What's different in Newark
- Local income tax
- No city income tax in Newark.
- Newark Payroll Tax
- Employers pay 1% of wages for services performed in Newark, or supervised from Newark. Employers whose workforce is more than 50% Newark residents may qualify for a reduced 0.50% rate with residency documentation. Returns are filed quarterly, due the 30th day after each quarter ends. The tax is on wages paid to employees; the city page does not describe it as applying to a solo worker's own self-employment income.
- Also worth knowing
- Newark has no personal income tax on residents or the self-employed; its payroll tax falls on employers. Newark runs an online business license portal through its Office of Central Licenses and Permits (a new portal went live September 8, 2026; https://www.newarknj.gov/35/Business), but the city site does not say whether a home-based self-employed person needs a city license. New Jersey S4219 (P.L.2025, c.314, approved January 20, 2026) concerns administration of the employer payroll tax and requires disclosure of certain state taxpayer information (https://www.njleg.state.nj.us/bill-search/2024/S4219).
New Jersey rules for consultants
- State income tax (2026)
- New Jersey has a graduated state income tax for 2026: 1.4% to 10.75% (top rate starts at $1,000,000 for single filers).

- State estimated tax
- You must make estimated payments if you expect to owe more than $400 in New Jersey income tax for the year after withholding and credits. Same dates as federal (April 15, June 15, September 15, January 15). Farmers and fiscal-year filers follow the NJ-1040-ES instructions. Form NJ-1040-ES.
- ABC test and new worker-classification rule (N.J.A.C. 12:11)
- New Jersey presumes a worker is an employee unless the business proves all three ABC prongs: free from control, work outside the usual course or places of business, and an independently established trade. NJDOL adopted rules on May 5, 2026 codifying the test under the unemployment, wage-and-hour, and wage-payment laws, with an anticipated June 1, 2026 effective date and an October 1, 2026 operative date.
- State retirement program
- RetireReady NJ (New Jersey Secure Choice Savings Program) is live. It is built around W-2 employers and does not cover 1099 contractors through the employer mandate; self-employed residents can enroll on their own.
Federal rules for 2026
Solo 401(k) up to $72,000
A one-person consultancy can contribute a $24,500 employee deferral plus an employer share of about 20% of net self-employment earnings, up to $72,000 in 2026, plus an $8,000 catch-up at 50 or older ($11,250 at ages 60 to 63).
The S-corp trade-off
Electing S-corp status can cut payroll tax, but the salary you pay yourself also sets your Solo 401(k) room. Run both sides before you elect.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
Self-employment tax
On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.
A worked example
| Self-employment tax (sole proprietor) | $21,194 |
|---|---|
| Solo 401(k) maximum | $52,381 |
| SEP IRA maximum | $27,881 |
| Payroll tax saved as an S-corp on a $75,000 salary | $9,719 |
| Solo 401(k) maximum as that S-corp | $43,250 |
Federal figures only, before state and local taxes. Simplified: excludes the QBI deduction and the 0.9% Additional Medicare Tax. Computed from 2026 IRS limits (Notice 2025-67, Rev. Proc. 2025-32) and the SSA wage base.
