In the landscape of Philippine taxation, the distinction between "Single" and "Married" individuals was once a primary determinant of one’s tax liability. However, following the enactment of Republic Act No. 10963, otherwise known as the Tax Reform for Acceleration and Inclusion (TRAIN) Law, which took effect on January 1, 2018, the legal framework underwent a seismic shift.
To understand the current state of income tax differences, one must look at both the historical context of personal exemptions and the modern unified tax schedule.
1. The Pre-TRAIN Era: Personal and Additional Exemptions
Prior to 2018, the National Internal Revenue Code (NIRC) provided distinct "Personal Exemptions" based on civil status. A single individual was entitled to a basic personal exemption of ₱50,000, while married individuals were entitled to the same amount, but with the added benefit of "Additional Exemptions" for qualified dependents (₱25,000 per child, up to four children).
Under this old regime, marital status and the number of children significantly lowered the taxable income base. A married person with four children could shield up to ₱150,000 of their income from taxation, whereas a single person without dependents could only shield ₱50,000.
2. The TRAIN Law: Structural Uniformity
The TRAIN Law effectively abolished the distinction between single and married taxpayers regarding personal and additional exemptions. Under the current Tax Code, the following rules apply regardless of civil status:
- Removal of Personal Exemptions: The ₱50,000 personal exemption and the ₱25,000 additional exemption per dependent have been integrated into a higher "Tax-Exempt Threshold."
- The ₱250,000 Threshold: All individual taxpayers, whether single, married, or head of household, whose annual gross income does not exceed ₱250,000 are exempt from income tax.
- Unified Tax Schedule: Both single and married individuals follow the same graduated tax table. Whether you are a single professional or a married parent of three, the tax rates (ranging from 15% to 35% for income above ₱250,000) remain identical.
3. Spousal Filing: Separate vs. Consolidated
While the tax rates are the same, the administration of taxes for married couples involves specific legal nuances under Section 51(D) of the NIRC:
- Mandatory Joint Filing: Married individuals (whether citizens or resident aliens) who derive income from any source within the Philippines are required to file a single joint return for the taxable year.
- Separate Computation: Although the return is joint, the actual computation of the tax is done separately. The income of the husband and the wife are calculated individually to determine their respective tax liabilities. These two amounts are then added together to arrive at the total tax due for the couple.
- Unidentifiable Income: If a particular income cannot be definitely attributed to either spouse (e.g., income from a conjugal property where the specific contribution isn't clear), it is divided equally between the spouses for the purpose of computing their individual income tax.
4. Taxation of Business Income and Professional Fees
For married individuals who are also "Self-Employed and/or Professionals" (SEP), the law allows for a choice:
- Graduated Rates: Use the same graduated table as salaried employees.
- 8% Flat Rate: If gross sales/receipts do not exceed the VAT threshold (₱3,000,000), the individual may opt for an 8% tax on gross sales in excess of ₱250,000.
Importantly, if both spouses are SEPs, they each get their own ₱250,000 deduction if they opt for the 8% tax rate, provided their individual gross incomes are handled separately.
5. Passive Income and Other Taxes
Marital status generally has no bearing on "Final Taxes" on passive income. The rates for the following remain constant for all individuals:
- 20% Final Tax on interest from bank deposits.
- 10% Final Tax on cash and/or property dividends.
- 6% Capital Gains Tax on the sale of real property.
Summary Table: Single vs. Married (Post-2018)
| Feature | Single Taxpayer | Married Taxpayer |
|---|---|---|
| Basic Exemption | None (Abolished) | None (Abolished) |
| Dependent Exemption | None (Abolished) | None (Abolished) |
| Tax-Exempt Threshold | First ₱250,000 of income | First ₱250,000 of income (per spouse) |
| Filing Requirement | Individual Return | Joint Return (with separate computation) |
| Tax Rates | Graduated (15% - 35%) | Graduated (15% - 35%) |
Conclusion
In the current Philippine legal context, marital status has been largely neutralized as a factor for determining income tax liability. The shift from "status-based" exemptions to a "flat-threshold" system reflects a move toward simplified tax administration. While married couples are bound by the procedural requirement of filing a joint return, the substantive tax burden is calculated individually, ensuring that marriage itself does not result in a "marriage penalty" or a significant tax advantage over single individuals.
