The complete NJ business formation guide: $125 filing fee, step-by-step formation, NJ-REG tax registration, LLC vs. S-Corp decision, and every first-year deadline. Built by a NJ-licensed CPA who does this every day.
The complete formation sequence from name search to fully registered. Total mandatory government cost: $125. Timeline: 1-3 business days.
Search at njportal.com/DOR/BusinessNameSearch (free, instant). Name must include 'LLC,' 'L.L.C.,' or 'Limited Liability Company' and be distinguishable from existing entities. Optional name reservation: $50 for 120 days.
Every NJ LLC needs a registered agent with a physical NJ street address (no PO boxes). You can be your own agent at no cost if you're a NJ resident available during business hours. Commercial services: $99-$300/year.
File online at njportal.com/DOR/BusinessFormation. Processing: minutes to 1-3 business days. You'll need: LLC name, principal office address, registered agent name/address, purpose ('any lawful activity'), and member/manager names.
Apply at irs.gov (free, immediate online issuance, Mon-Fri 7 AM-10 PM ET). You'll need the LLC's legal name and the responsible party's SSN. Form the entity first, then apply. One EIN per responsible party per day.
File at njportal.com/DOR/BusinessRegistration. This single form registers you for all applicable NJ taxes: withholding, sales tax, SUI, SDI, FLI, and WFD. Must be filed within 60 days of formation and at least 15 business days before your first taxable sale.
Bring your Certificate of Formation, EIN confirmation, and operating agreement. Many NJ banks (Chase, TD Bank, PNC) offer free business checking. This is non-negotiable for maintaining your liability protection.
NJ has no statewide business license. Check your municipality for mercantile licenses ($50-$500), zoning permits, certificates of occupancy, health permits, and industry-specific licenses through the NJ Division of Consumer Affairs.
Choosing the right structure affects your taxes, liability protection, and compliance burden. Here's how NJ's entity types stack up.
| Entity | Formation Cost | NJ Tax Treatment | Liability Protection | BAIT Eligible |
|---|---|---|---|---|
| Sole Proprietorship | ~$50 (county trade name) | GIT (1.4%-10.75%) + SE tax (15.3%) | None | No |
| Single-Member LLC | $125 + $75/yr | Disregarded (Schedule C + GIT). No CBT. | Yes | No |
| Multi-Member LLC | $125 + $75/yr | Partnership (NJ-1065). $150/member filing fee (3+ members). | Yes | Yes |
| LLC + S-Corp Election | $125 + $75/yr | CBT-100S (minimum tax $375-$1,500+). FICA savings on distributions. | Yes | Yes |
| C-Corporation | $125 + $75/yr | CBT (6.5%-9%) + 2.5% Transit Fee (if >$10M). Double taxation. | Yes | No |
| General Partnership | ~$50 (county trade name) | Partnership (NJ-1065). $150/partner filing fee (3+ partners). | None (unlimited joint & several) | Yes |
| Limited Partnership (LP) | $125 + $75/yr | Partnership (NJ-1065). Limited partners shielded; GP exposed. | Partial | Yes |
| LLP | $125 + $75/yr | Partnership (NJ-1065). Co-partner malpractice shielded. | Partial | Yes |
| Professional Corp (PC/PA) | $125 + $75/yr | C or S election. All shareholders must hold active licenses. | Yes (not own malpractice) | If S-Corp |
NJ does not offer a PLLC structure. DORES does not include PLLC as a filing type. Licensed professionals must use a Professional Corporation (PC/PA), a standard LLC (where permitted by their licensing board), or an LLP. A proposed PLLC bill (A2285) has not been enacted.
Professions requiring professional entities (N.J.S.A. 14A:17-3): CPAs, architects, optometrists, professional engineers, land surveyors, land planners, chiropractors, physical therapists, registered professional nurses, psychologists, dentists, osteopaths, physicians and surgeons, podiatrists, veterinarians, and attorneys-at-law. Some professions (e.g., CPAs) may also use LLCs under their licensing board rules.
The S-Corp election saves self-employment tax by splitting income between W-2 wages (subject to FICA at 15.3%) and distributions (not subject to FICA). But NJ adds a unique wrinkle: S-Corps must pay the CBT minimum tax that disregarded single-member LLCs avoid entirely. Here's the real math at five income levels:
| Net Income | Salary (%) | Approx. Annual Savings | Verdict |
|---|---|---|---|
| $75,000 | $45,000 (60%) | ~$350 | Not worth it |
| $100,000 | $55,000 (55%) | ~$1,950 | Marginal |
| $150,000 | $75,000 (50%) | ~$3,800 | Clearly beneficial |
| $250,000 | $100,000 (40%) | ~$9,100 | Strong savings |
| $500,000 | $150,000 (30%) | ~$6,700 | Strong (SS cap effect) |
Notes: Savings figures are net of NJ CBT minimum tax ($375-$1,500) and assume ~$2,000/year in additional S-Corp compliance costs (payroll service, additional tax return). The $500,000 level shows lower savings than $250,000 because both scenarios exceed the Social Security wage base ($184,500 for 2026). Savings at $500,000 come primarily from avoiding 2.9% Medicare + 0.9% Additional Medicare Tax on distributions.
Break-even point: The S-Corp election becomes worth the additional compliance cost at approximately $80,000-$100,000 in net business income, factoring in NJ's CBT minimum tax and ~$2,000 in annual payroll and tax prep costs.
Alex is a freelance graphic designer in NJ earning $150,000/year in net business income. They're currently a single-member LLC (disregarded entity). Should they elect S-Corp status?
| Tax Component | As LLC (Disregarded) | As S-Corp ($75K salary) |
|---|---|---|
| Self-employment tax (15.3% on 92.35%) | ~$21,200 | - |
| Employer + employee FICA on $75K salary | - | ~$11,475 |
| FICA on $75K distribution | - | $0 |
| NJ CBT minimum tax | $0 | $563 |
| Additional payroll/compliance costs | $0 | ~$2,000 |
| Total employment tax + compliance cost | ~$21,200 | ~$14,038 |
| Annual savings with S-Corp | ~$7,162 |
Bonus: By electing S-Corp status, Alex also unlocks BAIT eligibility. If Alex's property taxes and state income taxes exceed the $40,000 SALT cap (common in NJ), the BAIT election provides an additional federal deduction that a single-member LLC cannot access.
Should you form in Delaware instead? For NJ-based businesses, the answer is almost always no. Here's why.
| Category | NJ | NY | PA | DE |
|---|---|---|---|---|
| LLC Formation Fee | $125 | $200 | $125 | $110 |
| Publication Requirement | None | $200-$1,900+ | None | None |
| Annual Report / Recurring Fee | $75/yr | $9 biennial | $7/yr | $300/yr franchise tax |
| First-Year Minimum | ~$200 | ~$450-$2,150+ | ~$132 | ~$410+ |
Bottom line: NJ's key advantage over New York is no publication requirement (saves $200-$1,900+). Delaware's $300/year franchise tax and need for a registered agent add up, plus you'd still need to register as a foreign LLC in NJ if you operate here. For a NJ-based business, forming in NJ is almost always the right choice.
Every deadline from formation through your first tax filing season. This assumes a multi-member LLC with employees that collects sales tax.
These are the errors I see most often from new NJ business owners. Every one of them is avoidable with proper setup from day one.
NJ charges underpayment interest at 10% (prime + 3%) for 2026. NJ's safe harbor requires 80% of current-year liability (not 90% like federal). Worse: if you pay less than 80% by April 15, NJ retroactively denies your filing extension and adds 5%/month late filing penalties on top.
Sales tax is a trust fund tax - you personally liable regardless of entity structure. If you sell taxable goods or services without registering for a Certificate of Authority, the NJ Division of Taxation can assess you going back 4 years (with no limit if returns were never filed).
NJ presumes all workers are employees. The employer must prove all three prongs: (A) freedom from control, (B) service outside the usual course of business, and (C) an independently established business. Penalties include $1,000 per worker, 5% of gross earnings, 200% liquidated damages, and stop-work orders at $5,000/day.
LLC is a legal structure; S-Corp is a tax election. You need IRS Form 2553 filed within 75 days of the tax year start AND a separate NJ S-Corp election within 3.5 months. Missing NJ's election means you're taxed as a C-Corp for NJ purposes - even if the IRS accepted your federal S election.
The $75 annual report is due the last day of your formation anniversary month. Two consecutive missed years triggers administrative dissolution. Your liability protection vanishes, you lose operating authority, and your business name becomes available to anyone. Reinstatement costs $170+ plus all missed reports.
Under Verni v. Harry M. Stevens, Inc., NJ courts look for commingling of funds as the single most damaging factor for veil-piercing. Use a dedicated business bank account from day one. Zero personal purchases on the business account. Zero business expenses on personal cards.
NJ has 564 municipalities, each with their own licensing requirements. There is no statewide business license. Common needs include mercantile licenses ($50-$500), zoning permits, certificates of occupancy, and health permits. Operating without proper local registration can result in fines or forced closure.
NJ-REG is the omnibus registration that creates all applicable tax accounts simultaneously. Here's what each account covers and when it applies.
Required for any employer paying wages to NJ workers. Rates: 1.4%-10.75%. Filing frequency assigned by the Division: weekly, monthly (NJ-500), or quarterly (NJ-927). Annual reconciliation: NJ-W-3 due February 15.
Required for selling taxable goods/services. Rate: 6.625% statewide. New businesses default to quarterly filing (ST-50, due 20th of month after quarter). Monthly payments required if prior-year collections exceed $30,000.
Triggered when paying $1,000+ in wages/year. New employer SUI rate: 2.8%. Employee SDI: 0.23%, FLI: 0.33%, WFD: 0.425%. Employer WFD: 0.1175%. Filed quarterly via NJ-927 + WR-30.
Applies to all corporations (C-Corp and S-Corp) with NJ nexus. S-Corps file CBT-100S (usually minimum tax: $375-$1,500+). C-Corps file CBT-100 at 6.5%-9% graduated rates. Estimated payments if liability exceeds $500.
What you'll actually spend in year one depends on your entity complexity, whether you have employees, and how much professional help you need.
