Your Bonus Breakdown
Understanding Bonus CPF & Tax for Singapore Employees
Every Singapore employee who receives a year-end bonus, 13th-month AWS, or performance bonus faces the same question: how much will I actually take home? The answer depends on two deductions: CPF contributions governed by the Additional Wage (AW) Ceiling, and marginal income tax assessed by IRAS under the progressive resident tax framework. As at Q1 2026, employees aged 55 and below contribute 20% of their bonus to CPF (up to the AW ceiling), while employers contribute 17%. On top of this, the bonus is taxed at your marginal rate — which can range from 0% for lower-income earners to 22% for those with chargeable income above S$320,000. This calculator helps you see both deductions at once, so you know exactly what to expect in December or March when your bonus hits.
Not financial advice. All figures are estimates for educational reference. CPF rates and tax brackets are per CPF Board and IRAS as at Q1 2026 — confirm with your employer or tax advisor for your specific situation.
What Is the Additional Wage (AW) Ceiling?
The Additional Wage Ceiling caps how much of your bonus is subject to CPF contributions. The formula is simple: AW Ceiling = S$102,000 minus your total Ordinary Wages (OW) already subject to CPF that year. If you earn S$5,000/month for 12 months, your OW is S$60,000, so your AW ceiling is S$42,000. Any bonus amount below S$42,000 attracts full CPF contributions at your age-tiered rate. Bonus above the AW ceiling is CPF-exempt — but it remains fully taxable as income. This ceiling was established by the CPF Board to prevent employers from reclassifying salary as bonuses to reduce CPF obligations.
How Bonuses Are Taxed in Singapore
Bonuses are added to your total employment income and taxed under IRAS’s progressive resident rates for Year of Assessment 2026. A contractual bonus (such as a 13th-month AWS) earned in 2025 and paid in early 2026 is taxable in YA2026. The key concept is marginal taxation: only the income in each bracket is taxed at that bracket’s rate. For a median Singapore employee earning S$5,000/month with a S$10,000 bonus, the effective tax on the bonus alone is typically 7–12% — far below the headline top rate of 22%. Using the SRS scheme, CPF top-ups, and other reliefs can reduce chargeable income and lower the tax bite on your bonus.
How to Use This Bonus Tax & CPF Calculator
- Enter your monthly salary: Input your gross monthly Ordinary Wages (before CPF deduction). This determines how much OW has already been subject to CPF, which sets your AW ceiling.
- Enter your bonus amount: Key in the gross bonus figure you expect to receive — this could be AWS, performance bonus, or any Additional Wage payment.
- Set your age: Use the slider to select your age. CPF contribution rates drop significantly after 55, 60, and 65, so age makes a major difference to how much CPF is deducted from your bonus.
- Adjust months worked: If you joined mid-year or took unpaid leave, reduce the months slider. Fewer OW months means a higher AW ceiling, potentially making more of your bonus subject to CPF.
- Add reliefs: Enter your estimated personal tax reliefs (e.g. CPF cash top-up relief, SRS contribution, earned income relief). This reduces your chargeable income and lowers the tax on your bonus.
The calculator instantly shows your AW ceiling, CPF deducted, marginal tax on the bonus, and net take-home cash. Results update in real time as you adjust inputs.
Pro tip: Combine this with our SRS Tax Savings Calculator — contributing to SRS before year-end can meaningfully reduce the tax bite on your bonus.
What Is the Additional Wage Ceiling?
The Additional Wage (AW) Ceiling is the CPF Board’s mechanism for capping CPF contributions on variable pay. For 2026, the formula remains: AW Ceiling = S$102,000 − Total Ordinary Wages subject to CPF in the same calendar year. Ordinary Wages (OW) are your regular monthly salary payments, capped per month at S$6,800 (2026 Ordinary Wage ceiling). Additional Wages include bonuses, commissions, overtime pay, and any variable pay that is not part of your fixed monthly salary.
For a full-year employee earning S$5,000/month, total OW is S$60,000 and the AW ceiling is S$42,000. Any bonus up to S$42,000 attracts full CPF at age-tiered rates. Above S$42,000, the excess is not subject to CPF — you keep that portion as cash. The ceiling prevents high-earning employees from having CPF deducted on very large bonuses beyond what is already a generous S$102,000 annual cap. For comparison, an employee earning S$8,500/month (above the OW ceiling) would have OW CPF contributions capped at S$6,800 × 12 = S$81,600, leaving only a S$20,400 AW ceiling.
| Monthly Salary | Annual OW (CPF) | AW Ceiling |
|---|---|---|
| S$3,000 | S$36,000 | S$66,000 |
| S$5,000 | S$60,000 | S$42,000 |
| S$7,000 | S$81,600* | S$20,400 |
| S$8,500+ | S$81,600* | S$20,400 |

How CPF Is Calculated on Your Bonus
Once you know your AW ceiling, CPF on your bonus is straightforward: multiply the lower of (bonus amount, AW ceiling) by your contribution rate. The rates vary by age and are split between employee and employer contributions. For employees aged 55 and below in 2026, the total CPF contribution rate is 37% (employee 20%, employer 17%). The employee portion is deducted from your bonus payout; the employer portion is an additional cost to your employer that goes into your CPF account — it does not reduce your cash bonus.
| Age Band | Employee Rate | Employer Rate | Total |
|---|---|---|---|
| ≤55 | 20% | 17% | 37% |
| 56–60 | 15% | 15.5% | 30.5% |
| 61–65 | 10.5% | 10.5% | 21% |
| 66–70 | 7.5% | 7.5% | 15% |
| Above 70 | 5% | 5% | 10% |
For a Singapore Citizen or PR aged 30 receiving a S$10,000 bonus with a S$42,000 AW ceiling, employee CPF is S$2,000 and employer CPF is S$1,700. The employee’s gross bonus is S$10,000 but S$2,000 goes to CPF before cash hits the bank. That S$2,000 is not lost — it goes into your Ordinary Account and earns at least 2.5% p.a. tax-free, contributing to your CPF Retirement Sum.
How Income Tax Applies to Your Bonus
Your bonus is added to total employment income and assessed under IRAS’s progressive resident tax rates for Year of Assessment (YA) 2026. Singapore’s tax framework is highly favorable by global standards — the first S$20,000 of chargeable income is tax-free, and rates only reach double digits at S$80,000. For most Singapore employees, the effective marginal tax rate on a moderate bonus is 7–15%.
The critical concept is that bonuses are taxed at your marginal rate — the rate applicable to the band your total chargeable income falls into. A S$10,000 bonus for someone whose chargeable income is S$60,000–70,000 is taxed at 7%. The same bonus for someone at S$200,000–210,000 is taxed at 19%. This is why high earners feel a bigger tax pinch on their bonuses. Chargeable income = gross income minus CPF contributions (employee share) minus all eligible reliefs. The IRAS allows reliefs such as the earned income relief, CPF cash top-up relief, SRS contribution relief, NSman relief, and parent/handicapped sibling relief, among others. Maximising reliefs before 31 December can meaningfully reduce your bonus tax.
How to Reduce Tax on Your Bonus in Singapore
Singapore offers several legitimate levers to reduce the income tax on your bonus — all within IRAS rules. The most effective for working professionals are CPF and SRS top-ups. A voluntary CPF Cash Top-Up to your Special Account (before age 55) or Retirement Account (after 55) gives you dollar-for-dollar tax relief up to S$8,000 per year for yourself (plus another S$8,000 for topping up a family member’s account). See our CPF Cash Top-Up Tax Relief Calculator for the exact savings. Separately, contributing to the Supplementary Retirement Scheme (SRS) gives relief up to S$15,300/year for Singapore Citizens and PRs. Both strategies work particularly well in bonus years when you suddenly face a higher marginal rate.
Other useful reliefs include course fee relief (up to S$5,500/year for approved courses), parent relief (up to S$9,000/parent), and NSman self relief (S$3,000 in active-service years). For high earners, making charitable cash donations via IRAS-registered charities gives a 2.5× tax deduction under the Institutions of Public Character (IPC) scheme. The net effect: a well-planned Singapore employee earning S$80,000 with a S$15,000 bonus can often reduce their effective tax on the bonus to under 5% through a combination of CPF and SRS contributions. Use our SRS Tax Savings Calculator and Singapore Income Tax Calculator together for a full picture.
Bonus Season in Singapore: Benchmarks & Norms
Singapore operates two main bonus conventions: the Annual Wage Supplement (AWS) — colloquially the “13th month bonus” — and performance-based variable bonuses. The AWS is a contractual payment equivalent to one month’s salary, paid in the fourth quarter, typically November to January. It is not legally mandated but is included in most Singapore employment contracts and is highly normalised across sectors. According to the Ministry of Manpower (MOM) 2025 data, approximately 60% of employees in Singapore are covered by AWS provisions.
Performance bonuses vary widely by industry. Financial services, technology, and consulting regularly pay 2–6 months of bonus at senior levels. Public service employees receive variable payments linked to Singapore’s GDP growth. In a strong growth year, civil servants may receive a mid-year and year-end variable component together exceeding 2.5 months. For 2025 (payable in early 2026), MOM data showed median variable bonus for professionals and managers at approximately 1.5–2 months of salary.

How to Invest Your Bonus for Passive Income
A S$10,000–S$30,000 year-end bonus represents a significant lump sum for most Singapore investors. Rather than letting it sit in a savings account, deploying it into income-generating assets can accelerate your retirement timeline. The three most popular strategies among Singapore retail investors are: (1) deploying into S-REITs for 5–7% dividend yields, (2) investing via Endowus or Syfe into globally diversified portfolios using cash or SRS funds, and (3) using the bonus for a CPF top-up to maximise tax relief and compound interest.
For S-REIT exposure, platforms like Syfe (use referral code SRPRFFFCD for a fee waiver) offer managed REIT+ portfolios with quarterly distributions and lower single-stock risk. Alternatively, Endowus (use referral code 2V343) provides access to institutional-grade funds with CPF and SRS compatibility. For direct stock-picking, FSMOne charges some of the lowest commissions in Singapore at 0.08% for SGX trades. Whichever route you take, our Dividend Portfolio Yield Calculator can help you model the passive income from your bonus investment.

Frequently Asked Questions
Is my bonus subject to CPF in Singapore?
Yes, bonuses (called Additional Wages) are subject to CPF contributions in Singapore, but only up to the Additional Wage Ceiling. The AW Ceiling = S$102,000 minus your total Ordinary Wages subject to CPF that year. For most full-year employees earning S$5,000/month, this means bonuses up to S$42,000 attract CPF at age-tiered rates. Any bonus amount above the AW ceiling is CPF-exempt but remains fully taxable as income.
How much CPF is deducted from a bonus for someone aged 30 in Singapore?
For an employee aged 55 or below, the employee CPF rate is 20% on the portion of the bonus within the AW ceiling. So a S$10,000 bonus for a 30-year-old earning S$5,000/month would result in S$2,000 of employee CPF deducted (20% × S$10,000, since the full bonus is below the S$42,000 AW ceiling). The employer also contributes S$1,700 (17% × S$10,000) on top — this does not reduce your cash payout but goes into your CPF account.
What is the Additional Wage Ceiling for 2026?
The 2026 Additional Wage Ceiling is S$102,000 minus your total Ordinary Wages subject to CPF for that calendar year. The S$102,000 figure has remained unchanged since 2016. If you earned S$5,000/month for 12 months, your AW ceiling is S$42,000. If you earned a higher salary of S$8,500+/month, your OW CPF is capped at S$6,800/month (S$81,600/year from Jan 2026), leaving an AW ceiling of S$20,400.
Do I pay income tax on my bonus in Singapore?
Yes. Your bonus is added to your total employment income and taxed at IRAS’s progressive resident rates under Year of Assessment 2026. The effective tax depends on your total chargeable income (gross income minus CPF employee contributions minus reliefs). For a median Singapore employee, the marginal tax rate on a moderate bonus is typically 7–12%. Singapore’s rates are low by global standards — there is no separate bonus tax rate; it simply falls into your income bracket.
When is my bonus taxable — when earned or when paid?
Under IRAS rules, employment bonuses are taxed in the Year of Assessment relating to when they are paid (or when you are entitled to receive them, whichever is earlier). A contractual AWS earned for calendar year 2025 but paid in January 2026 is typically assessed in YA2026 (for income earned in 2025, assessed in 2026). Non-contractual discretionary bonuses follow the same rule: taxed in the YA corresponding to when they are paid.
How can I reduce tax on my bonus in Singapore?
The most effective strategies are CPF Retirement Sum Top-Up (up to S$8,000 relief for self, another S$8,000 for family member top-ups) and SRS contribution (up to S$15,300/year for Citizens/PRs). Both are deducted from chargeable income before tax is computed. Making these contributions before 31 December each year is important — they must be completed within the calendar year to count against that year’s income. Use our SRS Tax Savings Calculator to model the exact relief.
Is the 13th month AWS subject to CPF and tax?
Yes. The Annual Wage Supplement (AWS) is an Additional Wage and is treated exactly the same as any other bonus for both CPF and tax purposes. It is subject to CPF contributions up to the AW ceiling, and is added to employment income for IRAS tax assessment. There is no special exemption for the 13th month — it is simply labelled differently but treated identically to a performance bonus under CPF and IRAS rules.
What happens if my bonus exceeds the AW ceiling?
The portion of your bonus above the AW ceiling is not subject to CPF contributions — neither from you nor your employer. However, that excess bonus is still fully taxable as employment income under IRAS. For example, if your AW ceiling is S$42,000 and you receive a S$60,000 bonus, CPF applies only to the first S$42,000 (employee: S$8,400, employer: S$7,140). The remaining S$18,000 has no CPF deducted — but all S$60,000 is included in your income for tax purposes.
Can I invest my bonus via CPF or SRS in Singapore?
You cannot direct your bonus payment into CPF automatically (your employer handles CPF deductions at the standard rate), but you can make voluntary top-ups from your cash bonus to your CPF Special Account (below age 55) or Retirement Account (above age 55) — and claim up to S$8,000 in tax relief for doing so. Separately, you can transfer your net cash bonus to your SRS account (at DBS, OCBC, or UOB) and invest it in unit trusts, Singapore equities, or ETFs — while claiming up to S$15,300 SRS contribution relief. See our CPF Cash Top-Up Tax Relief Calculator and SRS Withdrawal Tax Calculator for the long-term numbers.
