The S-Corp question is the single most common thing freelancers ask me about. And I get it. The pitch sounds great: elect S-Corp, pay yourself a "reasonable salary," and save thousands on self-employment tax. But the pitch leaves out the compliance costs, the NJ-specific taxes, and the fact that at lower income levels, the savings can be zero or even negative.

The three scenarios below isolate the regular federal payroll-tax mechanics; they do not establish a universal breakeven point or a net-savings promise. A final comparison must model the owner's complete federal and NJ return. For a broader comparison, see the entity structure guide.

How S-Corp Savings Work

For an ordinary nonfarm sole proprietor, Schedule C profit generally is multiplied by 92.35% to determine Schedule SE line 4c net earnings. The 12.4% Social Security component applies only within the owner's remaining $184,500 combined wage base for 2026, while the 2.9% Medicare component has no comparable cap. Form 8959 separately tests Additional Medicare Tax against combined wages, railroad compensation, and self-employment income.

With an S-Corp, you split your business income into two buckets:

  • Salary (W-2): Subject to payroll taxes (the same 15.3%, split between employer and employee portions)
  • Distributions (profit above salary): Not subject to payroll or SE tax

The payroll-tax difference arises because reasonable W-2 compensation is subject to FICA while residual S-Corp profit is not subject to SE tax. Residual profit is not simply business profit minus salary: the corporation also deducts its employer share of FICA and other expenses. A stated payroll-tax difference is not net savings until income tax, QBI, NJ taxes, reasonable-compensation support, and compliance costs are included.

The Costs of S-Corp Compliance

Here's what the S-Corp pitch doesn't emphasize. Running an S-Corp costs money:

  • Payroll processing: You must run payroll for yourself, including withholding, quarterly 941 filings, W-2 preparation, and state payroll tax filings. Cost: $500 to $1,500 per year depending on the provider.
  • S-Corp tax return (Form 1120-S): A separate corporate return is required. CPA cost: $1,500 to $2,500 depending on complexity.
  • NJ Corporate Business Tax (CBT-100S): NJ S-Corps pay a minimum tax starting at $375 per year ($375-$1,500 based on gross receipts, per N.J.S.A. 54:10A-18(e)). This is on top of any NJ income tax you owe personally.
  • NJ payroll registration: You need to register with NJ for employer withholding, unemployment insurance, disability insurance, and workforce development. More forms, more compliance.
  • Bookkeeping: S-Corps should maintain clean books and a separate bank account. Additional bookkeeping cost: $500 to $1,000 per year.

Total annual compliance cost: roughly $3,000 to $4,000 on the low end, potentially $5,000+ if your situation is complex.

Scenario 1: $75K Net Income

As Sole Proprietor

  • Schedule C profit: $75,000
  • Schedule SE line 4c: $75,000 x 92.35% = $69,262.50
  • Regular SE tax, assuming no W-2 wages: $69,262.50 x 15.3% = $10,597.16

As S-Corp

  • Reasonable salary: $50,000 (you need to pay yourself enough to be credible for your work)
  • Payroll taxes on $50K salary: approximately $7,650 (15.3% combined employer + employee)
  • Residual S-Corp profit before other expenses: $75,000 - $50,000 salary - $3,825 employer FICA = $21,175
  • Gross payroll-tax difference: $10,597.16 - $7,650 = $2,947.16
  • Compliance costs: $3,000 to $4,000

Difference After Only the Stated Compliance Costs: About -$53 to -$1,053

What this does and does not show: In this assumed salary case, the gross payroll-tax difference does not cover the stated compliance-cost range. That is not a universal verdict at $75,000; other wages, QBI, income-tax deductions, NJ taxes, actual fees, and reasonable compensation can change the result.

Scenario 2: $100K Net Income

As Sole Proprietor

  • Schedule C profit: $100,000
  • Schedule SE line 4c: $100,000 x 92.35% = $92,350
  • Regular SE tax, assuming no W-2 wages: $92,350 x 15.3% = $14,129.55

As S-Corp

  • Reasonable salary: $60,000
  • Payroll taxes on $60K salary: approximately $9,180
  • Residual S-Corp profit before other expenses: $100,000 - $60,000 salary - $4,590 employer FICA = $35,410
  • Gross payroll-tax difference: $14,129.55 - $9,180 = $4,949.55
  • Compliance costs: $3,500 (midpoint estimate)

Difference After Only the Stated $3,500 Compliance Cost: $1,449.55

What this does and does not show: $1,449.55 is not net tax savings. It excludes the different income-tax deductions, QBI, NJ payroll and entity taxes, other wages, and return-specific items. Those must be modeled before an election decision.

Scenario 3: $150K Net Income

As Sole Proprietor

  • Schedule C profit: $150,000
  • Schedule SE line 4c: $150,000 x 92.35% = $138,525
  • Regular SE tax, assuming no W-2 wages: $138,525 x 15.3% = $21,194.33

As S-Corp

  • Reasonable salary: $75,000
  • Payroll taxes on $75K salary: approximately $11,475
  • Residual S-Corp profit before other expenses: $150,000 - $75,000 salary - $5,737.50 employer FICA = $69,262.50
  • Gross payroll-tax difference: $21,194.33 - $11,475 = $9,719.33
  • Compliance costs: $3,500

Difference After Only the Stated $3,500 Compliance Cost: $6,219.33

What this does and does not show: The remaining $6,219.33 is still not net tax savings. The full federal and NJ return can raise or lower it through income-tax deductions, QBI, wage-base interactions, NJ payroll and entity taxes, and actual compliance costs.

NJ-Specific Considerations

CBT-100S Filing

NJ S-Corps must file Form CBT-100S and pay a minimum tax. For S-Corps with gross receipts under $100K, the minimum is $375 (75% of the $500 C-Corp minimum per N.J.S.A. 54:10A-18(e)). This is a fixed cost that exists regardless of your income level and adds to the compliance burden at lower incomes.

NJ BAIT Election

The NJ Business Alternative Income Tax (BAIT) is an optional entity-level election for eligible pass-through entities. Its graduated rates apply to the statutory distributive-proceeds base, which is not universally identical to book profit, NJ-source income, or a generic owner's share. A qualifying entity payment generally is deductible federally under Notice 2020-75, and eligible owners claim NJ credits under the allocation rules.

BAIT can improve or worsen the modeled result depending on the statutory base, owner allocation, federal deduction choice and brackets, QBI interaction, NJ credit mechanics, cash timing, and compliance costs. It is not an automatic additional savings amount at any income level.

NJ Payroll Registration

When you elect S-Corp and start running payroll, you need to register as an NJ employer. This means:

  • NJ employer withholding registration
  • NJ unemployment insurance (UI) and temporary disability insurance (TDI) registration
  • NJ workforce development partnership fund contributions
  • Quarterly NJ-927 filing

Your payroll provider handles most of this, but you need to be aware that NJ has additional employer obligations beyond federal requirements.

The Decision Framework

Here's a framework for thinking about the S-Corp question:

  • Reasonable compensation: Document what the business would pay for the owner's services; do not use a desired distribution percentage.
  • Other wages and wage base: Existing W-2 wages can materially change the Schedule SE comparison.
  • Return-wide tax effects: Include employer payroll-tax and compliance-cost deductions, QBI, federal and NJ income tax, BAIT when eligible, and credits.
  • Administrative and legal factors: Include payroll, separate returns, state fees, benefits, ownership restrictions, and the value of limited-liability governance.

Other factors that matter: Do you plan to bring on partners or investors? (S-Corps have restrictions.) Do you want to keep things simple? (Sole prop is simpler.) Are you already incorporated as an LLC? (Electing S-Corp status is straightforward with Form 2553.)

Timing the Election

For a calendar-year taxpayer, Form 2553 generally is due by the 15th day of the third month; because March 15, 2026 fell on a Sunday, the timely-filing date rolled to Monday, March 16, 2026. Late-election relief may be available under Rev. Proc. 2013-30 when its requirements are met.

As of this July 15, 2026 review, the ordinary timely-filing date for a 2026 calendar-year election has passed. Analyze Rev. Proc. 2013-30 rather than assuming either that relief is automatic or that 2027 is the only possible effective year.

Key Legal and Tax Details

The David E. Watson, P.C. and Radtke cases are central reasonable-compensation authorities. Courts consider comparable pay, duties, time, experience, and business facts; salary cannot be lowered merely to increase distributions or QBI. NJ's CBT-100S minimum tax starts at $375 and rises with gross receipts. BAIT rates range from 5.675% to 10.9% on statutory distributive proceeds. The QBI deduction is permanent under OBBBA, but salary is not QBI and the remaining pass-through amount is subject to allocable-deduction, taxable-income, wage/property, and SSTB rules.

Frequently Asked Questions

At what income level does S-Corp election make sense for freelancers?

There is no universal income breakpoint. Model a defensible salary, Schedule SE under the owner's other-wage facts, both sides of FICA, income-tax deductions, QBI, federal and NJ income tax, BAIT if eligible, NJ payroll and minimum taxes, and compliance costs. Two freelancers with the same profit can reach different answers.

What are the annual compliance costs of an S-Corp?

Expect roughly $2,000 to $5,000 per year (most commonly $3,000-$3,500) for payroll processing ($500-$1,500), the S-Corp tax return ($1,500-$2,500), NJ's $375 S-Corp minimum tax ($375-$1,500 based on gross receipts), NJ payroll registration and quarterly filings, and additional bookkeeping. These are fixed costs regardless of income.

What is a reasonable salary for an S-Corp owner?

There is no single number. The IRS evaluates reasonable compensation based on comparable salary data for your role and industry, the amount of time you spend on the business, and the company's revenue. Courts in David E. Watson, P.C. v. United States and Radtke v. United States established that salaries must reflect what you would pay someone to do your job.

Can I still elect S-Corp status if I missed the March 15 deadline?

Potentially. The IRS allows late elections under Rev. Proc. 2013-30 if you can show reasonable cause and file within 3 years and 75 days of the intended effective date. Otherwise, the election takes effect the following tax year.
