Payroll costs the state adds

What New Jersey charges an employer on top of wages: unemployment tax, and any paid-leave or disability program funded through payroll, and who must carry workers’ comp. Federal Social Security, Medicare and unemployment tax apply in every state and are already in the calculator. Workers’ comp premiums depend on the class code and the insurer, so the card gives the rules, not a rate.

State unemployment tax (SUTA)

Rate year runs July 1 to June 30. NJDOL, fiscal year 2027 (from July 1, 2026): new-employer UI 2.6825% plus 0.1175% workforce development/supplemental workforce funds = 2.8%. Disability insurance (0.5% employer) is separate and not included.

Per tech, a year 2.80% × $44,800 = $1,254At the new-employer rate, for a plumber paid the state median ($37.61 × 2,080 h = $78,229). The calculator uses the rate alone.

Workers’ compensation

New Jersey Department of Labor and Workforce Development, Division of Workers' Compensation

Who must carry it
Any employeeEvery New Jersey employer not covered by a federal program must have workers’ compensation insurance or approved self-insurance as soon as one person (other than the owner of a sole proprietorship, or the partners or LLC members) works for pay; there is no minimum payroll and no exclusion for family members (N.J.S.A. 34:15-71). Failing to insure can bring penalties of up to $5,000 for the first 10 days and $5,000 for each further 10 days, and a stop-work order (N.J.S.A. 34:15-79). nj.gov
Where to buy it
Private insurersCoverage is bought from any of the more than 400 private insurers licensed to sell workers’ compensation in New Jersey (directly, or through an agent or broker), or the employer is approved to self-insure by the Department of Banking and Insurance (N.J.S.A. 34:15-77). The NJ Compensation Rating and Inspection Bureau helps employers who have trouble obtaining coverage. nj.gov
Owners
Corporate officers who are paid count as employees: a corporation must insure as soon as any one person, officers included, is paid, with no single-officer exemption. Partners, LLC members and sole proprietors are not counted and are not required to be covered, but may choose to cover themselves; corporate officers actively engaged in the business can be held personally liable for failure to insure (N.J.S.A. 34:15-79). nj.gov
Construction
A contractor who hires a subcontractor that does not carry the required workers’ comp becomes liable for compensation due the subcontractor’s employees, with a right to recover from the subcontractor (N.J.S.A. 34:15-79(a)). Misclassifying employees as independent contractors is itself an offense and can bring a stop-work order at every site where the violation occurred, with penalties of $1,000 to $5,000 a day for ignoring it (34:15-79(a), (d), (e)). pub.njleg.gov

What New Jersey’s tax agency says about repair and installation labor on buildings and the parts and fixtures that go into them. This is what the agency’s pages say, not tax advice.

Labor
DependsRepair, maintenance and installation labor that isn’t an exempt capital improvement is taxed. Work that results in an exempt capital improvement isn’t, whether or not materials and labor are itemized.Fixing faulty plumbing or electrical outlets is a taxable repair; a new hot water heater, central air conditioner or heating system, or rewiring, is an exempt capital improvement. Repairs to home heating systems serving up to three families are exempt.
Materials
Contractor, when buyingThe contractor pays tax on materials when buying them. On a taxable job only the separately stated cost of materials is left out of the taxed amount; an unitemized bill is taxed in full.
Also
For an exempt capital improvement the owner gives the contractor Form ST-8.

Licenses and state fees

The license a shop needs from the state to contract for each trade, the board that issues it and the fees on its own schedule. Cities and counties can add their own licenses, registrations and permit fees; exam vendors and fingerprinting may charge more.

Plumbing

Beyond the trade license

Contractor registration, bond and insurance the state asks of a trade shop

Registration
Home improvement contractors must register with the Division of Consumer Affairs, but plumbers, electrical contractors and other state-licensed professionals working within the scope of their license do not have to register. A new Home Improvement and Home Elevation Contractor Licensing Act (P.L.2023, c.237, approved January 8, 2024) will replace registration with a board license; its licensing sections stay inoperative until six months after the new board adopts rules, and it keeps the exemption for electrical contractors, master plumbers and other state-licensed trades. njconsumeraffairs.gov · pub.njleg.gov
Bond
$3,000A master plumber must keep a $3,000 surety bond running with the license for each two-year term; a master HVACR contractor must file a $3,000 surety bond; and an electrical contracting business needs a $1,000 surety bond in favor of the State for each 36-month term (N.J.S.A. 45:5A-19). njconsumeraffairs.gov
Insurance
A master HVACR contractor offering services to the public needs general liability insurance of $500,000 combined property damage and bodily injury per occurrence; an electrical contracting business permit needs general liability insurance (or a bank letter of credit) of at least $300,000. The master plumber overview lists a surety bond but no insurance minimum. njconsumeraffairs.gov

Plumbers, electrical contractors and HVACR contractors are licensed by state boards in the Division of Consumer Affairs; municipalities issue construction permits, and for plumbing or electrical work the permit must be signed and sealed by the New Jersey licensed master plumber or electrical contractor.

What New Jersey law says about lien rights on private jobs — the notices, the deadline to file and the deadline to sue — and whether a statute sets payment deadlines or caps retainage. Read from the statute itself; it is not legal advice.

Mechanic’s lien

N.J.S.A. 2A:44A-1 to 2A:44A-38Construction Lien Law

You, hired by the owner
On commercial jobs no notice is required before filing. On a residential construction contract every lien claimant, including a contractor hired by the homeowner, must first lodge a Notice of Unpaid Balance and Right to File Lien within 60 days after the last work or materials, serve it, and demand expedited arbitration within 10 days (N.J.S.A. 2A:44A-21(b)). lis.njleg.state.nj.us
Subs and suppliers
Notice requiredNew Jersey has no preliminary notice for subs or suppliers on commercial jobs; they lodge the lien claim within 90 days after their last work (N.J.S.A. 2A:44A-6). On residential jobs they, like the prime, must lodge the Notice of Unpaid Balance within 60 days and go through expedited arbitration first (N.J.S.A. 2A:44A-21). lis.njleg.state.nj.us
File the lien
90 daysLodge the signed, verified lien claim with the county clerk within 90 days after the last work, services, material or equipment (N.J.S.A. 2A:44A-6(a)(2)). On a residential contract the claim is lodged within 10 days after receiving the arbitrator’s decision and within 120 days after the last work. lis.njleg.state.nj.us
Enforce it
1 yearFile suit in Superior Court within one year of the last work, services, material or equipment, or within 30 days after a written demand from the owner or contractor to sue, or the lien is forfeited and must be discharged (N.J.S.A. 2A:44A-14(a)). lis.njleg.state.nj.us
Homes
Residential construction contracts follow a separate track: Notice of Unpaid Balance within 60 days, a demand for expedited arbitration within 10 days of lodging it, and the lien claim itself within 10 days after the arbitrator’s decision and within 120 days after last work (N.J.S.A. 2A:44A-6, 2A:44A-21). lis.njleg.state.nj.us

Statutes read

Payment deadlines and retainage

Private jobs (public contracts have their own rules)

Prompt payment
Statute sets deadlinesUnder N.J.S.A. 2A:30A-2, a billing is deemed approved 20 days after the owner receives it unless the owner states in writing what is withheld and why, and the owner must pay within 30 calendar days after the billing date; the prime must pay subs within 10 calendar days after it is paid. Late payments carry interest at prime plus 1%, an unpaid party may suspend work after 7 days’ written notice, and the winner in court gets attorney fees. lis.njleg.state.nj.us
Retainage
No statute caps private-job retainage in New Jersey; once billed, retainage must be paid within 30 calendar days after the billing date like any other payment, and passed down to subs within 10 calendar days after receipt (N.J.S.A. 2A:30A-2). lis.njleg.state.nj.us

Heating carries the load at Newark airport: 4,701 heating degree days a year against 1,270 cooling degree days, peaking in January (1,000).

The lightest months for heating and cooling together are May and September (193 and 193 degree days).

Nights at or below 32 °F: about 80 a year, ten or more a month in December through March. Days reaching 90 °F: about 28 a year, the most in July.

Weighted by where New Jersey’s people live, NOAA’s statewide normals (1981–2010) are 5,324 heating and 850 cooling degree days — 25th for heating and 24th for cooling among the 48 contiguous states (the contiguous U.S.: 4,332 and 1,272).
