Your year-end bonus in Shanghai can be taxed one of two ways: on its own using a preferential monthly-rate method, or rolled into your annual income, and until December 31.
Your year-end bonus in Shanghai can be taxed one of two ways: on its own, using a preferential method that divides the bonus by twelve to find a gentler rate, or rolled into your annual income. Until December 31, 2027 you pick whichever leaves you more. For most people with one bonus the separate method wins, but one bracket trap can cost you thousands.
It does not always win, though. Here is how year-end money works when you are employed in Shanghai, how the two tax methods actually compare, which one to choose, and the cliff that catches people who never run the numbers.
Good to know
- Good for: anyone employed in Shanghai who gets a 13th-month salary or a year-end bonus and wants to keep more of it.
- What you'll pay: tax from 3 to 45 percent of the bonus depending on size and method; the separate method usually lands far lower.
- Make the most of it: run both methods before you accept a bonus figure, and mind the bracket cliffs explained below.
What counts as year-end money in Shanghai?
Year-end money in a Shanghai job usually means one of two things, and they are not the same. A 13th-month salary (十三薪) is a contractual extra month written into your offer, so it is money you are owed. A year-end bonus (年终奖) is usually discretionary, tied to company and personal performance, and can be zero in a bad year. Some contracts pay both. For tax, what matters is that a lump-sum annual bonus can use the preferential 全年一次性奖金 method, and you may use that method for only one such lump sum per year.
If your bonus is paid in the first quarter of 2027 for the 2026 year, that is normal. Chinese companies commonly pay year-end bonuses just before Spring Festival, so a "2026 bonus" often lands in January or February. It is taxed in the month it is paid.
How is a year-end bonus taxed?
A resident year-end bonus in China can, for now, be taxed by one of two methods. The separate method (单独计税) takes the bonus out of your annual income, divides it by twelve to find the monthly-equivalent tax rate, then applies that rate to the whole bonus with one quick deduction. The combined method (并入综合所得) simply adds the bonus to your yearly salary and taxes the total on the normal annual scale, the one explained in our guide to Shanghai individual income tax rates and the 6-year rule. Most full-year employees in Shanghai are tax residents, so both methods are open to you, and you choose at the annual reconciliation (汇算) the following spring.
The separate method usually wins because dividing by twelve drops the bonus into a lower rate band than your salary sits in. But if your regular salary is low, or your deductions are large enough that your taxable salary is small, folding the bonus into your annual income can be taxed even more gently. The rule of thumb: high earners with a big salary almost always take the separate method; anyone closer to the salary you need to live well in Shanghai should run both.
Separate or combined: which method wins?
Which method wins for a Shanghai bonus depends on the size of the bonus against the size of the salary, so calculate both before you file. One thing is settled: have payroll declare the bonus under the separate 全年一次性奖金 heading at withholding, because the spring reconciliation lets you merge a separately declared bonus into annual income later, while a bonus withheld as ordinary salary cannot be reclassified as separate.
A worked case makes the choice concrete. Take a Shanghai salary of 30,000 yuan a month (about USD 4,478) and a 100,000-yuan (USD 14,925) bonus. Under the separate method the bonus is taxed on its own at 10 percent, 9,790 yuan (USD 1,461). Under the combined method it stacks on top of your roughly 300,000-yuan taxable salary and is taxed at 25 percent, so the same bonus costs about 15,000 yuan (USD 2,239) more. That gap is exactly why most salaried earners keep the bonus separate, and why the one group that does not is people whose taxable salary is small enough to still sit in a low band after the bonus is folded in.
The bracket cliff that quietly eats your bonus
The separate method has a notorious trap, and it is the single most useful thing to know before you sign off on a bonus figure. Because the rate is set by the bonus divided by twelve, there are points where one extra yuan pushes the whole bonus into a higher rate, so you take home less by earning more. The first and most common cliff sits right at 36,000 yuan (USD 5,373).
A bonus of exactly that size divides to 3,000 a month, taxed at 3 percent, so you keep 34,920 (USD 5,212). Add a single yuan and it tips into the 10 percent band, and you keep only 32,611 (USD 4,868). That one extra yuan of bonus has cost you roughly 2,310 yuan (about USD 344) in take-home pay. The same drop sits just above five more points, at 144,000 (USD 21,493), 300,000 (USD 44,812), 420,000 (USD 62,651), 660,000 (USD 98,543) and 960,000 yuan (USD 143,248). If your bonus lands a hair over any of them, ask payroll whether it can be set just under, or move the excess into next month's salary.
What actually lands in your account?
Here is what a Shanghai year-end bonus actually delivers under the separate method, three sizes worked end to end so you can sanity-check your own payslip. Numbers are rounded and use a rate of about 6.7 yuan to the US dollar, mid-2026; treat the dollar figures as a ballpark.
Read down the keep column as a share of each bonus and the pattern shows: 97 percent, then 90, then 81. The slide is gradual rather than brutal, which is why high earners rarely fold a bonus into annual income.
One more thing expats forget
Foreign nationals in Shanghai who still use the tax-free benefit-in-kind allowances (housing, children's schooling, language training) are on a second countdown: those expat tax allowances end on December 31, 2027, the same deadline as the separate-bonus method. From 2028 the picture changes for everyone, so a bonus that looks efficient now may be taxed differently in two years. Plan the next two bonus cycles knowing both clocks are running down together.
As the Daodejing says, 知足者富, he who knows he has enough is already rich; a bonus is a gift, not a plan, so take the method that keeps more of it and hold the rest lightly.
Where and when do I pick the bonus tax method?
In the 个人所得税 app, during the annual reconciliation that runs March 1 to June 30 of the following year. Under the salary section of the return, the 奖金计税方式选择 screen lets you flip the bonus between the two treatments and watch the refund change before you file.
Is a 13th-month salary taxed the same as a year-end bonus?
Yes, a lump-sum 13th month can ride the same separate method described above. The practical wrinkle: if you receive both a 13th-month salary and a discretionary bonus, point the method at whichever is larger and let the other be taxed as normal salary.
Does a bonus affect the six-year rule for expats?
No. The six-year clock counts your years of residence in China, not how much you earn, so a bonus changes what tax you pay, never your residency position. Only a qualifying break from China resets that clock; money never does.
Can I split my bonus into two payments to lower the tax?
No. The preferential separate method applies to one lump-sum bonus per person per year, so paying half in December and half in March does not buy you two low-rate calculations. Splitting usually hurts: the second slice is taxed as ordinary monthly salary at your marginal rate. The move that does help is the opposite one, keeping a single bonus a touch under a cliff threshold such as 36,000 yuan (USD 5,373), which you arrange with payroll before the bonus is set.
Do bonuses count toward my social insurance base?
Indirectly. Shanghai resets your contribution base each July from your previous year's average monthly pay, bonus included, so a big bonus can raise what you and your employer pay into social insurance next year, even though nothing extra is deducted from the bonus itself.
