S Corp vs LLC 2026: Complete Tax Comparison for Small Business Owners
S Corp vs LLC for 2026: tax savings, reasonable salary rules, formation requirements, and when each structure makes sense. Includes real tax calculations.

An LLC's biggest tax benefits are pass-through taxation (no corporate double tax) and the 20% Qualified Business Income (QBI) deduction, which the 2025 OBBBA made permanent and which gives the full 20% below $201,750 of taxable income for single filers, $201,775 for married filing separately, and $403,500 for married filing jointly in 2026. A profitable LLC can also elect S-corp status to cut self-employment tax, expense up to $2,560,000 of equipment under Section 179, and deduct every ordinary business expense. The LLC structure itself changes nothing about your taxes; the savings come from these elections and deductions.
Key takeaways:
Key advantages available to LLC owners:
Tax savings potential (single-member LLC, $100,000 net profit): the QBI deduction (20%) saves roughly $4,000-$6,000 in income tax, an S-corp election saves about $4,000 in self-employment tax, and business deductions typically add $10,000-$30,000 of deductible expenses. Combined, that is $18,000-$40,000 or more in reduced taxable income.
Legal basis: IRC §199A (QBI), IRC §301.7701-3 (entity classification), IRC §1361 (S Corp election), IRC §179 (expensing)

The single biggest tax advantage of an LLC is pass-through taxation. Unlike a C Corporation, which pays corporate income tax and then shareholders pay tax again on dividends, an LLC's income is taxed only once, on the owner's personal return.
A single-member LLC is treated as a "disregarded entity" by the IRS. All income and expenses flow directly to Schedule C on your Form 1040. A multi-member LLC files Form 1065 and issues each member a Schedule K-1.
C Corporations face an effective double tax:
A C corporation is taxed twice on $100,000 of profit. It pays $21,000 in corporate income tax (21%), leaving $79,000, and the owner then pays $11,850 in qualified-dividend tax (15%) on that distribution, for total tax of $32,850 (a 32.85% effective rate). An LLC's pass-through owner pays about $14,130 in self-employment tax and about $12,657 in federal income tax on the same $100,000, for total tax of $26,787 (26.79%). That is roughly $6,063 less.
The LLC advantage grows at higher income levels because the corporate rate stays flat at 21% while pass-through income benefits from the QBI deduction and graduated individual tax rates.
Legal citation: IRC §301.7701-2 and §301.7701-3 establish default pass-through treatment for LLCs.
The Qualified Business Income deduction under IRC §199A lets LLC owners deduct up to 20% of their qualified business income from their taxable income. This deduction was made permanent by the One Big Beautiful Bill Act (OBBBA), signed July 4, 2025.
| Item | 2026 Amount |
|---|---|
| Maximum deduction | 20% of QBI |
| Full-deduction threshold (single / HOH) | $201,750 |
| Full-deduction threshold (married filing separately) | $201,775 |
| Full-deduction threshold (MFJ) | $403,500 |
| Phase-in range (single / HOH) | $201,750–$276,750 |
| Phase-in range (married filing separately) | $201,775–$276,775 |
| Phase-in range (MFJ) | $403,500–$553,500 |
| Minimum deduction (active business, QBI ≥ $1,000) | $400 |
Single filers and married-filing-separately filers have different thresholds ($201,750 vs $201,775): the two are not interchangeable. Above the threshold, the wage-and-property limits and the specified-service-business (SSTB) rules begin to phase in; below it, every LLC owner gets the full 20%. These figures come from IRS Rev. Proc. 2025-32.
Net business income: $80,000. The QBI deduction is 20% of qualified business income, capped at 20% of taxable income. Without QBI, taxable income is $80,000 − $16,100 standard deduction = $63,900, and 2026 federal income tax is about $8,800. The QBI deduction here is roughly $12,800 (20% of $63,900, because taxable income is below the $80,000 of income), which drops taxable income to about $51,100 and federal tax to about $6,000. That is a QBI savings of roughly $2,800 a year at this income level.
The QBI deduction is available whether you take the standard deduction or itemize, it's an additional deduction, not part of either.
For a complete breakdown, see our QBI deduction guide.
Important for S Corp owners: If your LLC has elected S Corp status, only the pass-through distribution qualifies for QBI, not your W-2 salary. This is a factor when calculating whether the S Corp election makes sense for your situation.
Legal citation: IRC §199A establishes the QBI deduction. OBBBA (P.L. 119-21) made it permanent, removing the pre-2026 sunset, and added the $400 minimum deduction for an active business with QBI of $1,000 or more.
An LLC can elect to be taxed as an S Corporation by filing Form 2553 with the IRS. This is arguably the most powerful tax benefit available to profitable LLC owners.
As a default LLC, you pay 15.3% self-employment tax on all net profit. With the S Corp election, you pay yourself a reasonable salary (subject to payroll taxes) and take remaining profit as distributions, which skip the 15.3% FICA tax.
On $120,000 of net profit: a default LLC pays $16,956 in self-employment tax ($120,000 × 92.35% × 15.3%). An S-corp paying a $65,000 salary pays $9,945 in payroll tax (15.3% of $65,000) and takes the remaining $55,000 as a distribution with no FICA, a FICA savings of $7,011 a year. After roughly $2,500 in S-corp costs, the net savings is about $4,511.
The S Corp election makes financial sense when net profit consistently exceeds $50,000-$60,000, the point where FICA savings outweigh the added cost of payroll processing and corporate tax filing.
For a detailed comparison, see our S Corp vs LLC guide. For the filing mechanics and late-election relief, see the Form 2553 S-Corp Election Guide and How to Convert an LLC to S-Corp.
Legal citation: IRC §1362 governs the S Corp election process. Form 2553 deadline for 2026: March 16, 2026.
Unlike any other business structure, an LLC can choose how it's taxed. This flexibility is unique to LLCs and is one of their strongest advantages.
| Classification | How to Elect | Best For |
|---|---|---|
| Disregarded entity (default, single-member) | Automatic | Under $50K profit, simplicity |
| Partnership (default, multi-member) | Automatic | Multiple owners, flexible allocation |
| S Corporation | File Form 2553 | $60K+ profit, reducing SE tax |
| C Corporation | File Form 8832 | Retaining earnings, venture funding |
You can change your tax classification as your business evolves. Started as a simple freelancer filing Schedule C? When profits grow, elect S Corp status. Raising venture capital? Switch to C Corp treatment.
Sole proprietorships and partnerships can't do this. A sole proprietor is always a sole proprietor. A general partnership is always a partnership. Only an LLC (and corporations) can elect different tax treatment.
Legal citation: IRC §301.7701-3 allows LLCs to elect their tax classification via Form 8832.
LLC owners can deduct all "ordinary and necessary" business expenses under IRC §162, reducing their taxable income dollar-for-dollar.
| Deduction | Description | Potential Savings |
|---|---|---|
| Home office | Dedicated space for business | $1,500-$5,000/year |
| Vehicle/mileage | Business driving at 72.5 cents/mile (2026) | $2,000-$10,000/year |
| Health insurance | Self-employed health insurance deduction | $5,000-$30,000/year |
| Retirement contributions | SEP IRA, Solo 401(k), SIMPLE IRA | Up to $72,000/year (2026) |
| Business insurance | Liability, professional, E&O | $500-$5,000/year |
| Professional services | CPA, attorney, bookkeeping | $1,000-$10,000/year |
| Software and tools | Business software subscriptions | $500-$5,000/year |
| Marketing | Advertising, website, promotion | $1,000-$20,000/year |
While sole proprietors can also claim these deductions, the LLC structure provides better documentation and separation of personal and business expenses, which matters during an audit.
For detailed guidance on deductible expenses, see our Schedule C instructions guide.
Legal citation: IRC §162 defines deductible business expenses. IRC §280A covers home office deductions.
LLC owners can immediately deduct the cost of qualifying business assets instead of depreciating them over several years. For 2026, the limits are generous:
| Item | 2026 Limit |
|---|---|
| Maximum Section 179 deduction | $2,560,000 |
| Phase-out threshold | $4,090,000 |
| Bonus depreciation rate | 100% (permanent under OBBBA) |
Buy $50,000 of business equipment for your LLC. Without Section 179, you depreciate it over 5-7 years, a first-year deduction of about $7,000-$10,000. With Section 179, you deduct the full $50,000 in year one, worth about $12,000 in tax at the 24% bracket.
For assets you can't deduct under Section 179, 100% bonus depreciation, made permanent by OBBBA for property acquired and placed in service after January 19, 2025, provides a full first-year write-off.
For more details, see our Section 179 depreciation guide.
Legal citation: IRC §179 establishes the expensing election. 2026 limits set by Rev. Proc. 2025-32; 100% bonus depreciation restored by OBBBA (IRC §168(k)).
Multi-member LLCs have a unique advantage: they can allocate profits and losses among members in proportions that differ from ownership percentages. This is called "special allocation" and it's governed by the LLC's operating agreement.
In a corporation, profits must be distributed proportionally to share ownership. If you own 50% of the stock, you get 50% of the dividends.
In an LLC, the operating agreement can specify different allocation ratios:
In a corporation with 50/50 ownership, each member gets 50% of profits. In a two-member LLC, the operating agreement can instead allocate 70% of profits to the member who provides most of the work and 30% to the member who provides most of the capital, as long as the split has "substantial economic effect" under §704(b).
Special allocation allows multi-member LLCs to:
Limitation: Special allocations must have "substantial economic effect" under IRC §704(b). The IRS will disregard allocations that exist solely to reduce taxes without reflecting the actual economic arrangement.
Legal citation: IRC §704(b) and Treas. Reg. §1.704-1(b)(2) govern partnership allocation rules.
For an honest picture, here's what an LLC does NOT automatically give you:
No automatic tax reduction. Forming an LLC doesn't lower your tax rate. A single-member LLC pays the same taxes as a sole proprietor by default. The tax benefits come from elections and deductions, not from the LLC structure itself.
No escape from self-employment tax. Unless you elect S Corp status, you still pay 15.3% SE tax on all net profit. The LLC doesn't change this.
No protection from income tax. LLC income is still taxed as ordinary income at your marginal rate. There's no special "LLC tax rate."
No free compliance. LLCs have annual filing requirements, state fees, and potential franchise taxes. California charges $800/year regardless of income. See our LLC annual fee calculator for your state.
Problem: Many new business owners form an LLC expecting an immediate tax break. Online formation services reinforce this by marketing "LLC tax savings" without explaining that default tax treatment is identical to a sole proprietorship.
Impact: Paying $300+ in formation fees and $100-$800 in annual state fees with no actual tax benefit.
Solution: Understand that LLC tax benefits come from specific elections (like S Corp) and proper use of deductions, not from the LLC structure itself.
Problem: LLC owners don't claim the QBI deduction because they don't know it exists or assume their tax software handles it.
Impact: Leaving a 20% deduction on the table. At $80,000 net profit, that's $16,000 in reduced taxable income, roughly $3,500 in tax savings.
Solution: Verify that your tax return includes the QBI deduction on Form 8995 or 8995-A. If you're using tax software, confirm the deduction appears. If you have a CPA, ask specifically about it.
Problem: LLC owners hear about S Corp tax savings and file Form 2553 before their profit justifies the added complexity and cost.
Impact: Spending $2,000-$4,000/year on payroll and tax prep while saving only $1,000-$1,500 in FICA taxes.
Solution: Run the numbers first. The S Corp election typically breaks even around $50,000-$60,000 in net profit. Below that, keep the simplicity of default LLC taxation.
Problem: LLC owners skip retirement contributions because they think only employees of large companies have access to tax-advantaged retirement accounts.
Impact: Missing deductions of $7,000-$70,000+ per year depending on the plan type.
Solution: Self-employed LLC owners can contribute to SEP IRAs (up to 25% of net earnings, max $72,000 for 2026), Solo 401(k) plans (up to $24,500 in employee deferral for 2026 plus employer contributions, to a $72,000 combined limit), or SIMPLE IRAs ($17,000 for 2026 plus employer match). See our retirement plan deductions guide.
Claiming every deduction you're entitled to requires tracking every business expense throughout the year, not scrambling to reconstruct records at tax time. The difference between a well-documented LLC and a poorly documented one can be thousands of dollars in missed deductions.

LLC tax benefits are real, but they require action. The LLC structure itself doesn't reduce your taxes, it provides the framework for tax-saving strategies like the S Corp election, QBI deduction, and proper business expense tracking.
The key strategies:
The best time to optimize your LLC's tax position is before year-end, not at tax time. Review your situation quarterly and adjust as your business grows.
