Authorized signers on a business bank account are the people the bank will accept instructions from: signing checks, withdrawing funds, often changing the account. Keep the list short, tie it to a board or owner resolution, remove leavers on their last day, and compare the bank's own signer list with your approved list at least once a year.
What can an authorized signer on a business bank account do?
An authorized signer is a person the account holder has named to the bank as able to act on the account. Depending on the bank's agreement, a signer can sign checks, withdraw cash, request transfers and sometimes change account details. The bank pays items a signer approves, so the signer list defines who can move the company's money.
Signer is not the same as owner
The account belongs to the business, not to the signer. A bookkeeper who signs checks has no claim to the funds. But from the bank's side, a signer's instruction is the company's instruction. If a valid signer writes a check to themselves, the bank generally has no reason to refuse it. That is why the signer list is a control in its own right: the bank cannot protect the company from someone the company told it to trust.
Signer powers vary by bank
Some banks treat every signer as having full authority over the account. Others let the company limit a signer to certain actions or amounts. Read the account agreement and the signature card, because the limits a company sets in its own policy mean nothing to the bank unless the bank has them on file.
Online access is a separate list
Online banking users are often set up separately from signers. A person can have online access to send wires without being on the signature card, and a signer can have no online access at all. Treat the two as separate lists and review both. Setting up roles in the online system is covered in online banking user permissions and approval rules.
Choosing authorized signers for a company account
The best authorized signers are people senior enough to answer for a payment and far enough from the books that they cannot hide one. Most small companies need two or three signers: an owner or officer, a second officer or board member, and sometimes a backup for absences. Bookkeepers who record transactions or reconcile the account should usually not sign.
Who should sign
- An owner, president or chief financial officer. Someone with authority over spending and accountability for it.
- A second officer or a board member, so payments can still go out when the first signer is away.
- A backup signer in larger organizations, used only when the others are unavailable.
Who should not sign
- The person who reconciles the account. A signer who also reconciles can write a check and then explain it away on the reconciliation.
- The person who records cash receipts. Combining custody of incoming money with the power to withdraw it removes a natural check. The steps that keep receipts separate are laid out in cash receipts internal controls from mail to deposit.
- Anyone with custody of blank check stock who can also print checks. Locked storage and logs help, as described in check stock security, but the cleaner fix is keeping signing and stock apart.
- Family members of a signer who also work in finance, in a small company where they could approve each other's payments.
How many signers
More signers mean more people who can move money alone. Fewer signers mean payments stall when someone is on leave. Two is the minimum for continuity. Beyond three, ask what each additional signer adds.
Board resolutions and bank signature cards
A board resolution is the company's written decision naming who may sign and what they may do. The signature card or signer form is the bank's record of that decision. The bank relies on the card, so the resolution and the card must say the same thing, and both must be updated whenever a signer changes.
What the resolution should say
A banking resolution for a corporation, or a similar written consent for an LLC or partnership, typically records:
- The bank and the accounts the resolution covers.
- The names and titles of the authorized signers.
- Any limits, such as two signatures required above a set amount.
- Who may add or remove signers in the future.
- The date it was adopted and who certified it.
Banks often supply their own resolution form. Use it if they require it, but keep a copy in the company's minute book along with the board minutes that approved it.
What the bank records
The signer form records each person's name, identification details and specimen signature. Banks may also ask for documents showing the company exists and who controls it. When the company sends a new resolution, ask the bank for written confirmation that the signer record was updated. A resolution the bank never processed changes nothing.
Dual signature requirements
Many resolutions require two signatures above a threshold, but do not count on the bank to enforce it, and electronic payments bypass signatures entirely. What to ask the bank, and how to keep the rule useful as an internal approval step, is covered in how banks treat a two-signature check requirement.
Removing an authorized signer when someone leaves
A departed employee should come off the signer list on their last day, along with their online banking access, cards and tokens. That takes a new resolution or signer form, delivered to the bank before the person leaves when possible, and a written confirmation from the bank that the change is done.
Steps on departure
- Prepare the paperwork in advance. For a planned departure, have the new resolution signed before the last day.
- Disable online access first. Online access can be removed in minutes by the company's administrator, while signer changes can take the bank days.
- Deliver the signer change to the bank and ask for confirmation in writing.
- Collect bank cards, tokens and check stock the person held.
- Notify the bank's relationship contact if the departure is contentious, so staff know to question instructions from that person.
- Review the next statement closely for checks dated before the departure that clear afterward.
Departures that are not terminations
A signer who changes roles, such as an officer who becomes a consultant, should still come off the account if their new role does not need signing power. Titles in the resolution help here: if signing authority attaches to "the treasurer", a change in who holds that office should trigger an update.
When the departed signer was the only signer
A company whose sole signer leaves, dies or becomes unreachable can find its account frozen until it proves who now has authority. Naming at least two signers avoids that. If it happens anyway, the bank will usually want governing documents and a new resolution from whoever controls the company.
How often should the authorized signer list be reviewed?
The authorized signer list should be reviewed at least once a year and whenever an officer, owner or finance employee changes. The review compares the bank's own list of signers and online users with the list the company approved. Someone who is not on either list should perform it, such as a board member or an outside accountant.
Get the list from the bank
Do not review the company's copy of the resolution. Ask the bank for its current signer record and its list of online banking users for each account. Old signers often survive on bank records long after the company's own files were updated.
An example review log
The log below is an example of an annual review for one operating account. Names and dates are made up.
| Person | On approved list | On bank signer record | Online user | Finding | Action |
|---|---|---|---|---|---|
| Dana Ruiz, President | Yes | Yes | Approver | None | None |
| Sam Okafor, Treasurer | Yes | Yes | Approver | None | None |
| Lee Park, former Controller | No (left 2026-02-14) | Yes | Initiator | Still a signer and still an online user | Remove both; confirm in writing |
| Jo Hart, Bookkeeper | No | No | Initiator | Online initiator, not a signer | Acceptable under policy; confirm she cannot approve |
Record the result
Keep the review log, the bank's list and the confirmation of any changes. That bundle is the evidence an auditor will ask for. Small teams that already keep monthly reconciliation workpapers in one place can file the review there too; reconciliation software for small business covers ways to keep those records together.
Signer arrangements that defeat the control
Some signer setups look careful on paper but let one person move money alone: pre-signed blank checks, signature stamps kept by the bookkeeper, signers who share their online credentials, and dual-signature rules the bank never enforces. Each one turns a two-person control into a one-person control without anyone deciding to.
Pre-signed checks
A signer who leaves signed blank checks for the bookkeeper "in case something comes up" has handed over the signature. Replace the habit with an online payment that the signer approves from wherever they are.
Signature stamps and electronic signatures
A stamp or a stored signature image in check printing software works for anyone who can reach it. If the company uses one, lock it up, log its use and have the signer review a list of every check printed with it.
Shared credentials
A signer who gives a staff member their online banking password has added an unapproved signer. The bank's logs will show the signer's name, which also makes it hard to prove later who sent a payment.
Rubber-stamp signing
A signer who signs whatever is put in front of them provides little protection. Ask signers to look at the invoice or approval behind each check. A short glance at support stops more than a signature alone.
The monthly statement as the backstop
Even a well-run signer list cannot prevent every misuse. The monthly reconciliation, reviewed by someone other than the signer, is where an improper check or transfer surfaces. Tools such as PreciseBankFlow can read each statement, prove it foots and flag duplicate or unmatched items, which gives the reviewer a short list of lines worth tracing back to who approved them.
