DOTAX’s late-filing penalty is 5% of unpaid tax for each month or part of a month, up to 25%.
Hawaiʻi General Excise Tax help
Behind on General Excise Taxes?
Handle it before DOTAX handles it for you.
Missing returns and unpaid General Excise Tax can turn into assessments, liens and collection action. We help Hawaiʻi business owners figure out what is really owed, get the filings straight and deal with the Hawaiʻi Department of Taxation—commonly called DOTAX—before the problem gets harder and more expensive to fix.
Get the free Hawaiʻi GET guide by email. If you need help with an active notice or deadline, call us or request an assessment.
Got a DOTAX letter or collection deadline?
Do not set it aside. The right response depends on what DOTAX sent, what periods are missing and whether an assessment is already final.
Talk with a local Enrolled Agent nowGET trouble grows quietly
A local business problem that can become a personal burden.
General Excise Tax is not the same as a mainland sales tax. It is imposed on the business for the privilege of doing business in Hawaiʻi and generally reaches gross income—not net profit. Ordinary business expenses usually do not reduce the GET base, and even GET visibly passed on to a customer is included in gross income.
Maybe the business had one rough stretch. Maybe the G-45s were filed but the annual G-49 was missed. Maybe the books were behind, money got used for payroll or rent, and the balance snowballed. No shame. But now is the time to get a clear picture and make one workable plan.
Why delay gets expensive
The balance can grow from more than the tax.
Interest is calculated at two-thirds of 1% per month or part of a month on unpaid taxes and penalties.
Periodic returns are generally due on the 20th after each period. The annual G-49 reconciles them; it does not replace missing periodic filings.

Five unfiled years can turn $58,500 of tax into more than $105,000.

Assumptions: Service business or rental activity taxed at 4% GET plus the 0.5% Oʻahu county surcharge; monthly G-45 filing; annual income earned evenly; no returns filed and no payments made.
The late-file addition is shown at its 25% statutory maximum. The separate 25% negligence addition is a possible exposure—not an automatic charge in every case. Interest is a simplified estimate at two-thirds of 1% per month or part of a month on the assumed tax and additions.
Does this sound familiar?
Missing returns
G-45 or G-49 filings were skipped, filed wrong, or never reconciled.
Growing balance
Tax, penalties and interest keep adding up while cash flow stays tight.
DOTAX notice
A letter, assessment, lien or collection contact has raised the stakes.
Books don’t tie
Sales records, exemptions, deductions and amounts reported do not match.
Before DOTAX finds you
Voluntary disclosure may create a better path forward.
This is not a blanket “amnesty.” It is a formal, discretionary process for taxpayers who come forward before DOTAX contacts them.
The window matters
You generally must act before DOTAX contacts you.
DOTAX says taxpayers already contacted by the Department, or under federal or state audit or criminal investigation, are not eligible. Prior participation within five years can also make a taxpayer ineligible.
What the process may offer
- A path to disclose outstanding Hawaiʻi tax liabilities and file the required returns.
- Possible avoidance of a civil audit, assessment and collection process.
- Possible waiver of penalties and some interest when the taxpayer fully cooperates.
No guarantee.
DOTAX decides relief case by case. Voluntary disclosure creates no right to a waiver, may cover a look-back period of up to ten years in most cases, and must address all relevant Hawaiʻi tax types—not only GET.
Already contacted by DOTAX?
Penalty relief is possible in limited situations—but it is not the normal result.
Once voluntary disclosure is off the table, getting penalties or interest reduced is much more difficult. In a few matters, we have obtained a meaningful—but not complete—reduction based on the specific facts and circumstances.
Those resolutions required the client to pay the remaining balance in one full payment. That can be a powerful option for someone with available funds, but it is not realistic for every business. We will not build your plan around money you do not have.
Past results do not guarantee future outcomes. DOTAX makes relief decisions case by case.
The path back to pono
First, get the facts straight. Then deal with the balance.
Filing blindly or promising a payment you cannot maintain can create another problem. We work in the right order.
Find the gaps
Review the DOTAX account, notices, filing history, G-45s, G-49s and available business records.
Rebuild what happened
Reconcile gross income, exemptions, deductions and payments so decisions start with defensible numbers.
Choose the route
Evaluate voluntary disclosure, corrected or delinquent filings, full payment, a payment arrangement or other collection options.
Follow through
Complete the required filings, communicate with DOTAX and help the business stay current going forward.
