Hawaii General Excise Tax for Small Business: The 2026 Guide

Most Hawaii business owners treat the GET like a sales tax. Collect 4.5% from the customer, hand it to the state, move on. That's not how it works and the gap between what most owners believe and how GET actually operates quietly costs Hawaii businesses thousands of dollars every year.

GET is a tax on doing business. Every dollar that comes into your business is subject to it — not your profit, not what's left after expenses. Gross revenue. All of it. In 2025, the Hawaii Department of Taxation collected $4.6 billion in GET revenue — a 3.3% increase from the prior year. It is the state's largest revenue source. And it operates in a way that nothing on the mainland quite prepares you for.

This guide covers everything a Hawaii small business owner needs to know about the general excise tax: what it is, what rate you pay, how to register and file, how to pass it on correctly, and how to set your books up so compliance doesn't become a cash flow crisis.

What Is Hawaii's General Excise Tax (GET)?

GET Is a Privilege Tax, Not a Sales Tax

Hawaii's general excise tax is a tax on the privilege of doing business in Hawaii. The state taxes your business for the right to operate — not your customers for the right to buy. That distinction matters because it changes who's responsible and what gets taxed.

Here's the core rule: GET applies to your gross business receipts. Every dollar your business receives is potentially subject to GET. If you sold $500,000 in services last year and spent $400,000 running the business, GET still applies to the full $500,000. You owe 4% on $500,000 — not on your $100,000 margin. That surprises most people who come from a sales tax state.

In most states, sales tax is calculated on the transaction and collected from the buyer. The seller is just the collection agent. In Hawaii, the tax is on the seller and calculated on total receipts — whether you collected extra from customers to cover it or not.

If you moved your business from the mainland to Hawaii — or started a business here — the GET is almost always the first tax surprise. And it's usually not a small one.

Takeaway: GET is applied to everything that comes in, not what's left over. Plan your pricing and your banking with that in mind from day one.

How Is Hawaii GET Different from a Regular Sales Tax?

There's no general sales tax in Hawaii. Many tourists and some new business owners assume that means there's no consumption tax — which leads to compliance surprises later. There is a tax. It's just structured differently and borne by the business rather than the buyer.

With a traditional sales tax, the seller acts as a collection agent. The state taxes the consumer, you collect it at point of sale, and send it in. The money is never yours. With GET, the state taxes the business directly. You owe it on every dollar of revenue whether you passed the cost along to your customers or not — and the amount cannot be backed out of your receipts as "already collected."

GET also applies to services, not just goods. A plumber in Phoenix might not charge sales tax on labor. A plumber in Honolulu owes GET on every service dollar billed. This applies to consultants, designers, attorneys, accountants, personal trainers — anyone providing services in Hawaii.

Finally, GET cascades through B2B transactions in a way that sales tax doesn't. When two Hawaii businesses transact, GET applies at every level. This is what the SBA documented in a 2019 study as a structural disadvantage for Hawaii's local small businesses — mainland competitors ship goods to Hawaii without multi-layer GET exposure, while local businesses pay at each step of the chain. It's a real cost that most Hawaii business owners absorb without fully understanding why their margins are tighter than they expect.

Takeaway: GET isn't a passthrough tax. It's your tax, on your revenue, whether you collect it from customers or absorb it yourself. Services are taxed. B2B transactions are taxed. The playbook from a sales tax state doesn't apply here.

Hawaii GET Tax Rates in 2026: What Rate Does Your Business Pay?

The Base Rates

Hawaii's GET uses a tiered rate structure. Most small businesses land in the 4% category, but the rate depends on your activity type.

If you run a service business — consulting, contracting, food service, professional services, anything — you're at 4% on gross receipts. The wholesale and manufacturing rates require specific documentation (a valid resale certificate from your buyer) to apply.

County Surcharges: All Four Islands Now at 4.5%

Every county in Hawaii now adds a 0.5% surcharge on top of the base rate for most business activities. As of January 1, 2024, all four counties are aligned.

The Maui county surcharge change in 2024 is one of the most frequently missing updates in competitor content. Many guides still show Maui at 4%. If your business operates on Maui and hasn't updated GET filings to reflect the 0.5% surcharge since January 2024, review those returns.

One practical note for businesses operating across islands: the rate that applies is determined by where the sale or service is performed, not where your business is incorporated or your office is located. If you're based on Oahu but do a construction job on Maui, Maui's rate applies to that work.

Takeaway: All four Hawaii counties are now at 4.5% for most activities. If you do business on multiple islands, track revenue by location — the rate follows the work, not the headquarters.

Who Has to Pay Hawaii GET? (The Answer May Surprise You)

The short answer: most Hawaii businesses. The GET is broader than most people expect, and the list of who's covered goes well beyond brick-and-mortar retail.

Who Must Register and Pay

You're required to register for a GET license and pay GET if you:

• Own a business selling goods or providing services in Hawaii
• Are self-employed or a freelancer earning income from Hawaii clients (this includes photographers, designers, coaches, consultants, writers)
• Earn rental income in Hawaii — residential or commercial
• Are an independent contractor paid for services in Hawaii
• Operate an online business with economic nexus in Hawaii — more than $100,000 in Hawaii sales or 200 separate transactions per calendar year
• Are an out-of-state business physically performing services in Hawaii

A freelance graphic designer working from a Kailua studio owes GET on every invoice she sends. A Maui tour operator owes GET on every booking. A Honolulu landlord owes GET on every rent check. A Kona photographer who shoots weddings for visiting couples owes GET on every session. The coverage is genuinely broad — and it catches people who assumed they were too small or too informal to matter to the state.

Who Is Typically Exempt

The exemptions are narrower than most people hope. Certain agricultural businesses — sale of specific livestock and farm products — qualify. Licensed wholesalers buying for resale pay at the lower wholesale rate, not retail. Certain nonprofit organizations have limited exemptions on specific activities.

Even nonprofit customers don't exempt the seller from GET. The tax is on the seller, and the buyer's tax status is irrelevant. If you're unsure whether your business qualifies for an exemption, assume you don't. Registering, filing, and then confirming your status with a Hawaii tax professional is cheaper than operating without a license and discovering years of back liability.

Takeaway: GET reaches freelancers, landlords, contractors, online sellers, and out-of-state businesses with Hawaii customers. If money is coming into your business from Hawaii sources, assume GET applies until you can confirm otherwise.

How to Get Your Hawaii GET License (It's Easier Than You Think)

Register before your first dollar of revenue. We see this regularly — a client launches, operates for six, twelve, sometimes eighteen months without a GET license, then receives a DOTAX notice. The back tax liability, plus penalties and interest, is almost always far larger than the cost of registration would have been. There is no grace period for revenue you earned before you registered.

Registration is straightforward:

1. Complete Form BB-1 (Basic Business Application). This is the same form used to register for multiple Hawaii business tax types at once. Available through Hawaii Tax Online at hitax.hawaii.gov.
2. Pay the $20 registration fee. One-time only. Not annual.
3. Submit online. Online processing through Hawaii Tax Online is fastest — typically 5 to 7 business days to receive your GET license number.
4. Your GET license number begins with "GE-" followed by a numeric identifier. Keep it on file. You'll use it on every return you file.

There is no minimum revenue threshold for registration. If you're operating a business in Hawaii, you register. Display your GET license number at your place of business where customers can see it. For service businesses without a walk-in location, keep it accessible in your records.

Takeaway: Register with Form BB-1 at hitax.hawaii.gov before you earn your first dollar. The $20 registration cost is negligible compared to the back tax exposure of operating without a license.

When and How to File Your Hawaii GET Returns (G-45 and G-49 Explained)

Two Forms, Two Functions

Form G-45 is the periodic return. You file it monthly, quarterly, or semiannually — depending on your annual GET liability. This is where you report gross receipts and calculate the GET owed for each filing period throughout the year.

Form G-49 is the annual reconciliation return. Filed once per year after the filing year closes, it reconciles everything you reported on G-45 returns against your full-year totals. If you overpaid during the year, G-49 is where you get a refund. If you underpaid, it's where you settle the balance.

Filing Frequency

Your filing frequency is determined by your estimated annual GET liability:

For a new business, DOTAX assigns a filing frequency based on your estimated liability at registration. If you're not certain, default to monthly. Filing more frequently than required is never penalized. Filing less frequently than required triggers penalties on missed periods — and they compound fast.

Due Dates

G-45 returns are due on the 20th of the month following the end of the filing period. Monthly filers for March are due April 20. Quarterly filers for Q1 (January through March) are due April 20. G-49 annual returns are due on the 20th day of the fourth month after your fiscal year ends — for most calendar-year businesses, that's April 20.

Zero Returns

If your business had zero revenue in a filing period, you still must file a return. This is called a zero return. Many new business owners stop filing during slow months, assuming nothing to report means nothing to file. DOTAX reads missing returns as non-compliance, not a vacation. The penalty structure applies regardless of whether tax was owed.

Takeaway: G-45 is your periodic filing, G-49 is your annual reconciliation. Mark the 20th of every relevant month in your calendar. Zero revenue does not mean zero filing obligation — the return is always required.

Passing GET On to Your Customers: How to Do It Correctly

You Can Pass It On — But the Math Is Trickier Than It Looks

GET is the business's tax. But Hawaii law explicitly allows you to separately state GET on your invoice and collect it from customers. Most Hawaii businesses do this. The mistake most of them make is treating GET like a standard percentage add-on — and it costs them money on every transaction.

If the GET rate is 4.5% and you add 4.5% to your invoice, the math doesn't work. Once you charge GET to your customer, the amount you collect — including the GET — becomes part of your gross receipts. GET is owed on gross receipts. So if you charged a customer $1,045 ($1,000 + $45), you now owe GET on $1,045, not $1,000. GET on $1,045 at 4.5% = $47.03. But you only collected $45. You're short $2.03 on that one invoice. Multiply that across a year of revenue and it's real money.

The Correct Pass-On Rate

To fully recover GET from your customer so that you net your intended amount, you need to charge 4.712% in any county with the 0.5% surcharge — which is now all four Hawaii counties. This is the number most Hawaii residents recognize as the GET line on receipts.

Here's the math: if you want to net $1,000 from a transaction, you charge the customer enough so that after paying 4.5% GET on the full invoice, you keep $1,000.

Amount to charge = $1,000 ÷ (1 − 0.045) = $1,000 ÷ 0.955 = $1,047.12

The additional $47.12 is 4.712% of $1,000. You remit $1,047.12 × 0.045 = $47.12 to the state. You net $1,000.00 exactly.

Real Example: Honolulu Service Business Invoicing a Client

A Honolulu marketing consultant invoices a client for $2,500 in services and wants to fully pass GET through:

Display the GET as a separate labeled line item on every invoice: "Hawaii General Excise Tax (4.712%)." Do not round up or use a higher percentage — Hawaii consumer protection rules prohibit collecting more GET from customers than the legally calculated amount.

Takeaway: Never add 4% or 4.5% as your pass-on rate. Use 4.712% for all four Hawaii counties and show it as a separate line on your invoice. The math matters — and the difference compounds across a full year of revenue.

GET Exemptions and Deductions: What You Can Reduce

Hawaii's GET has approximately 60 categories of exemptions and deductions in the tax code. Most small businesses encounter only a handful. Here are the ones that actually matter in practice.

Wholesale Transactions and Resale Certificates

If you sell goods to another licensed Hawaii dealer for resale, the transaction is taxed at the wholesale rate — 0.5% rather than 4%. To apply that rate, your buyer must provide you a valid Form G-17 (Resale Certificate). Keep it on file. Without documentation, DOTAX may reclassify wholesale transactions as retail during an audit, which triggers a large retroactive liability.

If you purchase goods from a Hawaii wholesaler for resale, they should be charging you the wholesale rate. Make sure you're providing your G-17 and not being charged retail GET on purchases that qualify.

The Subcontractor Deduction: Construction Industry's Most Important Tool

This is the most significant deduction for Hawaii's construction industry, and it's one most general contractors either underuse or apply incorrectly. When a GC uses licensed subcontractors, the GC can deduct the amounts paid to those subcontractors before calculating GET on their own receipts.

Real example from a Honolulu construction project:

The key requirement: the subcontractor must hold their own valid GET license and pay GET on what they received. The deduction prevents the cascading double-taxation that otherwise runs through the construction chain. Document everything — the subcontractor's GET license number belongs in your records.

What Doesn't Work

You cannot deduct your business expenses — payroll, rent, materials for service businesses, overhead — before calculating GET. Sales to nonprofits don't exempt the seller. Losses from prior periods don't reduce your GET base. GET is on gross receipts in and nothing else reduces that base for most businesses.

Takeaway: The subcontractor deduction is significant for construction. Resale certificates are essential for product businesses. For most service businesses, GET applies to every dollar with minimal deductions available — build that into your pricing from the start.

GET Bookkeeping: How to Set Your Books Up for Compliance

This section exists nowhere else in the GET content landscape. We're including it because it's the practical piece every Hawaii business owner asks about — and because getting the structure right from the start saves significant cleanup cost later.

The Account Structure

When we set up a new client's books in Hawaii, here's the GET account structure we install every time.

Income accounts by GET rate category. Not all revenue is taxed at the same GET rate. If your business earns retail and wholesale income, those need to be tracked in separate income accounts. QuickBooks Online, Xero, and Wave all support this with sub-accounts under your main revenue account. If DOTAX ever audits you, you need to be able to show what portion of your revenue fell under each rate — not reconstruct it from three years of mixed transactions.

A GET Liability account. GET collected from customers is not your revenue. It's a liability — money you're holding on behalf of the state until your filing date. Set up a dedicated liability account labeled "Hawaii GET Payable" and move the GET portion of every customer payment into it when you record the receipt. This keeps your revenue reporting clean and prevents you from accidentally spending state money before your filing is due.

Gross receipts tracking, not net deposits. GET is calculated on gross receipts — not net revenue after payment processing fees or refunds. If you use Stripe, Square, or another processor that deposits net of fees, your books need to record the gross amount charged, not the net amount deposited. The difference is small on any one transaction and significant across a full year of volume.

Monthly GET Reconciliation

Before filing each G-45, run a simple reconciliation. Pull your gross receipts for the period from your books, multiply by your applicable GET rate, and compare to what's sitting in your GET Liability account. Any difference is a recording error to find before you file, not after. This reconciliation takes fifteen minutes when your books are set up correctly. It takes hours when they're not. Build it into your monthly close routine.

If you implement the WDS banking system alongside your bookkeeping — where GET reserves are separated at the bank level when revenue lands — the reconciliation becomes a confirmation step rather than a calculation exercise.

Record Keeping Requirements

Hawaii requires you to keep GET records for seven years from the date the return was filed or due, whichever is later. Bank statements, invoices, receipts, resale certificates, and all your GET returns — all of it. Keep digital copies organized by year and by filing period. If DOTAX requests documentation, you want to pull it in minutes, not days.

For a broader resource on setting your financial foundation as a new Hawaii business, see our guide to basic finance setup for new Hawaii businesses.

Takeaway: Set up separate income accounts by GET rate category, a dedicated GET liability account, and a monthly reconciliation routine. These three steps eliminate most GET bookkeeping problems before they start.

Common GET Mistakes Hawaii Small Business Owners Make

These are the mistakes we see most often when new clients come to us after receiving a DOTAX notice. Not one of them is obscure. All of them are avoidable.

Not registering before opening. GET liability starts when you start earning revenue — not when you register. Business owners who launch first and register later owe GET on every dollar earned before registration, plus penalties and interest on all of it. Sometimes that's eighteen months of back taxes before anyone knew there was a problem.

Applying the wrong rate. The most common version: charging 4% instead of 4.5% because the owner didn't know about the county surcharge, or didn't update filings when Maui added its surcharge in January 2024. Less common but more costly: taxing wholesale transactions at the retail rate without a resale certificate on file.

Not filing zero returns. A month with no revenue is still a filing obligation. Many new business owners stop filing during slow seasons, assuming nothing to report means nothing to file. DOTAX reads missing returns as non-compliance. The penalties apply whether or not tax was owed for the period.

Confusing extension to file with extension to pay. Hawaii allows filing extensions in certain circumstances. What those extensions do not do is extend the time to pay. If you owe GET for March, a filing extension doesn't move the payment deadline. Interest and penalties on unpaid tax accrue from the original due date regardless of any extension.

Overcharging customers GET. Hawaii consumer protection rules prohibit businesses from collecting more GET from customers than the legally required amount. Charging 5% in a 4.5% county — even accidentally — can trigger consumer complaints and regulatory exposure. Use the correct 4.712% pass-on rate, and display it clearly on every invoice.

Missing resale certificates. If you sell goods at the wholesale rate, you need a G-17 on file for every buyer claiming that rate. Without the certificate, DOTAX may reclassify those sales as retail during an audit — retroactively, with penalties.

Takeaway: Every mistake on this list has a corresponding DOTAX notice attached to it in practice. Most are prevented by simple systems: the right rate, the right filing calendar, the right account structure, and documentation for every exemption claimed.

What Happens If You Don't Pay or File GET?

Penalties and Interest

Hawaii's GET penalty structure moves fast. Miss a filing, fall behind on payment, and here's what DOTAX adds:

These stack. A business with six months of unfiled returns and $20,000 in GET liability could face $5,000 in late filing penalties (25% maximum), $4,000 in late payment penalties (20%), and several hundred dollars in interest — before the original $20,000 is paid. The actual cost of non-compliance is typically 40 to 50 cents on top of every dollar originally owed.

What DOTAX Can Do

If GET goes unpaid, DOTAX has significant enforcement tools. They can file a tax lien against business — and in some cases personal — assets. They can issue a garnishment against bank accounts. In serious cases, they can move to seize and sell assets to satisfy the debt. DOTAX has become more efficient in recent years at identifying unfiled returns and cross-referencing income data. Businesses that operated off the radar five years ago are being found through routine data matching.

If You're Already Behind

Hawaii operates a Voluntary Disclosure Program. If you come forward before DOTAX contacts you, you may be eligible for penalty abatement on the amounts you self-disclose. The program doesn't eliminate the tax owed or the interest — but it significantly reduces penalty exposure. If you receive a DOTAX notice before disclosing, that window closes. Your options narrow considerably. Respond to any notice immediately and work with a Hawaii tax professional on your response and payment plan.

Takeaway: GET penalties compound fast. If you're current, stay current. If you're behind, come forward proactively — Hawaii's Voluntary Disclosure Program is the better path than waiting for DOTAX to reach you first.

Frequently Asked Questions About Hawaii's General Excise Tax

What is Hawaii's general excise tax and how is it different from sales tax?

Hawaii's GET is a tax on the privilege of doing business — applied to gross business receipts, not to the consumer at point of sale. Unlike sales tax, where buyers pay and sellers collect on behalf of the state, GET is the business owner's tax. You owe it on every dollar your business receives, regardless of whether you separately charged it to your customers. GET also applies to both goods and services, while mainland sales tax typically excludes services.

Who has to pay Hawaii GET tax?

Most Hawaii business owners — including sole proprietors, LLCs, corporations, partnerships, landlords, freelancers, independent contractors, and online sellers with Hawaii nexus. If your business earns revenue from Hawaii sources, you almost certainly owe GET. Out-of-state businesses that exceed $100,000 in Hawaii sales or 200 transactions per year must also register and pay.

What is the Hawaii GET tax rate in 2026?

The base rate for most business activities is 4%. All four counties — Oahu, Hawaii County, Maui, and Kauai — now add a 0.5% surcharge, bringing the effective combined rate to 4.5% for most businesses. Wholesale and manufacturing activities are taxed at 0.5%. Insurance commissions are taxed at 0.15%.

Is the county surcharge the same on every island?

Yes — as of January 1, 2024, all four Hawaii counties charge a 0.5% surcharge on top of the base GET rate. Oahu has had the surcharge since 2007, Hawaii County since 2019, Kauai since 2020, and Maui since January 1, 2024. If your business operates on Maui and your GET filings haven't been updated to reflect the 2024 change, review those returns — you may owe the difference.

How do I register for a Hawaii GET license?

Complete Form BB-1 (Basic Business Application) through Hawaii Tax Online at hitax.hawaii.gov. Pay the one-time $20 registration fee. You'll receive a GET license number beginning with "GE-" within approximately 5 to 7 business days. Register before your first dollar of revenue — operating without a license creates a back tax liability on every dollar earned since you started.

How often do I have to file my GET returns?

Filing frequency is based on your estimated annual GET liability. If you owe $4,000 or more per year, you file monthly. Between $2,000 and $3,999, you file quarterly. Under $2,000, you file semiannually. New businesses are assigned a frequency at registration. When in doubt, default to monthly — it's easier to reduce frequency later than to fix missed filings.

Can I pass GET on to my customers, and how do I calculate it?

Yes — Hawaii law allows you to separately state GET on your invoices and collect it from customers. The correct pass-on rate for all four Hawaii counties (which all have the 0.5% surcharge) is 4.712% — not 4% or 4.5%. If you just add 4.5%, you'll owe GET on the GET you collected, leaving you short on every transaction. Display it as a separate labeled line item on your invoice.

Can I deduct business expenses before calculating GET?

No. GET is calculated on gross receipts — the total revenue your business receives. Business expenses such as payroll, rent, materials, and overhead are not deductible from the GET base. You owe GET on every dollar that comes in, even if you lost money during that period. This is one of the most significant structural differences between GET and income tax.

What is the difference between Form G-45 and Form G-49?

G-45 is the periodic GET return filed monthly, quarterly, or semiannually throughout the year to report and pay GET for each period. G-49 is the annual reconciliation return, filed once per year, that totals all your G-45 filings against your full-year gross receipts. If you overpaid through G-45, you get a refund on G-49. If you underpaid, you settle the balance there.

What happens if I file or pay GET late?

Late filing penalties start at 5% of the tax owed per month, up to a maximum of 25%. If the tax remains unpaid after 60 days, an additional 20% penalty applies on top. Interest accrues at 2/3% per month on any unpaid balance. These penalties compound — a business six months behind with significant liability can easily face penalties totaling 40 to 50 cents on every dollar originally owed, before any of the principal is paid.

Do I have to pay GET even if I made no profit?

Yes. GET is based on gross receipts, not profit. Even if your business operated at a loss for the period, GET applies to every dollar that came in. A business that earned $200,000 in revenue but spent $220,000 running it still owes GET on the full $200,000 in receipts. This is the fundamental difference from income tax — GET does not care whether you were profitable.

Do freelancers and self-employed workers pay Hawaii GET?

Yes. Any individual earning income from self-employment in Hawaii owes GET — regardless of how they describe themselves or structure their business. Freelance designers, photographers, consultants, coaches, personal trainers, writers, and any other solo operator billing for services in Hawaii owe GET on every invoice. Sole proprietors are not exempt. If you're sending invoices, you owe GET on the total received.

Does GET apply to B2B transactions between Hawaii businesses?

Yes — GET applies even when both the buyer and seller are Hawaii businesses. This creates the "pyramiding" effect documented by the SBA as a structural disadvantage for local businesses. However, specific deductions reduce double-taxation: the subcontractor deduction in construction and the wholesale rate for goods sold for resale with a valid G-17 are the most common. Without those deductions, GET applies at every level of a multi-party transaction chain.

Do I owe GET on rental income?

Yes. Both commercial and residential rental income is subject to GET at the standard rate plus county surcharge. Short-term rentals through platforms like Airbnb or VRBO may also be subject to the Transient Accommodations Tax (TAT) in addition to GET — these are separate taxes with different rates and filing requirements. If you're a landlord or short-term rental host in Hawaii, assume both GET and TAT apply until you verify your specific situation with a Hawaii tax professional.

Calculating Hawaii's general excise tax correctly is one thing. Building it into your pricing, your banking system, and your monthly close routine so you're never short at filing time is another.
