Stop paying 15.3% on every dollar.
Elect S-corp.
If you net more than $40K as a sole prop or single-member LLC, you're handing the IRS thousands every year in self-employment tax that an S-corp election would erase.
The 60-second pitch
A sole prop or single-member LLC pays 15.3% self-employment tax on every dollar of net profit — Social Security (12.4%) + Medicare (2.9%). An S-corp doesn't.
Instead, you pay yourself a "reasonable" W-2 salary (subject to FICA), and the rest of the profit flows through as a distribution — completely exempt from SE/FICA tax. On a $150K-profit business, splitting $80K W-2 + $70K distribution saves you the 15.3% on that $70K — about $10,710 a year, every year, for as long as the business runs.
It's not a loophole. It's how every law firm, dental practice, and consulting LLC in the country actually pays its owners. The only catch: you have to file Form 2553 with the IRS by March 15 of the year you want it to kick in (or within 75 days of forming the entity).
The $10,710 difference
Jordan runs a one-person marketing consulting LLC. Last year she netted $150,000 in profit. As a single-member LLC taxed as a sole prop, every dollar of that profit is subject to self-employment tax.
| Sole prop · current setup | |
| Net profit (Schedule C) | $150,000 |
| SE tax (15.3% × 92.35%) | −$21,194 |
| S-corp · after election | |
| Reasonable W-2 wage | $80,000 |
| FICA on wage (15.3%) | −$12,240 |
| Distribution (no SE/FICA) | $70,000 |
| SE/FICA on distribution | $0 |
The step-by-step checklist
- Confirm you clear the threshold. The S-corp math only works once payroll-admin costs (~$500–$1,200/yr for payroll service + extra accounting) are smaller than the SE-tax saved. Generally $40K+ of net SE income is the floor; the sweet spot is $80K–$300K.
- Form (or convert to) an LLC. You can elect S-corp status from an LLC — no need to actually incorporate. Most tax preparers prefer LLC + S-corp election over a corporation for state-level flexibility.
- File Form 2553 with the IRS. Deadline: no more than 2 months and 15 days after the start of the tax year (so
March 15for a calendar-year business wanting current-year treatment), or within 75 days of forming the entity. Late elections can sometimes be cured under Rev. Proc. 2013-30. - Set a reasonable wage. Use comp surveys (BLS, Glassdoor, RCReports). Document the analysis. The IRS wants to see that your wage reflects what you'd pay a non-owner employee doing the same job — not the legal minimum.
- Run actual payroll. Quarterly 941 filings, W-2 at year-end, withholding of federal/state income tax + FICA. Use Gusto, ADP, QuickBooks Payroll, or similar — don't try to hand-roll this.
- Pay yourself distributions separately. Transfer from business → personal as "Owner Distribution" — NOT through payroll, NOT 1099. Keep a clean separation in the books.
- File Form 1120-S annually by March 15 (one month earlier than Schedule C). Issue yourself a K-1. Distributions show up on K-1 line 16D, wages on the W-2.
- Re-evaluate annually. If profit drops or you take fewer distributions, the math may flip. If profit climbs, increase the wage to stay defensible.
The law — cite this in your file
- IRC §1361 S-corporation definition. Defines who can elect S status — <100 shareholders, all individuals/estates/certain trusts, one class of stock, US-resident shareholders.
- IRC §1362 Election; revocation; termination. The mechanics of making and revoking the S election. Form 2553 lives here.
- IRC §1366 Pass-through of items to shareholders. Profit, loss, deductions all flow through to the shareholder's 1040 — no entity-level federal income tax.
- IRC §1372 2% shareholder fringe benefit rules. Self-employed health insurance for >2% shareholders is deductible above-the-line on the 1040 — but goes through payroll as wages.
- Rev. Rul. 74-44 The reasonable-compensation case. The IRS recharacterized "distributions" to S-corp owners as wages where no salary was paid. This is the foundation of every reasonable-comp audit.
- Rev. Proc. 2013-30 Simplified late-election relief. If you missed the Form 2553 deadline, this is how you fix it — usually within 3 years and 75 days.
- Watson v. Comm'r (8th Cir. 2012) The defining reasonable-comp case. The owner paid himself $24K wage on $200K+ of distributions; court bumped wage to $91K. Read this before setting your salary low.
Audit risk flags
- Wage too low relative to distributions. The single biggest S-corp audit trigger. If your W-2 is <30% of total comp on a profitable business, prepare to defend it with a wage study.
- Zero W-2, all distribution. You will lose this audit. Owners who actively work in the business must take a salary.
- No documentation of how you set the wage. Print BLS occupational wage data, RCReports analysis, or comp-survey results before you set the salary — not after the IRS notice.
- Distributions to non-pro-rata owners. If there are multiple shareholders and distributions don't track ownership %, you can terminate the S election by creating a deemed second class of stock.
- Health-insurance reporting mistakes. >2% shareholder health insurance must be added to W-2 box 1 (not boxes 3/5). Get this wrong and you lose the above-the-line deduction.
- Missing payroll filings. Failure to file 941s and W-2s triggers Trust Fund Recovery Penalty — personal liability for unpaid payroll taxes.
When not to elect S-corp
- Net profit under $40K. The payroll admin cost ($500–$1,200/yr) plus extra accounting eats the savings. Stay sole prop.
- You want to keep cash inside the business long-term. S-corp profits are taxed to you whether distributed or not. A C-corp may actually be better if you're stockpiling retained earnings.
- You're planning to take big losses. Sole-prop losses offset other income on the 1040 without basis limits the same way. S-corp losses are limited by stock + debt basis (IRC §1366(d)).
- You have foreign or trust shareholders. S-corp eligibility is strict — non-resident aliens and most trusts disqualify the election.
- You're in a state that taxes S-corps separately (CA's 1.5% S-corp franchise tax, NYC's 8.85% UBT, TN's franchise/excise tax). Run the all-in math, not just the federal.
- You hate paperwork. S-corp adds quarterly payroll, an 1120-S return, board minutes, and the constant pressure to defend your wage. Some people take the SE tax just to be left alone.
