The app combines calculators, quick reference guides, deadline reminders, and official resource links in one clean place, making everyday tax planning easier to follow.
For tax year 2025, New Jersey uses graduated individual income tax rates, with schedules reaching 10.75% at the top end. New Jersey also has a single statewide sales and use tax rate of 6.625% with no local add-ons. Most calendar-year 2025 federal and New Jersey individual returns are due April 15, 2026. If you qualify for an extension and have paid at least 80% of the tax due by April 15, the New Jersey extended filing deadline is October 15, 2026.
