LLC to S-Corp Conversion: When It Saves You Money
The tax strategy that can save you thousands.
S-Corp election lets you split income into salary (subject to self-employment tax) and distributions (not subject to SE tax). At around $80-100K+ net profit, the SE tax savings typically exceed the extra costs of running an S-Corp. Below that, it's often not worth it.
The Self-Employment Tax Problem
As a sole proprietor or single-member LLC, you pay self-employment tax (Social Security + Medicare) on all net profit.
Self-employment tax: 15.3% (12.4% Social Security + 2.9% Medicare) On $100,000 net profit: SE tax: $14,130 That's on top of income tax.
How S-Corp Changes This
With S-Corp election, you split your income:
SAME $100,000 PROFIT: S-Corp structure: Salary to yourself: $50,000 (subject to payroll tax) Distribution: $50,000 (NOT subject to SE tax) Payroll tax on salary: $7,650 Tax on distribution: $0 (for SE purposes) SAVINGS: $14,130 - $7,650 = $6,480/year
The Reasonable Salary Requirement
The IRS requires you pay yourself a "reasonable salary" — what you'd pay someone else to do your job.
What's Reasonable?
- Research similar roles in your area
- Consider your hours, skills, responsibilities
- Document your reasoning
General Guidelines
$80K profit: ~$45-50K salary reasonable $120K profit: ~$55-65K salary reasonable $150K profit: ~$65-80K salary reasonable $200K profit: ~$80-100K salary reasonable Rule of thumb: 50-60% as salary is often defensible. Too low = IRS audit risk.
The Break-Even Point
S-Corp has costs:
- Payroll processing: $500-1,500/year
- Additional accounting: $500-2,000/year
- S-Corp tax return: $500-1,500/year
- Registered agent (if required): $100-300/year
Total additional cost: $1,500-4,000/year
S-Corp makes sense when SE tax savings exceed these costs.
When to Convert

Common Mistakes
→ Wait until profit consistently exceeds $80K. Below that, the costs may exceed savings.
→ The IRS will reclassify distributions as salary if your salary is unreasonably low. Pay yourself fairly.
→ S-Corp tax returns are complex. The cost of a CPA is worth avoiding mistakes.
→ Payroll taxes are due quarterly (or more often). Late deposits = penalties.
→ File Form 2553 within 75 days of year start. Late elections are possible but complicated.
Calculate your net profit for the past 12 months. If it's consistently above $80K, schedule a consultation with a CPA about S-Corp election.

Your CPA can run S-Corp projections before you commit. Ask them to calculate your specific savings based on your actual numbers.
Frequently Asked Questions
Can I convert mid-year?
S-Corp election is typically effective at the start of a tax year. Mid-year conversions are complex.
What if my income drops after converting?
You can revoke S-Corp status, but there's a 5-year waiting period to re-elect. Plan carefully.
Do I need to form a new entity?
No. An LLC can elect S-Corp tax treatment without changing the legal entity. You're still an LLC.
What about state taxes?
Some states have additional S-Corp taxes or don't recognize the election. Your CPA should advise on state implications.
