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
For a US citizen, green card holder or other US tax resident, a Nigerian money market fund is usually a passive foreign investment company (PFIC), because almost all of its income is interest. The IRS Form 8621 instructions make a fund a PFIC if 75% or more of its gross income is passive or at least 50% of its assets produce passive income. That brings a separate Form 8621 for each fund, possible interest charges on distributions and gains, and record-keeping in dollars from the first naira you invest.
Why a naira money market fund trips the PFIC test
A money market fund in Nigeria pools savers' naira and places it in Treasury bills, commercial paper and bank deposits. Money market funds are the largest part of the Nigerian mutual fund market: SEC weekly data reported by Nairametrics put them at ₦5.68 trillion, or 64.83% of all fund assets, as at April 2026. For a saver in Lagos the attraction is simple. For a Nigerian living in Houston or Atlanta who files a US return, the same fund raises a US tax question that most Nigerian fund managers never mention.
The IRS Instructions for Form 8621 (revised December 2025) define a passive foreign investment company by two tests, and a foreign corporation that meets either one is a PFIC:
- Income test: 75% or more of its gross income for the year is passive income.
- Asset test: at least 50% of its average assets produce passive income or are held to produce it.
Interest is passive income, and a money market fund's assets are interest-bearing paper, so a fund of this kind would normally meet both tests. The open question for some funds is classification: Nigerian collective schemes are often unit trusts, and whether a given scheme is treated as a foreign corporation for US purposes depends on how it is set up. Funds of this kind are commonly treated as PFICs, but confirm the classification of your fund with a US preparer who knows foreign funds. Our wider guide to Nigerian mutual funds and PFIC rules covers equity and bond funds too.
What the PFIC rules do to your money
If you make no election, the fund is a "section 1291 fund" and the default rules apply. The Form 8621 instructions describe the core of it:
- An excess distribution is the part of a year's distributions that is more than 125% of the average distributions you received from that fund over the previous three years (or your shorter holding period). Nothing received in your first year of holding counts as an excess distribution.
- The excess is spread back over the days you held the units. The share allocated to the current year and to years before the fund was a PFIC is taxed as ordinary income.
- The share allocated to earlier PFIC years carries a separate tax plus an interest charge under section 1291(c).
- Recognising a gain when you redeem units is also a Form 8621 filing event, and under section 1291 that gain goes through the same allocation and interest method rather than being taxed as an ordinary long-term capital gain.
Two elections can replace the default. A QEF election (section 1295) needs a PFIC Annual Information Statement from the fund showing your share of its ordinary earnings and net capital gain; ask your fund manager in writing whether it will produce one for US investors, because without it the election is not available. A mark-to-market election (section 1296) applies only to "marketable stock", meaning stock regularly traded on qualifying exchanges or certain stock described in the regulations; an unlisted Nigerian money market fund is unlikely to qualify, so check before relying on it. See our explainers on the QEF election and the Form 8621 filing itself.
The $25,000 exception and when Form 8621 is due
The instructions require a separate Form 8621 for each PFIC, attached to your income tax return and filed by its due date including extensions. If you do not have to file a return, the form goes on its own to the IRS Center in Ogden, Utah.
There is a relief for small holdings. You need not complete Part I (the annual information report) for a section 1291 fund if, on the last day of the tax year, the aggregate value of all your PFIC stock is $25,000 or less ($50,000 for a joint return), and you received no excess distribution and recognised no gain from that fund in the year. A separate $5,000 test applies to certain indirect holdings. The exception is tested on the year-end value of all PFIC stock you hold, not one fund at a time, and it falls away the year you redeem at a gain.
Worked example (illustrative figures)
A nurse in Dallas, filing single, puts ₦12,000,000 into a naira money market fund. Using an illustrative rate of ₦1,500 to $1, that is $8,000 at purchase. By 31 December, with interest reinvested, the holding is ₦13,800,000, which at an illustrative year-end rate of ₦1,520 is about $9,079. She holds no other PFIC, so the aggregate value is under $25,000. If she has no excess distribution and sells nothing, the Part I report is not required for that year. If in year three she redeems at a gain, Form 8621 is needed for that year whatever the value. The rates here are examples; the IRS says to convert at the rate prevailing when each amount is received or paid and that it has no official exchange rate.
The records to keep from the first deposit
PFIC calculations reach back to the day you bought. If you redeem years later and cannot show what you paid, the computation becomes guesswork. Keep, for each fund:
| Record | Why it matters |
|---|---|
| Each purchase: date, naira amount, units, unit price | Sets your holding period and cost for the section 1291 allocation |
| Naira-to-dollar rate used for each date, and its source | The IRS accepts any posted rate used consistently; you must be able to show which |
| Every distribution or dividend reinvestment, with dates | Needed for the 125% three-year average test |
| Year-end statement showing units and value | Tests the $25,000 / $50,000 exception and supports FBAR and Form 8938 values |
| Copies of every Form 8621 and any PFIC Annual Information Statement | The instructions say QEF shareholders must keep them; failing to produce them can end the election |
| Redemption confirmations | Show the gain recognised and the date |
FBAR and Form 8938 still apply
Form 8621 does not replace the other foreign-asset reports. The IRS FBAR page treats mutual fund holdings at a financial institution outside the US as foreign financial accounts, filed on FinCEN Form 114 if your foreign accounts together exceed $10,000 at any time in the year, due 15 April with an automatic extension to 15 October. Form 8938 has separate thresholds: for a single filer living in the US, more than $50,000 on the last day of the year or more than $75,000 at any time (IRS comparison page, reviewed September 2026). The Nigeria-side guide to money market funds explains how the funds themselves work.
Where Pryme fits
Pryme is a technology company, not a fund manager, and it does not sell money market funds. If what you need is naira on hand for family or a project at home, a Pryme account opened from the US can hold USD and NGN, and Swap shows the rate and the fee before you approve a conversion. Naira deposits are held by a licensed Nigerian microfinance bank, so treat the account as a foreign account for FBAR purposes. Statements you can download, including verifiable ones through VerifyDoc.ai (receipts and statements), help with the dated records the IRS expects. See multicurrency accounts.
Questions people ask
Is a Nigerian money market fund a PFIC?
Usually yes for a US taxpayer, because nearly all its income is interest and its assets produce passive income. The IRS tests are 75% passive income or 50% passive assets. Confirm the fund's US classification with a preparer.
Do I need Form 8621 if I only have a small amount in a naira fund?
Possibly not the Part I report: if all your PFIC stock is worth $25,000 or less at year-end ($50,000 joint) and you had no excess distribution or gain from that fund, the instructions say Part I need not be completed.
Can I make a QEF election on a Nigerian fund?
Only if the fund gives you a PFIC Annual Information Statement. Ask the manager in writing; without the statement the election is not available.
Does the FBAR cover my money market fund?
Yes, mutual fund accounts at institutions outside the US count toward the $10,000 FBAR threshold. Form 8938 may also apply depending on your total foreign assets.
