If you’re asking “s corp vs llc which is better for taxes,” the honest answer is: it depends on your net profit, state fees, and how much you can pay yourself a reasonable salary. For most solo service businesses earning between $75,000 and $300,000 in net profit, an LLC taxed as an S corp usually beats a default LLC because it cuts self-employment tax on distributions. But below about $60,000 profit, the payroll and admin costs often erase savings, and in high-fee states like California, the break-even pushes higher. Below, I’ll show real-numbered models and a break-even checklist I use with clients.
Federal Pass-Through Basics That Most Guides Oversimplify
Both a default LLC and an LLC with an S corp election are pass-through entities at the federal level. The IRS does not tax the entity itself; profits flow to your personal return. The key difference is how those profits are characterized. A default single-member LLC reports all net earnings as self-employment income subject to the 15.3% SE tax (12.4% Social Security + 2.9% Medicare).
An S corp election lets you split income into two buckets: a salary (subject to payroll taxes) and distributions (not subject to SE tax). This is not a loophole; it’s built into Subchapter S. But the salary must be “reasonable” for your role, a point the IRS explicitly scrutinizes. I’ve seen clients try to pay themselves $30,000 on $400,000 profit and trigger audits.
The thing nobody tells you: the 20% qualified business income (QBI) deduction under Section 199A interacts differently. For an LLC, all net profit is QBI. For an S corp, only distributions count as QBI; the salary is wages, excluded. If your income is under the threshold ($236,100 single, $472,200 joint for 2024), this rarely hurts, but it’s a nuance competitors miss.
The S Corp Salary vs Distribution Split
When you elect S corp, you become an employee of your own company. You must run payroll and file Form 941 quarterly, plus a year-end W-2. The remaining profit after salary can be taken as distributions, avoiding the 15.3% SE tax. However, the Social Security wage base cap ($168,600 for 2024) limits how much SE tax you save at high incomes.
How to Set a Defensible Reasonable Salary
Reasonable salary is not arbitrary. The IRS looks at job duties, comparable local wages, and company revenue. I use Bureau of Labor Statistics occupational data plus a simple rule: salary should cover at least what you’d pay a replacement for your core revenue-generating work. Tools like the RC Report or a local payroll provider’s benchmark can document this.
When I first helped a freelance consultant elect S corp status in 2019, I set salary at 60% of profit. That held up fine. But a different client who set salary at 20% got a CP2000 notice three years later. The fix cost $4,200 in back payroll taxes plus penalties. Process what can go wrong: underpricing salary is the #1 S corp failure.
Real-Number Models: $75K, $150K, $300K Profit
To move beyond generic claims, I built three models using a sole owner in a zero-state-income-tax state (Texas) and assumed $1,800/year for payroll service (e.g., Gusto) and $500 for S corp tax prep (Form 1120-S). These numbers reflect what I see running books for consultants. You can plug your own figures into our S-Corp vs LLC Tax Comparison Calculator to validate.
Base Assumptions for the Models
- Federal self-employment tax rate: 15.3% up to Social Security cap ($168,600 for 2024) then 2.9% Medicare only on excess.
- Effective federal income tax rate (including pass-through 20% QBI deduction impact): roughly 22% marginal for these profit levels, used for illustration.
- S corp payroll tax: 15.3% on salary (employer+employee split, but total cost to owner same as SE).
- Admin cost: $2,300 total for payroll + S corp return.
- Social Security cap considered; Medicare surtax of 0.9% on wages over $200k ignored for simplicity but noted later.
Scenario 1: $75,000 Net Profit
Default LLC: All $75k is SE income. SE tax = $11,475 (15.3% of 92.35% of $75k). Income tax approx $7,500. Total tax + no admin = ~$18,975.
S corp: Reasonable salary set at $50k, distributions $25k. Payroll tax on salary = $7,650. SE tax on distributions = $0. Admin $2,300. Income tax similar. Total ≈ $7,650 + $2,300 + $7,500 = $17,450. Savings ~$1,525. Thin, and if any state fee exists, it vanishes.
Scenario 2: $150,000 Net Profit
Default LLC: SE tax on $150k ≈ $21,218 (15.3% of $138,525). Income tax ~$15,000. Total ~$36,218.
S corp: Salary $70k (reasonable for a skilled consultant), distributions $80k. Payroll tax $10,710. Admin $2,300. Income tax ~$15,000. Total ~$28,010. Savings ~$8,208. This is where the election clearly pays off.
Scenario 3: $300,000 Net Profit
Default LLC: SE tax hits cap; first $168,600 at 15.3% = $25,795, remaining $131,400 at 2.9% = $3,811, total $29,606. Income tax ~$35,000. Total ~$64,606.
S corp: Salary $120k (must be defensible), distributions $180k. Payroll tax on $120k = $18,360. Admin $2,300. Income tax ~$35,000. Total ~$55,660. Savings ~$8,946. Note savings plateau because Social Security cap limits further SE tax avoidance.
The takeaway: S corp tax benefit grows with profit but caps once salary covers the Social Security base. It is not infinite, and additional Medicare tax of 0.9% on wages above $200k can nibble at high earners.
Computing Your Precise Break-Even Point
The internet loves to say “switch at $50k,” but that ignores state fees and payroll costs. The precise break-even is when (SE tax saved on distributed profit) > (additional payroll + admin + state franchise tax). I start by computing operating profit with our Earnings Before Interest and Taxes (EBIT) Calculator to anchor the number.
Formula I use: Break-even profit ≈ (Annual S corp admin cost + state fee) / (SE tax rate on distributions). Since the 15.3% saves on the distribution portion up to the cap, if admin is $2,300 and state fee $0, you need about $15,000 of distributions to clear $2,300 (15.3% of $15k = $2,295). That’s why the $75k scenario gave small savings.
State Fee Impact on Break-Even
| State | Added S Corp Cost | Approx Extra Profit Needed |
|---|---|---|
| Texas | $0 state income tax, no franchise for small | $15k distributions |
| California | $800 min franchise + 1.5% net income | +$12k profit at $75k income |
| New York | $25–$100 min tax + commuter tax | +$3k–$5k |
| Tennessee | Excise 6.5% on net worth/apportioned | varies by receipts |
Most people don’t realize that in California, the S corp faces an $800 minimum franchise fee plus 1.5% of net income. On $75k profit, that’s $800 + $1,125 = $1,925 extra, wiping out federal savings. So CA break-even is closer to $120k–$150k. Always model state before electing.
What Is the Downside of Being an S Corp?
Despite tax savings, S corp status carries real constraints. First, ownership limits: only U.S. citizens or residents can be shareholders, max 100 owners, and one class of stock. If you plan foreign investors or venture capital, S corp is off the table. Second, reasonable-salary IRS scrutiny is not theoretical; mispricing triggers back taxes and penalties.
Third, administrative load is year-round. You must run payroll, file federal and state returns, and keep minutes. For a solo owner, that’s $2k+ annually. Fourth, S corps cannot retain earnings like C corps; they must distribute essentially all income, which can create personal cash-flow tax hits even if you don’t need the cash.
The 2% Rule for S Corps Explained Simply
What is the 2% rule for S Corps? Shareholders owning more than 2% of the company are treated like self-employed for fringe benefits. That means benefits like health insurance premiums, group term life, and cafeteria plans that are tax-free for <2% owners must be included in the >2% owner’s taxable wages. I learned this the hard way when a client’s $6,000 premium unexpectedly increased his W-2 income and we had to amend.
Other affected benefits: adoption assistance, transit passes, and employer-provided meals. The rule exists to prevent owner-employees from disguising tax-free compensation. If you’re a solo owner, you are by definition >2%, so plan to add those benefits to W-2.
Do you pay more taxes with an S corp? Yes, potentially. If your profit is low, the admin and payroll costs exceed SE tax savings. Also, in states that tax S corp income but not LLCs (rare, but some localities), you could owe more. The election is not a universal win.
At What Point Should I Switch from LLC to S Corp?
The switch makes sense when projected net profit consistently exceeds your state-adjusted break-even for two years. For a Texas solo consultant, that’s ~$60k–$70k; for a California one, ~$130k. If you have passive income over $3,000 from other sources, S corp losses may be suspended – an edge case many miss.
Steps for an LLC to elect S corp status: (1) Ensure eligible (U.S. owners only, <100). (2) File Form 2553 with the IRS within 2 months and 15 days of the start of the tax year. (3) Set up payroll immediately. When I first filed this for a client in 2019, I missed the deadline and had to use late-election relief under Rev Proc 2013-30, adding paperwork and delaying treatment by a quarter. Don’t repeat that.
If you miss the window, the IRS allows relief if you intended to elect and failed due to reasonable cause; you attach a statement to Form 2553. But it’s stressful. Mark the calendar for January 1 effective date.
State-Level Tax Nuances That Flip the Answer
State law diverges sharply. New York charges an S corp metropolitan commuter tax and a fixed dollar minimum tax based on receipts. Tennessee and Texas impose franchise/margin taxes that apply regardless of entity type but compute differently. New Hampshire exempts LLCs pass-through but has business profits tax that can hit S corps; nuances matter. Always check the specific state revenue department.
Most people don’t realize that some states (like Massachusetts) treat S corps identically to federal, while others (like California) layer franchise fees. If you operate in multiple states, nexus can force S corp apportionment that increases compliance cost. Factor a $300–$700 multi-state filing fee into break-even. An LLC default may be simpler if you’re a digital nomad crossing state lines.
The Decision Tree and Checklist I Use
Here is the applied framework. Run down the list; if all boxes tick, S corp likely better for taxes:
- Profit level: Expected net profit > state-adjusted break-even (use calculator above).
- State fee: Added S corp state cost < projected SE tax savings.
- Owner count: ≤100 U.S. citizen/resident owners, no foreign or entity owners.
- Passive income: No large passive losses that S corp suspension would waste.
- Reasonable salary: Defensible W-2 pay based on role (use BLS data).
- Admin appetite: Willing to spend $2k+ yearly on payroll and 1120-S.
If profit is below break-even or you need foreign investment, stay default LLC. The decision tree is not “S corp always,” it’s “S corp when margin clears cost.” I print this for every client meeting.
Advanced Edge Cases Before You Elect
One edge case: S corps with accumulated earnings and passive income exceeding 25% of gross receipts for three straight years risk termination. That’s rare for small service firms but matters if you hold rental income inside the entity. Another: converting from a C corp to S corp triggers built-in gains tax on appreciated assets for 5 years.
Also, S corp election is revocable, but switching back to LLC default requires IRS consent if within 5 years. Plan for the long haul. Use the models, respect the 2% rule, and you’ll make a tax choice grounded in data, not blog hype.
Putting It All Together: Your Next Steps
Start by computing true net profit after expenses using the EBIT tool. Then run the S-Corp vs LLC calculator with your state fee. If savings exceed $2,000 and you can defend a salary, file Form 2553 for January 1. Set up payroll before the first distribution. Keep documentation of salary rationale.
The question “s corp vs llc which is better for taxes” is answered by your own numbers, not a blanket rule. In my practice, clients above $120k profit in low-fee states almost always benefit; those below $60k rarely do. Run the math, respect the downside, and the decision becomes clear.
