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
Yes, it can. A US person must file an FBAR if they have a financial interest in, or signature or other authority over, foreign accounts worth more than $10,000 combined at any time in the year. Being a joint owner of a parent's Nigerian account is a financial interest, and being a signatory who can instruct the bank alone or together with the parent is signature authority, so the account counts in your total and is reported.
Why children abroad end up on parents' accounts
Many Nigerians in the US are added to a parent's account in Lagos or Owerri so they can help with bills, sign if the parent is ill, or manage pension and rent money. Sometimes the account is opened jointly; sometimes the child is added to the mandate as a signatory. For US purposes, both can bring the account into your FBAR.
Financial interest or signature authority?
- Financial interest
- You are an owner of record or hold legal title, alone or jointly. A joint account with your mother is a financial interest for you.
- Signature authority
- FinCEN defines it as the authority of an individual, alone or in conjunction with another, to control the disposition of assets in the account by direct communication with the financial institution.
- Neither
- You only send money in, or the parent tells you the balance. Paying into an account does not give you authority over it.
The words "in conjunction with another" matter. If the bank's mandate says withdrawals need both your signature and your father's, you still have signature authority, even though you cannot act alone.
How it changes your FBAR
- The account counts towards the $10,000 aggregate test with your own accounts.
- For a joint account, FinCEN says each joint owner reports the entire value of the account, not a share, and gives the number of joint owners (an estimate is allowed).
- For a signature-only account, you report it in the part of the form for accounts where you have authority but no financial interest, with the owner's details.
- The value is the account's maximum during the year, converted at the Treasury rate for the last day of the year.
A worked example
Example only. The rate is illustrative. Ifeoma, a nurse in Dallas, has her own Nigerian savings account with a maximum of ₦3,000,000 in the year. She is a joint holder on her mother's account, which peaked at ₦9,000,000 when rent came in. At an illustrative ₦1,500 = $1:
| Account | Maximum value | Dollars | How reported |
|---|---|---|---|
| Ifeoma's savings | ₦3,000,000 | $2,000 | Her own account |
| Joint with mother | ₦9,000,000 | $6,000 | Joint account, full value, 1 other owner |
| Total | $8,000 | Under $10,000: no FBAR on these figures |
If the mother's account had peaked at ₦13,000,000 ($8,667, rounded up), the total would be $10,667 and Ifeoma would file, reporting the full value of the joint account, even though most of the money belongs to her mother.
Things the FBAR does not change
- Ownership and tax. Reporting an account does not make the money yours for income tax. Interest on your mother's money is not your income because you are a signatory. If you are a joint owner, who owns the interest depends on the facts; ask a preparer.
- Form 8938. Form 8938 has its own rules on what is reported and much higher thresholds. Compare the two in the IRS chart, and see Form 8938 and FBAR for Nigerian accounts.
- Gifts. Money you put into a parent's account is a gift; the IRS gift tax rules apply, not the FBAR.
Powers of attorney and mandates
A power of attorney can work the same way. If your parent has given you a power of attorney that the Nigerian bank has registered, and you can now instruct the bank directly to move money, that looks like control by direct communication with the bank, which is the FinCEN test. A power of attorney that the bank has never seen, kept in a drawer for emergencies, is a different matter, because until it is lodged you cannot use it to instruct the bank. Check what the bank's records actually show.
Questions to ask the Nigerian bank
- Am I listed as a joint owner, or only as a signatory on the mandate?
- Can I instruct transfers alone, or only with my parent's signature?
- Is a power of attorney in my name registered on the account, and from what date?
- Can you provide statements for January to December so I can find the highest balance?
Practical steps
- Ask the Nigerian bank for the account mandate, so you know whether you are a joint owner or a signatory.
- Get statements for the full calendar year to find the maximum value.
- Keep records for five years, as the IRS requires for FBAR.
- If you no longer need authority, ask the bank in writing to remove you, and keep the confirmation. The FBAR follows the authority you had during the year.
- Remember Schedule B on your tax return asks whether you had a financial interest in or signature authority over a foreign account.
If you have missed years, read late FBAR without penalty: the delinquent procedure. This is general information, not tax advice.
Where Pryme fits
Some families choose a separate arrangement instead of a joint account. A parent can hold their own Pryme account and set up a Personal Assistant to prepare bills and payments for their approval, while you send money to them. Whether a given setup gives you signature authority depends on its terms, so check before you assume.
Questions people ask
Do I need to file FBAR if I am a signatory on my parent's account in Nigeria?
If the account, added to your other foreign accounts, takes the total over $10,000 at any time in the year, yes. Signature authority counts even when you must sign together with your parent.
Do I report the full balance of a joint account with my mother?
Yes. FinCEN's instructions say each joint owner reports the entire value of the account.
Does being on my parent's account mean I pay tax on their interest?
Not because of signature authority alone. FBAR is a reporting rule; income tax depends on who owns the money. Ask a preparer about joint ownership.
How do I stop having to report my parent's account?
Ask the bank in writing to remove you from the mandate and keep the confirmation. You still report for any year in which you had authority.
