In the Philippines, senior citizens are entitled to a VAT exemption on certain goods and services as per RA 9994. This means they won't have to pay the standard 12% VAT on eligible items like food, medicines, and healthcare services. However, it's important for seniors to check which specific products and services are covered under this exemption. For detailed information and to ensure compliance, you may want to review the official guidelines or consult with the Bureau of Internal Revenue or a licensed tax professional.
