Key takeaways
- An EIN doesn't keep your SSN out of underwriting. The processor still verifies you personally and usually pulls your credit.
- The legal name on the application has to match IRS records for the tax ID you give, or you risk mismatch notices and backup withholding.
- Forming an LLC rarely removes the personal guarantee on a merchant agreement.
- Switching from your SSN to an LLC's EIN usually means a new merchant account and two 1099-Ks for that year.
Yes. Opening a merchant account for sole proprietor businesses is routine, and you can accept credit cards without an LLC. You can apply with either your Social Security number (SSN) or an employer identification number (EIN). Either way the processor underwrites you personally, because a sole proprietorship and its owner are one legal person. Your choice of number mostly affects privacy and how cleanly your tax forms line up with your books. It matters most later, on the day you form an LLC.
Yes, You Can Get a Merchant Account as a Sole Proprietor
Processors approve sole proprietors every day, from a handyman working under his own name to a stylist renting a chair. Entity type is one of the least important things an underwriter looks at. Underwriters care far more about what you sell and how you sell it. They also weigh your expected monthly volume and average ticket size, along with your personal credit and any history with other processors.
A corporate application has a separate company to evaluate. Yours doesn't. The legal name on the account is your own name, or your name plus a registered trade name (a DBA, short for "doing business as"). When the underwriter pulls a credit file, it's yours.
How you plan to take payments shapes the application as much as your entity does:
- Contractors often collect deposits before work starts and key in card numbers over the phone. Tell the underwriter how large those deposits run and how far ahead of the job you take them. Money collected for future work is a risk factor they will ask about.
- Salon and spa booth renters are usually separate businesses from the salon that hosts them. Each renter selling their own services needs their own account. Running a renter's sales through the salon owner's terminal mixes two businesses' money under one merchant, which processors generally prohibit.
- Consultants and other professional services firms mostly bill remotely, through emailed invoices or a virtual terminal for keyed and invoiced payments. Keyed and online sales carry more fraud and chargeback risk than tapped cards, so expect questions about your contracts and refund terms.
- Retail stores that sell face to face with chip and tap readers usually present the simplest risk profile.
If you're still deciding between a full merchant account and a payment app that signs you up in minutes, our comparison of every way to accept credit card payments lays out the trade-offs.
SSN or EIN for a Merchant Account: What Processors Actually Use
A sole proprietor can run the business on an SSN alone, or get an EIN from the IRS and use it as the business tax ID. Apply directly on IRS.gov, and be wary of third-party sites that charge to file the form for you.
Many owners assume an EIN keeps their Social Security number out of the application. It doesn't. Even with an EIN listed as the business tax ID, the processor still collects your SSN, because it has to verify your identity and pull your credit. Your personal guarantee is tied to that number as well. An EIN changes which number appears on tax forms. Who gets underwritten stays the same.
| Apply With Your SSN | Apply With an EIN (Sole Proprietor) | |
|---|---|---|
| Who the processor underwrites | You | Still you |
| Personal credit check | Usually | Usually |
| Name and number on your 1099-K | Your name and SSN | The name and EIN on your IRS record |
| What you give clients on a W-9 | Your SSN | Your EIN |
| If you hire employees | May change what tax ID you need; check IRS guidance | Confirm with IRS guidance before your first hire |
| Carries over to a new LLC | No | Generally no; confirm with your tax preparer |
Privacy outside the processor is the practical case for an EIN. Contractors and consultants hand W-9s to clients constantly, and with an EIN your SSN isn't sitting in a dozen clients' files. Hiring is the other trigger. Hiring employees can change what tax ID you need, so check IRS guidance before your first hire.
Match the Legal Name to the Number
Whichever number you use, the legal name on the application has to match the IRS record for that number. With an SSN, that's your personal name exactly as Social Security has it. An EIN uses the name printed on your EIN confirmation letter.
A common mistake is entering only the trade name ("Ridgeline Repairs") as the legal name next to a personal SSN. When the processor's records don't match the IRS's, you can get mismatch notices and eventually backup withholding, where the processor holds back part of your deposits and sends it to the IRS. Put your legal name in the legal-name field and the trade name in the DBA field.
Documents Sole Proprietors Need for Approval
Requirements vary by processor and by how risky your business looks. Most sole proprietor applications ask for:
- A government-issued photo ID
- Your SSN, plus your EIN and its confirmation letter if you use one
- A voided check or bank letter for the deposit account
- Your DBA filing, if you operate under a trade name (assumed-name rules vary by state and county)
- Any license your trade requires, such as a contractor's or cosmetology license
- For online sellers, a website or business page that shows how to reach you and states your refund policy
- Recent processing statements, if you're switching from another provider
Higher-volume or higher-risk applications may also need bank statements or a tax return.
Of everything on that list, the deposit account trips people up most often. Some processors accept a personal checking account for a sole proprietor, while others require one opened as a business. Either way, the name on that account should match the name on the application. Our guide to what processors check on your business bank account covers the details. If you've already been declined once, read common reasons merchant accounts get denied before you reapply.
Personal Guarantees: An LLC Doesn't Take Your Name off the Contract
A merchant agreement makes the merchant responsible for chargebacks and refunds. It also covers fees, plus any network fines the processor pays on the merchant's behalf. As a sole proprietor, that merchant is you, with no separation between business money and personal money.
Many owners form an LLC expecting it to shield them here. Usually it won't. Small business merchant applications typically require the owner to sign a personal guarantee regardless of entity type, so if the LLC can't cover a wave of chargebacks, the processor can pursue the guarantor. An LLC may protect you from other kinds of liability. Whether it does is a question for an attorney, and it isn't a reason to expect a different merchant contract.
Your processing history follows you personally too. Processors report certain terminated merchants to a shared industry database that lists the business's principals along with the business itself. A termination under your sole proprietorship stays visible when you apply later as an LLC.
How 1099-K Reporting Works When Your SSN Is on the Account
Your processor files Form 1099-K with the IRS each year and sends you a copy. It reports gross card sales under whatever name and tax ID sit on your merchant account. Gross means the total before any deductions. Refunds and chargebacks are still in it, and so are your processing fees, which is why the figure always runs higher than your deposits.
The reporting thresholds that make the news mostly concern payment apps and online marketplaces, and they have changed more than once. Card sales through a traditional merchant account can be treated differently from payment app transactions, so don't assume a headline threshold applies to you. Confirm the current rules for your account on IRS.gov or with your tax preparer.
For a sole proprietor using an SSN, the 1099-K goes to you personally. That income belongs on your business tax return next to cash and check sales. Reconciling the gross figure to your books is where the real work lies, and our guide on reconciling Form 1099-K before tax time walks through it step by step. Treat this section as general information, not tax advice.
Forming an LLC Later Means a New Merchant Account
Your merchant account belongs to a specific legal entity and tax ID. Forming an LLC creates a new legal person. In most cases that means a new application and a new merchant ID, not a quick edit to the old account. Processors handle the details differently, so ask before you assume anything carries over.
A clean switch usually runs in this order:
- Form the LLC and get its EIN.
- Open a bank account in the LLC's name.
- Apply for a merchant account under the LLC, using your current processing statements as history.
- Move sales to the new account once it's live.
- Keep the old account open for a while to process refunds on earlier sales and respond to chargebacks.
- Close the old account in writing once those windows have passed.
Don't run LLC sales through the old sole proprietor account. Doing so means the processor settles another entity's money under your SSN, which is exactly the mismatch underwriting exists to prevent. Our article on when to tell your payment processor about business changes covers timing.
A Worked Example: Switching Mid-Year
This example is illustrative. Take a hypothetical handyman doing business as Ridgeline Repairs under his SSN. Midway through the year he forms a single-member LLC and applies for a merchant account under the LLC's EIN. He plans to switch at the start of July. Approval takes longer than he expected, though, and the new account doesn't go live until the second week of the month, so he keeps running cards on the old account until then.
Come January, he should expect two 1099-Ks. One, under his SSN, covers every card sale that settled on the old account, including those early-July sales. The other, under the LLC's EIN, covers only what ran after the new account went live. Neither form shows his total for the year.
If the LLC is treated as a disregarded entity for tax purposes, both forms typically feed the same business return, and his preparer adds them together to reach gross card sales for the year. His preparer needs both forms. Hand over only one, and the IRS sees income it can't match to his return.
What decides the split is the date the new account actually started processing, not the date he planned. Sales before that day land on the old form. Recording the real cutover date in his books lets his preparer reconcile the two forms without guesswork.
Decide Which Name and Number Belong on the Account First
Before you fill out an application, settle two things: the legal name and tax ID the account will carry, and whether you plan to form an LLC soon. If an LLC is likely within a few months, forming it first can spare you a second application and a split year of 1099-Ks. If you're staying a sole proprietor, decide whether you want an EIN for privacy, then make sure your bank account and application show the same legal name.
