# S-Corp Election: When It Pays Off (and When It Doesn't)

Last updated: 26 April 2026

S-corp election typically pays off once net business income exceeds approximately $80,000 per year. By splitting income between reasonable W-2 wages (FICA-bearing) and K-1 distributions (no FICA), you save 15.3% of self-employment tax on the distribution portion. Net annual savings after payroll/CPA costs: around $6,000 at $150k profit, $15k+ at $300k. File Form 2553 within 75 days of qualifying.

The S-corp election is the single most powerful federal tax tool available to profitable owner-managed US businesses. Under-used by businesses that would benefit, mis-used by those who shouldn't elect, and abused by those who don't pay reasonable compensation.

This guide explains exactly when S-corp election pays off, when it doesn't, and how to make it work.

## What S-corp election does

An S-corp is a federal tax classification, not a separate entity type. Any LLC, sole prop or corporation can elect S-corp treatment by filing **Form 2553** with the IRS (within 75 days of formation or 75 days into the tax year you want it to start).

Once elected:

- The entity files Form 1120-S (annual return)
- The entity itself pays no federal income tax (pass-through)
- Owner-employees take a "reasonable compensation" W-2 wage subject to FICA (15.3% combined employee + employer)
- Profit above the W-2 wage flows as K-1 distribution **NOT subject to FICA**

The federal income tax on both W-2 wages and K-1 distributions is the same — they hit the personal 1040. The savings are purely on the FICA / self-employment tax side.

## Eligibility — who can elect

Strict eligibility tests for S-corp:

1. **US-only individual shareholders** (or specific trusts/estates) — no foreign owners, no entity owners
2. **Maximum 100 shareholders**
3. **Single class of stock** (voting differences allowed; economic differences not)
4. **Domestic entity** (US corporation or LLC)
5. **Not an ineligible business** (banking, insurance, IC-DISC, etc.)

If you have foreign co-founders or investors, you cannot elect S-corp. C-corp is the only option.

## The break-even point

The savings from S-corp scale with profit, but the ongoing cost (payroll service, additional CPA fees) is roughly fixed at $1,500–$3,000 per year. Below a certain profit level, the savings don't outweigh the cost.

| Net profit | Approximate FICA savings | Net benefit after costs |
|-----------|--------------------------|-------------------------|
| $50,000 | ~$4,000 | $1,000–$2,500 (marginal) |
| $80,000 | ~$5,500 | $3,000–$4,000 (worth it) |
| $150,000 | ~$9,000 | $6,000–$7,500 (clear win) |
| $300,000 | ~$18,000 | $15,000+ (no-brainer) |
| $500,000 | ~$22,000 (capped at SS base) | $19,000+ |

Below $50k–$80k, the math is tight. Above $80k, S-corp election almost always pays.

## Worked example: $200,000 net profit

### As sole proprietor / SMLLC (default)

| Item | Amount |
|------|--------|
| Net SE income | $200,000 |
| SE tax base ($200k × 0.9235) | $184,700 |
| Social Security 12.4% × $168,600 (2024 cap) | $20,906 |
| Medicare 2.9% × $184,700 | $5,356 |
| **SE tax** | **$26,262** |
| Plus federal income tax (~24% bracket effective) | ~$36,000 |
| **Federal total** | **~$62,262** |

### As S-corp ($100k W-2 wage + $100k K-1)

| Item | Amount |
|------|--------|
| W-2 wage | $100,000 |
| FICA (employee + employer) | $15,300 |
| K-1 distribution | $100,000 |
| FICA on K-1 | $0 |
| Federal income tax on $200k total | ~$36,000 |
| **Federal total** | **~$51,300** |
| **Savings vs sole prop** | **~$10,962** |

Less ~$2,000 additional payroll/CPA cost → **net annual savings ~$9,000**.

## Reasonable compensation — the audit risk

The IRS requires shareholder-employees to take reasonable W-2 wages — what someone would be paid for the same role at arm's length. Take too little and the IRS reclassifies K-1 distribution as wages, charges back FICA + interest + penalties.

How to determine reasonable comp:

1. **Industry benchmarks** — RCReports, Salary.com, BLS data
2. **Time spent** — what % of revenue comes from your direct labor vs. capital, employees, IP
3. **Comparable position** — what would a similar role pay in your market?
4. **Documented analysis** — keep evidence of how you set the wage

For a typical solo consultancy:

- $200k revenue, all from owner's labor → reasonable W-2 ~$120k–$150k (high)
- $200k revenue, partly from team's labor → reasonable W-2 ~$80k–$100k
- $1m revenue, mostly from products/IP/team → reasonable W-2 ~$150k–$250k (moderate)

Don't take $20k W-2 on $200k profit. That's a guaranteed audit issue.

## State complications

S-corp treatment is a federal election. States generally follow but with key exceptions:

- **California**: 1.5% S-corp tax (minimum $800), payroll requirements, separate state filing
- **New York**: separate state S-corp election required
- **New Hampshire / Tennessee**: don't recognize federal S-corp election for state income tax
- **Texas / Florida / Wyoming**: no state income tax — S-corp federal savings are pure win

Always check state-level treatment before electing. AccountsOS covers federal at launch; for state-specific S-corp planning, work with a state CPA.

## Filing Form 2553

The mechanics:

1. **Be eligible** (US individuals only, 100 max shareholders, single class of stock)
2. **File Form 2553** within 75 days of formation OR 75 days into the tax year for which you want S-corp status
3. **All shareholders sign** (and consent to election)
4. **IRS confirms** within ~60 days
5. **Set up payroll** before paying yourself — Gusto, Rippling, ADP, AccountsOS payroll
6. **Issue W-2** by 31 January following year-end

If you miss the 75-day window, Rev. Proc. 2013-30 allows a "late S election" with reasonable cause for up to 3 years and 75 days. This is widely used in practice — your CPA can file a late election with explanation.

## When NOT to elect S-corp

S-corp is wrong if:

- **You have foreign owners or entity owners** (not allowed at all)
- **You're raising VC** (need C-corp for preferred stock + QSBS)
- **You're below ~$80k profit** (savings don't outweigh cost)
- **You have multiple classes of stock planned** (single-class rule)
- **You have a complicated capital structure already** (preferred + common, profits interests, etc.)
- **Your state hits S-corp with extra tax** (California, for example)
- **You already have a C-corp with built-in gains** (can be triggered by S election)

## Common mistakes

- **Forgetting reasonable comp** — the IRS audits this aggressively
- **Missing the 75-day deadline** — late election is possible but messier
- **Not setting up payroll** — paying yourself "distributions" without W-2 in S-corp is a red flag
- **Treating S-corp as same as LLC** — quarterly 941 payroll filings, W-2, payroll deposits all required
- **Forgetting state-level rules** — California's $800 minimum + 1.5% S-corp tax catches many
- **Letting basis go untracked** — distributions in excess of basis are taxable; you need to know your basis
