File Your Tax Return Now →New Hampshire Residents: No Personal State Income Tax (Tax Year 2025 Onward)
New Hampshire eliminated its Interest & Dividends (I&D) Tax effective January 1, 2025. For Tax Year 2025 and beyond, New Hampshire imposes no personal income tax of any kind – no tax on wages, salaries, or investment income. If you are filing for Tax Year 2025, you have no New Hampshire state return to file, no state extension to request, and no state payment to make. Federal income tax obligations still apply.
No NH Return Required
New Hampshire has no personal income tax as of Tax Year 2025. No state return, no state extension, and no state payment are required.
Federal Deadline: April 15, 2026
Federal income tax still applies. File IRS Form 4868 by April 15, 2026, if you need an automatic extension to October 15, 2026.
I&D Tax Repealed – No State Extension Process Exists
New Hampshire’s Interest & Dividends Tax was fully repealed effective January 1, 2025, under legislation signed by Governor Chris Sununu. For Tax Year 2025, there is no state extension form, no state payment portal, and no New Hampshire agency to contact regarding a state income tax filing. Your New Hampshire state compliance is automatically satisfied.
How to Extend Your Federal Return
New Hampshire residents who need more time to file their federal return follow the same process as taxpayers in any other state:
- ✓Collect your income documents – W-2s, 1099s, and any other relevant records.
- ✓File IRS Form 4868 electronically or by mail before April 15, 2026.
- ✓Pay any estimated federal taxes owed by April 15 to stop interest and penalties from accruing.
- ✓File your completed federal return by October 15, 2026.
No State Penalties Apply
Since New Hampshire no longer imposes a personal income tax for Tax Year 2025, there are no New Hampshire failure-to-file or failure-to-pay penalties. All penalty risk sits at the federal level. Paying your federal balance in full by April 15 eliminates the IRS failure-to-pay penalty entirely.
Best Practices
- ✓No state action needed – New Hampshire has no personal income tax for Tax Year 2025.
- ✓File IRS Form 4868 by April 15, 2026, if you need more time for your federal return.
- ✓Pay any federal balance due by April 15 to avoid IRS interest and penalties.
- ✓Use IRS Direct Pay for fast, free federal payments with same-day confirmation.
- ✓Set a reminder to file your federal return by October 15, 2026.
New Hampshire’s repeal of the Interest & Dividends Tax removes all state filing complexity for Tax Year 2025 and beyond. Your only obligation is federal – and if you need more time, a quick Form 4868 filing before April 15 gets you to October 15 automatically.
