New Jersey State Tax Calculator (2026)

How New Jersey taxes income

New Jersey charges 1.4% to 10.75%. State tax is a separate calculation from your federal return rather than a share of it — New Jersey sets its own schedule and its own definition of taxable income.

• Top marginal rate: 10.75% above $1 million
• Standard deduction: None — New Jersey uses exclusions instead
• Personal exemption: $1,000 single / $2,000 joint, plus $1,500 per dependent
• Bracket structure: Single and joint schedules genuinely differ, not simply doubled

Rate figures are as of January 1, 2026 and come from the published Tax Foundation compilation; they have not been independently checked against New Jersey Division of Taxation. States do change rates mid-year, so confirm a figure there before relying on it.

What catches people out in New Jersey

• New Jersey does not conform closely to the federal definition of income. Contributions and deductions that reduce your federal taxable income — including some retirement contributions — may not reduce New Jersey income, which is why your state taxable income can exceed your federal figure.
• New Jersey and New York have no reciprocity agreement. Commuters file in both states and rely on the resident credit rather than being exempted from one.
• The credit for tax paid to another state is limited to what New Jersey would have charged on that income. Where New York tax is higher, the excess is not recovered.
• New Jersey does not allow a deduction for capital losses against ordinary income in the way federal rules do, and treats several investment items differently. Investment income is worth reviewing separately rather than carrying the federal numbers across.

What this estimate leaves out

Three things are deliberately outside this calculation, because they change more often than annually and a confident wrong number does real damage on a tax page.

• The personal exemption — $1,000 single, $2,000 joint, $1,500 per dependent — is not applied, so the figure runs slightly high.
• Local and city income tax is not included. New York City is the significant one nationally.
• State-specific credits, subtractions and income addbacks are out of scope and can move the result either way.

If you have income in India, New Jersey is where treaty relief runs out

States are not parties to the India-US tax treaty, and a state credit for "taxes paid to other jurisdictions" almost always means other US states rather than other countries.

So NRO interest, Indian rental income or a gain on Indian shares can be taxed by New Jersey with no credit for the Indian tax deducted at source — even though Form 1116 largely neutralises that same tax federally.

The treatment is not uniform across states, and it has been verified individually rather than assumed. The state guide sets out this state's position with the primary source behind it.
