Withholding tax and quarterly returns in Ghana
How Ghanaian businesses withhold tax on payments to suppliers, file the monthly Form GH4 return and pre-pay corporate income tax through quarterly self-assessments on the GRA Taxpayers Portal.
Withholding tax (WHT) is one of the GRA's primary collection tools and applies to almost every B2B payment a Ghanaian business makes to suppliers, landlords, professionals and non-residents. Under the Income Tax Act 896 (2015), the payer is legally required to deduct WHT at source from gross payments, remit it to the GRA by the 15th of the following month using Form GH4, and issue a WHT certificate to the supplier so they can claim the credit on their own tax return. Rates vary: 5% on professional and management fees to residents, 7.5% on rent, 8% on management/technical service fees to companies, 10% on royalties, and 15% on dividends and most payments to non-residents. Alongside WHT, corporate income tax of 25% is pre-paid through quarterly self-assessments — Form CIT — submitted in March, June, September and December.
- WHT residents: 5% professional fees, 7.5% rent, 8% management/technical.
- WHT royalties: 10% on royalties and similar payments.
- WHT non-residents: 15% on dividends, interest, technical service fees.
- Form GH4: monthly WHT return, due by the 15th of the following month.
How it works
Classify the payment correctly. Each payment falls into a WHT category — professional fee, rent, royalty, management fee, dividend, interest, supply of goods, etc. — and each category has its own rate and rule. Mis-classification (e.g. treating a management fee as a generic supply) is a common audit finding because the WHT amount changes materially. The Certified Invoicing System usually flags the WHT line automatically based on a service code.
Deduct WHT at source from the gross invoice. If a professional invoices GHS 10,000 net + 15% VAT + 2.5% NHIL + 2.5% GETFL + 1% COVID Levy = GHS 12,100, the 5% WHT is computed on the net of GHS 10,000 = GHS 500. The payer transfers GHS 12,100 − GHS 500 = GHS 11,600 to the supplier and remits GHS 500 to the GRA. The VAT and levies are unaffected by WHT.
Issue a WHT certificate to the supplier showing the gross amount, the rate applied, the amount withheld and the GRA receipt reference. The supplier uses this certificate to claim a credit against their own corporate income tax at year-end. Without a certificate, the credit is disallowed and the supplier effectively pays the WHT twice.
File Form GH4 monthly by the 15th of the following month through the GRA Taxpayers Portal. The return aggregates all WHT deducted across suppliers, by category, and the payment is made by bank transfer or via the GRA mobile money/USSD shortcode. Late filing attracts a fixed penalty plus interest at the Bank of Ghana rate + 5%.
Pay corporate income tax in four quarterly instalments. Each company must lodge a self-assessment Form CIT estimating its annual chargeable income and pay one-quarter of the estimated CIT (currently 25% for most sectors) by 31 March, 30 June, 30 September and 31 December. The final return is reconciled in the next year and any over- or under-payment is settled. WHT certificates received from customers are netted against this liability.

Frequently asked questions
What WHT rate applies to a foreign software subscription?
A foreign SaaS or software subscription is typically treated as a royalty or technical service fee to a non-resident, attracting 10–15% WHT depending on classification and any double-taxation treaty between Ghana and the supplier's country. Treaties with the UK, Germany, France, South Africa and others often reduce the rate to 7.5% or 10%. The payer must apply the treaty rate at source — not refund later — and keep the supplier's tax residency certificate on file.
Is WHT deducted on the gross or on the net before VAT?
On the gross VAT-exclusive value (the net), not on the post-VAT total. For an invoice of GHS 10,000 net + 15% VAT + levies, the 5% professional WHT is GHS 500, computed on the GHS 10,000 net only. This is critical because applying the rate to the VAT-inclusive total would over-withhold by 15%+ and cause cash-flow issues for the supplier — and a successful supplier dispute would force the payer to pay the difference out of pocket.
What happens if I forget to deduct WHT?
Under the Income Tax Act 896, the payer becomes personally liable for the un-deducted WHT, plus a penalty of 3% per month and interest at the Bank of Ghana rate + 5%. The amount cannot be recovered from the supplier after the fact unless the contract explicitly allows it. Repeated failures lead to GRA assessments covering the prior three years and can be referred to the EOCO for criminal investigation if there is a pattern of intent.
How do quarterly self-assessments interact with WHT credits?
The quarterly Form CIT is an estimate of annual CIT liability divided by four. Each instalment is paid in cash, and at year-end the company files a final CIT return where it nets: (a) CIT due on chargeable income, less (b) the four quarterly instalments paid, less (c) all WHT certificates received from customers during the year. A net refund is rare; a top-up payment is more common. Carrying forward unused WHT credits is allowed for one year.
Are payments to other Ghanaian VAT-registered suppliers always subject to WHT?
Almost always for the categories listed — professional fees, rent, management/technical services, royalties — even if the supplier is VAT-registered and issues an E-VAT invoice. WHT and VAT are independent mechanisms: VAT is collected by the supplier and remitted by the supplier; WHT is deducted by the buyer and remitted by the buyer. The only exemptions are payments below specific de-minimis thresholds in some categories, payments to other GRA-recognised withholding agents, and payments to fully exempt bodies.
