How much does an S Corp election actually save? (with worked examples)

Every CPA and TikTok tax guru tells you "elect S Corp and save thousands." Few of them show you the actual math. Even fewer mention that below a certain profit level, the election can lose you money once you factor in the new costs.

This is the math, with three real worked examples and the threshold where the savings flip negative.

Where the savings come from

Self-employment tax is a flat 15.3% on the first $168,600 of net earnings (2026 wage base — Social Security 12.4% + Medicare 2.9%). Above that, only the 2.9% Medicare portion continues, plus an extra 0.9% on earnings over $200k single / $250k joint.

When you operate as a sole proprietor, single-member LLC, or partnership, every dollar of profit hits SE tax. A $120,000 profit owes roughly $16,950 in SE tax before you even start federal income tax.

When you elect S Corp status, your business income splits into two buckets:

• W-2 wages (your "reasonable salary") — subject to the 15.3% payroll tax
• Distributions (everything left over) — subject to income tax but not payroll tax

The savings = 15.3% × (profit − reasonable salary).

That's the whole engine. Everything else is plumbing.

What "reasonable salary" actually means

The IRS doesn't publish a formula. They've published audit guidelines saying the salary should reflect what a third party would pay someone to do your work — same role, same hours, same industry, same region. In practice, most CPAs use one of two heuristics:

• 40–60% of profit as W-2 wages, with the remainder as distributions
• Bureau of Labor Statistics median wage for your job code, scaled to your hours

Both are defensible. Both leave room for IRS challenge. The single biggest red flag is paying yourself a tiny salary ($20k) on a high-profit business ($300k); the IRS reclassifies all of that as wages and you owe back-payroll-tax plus penalties.

A safe rule of thumb: pay yourself what you'd grudgingly accept if a competitor poached you for the same job. Document the basis (BLS data, comparable job postings, your actual hours).

Three worked examples

These use 2026 SE tax thresholds, ignore state income tax, and assume the owner is a single filer with no other income. Numbers are rounded to the nearest hundred.

Example 1: Solo consultant, $80k profit

A solo IT consultant nets $80,000 after expenses. CPA recommends a 50/50 wage split.

But there are new costs:

• Payroll software (Gusto, OnPay): ~$50/mo = $600/yr
• Tax prep for Form 1120-S: ~$500–$1,500/yr (vs. Schedule C included in personal return)
• FileMyScorp election filing: $49–$99 one-time

Net first-year benefit: roughly $3,000–$4,000. Recurring annual benefit: roughly $4,000.

S Corp wins, but not by as much as the gross savings number suggests.

Example 2: Two-partner agency, $200k profit, 50/50 split

A husband-wife marketing agency nets $200,000 split equally. They pay themselves $50,000 each in W-2 wages.

Less:

• Payroll software: $600/yr
• Form 1120-S preparation: $1,000–$2,000/yr
• One-time election filing: $99

Net annual benefit: about $11,000. This is the sweet spot for S Corp election — high enough profit that the savings dwarf the added complexity, owners with clean facts, and a defensible reasonable-salary calc.

Example 3: Side hustle, $35k profit

A part-time graphic designer nets $35,000 from freelance work. CPA recommends $20k salary, $15k distributions.

Less:

• Payroll software: $600/yr
• Form 1120-S prep: $1,000/yr (for a small S Corp)

Net result: roughly break-even or slightly negative. At this profit level, the election usually doesn't make sense unless the designer expects profit to grow significantly next year.

The profit threshold where it stops being worth it

Combining the math: an S Corp election typically pays for itself once net profit clears roughly $50,000–$60,000 per year, assuming:

• The owner is willing to run payroll
• A CPA or tax software handles Form 1120-S
• The reasonable-salary split holds up under IRS scrutiny

Below that, the recurring costs (payroll + 1120-S prep) eat the SE tax savings. Above $100k, the election almost always wins decisively.

If you're at $40k–$60k, talk to a CPA before electing. If you're at $80k+, the question isn't whether to elect — it's when (now, vs. wait until next year).

Things this math doesn't include

A few real-world wrinkles:

• State income tax. Some states (CA, NY, NJ, IL) tax S Corp profits at the entity level. Your federal savings can be partly clawed back. Check your state.
• QBI deduction (Section 199A). Both sole props and S Corps can claim it on qualified income. The math is roughly neutral between the two.
• Solo 401(k) contributions. S Corps can contribute the employer share based on W-2 wages, sometimes hitting a higher contribution ceiling than sole props. Niche but real.
• Health insurance, HSA, retirement plans. S Corps have their own quirks (>2% shareholders pay tax on health premiums; HRAs work differently). Not a deal-breaker, but a thing to handle.
• Audit risk. S Corp returns are audited at a slightly higher rate than sole props, mostly because of the reasonable-salary trap. Pay yourself fairly, document why, and you're fine.

When the election almost certainly wins

If all of these are true, elect S Corp. Today, if you can:

1. Net profit consistently above $70k
2. You're the only employee or have just a few co-owners
3. You can pay yourself a defensible W-2 salary (40–60% of profit, supported by BLS data)
4. You don't mind running payroll once a quarter
5. Your CPA already prepares business returns

When to wait

Skip or delay if:

• You're under $50k profit and growth is slow
• You have non-resident-alien co-owners (disqualifies the election)
• You're planning to raise outside investment soon (S Corp's one-class-of-stock rule limits VC structures)
• You have a complex C Corp history (NOLs, accumulated E&P) that needs a tax-attorney review first

How to actually do it

Once you've decided, the mechanics are simple:

1. Confirm eligibility — try our eligibility checker to see which deadline window applies
2. File Form 2553 — on time (within 2 mo 15 days) or late under Rev. Proc. 2013-30 (up to 3 years 75 days late)
3. Set up payroll — Gusto/OnPay before your first paycheck
4. Run a year-end W-2 for yourself
5. File Form 1120-S annually instead of Schedule C

We handle step 2 in about ten minutes for $49–$99. Steps 1, 3, 4, and 5 are on you (or your CPA).
