Who this guide is for

This guide is for buyers, sellers, tenants and developers who need to budget for and pay stamp duty in Kenya, and for anyone testing whether an exemption applies. It sits alongside our guides to real estate and property law, buying land and title transfer, and commercial leases in Kenya.

Historical context of stamp duty in Kenya

Stamp duty in Kenya has its origins in the British colonial administration, which introduced a version of the English Stamp Act to the East Africa Protectorate in the early twentieth century. The tax was designed as a documentary duty — it applied to instruments evidencing legal transactions rather than to the transactions themselves, and was collected by affixing a government stamp to the relevant document. The current Stamp Duty Act (Chapter 480 of the Laws of Kenya) is a direct successor to that colonial legislation, though it has been amended on numerous occasions since independence to adjust rates, extend exemptions and widen the range of instruments subject to the duty.

The administration of stamp duty has evolved significantly since the introduction of the Kenya Revenue Authority’s iTax system, which brought assessment and payment online for most categories of instruments. Before this digitalisation, parties to a property transaction were required to attend the Stamp Duty Office in person to have documents assessed and stamped — a process that could take several days and was a notorious source of delays in the conveyancing process. The online system has considerably reduced processing times, though the valuation step — in which the Commissioner of Lands must approve the assessed open-market value of a property before duty can be calculated — remains a potential bottleneck on transactions in areas where KRA and county government valuations diverge.

Background: what stamp duty is

Stamp duty is a tax on documents rather than on people. Under the Stamp Duty Act (Cap 480), certain instruments — most importantly transfers, charges and leases of property — must be “stamped”, meaning the tax must be paid, before they can be registered or relied on in any legal proceeding. The duty is administered by the Collector of Stamp Duty and collected by the Kenya Revenue Authority (KRA). Because an unstamped transfer cannot be registered at the Land Registry, stamp duty is not optional and it is a cost the buyer must plan for from the outset.

How stamp duty differs from other property taxes

Stamp duty is a transaction tax, payable once on the instrument that effects the transfer. It is distinct from land rates (an annual charge by the county government on land value), land rent (payable to the national government on leasehold land), and capital gains tax (payable by the seller on any gain realised on disposal). All four can apply on the same transaction, so buyers and sellers should budget for each separately.

The legal framework

The principal statute is the Stamp Duty Act (Cap 480), originally enacted in 1958 and amended several times since, most recently through successive Finance Acts. The Act sets out the instruments that are dutiable, the rates of duty, the exemptions and reliefs, and the penalties for non-compliance. It is supplemented by the Stamp Duty Regulations.

The Act operates alongside the Land Registration Act 2012 and the Land Act 2012, which together govern how land transactions are registered. In practice, the Registrar will not register a transfer, charge or lease unless the instrument has been stamped, creating a hard link between stamp duty compliance and the ability to complete a transaction.

The rates on a transfer

The standard rates

For a transfer of immovable property, the rate depends on where the property is located:

Instrument	Rate
Transfer of land in a city, municipality or gazetted town	4% of the value
Transfer of land outside a city, municipality or gazetted town	2% of the value
Lease (shorter term)	1% of the annual rent
Lease (longer term)	2% of the annual rent
Transfer of shares (marketable securities)	1% of the value
Nominal instruments (e.g. a power of attorney)	Small fixed duty (KES 200)

How the value is determined

Importantly, the duty is charged on the higher of the purchase price stated in the transfer and the value assessed by a government valuer from the Ministry of Lands. The valuer inspects the property and reports the current market value, and the Collector of Stamp Duty assesses the duty on that basis. This means that agreeing a low price on paper does not cut the duty — the government valuation sets the floor. If the buyer disagrees with the valuation, the Act provides for a reference to the Lands Tribunal, but in practice most buyers accept the valuation and pay rather than delay the transaction.

How stamp duty is assessed and paid

The Ardhisasa platform

Since 2024, all stamp duty applications in Kenya are processed through the Ardhisasa digital platform (ardhisasa.lands.go.ke), which integrates with the KRA’s iTax system for payment. The platform replaced the earlier manual process and is now the only route for stamp duty assessment and payment on property transfers.

The steps

The sequence runs as follows:

1. Initiate the application. The buyer’s advocate lodges the transfer instrument and supporting documents (title deed, sale agreement, KRA PINs of buyer and seller) on the Ardhisasa platform.
2. Government valuation. A government valuer from the Ministry of Lands assesses the market value of the property. This is the figure the Collector uses to compute the duty.
3. Assessment notice. The Collector of Stamp Duty issues an assessment notice showing the duty payable.
4. Payment. The buyer pays the assessed duty through KRA’s iTax platform (Payments → Payment Registration → Stamp Duty). Payment is made via bank transfer or mobile money using the generated payment slip.
5. Stamping. Once payment is confirmed, the instrument is stamped — electronically marked as duty-paid — and can then be lodged for registration at the Land Registry.

The payment window

For instruments executed within Kenya, the duty must be paid within 30 days of the date of assessment. For documents executed abroad, the period is 30 days from the date the documents are received in Kenya. Missing this window triggers penalties, so treat the assessment as a deadline, not a formality.

Stamp duty on a lease

A lease is dutiable too. The duty is charged by reference to the annual rent and the length of the term. Broadly, it is one per cent of the average annual rent for a shorter lease and two per cent for a longer one. Tenants taking commercial or industrial space often overlook this until registration, at which point they face a delay they had not budgeted for. Build the duty into the deal from the start, and factor it into your total occupancy cost. We flag this in our guide to commercial lease agreements in Kenya.

Lease renewals and surrenders

A renewal of a lease is a fresh instrument and attracts stamp duty in its own right. A surrender of a lease, however, may qualify for relief, depending on the circumstances. If you are negotiating a lease surrender and renewal as a single transaction, check whether relief applies before committing.

Stamp duty on other instruments

Stamp duty is not limited to property transactions. The Act covers a broad range of instruments, including:

• Share transfers. A transfer of shares (marketable securities) attracts duty at one per cent of the consideration or market value.
• Mortgages and charges. The creation of a charge over property attracts a fixed duty.
• Powers of attorney. A general power of attorney and certain other legal instruments attract a nominal fixed duty.
• Insurance policies. Certain insurance instruments are dutiable at rates set out in the Act’s schedule.
• Receipts and bills of exchange. Historically dutiable, though the practical significance has diminished for most businesses.

For property transactions, the transfer and the lease are the instruments that matter most. But if a transaction involves a share sale (for example, buying a company that owns land rather than buying the land directly), the one per cent duty on shares rather than the four per cent duty on a transfer can be a significant planning point.

The exemptions

How to apply for a stamp duty exemption

Where a transaction is eligible for one of the statutory exemptions under the Stamp Duty Act, the exemption is not applied automatically: the applicant must make a formal application to the Commissioner of Stamp Duty (an officer of the Kenya Revenue Authority) and obtain written confirmation before the instrument is presented for stamping. The application should identify the relevant exemption provision by section number, describe the nature of the transaction, provide supporting documentation (for example, certified copies of the company resolution and certificate of incorporation for an intra-group transfer, or the instrument constituting the trust for a transfer to a family trust), and include the draft instrument to be stamped. KRA requires that the application be made before the instrument is executed, or at the latest before it is presented for stamping, since a duty assessed and paid cannot ordinarily be refunded after the fact. Where there is any uncertainty about whether a particular transaction qualifies for an exemption, an advance ruling from the Commissioner reduces the risk of a later assessment and penalty.

The Act and subsidiary legislation provide a number of reliefs. In practice the most useful are:

• First-time home buyer under the Affordable Housing Scheme. A first-time buyer acquiring a home under the government’s affordable housing programme can qualify for stamp duty relief, subject to conditions on the value of the property and the buyer’s status.
• Transfers within a family. Transfers of family property — including to a company wholly owned by the family or to a registered family trust — can be exempt from stamp duty. The family relationship and the nature of the transfer must satisfy the Collector.
• Spousal transfers. Transfers of property between spouses are exempt.
• Transfers between associated companies. A transfer within a corporate group, where one company holds at least ninety per cent of the other or both are held by a common parent, can be exempt on conditions.
• Charitable and educational institutions. Instruments in favour of registered charitable or educational bodies can qualify for relief.
• Special Economic Zone enterprises. Instruments relating to Special Economic Zone enterprises may attract relief under the Special Economic Zones Act.
• Security-related instruments. The discharge of a charge, and some lease surrenders, attract relief or reduced duty.

Two points matter. First, an exemption is not automatic — you must apply to the Collector of Stamp Duty with supporting documents (for example, a statutory declaration, marriage certificate, or certificate of incorporation showing the family or group relationship). Second, the conditions are technical, so confirm eligibility before you rely on it in your transaction budget.

Penalties for late stamping

The consequences of failing to stamp an instrument on time are serious:

• Financial penalty. A penalty of five per cent of the assessed duty is charged for every quarter (three-month period) from the date of the instrument until the duty is paid. On a large transaction, this compounds quickly.
• The instrument is inadmissible. An unstamped or insufficiently stamped instrument cannot be admitted as evidence in any court or legal proceeding. This means you cannot enforce the rights the instrument creates — the transfer, the lease, the charge — until you pay the duty and the penalty.
• Registration is blocked. The Land Registrar will not register an unstamped instrument, so the buyer does not acquire legal title until the duty is paid.

In short, failing to pay stamp duty does not save money — it costs more (through penalties) and creates legal risk (through unenforceability). Pay within the 30-day window.

Recent changes

Expansion of urban zones (2024)

In April 2024, the Council of Governors gazetted additional urban areas and municipalities across multiple counties. Properties in those areas — including parts of Kiambu, Kajiado and Machakos counties that border Nairobi — now attract the four per cent urban rate rather than the two per cent rural rate. Buyers of property in peri-urban areas should check whether their location has been reclassified before budgeting at the lower rate.

Ardhisasa digital platform

The migration to the Ardhisasa platform has streamlined the stamp duty assessment process but also made it harder to complete a transaction outside the system. All applications, valuations and payments are now tracked digitally, and there is no manual workaround. Advocates and buyers should be comfortable navigating the platform, or engage a firm that is.

Closing costs: the full picture

Stamp duty is the largest single closing cost for most buyers, but it is not the only one. On a typical KES 10 million urban property purchase, the costs break down approximately as follows:

Cost item	Approximate amount
Stamp duty (4%)	KES 400,000
Legal fees (~1.5% of value)	KES 150,000
VAT on legal fees (16%)	KES 24,000
Government valuation fee	KES 10,000 – 50,000
Land search and registration	KES 5,000 – 10,000

The total comes to roughly six to eight per cent of the purchase price on top of the price itself. Budget for it early — too many transactions stall because the buyer did not have the closing costs ready.

Common questions

How much is stamp duty in Kenya? Four per cent of the value for property in a city, municipality or gazetted town, and two per cent elsewhere.

Is duty charged on the price or the valuation? On the higher of the two. A government valuer assesses the market value, and that figure sets the floor.

Who pays stamp duty in Kenya? The buyer pays stamp duty on a transfer. On a lease, it is typically the tenant, though the parties can agree otherwise.

Is stamp duty payable on a lease? Yes, by reference to the annual rent and the term of the lease.

Can I avoid stamp duty by stating a low price? No. The government valuation governs, so a low stated price does not reduce the duty.

Are the exemptions automatic? No. You must apply to the Collector of Stamp Duty with supporting documents and meet the statutory conditions.

What happens if I do not pay stamp duty? The instrument cannot be registered, it is inadmissible in court, and a penalty of five per cent per quarter accrues from the date of the instrument.

How long do I have to pay? Thirty days from the date of assessment for instruments executed in Kenya.

Common pitfalls

The usual errors are: budgeting for the purchase price alone without accounting for the four per cent stamp duty; assuming a low stated price will reduce the duty when the government valuation governs; missing the 30-day payment window and incurring penalty at five per cent per quarter; assuming a family or first-time-buyer exemption applies without making the formal application; buying property in a recently gazetted urban area and budgeting at the two per cent rural rate when the four per cent urban rate now applies; and forgetting that a lease, not just a purchase, is dutiable.

What you should do now

• Budget for stamp duty — four per cent or two per cent of the value — on top of the purchase price, before you commit to the transaction.
• Expect the duty to be based on the government valuation, not just your agreed price.
• Check whether your property falls in a recently gazetted urban area that now attracts the four per cent rate.
• If you think an exemption applies, confirm the conditions and apply to the Collector in good time — do not assume it is automatic.
• For a lease, factor the duty on the annual rent into your occupancy budget.
• Pay within the 30-day assessment window to avoid penalties and registration delay.
• Budget for the full closing costs (stamp duty, legal fees, VAT, valuation and registration fees) — typically six to eight per cent of the purchase price.
