Should I Be an LLC or Sole Proprietorship? A CPA's Complete Guide for Small Business Owners (2026)

Starting a business is exciting, but one of the first questions almost every entrepreneur asks is:
"Should I stay a sole proprietor or form an LLC?"
It's a great question—and unfortunately, it's also one of the most misunderstood topics in business.
Every year, I meet business owners who formed an LLC because someone on TikTok told them they would "save thousands in taxes." Others remain sole proprietors because they believe an LLC is complicated and expensive.
The truth lies somewhere in the middle.
The decision between operating as a sole proprietorship or creating a Limited Liability Company (LLC) should be based on legal protection, tax implications, administrative requirements, long-term business goals, and risk—not internet myths.
Let's break down exactly how each option works using the Internal Revenue Code, Treasury Regulations, and state business law so you can make the right decision.
What Is a Sole Proprietorship?
A sole proprietorship is the default business structure under federal tax law.
If you start mowing lawns, detailing cars, designing websites, selling products online, consulting, or freelancing without creating a legal entity, congratulations—you are already a sole proprietor.
No paperwork is required to create one.
From the IRS's perspective, you and your business are legally the same taxpayer.
Income and expenses are reported on:
IRS Schedule C
Form 1040
Net profit then flows directly onto your individual tax return.
This treatment is authorized under the Internal Revenue Code and implemented through IRS Schedule C filing requirements.
What Is an LLC?
A Limited Liability Company (LLC) is not a tax classification.
This is probably the biggest misconception business owners have.
An LLC is created under state law, not federal tax law.
For example, in Iowa, an LLC is organized under the Iowa Revised Uniform Limited Liability Company Act.
The IRS does not recognize "LLC" as its own tax entity.
Instead, the IRS uses what's commonly called the "check-the-box regulations" (Treasury Regulations §§301.7701-1 through 301.7701-3).
A single-member LLC is disregarded by default for federal income tax purposes.
That means:
Single Member LLC
↓
Disregarded Entity
↓
Files Schedule C
↓
Exactly like a sole proprietor
This surprises many people.
Does an LLC Save Taxes?
Usually...
No.
Let's look at an example.
Sarah owns a photography business.
Annual Revenue:
$95,000
Business Expenses:
$30,000
Net Profit:
$65,000
If Sarah operates as:
Sole Proprietor
Single-Member LLC
Her federal tax return is identical.
She reports:
Schedule C
Income Tax
Self-Employment Tax
The IRS taxes both businesses exactly the same.
The LLC did not create any automatic tax savings.
Then Why Do So Many People Form LLCs?
Because taxes are only one piece of the puzzle.
The primary reason to form an LLC is:
Liability protection.
That's why it's called a Limited Liability Company.
Understanding Liability Protection
Imagine you own a landscaping company.
An employee accidentally damages a client's retaining wall.
Repair cost:
$80,000
If you're operating as a sole proprietor:
The lawsuit is against you personally.
Potential assets at risk include:
Personal savings
Personal vehicle
Future wages
Non-exempt assets
Now suppose the same business operates through an LLC.
Generally speaking, the lawsuit is against the company.
Your personal assets may receive protection if you properly maintain the LLC as a separate legal entity and you have not personally guaranteed the obligation or engaged in misconduct.
This concept is often referred to as the corporate veil (even though LLCs are not corporations).
However, courts can "pierce the veil" if owners fail to respect the entity's separate existence—for example, by commingling personal and business funds or using the company to commit fraud.
An LLC is a valuable legal tool, but it is not an impenetrable shield.
When an LLC Does NOT Protect You
An LLC cannot protect you from:
Your own negligence
Professional malpractice
Fraud
Personally guaranteed loans
Payroll tax obligations
Certain trust fund tax liabilities
For example:
If you're a CPA who commits malpractice...
or
You're an electrician who installs wiring improperly...
an LLC generally does not eliminate your personal responsibility for your own professional actions.
Insurance remains essential.
Tax Comparison
Let's compare.
Sole Proprietor
Reports:
Schedule C
Self-Employment Tax
Individual Income Tax
Single-Member LLC
Reports:
Schedule C
Self-Employment Tax
Individual Income Tax
Notice something?
They're identical.
What About Self-Employment Tax?
Many people believe an LLC eliminates self-employment tax.
This is false.
Self-employment tax is imposed under Internal Revenue Code §1401.
The tax generally consists of Social Security and Medicare taxes on net earnings from self-employment.
For 2026, business owners generally pay:
Social Security tax (up to the annual wage base)
Medicare tax on all net earnings
Additional Medicare tax may apply above certain income thresholds
Whether you are:
Sole Proprietor
Single-Member LLC
Your Schedule C profit is generally subject to self-employment tax.
The LLC alone does not change this result.
When Can an LLC Actually Save Taxes?
An LLC may create tax planning opportunities only if it elects a different tax classification.
For example:
LLC
↓
Elects S Corporation taxation by filing Form 2553 (assuming eligibility and deadlines are met)
Now things change.
Instead of paying self-employment tax on all business profit, the owner may:
Pay themselves a reasonable salary (subject to payroll taxes)
Receive additional profits as distributions that are generally not subject to self-employment tax
Example:
Business Profit:
$180,000
Reasonable Salary:
$90,000
Remaining Distribution:
$90,000
Potential payroll tax savings may exist compared with treating the full amount as self-employment income.
However:
The IRS requires that shareholder-employees receive reasonable compensation. Artificially low salaries can attract IRS scrutiny.
This strategy also introduces payroll, additional tax filings, bookkeeping requirements, and administrative costs, so it is not appropriate for every business.
Costs of Forming an LLC
Every state has different filing fees.
Potential costs include:
Formation filing fee
Annual reports
Registered agent (if applicable)
Separate bookkeeping
Business bank account
Additional legal compliance
Many states require ongoing filings to keep an LLC in good standing.
Always review your state's current requirements.
When Staying a Sole Proprietor Makes Sense
Many businesses operate perfectly well as sole proprietorships.
Examples include:
Freelance writers
Graphic designers
Tutors
Virtual assistants
Hobby businesses becoming profitable
Low-risk consultants
If your liability exposure is low, your revenue is modest, and you're just starting out, remaining a sole proprietor may be reasonable while you build the business.
When Forming an LLC Makes Sense
An LLC often becomes more attractive when:
You're hiring employees
You're signing commercial leases
You're entering larger contracts
You own equipment or inventory
You have significant customer interaction
You operate in a higher-risk industry
You want added legal separation between yourself and the business
Common examples include:
Contractors
Construction companies
Real estate investors
Retail stores
Auto detailers
Landscapers
E-commerce businesses
Property managers
Common Myths
Myth #1: An LLC Automatically Lowers Taxes
False.
By default, a single-member LLC is taxed the same as a sole proprietor.
Myth #2: I Need an LLC Before I Can Write Off Expenses
False.
Ordinary and necessary business expenses may generally be deductible whether you're a sole proprietor or an LLC, provided the tax law requirements are met.
Myth #3: My House Can Never Be Taken If I Have an LLC
False.
Limited liability has exceptions, and personal guarantees, negligence, fraud, and certain legal claims can still expose personal assets.
Myth #4: Every Business Should Become an S Corporation
False.
An S corporation election can provide tax savings in the right circumstances, but it also adds complexity, payroll requirements, compliance obligations, and professional costs. It should be evaluated on a case-by-case basis.
Questions to Ask Yourself
Before forming an LLC, ask:
How much legal risk does my business have?
Will customers sue if something goes wrong?
Am I hiring employees?
Am I borrowing money?
Am I signing long-term contracts?
Do I anticipate substantial growth?
Would the added administrative work be worthwhile?
Your answers often matter more than your current revenue alone.
Real-World Example
Consider two entrepreneurs.
Jake – Lawn Care Business
Revenue:
$180,000
Employees:
4
Commercial equipment:
$150,000
Customer property:
Yes
Jake has significant operational and liability exposure. An LLC is generally worth serious consideration, along with appropriate insurance and professional guidance.
Emily – Online Book Reviewer
Revenue:
$18,000
No employees
No inventory
No customer visits
Minimal legal exposure
Emily may reasonably begin as a sole proprietor while monitoring the growth and risk profile of her business.
Final Thoughts
There is no one-size-fits-all answer.
A sole proprietorship is simple, inexpensive, and works well for many new businesses.
An LLC provides legal protections that may be valuable as your business grows, but it does not automatically reduce your federal taxes.
Choosing the right structure requires evaluating your business activities, legal risks, income level, future plans, and tax strategy together—not relying on social media sound bites.
If you're unsure which option is right for you, professional guidance can help you avoid costly mistakes and choose a structure that supports both your current needs and your long-term goals.
