LLC vs S-Corp Tax Comparison 2026

Your Freelance Income Hit $100K — Your Accountant Says "Consider an S-Corp." Here's the Math.

You've been running a single-member LLC or sole proprietorship. Your net freelance income crossed $100,000 this year. At a routine meeting, your accountant mentioned an S-Corp election could save you "a few thousand dollars."

That vague answer cost them your trust. Here's the specific number: at $100,000 net profit with a $60,000 "reasonable salary," an S-Corp saves approximately $6,120 per year in self-employment taxes. The question is whether that savings justifies the added complexity and cost.

How the Self-Employment Tax Savings Actually Work

As a sole proprietor or single-member LLC, your entire $100,000 net profit is subject to self-employment tax:

• SE tax on $100K: $100,000 × 0.9235 × 0.153 = $14,130

As an S-Corp owner with a $60,000 salary:

• Payroll taxes on $60,000 salary: $60,000 × 0.153 = $9,180 (split between you and the corp, but you pay both sides as owner)
• $40,000 passes through as profit distribution: Zero SE tax on this amount
• Total: $9,180

Annual savings: $14,130 - $9,180 = $4,950

But wait — there's a 0.9235 multiplier for the SE deduction. The actual net SE tax difference runs closer to $6,000-$8,000 when you factor in the deductibility mechanics at different income levels.

What "Reasonable Salary" Actually Means

The IRS requires S-Corp owner-employees to pay themselves a "reasonable salary" before taking profit distributions. This isn't a number you pick to maximize tax savings — it's supposed to reflect what a similarly qualified employee would earn for the same work.

For a freelance web developer earning $100K: a reasonable salary is probably $55,000-$70,000 based on W-2 salary data for similar roles.

For a freelance writer earning $100K: a reasonable salary might be $45,000-$55,000 (writers earn less as employees).

The IRS audits S-Corps with suspiciously low salaries. A $1 salary on $100K profit is a red flag. A $40,000 salary on $100K profit in a high-skill profession is defensible but aggressive. $60,000 on $100K is conservative and audit-resistant.

The savings evaporate entirely if you set the salary too high. At a $100,000 salary on $100,000 profit, you'd pay SE tax on the full amount — same as a sole proprietor.

The Real Costs of Running an S-Corp

S-Corp election eliminates SE tax savings unless the overhead stays below the savings:

Annual costs you don't have as a sole proprietor:

• State franchise/registration fee: $0 (Wyoming, Montana) to $800/year (California)
• Payroll processing: $500-$1,200/year (Gusto, QuickBooks Payroll, etc.)
• Business tax return (Form 1120-S): $750-$1,500/year from a CPA (vs. $300-$600 for a Schedule C)
• Additional bookkeeping complexity: $0 if you DIY, $200-$400/year in additional time

Estimated total overhead: $1,500-$3,500/year depending on state and whether you use a CPA.

At $100K net profit with $4,950 in SE tax savings, your net benefit after overhead is roughly $1,500-$3,450. Still positive — but the break-even analysis changes dramatically by state. California charges $800/year just to have the entity, before any payroll costs.

The Income Crossover Point

Below $50,000 in net profit, S-Corp overhead almost always exceeds SE tax savings. The numbers:

• $50K net, $35K salary: SE tax savings ≈ $2,295. After $2,000+ overhead: marginal or negative.
• $75K net, $50K salary: SE tax savings ≈ $3,825. After $2,000 overhead: net +$1,825.
• $100K net, $60K salary: SE tax savings ≈ $4,950. After $2,000 overhead: net +$2,950.
• $150K net, $80K salary: SE tax savings ≈ $9,180. After $2,000 overhead: net +$7,180.

Most tax professionals cite $60,000-$80,000 in net profit as the general breakeven point. At $100K, the S-Corp election is clearly worth it in most states.

How to Make the S-Corp Election

You don't form an "S-Corp" directly — you form an LLC or C-Corp and elect S-Corp tax treatment:

1. Form an LLC in your state (or use your existing LLC)
2. File IRS Form 2553 within 75 days of formation, or by March 15 for the current tax year
3. Set up payroll (you must run payroll, not just move money between accounts)
4. File quarterly payroll taxes (Form 941) and an annual business return (Form 1120-S)

The election is effective for the tax year you specify on Form 2553. Miss the March 15 deadline for the current year and you wait until next year, unless you qualify for late election relief (IRS Revenue Procedure 2013-30 covers this).

What the S-Corp Doesn't Fix

Taxes are one factor in the LLC vs S-Corp decision, but not the only one. The S-Corp structure adds complexity that matters:

Multi-member LLCs: If you have business partners, each partner's "reasonable salary" must be determined separately. Partner-owners cannot be passive investors if they want to avoid payroll taxes — the IRS scrutinizes arrangements where some partners draw salaries and others take only distributions.

Growing businesses: S-Corps can have at most 100 shareholders, all of whom must be US citizens or residents. If you plan to raise venture capital from foreign investors or want to issue multiple share classes, an S-Corp election is incompatible — you'd need to dissolve it and operate as a C-Corp. Many fast-growth startups skip S-Corp entirely for this reason.

Exit strategy: When you sell an S-Corp business, the tax treatment of the sale proceeds depends on whether you structure it as an asset sale or stock sale. An LLC taxed as a partnership generally offers more flexibility in structuring favorable asset allocations at sale.

For a solo consultant at $100K in revenue with no plans for investors or partners, none of these concerns apply. The S-Corp election is straightforward and the tax savings are real.
