HI — HawaiiHawaii Personal Income Tax Extension — What You Need to Do
Hawaii grants an automatic six-month extension of your personal income tax filing deadline to October 20, 2026 — with no form to file. You receive the extension automatically as long as you pay 100% of your Hawaii tax liability by April 20. To make an extension payment, use Form N-200V or pay online at Hawaii Tax Online. Any Hawaii tax you owe is due April 20 — penalties and interest run from that date on any shortfall.
Hawaii Extension Checklist — 2026
Three things to handle. One deadline that drives them all.
Secure Your Extension
For your federal return, file a federal extension (IRS Form 4868). Hawaii’s extension to October 20 is automatic and needs no form — but only if you pay 100% of your Hawaii tax by April 20. To pay, use Form N-200V or Hawaii Tax Online.
Pay 100% of Your Hawaii Tax
Hawaii’s automatic extension requires you to pay 100% of your tax liability by April 20 — a shortfall voids the extension. A failure-to-pay penalty (up to 20%) plus interest apply to any unpaid balance from April 20. Pay in full by April 20.

Hawaii Late Penalties — What It Costs to Wait
A valid extension gives you until October 20 to file. But unpaid tax starts accruing penalty and interest the day after April 20.
| Penalty Type | Rate | Cap | Trigger |
|---|---|---|---|
| Failure to Pay | Up to 20% | 20% | Tax not paid in full by April 20 (voids extension) |
| Failure to File | 5% per month | 25% | Return filed late / extension conditions not met |
| Interest | 2/3 of 1% per month | No cap | Accrues on unpaid tax from April 20 |

Hawaii Tax Extension — Frequently Asked Questions
Do I need to do anything to get the Hawaii extension?
Hawaii’s extension is automatic — there is no form to file. You qualify as long as you pay 100% of your Hawaii tax liability by April 20, 2026, file your return by October 20, 2026, include any remaining balance, and are not under a court order to file earlier. Missing any condition voids the extension.
What is Form N-200V?
N-200V is Hawaii’s Individual Income Tax Payment Voucher. Use it to send an extension payment by mail so it’s properly credited. There is no separate extension application — the extension is automatic if you pay 100% of your tax by April 20.
Does the Hawaii extension cover my federal return?
No. Hawaii’s automatic extension only covers your Hawaii return. For more time on your federal return, file IRS Form 4868 separately with the IRS.
What if I can’t pay my full Hawaii tax by April 20?
Pay as much as you can — but note that not paying 100% by April 20 voids your automatic extension. A failure-to-pay penalty (up to 20%) plus interest apply to the unpaid balance, so every dollar paid by April 20 lowers your total and protects your extension.
Which Hawaii return form do I need?
Form N-11 is for full-year residents. Form N-15 is for nonresidents and part-year residents. Both are due by the extended deadline of October 20, 2026.
How do I pay my Hawaii extension tax online?
Pay through Hawaii Tax Online at hitax.hawaii.gov by electronic bank debit or credit card. Note that Hawaii charges a service fee for both online payment methods. For mailed payments, use Form N-200V.
