Computing Taxable Income for Individuals and Corporations

Taxable income computation is essential for both individuals and corporations in Kenya. It involves adjusting the reported profit or loss by adding back disallowable expenses and deducting allowable expenses. Disallowable expenses include private expenses, depreciation on non-qualifying assets, and certain legal fees. Allowable expenses typically include business-related costs such as salaries, rent, and utilities.

For corporations, the corporate tax rate is currently set at 30% as per the Income Tax Act. Individuals are taxed based on progressive rates, with the highest rate being 30% for income exceeding KES 688,000 annually. It is crucial to ensure that all adjustments are accurately reflected in the income tax computation schedule, which ultimately determines the tax payable or refundable.

When preparing the computation, ensure to follow the guidelines provided in the Income Tax Act and the Companies Act 2015. This includes recognizing capital allowances for qualifying assets, which can significantly reduce taxable income. The computation should also reflect any distributions to partners or shareholders, as these affect the taxable income of the respective parties involved.

Key points to remember

  • Adjust reported profit by adding disallowable expenses.
  • Corporate tax rate is 30%; individuals are taxed progressively.
  • Recognize capital allowances to reduce taxable income.
  • Ensure compliance with Income Tax Act and Companies Act 2015.
  • Accurate computation determines tax payable or refundable.

Worked example

Computation of Taxable Income for ABC Ltd. for the Year Ended 31 Dec 2021

Reported Profit: KES 3,600,000

Add Back Disallowable Expenses:

  • General expenses (listing costs): KES 100,000
  • Debenture interest: KES 150,360
  • Directors' fees: KES 507,720
  • Legal expenses: KES 255,120

Total Additions: KES 1,013,200

Adjusted Profit:
Reported Profit + Additions
= KES 3,600,000 + KES 1,013,200
= KES 4,613,200

Less Allowable Expenses:

  • Salaries and wages: KES 541,500
  • Electricity and telephone: KES 194,700
  • Repair and maintenance: KES 147,200
  • General insurance: KES 235,500

Total Allowable Expenses: KES 1,119,900

Taxable Income:
Adjusted Profit - Allowable Expenses
= KES 4,613,200 - KES 1,119,900
= KES 3,493,300

Tax Payable:
Taxable Income × Corporate Tax Rate
= KES 3,493,300 × 30%
= KES 1,047,990

Lesson 2: Income Tax Computation: Allowable Deductions and Exemptions

Objective: Identify and apply allowable deductions and exemptions.

In computing taxable income for individuals and entities in Kenya, it is essential to identify allowable deductions and exemptions as per the Income Tax Act, 2015. Allowable deductions reduce the taxable income, while exemptions may exclude certain income from taxation altogether.

Common allowable deductions include:

  1. Business Expenses: These are necessary expenses incurred in the production of income. Examples include salaries, rent, and utilities. However, personal expenses, such as private rent or salaries paid to partners, are disallowed.
  2. Capital Allowances: Instead of depreciation, businesses can claim capital allowances on qualifying assets. For instance, furniture may attract a wear and tear allowance of 12% or 20%, depending on the asset type.
  3. Interest on Loans: Interest paid on loans taken for business purposes is deductible.
  4. Legal and Professional Fees: Expenses incurred for legal advice related to business operations are generally allowable.

Exemptions can include certain types of income, such as:

  • Dividends from Kenyan resident companies: These are generally exempt from tax.
  • Gains from the sale of capital assets: If the asset qualifies under the capital gains tax provisions, it may be exempt.

Understanding these deductions and exemptions is crucial for accurate tax computation and compliance with the Kenya Revenue Authority (KRA) requirements.

  • Identify allowable deductions under the Income Tax Act, 2015.
  • Disallowed expenses include personal and partner salaries.
  • Claim capital allowances instead of depreciation for qualifying assets.
  • Interest on business loans is deductible.
  • Certain income types may be exempt from taxation.

Lesson 3: Distinguishing Income Sources for Tax Computation

Objective: Distinguish between different income sources for tax purposes.

In Kenya, income tax is governed by the Income Tax Act, 2015. Understanding different income sources is essential for accurate tax computation. Income can be categorized into several sources: employment income, business income, rental income, and investment income. Each category has specific rules regarding allowable deductions and tax treatment.

  1. Employment Income: This includes salaries, wages, bonuses, and allowances. The prevailing PAYE rates apply, and deductions for contributions to retirement schemes are allowed.

  2. Business Income: This encompasses profits from trade or profession. Allowable expenses such as operational costs, wear and tear, and specific deductions must be accurately computed. For instance, wear and tear on assets is calculated based on the rates provided under the Income Tax Act.

  3. Rental Income: Income from property leasing is taxable. Allowable deductions include property maintenance costs, management fees, and depreciation of the property.

  4. Investment Income: This includes dividends, interest, and royalties. Different tax treatments apply, such as withholding tax on dividends and interest income.

Understanding these distinctions is crucial for preparing accurate tax computations and ensuring compliance with KRA regulations.

  • Identify income sources: employment, business, rental, investment.
  • Apply correct PAYE rates for employment income.
  • Deduct allowable expenses for business income.
  • Calculate wear and tear based on Income Tax Act rates.
  • Understand tax treatments for investment income.

Example: Income Tax Computation

Assume the following for a taxpayer for the year ended 31 December 2026:

  • Employment Income: KES 1,200,000
  • Business Income: KES 800,000
  • Rental Income: KES 500,000
  • Investment Income: KES 200,000

Allowable Deductions:

  • Business Expenses: KES 300,000
  • Rental Expenses: KES 100,000

Step 1: Compute Taxable Income

Employment Income:
KES 1,200,000
Business Income:
KES 800,000
Less: Allowable Business Expenses
(KES 300,000)
Net Business Income:
KES 500,000
Rental Income:
KES 500,000
Less: Allowable Rental Expenses
(KES 100,000)
Net Rental Income:
KES 400,000
Investment Income:
KES 200,000

Total Taxable Income:

KES 1,200,000 + KES 500,000 + KES 400,000 + KES 200,000 = KES 2,300,000

Summary of Taxable Income:

| Source of Income | Amount (KES) | |------------------------|---------------| | Employment Income | 1,200,000 | | Net Business Income | 500,000 | | Net Rental Income | 400,000 | | Investment Income | 200,000 | | Total Taxable Income | 2,300,000 |
