你是否曾疑惑，為何香港有些高收入人士繳交的稅款出奇地低，而部分收入一般的人士稅單卻較高？答案在於香港獨特的「兩者取其低」稅制。無論你是剛畢業的職場新鮮人、資深專業人士，還是擁有多元收入來源的人，了解這套系統如何運作，每年或可為你節省數以萬計的金錢。讓我們深入剖析香港的稅階，揭示你實際需要繳付的稅款。
香港獨特的「兩者取其低」薪俸稅制
香港的薪俸稅制度在全球獨樹一幟，其精妙之處在於「繳付較低稅款」的原則。與大多數國家將納稅人劃入單一稅階不同，香港稅務局會自動以兩種不同方式計算你的稅款，而你只需繳付金額較低的一項。這形成了一個內置的安全網，既能防止過度徵稅，亦能在不同收入水平間維持公平性。
累進稅率制度
累進稅率制度會對你的「應課稅入息實額」（即扣除免稅額及可扣除項目後的入息）的不同部分，應用遞增的稅率。2024/25課稅年度的累進稅率如下：
| 應課稅入息實額級別（港元） | 稅率 | 該級別稅款 |
|---|---|---|
| 首 50,000 | 2% | 1,000 |
| 次 50,000 | 6% | 3,000 |
| 再次 50,000 | 10% | 5,000 |
| 再次 50,000 | 14% | 7,000 |
| 其餘餘額 | 17% | 餘額的 17% |
標準稅率制度
由2024/25課稅年度起，香港引入了兩級制標準稅率：
| 入息水平 | 標準稅率 | 應用範圍 |
|---|---|---|
| 首 500 萬港元 | 15% | 按應課稅入息計算 |
| 超過 500 萬港元的部分 | 16% | 僅按超出部分計算 |
最大化你的稅務節省：善用免稅額及扣除項目
你的稅務責任不僅取決於薪金，更取決於在應用各種免稅額和扣除項目後剩下的金額。香港提供豐厚的免稅額，能顯著降低你的應課稅入息。以下是2024/25課稅年度你需要知道的資訊：

實例計算：看清「兩者取其低」如何運作
讓我們透過一個實際例子，看看香港的雙軌制稅制如何運作。假設一名單身人士在2024/25課稅年度的年薪為800,000港元：
- 步驟一：計算應課稅入息
薪金：800,000港元
減去強積金供款：18,000港元
應課稅入息：782,000港元 - 步驟二：計算應課稅入息實額
應課稅入息：782,000港元
減去基本免稅額：132,000港元
應課稅入息實額：650,000港元 - 步驟三：累進稅率計算
首50,000港元按2%：1,000港元
次50,000港元按6%：3,000港元
再次50,000港元按10%：5,000港元
再次50,000港元按14%：7,000港元
其餘450,000港元按17%：76,500港元
累進稅款總額：92,500港元 - 步驟四：標準稅率計算
應課稅入息：782,000港元
標準稅率（首500萬港元適用15%）：15%
標準稅率稅款：117,300港元 - 步驟五：繳付較低稅款
累進稅款：92,500港元
標準稅率稅款：117,300港元
應繳稅款：92,500港元（較低的一項）
物業稅 vs 薪俸稅：何時選用「個人入息課稅」
如果你在香港擁有物業並收取租金收入，你將需要繳交劃一15%稅率的物業稅。然而，你可以透過選擇「個人入息課稅」來降低整體稅務負擔。以下是兩種稅制的比較：
| 稅項類別 | 稅率結構 | 評稅基礎 | 主要特點 |
|---|---|---|---|
| 薪俸稅 | 累進稅率（2%-17%）或標準稅率（15%-16%） | Employment income, pension | "Whichever is lower" calculation |
| Property taxes | Flat 15% | Net rental income from the property | enjoys 20% statutory tax exemption (for repairs and expenses) |
When can Personal Assessment save you money?
Personal Assessment allows you to combine income from different sources (salary, rent, business profits) and assess them together at progressive salaries tax rates. It may be beneficial to you if:
- The marginal salaries tax rate applicable to your total income is less than 15%.
- You have significant deductions/exemptions that exceed the amount you can claim under property tax.
- You want to avoid double taxation on rental income.
Tax strategies planned by life stage
Your tax planning strategy should adapt to your life stages. Here's how to optimize your tax situation at different stages:
Young professionals (early career)
