If you're registered for Hawaii General Excise Tax (GET), you must file periodic returns on Form G-45 and an annual reconciliation on Form G-49. Unlike traditional sales tax imposed on the buyer, GET is a privilege tax on the right to do business in Hawaii, and it is the seller's obligation to file and remit it. This guide covers G-45 filing frequencies, due dates, the G-49 annual return, payment options, and the Oahu surcharge for remote sellers and out-of-state businesses using Hawaii Tax Online.
For broader information about Hawaii GET rules, rates, and exemptions, see the Hawaii Sales Tax Guide. For details on how to get a Hawaii GET license, see the Hawaii GET Registration Guide.

When to file and pay Hawaii GET
The Hawaii Department of Taxation will assign you a G-45 filing frequency (monthly, quarterly, or semi-annually) after you register your business, based on your total annual GET liability.
Hawaii GET returns and payments are due at the same time, by the 20th of the month following the end of the filing period. If the 20th falls on a weekend or holiday, the due date shifts to the next business day.

Zero returns required
Once you have a Hawaii GET license, you must file a G-45 return for every assigned period regardless of whether any business activity occurred or GET was collected. When no GET was due, file a zero return electronically through Hawaii Tax Online.
Form G-49: Annual reconciliation return
All GET taxpayers must file Form G-49 annually, regardless of their G-45 filing frequency. The G-49 reconciles your full-year gross receipts, deductions, and total tax owed against the payments already made on your G-45 periodic returns. If you overpaid across your G-45 returns, the G-49 generates a refund or credit; if you underpaid, the balance is due with the return.
The G-49 is due on the 20th day of the 4th month after the end of the tax year. For calendar-year filers, that is April 20.
The Oahu surcharge
If any of your sales are sourced to Oahu (the City and County of Honolulu), you must track those transactions separately and apply the additional 0.5% surcharge. The combined rate on Oahu is 4.5% (4% GET plus 0.5% surcharge).
The surcharge is reported on a separate schedule within your GET return filed through Hawaii Tax Online. You do not need to file a separate return for the surcharge, but you must report Oahu-sourced sales distinctly from sales sourced to the other Hawaiian islands.
How to prepare your Hawaii GET return
Before filing, gather your business activity records for the period. Because GET applies to most business activities, you generally include all revenue from Hawaii customers, not just retail sales. You will need:
- Total gross income from all Hawaii business activity
- Income sourced to Oahu (for surcharge reporting)
- Allowable deductions and exemptions
- Total GET owed at 4% statewide
- Total Oahu surcharge owed at 0.5% on Oahu-sourced income
How to complete and file a Hawaii GET return
Hawaii GET returns are filed electronically through Hawaii Tax Online (HTO) and must be reported in US dollars.
Step-by-step: file a Hawaii GET return
1. Log in and open your return
- Log in to Hawaii Tax Online (HTO).
- Navigate to your General Excise Tax account.
- Select the filing period you want to file.
- Enter your gross income, deductions, Oahu-sourced amounts, and total GET owed.
- Complete the Oahu surcharge schedule if applicable.
- Review and submit your return.
2. Save your confirmation
After submitting, you will receive a confirmation number. Save it as your record of filing.
How to pay Hawaii GET
Hawaii requires most businesses to file and pay electronically through Hawaii Tax Online. You can pay directly within the portal after filing your return. Accepted payment methods include:
- Electronic funds transfer (direct bank payment)
- Credit card (fees may apply)
What happens after filing and paying Hawaii GET
Save your confirmation number and payment receipt as your record of filing. Keep records supporting all reported income and deductions in case of a future audit.

Late filing penalties and interest
If you miss a Hawaii GET filing deadline, file as soon as possible. Failure to file returns and remit GET on time results in penalties and interest charges that increase the longer you wait.
For current penalty rates and interest charges, refer to the Hawaii Department of Taxation website.
