LLC vs S-Corp: Which Saves You More on Taxes? (2026)

If your LLC is earning solid profits, you have probably heard that electing S-Corp status could save you thousands of dollars in taxes. But the reality is more nuanced than the internet gurus suggest. The LLC vs S-Corp decision depends on your net income, your willingness to handle additional compliance requirements, and whether the tax savings actually exceed the added costs.

This guide breaks down the real differences between an LLC taxed as a sole proprietorship (the default) and an LLC taxed as an S-Corp, with concrete numbers so you can see exactly when the S-Corp election makes financial sense and when it does not.

What Is an LLC (Default Tax Treatment)?

When you form a single-member LLC, the IRS treats it as a disregarded entity by default. This means the LLC itself does not file a separate tax return. Instead, all business income and expenses flow through to your personal tax return on Schedule C.

As the sole owner, you pay two types of tax on your net profit:

• Federal income tax — at your marginal rate (10% to 37% depending on your total taxable income)
• Self-employment (SE) tax — 15.3% on 92.35% of your net profit. This covers Social Security (12.4%) and Medicare (2.9%). You pay both the employee and employer halves.

For a multi-member LLC, the default classification is a partnership. The LLC files an informational return (Form 1065), and each member reports their share of income on their personal return via Schedule K-1. Self-employment tax still applies to each member’s share of income from the business.

The self-employment tax is where the LLC’s default structure becomes expensive for profitable businesses. Unlike W-2 employees whose employer pays half of the payroll tax, LLC owners pay the full 15.3% themselves. On $100,000 of net profit, that is roughly $14,130 in self-employment tax alone — before income tax.

What Is an S-Corp?

An S-Corp is not a separate type of business entity. It is a tax election that you make with the IRS by filing Form 2553. Your LLC remains an LLC in terms of legal structure, liability protection, and state law. The only thing that changes is how the IRS taxes the income.

When your LLC elects S-Corp status, the business becomes a separate taxpayer that files its own return (Form 1120-S). The key difference is how you receive money from the business:

• Salary (W-2 wages) — You must pay yourself a “reasonable salary” as an employee of the S-Corp. This salary is subject to payroll taxes (the same 15.3% split between employee and employer portions).
• Distributions — Any remaining profit after your salary can be distributed to you as a shareholder distribution. These distributions are not subject to self-employment or payroll tax. You only pay income tax on them.

This is where the tax savings come from: by paying yourself a reasonable salary that is less than your total net profit, the remaining distributions avoid the 15.3% self-employment tax.

Self-Employment Tax Savings: The Math

Let us walk through a concrete example to see exactly how much the S-Corp election saves.

Scenario: $100,000 Net Business Income

Scenario: $60,000 Net Business Income

With $60,000 in net profit and a $35,000 reasonable salary:

• LLC default SE tax: $60,000 x 92.35% x 15.3% = $8,478
• S-Corp payroll tax: $35,000 x 15.3% = $5,355
• Savings: $3,123 per year

After subtracting the additional cost of payroll service ($240-$600/yr) and higher tax preparation ($300-$1,000 more than Schedule C), the net savings are roughly $1,500-$2,500 per year. Still meaningful, but more modest.

Scenario: $30,000 Net Business Income

With $30,000 in net profit, you would need to pay a reasonable salary of approximately $25,000-$30,000, leaving little or no room for distributions. The added compliance costs would likely exceed any tax savings, making the S-Corp election counterproductive at this income level.

The “Reasonable Salary” Requirement

The IRS requires S-Corp owner-employees to receive a reasonable salary before taking any distributions. This is not optional — it is the most scrutinized aspect of S-Corp taxation.

A “reasonable salary” means compensation that is comparable to what other businesses pay for similar services. Factors the IRS considers include:

• The nature of the work you perform
• Your training, education, and experience
• Comparable salaries for similar roles in your industry and geographic area
• The time and effort you devote to the business
• The amount of income the business generates

What happens if your salary is too low? The IRS can reclassify some or all of your distributions as wages, which means you will owe back payroll taxes plus penalties and interest. The IRS has won multiple court cases on this issue, including cases where owners paid themselves $0 salary and took all income as distributions.

A common rule of thumb: set your salary at 40-60% of net business income, with a minimum that reflects the market rate for someone doing your job. For a freelance web developer earning $100,000 through their LLC, a salary of $50,000-$60,000 would generally be considered reasonable.

When the S-Corp Election Makes Sense

The S-Corp election is a good fit when:

• Your net business income consistently exceeds $40,000-$50,000 per year after all business expenses
• You can realistically set a reasonable salary that is lower than your total net income, leaving room for distributions
• You are willing to handle the compliance requirements — payroll processing, quarterly payroll tax filings (Form 941), annual Form 1120-S, and issuing yourself a W-2
• You plan to operate the business for multiple years — the setup cost of implementing payroll and the S-Corp tax structure is only worth it if you will benefit from the savings over time

The S-Corp election is NOT a good fit when:

• Your net income is below $40,000 (savings do not exceed compliance costs)
• Your income varies wildly from year to year (makes reasonable salary determination difficult)
• You are a solo freelancer who values simplicity over tax optimization
• You are in a state that does not recognize S-Corp status or imposes separate taxes on S-Corps

How to Elect S-Corp Status (Form 2553)

If you decide the S-Corp election is right for you, here is how to make it happen:

1. Ensure eligibility: Your LLC must have 100 or fewer shareholders (members), all of whom must be U.S. citizens or residents. You cannot have non-resident alien shareholders, and you cannot have corporate or partnership shareholders.
2. File IRS Form 2553 (Election by a Small Business Corporation). This form must be filed:
   • Within 75 days of the date you formed your LLC, OR
   • By March 15 if you want the election to apply for the current calendar year, OR
   • Any time during the preceding tax year (the election takes effect the following year)
3. Set up payroll: Once the election is effective, you must run payroll for yourself. Use a payroll service like Gusto ($20-$40/mo), ADP, or QuickBooks Payroll.
4. Begin paying yourself a salary: Issue regular paycheck(s) with proper tax withholding.
5. File Form 1120-S annually: The S-Corp files its own tax return, and you receive a K-1 showing your share of income.

S-Corp Compliance Requirements

Running an S-Corp adds administrative overhead compared to a default LLC. Here is what you need to stay on top of:

Requirement	Frequency	Cost
Payroll processing	Monthly or biweekly	$20-$50/month
Quarterly payroll tax filings (Form 941)	Quarterly	Included in payroll service
W-2 and W-3 filing	Annual (January)	Included in payroll service
Form 1120-S tax return	Annual (March 15)	$500-$1,500 (CPA)
State S-Corp/LLC annual report	Annual or biennial	Varies by state
Reasonable salary documentation	Ongoing	Free (keep records)

Cost of Running S-Corp vs LLC: Annual Comparison

Annual Expense	LLC (Default)	S-Corp
Tax preparation	$200-$500	$700-$2,000
Payroll service	$0	$240-$600
Bookkeeping (additional complexity)	$0-$200	$200-$500
Total additional S-Corp cost	—	$940-$2,600/yr

For the S-Corp election to make sense, your tax savings must exceed these additional compliance costs. At $100,000 net income with $6,480 in annual SE tax savings, the math clearly works. At $40,000, it likely does not.

Frequently Asked Questions

Can I switch my LLC to an S-Corp at any time?

You can elect S-Corp status at any time by filing IRS Form 2553. However, for the election to be effective for the current tax year, you must file within 75 days of the start of the tax year (by March 15 for calendar-year filers). If you miss the deadline, the election takes effect the following tax year. The IRS does grant late election relief in some circumstances if you can show reasonable cause.

What is the minimum salary for an S-Corp owner?

The IRS does not specify a minimum dollar amount. Instead, your salary must be ‘reasonable’ based on what other employers pay for comparable work in your industry and region. The IRS looks at factors like the services you provide, your experience, time devoted to the business, and comparable salaries. As a general guideline, most tax professionals recommend setting the salary at 40-60% of net business income with a minimum that reflects market rates for your role.

Do I need a CPA to run an S-Corp?

While not strictly required, most S-Corp owners work with a CPA or tax professional. Form 1120-S is more complex than Schedule C, and mistakes can trigger IRS scrutiny. A CPA typically charges $500-$1,500 to prepare an S-Corp tax return. If your S-Corp saves you $5,000+ in taxes annually, this is a worthwhile investment.

Can a multi-member LLC elect S-Corp status?

Yes. A multi-member LLC can elect S-Corp status as long as it meets the eligibility requirements: 100 or fewer members, all of whom are U.S. citizens or residents, and no corporate or partnership members. Each member-employee must receive a reasonable salary.

Does S-Corp status affect my LLC’s liability protection?

No. The S-Corp election only changes how the IRS taxes your income. Your LLC retains all of its legal protections, including limited personal liability for business debts and obligations. Your operating agreement, registered agent, and state compliance requirements remain the same.
