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
Most Nigerian banks need you to hold an account with them, usually with a BVN, before you can book a fixed deposit, and the rate is agreed at booking rather than published. For a US resident, the interest is part of worldwide income, Nigerian withholding tax may be deducted first, and the account counts towards FBAR and possibly Form 8938.
A fixed deposit in Nigeria is simple at home: you lock money for a set tenor and the bank pays interest at the end. From the US it gets more layered. You have to satisfy the bank's account-opening rules from abroad, decide between naira and dollars, and then report the interest and the account itself to the IRS and FinCEN. Here is what the banks' own pages say, and what the US side asks of you. Tax points are information, not advice.
What Nigerian banks say about fixed deposits
| Bank (own page) | Tenor | Rate | Early exit and other terms |
|---|---|---|---|
| Zenith Bank FAQs | Minimum 30 days | Agreed at booking | Booked and liquidated by signed letter of authority; simple interest; 10% withholding tax |
| Standard Chartered Nigeria | 30 to 365 days (USD up to 360) | Not shown on page | Naira and foreign currency; early liquidation forfeits "20% or more" of interest; existing account holders aged 18+ |
None of these pages publishes a fixed deposit rate, so any figure you see online is a snapshot. Ask the bank for the rate in writing on the day you book, and ask what happens at maturity: Standard Chartered, for example, says deposits roll over automatically for a similar tenor at the "prevailing system rate" unless you instruct otherwise. Zenith's FAQs say you can open an account online from abroad if you have a BVN. If you do not, see the NRBVN guide.
Naira or dollar deposit?
A naira deposit usually pays a higher nominal rate, but you carry currency risk: if the naira weakens against the dollar over the tenor, your dollar result shrinks. A domiciliary (dollar) deposit removes that risk but pays less. From 1 January 2026, banks began deducting 10% withholding tax on all foreign-currency deposit interest, according to BusinessDay's report of an Access Bank notice citing the Nigeria Tax Act 2025. Our currency-adjusted yield comparison shows how quickly depreciation can wipe out a naira premium.
Worked example (illustrative figures)
Tunde books ₦10,000,000 for 365 days at an example rate of 18% simple interest. Gross interest is ₦1,800,000. If 10% withholding tax is deducted, ₦180,000 goes to the tax authority and ₦1,620,000 is credited. On his US return he reports the gross interest converted to dollars, and may be able to claim a foreign tax credit for the ₦180,000 if it qualifies.
The US side: three separate obligations
- Income tax. IRS Publication 54 says US citizens and residents are generally taxed on worldwide income, expressed in US dollars. Interest from a Nigerian deposit is reported like US bank interest.
- Schedule B. Its instructions require a Schedule B if taxable interest is over $1,500, and also whenever you had a financial interest in a foreign account. Line 7a asks about foreign accounts.
- FBAR and Form 8938. If all your foreign accounts together exceeded $10,000 at any time in the year, an FBAR is due. Form 8938 applies above higher thresholds (for a single filer in the US, more than $50,000 on 31 December or $75,000 at any time).
On credits: the IRS foreign tax credit page says the credit is generally for foreign income taxes, and that the amount withheld is not necessarily the amount that qualifies. Keep the bank's withholding tax certificate or the line on your statement showing what was deducted. More on interest from Nigerian government paper is in our guide on T-bill interest and US tax.
Records worth keeping from day one
US reporting is far easier if you collect the paperwork as you go rather than at tax time. For each deposit, keep the booking confirmation showing amount, tenor and agreed rate; the maturity advice showing gross interest and any tax deducted; and a statement showing the highest balance in the calendar year, which you need for the FBAR. Note the date interest was credited, because your preparer needs it to place the interest in the right tax year: a 365-day deposit booked in March pays out in the following calendar year, and if the bank pays interest upfront, as Standard Chartered offers, the timing is different again. Finally, write down the exchange rate you used to convert each figure to dollars, so your preparer can follow your workings and you can repeat them next year.
What to check first
- Whether you can open the account remotely, and which documents the bank needs (BVN, ID, proof of address).
- The exact rate, tenor and early-exit penalty, in writing.
- Whether interest is paid upfront or at maturity, and what happens on rollover.
- Whether withholding tax will be deducted, and how you get proof of it.
- Deposit insurance: NDIC cover applies up to the applicable limit for each insured bank.

Questions people ask
Can I open a Nigerian fixed deposit while living in the US?
Often yes, if you already have an account with that bank or can open one remotely. Zenith's FAQs say online account opening from abroad works if you have a BVN. Each bank sets its own documents.
Is interest on a Nigerian fixed deposit taxable in the US?
For US citizens and residents, yes: worldwide income is generally taxable. Report the gross interest in dollars and consider a foreign tax credit for qualifying Nigerian tax withheld.
Do Nigerian banks deduct tax on fixed deposit interest?
Zenith's FAQs mention 10% withholding tax on fixed deposits, and from 1 January 2026 banks deduct 10% on foreign-currency deposit interest, as reported by BusinessDay.
What if I break a fixed deposit early?
Banks set their own penalty. Standard Chartered says early liquidation forfeits 20% or more of the interest. Ask your bank before booking.
