Hawaii sales tax rates 2026: Calculator, nexus, and due dates

Hawaii sales tax rates by city and county

Hawaii’s tax structure is county-based, not city-based. The 4% GET applies statewide. Counties may adopt a surcharge of up to 0.5% on top of the 4% rate. The current county surcharge is 0.5% in the counties that have adopted it, but effective dates vary by county — for example, Hawaii County’s surcharge was 0.25% before moving to 0.5% on January 1, 2020. Check the Department of Taxation’s county surcharge page for current rates and effective dates. The county surcharge applies only to activities taxed at the 4% rate — it does not apply to wholesale (0.5%) or insurance commission (0.15%) activities.

Because Hawaii is a destination-based state, you charge the rate based on where the customer receives the product or service. All GET returns are filed with the Hawaii Department of Taxation — there are no separate county filings.

Hawaii nexus thresholds

Remote sellers and businesses with a physical presence in Hawaii are subject to GET nexus laws. You are required to register and collect GET if you trigger “nexus” through a physical presence in the state or by exceeding specific economic thresholds.

Hawaii economic nexus

You will trigger Hawaii economic nexus if you exceed either of the following thresholds in the current or previous calendar year:

• Sales threshold: $100,000 in gross income or gross proceeds from sales of tangible personal property, services, or intangible property delivered or used in Hawaii (including marketplace sales).
• Transaction threshold: 200 or more separate transactions.

Hawaii uses an “or” standard — exceeding either threshold triggers nexus. Unlike most states, marketplace sales are included in a seller’s threshold monitoring. Once nexus is triggered, the seller must register and follow Hawaii’s GET filing and collection rules as required by the Department of Taxation.

Hawaii physical nexus

Businesses with a physical presence in Hawaii have GET registration and collection obligations. Physical nexus triggers include:

• Inventory: Storing goods in a warehouse, 3PL, or Amazon FBA fulfillment center in Hawaii.
• Personnel: Employees, contractors, sales reps, or agents conducting business in Hawaii.
• Property: Maintaining an office, storefront, or other place of business in Hawaii.

Hawaii sales tax permit registration

Once you trigger nexus, you must register with the Hawaii Department of Taxation before you can legally collect GET.

Operating without a GET license after crossing the threshold exposes you to back taxes, penalties, and interest from the date nexus was established — not the date you registered.

1. Gather your information. You’ll need your FEIN, estimated sales, business structure details, and bank account information.
2. Submit your application. Complete Form BB-1 (State of Hawaii Basic Business Application) through Hawaii Tax Online and pay the one-time $20 registration fee. Online applications receive a Hawaii Tax ID within 5–7 days.
3. Note your effective date. Once nexus is triggered, the seller must register and comply with Hawaii’s filing and collection rules as required by the Department of Taxation. If there’s a gap between crossing the threshold and registering, you may owe back taxes for that period.

If you have questions about your Hawaii registration or compliance history, TaxCloud’s U.S.-based support team typically responds within 2 hours and can review your setup directly.

Hawaii sales tax calculation rules

Hawaii’s GET is fundamentally different from a traditional sales tax. It is imposed on the business’s gross receipts — not on the consumer — and it applies to virtually all business activities, including services and B2B transactions. This makes Hawaii’s tax base one of the broadest in the U.S.

What is taxable in Hawaii?

Taxability in Hawaii is determined by the nature of the business activity. Because GET applies to gross receipts from virtually all business transactions, Hawaii’s tax base is significantly broader than most states. Below is a high-level summary of how major categories are generally treated for 2026:

• Tangible personal property: Most physical goods — such as furniture, electronics, and standard retail items — are subject to the 4% GET plus the applicable 0.5% county surcharge unless a specific exemption applies.
• SaaS, software, and digital products: Many SaaS, software, and digital-delivery receipts are taxable under Hawaii GET, depending on the underlying business activity and applicable district rules. This generally includes prewritten software, custom software, and digital goods such as eBooks, music, movies, and streaming services.
• Food & groceries: Hawaii taxes food and food ingredients under GET. There is no exemption for grocery staples. Prepared food is also taxable.
• Clothing: Clothing and footwear are taxable at the standard GET rate.

What is tax exempt in Hawaii?

Below is a high-level summary of items that are generally exempt from GET in Hawaii:

• Essential exemptions: Hawaii provides specific exemptions for items such as prescription drugs and prosthetic devices.
• Additional exemptions: Sales for resale (taxed at the reduced 0.5% wholesale rate rather than exempt), certain amounts received by nonprofit organizations, and specific agricultural products. Hawaii also exempts certain amounts received under government contracts.

Hawaii sales tax return due dates and filing frequency

In Hawaii, periodic GET returns (Form G-45) are due on the 20th of the month following the reporting period. The Hawaii Department of Taxation assigns filing frequency — monthly, quarterly, or semi-annual — when you register.

The annual reconciliation return (Form G-49) is required for all filers regardless of their periodic filing frequency. It reconciles GET for the full tax year and is due on the 20th day of the fourth month following the close of the taxable year.

Critical 2026 compliance notes:

• GET is not a consumer tax: Unlike a traditional sales tax, GET is imposed on the business. Businesses may pass the tax on to customers but are not required to do so. If passed on, the maximum pass-on rate is 4.712% (which accounts for the tax-on-tax effect of GET being assessed on the amount passed to the customer).
• Zero-return requirement: If you are registered but had $0 in gross income this period, you must still file. Hawaii assesses a late filing penalty of 5% of tax owed per month (capped at 25%), plus ⅔ of 1% per month interest.
• Electronic filing: Hawaii Tax Online (hitax.hawaii.gov) is the primary filing portal. Form G-45 is used for periodic returns and Form G-49 for annual reconciliation.
• Weekend/holiday rule: If the 20th falls on a weekend or state holiday, your return is due the next business day.
