AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A US person who can control a foreign account by instructing the bank, alone or together with another person, has signature authority and generally files their own FBAR if the accounts they own or can sign on together exceeded $10,000 at any time in the year, even with no financial interest. The listed exceptions cover officers and employees of OCC-examined banks and of companies with securities listed on a US exchange or registered under section 12(g); staff of most private companies are not covered.
In a US company with a Lagos subsidiary, the people who can approve payments on the Nigerian account are often in the US: the founder, the CFO, a finance manager. None of them owns the account. Many assume the FBAR is the company's problem. It is, but it can also be theirs personally. This guide explains why, using IRS Publication 5569 and the IRS FBAR page. It is information, not advice.
What signature authority means
Publication 5569 (Rev. 3-2022) defines it as the authority of an individual, alone or in conjunction with another individual, to control the disposition of assets held in a foreign financial account by direct communication, written or otherwise, to the bank or other financial institution that maintains the account.
- Alone or jointly. A two-signatory mandate where your approval is one of two still counts.
- Direct communication. If the bank acts on your instruction, whether by signed form, online approval or email, you have it.
- No ownership needed. The IRS FBAR page lists signature or other authority as a filing trigger in its own right, separate from financial interest.
Being able to view the account online, or preparing payments that someone else approves with the bank, is different from controlling disposition. Map what each person can actually instruct the bank to do.
The exceptions, and who they do not cover
Publication 5569 lists people with signature authority but no financial interest who generally do not need to report, including:
- An officer or employee of a bank examined by the Office of the Comptroller of the Currency.
- An officer or employee of an entity with a class of equity securities, or American depositary receipts, listed on a US national securities exchange.
- An officer or employee of an entity with a class of equity securities registered under section 12(g) of the Securities Exchange Act.
A privately held US start-up or family business fits none of these. Its US-person signatories are generally in the rules. The IRS page also notes that the filing date has been extended for certain officers and employees with signature authority but no financial interest, and refers to a FinCEN notice; check that notice to see whether it applies to you before relying on it.
A worked example
Example figures only. A Houston-based CFO is one of two signatories on her company's Lagos subsidiary account, which peaked at the equivalent of $60,000 during the year. She has no personal foreign accounts. The company is private. She has signature authority over an account that alone exceeds $10,000, so she files her own FBAR listing that account under signature authority, with no financial interest. The US parent, owning more than 50% of the subsidiary, files separately (or consolidated) for its financial interest. The Lagos-based managing director, who is not a US person, has no FBAR duty.
Records and the tax return
The IRS FBAR page says an officer or employee who reports signature authority over an employer's foreign account does not need to keep personal records of it, because the employer keeps them. The individual still needs the account details to complete the form, so agree with the company who sends what, and when, before each April.
On the individual's Form 1040, the Schedule B instructions (reviewed 30 April 2026) say to answer "Yes" to the foreign account question at line 7a if you had signature authority over a foreign account, even if you are not required to file FinCEN Form 114. The FBAR itself is not attached to the return.
Changes during the year
Because the test looks at any time in the calendar year, a person who was a signatory for only part of the year, for example a finance manager who left in June, still reports the account for that year if the threshold was met. The same applies to someone added in November. Keep a dated log of mandate changes, signed off by the bank, so each person can see which accounts they held authority over and for how long. When someone leaves, remove them from the mandate promptly and get the bank's written confirmation; the confirmation is the evidence of when their authority ended.
What to check first
- Get the bank mandate for every Nigerian account and list who can instruct the bank.
- Mark which of those people are US persons.
- Check whether the company falls within a listed exception.
- Give each US-person signatory the account details and maximum value by early in the year.
- Remove signatories who no longer need access; it reduces filings and risk.
The company's own filing is covered in FBAR for a US company's Nigerian bank account, and approval design in setting approvals and controls for payments in Nigeria.
Where Pryme fits
On a Pryme Business Account, the agents prepare work and a person approves above a set ceiling, with each action recorded, so you can show who actually controls payments. Ask your preparer how that approval structure maps to signature authority for FBAR. The Chief of Staff agent can remind signatories of the dates you set.
Questions people ask
Do I need to file an FBAR if I only have signing rights on my employer's Nigerian account?
Generally yes, if you are a US person and the accounts exceed $10,000 at any time in the year, unless your employer falls within a listed exception such as a US-listed company.
Does joint signing count as signature authority?
Yes. Publication 5569 defines it as authority alone or in conjunction with another individual.
Does a Nigerian-resident director need to file an FBAR?
The FBAR applies to US persons. A director who is not a US citizen, resident or entity has no FBAR duty.
Do I tick yes on Schedule B for signature authority only?
Yes. The Schedule B instructions say to answer "Yes" at line 7a if you had signature authority over a foreign account, even if not required to file FinCEN Form 114.
