Restaurant Name Change: Do You Need a New EIN?

Not for the name alone. A legal name change still has to be reported to the IRS; for a trade-name-only change, ask first. The answer can change when ownership or structure changes too. Here's how to tell which case you're in before you apply for a number or keep the old one.

Quick answer: No. The IRS says you don't need a new EIN if you only change your business name or address. If the company's legal name changes, you still have to tell the IRS, and how you do that depends on how the business files its federal taxes. If only the name on the sign changes (a trade name, or DBA), the IRS page doesn't say whether it needs a notice, so ask your accountant or the IRS first. The answer can change if the new name comes with a change in who owns the business or how it's set up, like a sole owner incorporating or taking on a partner, or a buyer taking over someone else's restaurant. Then you check the IRS rules for your entity type with your accountant before you apply for a new number or keep using the old one.

This answer covers the federal EIN for a US restaurant business. It doesn't cover state entity filings, trade name (DBA) registrations, permits, sales tax or payroll accounts, which follow their own rules where you operate. It isn't tax or legal advice for your entity. The IRS and SBA pages cited here were read on October 18, 2026.

What the IRS says about a name change

The IRS page When to get a new EIN, last reviewed July 21, 2026, starts with two lines: “You need a new EIN, in general, when you change your entity’s ownership or structure.” and “You don’t need a new EIN if you just change your business name or address.” The lists for sole proprietors, corporations, partnerships and LLCs on that page each put a name change on the no-new-EIN side.

No new number doesn't mean nothing to do when the legal name changes. The IRS Business name change page, last reviewed February 22, 2026, says the action required “may vary depending on the type of business”:

Sole proprietorship: write to the IRS at the address where you filed your return. The owner or an authorized representative signs it.
Corporation: if you're filing the current year's return, mark the name change box on it. If that return is already filed, write to the IRS at the address where you filed it. A corporate officer signs.
Partnership: the same pattern with the current-year partnership return. A partner signs.

Your accountant can point to the exact box on the return you actually file. A few other details from that page matter before opening:

If your EIN was recently assigned and your “filing liability has yet to be determined,” which can describe a restaurant that got its number shortly before opening, the page says to send the name change request to “the IRS address where you file your return.” Ask your accountant which address that is for you.
If you want proof the IRS has the new name, the page says to ask for an acknowledgement.
The page also warns: “In some situations a name change may require a new Employer Identification Number (EIN) or a final return.” It doesn't list those situations; it points to Publication 1635. The cases where the IRS does require a new EIN are about ownership and structure, so a name change that arrives with one of those is the one to check. The next section covers it.

Check what goes with the notice, too. Publication 1635 (February 2014 revision), which the name change page points to, says “partnerships and corporations must include a copy of the Articles of Amendment that were filed with the state that authorized the name change.” The 2026 web pages don't repeat that line, but they don't withdraw it either. Before you mail anything, ask your accountant or the IRS what applies to your business and what to attach.

Be clear about which name is changing. Your company's legal name and the name on the sign can be different. The SBA's business name guidance says the entity name, trademark, DBA and domain name are legally independent registrations, and that you might need to register a DBA with your state, county or city. The IRS name change page doesn't say whether changing only a trade name needs a notice. If that's your case, get an answer from your accountant or the IRS before you send one, even if nothing else about the business is changing.

When the name isn't the only thing changing

The EIN goes with the taxpayer, not the sign over the door. So the question to answer is: after the change, is the same sole proprietor, partnership, corporation or LLC running the restaurant, set up the same way? If yes and only the name moved, the rule above applies. If not, look at the IRS list for your entity type. These are the parts of the July 2026 page most likely to come up for a restaurant:

Sole proprietor: new EIN if you incorporate or form a partnership. Not for a new name or location, or for owning more than one business.
Partnership: new EIN if you incorporate, one partner takes over and runs it as a sole proprietor, or the partnership ends and a new one begins. Not for a new name, or for “a change in ownership that does not result in the termination of the partnership.”
Corporation: new EIN if you get a new charter from the secretary of state, become a subsidiary, change to a partnership or sole proprietorship, or merge and create a new corporation. Not for a new name, for choosing to be taxed as an S corporation, or for converting at the state level without changing your business structure.
LLC: new EIN if you terminate the LLC and form a new corporation or partnership, or if you own a single-member LLC that has to file employment or excise taxes. Not for a new name, or for changing your tax election to a corporation or S corporation.

None of those lists says every ownership change means a new EIN. The partnership list says the opposite for an ownership change that doesn't end the partnership. That's why a takeover needs facts, not a rule of thumb. Don't assume the seller's number comes with the restaurant, and don't assume you need a new one either. It depends on what you're actually buying and which company will run the restaurant after closing. Our guide to buying an existing restaurant explains why buying equipment, buying business assets and buying a company are different transactions. Get the EIN answer from your attorney or accountant with the deal documents in hand, before anyone applies for a number or puts one on payroll or permit paperwork.

A change in who controls the business is a separate IRS update from the name. The IRS page on responsible parties, last reviewed August 22, 2026, says to use Form 8822-B to report a change to your responsible party, address or location. The form itself (December 2019 revision) says an entity with an EIN reports a responsible party change within 60 days. Form 8822-B isn't the name change route.

If you have an LLC, find out how it's taxed first

The name change page gives routes for a sole proprietorship, a corporation and a partnership. It has no LLC row, and the IRS doesn't tax every LLC the same way. Its LLC page, last reviewed October 10, 2026, says that depending on its elections and number of members, an LLC is treated as a corporation, a partnership or part of its owner's return (a “disregarded entity”). By default a domestic LLC with two or more members is a partnership, and a single-member LLC is disregarded for income tax, unless it elects to be treated as a corporation.

So the letters LLC on your state papers don't tell you which route to use. If you don't know how your LLC files, find out from your accountant or the IRS before you mark a box or write a letter. Don't guess.

One LLC point matters before your first payroll. The same IRS LLC page says a single-member LLC is still a separate entity for employment and certain excise taxes, and the new-EIN page lists a single-member LLC that has to file employment or excise taxes as a case for a new EIN. If your LLC has been using your sole proprietor EIN and you're about to hire, check this with your accountant now.

Two fictional examples

Same LLC, new name before opening

Two co-owners formed a made-up LLC called Harbor Street Kitchen LLC to open a restaurant under that name. Before opening, they decide to call it Saltline instead. It's the same LLC with the same two members, and nothing else changes.

They don't need a new EIN for the name. Their accountant confirms the LLC files as a partnership, so the partnership row of the IRS name change page is their route. They still decide whether they're amending the LLC's legal name with the state or only registering Saltline as a trade name, and they ask the accountant whether that choice changes what goes to the IRS and what to attach. Then they update the bank, permits, insurance and payroll provider, each through its own process.

New name and a new owner

A buyer is taking over Pine Hollow Grill, a made-up restaurant owned by the seller's corporation, and will reopen it as Ember Room. Two things are changing: the name and who owns the business. The name-only rule doesn't settle this one.

The buyer doesn't apply for an EIN yet and doesn't start using the seller's number. The answer turns on whether the buyer is acquiring the corporation itself or buying assets into another company, and on which company will run Ember Room. The buyer fills in the note below, marks the taxpayer question UNKNOWN, and sends it to their attorney and accountant with the draft deal documents.

Copy this note before you file anything

Fill in one note per business before you write to the IRS, apply for an EIN or keep using an existing one after a change. It's written to make sense on its own if you hand it to a partner or your accountant.
