Before you can file a tax statement or other related tax documents with the Philippine government, you must obtain a tax identification number (TIN). Natural-born citizens must file for a TIN. Additionally, juridical individuals -- those who have at least 60 percent of capital that is owned by a Philippine natural-born resident -- are also required to obtain a TIN before they can do business and file taxes in the country.
Complete BIR forms
Complete Bureau of Internal Revenue (BIR) applications. Fill out BIR Form 1901, the application for Mixed Income Individuals, Estates and Trusts (see Resources). Supply your name, residence and business address. Indicate the taxpayer type, such as sole proprietorship, estate, trust or professional. Include your telephone number, primary and secondary business names and line of business. Give the type of tax that you will be filing: income, percentage, withholding, estate or excise tax.
Keep in mind that if you are a non-citizen or juridical person, you must complete BIR Form 1902 (see resources). Identify whether you are a local or residential alien employee. Provide your name, address, telephone number and date of birth. Fill in your marital status and your spouse's name if you are married. Give the number of dependants that you have, including their names and dates of birth.
Provide required documentation, including your birth certificate. Supply the Department of Trade and Industry (DTI) Certificate of Registration of Business Name (see Resources). Create an online profile with DTI. Register your business name electronically with the department if you do not already have a registration. Include a mayor's permit or application for mayor's permit (see Resources) if you are requesting a TIN related to a business enterprise.
Submit the annual registration fee of 500 pesos with one of the authorized revenue district office agent banks (see Resources). Pay the Documentary Stamp Tax in the amount of 15 pesos at the agent bank as well.
Mail completed forms to the Revenue District Office (RDO) in your jurisdiction. Note that you can also submit applications and pay fees in person. The district office will issue you the TIN registration certificate. Before you can begin to conduct business in the Philippines, you must have an application on file with the RDO.
