Hawaii GET filing software (August 2026)

Official · free e-file

File on HITAX / Hawaii Tax Online

The State of Hawaii’s own site is the official way to e-file GET. There is no software subscription.

You file Form G-45 (periodic) and Form G-49 (annual) yourself. This is the right path if you can sit down on the 20th.

Paper is still allowed for some filers. Monthly filers — expected annual GET over $4,000 — must e-file on Hawaii Tax Online.

GET is not a sales tax

It is a tax on the business. A business may pass the cost on, but does not have to. If it does, that amount is still part of gross receipts.

People often say “Oahu 4% + 0.5%.” Use the official wording: 4.5%* for retail goods and services, renting, leasing real property, construction contracting, commissions, and all others. The asterisk is the 0.5% county surcharge.

The surcharge does not apply to the 0.5% wholesale/producing rate or the 0.15% insurance-commission rate.

Official rates, due dates, and the license

County surcharge

0.5%
all four counties

The county surcharge page lists 0.5% in Honolulu, Kauai, Hawaii, and Maui through December 31, 2030.

Maximum pass-on printed there for the current 0.5% period: 4.7120%.

Form G-45

Due the 20th after the period ends. If the 20th is a weekend or holiday, the next business day. The official GET page does not list an extension.

Frequency comes from expected annual GET liability:

Semi-annual if ≤ $2,000 (example: January–June due July 20)
Quarterly if ≤ $4,000 (example: January–March due April 20)
Monthly if > $4,000 (example: January due February 20). Monthly filers must e-file on Hawaii Tax Online.

Zero returns are still required.

Form G-49

Due the 20th of the fourth month after year-end. Calendar-year filers: April 20.

License and penalties

License: Form BB-1, one-time $20. Extra locations or trade names: Form G-50, no extra charge on the official page.

DOTAX prints late-file, late-pay, interest, e-file, and Part V penalties on the GET page; read them there.

$29–$149/mo on the main pricing page, plus a filing add-on

Filing is not in the main pricing table. Their TaxJar-alternatives page prints US state filing at $70 per state per month, no setup fee, no long-term commitment. That is the source for the filing price. This page did not re-fetch a Cloudflare-gated support article.

Date mismatch — do not use Quaderno’s January 20 Their Hawaii guide still says annual GET is due January 20. Official G-49 for a calendar year is April 20. Their guide lists frequency as monthly, quarterly, or annually. Official frequency is monthly, quarterly, or semi-annual.
