Capital Gains Tax in Kenya (2026): Everything Property Sellers Need to Know

If you are selling land, a home, apartments, commercial property, or even company shares linked to real estate in Kenya, understanding Capital Gains Tax (CGT) is essential.

Many Kenyans only discover CGT when they are already finalizing a property transfer — and by then, delays, penalties, and disputes with the Kenya Revenue Authority (KRA) can become expensive.

This guide explains:

• What Capital Gains Tax is
• Who pays it
• Current CGT rates in Kenya
• Exemptions many sellers miss
• How CGT is calculated
• Real examples
• Important court rulings involving KRA
• Practical steps to stay compliant

According to Kenya Revenue Authority (KRA), CGT is charged on gains arising from the transfer of property situated in Kenya.

What Is Capital Gains Tax (CGT)?

Capital Gains Tax is a tax charged on the profit (gain) made when selling or transferring property.

The tax applies to:

• Land
• Residential houses
• Commercial buildings
• Apartments
• Shares linked to immovable property
• Some business assets

Importantly, CGT is charged on the gain, not the total selling price.

The current CGT rate in Kenya is:

15% of the Net Gain

This rate was increased from 5% to 15% beginning January 2023.

When Does CGT Become Payable?

One of the most misunderstood parts of Kenyan property transactions is the tax point.

KRA states that CGT becomes payable:

Upon registration of the transfer instrument in favour of the buyer.

This means:

• Signing a sale agreement alone is not enough
• Receiving a deposit is not the tax trigger
• Registration of transfer is the critical point

This distinction became very important in a major tax dispute case involving KRA.

A Real Court Case: Asvin vs Commissioner of Domestic Taxes

In the case of Asvin v Commissioner of Domestic Taxes (2024), the taxpayer argued that CGT should apply at the older 5% rate because payment had been initiated earlier.

However, the Tax Appeals Tribunal ruled that the applicable rate depended on the registration date of the transfer, not when payment discussions began. Since registration happened after the 15% rate became effective, KRA’s position prevailed.

Why This Case is Important

This ruling teaches property sellers an important lesson:

• Delays in transfer registration can increase tax liability
• Timing matters significantly in property transactions
• Sellers should coordinate closely with advocates and land registries

How Is Capital Gains Tax Calculated?

KRA uses the following formula:

Net Gain = Selling Price – (Acquisition Cost + Incidental Costs + Improvement Costs)

Example of CGT Calculation in Kenya

Example:

A seller:

• Bought land for KSh 4 million
• Spent KSh 500,000 on fencing and improvements
• Paid KSh 200,000 in legal and valuation fees
• Sells the property for KSh 8 million

Calculation:

CGT Payable:

15% × 3,300,000 = KSh 495,000

Allowable Expenses Many Sellers Forget

KRA allows certain deductions that can reduce taxable gains.

These include:

• Legal fees
• Valuation fees
• Advertising costs
• Construction costs
• Renovation expenses
• Loan or mortgage interest
• Agent commissions
• Survey fees

Keeping proper records can significantly reduce your CGT burden.

Important CGT Exemptions in Kenya

Many transactions legally qualify for exemption.

1. Sale of Property Below KSh 3 Million

Transfers where the value does not exceed KSh 3 million are exempt.

2. Primary Residence Exemption

If you have occupied your home continuously for at least three years before selling, the gain may be exempt from CGT.

This exemption is extremely important for homeowners in areas like Karen, Kilimani, Syokimau, and Mombasa where property appreciation can be substantial.

3. Transfers Between Spouses or Immediate Family

KRA exempts certain family transfers including:

• Spousal transfers
• Divorce settlements
• Transfers to immediate family
• Some inheritance transactions

4. Corporate Restructuring Exemptions

Some company restructuring transactions may qualify for exemption if they meet KRA requirements and public-interest thresholds.

However, KRA closely monitors these arrangements to prevent abuse.

Important Warning: KRA Verification Has Increased

KRA has strengthened digital monitoring of property transactions through iTax integration. Exemptions are no longer automatically accepted.

Transactions flagged as exempt now undergo verification and approval.

This means:

• Documentation is critical
• Unsupported exemption claims may be rejected
• Sellers should maintain clear records

Common Mistakes Property Sellers Make

Assuming CGT Is Based on Sale Price

CGT is based on the net gain, not total proceeds.

Failing to Keep Supporting Documents

Missing:

• Sale agreements
• Valuation reports
• Construction receipts
• Legal invoices

Can increase your assessed tax burden.

Delaying Registration

As shown in the Asvin case, registration timing can affect applicable tax rates.

Assuming Exemptions Are Automatic

KRA may reject unsupported exemption claims. Sellers must prove eligibility.

What Happens If You Disagree With KRA?

Tax disputes involving CGT are becoming more common in Kenya.

Recent taxpayer discussions and tribunal decisions show that some KRA assessments have been challenged successfully where calculations ignored acquisition costs or procedural fairness.

However, tax experts strongly recommend:

• Responding to KRA notices immediately
• Filing objections within statutory timelines
• Keeping accurate records
• Using qualified tax professionals or advocates

Step-by-Step Guide: How to Handle CGT Properly in Kenya

Step 1: Gather Property Documents

Prepare:

• Title deed
• Sale agreement
• Purchase agreement
• Valuation reports
• Receipts for improvements
• Legal fee invoices

Step 2: Calculate the Net Gain

Determine your actual taxable gain after allowable deductions.

Step 3: File Through iTax

CGT declarations are made online through the KRA iTax system.

Step 4: Make Payment

Payment can be made via:

• Bank transfer
• RTGS
• Designated banks

Step 5: Retain All Records

KRA may request evidence later, especially for exempt transactions.

Capital Gains Tax has become one of the most important parts of property transactions in Kenya.

Whether you are:

• Selling land
• Transferring inherited property
• Restructuring assets
• Selling investment apartments
• Disposing of commercial buildings

Understanding CGT early can save you millions in unnecessary penalties, delays, or disputes.

The smartest property investors in Kenya no longer treat CGT as an afterthought — they plan for it before entering any transaction.

And in a market where property values continue to rise, proper tax planning is becoming just as important as choosing the right location.
