Every spring, foreign employees in China confront the same ritual: the annual individual income tax (IIT) reconciliation, known in Mandarin as the “comprehensive income annual settlement.” It is the moment when the State Taxation Administration reconciles what was withheld from your salary each month against what you actually owe for the full year — and either refunds the difference or collects it. For foreigners and the companies that employ them, understanding this process in advance prevents surprise tax bills and missed refunds. This guide explains how the China IIT annual settlement works in 2026, who must file, and what foreign employees and employers should watch for.
- The annual IIT settlement consolidates four income types — wages, labor remuneration, author’s remuneration, and royalties — into one reconciled tax bill.
- The filing window runs from March 1 to June 30 each year, covering the previous calendar year’s income.
- Foreign employees file through the State Taxation Administration’s Individual Income Tax app, through their employer, or at a tax service hall.
- Most foreign employees are taxed only on China-sourced income until they pass the six-year residency threshold for worldwide income.
- An underpayment must be settled by the deadline, while a refund is paid directly to your bound bank card.

What the annual settlement actually reconciles
During the year, your employer withholds IIT from your salary every month at the progressive rate that applies to your bracket. But monthly withholding is an estimate. The annual settlement adds up your full-year “comprehensive income” — wages and salaries, labor remuneration, author’s remuneration, and royalties — applies the annual standard deduction of RMB 60,000 and any additional deductions, then recalculates your true tax under the seven-bracket progressive scale, which runs from 3% up to 45%.
If the total withheld during the year exceeds what the final calculation shows you owe, you get a refund. If it falls short — which happens when you earned from multiple employers, switched jobs mid-year, or received side income not fully withheld — you owe the difference. This is the same annual-reconciliation logic that businesses face with their own corporate income tax annual reconciliation, applied to individuals.
Who must file, and who can skip it
Not everyone is required to file. You must complete the annual settlement if any of the following apply: your comprehensive income exceeded RMB 120,000, you had a refund due from over-withholding, your annual tax was under-withheld, you had comprehensive income from two or more sources, or you want to claim special additional deductions that were not captured during the year. Employees whose income was fully and accurately withheld by a single employer and who have no refund or underpayment generally do not need to file.
For foreign employees, the same rules apply, but with one important nuance: your tax residency status determines whether the settlement covers only China-sourced income or worldwide income. We cover that distinction below.
The 2026 calendar and how filing works
The annual settlement for 2025 income ran from March 1 through June 30, 2026, and the next cycle — for 2026 income — opens on March 1, 2027. Foreign employees file in one of three ways: through the Individual Income Tax app published by the State Taxation Administration, by authorizing their employer to file on their behalf, or in person at the tax service hall of the local tax authority, such as the Guangzhou Municipal Tax Service for companies in the Pearl River Delta.
The app is the most common route. You log in with your tax account, confirm your income and withholding records, add or correct deductions, and the system computes your refund or amount due. Refunds are paid to a bank card you bind in the app; underpayments must be settled before the June 30 deadline to avoid late-payment surcharges and interest. In practice, most foreign employees we support resolve their settlement entirely online, which matters because many travel outside China during the filing window.
Deductions that reduce your bill
Beyond the RMB 60,000 annual standard deduction, taxpayers can claim six special additional deductions: children’s education, continuing education, serious illness medical expenses, housing loan interest, housing rent, and support for elderly parents. Each has a monthly or annual cap. A foreign employee renting an apartment in Shenzhen or Guangzhou, for example, can deduct qualifying housing rent up to the local monthly limit, while an employee supporting a parent can claim the elderly-support deduction.
The practical point for foreign staff is that these deductions only lower your tax if they are actually claimed. When a deduction is missed during monthly withholding, the annual settlement is your chance to add it and recover the overpaid amount as a refund. This is one of the most common sources of refunds we see for expatriate employees.
Foreign-specific residency and allowance rules
Two rules matter most for foreigners. First is the 183-day residency test: an individual without a domicile in China who stays less than 183 days in a calendar year is generally taxed only on China-sourced income, while one who stays 183 days or more is treated as a resident taxpayer for that year. Second is the six-year rule: a non-domiciled individual only becomes subject to tax on worldwide income after being resident for 183 days or more in six consecutive calendar years. Because the 2019–2023 period is not counted under the transitional rules, the worldwide-income clock effectively began in 2024 for most long-staying expatriates.
Foreign employees can also choose between two allowance systems for the overlapping items: the legacy tax-free foreigner allowances (housing, meals, laundry, language training, children’s education, and home leave) or the standard six special additional deductions — but not both for the same item. The choice is made annually and can materially change your final liability, so it is worth reviewing with a payroll professional familiar with expatriate compensation each year.
Common mistakes that trigger underpayments
In our payroll work for foreign-invested companies across Guangzhou, Shenzhen, and Dongguan, the same errors recur every filing season. The most frequent is failing to account for side income — a second employer, freelance consulting, or royalties — that was not subject to full withholding. Another is assuming the six-year rule has already made you subject to worldwide income when, for most expatriates, it has not. A third is claiming both a legacy allowance and a standard deduction for the same item, which triggers a correction on review.
As a member of the European Union Chamber of Commerce in China (South China Chapter), we advise foreign employers to treat the annual settlement as a compliance checkpoint, not a one-off filing: reconcile each expatriate’s residency status, income sources, and deductions before the window opens, so there are no surprises when the app presents its final number.
What employers should do before the window opens
Employers do not owe the tax themselves, but they carry real obligations: accurate monthly withholding, correct IIT withholding rates and brackets for each employee, and support when staff authorize company-assisted filing. A clean year of withholding makes the annual settlement a formality; a messy one turns it into a scramble. If you have not already, review your payroll records and confirm each foreign employee’s residency status and allowance elections well before the next filing window.
For teams hiring across China, the same preparation applies regardless of city. Our guide to hiring employees in China and our breakdown of year-end bonus taxation cover the withholding side of the equation that feeds directly into the annual settlement.
Frequently Asked Questions
When is the China IIT annual settlement deadline?
The filing window runs from March 1 to June 30 each year, covering the previous calendar year’s income. The settlement for 2026 income opens on March 1, 2027.
Do I need to file if my employer already withheld tax every month?
Not necessarily. If your income was fully and accurately withheld by a single employer and you have no refund due and no underpayment, you are generally not required to file.
Are foreign employees taxed on worldwide income in China?
Most are not. A non-domiciled individual is only taxed on worldwide income after being resident for 183 days or more in six consecutive calendar years, and the 2019–2023 period is not counted toward that threshold.
Can I claim both the foreigner allowances and the standard deductions?
No. For overlapping items such as housing and children’s education, you must choose either the legacy foreigner allowances or the standard special additional deductions — never both for the same item.
How do I receive a refund from the annual settlement?
Refunds are paid directly to a bank card you bind in the Individual Income Tax app. Underpayments must be settled before the June 30 deadline to avoid late-payment charges.
Whether you are a foreign employee preparing for your own settlement or an employer managing payroll for an expatriate team, getting the annual IIT reconciliation right is easier with a partner who knows the rules.
