What Is an LLC and How Is It Taxed in 2026?

An LLC (Limited Liability Company) is one of the most popular business structures because it combines personal liability protection with tax flexibility. When you form an LLC in any state, the entity itself is separate from your personal assets. This means creditors cannot reach your personal bank account or property if the business faces lawsuits or debt.

For 2026 federal income tax purposes, the IRS does not recognize “LLC” as a tax classification. Instead, the IRS taxes your LLC based on how many owners it has and whether you have made a special election. By default, a single-member LLC is taxed as a sole proprietorship, while a multi-member LLC is taxed as a partnership. This pass-through taxation means the business itself does not pay federal income tax. Instead, all income “passes through” to the owners’ personal tax returns.

Default LLC Taxation Structure for 2026

For a single-member LLC in 2026, all business income flows to your personal tax return via Schedule C. You report your net profit (revenue minus business expenses) on this form. The entire net profit is subject to self-employment tax at a rate of 15.3% (12.4% for Social Security plus 2.9% for Medicare). Additionally, you can deduct one-half of your self-employment tax as a business expense on Form 1040.

For multi-member LLCs, the taxation is slightly different. Each member receives a Schedule K-1 from the partnership showing their distributive share of income and losses. That income is passed through to personal returns and is subject to the same self-employment tax treatment.

The 20% Qualified Business Income (QBI) deduction applies to LLC owners in 2026. This means you can deduct up to 20% of your qualified business income, subject to income limits. For single filers, the deduction begins to phase out at $182,100 of taxable income. For married couples filing jointly, the phaseout starts at $364,200. This permanent deduction is extremely valuable for self-employed professionals and small business owners.

What Is an S-Corporation and How Does It Work?

An S-Corporation is a tax election under IRS subchapter S. You cannot form an “S-Corp” directly; instead, you form a business entity (typically a corporation or LLC) and then file Form 2553 with the IRS to elect S-Corp tax treatment. This election converts your entity into an S-Corporation for federal tax purposes.

The S-Corp structure is a pass-through entity, similar to an LLC or partnership. However, the key difference is how the IRS treats income. An S-Corp requires you to split your business income into two categories: W-2 wages and distributions. This split is the source of massive tax savings for many business owners in 2026.

How S-Corp Income Splitting Works in 2026

As an S-Corp owner in 2026, you must pay yourself a “reasonable salary” through payroll. This salary is subject to both income tax and the full 15.3% self-employment tax (split equally between employer and employee portions). However, any profit beyond your salary can be distributed to you as a dividend. These distributions are NOT subject to self-employment tax.

Here is the critical tax advantage: distributions avoid the 15.3% self-employment tax entirely. If you earn $100,000 and allocate $60,000 as salary and $40,000 as distributions, the distributions escape self-employment tax. This saves approximately $6,120 in taxes (15.3% of $40,000) compared to an LLC structure.

Additionally, S-Corp income qualifies for the 20% QBI deduction in 2026. This deduction is now permanent under the One Big Beautiful Bill Act, providing additional tax relief.

Self-Employment Tax Differences Between LLC and S-Corp

Self-employment tax is the Social Security and Medicare tax paid by self-employed individuals. In 2026, the rate remains 15.3% of net self-employment income. This breaks down as follows: 12.4% for Social Security (on earnings up to a certain threshold) and 2.9% for Medicare (on all net earnings), plus an additional 0.9% Medicare tax for high-income earners.

Business Structure	Self-Employment Tax Rate 2026	Applicable Income
LLC (Default)	15.3%	All net business income
S-Corp	15.3%	W-2 wages only (not distributions)
Limited Partner*	0%	Partnership distributions (TX, LA, MS only)

*The Fifth Circuit ruling in 2026 clarified that true limited partners (under state law) in partnerships are exempt from self-employment tax. However, this ruling currently applies only to taxpayers in Texas, Louisiana, and Mississippi. Cases are pending in other circuits.

For an LLC owner earning $100,000, the self-employment tax is approximately $15,300 (15.3% of net income). The business owner can deduct 50% of this amount ($7,650) from gross income, but the full amount reduces the bottom line. For an S-Corp owner earning the same $100,000 but splitting it as $70,000 salary and $30,000 distributions, the self-employment tax applies only to the $70,000 salary. This saves $4,590 in self-employment taxes (15.3% of the $30,000 distribution).

The Reasonable Compensation Rule: S-Corp Strategy for 2026

The “reasonable compensation” rule is the single most important limitation on S-Corp tax savings in 2026. Under IRS regulations, S-Corp owners must pay themselves reasonable compensation for the services they provide to the business. If you own a profitable consulting firm earning $150,000 annually, you cannot pay yourself $5,000 in salary and take $145,000 in distributions. The IRS will challenge this and reallocate income to reasonable W-2 wages.

What Constitutes “Reasonable Compensation”?

The IRS examines several factors when determining if S-Corp compensation is reasonable:

• The nature and complexity of the work performed
• Industry standards for comparable positions
• The time devoted to the business
• The owner’s experience and qualifications
• The business’s profitability and financial condition
• How compensation compares to other years

As of 2026, the IRS has intensified audits of S-Corporation reasonable compensation claims, particularly in high-income service businesses. If your salary appears artificially low relative to your business’s profitability, expect IRS scrutiny. Courts have upheld substantial penalties and back taxes when taxpayers misuse S-Corp structures.

How Much Can You Save With an S-Corp Election in 2026?

The actual tax savings from an S-Corp election depend on several variables: your business’s net income, the reasonable salary you must pay yourself, your tax bracket, and the state taxes in your jurisdiction.

Net Business Income	Reasonable Salary Allocation	Estimated Annual Savings*
$75,000	$65,000 salary / $10,000 distributions	$1,500-$2,000
$150,000	$100,000 salary / $50,000 distributions	$5,000-$7,500
$300,000	$180,000 salary / $120,000 distributions	$15,000-$20,000

*Savings estimates are federal self-employment tax only. State taxes vary. Assumes the business owner contributes meaningfully to the business (making the salary reasonable).

To calculate your potential savings, start with your expected net business income. Then, estimate a reasonable salary based on your industry and role. The difference between net income and your salary is the distribution amount, which avoids self-employment tax. Multiply the distribution by 15.3% to see your tax savings. Then subtract the costs of forming and maintaining the S-Corp (payroll processing, accounting, additional tax prep). If savings exceed costs, an S-Corp makes sense for 2026.

Uncle Kam in Action: Real Savings Story

Client Profile: Tacoma-based marketing consultant, self-employed, managing multiple client contracts. 2025 income: $250,000. Business structure: Single-member LLC (default taxation).

The Challenge: As an LLC owner paying self-employment taxes on all $250,000 of net income, this consultant paid approximately $38,250 in self-employment taxes annually (15.3% of $250,000). While the 20% QBI deduction provided relief ($50,000 in deductible income), the consultant still faced a significant tax burden and wanted to optimize the business structure.

The Uncle Kam Solution: After analyzing the client’s business, we determined that a reasonable W-2 salary for this marketing consultant position in Tacoma was $160,000, based on industry standards, experience level, and time commitment. We elected S-Corp tax treatment effective January 2026, implementing the following income allocation:

• W-2 Salary: $160,000 (subject to 15.3% SE tax = $24,480)
• S-Corp Distributions: $90,000 (zero SE tax)
• Total Income: $250,000

The Results:

• Previous SE Tax (LLC): $38,250
• New SE Tax (S-Corp): $24,480
• SE Tax Savings: $13,770
• Less: S-Corp compliance costs (payroll, accounting, filing): $2,500
• Net Tax Savings for 2026: $11,270
• Return on Investment: 450% (2026 savings = $11,270 / setup cost of $2,500)

By electing S-Corp status, this marketing consultant reduced annual tax liability by $11,270 while maintaining proper reasonable compensation documentation. The 20% QBI deduction still applied to the $90,000 in distributions, providing an additional $18,000 in deductible income. The client’s total tax savings for 2026, including QBI benefits, exceeded $15,000.

Frequently Asked Questions

Can a Real Estate Investor Use an S-Corp to Reduce Taxes in 2026?

Real estate rental income generally does not benefit from the S-Corp structure. If your business is purchasing rental properties and collecting rent, that income is typically passive income, not subject to self-employment tax under current IRS rules. However, if you actively manage properties (not just hire a property manager) or provide real estate services like 1031 exchanges or cost segregation planning, an S-Corp election may provide benefits.

What Happens if the IRS Audits My S-Corp Reasonable Compensation in 2026?

If audited, the IRS may argue that your W-2 salary is unreasonably low compared to your business’s profitability or industry standards. If the IRS wins the audit, they will reallocate income to W-2 wages, increasing your self-employment tax liability, plus interest and penalties. Maintaining detailed documentation of your job duties, time logs, and comparable salary data is critical to defending your reasonable compensation claim.

Is the 20% QBI Deduction Permanent in 2026?

Yes. Under the One Big Beautiful Bill Act signed on July 4, 2025, the 20% Qualified Business Income deduction is now permanent. Previously, it was set to expire after 2025. For 2026, both LLC and S-Corp owners can deduct up to 20% of qualified business income, subject to income limits and taxable income limitations.

How Does the Fifth Circuit Limited Partner Ruling Affect My LLC in 2026?

In February 2026, the Fifth Circuit Court of Appeals ruled that true limited partners in partnerships are exempt from self-employment tax on their distributive share. This ruling applies in Texas, Louisiana, and Mississippi. If you are a limited partner in a partnership (structured as an LP or LLLP) under state law with genuine limited liability, you may not owe self-employment tax on partnership distributions. However, this does not apply to general partners or LLC members unless their structure qualifies as a true limited partnership.

When Should I File Form 2553 to Elect S-Corp Status for 2026?

To be effective for 2026 tax year, you should file Form 2553 by March 15, 2026. This is the safe harbor deadline. Filing after March 15 may still be accepted, but the election could be deemed effective for the following tax year. If you are in the middle of 2026 and just deciding to make the election, file Form 2553 immediately with a request for late election treatment, explaining the reason for the delay.

Can I Deduct Payroll Taxes for My S-Corp W-2 Salary in 2026?

Yes. As an S-Corp, payroll taxes (both employer and employee portions) are deductible business expenses. This is different from sole proprietors, who can only deduct half of self-employment taxes. The full payroll tax becomes a business deduction on Schedule C or the S-Corp Form 1120-S, reducing your taxable income further.

Do I Need to Have Employees If I Elect S-Corp Status in 2026?

No. Many S-Corp owners are the only employee. You simply run payroll for yourself, reporting your W-2 salary on Form 941 (payroll tax returns). You do not need to hire additional employees, though you may choose to if your business grows.

What is the IRS S-Corp Filing Deadline for 2026 Tax Returns?

S-Corporation tax returns (Form 1120-S) are due March 16, 2026. This is three weeks before the individual return deadline (April 15, 2026). If you need more time, you can request a six-month extension, moving the deadline to September 16, 2026, but taxes are still due by the original deadline to avoid penalties.
