China Individual Income Tax for Employers and Foreign Employees

China's top personal income tax rate is 45 per cent, and employers must withhold it. Singapore companies posting expats to China need to budget for their income tax from the start. Get the residency test or the deductions wrong, and the employee may owe additional tax while your company faces withholding penalties.

The rules have shifted in recent years. Since amendments to the Individual Income Tax (IIT) Law took effect on 1 January 2019, foreign employees have generally been taxed under the same framework as Chinese employees. Residency depends on domicile or a 183-day test. Preferential allowances for housing, children's education and language training were extended through 31 December 2027 by an announcement from China's Ministry of Finance and State Taxation Administration in August 2023.

Why does this matter now? The first six-year window under the worldwide-income rules closed on 31 December 2024, so long-serving expats face fresh exposure. Employers are also the statutory withholding agent, which means compliance failures bring surcharges and fines to your company, not just your staff.

In this blog, we discuss how expatriate income tax in China works in 2026. We cover residency, rates, deductions and allowances, employer withholding duties, social insurance and the China-Singapore tax treaty. We also share practical tables and budgeting tips so you can plan your first China postings with confidence.

How Does China Expat Income Tax Work for Your Team?

It all starts with residency: the number of days your employee spends in China determines which income is taxed and which deductions apply. China taxes individuals on a calendar-year basis under the IIT Law, which has applied to locals and foreigners alike since 1 January 2019. If starting a business in China is part of your wider plan, these residency rules will shape how you second staff.

1. The 183-Day Residency Test

An employee is a Chinese tax resident if they are domiciled in China or spend 183 days or more there in a calendar year. Residents are taxed on worldwide income. Non-domiciled staff present for fewer than 183 days are non-residents, taxed only on China-source income.

2. Worldwide Income and the Six-Year Rule

Non-domiciled residents get meaningful relief. Foreign-source income paid by an overseas entity or individual generally remains exempt during the first six qualifying years. Worldwide income becomes taxable in a seventh year if the employee spends at least 183 days in China. Each preceding year must have had at least 183 days in China and no single departure exceeding 30 days. The clock started on 1 January 2019, so the first window closed on 31 December 2024. A year under 183 days or a single departure exceeding 30 days resets the count. Holiday timing can therefore affect planning.

3. What Counts as China-Source Income

Salary for work performed physically in China is China-source income, even when paid from your Singapore payroll into an offshore account. Split-payroll arrangements do not change this. Bonuses tied to duties performed in China are also China-source.

What Are the 2026 IIT Rates and Deductions?

Resident expatriates' salaries generally face annual progressive rates of 3 to 45 per cent. Residents receive a standard annual deduction of RMB 60,000. Non-residents generally deduct RMB 5,000 per month from salary and use monthly rates. Residents' salary, bonuses and most cash allowances generally form part of 'comprehensive income', aggregated annually. The bands are set out in the Individual Income Tax Law administered by the State Taxation Administration of China. The table below shows the current brackets.

1. Standard and Special Deductions

Resident taxpayers, local or foreign, enjoy a standard deduction of RMB 60,000 per year. Non-resident employees generally deduct RMB 5,000 per month from salary. Special expense deductions cover common family costs. In 2023, monthly standards rose to RMB 2,000 per child for education and RMB 3,000 for elderly care. Employees claim these through the personal IIT app, and some can be shared between spouses. The qualifying categories include:

• Children's education and infant care
• Continuing education
• Serious-illness medical expenses
• Housing loan interest or housing rent
• Support for the elderly

2. Foreign-National Allowances Through 2027

Eligible foreign tax residents can choose tax-exempt housing, children's education and language-training allowances instead of special expense deductions. The Ministry of Finance and State Taxation Administration extended the allowance policy through 31 December 2027. Under Announcement No. 29 of 2023, the two regimes cannot be combined. Once made, the choice cannot be changed during the tax year.

3. Annual Bonuses and One-Off Payments

Employers may still tax a qualifying annual one-off bonus separately, using one-twelfth of the bonus to determine the monthly rate and quick deduction, then applying them to the full bonus. This separate treatment was likewise extended to 31 December 2027, and it can pull senior expats well below the 45 per cent top rate.

What Must Employers Withhold and File?

In China, the income payer is generally the statutory withholding agent; for salary paid by an overseas affiliate, a non-domiciled employee may self-declare or appoint the China employer to pay, subject to reporting requirements. Late payment attracts a daily surcharge of 0.05 per cent, and failure to withhold can also draw administrative fines. Your China entity remains responsible for its statutory withholding duties, even if it appoints a payroll provider to help administer them.

1. Register as a Withholding Agent

Your entity must be registered as a withholding agent with the competent local tax bureau when it is set up. This applies even where staff are partly engaged through a licensed staffing agency, and payroll records must support every calculation you make.

2. Withhold IIT on Every Payroll

Resident employees are withheld under the cumulative method, which spreads the progressive bands across the year. Non-residents are generally withheld on a monthly, per-transaction basis. Tax withheld is generally due by the 15th day of the following month, subject to official extensions for weekends and holidays.

3. Support the Annual Reconciliation

Resident employees reconcile between 1 March and 30 June when required, including where a top-up exceeds the applicable exemption thresholds, or when they choose to claim a refund. As withholding agent, you must issue income and withholding statements to each employee before the window opens, so they can file accurately through the IIT app.

How Does the China-Singapore Tax Treaty Prevent Double Taxation?

Your staff do not have to be taxed twice on the same salary. The double taxation agreement between Singapore and China, first signed in 1985 and updated by protocols since, follows the standard treaty pattern for employment income. Under the treaty, China cannot tax employment income where all three conditions are met:

• The employee spends fewer than 183 days in China in the relevant period
• The salary is paid by, or on behalf of, an employer that is not a China resident
• The cost is not borne by a permanent establishment the employer has in China

Where China does tax the salary, relief comes through a foreign tax credit on the Singapore side. The Inland Revenue Authority of Singapore (IRAS) administers this relief, and employees should obtain a Singapore certificate of residence before claiming treaty benefits. If you are weighing where to base your holding company, it is worth reading why many founders start a business in Singapore before expanding across the region.

Do Expats Pay China Social Insurance Too?

Generally yes — foreign employees are enrolled in Chinese social insurance under interim measures in force since 2011. The schemes cover pension, medical, unemployment, work injury and maternity insurance, with employer and employee both contributing. Rates are set city by city, so Shanghai and Shenzhen costs will differ.

Some countries have bilateral social insurance agreements with China that exempt seconded staff from certain contributions, so check whether yours applies before finalising a package. A handful of cities also expect foreign staff to join the housing provident fund. Confirm local rules before an assignment letter goes out.

How Should You Budget for Expat Tax Costs?

Start by modelling the gross-up. If an employment letter promises a net salary, you must gross it up, and at the 45 per cent band the employer-side cost climbs sharply. Build the expat income tax calculation into assignment budgets before any offer is signed, and remember the six-year rule when planning multi-year postings.

Support may offset other expansion costs. Singapore's Enterprise Singapore grants were consolidated into the EDGE Grant from 30 September 2026. The EDG, MRA and PSG closed on 29 September 2026. These can defray eligible market-entry activities. IRAS also administers the Double Tax Deduction for Internationalisation. It gives a 200 per cent deduction on qualifying market-expansion expenses. The automatic expenditure cap rises to S$400,000 per year of assessment from 2027.

Beyond individual tax, remember the corporate side — including how foreign companies repatriate profits from China — which needs its own planning alongside payroll. Getting both right from the start keeps cash moving where you need it.

China's IIT rules reward early planning. The 183-day test, the six-year worldwide-income window, the allowances election and your role as withholding agent together decide both compliance risk and assignment cost. Rates of 3 to 45 per cent, the RMB 60,000 standard deduction and treaty relief under the China-Singapore DTA are the numbers to model first.
