Here’s the short answer: there is no special “bonus tax” in Singapore. Your bonus — whether it’s your AWS (the 13th-month payment), a performance bonus, or a variable bonus — is simply employment income. It gets added to your annual total and taxed at your marginal rate, in the year you’re entitled to it (usually the year it’s paid). Because Singapore uses progressive tax rates, a big bonus is taxed at your top band — but only the slice that crosses into a higher band, so a bonus never leaves you worse off overall.
💡 Why there’s no separate “bonus tax”
Many people assume a bonus is taxed differently, or more harshly, than their monthly salary. It isn’t. The Inland Revenue Authority of Singapore doesn’t have a “bonus tax” category. Your bonus is just income, exactly like your salary.
That means it’s lumped together with your wages, your director’s fees, and any other employment income for the year. The total becomes part of your chargeable income, and the same progressive resident rates — from 0% up to 24% for YA2026 — apply to the whole amount. You can sanity-check the full picture with our Income Tax calculator.
📈 How progressive rates treat your bonus
Singapore’s income tax is tiered. The first chunk of your income is taxed at a low rate, and each higher band is taxed at a higher rate. Crucially, only the income that falls within a band is taxed at that band’s rate — not your entire income.
So when a bonus pushes some of your income into a higher band, only that portion is taxed at the higher rate. The rest of your income stays exactly where it was. This is why a bonus can never make you worse off: you always keep more money after receiving it, even if the top slice is taxed more heavily.
- Your salary fills up the lower bands first.
- Your bonus sits “on top”, taxed at whatever band it lands in.
- Only the amount crossing into a higher band pays the higher rate.
🧮 A worked example
Say your annual salary gives you a chargeable income of $80,000, and you receive a $20,000 bonus. That bonus is added on top, so your chargeable income becomes $100,000.
The bonus doesn’t get its own special rate. Instead, it’s taxed at the marginal bands it occupies — in this case, the bands that apply to income between $80,000 and $100,000. The first $80,000 of your income is taxed exactly as it would have been without the bonus. Only the extra $20,000 is taxed at your higher marginal band.
In other words, the tax on your bonus is just the difference between the tax on $100,000 and the tax on $80,000. To see the exact dollar figure for your own numbers, pop them into the bonus tax calculator, which works out the marginal tax on your bonus for you.
⏱️ You’re not taxed when the bonus is paid
Unlike some countries, Singapore residents don’t have tax withheld at the moment a bonus hits your bank account. There’s no PAYE-style deduction taken off the top. You receive the full bonus, and the tax is settled later, when IRAS assesses your income for the year.
A bonus is taxed in the year you become entitled to it — for a discretionary bonus that’s usually the year it’s paid, while a contractual bonus follows your contract terms. Either way, because nothing is withheld upfront, it’s wise to set aside part of your bonus for the eventual tax bill rather than spending it all. Working out your actual monthly cash position is easier with our take-home pay calculator.
✅ Things worth remembering
- There is no separate bonus tax — your bonus is ordinary employment income.
- It’s added to your annual income and taxed at your marginal rate.
- Only the portion crossing into a higher band is taxed at that higher rate.
- A bonus never reduces your take-home pay overall.
- Residents have no tax withheld at payment; you pay when assessed.
🔎 Run your own numbers
The cleanest way to stop worrying about your bonus is to see the real figure. Drop your salary and bonus into the bonus tax calculator to see exactly how much tax the bonus adds, then cross-check the full year with the Income Tax calculator. You’ll quickly see the “bonus tax” fear was never something to lose sleep over.
