New Jersey has the second-highest top marginal individual income tax rate in the country at 10.75%, across seven brackets, and the highest combined state-and-local burden of any state for top earners. New Jersey is also one of only two states that do not honour Social Security benefits as fully tax-exempt, which pushes the effective rate on retirement income above the headline top rate.
Local taxes: New Jersey is unusual because roughly 560 municipalities each collect their own earned income tax, and the state requires municipalities to offer at least one rate that raises the same amount as the state rate. This means a New Jersey contractor's combined rate can exceed 11% once the local earned income tax is added.

Tax Strategy for consultants
A consultant's deduction profile is dominated by the home office, professional liability insurance, and continuing education, which is a required cost of maintaining a licence or certification. Professional liability insurance is frequently overlooked and is fully deductible as an ordinary and necessary business expense, as is the cost of the credentials clients increasingly require.
Consulting revenue often arrives in large retainers or milestone payments rather than monthly hours. If a client pays a quarterly retainer in advance, the income is taxable on receipt, which can push a single quarter's liability well above a straight-line division of the annual total.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.
