December in Nigeria often comes with the question, “Will we get 13th month this year?” Some workers receive an extra month’s pay; others get a performance bonus in the first quarter; many get nothing. This guide explains what 13th-month pay and bonuses actually are, whether your employer is obliged to pay them, how they are taxed under the 2026 rules, and how to plan the money so it does not vanish by mid-January.
What is 13th-month pay?
A 13th-month salary is an extra payment, usually equal to one month’s basic or gross salary, paid once a year, often in November or December. It spreads 13 payments across a 12-month year. Some employers pay it as a fixed contractual benefit; others call it a “Christmas bonus” and pay it at their discretion.
What is a bonus?
A bonus is any extra payment on top of regular salary. Common types in Nigerian workplaces include:
- Performance bonus: tied to your appraisal rating or targets.
- Profit-share bonus: linked to company results, often paid after year-end accounts.
- Sales commission: a percentage of what you sell.
- Sign-on or retention bonus: paid to join or to stay, often with clawback conditions.
- Leave allowance: technically an allowance rather than a bonus, but it behaves similarly in your budget.
Is my employer required to pay 13th month?
We have not found any provision in Nigeria’s Labour Act requiring private employers to pay a 13th-month salary. In practice, your entitlement depends on:
- Your employment contract or offer letter. If it lists 13th-month pay as part of your annual package, it is a contractual right.
- The staff handbook or condition of service. Many organisations put bonus policies here.
- A collective agreement negotiated by a union in your sector.
- Established practice. Where a payment has been made consistently for years, there may be an argument it has become an implied term. That is a legal question for a lawyer, not something to assume.
Read your offer letter. If it says “annual gross: 13 × monthly gross”, the 13th month is part of your pay, not a gift. If it says bonuses are “discretionary”, the employer can decide not to pay.
How 13th-month pay and bonuses are taxed
Bonuses and 13th-month pay are generally part of employment income, so they are added to your annual gross for PAYE. Under the Nigeria Tax Act 2025, personal income is taxed in bands: 0% on the first ₦800,000 of chargeable income, then 15%, 18%, 21%, 23% and 25% on higher slices (PwC Tax Summaries).
Because the bands are marginal, the bonus is taxed at your top rate, not your average rate. If most of your income already sits in the 15% band, each extra naira of bonus is taxed at about 15% until it crosses into the 18% band.
Why the deduction can look bigger in the bonus month
Payroll systems often calculate PAYE month by month. In the month a bonus is paid, the system may treat your income as unusually high and deduct more. Over the full year, PAYE should be reconciled to the correct annual figure. If the bonus month deduction looks extreme, ask payroll for a breakdown.
Is pension deducted from bonus?
The Pension Reform Act 2014 calculates contributions on monthly emoluments, which PenCom describes as including at least basic salary, housing and transport allowances (PenCom FAQ). Whether a bonus attracts pension depends on how your employer defines emoluments. Check your payslip.
Illustration (invented figures)
An employee earns ₦250,000 gross a month (₦3,000,000 a year) and receives a 13th-month payment of ₦250,000. After an 8% pension deduction and no other reliefs, chargeable income without the bonus is ₦2,760,000, which sits entirely in the 15% band. Adding ₦250,000 bonus (assume no pension on it) gives ₦3,010,000. The first ₦240,000 of the bonus is taxed at 15% (₦36,000) and the last ₦10,000 at 18% (₦1,800). Tax on the bonus is about ₦37,800, leaving roughly ₦212,200.
A plan for your 13th month or bonus
A bonus feels like free money, so it is the easiest income to waste. Decide the split before it arrives. A simple framework:
| Priority | Suggested use |
|---|---|
| 1. January survival | Set aside enough for January rent instalment, school fees or transport if December spending usually leaves you short. |
| 2. Expensive debt | Clear loan app balances, overdrafts or salary advances first. See our guide to getting out of loan app debt. |
| 3. Emergency fund | Top up toward 3–6 months of essential expenses. See our emergency fund guide. |
| 4. Big planned costs | Next rent, school fees or a planned purchase. See budgeting for school fees. |
| 5. Enjoyment | A fixed, guilt-free amount for Christmas, family and travel. |
One practical rule: give yourself a fixed enjoyment percentage you agreed on in advance (for example 20–30%), and send the rest to its destination on the day the money arrives.
Plan for family expectations
In many Nigerian families, December is when relatives expect support. That is part of life, but it should be in the plan, not a surprise. Write down who you will support and how much, and treat it as a budget line. If requests exceed it, you can say, “This is what I budgeted this year.” Our family budget guide covers this.
What if 13th month does not come?
If it is discretionary, there may be nothing to claim. If it is in your contract and not paid, write to HR asking politely when it will be paid, quoting the clause. Keep copies. If it becomes a dispute, consult a labour lawyer or your union. Either way, do not spend a bonus before it lands in your account.
Negotiating bonuses
When you receive a job offer, ask whether the annual package includes a 13th month, what the bonus policy is, and whether bonuses have actually been paid in recent years. A higher fixed monthly salary is usually more reliable than a promised bonus. Our salary negotiation guide covers how to compare offers.
For planning the year around expected bonuses and big expenses, the 2027 Printable Planner has monthly pages where you can mark pay dates and due dates.
Checklist before the money arrives
- Confirm with HR whether the payment is contractual or discretionary, and the expected date.
- Estimate the after-tax amount using your marginal PAYE rate.
- Write your split: January buffer, debt, emergency fund, planned costs, enjoyment.
- Set up the transfers so they can go out the same day the money lands.
Frequently asked questions
Is 13th-month salary compulsory in Nigeria?
We are not aware of a general legal requirement for private employers. It depends on your contract, handbook, any collective agreement, and possibly established practice.
Is 13th month taxed?
Generally yes. It forms part of employment income and is taxed at your marginal PAYE rate.
Why was so much tax taken from my bonus?
Monthly payroll calculations can over-deduct in a bonus month. Ask payroll whether PAYE will be reconciled over the year.
I resigned in October. Do I get a pro-rated 13th month?
Only if your contract or company policy provides for pro-rating. Check the clause and ask HR in writing.
Should I use my bonus to invest?
Only after expensive debt is cleared and you have an emergency fund. Then you can consider longer-term options.
