Understanding Bonus and 13th Month Pay in Kenya
_1.jpeg)
In Kenya, 13th month pay and bonuses can boost your take-home by 8-12% but trigger specific KRA tax rules that most employees overlook. This extra pay often acts as a contractual double December pay under employment laws. It covers a large share of formal sector workers.
The legal basis comes from the Employment Act 2007, which supports such payments in contracts. Employers must clearly define these in your employment contract or HR policies. This ensures transparency in your remuneration package.
These payments form part of your taxable income under the Income Tax Act. Kenyan employers handle PAYE withholding on them, affecting your net pay. Understanding this helps you plan for tax bands and deductions like NHIF and NSSF.
Next, we break down what counts as 13th month pay and common bonus types. This knowledge aids in checking your payslip and using the iTax portal for accurate tax filing.
What Constitutes 13th Month Pay
13th month pay is your full basic salary, excluding allowances, paid in December. It stems from your contract and aligns with common practices in Kenya. This December pay boosts end-of-year finances for many.
Per the Income Tax Act, it includes only basic salary, not housing or medical allowances. For example, if your monthly basic is KSh 50,000, your 13th cheque is KSh 50,000, not your full KSh 80,000 package. Check your payslip breakdown for this separation.
KRA rulings confirm this treatment, ensuring taxable income reflects true earnings. Employers compute it as part of employment income, applying progressive tax rates. This avoids disputes during year-end P9 form issuance.
Review your salary structure to confirm eligibility. If unclear, ask HR about your 13th cheque policy. Proper understanding prevents surprises in tax computation and statutory deductions.
Types of Bonuses Employers Offer
Kenyan employers offer various bonus types to motivate staff, each with unique tax rules. These fall under income tax as employment income. Knowing them helps track your cumulative earnings for PAYE.
Performance bonuses reward targets, while commissions tie to sales. Profit shares distribute company gains, and retention bonuses secure loyalty. Ad-hoc ones address special cases.
| Bonus Type | Prevalence | Tax Treatment | Example Amount |
|---|---|---|---|
| Performance (monthly target bonus) | Common in sales and targets | Fully taxable under PAYE | One month's basic salary |
| 13th Month | Widespread in formal sector | Taxed as basic salary | Equal to monthly basic |
| Profit Share | In profitable firms | Taxed progressively | Portion of annual profits |
| Retention | For key staff | Added to taxable income | One month's salary |
| Commission | Sales roles | Withheld via PAYE | Percentage of sales value |
Finance Act amendments clarify bonus taxation, treating them as regular pay. Use a PAYE calculator to estimate impact on your tax bands. Employers remit these via monthly returns.
Kenyan PAYE Tax System Basics
Kenya's PAYE uses 5 progressive bands up to 37.5%, with KSh 28,000 entry threshold. Pay As You Earn means employers withhold tax monthly via the KRA iTax portal. This cumulative system tracks year-to-date earnings to prevent bracket creep, as outlined in the Income Tax Act Cap 470.
Employers calculate taxable income from gross pay minus statutory deductions like NHIF, NSSF, and pension contributions. They apply personal relief of KSh 2,400 monthly before final tax. Bonuses and 13th month pay integrate into this cumulative total, often pushing employees into higher bands.
For bonus tax and 13th month pay, Kenyan employers treat them as employment income. The system averages tax over the year to smooth out spikes from end-of-year payments. Check your payslip for accurate withholding and year-end P9 form for total liability.
This setup ensures tax compliance with monthly remittances to KRA. Employees avoid large year-end bills through progressive withholding. Understanding these basics helps plan your remuneration package effectively.
Progressive Tax Bands (2024 Rates)
For 2024, Kenya's tax bands start at 10% (KSh 28,001-36,000), jumping to 37.5% above KSh 800,001 per Finance Act 2023. These progressive tax bands apply to monthly cumulative earnings after deductions. Kenyan employers use them for salary, bonuses, and 13th cheques via the iTax portal.
| Monthly Band (KSh) | Rate | Marginal Tax on Band (KSh) | Example: KSh 100k Salary |
|---|---|---|---|
| 0 - 28,000 | 0% | 0 | No tax |
| 28,001 - 36,000 | 10% | 800 max | 800 tax |
| 36,001 - 69,000 | 25% | 8,250 max | 5,450 tax |
| 69,001 - 288,000 | 30% | 65,400 max | 24,900 tax |
| 288,001+ | 37.5% | Remaining | 3,275 tax |
Annual equivalents double monthly figures: first band up to KSh 336,000 at 0%. For a KSh 100,000 monthly salary, total tax hits about KSh 34,425 yearly before relief, yielding an effective rate around 24.1% after adjustments. Add a performance bonus, and it shifts more into the 30% or 35% band.
Experts recommend using a PAYE calculator for precise tax computation on double salary in December. For instance, a KSh 50,000 bonus on KSh 80,000 base pay averages the tax hit. Always verify via your employer's payroll software like Sage or QuickBooks Kenya.
Tax Treatment of 13th Month Pay
Your 13th month pay gets taxed via KRA's averaging method across 13 months, potentially saving on tax compared to a straight top rate application. The Kenya Revenue Authority treats it as employment income under Section 5(2) of the Income Tax Act. This method computes tax separately then averages it, as detailed in the 16th Schedule, to prevent a December tax shock.
Kenyan employers must follow this rule for end of year bonuses like the 13th cheque. Without averaging, a large December payout could push you into the 37.5% tax band, increasing your withholding tax. The averaging spreads the tax burden across the fiscal year.
For example, if your annual earnings total KSh 800,000 including the bonus, the employer divides by 13 to find a monthly equivalent. They then apply progressive tax bands and multiply back by 13 for the final liability. This ensures fair tax computation on cumulative earnings.
Employees see this on their December payslip, with adjustments for personal relief, insurance relief, and statutory deductions like NHIF and NSSF. Check your P9 form at year-end via the iTax portal to verify accuracy.
Taxed as Regular Salary

13th month pay equals regular salary for tax purposes: same bands, same reliefs, just spread across the fiscal year. Kenyan employers aggregate it with Jan-Dec earnings under PAYE rules. This treats the annual bonus as part of your total taxable income.
The formula works by taking annual total divided by 13 months, then applying the relevant tax band rate. For instance, with KSh 800,000 annual pay (KSh 61,538 monthly plus bonus), the effective rate might land at 28% after averaging. This beats 35% if taxed separately in December.
Tax reliefs apply fully, including personal relief of KSh 2,400 monthly and pension deductions. Employers deduct NHIF and NSSF from gross pay before computing. Your net pay reflects the averaged monthly tax.
This method supports tax compliance and avoids penalties for under-withholding. Review your salary structure to understand how bonuses fit into your remuneration package.
Separate PAYE Computation Rules
KRA's 13-month averaging formula divides total earnings by 13, applies progressive rates, then multiplies back by 13. This follows the Income Tax Act 16th Schedule and KRA Practice Manual Module 5. Employers use it for precise bonus taxation on double salary in December.
Follow these steps for calculation:
- Sum Jan-Dec cumulative earnings including the 13th pay.
- Divide by 13 to get monthly equivalent.
- Apply PAYE bands: up to 10% on lower bands, rising to 37.5% on top.
- Multiply computed tax by 13 for annual liability.
- Apportion the December portion to your payslip after reliefs and deductions.
For an Excel formula, use: =((SUM(earnings_range)/13 * tax_rate_function) * 13) - reliefs, adjusted for brackets. Test with your gross pay figures. This yields accurate annual tax liability.
Employers remit via monthly returns using their IR number. Employees confirm via KRA iTax or P9 form to spot overpaid tax for refunds. It ensures smooth tax filing and compliance with employer obligations.
Tax Treatment of Performance Bonuses
Performance bonuses paid mid-year get bundled into that month's PAYE at marginal rates, potentially a 35% hit for senior staff. Unlike 13th month pay averaging, ad-hoc bonuses trigger immediate higher-bracket tax under Section 81 of the Income Tax Act. Kenyan employers must withhold via the iTax portal by the 9th of the next month.
This progressive tax approach means your taxable income jumps suddenly, pushing you into a higher tax band. For instance, a Q3 bonus added to regular salary can spike your monthly tax. Employers handle the tax calculation but employees feel the net pay drop.
Kenya Revenue Authority rules require accurate withholding tax on this employment income. Late filing risks penalties, so payroll teams use tools like QuickBooks Kenya or Sage payroll. Plan ahead to avoid cashflow shock from the higher employer deductions.
Check your payslip for proper inclusion of the performance bonus in gross pay. Statutory deductions like NHIF deduction, NSSF contribution, and personal relief apply as usual. This ensures compliance with tax policy in Kenya.
Included in Monthly PAYE
KSh 100,000 Q3 bonus on KSh 80,000 salary equals KSh 28,500 tax that month at 35% marginal versus KSh 12,000 normal PAYE. The bonus forms part of cumulative earnings, hitting the top tax band. This creates a sharp rise in tax computation for that period.
| Scenario | Normal Month | Bonus Month | Tax Impact |
|---|---|---|---|
| Gross Pay | KSh 80,000 | KSh 180,000 | +KSh 100,000 bonus |
| PAYE Tax | KSh 12,000 | KSh 28,500 | +KSh 16,500 tax |
| Net Pay | KSh 68,000 (approx) | KSh 151,500 (approx) | Effective 16% extra tax on bonus |
Employers update payroll software, file Form P10, and remit by the 9th via KRA iTax. After statutory deductions like pension deduction and insurance relief, the tax on double pay still stings. Expect a cashflow shock without savings.
KRA penalty for late remittance is 5% plus 1% per month. Use a PAYE calculator to preview impacts on your remuneration package. Review your employment contract for bonus policy details.
Tax Reliefs and Exemptions
Tax reliefs apply proportionally to bonuses and 13th month pay in Kenya. You can claim them via the iTax portal or through your employer's payroll system. Statutory deductions like NHIF and NSSF reduce your taxable bonus first.
KSh 28,800 annual personal relief plus insurance relief can cut your bonus tax by KSh 7,200-12,000 yearly. Kenyan employers must factor these into PAYE calculations for employment income. This lowers your overall tax liability on end-of-year bonuses or performance bonuses.
Reliefs work on cumulative earnings, spreading benefits across the tax year. For a December double salary, ensure your employer syncs reliefs before withholding tax. The Kenya Revenue Authority allows adjustments via payslips and P9 forms.
Common reliefs include personal relief, insurance relief, and pension deductions. These apply to taxable income from salary bonuses or 13th cheques. Always check your tax bands to see the impact on progressive tax rates.
Personal Relief Application
KSh 2,400 monthly personal relief (KSh 28,800/year) applies BEFORE bonus tax calculation. This relief reduces your taxable income proportionally for bonuses and 13th month pay. Kenyan employers prorate it based on remaining months in the fiscal year.
Calculation example: For a KSh 100k bonus with 6 months left, relief is KSh 16,800 (KSh 2,400 × 7). This lowers your entry into higher tax brackets. Use this for performance bonuses or annual bonuses to minimise PAYE.
To claim on iTax portal: Log in with your KRA PIN, update reliefs under personal details, then your employer syncs it. Verify via monthly payslips for accurate tax computation. This ensures compliance with Income Tax Act rules.
If your employer overlooks it, file for year-end tax adjustment to recover overpaid tax. Personal relief benefits resident employees most in lower tax bands. Track it to avoid underpaid tax penalties.
Insurance Relief on Bonuses

15% insurance relief (max KSh 5,760/year) on life/A&H premiums applies to bonus income too. Premiums paid qualify under Section 45 of the Income Tax Act. This relief caps at KSh 480 monthly, including bonus months.
Formula: Premiums × 15% (capped KSh 480/mo). Example: KSh 4,000 monthly premium gives KSh 600 relief per month, even for 13th cheque periods. Submit receipts to HR or employer for payroll inclusion.
Upload process: Provide premium receipts to your employer's HR, who inputs into payroll software like Sage. They remit adjusted PAYE to KRA. This reduces net tax on double salary in December.
Relief applies to fringe benefits and employment income proportionally. Ensure premiums cover qualified policies for maximum benefit. Experts recommend verifying with payslips to confirm tax averaging on bonuses.
Practical Tax Calculation Examples
Real example: Teacher earning KSh 45,000/mo + KSh 45,000 13th cheque pays only KSh 2,850 extra tax thanks to averaging.
Kenyan employers use tax averaging for bonus tax and 13th month pay. This spreads the taxable income over the year to apply correct tax bands. It avoids pushing employees into higher progressive tax brackets unfairly.
These examples show step-by-step calculations for PAYE on gross pay, deductions, and net pay. They cover junior, middle, and senior levels with matching bonuses. Use a PAYE calculator or Excel tool for your own figures.
Statutory deductions include NSSF, NHIF, pension, and personal relief of KSh 2,400 monthly. Tax rates follow Kenya Revenue Authority brackets from 10% to 37.5%. Always check your payslip for cumulative earnings.
Example 1: Junior Employee (KSh 40,000 Salary + KSh 40,000 Bonus)
This junior worker gets monthly gross pay of KSh 40,000 plus a performance bonus of KSh 40,000. Employment income totals KSh 480,000 annually before bonus averaging. Deductions reduce taxable income step by step.
First, calculate monthly statutory deductions like NSSF contribution up to KSh 2,160 and NHIF around KSh 1,200. Then apply insurance relief and personal relief. Bonus triggers bonus tax averaging for fair PAYE.
| Step | Amount (KSh) | Notes |
|---|---|---|
| Gross Pay (Monthly) | 40,000 | Base salary |
| Statutory Deductions | -4,000 | NSSF, NHIF, Pension |
| Taxable Income | 36,000 | After deductions |
| PAYE (10% band) | -1,440 | Monthly tax |
| Net Pay (Monthly) | 34,560 | Take-home |
| Bonus Gross | 40,000 | 13th month pay |
| Tax on Bonus (Averaged) | -4,000 | Effective rate after averaging |
| Net Bonus | 36,000 | After tax |
Total extra tax on bonus stays low due to lower tax band. Employer withholds via monthly remittance to KRA.
Example 2: Middle-Level Employee (KSh 100,000 Salary + KSh 100,000 Bonus)
Middle managers earn KSh 100,000 gross monthly with an equal annual bonus. Annual income hits KSh 1.3 million after bonus. Tax calculation uses mid-level tax brackets like 25% and 30%.
Deductions cover higher NHIF deduction, NSSF cap, and pension up to 15%. Personal relief applies fully. 13th cheque averaging prevents jump to top bands.
| Step | Amount (KSh) | Notes |
|---|---|---|
| Gross Pay (Monthly) | 100,000 | Salary structure |
| Statutory Deductions | -12,000 | Including fringe benefits tax |
| Taxable Income | 88,000 | Pre-tax |
| PAYE (25-30% bands) | -15,200 | Progressive tax |
| Net Pay (Monthly) | 72,800 | After relief |
| Bonus Gross | 100,000 | End of year bonus |
| Tax on Bonus (Averaged) | -18,000 | Blended rate |
| Net Bonus | 82,000 | Received |
Payroll software like Sage handles this accurately. Check P9 form for year-end reconciliation.
Example 3: Senior Employee (KSh 300,000 Salary + KSh 300,000 Bonus)
Senior staff with KSh 300,000 monthly remuneration plus matching executive bonus face top rates. Total pay exceeds KSh 3.9 million yearly. Income Tax Act applies 35-37.5% on higher portions.
Higher pension deduction and NHIF apply. Taxable allowance like housing boosts gross. Averaging softens the top tax band impact on double pay.
| Step | Amount (KSh) | Notes |
|---|---|---|
| Gross Pay (Monthly) | 300,000 | Includes allowances |
| Statutory Deductions | -25,000 | NSSF, NHIF, Pension |
| Taxable Income | 275,000 | Adjusted |
| PAYE (30-37.5% bands) | -85,000 | High bracket tax |
| Net Pay (Monthly) | 190,000 | Post-relief |
| Bonus Gross | 300,000 | Salary bonus |
| Tax on Bonus (Averaged) | -95,000 | Higher effective rate |
| Net Bonus | 205,000 | Final amount |
Such cases highlight employer obligations for correct withholding. Use KRA iTax portal for tax filing and adjustments.
Frequently Asked Questions
