Owner compensation — S-Corp election, reasonable salary, payroll

Status: research-only. Nothing here is legal or tax advice. Before filing Form 2553, setting a salary, or hiring a payroll provider, consult a CPA. Reasonable-compensation determinations are fact-specific and IRS-audit-defensible analysis is squarely in CPA territory.

TL;DR

An LLC can elect S-Corp tax treatment by filing Form 2553. Once effective, the owner becomes a shareholder-employee and the IRS requires them to be paid reasonable compensation as W-2 wages before any non-wage distributions. FICA (Social Security + Medicare, 15.3% employer+employee) applies to wages only — distributions are not subject to FICA or self-employment tax. That's where the S-Corp savings come from. The cost: running real payroll (~$40–$150/month), filing Form 1120-S + K-1 instead of Schedule C (higher tax-prep), and defending the "reasonable" salary figure if audited. Deadlines matter: Form 2553 must be filed within 2 months and 15 days of the start of the tax year the election is to take effect, or anytime during the preceding year. Late-election relief exists via Rev. Proc. 2013-30 if eligibility conditions are met.

Facts (with citations)

Form 2553 — the S-Corp election

• Form 2553 is the election form by a small business corporation (or LLC electing S-Corp treatment). Must be signed by all shareholders. [IRS — Form 2553: 1]
• Filing deadline: no later than 2 months and 15 days after the start of the tax year the election is to take effect. For a calendar-year entity, that means by March 15 of the year you want it effective. You can also file any time in the preceding tax year to elect for the next year. [IRS — S corporations: 2, Form 2553 instructions: 1]
• Late-election relief is available under Rev. Proc. 2013-30 if the entity meets eligibility requirements, typically requiring that the entity otherwise qualified, intended to be an S-Corp, and files within 3 years and 75 days of the intended effective date. Reasonable-cause statement required. Have your CPA handle this.
• Eligibility requirements (recap from entity-structure.md): domestic entity, ≤100 shareholders (all US citizens/residents — no entity shareholders except certain trusts/estates), one class of stock, not an ineligible corporation (certain financial institutions, insurance companies, domestic international sales corporations). [2]

Reasonable-compensation doctrine

• IRS explicit position: "S corporations must pay reasonable compensation to a shareholder-employee in return for services that the employee provides to the corporation before non-wage distributions may be made to the shareholder-employee." [IRS — S corporation compensation and medical insurance issues: 3]
• IRS has explicit authority to reclassify non-wage distributions as wages subject to employment taxes if it finds compensation unreasonably low. [3]
• The instructions to Form 1120-S state: "Distributions and other payments by an S corporation to a corporate officer must be treated as wages to the extent the amounts are reasonable compensation for services rendered to the corporation." [3]
• Court support cited by the IRS: Joly v. Commissioner (T.C. Memo 1998-361, aff'd 211 F.3d 1269 (6th Cir. 2000)); Veterinary Surgical Consultants, P.C. v. Commissioner (reclassification of payments to shareholders as wage expense). [3]
• There is no statutory safe-harbor figure. Reasonable compensation is determined by facts and circumstances — industry comparables, hours worked, training, duties, geographic factors. The "60/40" rule and similar heuristics are NOT official IRS safe harbors; they are CPA-community rules of thumb. [3]

Self-employment tax and FICA mechanics

• Self-employment tax (Schedule SE, for disregarded-entity LLCs) = 15.3% on net self-employment income up to the Social Security wage base, then 2.9% above (Medicare only) + 0.9% additional Medicare on earnings above $200k single / $250k joint.
• FICA on W-2 wages = same rates, split between "employer" and "employee" but paid in full by the shareholder-employee when they are also the owner (the employer portion is a deductible business expense to the S-Corp).
• Distributions from an S-Corp to a shareholder are not subject to SE tax or FICA. This is the tax-saving lever.

Estimated taxes

• S-Corp shareholders (like sole proprietors and partners) generally use Form 1040-ES to pay federal estimated taxes quarterly on pass-through income. [IRS Estimated taxes: 4]
• Quarterly due dates (federal, for calendar-year individuals): April 15, June 15, September 15, January 15 (of the following year). State estimates have their own schedules.

Options compared — payroll providers for a solo S-Corp owner

All figures are representative public pricing as of research date and should be verified at purchase time on the provider's pricing page.

Budget heuristic for a solo S-Corp owner: expect $40–$100/month for payroll service. Annualized: $480–$1,200/year — this is the single biggest recurring cost added by the S-Corp election.

Other S-Corp costs to factor into a breakeven analysis

• Additional tax-prep fee. Form 1120-S (S-Corp return) + K-1 to owner — typically $500–$1,500 more per year than a Schedule C on a personal return.
• State employer account setup + annual. Usually one-time small fees; ongoing filings handled by payroll provider.
• State unemployment insurance (SUTA). New-employer rate varies by state, typically 2–5% on first ~$7k–$50k of wages.
• Workers' comp insurance — most states require it once you have an employee (including an S-Corp owner W-2), with sole-proprietor and sole-shareholder exemptions varying by state. Confirm with the state insurance bureau.

The "too-low salary" audit risk

IRS red flags that can trigger a reasonable-comp adjustment: - Large distributions with zero or near-zero W-2 wages. - W-2 wages set just below Social Security wage base when the business clearly earns far more. - Inconsistency between the owner's stated role and a low stated compensation.

Audit defense typically requires: - Industry comparables (BLS, Salary.com, PayScale, RCReports) for the owner's role + geography + firm size. - Time allocation — what percent of the owner's time is "services rendered" (W-2 wage) vs. passive ownership (distribution)? - Contemporaneous documentation — written salary determination dated before the year starts.

RCReports (~$140–$300/year) is a CPA-oriented tool that produces a defensible reasonable-compensation report. Many CPAs include this in S-Corp engagements.

Breakeven sketch (NOT a recommendation)

A rough mental model the CPA can verify with real numbers:

• Additional recurring cost of S-Corp: ~$500 payroll/year + ~$1,000 tax-prep uplift + RCReports ~$200 = ~$1,700/year.
• FICA saved per dollar of distribution (vs. SE-taxed income): 15.3% on income below the Social Security wage base; 2.9% above.
• Breakeven in FICA savings alone: if the "distribution" portion (above reasonable salary) is ~$30,000, FICA saved ≈ $4,590. Net benefit ≈ $2,890.
• Net income ~$70k–$100k with reasonable-salary $40k–$60k range is where the math starts being obviously positive. This depends heavily on actual numbers, state, and comparables — CPA territory.

Jurisdiction flags

• State conformance to federal S-Corp election. Most states treat an S-Corp as pass-through at the state level too, but not all. New York requires a separate state-level S-Corp election. California taxes S-Corps at 1.5% of net income even as pass-through. Confirm with your CPA for the operating state.
• State payroll. Every state with income tax has an employer withholding account; most have SUTA. Payroll provider handles most of this, but someone has to register the accounts initially — some states register automatically when you form an LLC with employees; most do not.
• Health-insurance S-Corp wrinkle. Premiums paid by the S-Corp for a >2% shareholder-employee must be reported as W-2 wages (Box 1) but are deductible as self-employed health insurance on the shareholder's 1040. This is a frequent audit area — CPA territory. [3]

Timing / deadlines

• Form 2553 deadline: 2 months + 15 days after start of the tax year the election is to take effect (March 15 for calendar-year). [1]
• Late-election relief window: within 3 years + 75 days of the intended effective date, with reasonable-cause statement (Rev. Proc. 2013-30). [1]
• Quarterly federal estimates (Form 1040-ES): April 15, June 15, September 15, January 15. [4]
• Payroll filings: Form 941 quarterly (end of month after quarter close); Form 940 annually (January 31); W-2/W-3 to SSA by January 31. Payroll provider handles.

Questions for your CPA

1. Breakeven analysis. At my projected year-1 and year-2 revenue, does the S-Corp election net positive after payroll + tax-prep uplift? Can you produce a memo with specific numbers?
2. Reasonable salary. Based on my role (sole founder / CTO of a pre-revenue options-trading SaaS) and geographic area, what's a defensible reasonable-compensation range? Will you produce an RCReports or equivalent analysis I can point to if audited?
3. Election timing. Should I file Form 2553 for the current tax year, or wait for next January 1 and file by March 15 of that year? Does forming mid-year change the answer?
4. Late-election relief. If I miss the 2553 deadline, can you handle the Rev. Proc. 2013-30 reasonable-cause filing?
5. Payroll provider recommendation. Do you have a preferred payroll provider your other S-Corp clients use successfully? Any integration cost with your tax-prep?
6. Health insurance. I pay my own health-insurance premium now. Post-S-Corp, how should I structure it (S-Corp-paid + W-2 add-back + SEHI deduction)?
7. Home-office deduction. Can I structure an accountable-plan reimbursement from the S-Corp to me (the shareholder) for home-office use? What records do I need to keep?
8. Estimated taxes. Who computes my quarterly estimated-tax vouchers — you, or do I self-compute with 1040-ES? What's the penalty-avoidance safe harbor in my state?

Questions for your business-formation attorney

1. Do I need a shareholder-employee employment agreement between me and the S-Corp? What clauses should it have (compensation, IP assignment, confidentiality, at-will status)?
2. Any state-level corporate-resolution requirements for setting the initial compensation (e.g., board resolution even for a single-member LLC taxed as S-Corp)?
