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
Agree a written contract for a defined piece of work, get a proper invoice from the Nigerian contractor, pay against it and keep the invoice, contract and bank advice together. On the Ghana side, PwC lists a 20% final withholding tax on payments to non-residents for goods, works or services, so check with GRA or an adviser whether a given payment is caught before you pay, and do not treat someone who works like an employee as a contractor.
Paying a designer in Lagos, a developer in Abuja or a sales agent in Port Harcourt from a Ghana business is common and usually simple at the bank. The parts that go wrong are classification, tax and paperwork. This guide takes them in that order.
Contractor or employee?
Start here, because everything else depends on it. A contractor runs their own business: they set their hours, use their own equipment, can work for others, invoice for results and carry their own risk. Someone who works fixed hours under your direction, only for you, on a monthly fee that looks like a salary is behaving like an employee, whatever the contract calls them. If that is the arrangement, read paying Nigeria-based staff from a Ghana company instead.
- Pay for deliverables or for time billed on an invoice, not a fixed monthly 'salary'.
- Let the contractor control how the work is done.
- Avoid company email titles, staff handbooks and leave allowances for contractors.
- Review the arrangement once a year; long, exclusive contracts drift towards employment.
The Ghana tax question: withholding on non-residents
Ghana's withholding tax rules are the part most Ghana businesses miss. PwC's Ghana summary, reviewed in March 2026, lists these rates on payments to non-resident persons, all as final taxes:
| Payment to a non-resident | Ghana WHT (PwC, Mar 2026) |
|---|---|
| Management, consulting, technical service and endorsement fees | 20% |
| Goods, works or any services | 20% |
| Royalties, natural resource payments and rents | 15% |
| Dividends | 8% |
| Interest | 8% |
Whether a particular payment to a Nigerian contractor is caught depends on Ghana's source rules: for example, whether the service is treated as provided in Ghana. That is a judgement for GRA or a Ghanaian tax adviser, and this article does not make it for you. What matters practically is that you decide before paying, because if tax should have been withheld, the payer is usually the one asked for it. Our guide to Ghana WHT on payments to Nigerian contractors goes further. There is no Ghana-Nigeria double tax treaty in force to reduce the rate; PwC's Ghana treaty table does not list Nigeria.
VAT is a separate point. PwC notes that VAT on imported services is payable by the importer, so a VAT-registered Ghana business buying services from a Nigerian contractor should check whether it must account for Ghana VAT on that purchase.
The Nigerian side
The contractor is taxed in Nigeria on their own income, and that is their responsibility, not yours. Nigerian withholding tax is a deduction made by the payer, and the sources we checked describe it for payers in Nigeria; we found nothing that makes a Ghana company paying from abroad a Nigerian withholding agent. If you pay through a Nigerian entity, that entity may have to deduct, so check before routing payments that way. Our Nigeria library covers paying Nigerian contractors from abroad from the contractor's side.
What the invoice and records should show
- A signed contract or statement of work with scope, price, currency and payment terms.
- An invoice with the contractor's full name or business name, address, invoice number, date, description of work, amount and currency.
- Where you withhold Ghana tax, the gross amount, the tax withheld and the net paid, and the GRA receipt for the tax.
- The bank or transfer advice showing the amount, date and the account it went to.
- Delivery evidence: the files, report or sign-off showing the work was done.
PwC's Ghana tax administration summary says records must be kept for at least six years under the Revenue Administration Act, 2016 (Act 915). For a fuller list, see records for cross-border payments from Ghana.
A worked example
Example only: a Ghana agency owes a Lagos developer GH¢10,000 for a website. If its adviser concludes the 20% non-resident rate applies, the agency withholds GH¢2,000, pays GH¢8,000 to the developer and pays GH¢2,000 to GRA. If the adviser concludes no Ghana WHT applies, the developer gets the full GH¢10,000. The contract should say which party bears any tax, so the developer is not surprised.
Where Pryme fits
A Pryme Business Account can pay a Nigerian contractor in naira from funds you hold in dollars or other currencies, with Swap showing the rate and fee before you approve. Bulk payouts handle several contractors at once, and each payment can carry a verifiable receipt.
Questions people ask
Do I deduct Nigerian withholding tax when paying a contractor from Ghana?
The sources we checked describe Nigerian WHT for payers in Nigeria, not for a Ghana company paying from abroad. The contractor declares the income in Nigeria. If you pay through a Nigerian entity, that entity may have to deduct.
Is there Ghana withholding tax on payments to Nigerian contractors?
PwC lists 20% final WHT on payments to non-residents for goods, works or services. Whether a specific payment is caught depends on Ghana's source rules, so check with GRA or an adviser.
Does the Ghana-Nigeria tax treaty reduce the rate?
No treaty is in force. PwC's Ghana treaty table does not list Nigeria, and PwC's Nigeria page says the Ghana treaty was ratified only in Nigeria.
How long should I keep contractor records?
At least six years, under Ghana's Revenue Administration Act, as summarised by PwC.
