How to Get an EIN in Hawaii (and Your Hawaii Tax ID)

Getting your Hawaii EIN is the free, fast part: as of 2026 the IRS issues it online in about 15 minutes, same day, at no cost. The Hawaii-specific work comes next. After you form a Hawaii LLC, you use the EIN to register with the Department of Taxation through Hawaii Tax Online on Form BB-1. A $20 General Excise Tax license applies if you sell anything.

Do You Need an EIN for Your Hawaii LLC?

Most Hawaii LLCs need an EIN, and the rule turns on how the limited liability company is taxed and whether it hires. A single-member LLC with no workers is a disregarded entity federally, so the IRS doesn’t strictly require one.

Here’s the Hawaii catch: Form BB-1 expects a federal EIN from every business except a no-employee sole proprietor and most nonprofits. A single-member LLC selling anything in the state should get one regardless.

Multi-member owners should pair it with a Hawaii LLC operating agreement that keeps the tax classification and member splits clear. Check the Hawaii LLC filing fees too, so the $50 formation cost and $20 GET license aren’t a surprise.

How to Get Your Hawaii EIN Through the IRS, Step by Step

Most Hawaii owners finish online in about 15 minutes, once the LLC is approved. Run the steps in this order and refiles drop to zero.

1. Confirm the LLC is approved: the EIN name must match the registered entity, so wait until the Department of Commerce and Consumer Affairs clears your Articles of Organization. Check how long a Hawaii LLC takes to approve first.
2. Open the IRS EIN Assistant: the free tool runs Monday to Friday 6 a.m. to 1 a.m. Eastern the next day, Saturday 6 a.m. to 9 p.m., and Sunday 6 p.m. to midnight. It can’t be saved and expires after 15 minutes idle.
3. Pick the right entity type: this screen sends people back to the start, so match your federal tax treatment, not whatever sounds closest.
4. Enter the legal name, then any trade name: the legal name is the one on file; a DBA goes in the trade-name field.
5. Name the responsible party: a natural person with an SSN or ITIN who controls the LLC, not another company. A foreign owner with no SSN enters “foreign” on that line.
6. Download the CP 575 immediately: this EIN confirmation letter appears once, and the IRS won’t mail a copy if you took it online.

After Hawaii EIN Approval: Save Your CP 575 Before You Register for GET

Once the IRS approves your EIN, the number is only half the job. The CP 575 is the official EIN confirmation letter, and Hawaii owners usually need it almost immediately for the next state step: registering through Hawaii Tax Online with Form BB-1.

Save the CP 575 as a PDF before you close the IRS screen, then keep a backup with your Hawaii LLC formation records. This is especially important in Hawaii because the EIN is often used right away when applying for the General Excise Tax license, withholding account, or other Department of Taxation accounts.

Do not confuse the CP 575 with your Hawaii Tax ID. The EIN on the CP 575 comes from the IRS, while Hawaii Tax ID accounts such as GE for General Excise Tax and WH for withholding come from the Hawaii Department of Taxation. If you later hire employees, unemployment registration is handled separately through the Department of Labor and Industrial Relations.

If you lose the CP 575, the IRS will not simply reissue the same confirmation letter. You may need to request a 147C letter instead, which can slow down bank account setup, Hawaii Tax Online registration, or payroll onboarding.

The EIN is free from the IRS, so skip the third-party sites that charge $150 to $300 for it. Apply at IRS.gov yourself, or have a Hawaii LLC formation service file it inside a package you trust.

Not in the U.S.? International applicants without an SSN can’t use the online tool; they call 267-941-1099 on weekdays, or fax or mail Form SS-4 (fax about four business days, mail roughly four weeks). One limit applies to everyone: one EIN per responsible party per day.

What to Have Ready Before You Apply

A few details up front keep the application clean. The big one is sequence: form the Hawaii LLC before you apply, so the CP 575 carries the exact approved name and you don’t redo it.

Have these ready before you open the EIN Assistant:

• The approved legal name, matched to the state’s record (a quick Hawaii business entity search confirms the spelling)
• The DCCA Business Registration Division file number and formation date
• The responsible party’s name and SSN or ITIN
• Your federal tax classification
• A reason for applying and a Hawaii business address

A mismatch between the EIN name and the DCCA record quietly causes bank-account rejections later, and it’s hard to catch until the account won’t open.

EIN vs Your Hawaii Tax ID Number (GE, WH, and DLIR Accounts)

This is where owners confuse the EIN with the state’s numbers, and Hawaii hands out more than one. The EIN is your single federal ID; the Hawaii side splits into tax accounts at the Department of Taxation and a payroll account at the labor department.

The Hawaii Tax ID carries a prefix for the account: GE for general excise and use, WH for withholding, TA for transient accommodations, RV for the rental-vehicle surcharge. One business can hold several under the same Hawaii Tax ID.

Counting the formation filing, that’s four separate records: the DCCA entity, the IRS EIN, the DOTAX Hawaii Tax ID, and a DLIR unemployment account for employers. They’re four numbers from four agencies.

Registering for GET, Withholding, and DLIR Unemployment After Your EIN

With the EIN in hand, the Hawaii registrations open up. Most LLCs hit the General Excise Tax first, then withholding and unemployment once they hire, and the EIN feeds every one of them.

Hawaii GET License: the Sales-Tax Equivalent

Hawaii doesn’t have a traditional sales tax. It runs the General Excise Tax, a tax on the business’s gross income rather than a charge added to the buyer’s receipt. Sellers may pass it on, but only within published limits.

You register through Hawaii Tax Online on Form BB-1, the State of Hawaii Basic Business Application, for a one-time $20 license fee. Online filings return a Hawaii Tax ID in about five business days to a week. Mail takes four to six weeks; an in-person visit to a district office in Honolulu, Hilo, Maui, or Kauai is same-day.

GET runs at 4% on most retail, 0.5% on wholesaling, and 0.15% on insurance commissions. On the 4% activities a county surcharge of 0.5% applies in Honolulu, Maui, Kauai, and Hawaii County through 2030, so a Honolulu seller can pass on up to 4.712%.

When Your Hawaii LLC Hires: Withholding and Unemployment

Hiring opens two separate payroll accounts: income-tax withholding at the Department of Taxation, and unemployment insurance at the labor department.

Withholding has no fee and goes on the same BB-1. Employers file Form HW-14 quarterly, due April 15, July 15, October 15, and January 15. From January 1, 2026, businesses with 10 or more W-2 or HW-2 forms a year must file electronically.

Unemployment runs through the Department of Labor and Industrial Relations, not DOTAX. New employers file Form UC-1 to determine liability, then report wages quarterly on Form UC-B6; the 2026 taxable wage base is $64,500 and the new-employer rate is 2.40%.

Do Out-of-State Sellers Need a Hawaii GET License?

Worth flagging: a business with no physical presence can still owe GET. Hawaii’s economic-nexus rule pulls in any seller with $100,000 or more in Hawaii gross income, or 200 or more separate transactions, in the current or prior calendar year.

That sweeps in ecommerce shippers, SaaS firms with island customers, and service providers whose work is used in Hawaii. Out-of-state owners lean on a Hawaii registered agent to catch the state notices they’re too far away to receive.

Activity-Specific Hawaii Tax Accounts

Beyond GET, some lines add their own BB-1 license. Short-term rentals carry transient accommodations tax, and rental vehicles, liquor, tobacco, and liquid fuel each register separately.

EIN Mistakes That Cost Hawaii LLC Owners GET and Payroll Time

A handful of mistakes recur on Hawaii applications, and most cost time, not money. The pattern is treating the EIN as if it covers the state, when it doesn’t.

The federal slips are universal: the wrong entity classification on Form SS-4, an entity named as responsible party instead of a person, or a second application that creates a duplicate EIN.

The Hawaii ones bite harder. Owners think the EIN registers them for GET, when it doesn’t. Others hunt for a seller’s permit Hawaii never issues, or assume one GET license covers withholding and unemployment, which sit at two agencies.

Single-member owners trip on the disregarded-entity rule, assuming federal pass-through removes the state license. It doesn’t, and the EIN sits under ongoing duties like the Hawaii LLC annual report the state expects each year.

Finding a Lost Hawaii EIN or Updating Your LLC

Misplacing the EIN happens, and it’s recoverable. Check the CP 575 first, then prior federal returns, bank records, or any payroll filing, since the number prints on all of them.

If none turn up, ask the IRS for a 147C letter, the official replacement confirming an EIN was previously assigned. An EIN lookup tool can also surface it from public records. The Hawaii Tax ID is separate and lives in your Hawaii Tax Online account.

Some changes need a new EIN, some don’t. A structural change like converting a sole proprietorship to an LLC, or going from single-member to multi-member, triggers a fresh number. A plain name or address change doesn’t, and goes on Form 8822-B or 8832.
