First, un-confuse the terms
This is not 'LLC versus S corp' as competing structures. Your LLC is a legal entity; S corporation is a tax status your LLC can elect. You keep the same company, the same contracts, the same name, you're choosing how the IRS taxes it: as a default pass-through (sole proprietorship or partnership rules) or under S corporation rules. The election is one form (2553); the consequences are a different tax life.
What the election changes
A default LLC's entire profit is subject to self-employment tax: 15.3% applied to 92.35% of net earnings, up to the Social Security wage base, then 2.9%+ beyond, on top of income tax. Draw patterns don't matter; profit is what's taxed. (Full picture: How to Pay Yourself From an LLC (Without Creating IRS Trouble) .)
Under S corporation rules, an owner who performs services generally receives reasonable W-2 compensation, while properly classified distributions generally are not wages subject to employment taxes. The benefit is not a flat 15.3% calculation because wage-base rules, income taxes, state treatment, benefits, and compliance costs also matter. That gap, profit minus defensible salary, is where the entire benefit lives, which is why the salary question is the strategy: S Corp Reasonable Salary: How to Actually Set the Number .
What the election costs
- Payroll, mandatory: registrations, withholding, quarterly filings, W-2s, either your hours or a service's fee ($600–$1,500/year outsourced). No payroll, no election benefits; just risk.
- A separate business tax return (1120-S), typically $800–$1,500+ prepared, versus the Schedule C that rode along with your 1040 for free-ish.
- More bookkeeping formality: a balance sheet that balances, owner basis tracking, clean separation of salary and distributions. Casual books and S corps mix badly.
- State wrinkles: some states tax S corps separately or don't fully honor the election, worth checking before, not after.
The break-even, with real numbers
There is no universal profit threshold at which an S election wins. The useful test compares profit with a defensible salary, then adds payroll, tax-return, bookkeeping, state-tax, and benefit effects. The following profiles are illustrations only:
- $50K profit: reasonable salary for the work is, say, $40K. SE-tax savings on the $10K gap ≈ $1,500. Costs (payroll + return + admin) ≈ $2,000+. Verdict: skip, revisit next year.
- $100K profit: salary $65K, distributions $35K. Savings ≈ $5,300. Costs ≈ $2,500. Verdict: worth it, netting ~$2,800/year, growing as profit grows.
- $180K profit: salary $100K, distributions $80K. Savings ≈ $11–12K. Costs unchanged. Verdict: clearly worth it, this is the profile the strategy was built for.
Notice what drives the answer: not revenue, profit, and not profit alone, but profit relative to what your work is honestly worth. A $150K-profit business where a defensible salary is $130K saves little. A $150K-profit business running on crews and systems, where the owner's replacement cost is $70K, saves a lot. Service businesses with real staff hit the second profile much more often than solo operators do.
Timing and mechanics
The election (Form 2553) is generally due within 2 months and 15 days of the start of the tax year you want it effective, though late-election relief is routinely available when you have a reasonable cause story. The cleaner play is deciding in Q4 for January 1: payroll starts fresh with the year, books restructure once, and there's no mid-year hybrid period to account for. This is a decision to run with someone who sees your actual numbers, profit trend, owner hours, state rules, not a forum's.
When to stay a default LLC
- Profit too close to a defensible salary to produce meaningful net benefit after payroll, return, bookkeeping, and state-level costs
- Heavy reinvestment years, profit you're plowing back still gets taxed either way, but the election's fixed costs hurt more when cash is tight
- Owners unwilling to run real payroll and keep formal books, a half-adopted S corp (election filed, no payroll) is the worst of all positions: audit exposure with zero savings
- Certain states where the local tax treatment erases the federal benefit
Frequently asked questions
Can I undo the election if I regret it?
Revocation is possible but sticky, generally locking you out of re-electing for five years. Treat it as a durable decision made on a trend, not one great quarter.
Does the S corp protect me legally?
No change, liability protection comes from the LLC itself, not the tax status. The election is purely a tax decision.
Who should run this analysis for me?
Whoever can see twelve months of real books. We run the break-even for bookkeeping clients as part of tax work, and if the answer is 'elect,' the payroll and return come from the same desk. Business Tax Preparation Services
