LLC vs Sole Proprietor Taxes: What Changes

Tax information in this article is for educational purposes only and does not constitute tax, legal, or financial advice. Tax laws change frequently, and individual circumstances vary. Consult a qualified tax professional or CPA for guidance specific to your situation.

Many freelancers assume that forming an LLC will change how they are taxed. In most cases, it does not. A single-member LLC is a “disregarded entity” for federal tax purposes, meaning the IRS treats it exactly like a sole proprietorship. The real tax differences emerge only when you elect a different tax classification. This guide explains what actually changes — and does not change — when you form an LLC.

Default Tax Treatment: Nothing Changes

Sole Proprietorship

Report income and expenses on Schedule C
Pay self-employment tax on net profit via Schedule SE
No separate business tax return
Income flows to your personal Form 1040

Single-Member LLC (Default)

Report income and expenses on Schedule C — same form
Pay self-employment tax on net profit via Schedule SE — same tax
No separate business tax return — same filing
Income flows to your personal Form 1040 — same treatment

The IRS explicitly states that a single-member LLC with no election to be treated as a corporation is a “disregarded entity.” Your federal tax obligations are identical to a sole proprietorship.

What DOES Change with an LLC

While federal taxes remain the same by default, forming an LLC provides non-tax benefits and some state-level tax implications:

Liability Protection

The primary reason to form an LLC is personal asset protection. An LLC creates a legal separation between your business and personal assets. If your business is sued, your personal bank accounts, home, and other assets are generally protected.

A sole proprietorship offers no such protection — your personal assets are fully exposed to business liabilities.

State Taxes and Fees

Many states charge LLC-specific taxes or fees that sole proprietors do not pay:

State	LLC Annual Fee	Notes
California	$800/year (franchise tax)	Plus income-based fee above $250K
New York	$25/year + publication requirement	Publication can cost $1,000+
Texas	No franchise tax under $2.47M revenue	Minimal impact for most freelancers
Florida	$138.75/year	Annual report filing
Delaware	$300/year	Popular for LLC formation
Wyoming	$60/year	Low-cost state

Banking and Professional Credibility

LLCs can open business bank accounts more easily
Some clients and platforms require contracts with a business entity
An LLC operating agreement formalizes your business structure

Electing Different Tax Treatment

The real tax changes happen when you elect a different classification for your LLC:

Option 1: S-Corporation Election (Form 2553)

By filing Form 2553, your LLC is taxed as an S-Corp. This can reduce self-employment tax by splitting your income into salary (subject to payroll taxes) and distributions (not subject to SE tax).

When it makes sense: Net SE income consistently exceeding $60,000–$80,000. See S-Corp Election for Freelancers: When It Saves Money.

Option 2: C-Corporation Election (Form 8832)

By filing Form 8832, your LLC is taxed as a C-Corp. This subjects profits to corporate tax (21%) and distributions to dividend tax (double taxation). Rarely beneficial for freelancers.

Default: Disregarded Entity (No Election Needed)

No filing required. The LLC is ignored for federal tax purposes. This is the default for single-member LLCs and the right choice for most freelancers.

Side-by-Side Tax Comparison

Feature	Sole Proprietor	LLC (Default)	LLC + S-Corp Election
Federal tax form	Schedule C	Schedule C	Form 1120-S + K-1
SE tax applies to	All net profit	All net profit	Reasonable salary only
Payroll required	No	No	Yes (for salary)
Separate tax return	No	No	Yes (Form 1120-S)
Quarterly estimates	Yes	Yes	Yes
Formation cost	$0	$50–$500 (varies by state)	$50–$500 + payroll setup
Annual state fees	$0 (usually)	$0–$800+ (varies by state)	Same as LLC + payroll costs
Liability protection	None	Yes	Yes

Tax Scenario: $100,000 Net Income

Sole Proprietor or LLC (Default)

Item	Amount
Net SE income	$100,000
SE tax (15.3% on 92.35%)	$14,130
Half-SE-tax deduction	$7,065
Taxable income (after standard deduction)	$76,835
Federal income tax	~$12,227
Total federal tax	~$26,357

LLC with S-Corp Election ($60,000 salary / $40,000 distribution)

Item	Amount
Payroll taxes on $60,000 salary	$9,180
Employer FICA (deductible)	$4,590
Taxable income (after standard deduction)	~$79,310
Federal income tax	~$12,780
Total federal tax	~$21,960
Tax savings vs. sole prop	~$4,397

Note: S-Corp requires additional costs (payroll service ~$500–$1,500/year, separate tax return ~$500–$1,500/year) that offset some savings.

When to Stay a Sole Proprietor

Your net income is below $50,000
You are testing a freelance business and not sure it will continue
You want zero administrative overhead
Your state has high LLC fees (California’s $800 minimum)

When to Form an LLC (Default Tax Treatment)

You want liability protection
You work in a field with lawsuit risk (consulting, construction, professional services)
Clients require you to have a business entity
Your state’s LLC fees are reasonable

When to Form an LLC and Elect S-Corp

Your net income consistently exceeds $60,000–$80,000
The SE tax savings exceed the added costs of payroll and tax preparation
You are comfortable with the administrative requirements

Key Takeaways

A single-member LLC is a disregarded entity — federal taxes are identical to a sole proprietorship by default
The LLC provides liability protection, not tax savings (in default mode)
S-Corp election is what changes the tax picture, reducing SE tax on distributions
State-level LLC fees can be significant (especially California’s $800 minimum)
Run the numbers before electing S-Corp status — the savings must exceed the added costs
