What is stamp duty on property in Kenya?

A tax payable on the instrument of transfer, assessed on the value of the property and required before the transfer can be registered. The rates, thresholds and any exemptions are set by law and vary with the nature and location of the property, so the figure for your transaction is a question for your advocate.

Is stamp duty calculated on the purchase price?

It is assessed on the value of the property as determined for the purpose, which is not automatically the price agreed between the parties, and a government valuer may be involved. Budgeting from the agreed price alone is how buyers get surprised.

What happens if stamp duty is not paid?

The instrument cannot be registered, so the buyer's interest does not reach the register even though they have paid. Late stamping also attracts penalties. A buyer in occupation whose transfer was never registered is in a much weaker position than they usually realise.

What else should I budget for when buying property?

Beyond the price: stamp duty, legal fees and disbursements, search fees, survey and valuation, registration fees, any rates or land rent arrears being settled, and fit-out or repairs before the property can be occupied or let. Together these materially change what the asset actually cost you.

Stamp duty

Also called: duty · transfer duty · stamping · stamp duty on transfer

A tax payable on certain instruments, including a transfer of land, assessed on the value of the property and required before the instrument can be registered.

Stamp duty is a tax on the document rather than on the transaction. A transfer that has not been stamped generally cannot be registered, which means the buyer's interest does not reach the register, which means the thing they paid for is not yet theirs in the way they think it is.

It is also the single largest item people leave out of the cost of buying property.

The two things to understand

It is assessed on value, not on price. The assessment is made on the value of the property as determined for the purpose, and a government valuer may be involved. A price agreed between the parties is not automatically the figure duty is calculated on, and a buyer who budgets from the purchase price alone can be surprised.

It is a condition of registration. Until the instrument is stamped, it cannot be registered. This is the mechanism that makes duty unavoidable rather than optional.

Why it belongs in the acquisition cost

The all-in cost of buying is not the purchase price. It typically includes:

Purchase price.
Stamp duty on the transfer.
Legal fees and disbursements.
Search fees, survey and valuation.
Registration fees.
Any rates or rent arrears being settled. See land rates and land rent.
Fit-out or repairs before the property can be let or occupied.

A buyer calculating rental yield on purchase price alone is dividing by the wrong number, and the error runs in the flattering direction.

What this entry does not give you

Rates, thresholds, exemptions and timelines. Those are set by law, they differ by the nature of the property and its location, they change, and a confidently wrong percentage on a page like this would cost somebody real money.

Your advocate will tell you the figure for your transaction, and it is one of the first questions to ask them, because it affects what you can afford rather than merely what you pay at the end.

Timing

Duty is payable within a period set by law, and late stamping attracts penalties. Since registration depends on stamping, a delay here holds up the whole transfer.

The practical point for a buyer: ask when it falls due and make sure the money is available then, not at some undefined point after completion. A buyer who has spent everything on the purchase price and has nothing left for duty has a transfer that cannot be registered.

What goes wrong

It is not budgeted for. The commonest failure, and it is entirely avoidable by asking one question early.

The assessment exceeds expectations. Because it is based on value rather than on the agreed price.

Stamping is delayed. Penalties accrue and registration waits.

The transfer is never registered. A buyer in occupation, having paid in full, whose interest is not on the register, is in a much weaker position than they believe, and the weakness usually surfaces when they try to sell or to charge the property.
