LLC to S-Corp Conversion: When It Saves You Money

The tax strategy that can save you thousands.

Key Takeaway

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

Good Candidate

  • Net profit consistently above $80,000
  • Stable income (not wildly variable)
  • Willing to run payroll
  • Have a good CPA to manage it

Not Ready Yet

  • Net profit below $60,000
  • First year in business
  • Income highly variable
  • Don't want additional complexity

How to Elect S-Corp Status

  1. File Form 2553 with the IRS
  2. Deadline: Within 75 days of start of tax year (or within 75 days of forming LLC)
  3. Late election possible with reasonable cause
  4. Work with a CPA — this is not DIY territory

Ongoing Requirements

  • Run payroll (quarterly deposits, W-2 at year-end)
  • File S-Corp tax return (Form 1120-S)
  • Issue K-1 to yourself
  • Maintain corporate formalities
  • Reasonable salary documentation

S-Corp Savings Calculator

Net profit: $120,000 As LLC (no S-Corp): SE tax (15.3%): $18,360 As S-Corp: Salary: $60,000 Payroll tax: $9,180 Distribution: $60,000 SE tax on distribution: $0 Total payroll tax: $9,180 Gross savings: $18,360 - $9,180 = $9,180 S-Corp costs: ~$3,000/year Net savings: $6,180/year At $120K profit, S-Corp is clearly worth it. At $60K profit, savings are ~$2,500 — marginal after costs. At $150K+ profit, savings exceed $10,000/year.

Common Mistakes

Converting too early

→ Wait until profit consistently exceeds $80K. Below that, the costs may exceed savings.

Setting salary too low

→ The IRS will reclassify distributions as salary if your salary is unreasonably low. Pay yourself fairly.

DIY without a CPA

→ S-Corp tax returns are complex. The cost of a CPA is worth avoiding mistakes.

Forgetting payroll deposits

→ Payroll taxes are due quarterly (or more often). Late deposits = penalties.

Missing the election deadline

→ File Form 2553 within 75 days of year start. Late elections are possible but complicated.

Action Step

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.

Pro Tip

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.
