Meaning
Revenue administration rules clarify the personal income tax obligations of non-resident individuals and the calculation of work days for those who lack a permanent home in the territory. This regulatory decree, sta announcement 2019 no 35, provides the detailed methodology for determining the tax liability of foreign employees based on their duration of stay and the source of their income. It introduces a specific formula for calculating the tax due for individuals who work both within and outside the country, ensuring that only the income related to local work is taxed.
The announcement also defines the reporting requirements for high-income individuals and those who serve as senior managers in local enterprises. It aligns the domestic personal income tax system with the latest international standards and the updated national tax law. This regulation is the primary guide for human resources and tax departments when managing the payroll of expatriate staff.
Work Day Calculation
Determination of the taxable period depends on a precise count of the days spent performing duties within the borders of the jurisdiction. Under the rules of sta announcement 2019 no 35, a work day is defined as any day or part of a day where an individual is physically present to perform their job. The calculation includes public holidays, weekends, and training days spent in the country if they are part of a work assignment.
However, days spent purely for personal travel or transit may be excluded if they are properly documented. The formula for tax calculation uses the ratio of local work days to the total days in the month to allocate the income. This ensures that a foreign employee is not overtaxed on their global salary.
The use of this standardized formula has significantly reduced the ambiguity in personal income tax filings for cross-border workers.
Income Sourcing
Allocation of earnings between different jurisdictions is based on the location where the services are actually rendered rather than where the payment is made. In the application of sta announcement 2019 no 35, the tax bureau distinguishes between income sourced within the country and income sourced abroad. Income from duties performed locally is always taxable, regardless of whether it is paid by a local or a foreign entity.
For individuals who are in the country for less than ninety days, or 183 days under a treaty, the income paid by a foreign employer may be exempt. However, this exemption does not apply to senior managers, who are taxed on their full salary attributed to their local role. The announcement provides clear criteria for identifying these high-level positions.
This ensures that the tax system captures the value generated by executive management within the territory.
Reporting Procedure
Compliance for non-resident employees involves a monthly or quarterly filing process that requires a detailed disclosure of their travel and income. According to sta announcement 2019 no 35, the individual or their employer must submit a report that shows the number of days spent in the country and the total salary earned. This report is used to calculate the tax using the prescribed formulas and to claim any applicable treaty benefits.
The taxpayer must keep copies of their passport and work contracts to support the data in the report. The tax bureau uses the national immigration records to verify the reported work days during its regular compliance checks. If an individual is found to have under-reported their days, they must pay the missing tax plus interest and may face a reduction in their credit rating.
The announcement also simplifies the process for individuals who work for multiple related companies. They can choose one company to act as their primary tax agent, which reduces the administrative burden. The final tax settlement at the end of the year allows for a reconciliation of any overpaid or underpaid tax.
This system provides a fair and transparent way to manage the tax obligations of a mobile workforce. It has made the jurisdiction more attractive for international talent by providing clear rules for tax planning. Proper documentation of every trip is the only way to ensure compliance with these rules.
The tax authorities continue to update their software to automate the calculations based on these formulas.
