New Hampshire Filing Due Date: The State of New Hampshire does not impose a personal income tax, but it does have an Interest and Dividends (I&D) Tax. The I&D Tax applies to individuals and fiduciaries with gross interest/dividends income above a certain level. I&D tax returns are due by April 15, in most years — or by the 15th day of the 4th month following the end of the taxable year (for fiscal year filers).
Extended Deadline with New Hampshire Tax Extension: New Hampshire offers a 7-month extension, which moves the I&D filing deadline from April 15 to November 15 (for calendar year filers).
New Hampshire Tax Extension Form: To request a New Hampshire I&D tax extension, file Form DP-59-A by the original due date of your return.
Note that Form DP-59-A does not have to be filed if you owe zero New Hampshire I&D tax for the taxable year. In that case, you will automatically be granted a NH tax extension.
New Hampshire Extension Payment Requirement: An extension of time to file is not an extension of time to pay your New Hampshire I&D tax. All state tax payments are due by the original deadline of the return (April 15). Any tax that isn’t paid by the proper due date will be subject to interest and penalties. You can make an extension payment for your I&D tax with Form DP-59-A, or pay electronically through e-File New Hampshire: www.efilenh.govconnect.com
New Hampshire Tax Extension Tip: If 100% of your I&D tax is paid on time (April 15), you will receive an automatic New Hampshire extension. In this case, you do not need to file Form DP-59-A.
