Sole Proprietorship or LLC? Choosing Your Business Type at Signup

"Amazon business sole proprietorship or other" is a real, frequently-searched query, and it comes from a real moment of hesitation at the registration screen: a dropdown asking for something that sounds legally consequential, on a form you were expecting to breeze through.

The reassuring answer is that Amazon has published exactly who it will accept, and the list is close to exhaustive.

Who Amazon says can register

The Amazon Business Accounts Terms and Conditions define Eligible Entities in a single sentence that covers nearly every reader of this page:

• All types of businesses — LLCs, LLPs, corporations, partnerships, sole proprietorships and PLLCs
• All types of governmental entities — federal, state, local and quasi-governmental
• All types of non-profit organizations — including 501(c) organizations, 527 organizations and similar tax-exempt organizations

The same section adds the line that resolves most of the anxiety around this question: individual consumers should use Amazon.com. The dividing line Amazon draws is business-versus-consumer, not incorporated-versus-unincorporated.

The terms also ask you to represent that the individual registering has the authority to bind the customer. For a sole proprietor that is trivially you. For an LLC or a corporation it is worth a moment's thought if the person doing the signup is an office manager rather than an owner.

Which option to select

Match reality. It really is that simple, and the reason is that the field is descriptive: Amazon uses it to characterize the account, not to grade it.

• You never filed formation paperwork and you trade under your own name or a DBA — you are a sole proprietorship.
• You filed articles of organization — you are an LLC, single-member or otherwise.
• You filed articles of incorporation — you are a corporation, regardless of S-corp or C-corp tax election.
• Two or more owners, no entity filed — you are a partnership.
• A licensed professional practice — likely a PLLC or LLP, both of which Amazon names.
• A church, charity or association with tax-exempt status — the non-profit branch of the eligibility list, which explicitly covers 501(c) and 527 organizations. See Amazon Business for churches and faith organizations.
• A school district, city department or agency — the governmental branch, which covers federal, state, local and quasi-governmental bodies. See government and public sector.

The EIN question

This is the part people actually get stuck on, and it deserves a careful answer rather than a confident one.

Amazon's registration guidance asks for a tax identification number. It does not say "EIN" to the exclusion of everything else, and it names sole proprietorships as eligible entities — which would be incoherent if an EIN were mandatory, because the IRS does not require a sole proprietorship without employees to have one. For those businesses the owner's Social Security number functions as the taxpayer identification number.

What we will not do is tell you Amazon "accepts an SSN" as a blanket rule, because Amazon does not publish that sentence and we do not invent sentences. What we can say with confidence:

• Sole proprietorships are an Eligible Entity, in writing.
• The field asks for a tax identification number, which is a broader category than EIN.
• If you already have an EIN — and many sole proprietors get one purely to avoid handing their SSN to vendors — use it. It removes the question entirely.

If you do not have one, applying for an EIN through the IRS is free and usually immediate. Whether that is worth doing is a business decision, not an Amazon one.

Where the entity name really matters: tax exemption

The registration screen is low-stakes. The exemption workflow is not.

Amazon requires an exemption certificate submitted to the Amazon Tax Exemption Program to match the business name or address on the Amazon Business account. This is one of the two leading causes of rejected enrollments. If your certificate is issued to "Riverside Dental PLLC" and your Amazon account says "Riverside Dental", you have created a problem for yourself three months before you knew it existed.

So: register in the legal name that appears on your tax documents, even if your customers know you by something friendlier. The full enrollment walkthrough, including the six document types Amazon rejects, is on how to enroll in tax exemption and tax-exempt purchasing.

Does entity type affect pricing or plans?

No. Amazon's Pricing Policy attaches business-only prices and quantity discounts to items, not to buyers' legal forms. Business Prime plan pricing is a function of seat count, not entity type — see Business Prime pricing.

There is one adjacent clause worth knowing. The Pricing Policy describes distributor and negotiated pricing: you may be eligible for specific pricing on certain products if you are part of certain customer segments — Amazon gives the examples of certain wholesalers, authorized distributors of a particular brand, licensed cosmetologists, and customers with prenegotiated supplier pricing. Amazon adds that although it or its suppliers will attempt to identify eligible customers, it cannot guarantee your business will be offered this pricing even if it would otherwise qualify.

That is about your trade, not your incorporation, and it is not something you can select on a dropdown.

One-person businesses: the tier that actually matters

If you are registering as a sole proprietor or a single-member LLC, the entity dropdown is the least interesting decision you will make today. The interesting one is whether Prime Business Duo applies to you, since it is free for a one-user business account when you link a personal Amazon Prime membership — and it comes with a set of published conditions that are easy to fall foul of.
