Section 4 -- Worked examples
Example 1 -- Standard self-employed, mid-range
Input: Resident, revenue KES 3,000,000, expenses KES 1,200,000, insurance premiums KES 100,000, instalment tax KES 150,000. Computation: Taxable = KES 1,800,000. Tax = 28,800 + 25,000 + 423,600 = KES 477,400. Less personal relief 28,800. Less insurance relief min(15,000, 60,000) = 15,000. Net = KES 433,600. Less instalment KES 150,000. Due = KES 283,600.
Example 2 -- Below personal relief
Input: Taxable income KES 200,000. Computation: Tax = 10% x 200,000 = KES 20,000. Less relief KES 28,800. Payable = KES 0.
Example 3 -- Turnover tax
Input: Non-professional trader, turnover KES 8,000,000. Computation: TOT = 1.5% x KES 8,000,000 = KES 120,000/year.
Example 4 -- Presumptive vs normal
Input: Small trader, turnover KES 500,000, expenses KES 350,000. Computation: Normal: profit KES 150,000. Tax = 15,000 - 28,800 relief = KES 0. Presumptive: KES 15,000. Normal is better.
