Why employer-paid tax creates more taxable income
Tax paid by an employer for its employee is an employment benefit, described here as a tax allowance. It therefore increases the employee’s income and can itself create further tax. The PDF works through full tax coverage, two partial-coverage agreements, multiple employers, personal rebates and changes in marginal rates. Most examples concern income earned in 2021 and YA 2022; the rebate examples concern YA 2017 and YA 2019. They must retain their own year’s rate and rebate assumptions, even though the reference table also includes YA 2024 onward rates.
Start with notional tax, then gross up the employer’s share
First calculate income and personal reliefs before adding the tax allowance, producing notional chargeable income and notional tax. If the marginal rate r remains unchanged, additional tax-on-tax is the employer’s notional tax share multiplied by r/(1−r); total allowance is that share plus the additional tax. For partial coverage of specified income, use notional tax multiplied by the covered income divided by total income on the aggregate basis. For an agreement requiring the employee to pay a fixed tax amount, subtract that amount from notional tax before grossing up the employer’s remainder. Finally add the allowance to income, deduct reliefs and recalculate total tax. Do not use the simple single-rate formula when the allowance crosses a bracket or an uncapped rebate changes the effective marginal rate.
Example 1: full employer coverage
For YA 2022 salary S$50,000, no other income and reliefs S$7,000, notional chargeable income is S$43,000. Tax is S$550 on the first S$40,000 plus S$210 at 7%, giving S$760. Tax-on-tax is S$760×0.07/0.93=S$57.20, so allowance is S$817.20. Final income S$50,817.20 less reliefs gives chargeable income S$43,817.20 and final tax S$817.20, wholly paid by the employer.
Example 2(a): tax on a specified allowance
For YA 2022 salary S$130,000 plus covered allowance S$20,000, total S$150,000 less reliefs S$7,000 gives S$143,000. Notional tax is S$7,950 plus S$23,000×15%=S$11,400. Employer’s share is S$11,400×20,000/150,000=S$1,520, rather than taxing the S$20,000 in isolation. Tax-on-tax S$268.24 produces allowance S$1,788.24. Final chargeable income S$144,788.24 gives tax S$11,668.24: employer S$1,788.24, employee S$9,880.
Example 2(b): employee pays a fixed tax amount
With YA 2022 salary S$150,000 and reliefs S$7,000, notional tax is again S$11,400. The agreement makes the employee responsible for S$3,000, leaving employer notional tax S$8,400. Grossing at 15% adds S$1,482.35, creating allowance S$9,882.35. Final chargeable income is S$152,882.35 and tax S$12,882.35, split employee S$3,000 and employer S$9,882.35. This agreement differs from specifying an income amount whose tax is covered.
Examples 3(a) and 3(b): more than one employer
In 3(a), YA 2022 earnings are A’s S$50,000 and B’s S$120,000, with S$7,000 reliefs and only A covering its income tax. Notional chargeable income S$163,000 gives tax S$14,490. A’s share S$14,490×50,000/170,000=S$4,261.76; 18% gross-up adds S$935.51, giving A allowance S$5,197.27. Final tax S$15,425.51 leaves employee S$10,228.24. In 3(b), A pays S$50,000 and covers it, while B pays salary S$40,000 plus covered allowance S$10,000. Notional chargeable income S$93,000 gives S$4,845 tax. A’s S$2,422.50 share grossed at 11.5% becomes S$2,737.29; B’s S$484.50 becomes S$547.46. Total allowance S$3,284.75 gives final tax S$5,222.75, employee S$1,938. Both examples aggregate all employment income before allocating employer shares.
Example 4(a): a rebate already at its cap
For YA 2019 salary S$50,000, reliefs S$7,000 and notional tax S$760, the historical 50% personal rebate is already capped at S$200, leaving S$560. The rebate cannot increase with the added allowance, so the ordinary 7% formula applies: additional tax S$42.15, allowance S$602.15. Final pre-rebate tax S$802.15 less the same S$200 produces S$602.15 fully borne by the employer. The 50%/S$200 rebate belongs to the YA 2019 example, not every assessment year.
Example 4(b): an uncapped percentage rebate
For YA 2017 with the same salary and reliefs, the source’s 20% rebate capped at S$500 reduces notional S$760 by S$152 to S$608. As the rebate is still below its cap, the effective marginal rate is 7%×(1−20%)=5.6%. Tax-on-tax is S$608×0.056/(1−0.056)=S$36.07, giving allowance S$644.07. The final computation rounds gross tax S$805.08 and rebate S$161.02 to produce S$644.06. The source consequently has a one-cent allowance/final-tax difference; retain the displayed rounded figures rather than silently asserting exact equality. Reassess the formula if a gross-up causes the rebate cap to be reached.
Example 5(a)(i): full coverage crosses from 20% to 22%
YA 2022 salary S$300,000 less S$7,000 reliefs gives S$293,000 and notional tax S$39,150. There is S$27,000 of room to S$320,000. Of the initial notional-tax addition, S$27,000 creates tax at 20%, S$5,400, and S$12,150 creates tax at 22%, S$2,673. Their S$8,073 further tax is then grossed up at 22%, adding S$2,277. Total allowance S$39,150+8,073+2,277=S$49,500. Final chargeable income S$342,500 gives S$44,550 plus S$22,500×22%=S$49,500. A single 20% calculation would fail to account for the upper bracket.
Example 5(a)(ii): covered bonus crosses from 19.5% to 20%
For salary S$200,000, employer-covered bonus S$77,000 and reliefs S$7,000 in YA 2022, notional income S$270,000 gives tax S$34,600. The covered share is S$34,600×77,000/277,000=S$9,618.05. Initial tax at 19.5% is S$1,875.52, but only S$381.95 remains before the S$280,000 boundary after adding the covered share. Tax on that remainder is S$74.48; the remaining S$1,492.57 incurs S$298.51 at 20%, for S$372.99, then further gross-up about S$93.25. Together these reconcile to the source’s final allowance S$11,960.06, final chargeable income S$281,960.06, tax S$36,942.01 and employee S$24,981.95. The PDF’s intermediate main-table line prints S$1,493.57, S$298.71 and S$373.19, while its own workings give S$1,492.57. Those intermediate lines do not reconcile; the corrected arithmetic above is explicitly identified rather than reproducing the inconsistency as a valid formula.
Example 5(b): two successive bracket changes
YA 2022 salary S$290,000 less S$11,000 reliefs gives notional income S$279,000 and tax S$36,355. Only S$1,000 remains at 19.5%, followed by S$40,000 at 20%, then 22%. To fill the first gap, a S$805 underlying amount grossed at 19.5% adds S$195, total S$1,000. For the next bracket, S$32,000 grossed at 20% adds S$8,000, total S$40,000. The remaining notional-tax portion S$36,355−805−32,000=S$3,550 adds S$1,001.28 at 22%. Total allowance is S$45,551.28. Final chargeable income S$324,551.28 produces S$44,550 plus S$1,001.28, confirming the same total tax wholly borne by the employer.
Rate tables and non-resident employment income
The reference resident schedule is progressive, not a flat rate on all income. YA 2017–2023 uses the same bands up to S$320,000 as the later table but taxes all excess at 22%. From YA 2024 the 22% band ends at S$500,000, then 23% applies to the next S$500,000 and 24% above S$1 million. The source states that non-resident employment income is taxed at flat 15% or progressive resident rates, whichever gives the higher tax. It does not extend that employment rule to every non-resident income category.
| YA 2024 onward income band (S$) | Marginal rate | Cumulative tax (S$) |
|---|---|---|
| 0–20,000 | 0% | 0 |
| 20,000–30,000 | 2% | 200 at 30,000 |
| 30,000–40,000 | 3.5% | 550 at 40,000 |
| 40,000–80,000 | 7% | 3,350 at 80,000 |
| 80,000–120,000 | 11.5% | 7,950 at 120,000 |
| 120,000–160,000 | 15% | 13,950 at 160,000 |
| 160,000–200,000 | 18% | 21,150 at 200,000 |
| 200,000–240,000 | 19% | 28,750 at 240,000 |
| 240,000–280,000 | 19.5% | 36,550 at 280,000 |
| 280,000–320,000 | 20% | 44,550 at 320,000 |
| 320,000–500,000 | 22% | 84,150 at 500,000 |
| 500,000–1,000,000 | 23% | 199,150 at 1,000,000 |
| Above 1,000,000 | 24% | 199,150 + 24% of excess |
