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
Interest on dollar savings in Nigeria is taxed like naira interest: from 1 January 2026, banks deduct 10% withholding tax on all foreign-currency deposit interest, in line with the Nigeria Tax Act 2025, as reported from bank notices. Income from the domestic FGN US dollar bond is exempt from personal income tax, and dollar fund returns follow the fund's own tax treatment.
The rule in one line
BusinessDay reported on 1 January 2026 that Nigerian banks would deduct 10% withholding tax (WHT) on interest earned on foreign-currency (FCY) deposits from that day, "aligning with the Nigeria Tax Act, 2025". Access Bank notified its customers, and the article states that "the deduction applies to all FCY deposit interest". The bank deducts the tax before crediting you and remits it to government.
The currency of the deposit does not change the principle. Naira savings interest already has 10% withheld at many providers: Kuda's help centre says 10% WHT is applied to accrued interest, and Moniepoint's savings pages describe 10% tax withheld at maturity.
Worked example
Example only. You hold $8,000 in an interest-paying dollar account at an example rate of 2% a year.
- Gross interest for the year: $8,000 × 2% = $160.
- Withholding tax at 10%: $160 × 10% = $16.
- Net interest credited: $160 − $16 = $144, an effective 1.8% a year.
The tax is taken in the currency of the deposit, so the deduction is in dollars. Your statement should show the gross interest and the tax line separately; if it does not, ask the bank for a breakdown.
How different dollar products are treated
| Product | What the sources say about tax |
|---|---|
| Bank domiciliary or dollar savings account | 10% WHT on FCY deposit interest from 1 Jan 2026 (BusinessDay) |
| Domestic FGN US dollar bond | Income exempt from companies income tax, personal income tax and capital gains tax (DMO FAQs, Aug 2024) |
| Dollar mutual funds | Not stated on the fund pages we read; ask the fund manager how distributions are taxed |
| App dollar products | Ask the app whether it deducts tax and shows it on statements |
| US stocks through an app | Bamboo, for example, lists 30% US withholding on dividends; that is a US tax, not the Nigerian deposit WHT |
BusinessDay's report also covered withholding on interest from Treasury bills, bonds, commercial papers and similar securities, noting that FGN bonds and CBN OMO bills were exempt. That part concerns short-term securities, not bank deposits, and the article did not say how naira deposit interest is treated, so we rely on the providers' own pages for that.
What to keep and check
- Keep your annual statements showing gross interest and tax deducted. They are your evidence if NRS or your state tax office asks.
- Check the tax line against the rate: 10% of the interest, not of your balance.
- If you earn other foreign income, such as freelance pay, that is a separate question; see do Nigerian freelancers pay tax on dollar income.
- If you think tax was deducted wrongly, ask the bank for its computation first, then seek advice.
When the tax is deducted
Withholding happens when interest is paid or credited, not when you open the account. In practice:
- Monthly or quarterly interest: tax is taken from each credit, so you see a smaller amount each time.
- Interest at maturity: on a fixed-term deposit, tax is taken from the full interest when the term ends. Kuda describes 10% WHT being deducted from accrued interest before payout at maturity on its naira fixed savings, for example.
- Early break: if you break a deposit early and lose some interest, tax applies to the interest you actually receive.
If you hold dollar savings with more than one bank, each one deducts separately on its own interest. There is no single annual deduction across banks.
Interest versus currency gains
The withholding tax covers interest. A rise in the naira value of your dollars because the naira weakened is a different matter: it is not interest, and no bank deducts withholding tax on it. How such gains are treated, if you later sell the dollars, is a question to put to NRS or an adviser; we did not find a source that addresses it for individual savers.
Does tax change which product to choose?
It can at the margin. Two dollar products with the same headline rate can leave different net returns if one is tax-exempt. The FGN dollar bond's exemption is a real advantage for those who can meet its $10,000 minimum. For small balances in near-zero-interest domiciliary accounts, the tax hardly matters because there is little interest to tax. Compare after-tax, after-fee figures, as covered in how dollar savings rates are set.
Example comparison
Example only. On $10,000 for a year, a 3% taxable deposit pays $300, minus $30 WHT, leaving $270. A tax-exempt bond paying 3% would leave the full $300. The $30 difference is the tax.
Where Pryme fits
Pryme does not pay interest on USD balances, so there is no interest to withhold on them. For naira savings, Savings Boxes show their terms in the app. Pryme customers can generate a verifiable statement with VerifyDoc.ai, which anyone can check is genuine and unaltered; see receipts and statements.
