Hawaii Sales Tax Guide: Rates, Rules & Filing Guide

Hawaii Sales Tax at a Glance

Hawaii does not have traditional sales tax. Instead, the state levies a General Excise Tax (GET) of 4% on almost all gross business income. An additional county surcharge of 0.5% brings the total GET for most transactions in Hawaii to 4.5%. Unlike sales tax, GET is legally owed by the business, not the customer, though most businesses choose to pass on the cost to customers.

The GET applies to most transactions in the state, including SaaS, digital goods, services, physical products, rent, and commissions. If your company has nexus and sells into Hawaii, there’s a good chance GET applies to your business. 

This guide walks through what Hawaii GET is, how it applies to SaaS and other product categories, when you need to register, how to calculate and file returns, and what makes Hawaii's annual reconciliation different from most states.

Taxable Categories: What Hawaii's GET Applies To

Tangible Personal Property (TPP)

Physical goods sold at retail in Hawaii are subject to GET at the 4.5% combined rate. Unlike many other states, Hawaii doesn’t exempt items like groceries, clothing, or prescription drugs. This can make the broad scope of Hawaii GET surprising for businesses that sell items that are generally tax exempt in other states.

SaaS and Digital Products

SaaS and other digital products are taxable in Hawaii. GET applies to software subscriptions, digital downloads, and remotely accessed software just as it applies to any other transaction. 

Hawaii also doesn’t distinguish between business and personal use when it comes to SaaS. Both types of transactions, no matter the customer, are taxable at the combined rate. If your company sells SaaS or digital goods into Hawaii, you most likely need to comply with Hawaii GET.

Unsure when to charge this unusual tax? Sphere's tax engine automatically classifies Hawaii transactions and applies the correct GET rate, so you don't have to manually track which of your product lines are in scope.

Services

Services are another area where Hawaii’s GET varies significantly from sales tax in other states. GET applies to services broadly, including professional fees, consulting, legal work, accounting, repair services, construction, commissions and personal services. 

Most states exempt these types of services, but not Hawaii. If your business sells services into Hawaii, you should assume you’re on the hook for GET unless confirmed otherwise. 

Monitoring: When Hawaii's GET Applies to You

Economic Nexus Threshold

Remote sellers into Hawaii trigger economic nexus when they make $100,000 in gross income or complete 200 or more transactions in the state in the current or preceding calendar year.

Every sale counts toward this threshold, whether taxable or non-taxable. Once you cross either number, your business is required to register for Hawaii GET and start collecting. 

Sphere monitors your Hawaii sales activity automatically and flags you before you approach the threshold, so nexus never catches you off guard.

Physical Nexus

Any physical presence in Hawaii creates sales tax nexus regardless of your revenue. This includes having an office, employees, inventory, or even providing services like installation, training, maintenance, or repair work in the state. Physical nexus doesn't require hitting a dollar threshold.

Marketplace Facilitators

If you sell through a marketplace platform, that platform is generally responsible for collecting and remitting GET on your behalf. That said, marketplace-only sellers may still have a separate filing obligation depending on their overall activity in the state, so don't assume you're fully off the hook just because you sell through a marketplace. For example, if you sell through Amazon but also through your own online store, you’re still responsible for GET on your store’s sales.

Registration: How to Register for Hawaii GET

How to Register

You register for the GET through Hawaii Tax Online (hitax.hawaii.gov) by completing Form BB-1, the State of Hawaii Basic Business Application. If you apply online, the state typically issues your Hawaii Tax ID immediately. In-person applications at a district tax office are processed the same day, and mailed applications can take up to four weeks.

Once you're registered, your GET license needs to be displayed at your place of business.

Registration Fees

Registration costs a one-time fee of $20. There's no additional fee for a duplicate license if you lose yours, but if your license is ever cancelled, you'll need to submit a new application and pay the $20 fee again to reopen it.

Sphere and Registration

Sphere manages the full BB-1 registration process for you, including setup in Hawaii Tax Online, so you don't have to navigate the state's registration portal yourself.

Calculation: Hawaii GET Rates

Standard and Reduced Rates

The standard combined Hawaii GET rate is 4.5%. This is 4% at the state level plus a 0.5% county surcharge in every county. This applies to retail sales, services, SaaS, and most other business activities.

You can pay this tax out of pocket, but most businesses choose to pass it on to customers. If you choose to pass the tax on to customers, the maximum pass-on rate is 4.712% across all four counties. This slightly higher rate accounts for the fact that the passed-on amount itself becomes part of your taxable gross income.

‍

But not all transactions are taxed the same. A reduced rate of 0.5% applies specifically to wholesaling, manufacturing, and producing goods sold for resale. The county surcharge doesn't apply at this reduced rate. There's also a special 0.15% rate that applies only to insurance commissions.

What the Rate Applies To

The GET applies to gross income from nearly all business activities including retail sales, SaaS, digital goods, services, rent, commissions, and contracting. There's no exemption for sales to nonprofits or government entities either. Since the tax is imposed on the seller rather than the buyer, even sales to tax-exempt nonprofits are generally subject to GET, though you can still choose to pass the cost on to these customers. 

Filing: How and When to File Hawaii GET Returns

Filing via Hawaii Tax Online

File GET returns electronically through Hawaii Tax Online using Form G-45, the periodic return, and Form G-49, the annual reconciliation. Note that even if you had zero taxable activity during a filing period, you still need to file a return showing zero.

Filing Deadlines

Periodic returns are due on the 20th day of the month following the close of your filing period. A monthly filer reporting January activity owes their return by February 20. A quarterly filer reporting the January through March period owes their return by April 20.

Hawaii also requires an annual reconciliation. Form G-49, the annual reconciliation, is due on the 20th day of the fourth month after your taxable year closes. For calendar year filers, that means April 20 of the following year.

The Annual Reconciliation: What Makes Hawaii Different

Every Hawaii GET filer has to submit Form G-49 once a year, no matter how often they file periodic returns. This is in addition to your periodic G-45 filings, not a replacement for them.

Form G-49 summarizes your entire year of activity and reconciles it against what you reported periodically. It's also your chance to correct any errors or claim exemptions you missed on a periodic return. Filing your annual return is also what starts the state's three-year statute of limitations clock. If you miss filing this return, the Department of Taxation can go back and adjust your return at any time.

This annual reconciliation is easy to overlook if you’re used to filing periodic sales tax in other states. But if you don't file it within 12 months of its due date, you risk losing the right to claim GET exemptions and deductions, so it’s vital to file this form.

Sphere handles both your G-45 periodic filings and the G-49 annual reconciliation automatically, so nothing falls through the cracks.

Filing Frequency Thresholds

How often you file periodic returns depends on how much GET you owe in a year, not on your revenue directly.

‍

It’s important to note that your total annual GET, use tax, and county surcharge liability exceeds $100,000, you're required to remit payment by electronic funds transfer (EFT). If your annual GET liability exceeds $4,000, your G-49 annual return must also be filed electronically. Missing either of these electronic requirements triggers a 2% penalty on your total tax due.

Late Filing Penalties

Filing late costs 5% of the tax due per month or partial month, up to a maximum of 25%.

If you file on time but don't pay within 60 days of the due date, the state adds a 20% penalty on the unpaid tax.

Failing to pay by EFT when required adds a separate 2% penalty on your total tax.

On top of all that, interest accrues at 2/3 of 1% per month on any unpaid taxes and penalties, starting the day after your due date.

Remittance: How to Pay Hawaii GET

Remittance via Hawaii Tax Online

Payments are typically made by ACH debit from a US bank account through Hawaii Tax Online at the time you file. As noted above, businesses with more than $100,000 in combined annual tax liability are required to pay by EFT instead.

Remittance for Foreign Businesses

If your business doesn't have a US bank account, paying the GET through Hawaii Tax Online isn't straightforward. Sphere's embedded remittance platform handles GET payments on your behalf, so you can stay compliant in Hawaii without needing to open a local bank account.

How Sphere Helps With Hawaii GET Compliance

Sphere monitors your Hawaii economic nexus exposure and lets you know when you're approaching the $100,000 or 200-transaction threshold, well before registration becomes urgent.

From there, Sphere handles your BB-1 registration, applies the correct GET rate to every transaction (whether that's the 4.5% standard rate, the 0.5% wholesale rate, or the 0.15% insurance commission rate), and files both your periodic G-45 returns and your annual G-49 reconciliation on schedule. 

And if you're a foreign business without a US bank account, Sphere's embedded remittance platform takes care of payment so a missing bank account never becomes a compliance gap.
