LLC vs S-Corp Tax Savings Calculator: Which Saves You More in 2026
The single biggest tax decision for small business owners: Should you stick with LLC taxation or elect S-Corp status? The answer depends entirely on your profit level—and the savings can be $10,000+ per year.
Quick Answer: If your business profit exceeds $60,000/year, S-Corp election typically saves money. Below that, the administrative costs often outweigh tax benefits. Read on for the math.
The Core Difference: Self-Employment Tax
Here's why S-Corp can save you thousands:
LLC Taxation (Default)
- All profit is subject to 15.3% self-employment tax
- Plus regular income tax (10-37% based on bracket)
- Simple—no payroll required
S-Corp Taxation
- Only your reasonable salary is subject to 15.3% payroll tax
- Remaining profit distributions are not subject to payroll tax
- Requires formal payroll, quarterly filings, more admin
The Math: Social Security tax (12.4%) applies to first $176,100 of wages in 2026. Medicare (2.9%) applies to all wages. S-Corp lets you avoid these taxes on distributions above your salary.

The Break-Even Point: When S-Corp Makes Sense
| Annual Profit | S-Corp Savings | Recommendation |
|---|---|---|
| $30,000 | -$800 | Stick with LLC |
| $50,000 | +$2,190 | S-Corp worth considering |
| $75,000 | +$4,500 | S-Corp strongly recommended |
| $100,000 | +$6,780 | S-Corp almost always worth it |
| $150,000+ | +$8,000+ | S-Corp essential |
Rule of Thumb: At $60,000+ annual profit, S-Corp election typically saves enough to justify the extra paperwork. Below $40,000, administrative costs often exceed tax savings.
The "Reasonable Salary" Requirement
S-Corp savings depend on taking a reasonable salary—not zero, not artificially low. The IRS scrutinizes this.
What Counts as "Reasonable"?
- Industry standards: What do others in your role/industry earn?
- Time commitment: Full-time work = full-time salary
- Business role: What would you pay someone to do your job?
- Location: Adjust for cost of living
Example: Software Consultant
Business profit: $150,000/year
Reasonable salary: $75,000-90,000 (based on market rates for senior developers)
Too aggressive: $30,000 salary → IRS audit risk
Sweet spot: 50-60% of profit as salary, rest as distributions
IRS Red Flags
- Salary below industry minimums
- Salary unchanged despite profit growth
- Zero salary in profitable years
- Salary far below non-owner employees
S-Corp Administrative Requirements (The "Cost")
S-Corp savings aren't free. You'll need:
Required Setup
- Form 2553: S-Corp election (file within 2.5 months of formation)
- Payroll system: To process salary, withhold taxes
- Quarterly payroll filings: Form 941
- W-2 issuance: To yourself by January 31
- Separate business account: Strictly required
- Form 1120-S: Corporate tax return (due March 15)
Estimated Annual Costs
| Item | Low Cost | Mid Cost |
|---|---|---|
| Payroll Service | $500/year | $1,200/year |
| Tax Preparation (1120-S) | $800 | $1,500 |
| State Franchise Tax | $0-800 | $800 |
| Total Annual Admin | $1,300 | $3,500 |
When LLC Taxation is Better
Don't automatically elect S-Corp. Stick with LLC when:
- Profit under $50,000: Admin costs eat savings
- Fluctuating income: S-Corp locks you into salary commitment
- Early-stage business: Reinvesting all profits (S-Corp salary required regardless)
- Passive income: Rentals, investments—no self-employment tax anyway
- Want simplicity: S-Corp adds 10-15 hours/year of admin
S-Corp vs LLC: Quick Comparison
| Factor | LLC (Default) | S-Corp Election |
|---|---|---|
| Self-Employment Tax | All profit taxed | Only salary taxed |
| Payroll Required | No | Yes |
| Tax Return | Schedule C | Form 1120-S + K-1 |
| Quarterly Filings | Estimated taxes only | Payroll + estimated taxes |
| Admin Time | 2-4 hours/year | 15-25 hours/year |
| Annual Cost | $0-200 | $1,500-3,500 |
| Best For | <$60K profit, simplicity | >$60K profit, max savings |
State-Specific Considerations
S-Corp taxation varies by state:
High-Franchise-Tax States (S-Corp Less Attractive)
- California: $800 minimum franchise tax + 1.5% on net income
- New York City: S-Corps subject to NYC corporate tax
- New Jersey: S-Corps pay separate state tax
No-State-Income-Tax States (S-Corp More Attractive)
- Texas, Florida, Nevada, Wyoming, Washington, South Dakota
- Some have gross receipts taxes (Texas franchise tax)
Pro Tip: Run the numbers for YOUR state. California's franchise tax can eliminate S-Corp savings for businesses under $100K profit.
How to Elect S-Corp Status
- Form LLC with your state
- Get EIN from IRS (online, instant)
- File Form 2553 within 2.5 months of formation OR by March 15 for existing LLCs (effective current tax year)
- Set up payroll (Gusto, ADP, or local provider)
- Begin taking salary (regular payroll schedule)
- Track distributions separately from salary
Timing: You can elect S-Corp at any time, but it only takes effect for the current tax year if filed by March 15. Otherwise, it applies to next year.
Common Mistakes to Avoid
- Election too late: File Form 2553 on time or wait a year
- Salary too low: IRS will reclassify distributions as wages + penalties
- Missing payroll deadlines: Penalties add up fast
- Commingling funds: Strict separation required
- Forgetting state requirements: Some states need separate S-Corp election
- Not taking distributions: S-Corp only saves if you actually take them
