How to Get an EIN for Your eBay Business (Free, Step by Step)

Sooner or later an eBay seller hits a form that asks for a tax ID, and the first search result is a slick website offering to "file your EIN" for a fee. The number itself is free. It comes straight from the IRS, usually in a few minutes, and the only real work is choosing the right answers on the application so you do not have to fix them later.

This guide covers what an Employer Identification Number (EIN) is, whether an eBay seller actually needs one, how the IRS online application works, which answers to give if you are a sole proprietor or an LLC, how eBay uses the number, and what to do afterwards. Everything below was checked against IRS and eBay pages in October 2026, and the links are in the sources list at the end.

1. What an EIN is and what it is for

An EIN is a federal tax identification number. The IRS describes it as the number it assigns to sole proprietors, corporations, partnerships, estates, trusts and other entities for tax filing and reporting. In its instructions for Form SS-4 (the paper version of the application), the IRS says the EIN is for use in connection with your business activities only, and is not a substitute for your Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN).

In practice it does the same job for a business that your SSN does for you personally. You give it to banks when opening a business account, to payment platforms, to suppliers who ask for a tax ID on a form, and to the IRS on business returns. It is different from a state tax ID or a seller's permit, which come from your state and are covered in our guide to resale certificates and seller's permits. The SBA says you need a state tax ID only if your business must pay state taxes, which depends on your state.

2. Do you actually need an EIN to sell on eBay?

There are two separate questions here: what the IRS requires, and what is convenient or required by the platforms you use.

What the IRS says about who needs one

The IRS lists these situations on its page about employer ID numbers: you have employees; you pay employment, excise, or alcohol, tobacco and firearms taxes; you withhold taxes on non-wage income paid to a nonresident alien; or you operate a partnership, LLC, corporation, tax-exempt organization, estate, certain trusts, a retirement plan or IRA, or a farmers' cooperative. The same page adds that you can also get an EIN even if you do not need one for federal tax purposes, and that you can still request one for banking or state tax purposes.

The SBA's list is similar: paying employees, operating as a corporation or partnership, filing certain excise or employment tax returns, and so on. Its page on tax IDs even words the banking line as an EIN "or a Social Security number, if you're a sole proprietorship". So a one-person seller with no employees, trading under their own name, is not forced by those lists to get an EIN.

What eBay asks for

eBay's "Registering as a seller" help page separates individual sellers from registered business sellers. Individual sellers give a full name, address, date of birth and SSN. The page says registered business sellers include sole proprietors, single-member LLCs, corporations and multi-member LLCs, partnerships, publicly traded companies and charities, and that these sellers provide the legal business name, any DBA name, an EIN and a physical business address. The same page says that if you have not given eBay an SSN, EIN or ITIN, it will ask for one, and that it encrypts and securely stores it.

That makes the practical answer clear for anyone who plans to run eBay as a real business, including dropshippers:

• If you register as a business (including a sole proprietorship), expect eBay to ask for an EIN.
• If you form an LLC or corporation, you will need one, because those entities are on the IRS list above and because eBay's business registration asks for it.
• If you hire anyone, you need one for employment taxes.
• If you stay an individual seller with no employees, the IRS does not make an EIN compulsory. You can still apply: the IRS says you may get one even when you do not need it for federal tax purposes.

Whichever route you choose, remember that the tax number does not decide whether your eBay profit is taxable. Our guide to eBay seller taxes, sales tax and 1099-K explains the income side. An EIN simply identifies you.

Worth remembering: getting an EIN does not create a company. A sole proprietor with an EIN is still a sole proprietor.

3. Before you apply: sort out your structure and your details

The IRS tool is quick, but a few decisions have to be made before you open it, because some of them are awkward to undo.

Form the entity first if you are making an LLC or corporation

The IRS says that if you are forming a corporation or LLC, you should form it with your state first. Applying earlier may delay the EIN. The business name you enter should be the name on your formation documents.

Know your responsible party

Every application names a responsible party. The IRS defines this as the person who owns, controls or exercises effective control over the business and who manages its funds and assets, directly or indirectly. Unless the applicant is a government entity, it must be an individual, not a company. For a sole proprietor, that is you. For a single-owner LLC it is the owner. For a partnership with several partners, the IRS says to list the person you want it to recognize.

Nominees cannot apply. The IRS describes a nominee as someone with limited authority to act for your entity during formation, such as a person who helped with state paperwork, and says they should not be listed on Form SS-4. If you used a nominee for state formation, identify the real responsible party before applying. If a nominee has already been listed, the IRS says to correct the application.

Have the right ID number ready

The online tool is for applicants whose principal place of business is in the United States or its territories. You must be the responsible party, or an authorized representative of the responsible party, and you need the responsible party's SSN or ITIN. If you cannot meet those conditions, for example because your principal place of business is outside the US, the IRS directs you to phone, fax or mail instead (the phone line for international applicants is 267-941-1099, Monday to Friday, 6 a.m. to 11 p.m. Eastern).

Check your name and address formatting

The IRS says business names may only contain letters, numbers, hyphens and ampersands. Street addresses are limited to 35 characters. eBay's own 1099-K page advises that the name on your eBay account match the name on your tax ID and on your federal and state income tax returns.

4. The online application, step by step

Here is how to work through the IRS online application. The IRS can change the screens, so treat the order below as a guide to what you will be asked rather than a script.

1. Check the hours. The tool runs on Eastern Time: Monday to Friday 6 a.m. to 1 a.m. the next day, Saturday 6 a.m. to 9 p.m., and Sunday 6 p.m. to midnight.
2. Use only the official IRS page. The address is on irs.gov. The IRS warns on its own pages to beware of websites that charge for an EIN, and states that you never have to pay a fee.
3. Be ready to finish in one go. The application cannot be saved. It times out after 15 minutes of inactivity, and you must then start again.
4. Choose your entity type. The tool asks what kind of entity you are. Pick the one that truly matches your situation; the next section explains the common eBay cases.
5. Enter the responsible party's details. You will need the SSN or ITIN for that person.
6. Enter your business name and address following the formatting rules above.
7. Review and submit. If approved, the EIN is issued immediately online.
8. Print or save the confirmation. The IRS tells applicants to print the confirmation letter for their records.

5. Which answers to give: sole proprietor, single-member LLC, or something else

The question most new eBay sellers get stuck on is the entity type. The IRS Form SS-4 instructions give the clearest guidance, and the online tool follows the same categories.

Two points deserve a closer look.

A sole proprietor with several eBay stores or trade names

The Form SS-4 instructions state that a sole proprietor generally needs only one EIN, even with multiple businesses or trade names. Its page on when you need a new number agrees: for a sole proprietor, changing your business name or locations, or owning multiple businesses, does not require a new EIN. So a name change from a first store to a second brand does not mean another application.

Single-member LLCs and the "disregarded" label

"Disregarded" is a tax term, not a statement that the LLC does not exist. The IRS Limited Liability Company page says a single-member LLC is treated as an entity disregarded as separate from its owner for income tax, unless it elects corporate treatment through Form 8832, but is still treated as a separate entity for employment taxes and certain excise taxes. Which tax ID goes on a given form can therefore depend on the form. The Form W-9 instructions say the owner of a disregarded entity is the one who provides the W-9 for the purposes they describe, with the owner's name on line 1 and the entity's name on line 2. Ask an accountant which number belongs on which form.

6. Other ways to apply, and how long they take

If you cannot or prefer not to use the online tool, the IRS accepts Form SS-4 by fax or mail from US applicants. The IRS says that if you fax Form SS-4 to 855-641-6935 and include your fax number, it faxes back a cover sheet with your EIN in about four business days. By mail the form goes to Internal Revenue Service, Attn: EIN Operation, Cincinnati, OH 45999, and the IRS says to expect about four weeks. Use one method per entity.

A third party can apply for you only with your signed authorization. If an accountant or formation service helps with your LLC, check what exactly you are paying for, because the IRS number itself is free.

7. After you get the number

When you can use it

The IRS says you can use an EIN immediately to open a bank account, apply for business licenses or file a paper return by mail. It says some electronic uses can take up to two weeks, for example passing the TIN Matching Program check, e-filing, or making electronic tax deposits. If a return is due before your EIN arrives, the IRS says to write "Applied For" and the application date in the box.

Open a matching bank account

eBay's page says the names on your bank account and your eBay account must match, and that account types must match: a business eBay account needs a business checking account. If your eBay account is registered under a business name, that name is what should be on the checking account. Our guide to eBay Managed Payments payouts covers how payouts work.

Update eBay

Enter the EIN in your seller registration or tax settings, using the legal name exactly as it appears on your IRS notice. If eBay asks you to verify a business account, the eBay registration page accepts an IRS 147C EIN verification letter, or any IRS document showing your full name, full address and tax number, and says documents completed by the customer, such as a W-9, are not acceptable. For a sole proprietor it also lists other options, such as redacted tax returns or a government-issued business license. If you do not have a 147C, the next section explains how to request one.

Keep an eye on 1099-K matching

eBay's 1099-K page says eligible sellers receive the form in their account by January 31 each year for the prior calendar year, and that it shows the gross payments, the number of transactions, your name, address and tax ID. It also says multiple accounts under the same tax ID are combined when measuring the threshold. The page's figures for 2025 were more than $20,000 in gross payments and more than 200 transactions, and the IRS has said that the reporting threshold for third-party settlement organizations reverted to $20,000 with more than 200 transactions. eBay's page adds that sellers can also receive a form if they meet IRS or state minimums. Thresholds change, so check the current eBay and IRS pages each January. Enter your legal name and number exactly as they appear on your IRS notice.

8. Lost your EIN, or need a letter that proves it

If you cannot find your EIN, the IRS suggests looking at the notice you received when you applied, at your business bank, at state or local license records, and at past business tax returns. If those fail, it says to call 800-829-4933, Monday to Friday, 7 a.m. to 7 p.m. local time, after which the IRS verifies your identity before providing the number.

To confirm an EIN, the IRS lists three routes: request an entity transcript, download a CP 575 notice if you are an eligible Business Tax Account user, or call the business tax line and request Letter 147C.

9. When you need a new EIN, and when you do not

The IRS says you generally need a new EIN when the ownership or structure of the entity changes. The IRS page gives examples for sole proprietors:

• New EIN: you incorporate, you form a partnership, or you declare bankruptcy.
• No new EIN: you change your business name or locations, or you own more than one business.

For partnerships and corporations the IRS page lists its own examples, and it says that choosing S corporation taxation does not require a new number. Check the IRS page for your exact change, because the rules differ by entity type.

Some changes need reporting even though the number stays. The IRS says to report changes to your responsible party, address or location on Form 8822-B within 60 days. The IRS also says that a business should have only one EIN, and that it cannot cancel an EIN, though it can deactivate one you no longer need.

10. Common mistakes

1. Paying a third-party site. The IRS says the number is free. Use the irs.gov application.
2. Applying before forming the LLC. The IRS warns this can delay the number.
3. Listing a nominee or helper as the responsible party. Name the person who really owns or controls the business.
4. Choosing the wrong entity type. With one EIN per responsible party per day, check the entity table above before you submit.
5. Name mismatches. eBay says bank and eBay account names must match.
6. Letting the session time out. Fifteen minutes of inactivity and you start over, so gather your details first.

11. What to do next

When you are ready to price products properly, the US eBay fee calculator works out what a sale really leaves you with, and Sellhelm, the eBay dropshipping software this blog belongs to, prices each listing from your real fees. The next steps in setting up are covered in our US guide to starting on eBay and the dropshipping guide.
