Important: This is a Rough Estimate

  • This calculator uses 2026 SE tax rates: 12.4% Social Security on the first $184,500 of net earnings (SSA contribution and benefit base), plus 2.9% Medicare on all earnings. S-Corp scenario uses payroll tax (employer + employee combined) of 15.3% on W-2 salary up to the wage base.
  • Actual S-Corp savings depend on factors this calculator doesn't model: federal income tax bracket changes, state income tax (NJ Gross Income Tax), QBI deduction interaction, retirement plan contribution capacity (S-Corp enables larger SEP-IRA / Solo 401(k) deductions), and NJ BAIT election eligibility.
  • S-Corp compliance costs include payroll setup ($500-1000), quarterly Form 941 filings, quarterly NJ-927, separate Form 1120-S preparation ($1,200+), and reasonable compensation documentation. ProAxis estimates ~$2,000/year in additional compliance vs an LLC.
  • The IRS requires "reasonable compensation" — too-low salary creates audit exposure. Industry comparables and documented analysis are required.

Worked Example — $150,000 NJ Sole Proprietor

A NJ sole proprietor running a single-member LLC nets $150,000 in annual business profit. The owner is considering whether to elect S-Corporation status. Here's how the calculator breaks down the math:

Without S-Corp election (current LLC): All $150,000 of net profit is subject to self-employment tax. Using 2026 rates: 12.4% Social Security on the first $184,500 wage base + 2.9% Medicare on all earnings, with the 92.35% Schedule SE adjustment. SE tax owed: approximately $21,194 per year.

With S-Corp election: Owner takes a reasonable W-2 salary of $75,000 (50% of net — supportable for most service businesses based on industry comparables). Payroll tax on $75,000: approximately $11,475. Remaining $75,000 of profit passes through as a distribution NOT subject to self-employment tax. Gross savings: $21,194 − $11,475 = $9,719/year.

Net of S-Corp compliance costs: Subtract the estimated $2,000/year in additional compliance (payroll setup, quarterly Form 941 + NJ-927 filings, separate Form 1120-S preparation, reasonable comp documentation). Net annual savings: approximately $7,700/year.

Plus the BAIT election layer: Once the S-Corp election is made, the owner becomes eligible for the NJ BAIT election. For this $150K business with NJ income, the BAIT can save an additional $5,000-$15,000/year by bypassing the federal SALT cap. Combined S-Corp + BAIT savings often double the standalone S-Corp benefit.

After You Run the Calculator

The calculator output is a starting point, not a decision. Here's what to do with the result:

  • If the calculator shows under $3,000/year in net savings: The S-Corp election usually isn't worth the compliance complexity. Stay as an LLC and revisit annually as income grows.
  • If the calculator shows $3,000-$8,000/year in net savings: Borderline. The election makes sense if you're committed to operating cleanly with payroll, quarterly filings, and reasonable comp documentation. Worth a conversation with a CPA.
  • If the calculator shows $8,000+/year in net savings: The election almost certainly makes sense. Add the NJ BAIT election analysis on top — it likely doubles the savings. Schedule a CPA consultation to validate the analysis and execute the Form 2553 filing.

Whatever the result, document the inputs you used. When you talk to a CPA, you'll want to confirm whether your "reasonable salary" estimate is defensible based on industry comparables and IRS guidance. A CPA's job is partly to validate the math you've already started.

How to Use This Calculator

  1. Enter your net business income — total revenue minus all deductible expenses, BEFORE paying yourself a salary. If your business made $200K in revenue and spent $50K on expenses, enter $150,000.
  2. Enter a reasonable W-2 salary — what would you legitimately pay an outside hire to do your job? Industry comparables: 40-60% of net business income is typical for service businesses. Document the analysis with peer salary data.
  3. Read the results — the calculator shows SE tax under the LLC scenario, payroll tax under S-Corp, and the estimated annual savings net of compliance costs.
  4. Apply the $60K rule — if your savings show under ~$3,000/year, the S-Corp election usually isn't worth the compliance complexity. Above $3,000-$5,000/year savings, the S-Corp typically makes sense.

Frequently Asked Questions

How much can I save by electing S-Corp status for my NJ LLC?

Savings depend on net business income and what counts as a reasonable W-2 salary. For a NJ sole proprietor netting $150,000 paying themselves a $75,000 salary under an S-Corp election, the calculator estimates roughly $9,719 in gross self-employment tax savings and about $7,700 net of $2,000 in added compliance costs. The savings scale with net income above the reasonable salary line, so higher-earning service businesses see larger benefits.

What inputs does the S-Corp savings calculator require?

Two inputs. First, annual net business income — total revenue minus all deductible expenses, before paying yourself any owner compensation. Second, a reasonable W-2 salary — what you would pay an outside hire for the same role, typically 40-60% of net business income for service businesses. The calculator runs in your browser, requires no signup, and does not save your inputs.

Is the S-Corp election always worth it?

No. If the calculator shows under $3,000/year in net savings after the estimated $2,000 in added compliance costs, the S-Corp election usually is not worth the extra complexity. Between $3,000 and $8,000 in net savings, the election is borderline and depends on whether you are willing to run payroll, file quarterly Form 941 and NJ-927, and document reasonable compensation. Above $8,000, the election almost always makes sense, especially when paired with the NJ BAIT election.

What does the S-Corp calculator NOT include?

The calculator focuses on self-employment vs. payroll tax. It does not model federal income tax bracket effects, NJ Gross Income Tax, the QBI deduction interaction, retirement plan contribution capacity, or NJ BAIT eligibility. Any of these can shift the real-world savings significantly. For a complete analysis, ProAxis runs the full calculation including state tax, QBI, and BAIT layering as part of a free consultation.

What tax rates does the S-Corp savings calculator use?

The calculator uses 2026 federal rates: 12.4% Social Security on net earnings up to the $184,500 wage base, plus 2.9% Medicare on all net earnings. The LLC scenario applies the 92.35% Schedule SE adjustment to net business income. The S-Corp scenario applies combined employer-and-employee payroll tax of 15.3% on the W-2 salary up to the same Social Security wage base. The estimated $2,000 annual compliance cost reflects payroll setup, quarterly filings, and Form 1120-S preparation.
