Resident or local suppliers of goods and services, including nonresident aliens engaged in trade or business in the Philippines, are subject to a 1% creditable expanded withholding tax on their sales of goods and to a 2% creditable expanded withholding tax on their sales of services, if the payor is among the top 20,000 private corporations as classified by the BIR. Expanded withholding tax is a withholding tax that is prescribed for certain payors and that is creditable against the income tax due of the payee for the relevant tax quarter or year.
Professional fees are subject to a 15% creditable expanded withholding tax if such fees for the year exceed PHP720,000. Otherwise, the rate is 10%.
