The Foreign Buyer's Tax Guide to Kenyan Property in 2026

If you are buying property in Kenya as a non-resident, tax will take a bigger bite than it does for a local, and it lands at three points: when you buy, while you hold and rent, and when you sell. None of the rates are hidden, but the non-resident rental rate in particular can quietly wreck a yield calculation if you do not plan for it. Here is the full picture for 2026.

When you buy: stamp duty

Stamp duty is the main transaction tax, paid by the buyer before the transfer can be registered. The rate depends on location and use. It is 4% of market value for property in urban areas, 2% for property in rural areas, and 6% for commercial property. The valuation is done by a government valuer, so you cannot simply declare a low figure to reduce the bill.

On a KES 20 million urban apartment, that is KES 800,000 in stamp duty alone. Budget for it as a real, upfront cost, not a rounding error, and add legal fees and registration costs on top.

While you hold and rent: this is where residency status bites

Rental income is taxed differently depending on whether you are a resident or a non-resident, and the gap is large.

For a resident landlord, residential rental income up to KES 15 million a year is taxed under the simplified regime at 7.5% of gross rent. Withholding tax on rent for residents is 10%.

For a non-resident landlord, withholding tax on rental income is 30%. That is three times the resident rate, and it applies to the gross rent. If you are buying a Mombasa holiday let or a Nairobi apartment to rent out while living abroad, model your yield on the after-tax figure. A headline 8% gross yield is closer to 5.6% once 30% withholding is applied, before you count service charge, management, and vacancy.

This single fact changes the investment case for many non-resident buyers. It is the reason some structure their holding through a Kenyan operating company or take up tax residency, though both carry their own cost and complexity and need professional advice specific to your situation.

A new annual property tax

Kenya's 2025 Finance measures introduced a new 0.3% property tax, adding a recurring annual holding cost on top of county land rates and rates on the property. It is modest relative to stamp duty, but it is ongoing, so include it in your carrying-cost estimate for every year you hold.

County governments also levy annual land rates and, for many properties, service charges in managed developments. These vary by county and by development, so confirm the specific figures for your parcel before you buy.

When you sell: capital gains tax

Capital gains tax on disposal of property is 15% of the net gain, calculated as the sale price minus the acquisition cost and allowable expenses such as legal fees and improvement costs. The first KES 3 million of cumulative gains in a year of income is exempt.

Keep every receipt from the purchase and any improvements. Allowable expenses reduce the taxable gain directly, so good record-keeping is worth real money at sale. The CGT and stamp duty rates apply uniformly regardless of nationality, so on the buy and sell side a foreigner is treated the same as a local. It is the rental side where non-residents pay more.

A worked example

Take a non-resident buying a KES 20 million Nairobi apartment, renting it at KES 150,000 a month, and selling five years later for KES 26 million.

At purchase, stamp duty at 4% is KES 800,000. Annual gross rent is KES 1.8 million, on which 30% non-resident withholding is KES 540,000, leaving KES 1.26 million before service charge, management, and vacancy. The 0.3% annual property tax adds roughly KES 60,000 a year. At sale, the gross gain is KES 6 million, less the KES 3 million annual exemption and allowable expenses, with 15% CGT on the remaining taxable gain.

The point of the example is not the exact shillings. It is that the 30% rental withholding is the largest ongoing drag on a non-resident's return, and it has to be in your model from day one.

Practical steps

Register for a KRA PIN, which you will need to transact property at all. Use a Kenyan advocate and a tax adviser who works with non-residents, because the resident versus non-resident distinction and any double-taxation treaty between Kenya and your home country can materially change what you owe. Keep clean records of purchase price, stamp duty, legal fees, and improvements for the eventual CGT calculation.

Tax is only one layer of due diligence. Before any of it matters, the title has to be genuine and the developer has to actually deliver. Run an official Ardhisasa or Ministry of Lands search, and check the developer's completion record. Bektu (https://bektu.com) tracks whether developers finished their past projects, so your tax planning is not built on a unit that never gets built.

The headline for a non-resident buyer: budget 4% stamp duty upfront, expect 30% withholding on rent rather than the resident 10%, add the new 0.3% annual property tax, and plan for 15% CGT on gains above the KES 3 million annual exemption at sale. Get a tax adviser who knows the non-resident rules before you sign, not after.

This guide is general information, not personal tax advice. Rates and thresholds change, and your home-country tax and any treaty relief matter too, so confirm your position with a qualified Kenyan tax professional.
