What Is Stamp Duty?
Stamp duty is a government tax levied on the transfer of property ownership in Kenya. It is governed by the Stamp Duty Act (Cap 480) and collected by the Kenya Revenue Authority. When land or a building changes hands — whether through a sale, a gift, or an inheritance — stamp duty must be paid before the transfer can be registered at the Land Registry.
Think of it as the government's fee for officially recognising that the property now belongs to you. Without paying it, you cannot register the transfer, and without registration, you do not legally own the property regardless of what the sale agreement says.
What Are the Stamp Duty Rates in Kenya?
The rates depend on where the property is located and what type of asset is being transferred.
- Urban areas (municipalities and cities): 4% of the property value
- Rural areas: 2% of the property value
- Transfer of shares or securities: 1% of the value
- Lease agreements: Graduated scale based on the length of the lease term
For most Kenyans buying residential property, the relevant rate is either 4% (for properties in Nairobi, Mombasa, Kisumu, and other gazetted urban areas) or 2% (for land or houses in rural counties). If you are buying a plot in Kiambu town, that is urban — 4%. A farm in Meru County — 2%.
Who Pays Stamp Duty?
The buyer — referred to in law as the transferee — is legally responsible for paying stamp duty. This is non-negotiable. The seller does not pay it. The bank does not pay it on your behalf (though they will require confirmation that it has been paid before releasing the title deed). It comes out of your pocket as the person acquiring the property.
Some sale agreements attempt to share this cost between buyer and seller, but that is a commercial arrangement between the parties — the KRA's obligation falls entirely on the buyer regardless of what the contract says.
When Is It Due?
Stamp duty must be paid to KRA before or at the time of registering the transfer at the Land Registry. In practice, your conveyancing lawyer handles this as part of the completion process. Once the sale is agreed and the funds are ready, the lawyer generates a stamp duty assessment through the KRA iTax portal, you pay the assessed amount, and the paid receipt is then presented at the Lands Registry to process the transfer of title into your name.
Delaying payment attracts a penalty — 5% of the unpaid duty per month — so there is no benefit in dragging your feet once the purchase is proceeding.

Mortgage Calculator →How Is Stamp Duty Calculated?
The calculation seems simple: multiply the property value by the applicable rate. The complication is in what counts as "the property value."
KRA uses the higher of two figures: the actual purchase price stated in the sale agreement, or the government valuation carried out by the Commissioner of Lands (also called the Stamp Duty Valuation).
This distinction matters and has caught many buyers off guard.
The Government Valuation Trap
When you buy a property, KRA will commission or reference a valuation of the property independently of what you agreed to pay. If the government's valuation comes in higher than your agreed purchase price, stamp duty is calculated on the government's figure — not yours.
This happens more often than buyers expect. Government valuations can lag the market on the way up, but they can also be surprisingly high in areas the Lands ministry considers prime or undervalued. If you negotiated a seller down from KES 7M to KES 5.5M, do not assume your stamp duty will be based on KES 5.5M — the valuation may push it back toward the KES 7M original asking price.
If the government valuation comes in higher than your purchase price and you believe it is wrong, you have the right to appeal through KRA. Your advocate can guide you through this process, but it takes time and is not guaranteed to succeed.
Worked Examples
Example 1: KES 6,000,000 apartment in Nairobi (urban)
Stamp duty rate: 4%
Stamp duty payable: 4% × KES 6,000,000 = KES 240,000
Example 2: KES 2,000,000 plot in a rural area
Stamp duty rate: 2%
Stamp duty payable: 2% × KES 2,000,000 = KES 40,000
Example 3: The government valuation is higher than the purchase price
Purchase price: KES 5,500,000 (urban property)
Government valuation: KES 6,800,000
Stamp duty payable: 4% × KES 6,800,000 = KES 272,000 (not KES 220,000)
The buyer pays an extra KES 52,000 in stamp duty because the government's figure is used.
How to Pay Stamp Duty in Kenya
Payment is processed through the KRA iTax platform. The steps are:
- Your conveyancing lawyer submits the property details to KRA via iTax for assessment.
- KRA issues a stamp duty assessment — this confirms the amount due based on their valuation.
- You generate a payment slip (E-slip) from the iTax portal.
- Pay the amount at a KRA-approved bank or via M-Pesa using the Paybill number provided on the E-slip.
- KRA stamps the transfer documents confirming payment.
- Your lawyer presents the stamped documents at the Land Registry to effect the transfer.
Your lawyer will typically manage steps 1 through 5 on your behalf. What you need to ensure is that the money is available and ready when the process reaches that stage — stamp duty cannot be paid in instalments and cannot be deferred without penalty.
Exemptions and Reliefs
Not every property transfer attracts stamp duty at full rates. The main exemptions include:
Affordable housing first-time buyer exemption (0%)
Kenya's affordable housing programme has included a stamp duty waiver for first-time homebuyers acquiring units under the programme. In theory, qualifying buyers pay 0% stamp duty. In practice, the implementation has been inconsistent — some buyers have received the waiver smoothly, others have faced delays or been told they do not qualify despite meeting the stated criteria.
To check whether you qualify, you need to confirm through the State Department of Housing whether the specific development you are purchasing from is registered under the affordable housing programme, and whether the waiver is currently being processed for that scheme. Your lawyer should be able to advise based on current KRA guidance at the time of your purchase.
Transfers between spouses (0%)
Property transferred between spouses — including as a gift — is exempt from stamp duty under the Stamp Duty Act. This applies to transfers where the property moves from one spouse to the other, not to transfers to children or other family members.
Government and public institutions
Central government, county governments, and certain gazetted public institutions are exempt from stamp duty when acquiring property for public purposes.
The Full Picture: All Transaction Costs on a KES 6M Property
Stamp duty is the largest single transaction cost but it is not the only one. Below is a realistic breakdown of everything a buyer should budget for when purchasing a KES 6 million property in an urban area.
| Cost item | Basis | Estimated amount |
|---|---|---|
| Stamp duty | 4% of property value (urban) | KES 240,000 |
| Legal / advocate fees | ~1–1.5% of property value (LSK scale) | KES 75,000–90,000 |
| Bank valuation fee | Flat fee charged by valuer | KES 10,000–20,000 |
| Land Registry registration fee | Government fee for registering transfer | KES 1,000–5,000 |
| Official search (Lands Registry) | Title verification search | KES 500–2,000 |
| Land search (county / Ardhi House) | Confirm no encumbrances | KES 500–2,000 |
| Survey fees (for plots) | If plot boundaries need to be surveyed | KES 20,000–80,000 |
| NEMA certificate | Environmental compliance (some properties) | Varies — may not apply |
| Total additional costs | (excluding deposit and survey) | ~KES 330,000–360,000 |
These costs come on top of your deposit and the purchase price itself. On a KES 6M property with a 10% deposit of KES 600,000, you should realistically budget for KES 930,000 to KES 960,000 in total upfront cash before you get the keys — and that is before any moving or furnishing costs.
Many buyers plan carefully for the deposit but do not factor transaction costs into their savings target. The result is that they reach the completion stage and scramble to find an extra KES 300,000–360,000 at short notice, sometimes delaying the transfer or needing to borrow at short notice.
Legal Fees: What the Law Society of Kenya Scale Looks Like
Conveyancing fees in Kenya are guided by the Advocates Remuneration Order, which sets a scale based on the value of the transaction. For a KES 6M property, the indicative scale fee is approximately KES 75,000 to KES 90,000 for the buyer's advocate. Some lawyers charge flat fees or negotiate below scale for straightforward transactions; others charge above scale for complex deals. Always agree the fee upfront before engagement.
Note that the seller also pays their own advocate — that is the seller's cost, not yours. But if you are financing through a bank, the bank may require you to pay their legal costs as well, which can add another KES 20,000–40,000. Ask your bank explicitly what legal costs are included in their loan origination fees versus what you will pay separately.

Mortgage Calculator →Stamp Duty on Rural Property: Is It Really Just 2%?
Yes — but the classification matters. "Rural" for stamp duty purposes means land outside a gazetted municipality or city boundary. This includes many peri-urban areas that buyers assume are urban: parts of Thika, Ngong, Ongata Rongai, and areas within county boundaries but outside the specific gazetted town limits.
If you are buying land on the outskirts of a town and are not sure whether it falls inside or outside the urban classification, your lawyer should verify this before completion. The difference between 2% and 4% on a KES 5M property is KES 100,000.
What Happens If You Undervalue the Property?
Some buyers and sellers agree to state a lower purchase price in the sale agreement than what was actually paid, hoping to reduce the stamp duty calculation. This is tax fraud. KRA's independent valuation process exists precisely to catch this, and where the government's valuation exceeds the stated price significantly, it can trigger further scrutiny. The penalties for stamp duty fraud include payment of the full amount due plus interest, and potentially criminal liability.
It is not worth it. The stamp duty on most residential transactions is a predictable, known cost — build it into your budget honestly.
How to Budget for a Property Purchase in Kenya
The practical advice is straightforward: when you set your property budget, the purchase price is not your total outlay. Use this rule of thumb for urban property:
- Add 4% of the purchase price for stamp duty.
- Add 1.5% for legal fees.
- Add KES 30,000–50,000 for valuations, searches, and registration.
- Your total cash required = deposit + stamp duty + legal fees + other costs.
On a KES 6M property with a 10% deposit: that is KES 600,000 (deposit) + KES 240,000 (stamp duty) + KES 90,000 (legal) + KES 30,000 (other) = KES 960,000 in upfront cash, before the mortgage payments begin.
If you are also buying a plot for future construction, add survey fees of KES 20,000–80,000 depending on the size and location of the land.
The Bottom Line
Stamp duty is not a surprise you can negotiate away or defer. It is a statutory obligation that falls on you as the buyer, it must be paid before your title is registered, and it is calculated on the higher of what you paid or what the government thinks the property is worth.
At 4% for urban property, it is the single largest transaction cost in most residential purchases — bigger than legal fees, valuation, registration, and searches combined. On a KES 6M property, it is KES 240,000. On a KES 10M property, it is KES 400,000.
Plan for it from the beginning. Save for it before you start viewing properties seriously. And when you find a property you want to buy, ask your lawyer for a full completion statement covering every cost before you commit. There should be no surprises at the signing table.
