I'm a 1099 contractor — LLC or S-corp election, which actually saves tax?
Under Treasury Regulation §301.7701-3, a single-member LLC is disregarded as separate from its owner for federal income tax purposes unless it elects otherwise. In practice that means:
Why forming an LLC changes nothing on your tax bill
Under Treasury Regulation §301.7701-3, a single-member LLC is disregarded as separate from its owner for federal income tax purposes unless it elects otherwise. In practice that means:
- You file one return (Form 1040) with Schedule C — exactly like a sole proprietor.
- Your entire net profit is subject to self-employment tax: 12.4% Social Security (on earnings up to the 2026 wage base of $184,500) plus 2.9% Medicare (no cap), calculated on 92.35% of net profit.
Example: $100,000 net profit → SE tax base = $92,350 → SE tax ≈ $14,130.
What an LLC does give you is a liability shield and a door you can walk through: an LLC (but not a sole proprietorship) can file Form 2553 and elect S-corporation tax treatment without restructuring the business legally.
How the S-corp election saves money — the mechanism
As an S-corp owner-employee you must pay yourself a reasonable W-2 salary. Only the salary is subject to payroll tax (7.65% employer + 7.65% employee = 15.3% on both sides); profit you take as distributions is not subject to FICA or self-employment tax.
Same $100,000 profit with a $60,000 reasonable salary:
| Item | Default LLC (Schedule C) | S-corp election |
|---|---|---|
| Subject to SE/payroll tax | $100,000 (all profit) | $60,000 (salary only) |
| SE/FICA tax | ≈ $14,130 | $9,180 |
| Tax return | Schedule C | Form 1120-S + K-1 + W-2 |
Gross savings: roughly $4,950 — before the new costs.
The costs most people underestimate
| Cost | Typical annual range |
|---|---|
| Payroll service (Gusto/ADP, quarterly 941s, W-2) | $500–$1,500 |
| Form 1120-S preparation (more complex than Schedule C) | $1,000–$2,500 |
| State franchise/fees (e.g., CA's $800 minimum) | $0–$800+ |
| Unemployment insurance (FUTA/SUTA on your own salary) | varies |
Add a realistic $3,000–$4,500 a year in extra overhead. There's also a subtler cost: in an S-corp, your W-2 salary is not qualified business income, so your Section 199A deduction shrinks — partially offsetting the payroll-tax savings.
The rough breakeven
Folding in typical compliance costs and the QBI effect, the pattern looks like this:
| Net profit | Net effect of S-corp election |
|---|---|
| Under ~$60,000 | Usually loses money |
| ~$65,000–$90,000 | Marginal to slightly negative |
| ~$95,000–$100,000 | Approximate breakeven |
| ~$120,000 | Around $1,800 net savings |
| $150,000+ | Savings become clearly worthwhile |
These are illustrative ranges, not guarantees — your reasonable salary number and your state drive the real answer.
How to make the election
- File Form 2553 — by mail or fax only (no e-file).
- Deadline: no later than 2 months and 15 days after the start of the tax year the election should take effect — March 15 for a calendar-year filer. New entities get 2 months and 15 days from formation.
- Missed it? Rev. Proc. 2013-30 provides late-election relief if you have reasonable cause and act within 3 years and 75 days.
- Eligibility: domestic entity, 100 or fewer shareholders, one class of stock, and no nonresident-alien shareholders — an LLC can elect without filing Form 8832 first (the 2553 carries the classification).
Frequently asked questions
I'm under $60K profit but growing fast — should I elect now or wait?
Wait. Electing early burns cash on compliance while profits are too small to save anything, and once you elect, revoking and re-electing is restricted (generally a 5-year waiting period). Revisit when your trailing-12-month profit is stable above $90K–$100K.
Can I just take a tiny salary and huge distributions to maximize savings?
No — that's the single fastest way to get audited. The IRS can recharacterize distributions as wages under Rev. Rul. 74-44 and assess back payroll taxes, interest, and penalties. Courts have sided with the IRS in cases like Watson v. Commissioner (2012), where a $24,000 salary on $200,000+ of profit was thrown out.
Does the S-corp election protect me from all self-employment tax?
No — only from payroll tax on the non-salary portion. If your business income passes the Social Security wage base, the extra 2.9% Medicare still applies to salary, and income tax applies to 100% of the S-corp's profit either way (S-corps are pass-through).
