DIRECT ANSWER
What to know first
New Jersey generally requires a resident or nonresident to make estimated payments when expected New Jersey tax after withholding and credits is more than $400 and a return is otherwise required. For calendar-year taxpayers, the four general 2026 installment dates are April 15, June 15, and September 15, 2026, followed by January 15, 2027. Use New Jersey's own NJ-1040-ES worksheet and payment system; an IRS projection or federal payment does not calculate or pay New Jersey tax.
Who may need New Jersey estimated payments
The NJ-1040-ES instructions apply a New Jersey-specific balance-due test to residents and nonresidents who otherwise have a filing requirement. Common triggers include self-employment, business or rental income, investment gains, retirement distributions, equity-compensation events, and wage withholding that does not cover the expected New Jersey liability.
Filing thresholds, resident or nonresident status, credits, and payments made on a taxpayer's behalf can change the result. Use the current New Jersey worksheet for the applicable filing status and return type rather than importing a federal estimated-tax amount.
2026 NJ-1040-ES installment dates
New Jersey's instructions also address when the payment requirement begins later in the year and when filing and paying the annual return can replace the final installment. Verify the current form and any announced disaster relief before relying on a date.
| Installment | General payment date | What to review |
|---|---|---|
| First | April 15, 2026 | Expected New Jersey income, tax, withholding, credits, and prior payments |
| Second | June 15, 2026 | Changes in income, withholding, and credits through spring |
| Third | September 15, 2026 | Midyear business, rental, investment, or stock-compensation changes |
| Fourth | January 15, 2027 | Year-end results, remaining balance, and filing timing |
Use a New Jersey-specific projection
Estimate New Jersey income, exemptions, deductions, tax, credits, withholding, and payments already made. A pass-through business alternative income tax credit, prior-year overpayment, nonresident payment, or other state item can affect the balance available to apply.
Recalculate the remaining installments after a meaningful change in income, deductions, credits, withholding, residency, or source-state allocation. Do not assume that the federal safe-harbor percentages or a federal annualized calculation produce the New Jersey result. Review the current NJ-1040-ES and, when applicable, current underpayment instructions.
Choose the correct New Jersey payment type
New Jersey's payment system accepts electronic check and card payments, and the current NJ-1040-ES voucher can be mailed. Card processing may involve a fee. Identify the payment as an estimate for the correct tax year and the correct resident, nonresident, or fiduciary account.
An estimated-tax voucher should not be used to pay a prior-year return balance or a notice. Preserve the payment confirmation and check that it posts before sending a duplicate.
