Meaning
Quantitative method for calculating the individual income tax liability of non-residents based on their actual physical presence in the country. Using day count apportionment allows the tax bureau to determine what portion of a global salary is taxable under domestic law. A full day of presence is counted for any portion of a 24-hour period spent within the borders.
Presence Threshold
Status as a resident or non-resident changes once an individual exceeds 183 days of stay within a calendar year. Crossing this presence threshold subjects the taxpayer to worldwide income taxation in addition to income sourced from local work. The border control records provide the definitive evidence for this calculation.
Formula Application
Liability is determined by multiplying the total monthly tax by a fraction where the numerator is the number of days spent in China. This formula application ensures that an expatriate visiting a factory for two weeks only pays tax on half of their monthly compensation.
Employer Responsibility
Local companies must track the entry and exit dates of their foreign consultants to ensure accurate withholding. Fulfilling the employer responsibility avoids penalties for under-withholding when an employee remains in the country longer than originally planned. The tax office audits these records during the annual settlement period.
Discrepancies lead to the recalculation of the monthly tax base.
