🧩 Introduction

A limited company is a separate legal entity from its owners (shareholders).
It pays corporation tax on its profits before dividends are distributed.

Taxable profit is not the same as accounting profit — it must be adjusted for non-allowable expenses, non-taxable income, and capital allowances as per the Income Tax Act (Cap. 470).

Mr. Casper Amuto is the Finance Director of Damida Ltd.
The company employs him and provides several benefits. We will calculate his taxable income and tax liability as an individual employee of a corporation — to demonstrate corporate taxation from the employee benefit side.

🧮 Step 1: Determine Total Employment Income

Add all income and taxable benefits:

Component	Amount (Ksh)
Basic Salary	2,400,000
Bonus	120,000
Car Benefit	103,200
Employer-paid Mortgage Interest	180,000
Total Employment Income	2,803,200

---

🧾 Step 2: Deduct Allowable Deductions

Deduction	Amount (Ksh)	Note
Registered Pension Contribution	90,000	Allowable
Life Assurance Premium	72,000	Allowable
Total Allowable Deductions	162,000

Net Employment Income = 2,803,200 – 162,000 = 2,641,200

---

🧾 Step 3: Add Other Taxable Income

Income Type	Gross Amount (Ksh)	Taxability
Dividend (Damida Ltd.)	60,000 (net) → grossed up 60,000 ÷ 0.95 = 63,158	Final tax withheld → Not taxable again
Interest: Housing bonds	420,000	Tax-exempt
Interest: Treasury bills	120,000	Subject to withholding → Final tax
Interest: Matumaini Bank	85,000	Taxable
Dividend: Samoja Ltd.	95,000	Final tax withheld → Not taxable again
Rental income (inherited property)	520,000	Taxable
Hobby farming income	8,000	Taxable

✅ Add taxable ones only: 85,000 + 520,000 + 8,000 = 613,000

---

🧮 Step 4: Compute Total Taxable Income

Description	Amount (Ksh)
Employment income	2,641,200
Other taxable income	613,000
Total Taxable Income	3,254,200

---

🧮 Step 5: Compute Tax Liability

Apply 2010 Kenyan tax rates:

Income Band	Rate	Tax (Ksh)
First 121,968	10%	12,197
Next 114,912	15%	17,237
Next 114,912	20%	22,982
Next 114,912	25%	28,728
Balance (3,254,200 – 466,704 = 2,787,496)	30%	836,249
Gross Tax	—	917,393
Less: Personal Relief (13,944 p.a.)	—	(13,944)
Tax Payable	—	903,449

---

🧾 Step 6: Tax Already Paid

Source	Amount (Ksh)	Treatment
PAYE deducted by employer	72,000	Credit
Tax still due	903,449 – 72,000 = 831,449

✅ Mr. Amuto’s final tax payable is Ksh. 831,449

💡 Explanatory Notes

1. Car benefit — determined from prescribed benefit rates table.

2. Mortgage benefit — taxable on the interest portion paid by the employer.

3. Exempt incomes — e.g., housing development bond interest.

4. Final taxes — dividends and treasury bill interest with withholding tax are final.

5. Personal relief — always deductible after computing gross tax.
