中国工资个税与到手(累计预扣)
用真实的累计预扣预缴法计算中国工资的每月和全年个人所得税(IIT)。由于税是按年初至今的收入重新计算的,同样的税前工资随着累计收入爬升税档,每月被预扣得越来越多——所以你的到手工资会在一年中逐月下降。简单的按月分档计算器(以及通用 AI)会把跨过第一个税档之后的每个月都算错。

老手的解读
值得了解
Same 30,000 gross every month, but tax withheld rises from 525 in month 1 to 3,500 in month 12 — so take-home drops about 2,975 between January and December, with the first jump in month 3. This is the cumulative method: it is deferral, not extra tax — the year totals the same either way, but a flat monthly-bracket calculator shows the wrong number for most of the year.
值得了解
Your 3,000/month of special additional deductions cut tax, not take-home cash directly — they lower taxable income, saving roughly 7,200 a year at your marginal rate. Make sure you have claimed every one you qualify for.
值得了解
An annual bonus (全年一次性奖金) can be taxed separately (bonus ÷ 12 to find the rate) or rolled into annual income — the cheaper choice differs by income, and there are “trap” amounts just above each threshold where a slightly bigger bonus nets you less. The separate option is available through end-2027.
方法说明
累计预扣预缴法:每月的税按年初至今应税所得计算 = 累计税前 − 累计(每月 5,000 元基本减除 + 社保 + 专项附加扣除),套用全年综合所得税率表;当月预扣 = 该累计税额减去本年已预扣的税。
由于累计收入随年份推进爬入更高税档,即便税前恒定,每月预扣额也会上升(到手下降)。这是递延,不是多缴税——12 个月之和等于按税率表对全年应税所得计算的税。
全年综合所得税率表(累计):3% 至 36,000;10% 至 144,000(−2,520);20% 至 300,000(−16,920);25% 至 420,000(−31,920);30% 至 660,000(−52,920);35% 至 960,000(−85,920);45% 以上(−181,920)。
专项附加扣除减少应税所得(从而减税),而非减少到手现金。本工具假设每月税前恒定、每月扣除相同;不规律的发薪或年中变动会改变逐月的分布,但不改变全年总额。
常见问题
- 为什么我在中国的到手工资到年底会变少?
- 因为个税是按累计法预扣的:税每月按你年初至今的收入重新计算。随着累计收入跨入更高税档,每月预扣上升,所以即便税前不变到手也在下降。它会拉平——全年总额相同——但每月金额并不均等。
- 中国工资的个人所得税怎么算?
- 每月应税所得 = 税前 − 5,000 元基本减除 − 你的社保 − 专项附加扣除。税按全年综合所得税率表,作用于累计的年初至今应税所得,每月预扣的是相对已预扣部分的增加额。
- 专项附加扣除有哪些?
- 子女教育(每个子女每月 2,000)、3 岁以下婴幼儿照护(每个子女 2,000)、赡养老人(最多每月 3,000)、首套住房贷款利息(每月 1,000)或住房租金(按城市每月 800–1,500),以及继续教育(每月 400)。它们降低应税所得;大病医疗在年度汇算时申报。
