Most people don't need an EIN to open a personal checking account

If you're opening a checking account for yourself, your Social Security number is what the bank will ask for. Banks use your SSN to verify your identity and check your banking history through ChexSystems or Early Warning Services. An EIN (Employer Identification Number) is a tax ID issued by the IRS, and it's meant for businesses, trusts, and certain other entities — not for individual account holders.

You only need an EIN if you're opening an account in the name of a business, partnership, corporation, nonprofit, or estate. If the account is in your personal name alone, your SSN is sufficient and is what the bank expects to see.

Key Takeaways

  • A personal checking account requires only your Social Security number, not an EIN.
  • An EIN is required only when opening a business, nonprofit, partnership, or trust account in that entity's name.
  • Banks verify personal accounts using SSN and ChexSystems; they verify business accounts using EIN and business registration documents.
  • If you're self-employed but operate as a sole proprietor, you can use your SSN for a personal account that receives business income.
  • You cannot use an EIN in place of an SSN for a personal account, even if you have both.

When you do need an EIN for a business account

If you're starting a business and want to open a checking account under the business name, the bank will require an EIN. This applies whether you're forming an LLC, S-corporation, C-corporation, partnership, or nonprofit. The bank needs the EIN to verify that the business entity exists and to report interest and other account activity to the IRS under the correct tax ID.

You'll need to bring the EIN itself (which the IRS sends you by mail after you request it) along with documentation showing the business is registered. This might be articles of incorporation, an LLC formation certificate, a partnership agreement, or a nonprofit information letter. Different banks ask for different documents, so call ahead to ask what yours requires.

If you're a sole proprietor — meaning you're self-employed but haven't formed a separate business entity — you don't need an EIN. You can open a personal checking account using your SSN and deposit business income into it. Many sole proprietors do this. However, some choose to get an EIN anyway to keep business and personal finances more separate, and banks will allow this.

How to get an EIN if your business needs one

You can request an EIN from the IRS for free through their website at irs.gov, by phone at 1-800-829-4933, or by mailing Form SS-4. The online method is fastest — you can get your EIN immediately after you submit the form, and the IRS will email it to you right away. By phone, you receive it during the call. By mail, it takes about four weeks.

You'll need to have your business structure decided before you apply (sole proprietor, LLC, corporation, etc.) and know the business's start date and primary activity. Have your SSN ready. The form takes about 15 minutes to complete online.

What happens if you try to open an account without the right ID

If you walk into a bank with an EIN but no SSN and try to open a personal account, the bank will turn you down. Personal accounts are tied to individuals, and the bank has no way to verify your identity or run a background check using only an EIN. The reverse is also true: you cannot use an SSN to open an account in a business entity's name.

If you're opening a business account and don't have an EIN yet, most banks will not open the account until you provide one. Some larger banks may let you open it with a temporary EIN receipt (the paper the IRS gives you when you apply by phone or in person), but this is not standard. It's faster to get the EIN first, then open the account.

Special cases: trusts, estates, and joint accounts

If you're opening an account for a revocable living trust, the bank may ask for an EIN, but many will accept your SSN instead since you're the trustee and the account is still under your control. Ask the bank what they require before you apply. Some banks treat trust accounts like personal accounts; others treat them like business accounts.

For an irrevocable trust or an estate account (opened after someone dies), you will need an EIN. The executor or trustee should request one from the IRS using Form SS-4, checking the box for "estate" or "trust" as appropriate. This usually takes a few weeks, so plan ahead if you're settling an estate.

A joint personal account between two people requires only the SSNs of both account holders. No EIN is needed, even if one person is self-employed or runs a business.

Documents to bring when you open your account

For a personal checking account, bring a government-issued photo ID (driver's license, passport, or state ID) and your SSN. Some banks also ask for a second form of ID or proof of address, such as a utility bill or lease.

For a business checking account, bring the EIN (or the EIN receipt if you just applied), your personal photo ID, and the business formation documents the bank requests. Call your bank first to ask what documents they need — this varies by bank and by business type. Having everything ready before you go in speeds up the process.

Frequently Asked Questions

Can I use my EIN instead of my SSN to open a personal account?

No. Banks require a Social Security number for personal accounts because it's tied to your credit history and identity verification systems. An EIN is a business tax ID and cannot substitute for an SSN on a personal account.

I'm self-employed. Do I need an EIN to open a checking account?

Not if you operate as a sole proprietor. You can open a personal checking account using your SSN and deposit business income into it. Getting an EIN is optional for sole proprietors but can help you keep business and personal finances separate.

How long does it take to get an EIN for my business account?

Online requests are processed immediately. Phone requests are completed during the call. Mail requests take about four weeks. Once you have the EIN, most banks can open your business account the same day.

What if the bank asks for an EIN but I only have an SSN?

This usually means the bank is treating your account as a business account. If you're opening a personal account, clarify with the bank that it's for personal use. If it's truly a business account, you'll need to get an EIN before the bank will proceed.

Do I need an EIN to add a business account to my existing personal checking account?

No. You cannot add a business account to a personal checking account. They are separate accounts with different IDs. If you want a business account, you open a new one at the same bank or elsewhere, and it will require an EIN if it's in the business entity's name.
