Hawaii State Tax Collector: Pay, Address, Phone & G-45

Hawaii state tax · DOTAX payment, address, phone, forms and G-45 guide

Pay, Mail or Fix a Hawaii State Tax

If you searched for the Hawaii State Tax Collector, you usually need the State of Hawaii Department of Taxation (DOTAX), Hawaii Tax Online, a tax-specific mailing address, or the current General Excise Tax form.

This guide separates state tax from county property tax, shows the correct payment and mailing routes, and explains Form G-45 rules before you open an official system or send money.

Important naming rule: Hawaii does not publish a separate public office named “Hawaii State Tax Collector.” State taxes are administered by DOTAX. “HAWAII STATE TAX COLLECTOR” is also the payee wording DOTAX uses for checks and money orders on certain filings. County real property taxes are handled separately.

Tax Lien Warning

⛔ Texas Attorney Fee Warning: After July 1, delinquent property taxes are referred to a collection attorney. An additional 15–20% attorney fee is added on top of your penalty and interest. On a $5,000 tax bill, this adds $750–$1,000 instantly. Pay before July 1 to avoid this.

Hawaii Tax Online

Pay Hawaii state taxes online without using the wrong account

Hawaii Tax Online (HTO) is DOTAX’s official self-service system for supported filings, payments, licenses and account management. Read the steps first, then open the portal.

Identify the tax type Match the return or notice: individual income, GET, withholding, TAT, corporate income, rental/tour vehicle, collection payment or another supported account.
Match the taxpayer and period Check the Hawaii Tax ID, SSN/FEIN when required, tax year/period and notice details before entering money.
Choose sign-in or Quick Links Sign in when you need messages, account management or a payment plan. For supported payments, DOTAX also allows “Make a Payment” from the HTO Quick Links without signing in.
Compare bank debit and card DOTAX says filing and ACH-debit payments through HTO are free. Credit/debit card transactions carry a vendor fee shown during checkout.
Choose the effective date carefully For EFT, DOTAX says the effective date is the date submitted, even though the tax account posts the next business day and bank withdrawal may take 2–3 banking days.
Save proof Keep the confirmation number, amount, tax type, period and bank/card record until the correct account reflects the payment.
Do not pay twice because the bank debit is still pending. A payment can have a valid DOTAX effective date before the withdrawal appears at your bank.
Mailing and payment address

Hawaii State Tax Collector mailing addresses: choose by tax type

The Honolulu street address is not a universal payment-mailing address. DOTAX publishes different PO boxes depending on the form and whether payment is enclosed.

Hawaii Form G-45: current form, filing frequency and due dates

Form G-45 is the periodic General Excise/Use Tax Return. DOTAX lists the Rev. 2025 form for taxable periods beginning on or after January 1, 2026.

First decide whether a periodic G-45 is required

Monthly / quarterly / semiannual filer File according to the filing frequency assigned to the account.
No gross income this period The current instructions say a required periodic filer still files G-45 and reports zero for the main business activity and Total Taxes Due.
Annual GET liability does not exceed $100 For periods after December 31, 2022, DOTAX says periodic G-45 filing is not required under this low-liability rule, but the annual G-49 is still required.
Seller’s collection of use tax The instructions require monthly G-45 filing for each month use tax is collected; quarterly/semiannual filing is not permitted for this registration type.

Choose the G-45 filing frequency

GET filing frequency
Expected annual GET Filing frequency Important extra rule
More than $4,000 Monthly DOTAX also requires electronic filing for taxpayers whose annual GET liability exceeds $4,000.
$4,000 or less Quarterly allowed If liability rises above the threshold, change the filing period.
$2,000 or less Semiannual allowed G-49 remains an annual requirement.

G-45 and G-49 due-date rules

Form G-45 Due on or before the 20th day of the calendar month following the end of the filing period. A January monthly period is normally due February 20.
Form G-49 annual reconciliation Due on or before the 20th day of the fourth month following the close of the tax year. A calendar-year filer is normally due April 20.
Weekend/holiday rule: if the prescribed due date falls on a Saturday, Sunday or legal holiday, the filing deadline moves to the next regular business day.
No extension for periodic G-45. DOTAX says Forms G-45 do not receive a filing extension. If exact gross income is unavailable, estimate as accurately as possible and file. G-49 may use Form GEW-TA-RV-6 for a filing-extension request, but an extension to file is not an extension to pay.

Paper G-45: avoid scanner and payment errors

Use a fresh current form; the QR/2D barcode is part of processing
Round Columns a, b and c to whole dollars; do not enter cents
If handwriting the official hand-writeable version, use black or dark-blue ink
Do not write outside the machine-readable boxes
Use the filing period format shown in the instructions
Include Hawaii Tax ID and required last 4 FEIN/SSN digits
Make a paper check/money order payable to HAWAII STATE TAX COLLECTOR
Mail GET returns/payments to P.O. Box 1425, Honolulu, HI 96806-1425

Parts and schedules that create expensive mistakes

Part V is not optional All G-45/G-49 filers must complete the Schedule of Assignment of Taxes by District. The instructions state a 10% penalty may apply for noncompliance.
More than one taxation district Attach Form G-75 and mark MULTI when income is assigned to more than one district.
Claiming an exemption or deduction Attach Schedule GE. DOTAX says unsupported exemptions/deductions may be denied.
Column b exceeds Column a Do not create a negative periodic return. The instructions limit Column b to Column a for the period and direct the remaining available exemption to a subsequent period.
2026 change in the current instructions: Act 47, Session Laws of Hawaii 2024 created a GET exemption effective January 1, 2026 for certain healthcare-provider receipts for goods/services purchased under Medicare, Medicaid and TRICARE. Eligibility and reporting depend on the specific exemption rules; do not claim it merely because a payer is healthcare-related.
Do not mass-copy a completed fillable G-45. DOTAX warns that the fillable form generates a taxpayer-specific 2D barcode. Download a fresh form for the taxpayer/period instead of reproducing another generated copy.
Official G-45 penalty rules

What happens if a G-45 is late, unpaid or filed the wrong way?

The current G-45/G-49 instructions list several different penalties. Do not use one generic “late tax” calculator because the applicable charge depends on what went wrong.

Key GET penalties and interest in the current instructions
Problem Published rule Practical next step
Late filing 5% of tax due per month or part of a month, up to 25%. File the missing return instead of waiting until full payment is available.
Timely return but tax remains unpaid 20% of tax unpaid within 60 days of the prescribed due date. Pay as much as possible and contact DOTAX if the balance cannot be resolved.
Required EFT not paid timely by EFT 2% of the tax required to be paid electronically. Use HTO/approved EFT once DOTAX says the account is mandatory-EFT.
Required electronic filing not used 2% of the amount identified in the instructions unless a waiver is obtained via Form L-110. Review mandatory electronic filing before mailing a paper return.
Part V not completed 10% of combined state and county surcharge taxes due on the return. Complete district assignment even when business is concentrated in one district.
Interest 2/3 of 1% per month or part of a month on unpaid taxes and penalties, beginning the first calendar day after payment was due. Ask DOTAX for the current payoff when resolving an old period.
Why filing still matters when you cannot pay: DOTAX’s debt guidance says to file the required return by the deadline and pay as much as possible. Once billed, payment-plan or other collection options may be available.
GET and business registration

Register for a Hawaii GET license and Hawaii Tax ID

Hawaii uses a General Excise Tax rather than a conventional mainland sales tax. Businesses commonly register through Hawaii Tax Online or Form BB-1.

GET license fee

One-time $20 registration fee.

Online BB-1

DOTAX says a Hawaii Tax ID is generally issued in about 5–7 days.

Mail/drop-off BB-1

DOTAX lists approximately 4–6 weeks.

Register New Business on HTO Use Hawaii Tax Online or complete the current BB-1 when paper registration is appropriate.
Select every tax account actually needed GET, withholding, TAT and other licenses/registrations have separate requirements and fees.
Need the ID immediately? DOTAX says an in-person BB-1 applicant may bring two completed copies and the $20 fee to a district office and receive the Hawaii Tax ID immediately.
Keep and display the license The licensing guidance says the tax license should be displayed at the place of business. Use the Hawaii Tax ID shown on it for filing and payment.
Do not confuse registration with filing A GET license does not replace periodic G-45 filings or the annual G-49 reconciliation.
Closed license? DOTAX says a closed GET license cannot simply be reactivated; a new GET license application is required to resume business.
Forms and account updates

Find the correct Hawaii state tax form and avoid wrong-year returns

Current forms

Use DOTAX Forms & Publications or the alphabetical listing. The G-45/G-49 pages identify the revision that applies to 2026 periods.

Form unavailable online

Call 808-587-4242 or toll-free 1-800-222-3229 for the Forms Request Line.

Do not change the year on a current form to file an old return. DOTAX’s FAQ says prior-year returns submitted on the wrong year’s form are rejected and returned for resubmission.
Business address changed? DOTAX points business-tax users to Form ITPS-COA for a mailing and/or business address change. Editing an address on one return is not a safe substitute for the formal account update.
Stopping GET activity? The current G-45 instructions refer to Form GEW-TA-RV-1 for cancellation and require filing through the cancellation date, including the annual return.
Electronic payment rules

When Hawaii requires EFT and what happens after payment

Mandatory EFT thresholds and payment behavior
Rule DOTAX guidance User action
Most listed tax types Mandatory EFT threshold is annual tax liability of $100,000 or more. Follow the notification letter and required EFT process.
Withholding Mandatory EFT threshold is $40,000 or more. Do not use the $100,000 threshold for withholding.
Required EFT not used timely 2% penalty may apply. Use HTO or approved ACH credit after mandatory-EFT notification.
Dishonored EFT $25 non-waivable penalty. Verify bank details and available funds.
Future-dated EFT HTO permits a postdated payment up to 120 days. Save the scheduled-payment confirmation.
Posting Posts to the tax account next business day; bank withdrawal may take 2–3 banking days. Effective date is date submitted. Do not mistake bank settlement timing for DOTAX effective date.
Collections exception: the mandatory EFT threshold rule applies to return and tax payments, not collection payments. DOTAX still recommends EFT for collection payments because it supports accurate/timely posting.
Tax debt and collections

Hawaii state tax collection notices, payment plans and next steps

If you received a delinquency letter, balance-due notice, levy warning or lien notice, treat it as a collection matter rather than a routine filing question.

If you cannot pay in full

File all required returns first
Online plan requires an unpaid balance over $100
No active plan, bankruptcy/private-collection referral or pending OIC for the online route
Approved plans carry a nonrefundable $50 processing fee
Interest and applicable penalties continue
Future returns must be filed and paid on time
More than 12 installments may require financial documents
New liabilities can default an existing plan
Missed installment warning: DOTAX says a taxpayer who cannot make a scheduled plan payment should speak with the assigned collector no later than seven business days before the settlement date.
If a payment plan will not work: DOTAX also publishes an Offer in Compromise process for certain situations involving doubt as to liability, collectability or exceptional circumstances. It is not an automatic discount program.
Refunds and notices

Refund status, tax letters and payment-posting follow-up

Individual refund status

DOTAX says Where’s My Refund becomes useful about 7–8 weeks after an electronic return or 9–10 weeks after a paper return. Status updates once daily.

DOTAX letter or bill

Use the number/instructions on the correspondence when it supplies a case-specific contact. Keep the letter ID, deadline and tax period ready.

Keep HTO confirmation number and bank proof
Match the payment to the correct tax type and period
Do not send a duplicate while the first payment is being researched
Respond promptly to identity-verification or audit notices
Escalation help

When normal DOTAX channels have not resolved the problem

Use the normal Taxpayer Services, Audit or Collection route first. If a state tax problem remains unresolved through normal channels, DOTAX publishes a Taxpayer Advocate contact.

Taxpayer Advocate

808-587-1791

For state tax problems not resolved through normal channels.

Administrative Appeals

808-587-1446

For questions about an appeal already filed or assessment appeal procedures.

Technical Section

808-587-1577

For detailed tax-law interpretation and complex technical questions.

Do not skip straight to escalation for a simple payment question. The advocate, appeals and technical offices solve different problems; sending the same question to multiple units can slow resolution.

Hawaii State Tax Collector FAQs

What does Hawaii State Tax Collector mean?

For Hawaii state taxes, the agency most users need is the State of Hawaii Department of Taxation (DOTAX). “HAWAII STATE TAX COLLECTOR” is also the payee wording used for certain checks and money orders. County real property taxes are handled by county offices instead.

What is the Hawaii state tax collector mailing address?

There is no single mailing address for every state tax. GET, withholding, TAT and rental motor vehicle tax generally use P.O. Box 1425; net income tax without payment uses P.O. Box 3559; net income tax with payment, extensions and estimated tax generally use P.O. Box 1530. Follow the current form or notice.

How do I pay Hawaii state taxes online?

Use Hawaii Tax Online. Filing and ACH-debit payments are free through HTO; credit/debit card payments have vendor fees. Supported payments can also be started through the HTO “Make a Payment” Quick Link without signing in.

What is the Hawaii Department of Taxation phone number?

General assistance is 808-587-4242 and toll-free assistance is 1-800-222-3229. For a state tax debt, Oahu Collection Branch is 808-587-1600. Use a notice-specific number when DOTAX prints one on your correspondence.

Where is the Hawaii state tax office in Honolulu?

The main DOTAX office is in the Princess Ruth Keelikolani Building at 830 Punchbowl Street, Honolulu, HI 96813-5094. General phone and walk-in hours are Monday through Friday, 8:00 a.m.–4:00 p.m., closed on state holidays.

Where can I get current Hawaii state tax forms?

Use the official DOTAX Forms & Publications page or alphabetical form listing. If a form is not available online, call the Forms Request Line at 808-587-4242 or 1-800-222-3229. Do not change the year on a current form to file a prior-year return.

What is Hawaii Form G-45 and where do I mail it?

G-45 is the periodic General Excise/Use Tax Return. Rev. 2025 applies to taxable periods beginning on or after January 1, 2026. Paper GET returns/payments are mailed to Hawaii Department of Taxation, P.O. Box 1425, Honolulu, HI 96806-1425. Follow the current form for check-identification details.

When is Hawaii Form G-45 due?

G-45 is due by the 20th day of the calendar month following the filing period. G-49 is due by the 20th day of the fourth month after the tax year closes. G-45 does not receive a filing extension; a G-49 filing-extension request does not extend the time to pay.

Do I still file G-45 when I had no income?

If you are otherwise required to file a periodic G-45, the current instructions say to file even when there is no gross income for the period and report zero on the applicable activity and Total Taxes Due. A separate low-liability rule says taxpayers whose annual GET liability does not exceed $100 are not required to file periodic G-45 returns for periods after 2022, but G-49 remains required.

Does Hawaii DOTAX offer payment plans for state tax debt?

Yes. Eligible taxpayers may request a Payment Plan Agreement. Approved plans have a nonrefundable $50 processing fee, while interest and applicable penalties continue. Online eligibility includes an unpaid balance over $100 and other restrictions; longer plans may require financial documents.
