Yes, you can add another person to your business checking account, but the process and permissions depend on your bank and account structure

Most banks let you add a co-owner, authorized user, or signer to a business checking account. The difference matters: a co-owner has equal legal claim to the account and can make major decisions; an authorized user or signer can withdraw and deposit money but typically cannot close the account or change its terms. Your bank's process or agreement will specify which role you are creating.

The person you add will need to provide identification and possibly a Social Security number or EIN. Some banks require both of you to visit a branch in person; others allow you to add someone online or by mail. The timeline is usually one to five business days after the bank receives all documents.

Key Takeaways

  • Co-owners and authorized users have different legal rights—co-owners can close the account or change terms, while authorized users typically cannot.
  • You will need the other person's legal name, date of birth, and identification; some banks also require their Social Security number or EIN.
  • Many banks require both account holders to sign documents in person at a branch, though some allow remote setup.
  • The added person will usually receive their own debit card and online access within one to five business days.

What your bank needs from the person you are adding

Before you start, gather the other person's information. Banks typically ask for a government-issued photo ID (driver's license, passport, or state ID), legal name exactly as it appears on that ID, date of birth, and either a Social Security number or EIN if they are a business entity. Some banks also request a current address and phone number.

If the person you are adding lives far away or cannot visit a branch, call your bank first. Some institutions mail documents for remote signings; others use notarized paperwork or video verification. A few banks require both signers to appear in person, which means you may need to schedule a time when you can both be at the same branch.

The difference between co-owner, authorized user, and signer

A co-owner (sometimes called a joint owner) has equal legal rights to the account. Both of you can withdraw money, deposit funds, write checks, and make decisions about the account—including closing it or removing the other person. If one co-owner dies, the surviving co-owner typically inherits the full balance. Co-ownership is common when spouses or business partners want equal control.

An authorized user or signer can conduct daily transactions—deposits, withdrawals, transfers, and checks—but cannot close the account, change the account name, or remove themselves. They have no legal ownership stake. This role is useful when you want to give an employee or manager access without giving them control over the account itself. The original account holder remains the sole owner and can revoke access at any time.

Some banks use different terminology. Ask your bank directly which role you need before you submit paperwork, because switching from one to another later may require closing and reopening the account.

How to add someone through your bank

Start by contacting your bank—call the number on your statement, visit a branch, or log into online banking to see if there is an option to add a user. Many banks have a form called "Add Authorized User" or "Add Account Holder" that you can request or read from their website.

Fill out the form with the other person's information and your own signature (and theirs, if required). Some banks let you upload documents through online banking; others ask you to mail or fax them. A few require both of you to sign in front of a bank employee at a branch. Once the bank receives all documents and verifies the information, they will send confirmation—usually by mail or email—and the new person's access will set up within one to five business days.

If you use an online-only bank (like Chime, Mercury, or Wise), the process is usually faster and entirely digital. You may be able to add someone from your phone or computer in minutes, though the bank will still verify their identity before granting access.

What happens after someone is added

Once the bank confirms the addition, the new person will receive a debit card in the mail (if they requested one) and can log into online banking using credentials the bank sends them. They can when ready see the account balance, transaction history, and make transfers. If you set up any spending limits or restrictions, those will explore to them as well.

You remain responsible for all activity on the account, even if the other person makes a transaction you did not authorize. If you suspect fraud or want to remove someone later, contact your bank when ready. Removing an authorized user is usually faster than adding one—often a phone call or online request—and takes one to three business days.

When a bank might refuse to add someone

Banks run background checks and verify identity before adding a new person. They may decline if the person has a history of fraud, unpaid debts to that bank, or if their identity cannot be verified. Some banks will not add someone who does not have a U.S. address or Social Security number, though policies vary.

If your bank refuses, ask why in writing. If the reason is a credit or fraud issue, the person you wanted to add may be able to dispute it or wait a set period before reapplying. If the reason is a policy (like requiring U.S. residency), you may need to switch banks or use a different account structure, such as a power of attorney or a separate account.

Frequently Asked Questions

Can I add someone without them being present?

It depends on your bank. Some allow remote additions with notarized documents or video verification; others require both signers to visit a branch in person. Call your bank to ask what they accept before gathering documents.

What if the person I want to add does not have a Social Security number?

Banks vary. Some accept an ITIN (Individual Taxpayer Identification Number) or EIN instead; others require a Social Security number. A few will not add someone without one. Contact your bank to ask what alternatives they accept.

Can I add someone and then remove them later?

Yes. Removing an authorized user is usually faster than adding one—often a phone call or online request. Removing a co-owner is more complicated and may require both signatures or a trip to the branch, depending on your bank's rules.

Will the new person see my personal tax returns or other documents?

No. They will see the account balance, transactions, and statements, but not documents you have uploaded elsewhere or tax records stored outside the account. However, they can see every deposit and withdrawal on the account itself.

What if I want to add someone but keep them from seeing the full balance?

Most banks do not offer that option. Anyone with access to the account can see the balance. If you need to limit what someone sees, you may need to set up a separate account or use a different structure, like a power of attorney for specific transactions only.
