New Hampshire Personal Tax Extension Guide

New Hampshire's Automatic Extension

New Hampshire does not impose a general personal income tax on wages or salaries. However, New Hampshire does tax interest and dividends income, and taxpayers with a liability under this tax can receive an automatic extension to October 15, 2026. No form or application is required, provided 100% of the tax owed is paid by the original due date of April 15, 2026.

100% Payment Required by April 15

Unlike most states that allow partial payment thresholds, New Hampshire requires 100% of the interest and dividends tax liability to be paid by April 15, 2026, to qualify for the automatic extension. Any unpaid balance after April 15 will be subject to penalties and interest.

How to Make Extension Payments

• Online (Granite Tax Connect): Make extension payments at gtc.revenue.nh.gov/TAP. Both credit card and ACH debit are available.
• Mail: Use Form DP-59-A and mail to NH DRA, P.O. Box 1265, Concord, NH 03302-1265.

Late Filing and Payment Penalties

New Hampshire's failure-to-file penalty is the greater of $10 or 5% per month, up to 25%. The failure-to-pay penalty is a flat 10% of unpaid tax. Full payment by April 15 avoids both.

Best Practices

• Pay 100% of your NH interest and dividends tax by April 15, 2026—no partial payment qualifies.
• Use Granite Tax Connect at gtc.revenue.nh.gov/TAP for online payments.
• File your return by October 15, 2026.

Final Thoughts

New Hampshire's extension applies only to the interest and dividends tax. Pay 100% by April 15 using Granite Tax Connect and file your return by October 15, 2026.
