+
When you’re an S corp owner, your business income lands somewhere in these brackets. This is why strategic tax planning matters—you want to structure your income distribution to minimize bracket creep and take advantage of lower rates.
Self-Employment Tax Advantage
Here’s where S corps get really interesting. Self-employment tax is the biggest advantage most business owners see. As a sole proprietor or partnership, you pay 15.3% self-employment tax on net profit (12.4% for Social Security, 2.9% for Medicare). An S corp owner only pays payroll taxes on wages, not on distributions.
Let’s say your S corp nets $100,000. As a sole proprietor, you’d pay roughly $14,130 in self-employment tax. But if you’re an S corp owner and take a $60,000 salary with a $40,000 distribution, you only pay payroll taxes on the $60,000 salary portion. That’s a potential savings of around $5,700.
The catch? The IRS requires you to pay yourself a “reasonable salary” for the work you do. You can’t take a $1,000 salary and distribute $99,000 to avoid taxes. We’ll dive deeper into this in the next section.
Reasonable Salary Requirement
The IRS watches S corp owners closely on the reasonable salary requirement. You must pay yourself a reasonable salary for the actual services you perform. “Reasonable” typically means what someone in your industry, doing your job, would earn.
This is where corporate tax planning gets nuanced. If you run a consulting firm and bill $150 per hour, paying yourself $30,000 annually while distributing $200,000 will raise red flags. The IRS can reclassify distributions as wages, hit you with back taxes, penalties, and interest.
What’s reasonable varies by industry:
- Tech startups: $80,000-$150,000+ depending on role
- Service businesses: Often based on billable hours and rates
- Retail/e-commerce: Market rate for management roles
- Professional services: Comparable to employed professionals in your field
Document everything. Keep job descriptions, market research on comparable salaries, and records of hours worked. If audited, you’ll need evidence that your salary is defensible.
State Tax Considerations
Federal S corp tax brackets tell only half the story. Your state might also tax S corp income. Some states don’t tax business income at all (Texas, Florida, Nevada), while others have aggressive state income taxes (California at 13.3%, New York at 10.9%).
A few states impose a corporate-level tax on S corps even though they’re pass-through entities. For example, some states charge a franchise tax or corporate license fee regardless of profit. A handful require S corps to file separate state returns.
Here’s what you need to check:
- Does your state tax S corp income at individual rates?
- Are there corporate-level taxes on S corps?
- Do you owe taxes in multiple states if you have customers nationwide?
- Are there sales tax obligations based on your business model?
If you’re in a high-tax state, an S corp election might save you less than you’d think. But if you’re in a low or no-tax state, the federal self-employment tax savings become even more valuable.
Calculating Your Tax Liability
Here’s a practical example. Let’s say you’re a single filer running an S corp that nets $150,000 after expenses. You decide to take a $90,000 salary and distribute $60,000.
Your tax calculation:
- W-2 wages: $90,000
- Payroll taxes on wages: ~$13,770 (you and employer share)
- S corp distribution: $60,000
- Taxable income from S corp: $150,000
- Standard deduction (2024): $14,600
- Taxable income: $135,400
- Federal income tax at your bracket: approximately $24,500
- Total tax: roughly $38,270
Compare this to being a sole proprietor with $150,000 profit:
- Self-employment tax: ~$21,180
- Taxable income after SE tax deduction: $142,910
- Federal income tax: approximately $26,200
- Total tax: roughly $47,380
The S corp structure saves you around $9,000 in this scenario. That’s the power of avoiding self-employment tax on distributions. The actual savings depend on your income level, state taxes, and how much you can reasonably distribute versus pay as salary.
Common Mistakes to Avoid
We see business owners make the same S corp mistakes repeatedly. Here are the biggest ones:
Mistake #1: Ignoring the Reasonable Salary Rule Taking a tiny salary to minimize payroll taxes invites IRS scrutiny. They’ll reclassify distributions as wages, and you’ll owe back taxes plus penalties.
Mistake #2: Missing Payroll Tax Deadlines S corps must deposit payroll taxes on schedule (usually semi-weekly or monthly). Missing deposits triggers penalties quickly. Set up automatic deposits.
Mistake #3: Not Filing Form 2553 Correctly You elect S corp status by filing Form 2553 with the IRS. File it late or incorrectly, and your election might not be valid. Work with a tax professional here.
Mistake #4: Forgetting State S Corp Elections Electing S corp status federally doesn’t automatically apply to states. You often need to file separate state elections. Missing this means you might not get state tax benefits.
Mistake #5: Poor Record Keeping Keep detailed records of why you chose your salary amount, hours worked, and business decisions. Average cost of tax preparation by CPA increases dramatically if you can’t back up your tax positions.
Quarterly Estimated Taxes
As an S corp owner, you’ll likely need to pay quarterly estimated taxes. Unlike W-2 employees who have taxes withheld from paychecks, you’re responsible for making quarterly payments to the IRS.
Calculate your estimated tax by looking at your expected annual income and tax liability, then divide by four. The 2024 quarterly deadlines are:
- Q1 (Jan-Mar): Due April 15
- Q2 (Apr-Jun): Due June 17
- Q3 (Jul-Sep): Due September 16
- Q4 (Oct-Dec): Due January 15 (next year)
Missing estimated tax payments triggers penalties and interest. Plus, if you underpay significantly, you might face an underpayment penalty even if you ultimately owe less tax.
Pro tip: Many S corp owners pay themselves a regular W-2 salary with taxes withheld. This simplifies quarterly estimated tax calculations since withholding counts toward your estimated tax obligation.
Frequently Asked Questions
Are S corp owners taxed differently than sole proprietors?
Yes, significantly. S corp owners avoid self-employment tax on distributions, while sole proprietors pay 15.3% self-employment tax on all net profit. This typically saves $5,000-$15,000+ annually depending on income level. However, S corps require more administrative work and compliance.
What income level makes an S corp worthwhile?
Generally, an S corp makes sense when net profit exceeds $60,000-$80,000 annually. Below that, the administrative costs and complexity often outweigh the self-employment tax savings. Above that, the savings compound quickly.
Can I switch from S corp back to sole proprietor?
Yes, you can revoke your S corp election. However, there are timing rules and potential tax consequences. If you’ve been taking advantage of lower distributions, revoking might trigger unexpected tax bills. Consult a tax professional before making this change.
How does an S corp affect my personal tax brackets?
Your S corp income is added to any other income on your personal return. If you have W-2 wages plus S corp distributions, they stack together. This can push you into higher S corp tax brackets, so strategic income timing matters.
Do I need to file separate tax returns for my S corp?
Yes. Your S corp files Form 1120-S (corporate return) showing income and deductions. You receive a Schedule K-1 showing your share of profit. Then you report that K-1 income on your personal Form 1040. Both returns are required.
What if my S corp has a loss?
Losses pass through to your personal return and can offset other income. This is a major advantage in startup years or down years. However, passive loss limitations might apply if you’re not materially involved in the business.
Key Takeaways
Understanding S corp tax brackets and how they interact with your business structure can save you thousands annually. The main advantage is avoiding self-employment tax on distributions, which typically saves 15.3% on a portion of your income. However, this requires:
- Paying yourself a reasonable salary for work performed
- Handling payroll tax deposits and filings correctly
- Making quarterly estimated tax payments
- Maintaining detailed records and documentation
- Considering both federal and state tax implications
The S corp structure isn’t right for everyone. If your net profit is under $60,000, the administrative burden might outweigh savings. If you’re in a high-tax state, state-level taxes might reduce your advantage. But for profitable businesses with owners actively involved in operations, an S corp election frequently delivers significant tax savings.
We recommend working with a qualified tax professional to evaluate whether an S corp makes sense for your specific situation. They can model your numbers, ensure IRS compliance, and help you structure distributions strategically. The investment in professional guidance typically pays for itself many times over through proper tax planning and avoiding costly mistakes.
