About TaxCalculator.ph
Free Philippine tax calculators and educational resources based on official BIR regulations
TaxCalculator.ph exists to simplify Philippine tax compliance for everyone. We provide free, accurate tax calculators and educational resources based on official Bureau of Internal Revenue (BIR) regulations.
The Problem We Solve:
Philippine tax regulations can be complex and difficult to navigate. The Bureau of Internal Revenue publishes tax tables, revenue regulations, and compliance requirements, but translating these into practical calculations requires time and expertise that many taxpayers don't have.
Our Solution:
We bridge the gap between official BIR regulations and everyday taxpayers by:
- Converting complex tax tables into simple, user-friendly calculators
- Explaining tax concepts in plain language with Filipino examples
- Citing specific BIR sources so you can verify information yourself
- Updating content when tax laws change
Our Commitment to Accuracy (E-E-A-T Standards)
TaxCalculator.ph follows Google's E-E-A-T quality guidelines for YMYL (Your Money Your Life) content:
Experience: We use official BIR sources and test all calculators against BIR examples
Expertise: Content is researched, written, and maintained by the TaxCalculator.ph editorial team, led by founder Aditya Aman, a tax-technology specialist. We are not licensed CPAs, tax attorneys, or financial advisers, so our authority comes from transparent methodology and primary-source citations, not professional licensure.
Authoritativeness: Every tax calculation cites specific Revenue Regulations, BIR Memorandum Circulars, or sections of the Tax Code, with visible review dates so you can check our work against the primary sources.
Trustworthiness: We clearly state what we are (an independent educational and estimation tool) and what we are NOT (financial, tax, legal, investment, or accounting advice, and not a substitute for the BIR or a licensed professional). Our results are estimates only and must not be relied upon for filing or financial decisions.
