Comprehensive Guide to 2018 Taxable Income in the Philippines (TRAIN Law)
The Tax Reform for Acceleration and Inclusion (TRAIN) Law, officially known as Republic Act No. 10963, significantly changed the Philippine tax system when it took effect on January 1, 2018. This guide provides a complete breakdown of how taxable income was calculated under the new system, including the revised tax tables, deductions, and exemptions.
Key Changes Introduced by TRAIN Law in 2018
- Lower personal income tax rates for most taxpayers, especially those earning below ₱8 million annually
- Increased personal exemptions from ₱50,000 to ₱250,000 for single individuals and from ₱100,000 to ₱500,000 for families
- Simplified tax tables with only 7 brackets instead of the previous progressive system
- Removal of certain exemptions like the 13th month pay and other benefits exemption cap (previously ₱82,000)
- Introduction of new taxes on sugar-sweetened beverages, cosmetic procedures, and other goods

| Head of Family | 250,000 | 25,000 | 4 dependents (₱100,000) |
Allowable Deductions from Gross Income
Under the TRAIN Law, taxpayers could choose between:
- Itemized Deductions – Actual expenses incurred (with proper receipts):
- Business expenses (for self-employed)
- Premiums on health and/or hospitalization insurance (up to ₱2,400/year)
- Contributions to SSS, GSIS, PhilHealth, and Pag-IBIG
- Charitable contributions (limited to 10% of taxable income)
- Home mortgage interest (for principal residence)
- Optional Standard Deduction (OSD) – 40% of gross sales/receipts (for self-employed and professionals) with a maximum of ₱800,000
Step-by-Step Calculation of Taxable Income
To compute your taxable income for 2018:
- Determine Gross Income – Sum all income from employment, business, investments, and other sources
- Subtract Non-Taxable Income – Remove items like:
- 13th month pay and other benefits (up to ₱90,000 total)
- De minimis benefits (e.g., rice subsidy, uniforms)
- Gifts, bequests, and devises
- Apply Deductions – Choose between itemized deductions or OSD (for self-employed)
- Subtract Personal Exemptions – Based on your filing status and dependents
- Compute Tax Due – Apply the progressive tax rates to the resulting taxable income
Common Mistakes to Avoid
- Double-counting exemptions – The ₱90,000 exemption for 13th month pay is separate from personal exemptions
- Incorrect filing status – Married individuals must choose between joint or separate filing
- Missing receipts for itemized deductions – Without proper documentation, deductions may be disallowed
- Forgetting to include all income sources – Even small side incomes must be declared
- Using wrong tax tables – The 2018 rates differ significantly from pre-TRAIN rates
