Kenya capital gains tax is easy to underestimate because it sits inside a property transfer, not a normal monthly return. A seller may be focused on the sale agreement, land control consent, valuation, bank release, or advocate completion documents, while the Kenya Revenue Authority still expects the transferor to calculate and settle CGT before the transaction is fully lodged and registered.
As verified against KRA guidance on , the general Kenya CGT rate is 15% of the net gain. KRA describes it as a final tax, meaning the capital gain is not taxed again after the CGT has been paid. The charge normally applies to gains from transfer of property situated in Kenya, including transfers by individuals, companies, and partnerships.
This guide explains the practical 2026 workflow: what counts as a transfer, who pays, how the KRA net gain formula works, which costs can reduce the gain, which exemptions should be checked before filing, and how to connect the calculation to the Kenya Capital Gains Tax Calculator. It is written for planning and recordkeeping. It is not a substitute for legal or tax advice on a live conveyance, especially where trusts, family settlements, company restructures, inherited property, or non-resident ownership are involved.
What Kenya capital gains tax covers
KRA says CGT is levied on gains that accrue to a company, individual, or partnership on transfer of property situated in Kenya. The tax applies to gains from property transfers rather than to the full selling price. A taxpayer first works out the transfer value, subtracts allowable costs, and applies the tax rate to the net gain.
The current KRA page also lists two important cross-border rules effective from July 1, 2023. Gains from the sale of shares or comparable interests in foreign entities can be caught where more than 20% of their value is derived directly or indirectly from immovable property situated in Kenya. KRA also states that CGT can apply where a non-resident person holding more than 20% of the share capital of a Kenyan company directly or indirectly disposes of that interest.
That means the rule is not only about a simple individual sale of land. It can touch company shares, indirect interests, and non-resident disposals where Kenyan immovable property is the economic asset underneath the transaction. For routine owner-occupier and small investor transfers, the first question remains simpler: has an interest in Kenyan property been transferred, and has the transferor made a gain after allowable costs?
| Transaction type | CGT question to ask | Practical next step |
|---|---|---|
| Sale of Kenyan land or a building | Did the seller make a net gain after adjusted cost and incidental costs? | Calculate the gain before transfer documents are lodged. |
| Gift or non-cash transfer | Does KRA treat the transaction as a transfer even without cash consideration? | Check market value, exemption position, and documentation. |
| Company or partnership property disposal | Is the gain taxed as CGT or taxed elsewhere as trading income? | Confirm whether the entity is holding property as investment or dealing stock. |
| Indirect disposal through shares | Does the foreign or Kenyan company value come mainly from Kenyan immovable property? | Review the 20% ownership and value tests with advisers. |
| Family or estate transfer | Does a KRA exemption apply? | Document the family, estate, or settlement basis before filing. |
The 15% rate, who pays, and when the tax point happens
KRA's current capital gains tax page states that the rate is 15% of the net gain. The same guidance says CGT is declared and paid by the transferor of the property. In a normal sale, that means the seller, not the buyer. In a gift, exchange, surrender, or other transfer, the person transferring the property interest needs to check the CGT position even where cash is not the main consideration.
KRA describes the tax point as the registration of the transfer instrument in favour of the transferee, indicating transfer of interest from the seller to the purchaser. The page also says the due date for payment is the earlier of receipt of the full purchase price by the vendor or registration of the transfer instrument in favour of the transferee.
For planning, do not wait until the last conveyancing step. If the sale proceeds will settle a bank loan, pay agency fees, clear rates, or fund another purchase, ring-fence the possible CGT amount early. The tax is on the gain, but the cash must be available from the transaction.
The KRA formula for net gain
KRA gives the calculation as: Net gain = (transfer value minus incidental costs on transfer) minus adjusted cost. Adjusted cost includes acquisition cost, incidental costs on acquisition, and enhancement costs. In plain terms, you start with what the transferor receives or is treated as receiving, then deduct the documented cost base and documented transaction costs that KRA allows.
The Kenya CGT Calculator follows that structure. It is useful before the advocate prepares final completion numbers because it makes the cost categories explicit. The calculator cannot decide whether an exemption applies, but it can show how much the taxable gain changes when a cost is allowed or disallowed.
| Calculation layer | What goes into it | Document to keep |
|---|---|---|
| Transfer value | Sale proceeds, compensation, or other value received for the property interest | Sale agreement, valuation, completion statement, payment proof |
| Incidental transfer costs | Costs linked to finding a buyer, valuation for sale, legal transfer work, and related transfer expenses | Invoices, receipts, advocate fee note, agent invoice |
| Acquisition cost | Original purchase price or accepted acquisition value | Purchase agreement, transfer records, historical payment proof |
| Incidental acquisition costs | Costs incurred to acquire the property, where allowable | Advocate fee note, stamp duty proof, valuation records |
| Enhancement cost | Capital improvement costs that enhanced the property, not routine repairs | Contractor invoices, approvals, photos, payment records |
Allowable costs and the proof problem
KRA lists examples of allowable expenses for CGT purposes: acquisition or construction cost, loan or mortgage interest, advertising cost to find a buyer, valuation costs, legal fees, and enhancement costs. The list matters because CGT is charged on the net gain, not the gross sale proceeds.
The practical risk is proof. A transferor may know they renovated, extended, fenced, paved, or serviced the property, but KRA and the transaction advisers will need documents. Where the cost is material, keep the invoice, payment proof, contract, approval, and a short note tying the cost to the property. Routine maintenance and personal spending should not be mixed into the CGT worksheet unless a qualified adviser confirms the treatment.
For older properties, the records can be harder. Do not wait for the buyer's advocate to request completion documents before reconstructing the cost base. Start with the original purchase file, bank statements, stamp duty evidence, loan statements, improvement invoices, and valuation documents. If a property was inherited, gifted, transferred through a company, or moved between family members, the acquisition value question needs separate attention.
Exemptions to check before you calculate tax
Some transfers are exempt, and the exemption should be checked before the transferor assumes a 15% payment is due. KRA lists several exemption categories, including income taxed elsewhere in the case of property dealers, issuance by a company of its own shares and debentures, transfers for the purpose only of securing a debt or loan, transfers by a creditor returning security, and transfers by a personal representative to a beneficiary during administration of a deceased person's estate.
KRA also lists family and residence-related exemptions. These include transfer of assets between spouses, transfer of assets between former spouses as part of a divorce settlement or bona fide separation agreement, transfer of assets to immediate family, transfer to a company where spouses or a spouse and immediate family hold 100% shareholding, and a private residence where the individual owner has occupied the residence continuously for the three-year period immediately before the transfer.
For company groups, KRA lists an exemption for transfer of property as a result of internal restructuring within a group that has existed for at least 24 months, provided it does not involve transfer of property to a third party. This is a technical exemption. It should be documented carefully because the wrong restructuring sequence can create a tax issue that was avoidable with proper planning.
| Possible exemption | Key condition to document | Common weak spot |
|---|---|---|
| Private residence | Continuous occupation by the individual owner for the three-year period immediately before transfer | No proof of occupation or mixed personal and rental use |
| Spouse or former spouse transfer | Relationship basis, divorce settlement, or separation agreement where relevant | Transfer described loosely without legal support |
| Immediate family transfer | Family relationship and transfer purpose | Missing documentation for the family link |
| Estate administration | Transfer by a personal representative to a beneficiary | Transfer happens outside the estate administration file |
| Group restructuring | Group has existed for at least 24 months and no third-party transfer is involved | Corporate history and beneficial ownership are not clear |
Filing and payment deadlines
KRA's deadline table lists CGT filing on or before the date of lodgement of the application for transfer to the relevant Lands office, and CGT payment on or before the 20th day of the following month. KRA's dedicated CGT page adds that payment is due by the earlier of receipt of the full purchase price by the vendor or registration of the transfer instrument in favour of the transferee.
Those statements should be read operationally, not casually. In a property sale, the CGT position needs to be ready before transfer lodgement. If the full purchase price is received before registration, the payment timing can move earlier. If there is uncertainty, use the more conservative date shown in iTax or confirm directly with KRA or the transaction adviser.
Because Kenya tax deadlines can differ by tax head, do not copy the PAYE, VAT, or withholding tax deadline into a CGT file. PAYE is usually a monthly payroll workflow, VAT is a monthly return workflow, and CGT is transaction-based. For related Kenya tax context, use the Kenya withholding tax guide, the Kenya eTIMS expense validation guide, and the Africa property tax guide separately.
A practical iTax workflow for sellers and advisers
KRA says CGT payment should be initiated online through iTax, after which the taxpayer receives a payment slip and presents it with the tax due at an appointed bank. The payment slip expires within 30 days. A clean workflow should start earlier than the payment slip, because the numbers need to reconcile to the conveyancing file.
- Confirm the transferor, property, transfer value, expected completion date, and whether the transaction is a sale, gift, exchange, family transfer, estate transfer, company restructuring, or indirect share disposal.
- Check exemptions before calculating tax. Save the legal basis and supporting documents for the file.
- Build the cost base from acquisition cost, incidental acquisition costs, and enhancement costs. Exclude weak or unsupported items until they are confirmed.
- Enter the transfer value, transfer costs, and adjusted cost in the Kenya CGT Calculator to produce a planning number.
- Review the calculation with the advocate, accountant, or tax adviser responsible for the transfer file.
- File through iTax and generate the payment slip when the transaction is ready for payment.
- Pay through the accepted KRA channel and keep the payment acknowledgement with the completion documents.
- Save the final CGT worksheet, invoices, receipts, sale agreement, transfer documents, and exemption evidence for future audit support.
Formula walkthrough based on the KRA structure
This is a formula walkthrough, not a fictional taxpayer story. It uses the KRA net gain structure and shows how the 15% rate applies once the transfer value and allowable costs are known.
| Line item | Amount | Calculation role |
|---|---|---|
| Transfer value | KES 12,000,000 | Starting value for the disposal |
| Incidental costs on transfer | KES 350,000 | Deduct from transfer value |
| Acquisition cost | KES 7,000,000 | Part of adjusted cost |
| Incidental acquisition costs | KES 280,000 | Part of adjusted cost |
| Enhancement costs | KES 900,000 | Part of adjusted cost |
First subtract transfer costs from transfer value: KES 12,000,000 minus KES 350,000 equals KES 11,650,000. Then add acquisition cost, incidental acquisition costs, and enhancement costs to get adjusted cost: KES 7,000,000 plus KES 280,000 plus KES 900,000 equals KES 8,180,000.
The net gain is KES 11,650,000 minus KES 8,180,000, which equals KES 3,470,000. At 15%, the CGT planning amount is KES 520,500 before any exemption, adjustment, or adviser-confirmed treatment changes the position. If an exemption applies, the filing and evidence workflow changes. If a cost is unsupported, the taxable gain may be higher.
