If your sole proprietorship has been growing steadily, that is a great sign. As your business becomes more successful, you may reach a point where your current setup no longer gives you everything you need.
A major limitation of a sole prop is that there is no legal separation between you and your business. If the business takes on debt or faces legal action, your personal assets could be at risk.
That is why many business owners eventually explore S corporation status. An S corporation can offer liability protection along with tax planning opportunities for businesses that have reached a consistent level of profitability. This guide walks through when it makes sense to make the switch and what the process looks like.
Business entity types
There are several ways to structure a business. Here is a simple overview of the most common options.
Entity | What it is | Key considerations |
Sole proprietorship | Default for a single owner who has not formed another entity | Easy to start but no personal liability protection |
Partnership | Business owned by two or more people | Pass through taxes, no liability shield without an LLP |
Limited liability company | Separate legal entity with flexible tax choices | Liability shield, can elect S or C taxation |
S corporation | Corporation that is taxed as a pass-through entity | Liability shield, payroll for owners, compliance duties |
C corporation | Separate legal entity that pays corporate tax | Unlimited owners and fundraising options, but comes with more formal requirements |
Each entity type has benefits and costs. Many growing small businesses compare an LLC and an S corporation because both provide liability protection while offering different tax options.

S corp vs LLC
These are often the two most common choices for sole proprietors who are ready for a more formal business structure.
Management structure
An LLC offers flexibility. Owners can manage the business themselves or appoint managers.
An S corporation follows a more structured approach. It typically requires corporate officers, directors, regular meetings, and corporate records.While this adds paperwork, many businesses appreciate the additional structure as they grow.
Taxation structure
Both LLCs and S corporations can offer pass-through taxation.
An LLC can choose how it wants to be taxed, while an S corporation follows the IRS rules for S corporation taxation.
With an S corporation, business income generally passes directly to the owners instead of being taxed at the corporate level.
Self employment tax
One reason many profitable businesses consider an S corporation is payroll tax treatment.
Owners who actively work in an S corporation receive a reasonable salary through payroll. Additional qualifying profits may be distributed separately and are generally not subject to self employment taxes.
By comparison, a sole proprietorship or a default LLC often pays self-employment taxes on the entire business profit.
Formal requirements
An LLC has fewer ongoing administrative requirements.
An S corporation requires more documentation, payroll administration, and corporate recordkeeping. Those extra responsibilities may be worthwhile if the tax savings outweigh the additional work.
S corp vs LLC: At a glance
Feature | S corporation | LLC |
Liability protection | Yes | Yes |
Pass-through taxation | Yes | Yes with option to elect corporate |
Owner compensation | Salary plus distributions | Owners draws or salary depending on tax election |
Self-employment taxes | On salary only | Often on all profit unless electing S |
Payroll required for active owners | Yes | Only in certain tax elections |
Governance | Board and officers | Flexible by operating agreement |
Benefits of an S corporation
An S corporation gives many growing businesses a combination of legal protection and tax flexibility.
Liability protection
Once your business becomes its own legal entity, there is generally greater separation between business obligations and your personal assets.
Potential tax savings
For businesses with consistent profits, an S corporation may reduce overall payroll tax exposure because only reasonable compensation paid as salary is subject to payroll taxes.
Every situation is different, so it is important to work with a tax professional before making the election.
Professional credibility
Many lenders, vendors, and business partners view incorporated businesses as more established.While this does not guarantee funding or opportunities, it can support future growth.
Growth opportunities
An S corporation permits up to 100 shareholders. The structure and recordkeeping make the business appear more established to lenders, partners, and clients. The added formality supports due diligence as you grow.
Example comparison
The numbers below show a simplified example of how compensation may differ. (Please keep in mind that these numbers are illustrative.)
Category | Sole prop | S corp |
|---|---|---|
Revenue | $75,000 | $75,000 |
Business expenses | $40,000 | $40,000 |
Owner salary | N/A | $25,000 |
Employer payroll taxes | N/A | $2,346.50 |
Taxable income after salary | $35,000 | $7,652.50 |
Self-employment tax | $4,945.34 | N/A |
Employee payroll tax withheld | N/A | $1,912.50 |
Total payroll-related taxes paid | $4,945.34 | $4,259 |
Actual tax savings depend on salary, business profit, state taxes, and several other factors.
S corporation owners can combine a reasonable salary with profit distributions that are not subject to employment taxes. Be sure to avoid setting the salary too low. See our guide on paying yourself as an S corporation for compliance tips.

Signs you should consider an S corporation
There is no perfect time for every business, but these are common reasons owners begin exploring S corporation status.
Your profits have become consistent.
You want liability protection.
Self employment taxes are increasing.
You plan to hire employees.
You want a more formal business structure.
You expect continued business growth.
Is an S corp right for your business?
Before making the change, think beyond the potential tax savings. An S corporation also comes with ongoing responsibilities.
Typical ongoing costs include:
Payroll processing
Employer payroll taxes
Accounting support
Tax preparation
State filing fees
Business insurance
Corporate recordkeeping
Compare these costs with your expected tax savings. For many businesses, the numbers become more favorable as profits increase.
It is also helpful to think about your long-term plans:
Business goal | Why it matters |
|---|---|
Hiring employees | Payroll systems become more important |
Bringing on owners | Ownership rules apply to S corporations |
Seeking financing | Corporate records may support due diligence |
Future growth | More formal business operations may be beneficial |
Will you seek investors
Do you anticipate a merger or acquisition
Will you add partners
An S corporation offers structure and flexibility for many small firms, but ownership and stock class limits may not fit every growth plan.
3 steps to convert from a sole proprietorship to an S corporation
Once you decide an S corporation is the right fit, the process is fairly straightforward.
Step 1: Form an LLC
Many business owners first create an LLC before making the S corporation tax election.
Typical steps include:
Choose a business name.
File formation documents with your state.
Create an operating agreement.
Apply for an Employer Identification Number.
Register for any required licenses or state taxes.
Step 2: Confirm eligibility
To qualify for S corporation taxation, your business must meet IRS requirements.
These generally include:
Domestic business entity
No more than 100 shareholders
One class of stock
Eligible shareholders only
Step 3: File IRS Form 2553
IRS Form 2553 allows an eligible business to elect S corporation tax treatment.
The form includes information such as your business name, Employer Identification Number, election date, and shareholder details.
After approval, your business will generally begin operating under S corporation tax rules on the effective date of the election.

Do I have to pay myself a salary as an S corporation owner?
Yes. If you actively work in the business, the IRS generally expects you to receive reasonable compensation through payroll.
Can I skip payroll during a slow month?
Owners who provide services should maintain compliant payroll practices. Regular payroll helps support IRS compliance.
Can an LLC become an S corporation later?
Yes. Many business owners first form an LLC and later elect S corporation taxation when business profits justify the change.
Will switching automatically reduce my taxes?
Not always. The amount of potential savings depends on your profits, salary, business expenses, and state tax rules.
Can I still take owner draws?
Once your business is taxed as an S corporation, owner compensation is generally handled through payroll and shareholder distributions rather than traditional sole proprietor draws.
