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
Pick one fixed month, ideally before the UK tax year ends on 5 April, and work through the same list every year: UK allowances such as the £20,000 ISA limit for 2026 to 2027, foreign income you must report to HMRC, your Nigerian pension and property records, how much of your wealth is in naira, and whether your will and nominations still match your family. The value is in doing it on schedule, not in any single decision.
Why a fixed annual review helps
Money split between two countries drifts. A T-bill rolls over without anyone checking the rate, a relative stops sending the rent receipts, an RSA statement goes to an old email address, and the share of your savings held in naira grows or shrinks with the exchange rate rather than by choice. A yearly review is a way to notice drift before it becomes a problem. Treat it as a meeting with yourself, with a written list and a folder of last year's notes.
Many people choose January to March, because UK Self Assessment for the previous tax year has just been filed and the current tax year closes on 5 April, which GOV.UK uses as the boundary for allowances such as ISAs and Inheritance Tax gift exemptions.
The UK side
- ISA allowance. GOV.UK sets the allowance for 2026 to 2027 at £20,000 across cash, stocks and shares, innovative finance and Lifetime ISAs. You must be UK resident to pay in. Unused allowance does not carry over, so decide before 5 April. For how this compares with naira products, see UK ISA allowance versus Nigerian investments.
- Foreign income. GOV.UK says UK residents normally pay UK tax on foreign income such as overseas rent, interest and dividends, usually reported through Self Assessment, and that relief may apply if the same income is taxed in both countries. List every Nigerian income line for the year with its date and naira amount.
- Pensions. Check workplace pension contributions, any old pots from previous jobs and your State Pension record.
- Will and Inheritance Tax. GOV.UK's threshold is £325,000, with 40% charged above it, subject to exemptions. If you have built up assets in Nigeria, a UK will that ignores them may leave your family with a long process in Nigeria.
The Nigerian side
- RSA. Get the latest statement from your Pension Fund Administrator and confirm your next of kin and contact details. PenCom told ThisDay in January 2024 that accounts opened on or before 1 July 2019 need data recapture before benefits can be paid. See RSA data recapture from the UK.
- Fixed income. Note every T-bill, bond or fixed deposit with its maturity date and whether it rolls over automatically.
- Property. Confirm where the original title documents are kept, that land use charge or ground rent is paid, and that any tenant's rent has reached you in full. If rent is involved, UK tax on Lagos rental income sets out the reporting.
- Accounts and BVN. Make sure every Nigerian account is active, linked to your BVN and NIN, and reachable from the UK without a Nigerian SIM if possible.
- People. Write down who in Nigeria holds a power of attorney or handles money for you, and whether that still makes sense.
Your currency mix
Work out what share of your total wealth is held in naira. The figure moves with the exchange rate even if you do nothing, so record it using the same source each year; the Bank of England publishes daily spot rates against sterling. Then decide whether the share is deliberate. Naira assets may suit money meant for family or property at home; money for a UK house deposit or retirement in the UK carries currency risk if held in naira. FX risk on naira investments covers this in more depth.
Example: a one-page snapshot
| Item (example figures) | Currency | Value in £ |
|---|---|---|
| Stocks and shares ISA | GBP | £18,000 |
| Workplace pension | GBP | £22,000 |
| Lagos flat (estimate) | NGN | £40,000 |
| T-bills and savings | NGN | £6,000 |
| RSA balance | NGN | £4,000 |
| Total | £90,000 |
In this example, naira assets come to £50,000 of £90,000, or about 56%. Valuing a Lagos flat in pounds is rough, so note how you estimated it. Next year, compare the share and ask whether it changed because of decisions or because of the exchange rate.
The paperwork folder
- A list of every account and asset in both countries, with institution, account number ending and contact.
- Copies of title documents and receipts for property.
- Pension statements from both countries.
- Your will, any Nigerian will, and who holds the originals.
- Notes of what you decided this year and why.
Tell one trusted person where the folder is. A will must meet the rules where it is made; GOV.UK sets out what makes a will valid in England and Wales, including two adult witnesses who do not benefit.
Where Pryme fits
Seeing pounds and naira in one place makes the currency check quicker. A Pryme account holds GBP and NGN side by side, Savings Boxes keep naira savings for home in labelled pots, and the Personal Assistant can remind you of the review date and maturities; nothing moves without your approval.
Questions people ask
When should I do a yearly money review if I live in the UK?
Many people pick January to March, after Self Assessment and before the tax year ends on 5 April, when unused ISA allowance is lost.
Do I have to tell HMRC about income in Nigeria?
GOV.UK says UK residents normally pay UK tax on foreign income such as rent and interest, usually via Self Assessment, with relief possible if taxed twice.
How much of my savings should be in naira?
There is no right figure. Measure the share each year using the same exchange-rate source, and match it to what the money is for.
What documents should I keep for assets in Nigeria?
Title documents, receipts, RSA statements, account details and your will, with one trusted person knowing where they are.
