The Tax Deductions Expats in Shanghai Often Miss (2026)

If you pay tax in Shanghai and you have a child, a mortgage, a rented flat, or a parent over 60 you help support, you can take between ¥800 and ¥3,000 a month (about USD 120 to 450) off your taxable income through China's special additional deductions, the 专项附加扣除. The catch is that you have to claim them yourself, and you cannot take them at the same time as the expat tax-free allowances, which end on December 31, 2027.

What are China's special additional deductions?

China's special additional deductions are seven categories of ordinary spending the tax authority lets a Shanghai taxpayer subtract from taxable income: children's education, infant care, your own further study, big medical bills, mortgage interest, rent, and supporting elderly parents. They are not a rebate cheque. Each one lowers the income your tax is calculated on, so the money you keep is the deduction multiplied by your marginal rate. They have been open to expats who are tax residents since 2019, and most eligible expats we know have never filed a single one.

The catch nobody explains: deductions or the allowances, not both

Here is the part that trips people up. For years, a well-structured expat package in Shanghai has leaned on tax-free allowances instead: housing, children's school fees, language training and home-leave flights paid as exempt benefits rather than salary. Chinese law lets an expat choose that route, or the special additional deductions, but not both in the same year. That choice was due to disappear once, was extended, and now runs only until the end of 2027. From January 1, 2028, the allowances are gone and the deductions are all that is left. We wrote about that deadline in the allowances ending in 2027, and it is the reason this is worth sorting now rather than in three years.

The seven deductions, and what each is worth

These are the 2026 figures, unchanged since the three family deductions were raised on January 1, 2024. Read the middle column as a reduction in taxable income, not a cash payment.

Amounts are what comes off your taxable income, not cash back. Converted at about ¥6.7 to US$1, a September 2026 ballpark. The tax you actually save is the deduction times your marginal rate, roughly 10 to 45 percent.

You cannot claim rent and mortgage interest together, so pick whichever is larger. For most renters in Shanghai that is the ¥1,500 (USD 224) rent line. If you earn enough to sit in the 25 or 30 percent tax band, that rent deduction alone is worth roughly ¥375 to ¥450 (USD 56 to 67) a month back in your pocket.

How do you actually claim them?

Everything runs through one official app, 个人所得税, from the State Taxation Administration (not a bank, not your employer's HR system). Register with your passport and Chinese phone number, open 专项附加扣除填报, choose the tax year, and enter the details for each deduction you qualify for: your tenancy contract and landlord's ID number for rent, the school for a child, a parent's ID for elderly support. You then decide whether your employer applies it to your monthly withholding, or you claim it all back in the annual reconciliation, 汇算清缴, which runs March to June for the previous year. Keep the paperwork, because the tax office can ask for it later.

The honest snag: the app is Chinese only, with no English mode. Have your payroll contact or a Chinese-reading friend sit with you for the fifteen minutes it takes, and it is done for the year. If you would rather not touch salary withholding at all, wait and claim the whole lot in the spring reconciliation instead. Either way you are working inside the same system as income tax and the six-year rule.

Which should you pick, allowances or deductions?

If your contract already gives you large tax-free allowances, housing and international-school fees especially, those are almost always worth more than the capped deductions, because school fees alone dwarf a ¥2,000 (USD 300) monthly line. Keep them until they expire. If your package has no such allowances, or only small ones, the special additional deductions are money you are currently leaving on the table, so file them. And whichever you are on today, set the deductions up before January 1, 2028, because after that they are the only relief left. It is worth reading this next to what salary you need to live well here, since the two decide your real take-home together.

As the Doctrine of the Mean puts it, 凡事预则立，不预则废, plan ahead and you stand, fail to and you fall. Tax relief you set up early is relief you actually keep.
