Withholding Tax in Kenya: What It Is, Who Deducts It, and How to Claim It Back

What Withholding Tax Actually Is

Withholding tax (WHT) is a collection mechanism, not a separate type of tax. Instead of waiting for you to file an annual return and pay your income tax in one lump sum, KRA requires certain payers to deduct a portion of specific payments at source and remit it directly to KRA on your behalf.

The key word is "pre-payment." For most resident recipients, WHT is not a final tax — it is an advance payment against the income tax you would otherwise owe at the end of the year. When you file your annual income tax return, you declare the full gross income and then claim credit for the WHT already deducted. If the credit is larger than your liability, you can claim a refund. If your total tax is larger than the credit, you pay the difference.

The system exists because it reduces the risk that tax goes uncollected. Compliance rates on annual returns are imperfect; withholding at source means KRA receives money the moment the transaction happens.

Who Must Deduct WHT

Not every payer in Kenya is obligated to withhold. The Income Tax Act specifies "prescribed persons" — entities legally required to deduct WHT when making qualifying payments. Prescribed persons include companies incorporated in Kenya, public bodies and government entities, banks and financial institutions, insurance companies, and any person specifically designated by the Commissioner.

An individual sole trader paying another individual is generally not a prescribed person and is not required to deduct WHT. So if you are a freelance designer and you subcontract work to another freelancer, you do not need to withhold on what you pay them. But if that same subcontractor invoices a company, the company must withhold.

If you are unsure whether you or your client qualifies as a prescribed person, the safest step is to confirm with a tax advisor before the invoice is issued — not after.

WHT Rates at a Glance

The rate depends on both the type of payment and whether the recipient is a Kenya tax resident or a non-resident. Non-residents generally face higher rates because they are less likely to file a Kenyan annual return.

Note on Double Taxation Agreements (DTAs): Kenya has tax treaties with several countries, including the UK, Germany, India, and others. Where a DTA applies, the treaty rate may be lower than the domestic non-resident rate. A non-resident recipient should check whether their home country has a DTA with Kenya before invoicing.

The Practical Mechanics: From Invoice to Credit

The best way to understand WHT is to walk through what happens on a real transaction.

Scenario: You are a management consultant — a Kenya tax resident — and you invoice a company KES 100,000 for advisory services. The company is a prescribed person.

The end result: the full KES 100,000 is taxed at your marginal income tax rate, but KES 5,000 of that tax has already been collected. You only pay the remainder when you file. If the WHT credit across all your clients for the year exceeds your total income tax liability, you are entitled to a refund from KRA.

The WHT Certificate — Why You Must Get It

The WHT certificate (sometimes called a P10A, or issued through KRA's iTax system) is the document that proves to KRA that tax was deducted on your income and remitted on your behalf. Without it, your WHT credit claim has no supporting evidence and can be disallowed during an audit.

Your client is legally required to issue this certificate after remitting the WHT to KRA. In practice, some clients are slow about it. Request the certificate at the time of payment — do not wait until tax season. Once issued, file it with your tax records alongside your invoices and bank statements.

If a client withholds tax from your payment but fails to remit it to KRA, they are in breach of their obligations. You still have the right to claim the credit — the failure to remit is their compliance problem. However, KRA may dispute your credit if there is no matching payment in their system, which makes recovering that certificate and following up with your client important even when things go wrong.

WHT vs VAT: Two Very Different Deductions

This is the most common point of confusion for people new to Kenya's tax system. VAT and WHT both appear on invoices, but they work in opposite directions.

VAT is added on top of your fee. If you are VAT-registered and you charge KES 100,000 for a service, you add 16% VAT: the invoice total is KES 116,000. Your client pays you KES 116,000. You collect the VAT and remit KES 16,000 to KRA yourself when you file your VAT return.

WHT is deducted from your fee. The client pays you less than the invoice amount and remits the difference to KRA on your behalf.

On the same invoice both can apply at once. A KES 100,000 professional fee invoice from a VAT-registered consultant to a prescribed-person company works like this:

• Invoice: KES 100,000 + KES 16,000 VAT = KES 116,000 total
• Client deducts 5% WHT on the fee (not on VAT): KES 5,000
• Client pays you: KES 111,000 (KES 116,000 minus KES 5,000 WHT)
• Client separately remits KES 16,000 VAT to KRA (via their own VAT return)
• Client separately remits KES 5,000 WHT to KRA
• You receive KES 111,000 and hold KES 16,000 of that to remit as your output VAT

Note that WHT applies to the fee, not to the VAT portion. A client who deducts 5% WHT from the full invoice amount including VAT is making an error.

Non-Residents: When WHT Is the Final Tax

The rules differ for non-residents. For certain payment types made to persons who are not Kenya tax residents — dividends, interest, royalties, management fees — WHT is treated as a final tax. The non-resident does not need to file a Kenyan income tax return; the WHT deducted by the payer fully discharges their Kenyan tax liability on that income.

For non-residents providing services in Kenya, the picture is more nuanced. Whether WHT is a final tax or a credit against a Kenyan return depends on whether the non-resident has a permanent establishment in Kenya — essentially, a fixed place of business here. If they do, they may need to file a Kenyan return. If they do not, the 20% WHT is typically the final tax on that income.

The applicable DTA, if any, can also override these domestic rules. Non-residents should take specific tax advice in both their home country and Kenya before providing services to Kenyan clients.

Common Mistakes That Create Problems

Not requesting the WHT certificate. You cannot claim a credit you cannot prove. Ask for the certificate promptly — waiting until March of the following year when you are filing your return is too late to chase a client who may have moved on.

Treating WHT as a final tax when it is not. A consultant who receives KES 95,000 net and thinks "tax already paid, nothing to file" is wrong. The KES 100,000 gross income still needs to appear on an annual income tax return. The WHT credit reduces what you owe but does not eliminate the filing obligation.

Failing to declare income because WHT was deducted. KRA's system cross-references WHT remittances from clients against taxpayer returns. If your client remits WHT against your PIN and you do not declare that income on your return, the mismatch will appear. Declare the gross amount; claim the credit.

Clients deducting WHT when they are not prescribed persons. If your client is an individual sole trader and not a company or registered entity, they may not have the legal obligation to deduct WHT. Clients who deduct WHT without authority and fail to remit it create a mess that can take time to resolve with KRA.

The Bottom Line

Withholding tax is not money lost. It is your income tax being collected earlier than you would otherwise pay it, by someone else on your behalf. The transaction is complete when you receive the WHT certificate, declare the gross income on your annual return, and claim the credit. Done correctly, you pay no more tax than you would have anyway — and in many cases, a year's worth of WHT credits across multiple clients produces a refund.

The practical discipline is straightforward: always issue a proper invoice showing the gross fee, always request the WHT certificate promptly after your client remits, and always declare the gross amount on your income tax return. The credit does the rest.
