How to convert a sole proprietorship to an LLC in Hawaii

Hawaii has no conversion filing for a sole proprietor

You cannot convert what the state never registered. A Hawaii sole proprietorship has no entity record with the Business Registration Division, so there is nothing on file to change into an LLC.

Hawaii does have an Articles of Conversion form, and the name suggests it does this job. It does not. The form's converting-entity options are corporations, partnerships, and limited liability companies, at a $100 filing fee. A sole proprietorship is not on the list.

So the move is a formation. You file Articles of Organization, create a new company, and carry the business across yourself. The proprietorship does not become the LLC. The LLC takes over the proprietorship's work.

That framing matters for every step below. Nothing transfers automatically, because there is no entity on the state's books to transfer from.

Form X-10Hawaii's Articles of Conversion form (X-10, $100 filing fee) lists the converting-entity options as corporation, partnership, and LLC types, and a sole proprietorship is not among them. — Hawaii Department of Commerce and Consumer Affairs, Business Registration Division, retrieved 2026-09-29

Deciding what the LLC will hold before you file

Work out three things on paper first: the name, the registered agent, and what the company will actually own.

The name needs the letters LLC in it and must not match an existing Hawaii entity. You can check it in the state's business name search before paying anything, and the filing fee is not refundable if the name is rejected.

The registered agent is required by statute. Each LLC must have and continuously maintain a Hawaii registered agent who has a business address in the state, either an individual residing in Hawaii or an entity authorized to transact business there. You can be your own agent. Many owners are not comfortable with that, because the agent's address is where legal papers get served, and it sits on the public record.

The ownership question decides the rest of the schedule. A single-member LLC keeps one federal tax return unchanged. Adding members changes the federal side to a partnership return, and it forces a new EIN. If you are on the fence about a partner, settle it before the filing.

Filing the Articles of Organization

The filing itself is Form LLC-1, Articles of Organization, with the Business Registration Division. The fee is $50, online or on paper, and expedited handling adds $25 if the division offers it at the time.

You can prepare and file it yourself through the state's portal, or have a formation service do the typing and the filing for you. Either way the Articles go to the same place and cost the same $50.

The Articles ask for the company's name, its Hawaii address, the registered agent's name and street address, and how the company is managed. Nothing about your old proprietorship goes in the filing. The state is not told you ever existed as a business, which is the same reason nothing carries over.

Most single-owner filings go through in the state's normal queue. The division was transitioning to a new portal when this was written, and it warned that expedited handling was not always available, so build slack into any date you promised a customer paperwork for.

Writing the operating agreement and opening accounts

Hawaii does not require an operating agreement, but write one anyway. It is the document that says the business income, contracts, and assets belong to the LLC rather than to you personally.

The agreement is also where you record what the company took over from the proprietorship and what it did not. A short schedule of transferred assets, dated, is the cleanest evidence you will ever have if anyone asks where the line between you and the company sits.

Then open a business bank account in the LLC's name. Every dollar of business income lands in it, and no personal spending comes out of it. The liability wall the LLC gives you is only as strong as this separation. Commingled accounts are the first thing a plaintiff looks for.

Your vendors will ask for a W-9 from the company. That is the point where the EIN question comes up, and it has its own page: EIN and tax IDs after converting.

The IRS states that a W-9 from a single-member LLC disregarded for federal income tax should provide the owner's SSN or EIN, not the LLC's EIN. — Internal Revenue Service, retrieved 2026-09-29

Re-issuing the tax registrations

Hawaii's Department of Taxation treats the LLC as a separate taxpayer from you, even when the IRS does not. The LLC must obtain its own general excise tax license and file its own state tax returns, whatever the federal treatment.

The license comes from Form BB-1, the Basic Business Application, with a one-time $20 fee. If your proprietorship had a trade name on file and you want to keep it under the company, the trade name needs the LLC's name on it too.

The GET license and the returns behind it have enough moving parts to fill their own page, including what stays the same on your federal return: taxes after the conversion.

Re-issuing what the boards issued to the business

Licenses issued to you personally stay with you. Licenses issued to the business have to be done again in the LLC's name.

The sharp example is the contractor license. When a sole proprietor forms a contracting entity, the Contractor License Board requires the entity to apply for a new license, and the individual's license converts to a responsible managing employee designation. Two licenses, then, where there was one.

Food permits, shop licenses, and the county pieces move the same way. The full walk-through, trade by trade, is on the licenses and permits guide, and your trade may have its own page if it is one of the five covered here.

Do not let the old license lapse in the gap. The board's calendar and your LLC filing date are two different clocks, and a gap between them can leave you unable to take work legally.

Moving the contracts and the cover

The commercial paper does not move by itself. A contract signed by you as a sole proprietor still binds you, not the LLC, until the other side agrees to a new one.

The practical route is a short assignment or novation per counterparty, timed with the insurance update so no certificate of insurance shows the wrong insured when a customer checks. Bonds and workers' compensation move with riders, not goodwill.

The pattern, with what to say to an agent and a customer, is on the contracts and insurance guide.

The Contractor License Board's conversion filing attaches riders or new certificates of liability and workers' compensation insurance, and a bond rider where a bond is required. — Hawaii DCCA, Contractor License Board, retrieved 2026-09-29

Closing out the proprietorship cleanly

Once money moves under the LLC, the proprietorship's registrations should be closed rather than left open.

Tax registrations are cancelled on Form GEW-TA-RV-1. A final GET return reconciles the proprietorship's receipts up to the changeover date. Leaving the old license active reads to the Department of Taxation as an abandoned registration, and abandoned licenses are revoked for cause.

Keep the proprietorship's books. The final returns, the closed license record, and the asset schedule in the operating agreement are the set of documents that shows the move was real and dated.

The dates that start ticking on the filing date

The annual report is the one yearly state filing. It costs $15 and falls due on the last day of the quarter matching your filing date: file in September, and every future report is due September 30.

One break in the first year: an LLC organized in the same year the report would come due does not owe one that year. After that the report is annual, and it reflects the company's affairs as of the start of its quarter.

Trade renewals sit on their own boards' calendars, which are not the LLC's. The electrician's three-year clock and the contractor's even-year September clock keep running regardless of what the company's formation date is. The checklist pulls all of these into one list.
