Previously, we discussed Revenue Regulation (RR) 11-2018, which provides for withholding tax rates on income payments made to individual/corporate citizens, resident aliens, and non-resident aliens. Specifically, the regulation provides for rates of “creditable withholding tax” (CWT) on certain income payments, like ordinary and necessary business expenses, that may be applied against the income tax due of the payee for the taxable year the income was earned.
