Individual Income Tax: Classification, Rates, and the 8% Option

Individual income taxation turns on the taxpayer's classification and category. This section covers resident and nonresident citizens and aliens, the graduated rate table in effect from January 1, 2023, the three categories of individual taxpayers (compensation earners, self-employed individuals and professionals, and mixed income earners), and the optional 8% gross income tax.

1. Classification of Individual Taxpayers and Territorial Tax Base

The Philippine tax code classifies individual taxpayers along two principal axes: citizenship (citizen vs. alien) and residency (resident vs. non-resident). An individual's classification dictates whether their tax base is worldwide or limited to Philippine sources.

• Graduated rates or 8% SEP              • Graduated rates or 8% SEP              • Graduated rates or 8% SEP (RA)

Taxpayer Classifications and Legal Criteria

1. Resident Citizen (RC): A Filipino citizen residing permanently or indefinitely within the Philippines. An RC is the only individual taxpayer taxed on worldwide net income (income derived from sources within and outside the Philippines).
2. Non-Resident Citizen (NRC): A Filipino citizen who:
   • Establishes to the satisfaction of the CIR the fact of physical presence abroad with a definite intention to reside permanently abroad;
   • Leaves the Philippines during the taxable year to reside abroad as an immigrant or for permanent employment;
   • Works and derives income abroad requiring physical presence abroad most of the time (at least 183 days during the calendar year). Overseas Filipino Workers (OFWs) and registered Filipino sea-based vessel crewmen are statutory NRCs.
   • Tax Base: Taxed strictly on Philippine-source income only.
3. Resident Alien (RA): An individual who is not a citizen of the Philippines but whose residence is within the Philippines (e.g., an expatriate who stays in the country for an extended period without a definite intention as to their stay). Tax Base: Taxed strictly on Philippine-source income only.
4. Non-Resident Alien Engaged in Trade or Business (NRA-ETB): An alien who comes to the Philippines and stays for an aggregate period of more than 180 days during any calendar year. An alien who actually engages in business or practice of profession in the Philippines is classified as an NRA-ETB. Tax Base: Taxed on net Philippine-source income at graduated tax rates.
5. Non-Resident Alien Not Engaged in Trade or Business (NRA-NETB): An alien who stays in the Philippines for an aggregate period of 180 days or less during the calendar year. Tax Base: Subject to a flat 25% final withholding tax on gross Philippine-source income under Section 25(B). No deductions or personal allowances are permitted.

2. Individual Graduated Tax Rates under the TRAIN Law

Under Section 24(A)(2)(b) of the NIRC, as amended by the TRAIN Law, the graduated income tax brackets effective January 1, 2023 onward are structured as follows:

Abolition of Personal Exemptions: Under the TRAIN Law, the former Basic Personal Exemption (PHP 50,000) and Additional Exemptions for Dependents (PHP 25,000 per child) were completely eliminated. In their place, Congress built the personal relief directly into the PHP 250,000 zero-rate first bracket, ensuring that the first PHP 250,000 of taxable income is fully exempt for all individual taxpayers.

3. Taxpayer Categories: Compensation vs. SEP vs. Mixed Income

The tax code divides individual taxpayers into three distinct functional categories:

                                    Categories of Individual Taxpayers
                                                    │
         ┌──────────────────────────────────────────┼──────────────────────────────────────────┐

Purely Compensation Earner                  Purely Self-Employed / Professional        Mixed Income Earner
• Taxed strictly under graduated rates      • Option 1: Graduated + Itemized           • Compensation: Strictly Graduated
• Deductions NOT allowed                    • Option 2: Graduated + OSD (40%)          • Business: Graduated (Itemized/OSD)
• Substituted filing if qualified           • Option 3: Optional 8% Gross Tax            OR Optional 8% (no PHP 250K ded.)

Category 1: Purely Compensation Earners

• Individuals earning income exclusively from an employer-employee relationship.
• Taxable Base: Gross compensation less statutory exclusions (mandatory SSS/GSIS/PhilHealth/HDMF contributions and non-taxable benefits up to PHP 90,000).
• Mandatory Tax Treatment: Must be taxed strictly under the graduated income tax rates.
• No Deductions: Cannot claim Itemized Deductions, Optional Standard Deduction (OSD), or the 8% optional gross income tax.
• Substituted Filing System: Employees who receive purely compensation income from a single employer in a calendar year, and whose employer correctly withheld income tax (BIR Form 2316), are not required to file an annual income tax return (BIR Form 1700). The employer's filed withholding certificate serves as the substitute return.

Category 2: Purely Self-Employed Individuals / Professionals (SEP)

• Individuals earning income exclusively from the conduct of a trade, business, or the independent practice of a profession (single proprietors, freelance consultants, doctors, CPAs, lawyers).
• Available Tax Regimes:
  1. Graduated Rates with Itemized Deductions: Gross revenue less allowable business expenses under Section 34, plus 3% percentage tax under Section 116 (if non-VAT) or 12% VAT.
  2. Graduated Rates with Optional Standard Deduction (OSD): Gross revenue less 40% OSD, plus percentage tax or VAT.
  3. Optional 8% Gross Income Tax: 8% tax on gross sales/receipts exceeding PHP 250,000, in lieu of graduated income tax and Section 116 percentage tax.

Category 3: Mixed Income Earners

• Individuals who derive income concurrently from both compensation employment and an independent trade, business, or professional practice.
• Compensation Component: Must always be taxed under the graduated income tax rates. No business deductions can be offset against compensation income.
• Business / Professional Component: May choose either:
  • Graduated Rates: Net business income (using Itemized Deductions or 40% OSD) taxed under graduated rates, combined with compensation income; OR
  • Optional 8% Gross Income Tax: 8% levied on total gross sales/receipts (without the PHP 250,000 deduction).

4. The Optional 8% Gross Income Tax Regime

Introduced by the TRAIN Law under Section 24(A)(2)(b) and clarified by Revenue Regulations No. 8-2018, the Optional 8% Gross Income Tax provides a simplified compliance mechanism for micro, small, and medium self-employed individuals.

Eligibility Criteria

To qualify for the 8% gross income tax, an individual must satisfy four concurrent requirements:

1. Gross Sales/Receipts Threshold: Total gross sales, gross receipts, and other non-operating income must not exceed the statutory VAT threshold of PHP 3,000,000 during the taxable year.
2. Tax Type Limitation: The taxpayer must be subject only to the 3% Percentage Tax under Section 116. Taxpayers subject to other percentage taxes under Title V (e.g., common carriers under Section 117, amusement taxes under Section 125, banks under Section 121) are disqualified.
3. Entity Disqualification: Partners in a General Professional Partnership (GPP) cannot avail of the 8% optional tax for their distributive share in GPP profits.
4. Timely Election: The election must be signified in the 1st Quarter Quarterly Income Tax Return (BIR Form 1701Q) or upon initial BIR registration. Once made, the election is irrevocable for that taxable year. If the taxpayer fails to signify the election in the 1st quarter, they are automatically placed under the graduated rates.

Computational Rules: Purely SEP vs. Mixed Income Earner

1. Purely Self-Employed / Professional

$\text{Tax Due} = (\text{Gross Sales/Receipts} + \text{Non-Operating Income} - \text{PHP }250{,}000) \times 8\%$ Key Rule: The taxpayer receives a PHP 250,000 reduction against gross receipts because they have no compensation income to absorb the zero-rate first bracket.

2. Mixed Income Earner

• On Compensation Income: Taxed under graduated rates (the PHP 250,000 zero-rate bracket is automatically absorbed by compensation).
• On Business / Professional Income: $\text{Tax Due on Business} = (\text{Gross Sales/Receipts} + \text{Non-Operating Income}) \times 8\%$ Key Rule: The PHP 250,000 deduction is NOT allowed against business receipts because it was already applied to compensation income.

Comprehensive Worked Comparison Example

Scenario: Atty. Santos, a licensed lawyer, generated PHP 2,400,000 in professional fees during 2024. Her actual substantiated operating expenses totaled PHP 1,000,000. She is not VAT-registered. Let us compare her total annual tax burden across all three available methods:

Method 1: Graduated Rates with Itemized Deductions

• Gross Professional Receipts: PHP 2,400,000
• Less: Itemized Business Expenses: PHP 1,000,000
• Taxable Net Income: $\text{PHP }2{,}400{,}000 - \text{PHP }1{,}000{,}000 = \text{PHP }1{,}400{,}000$
• Income Tax Due (under 2023 graduated table):
  • Base tax on PHP 800,000: PHP 102,500
  • Excess over PHP 800,000: $(\text{PHP }1{,}400{,}000 - \text{PHP }800{,}000) \times 25\% = \text{PHP }600{,}000 \times 25\% = \text{PHP }150{,}000$
  • Income Tax Due: $\text{PHP }102{,}500 + \text{PHP }150{,}000 = \text{PHP }252{,}500$
• Percentage Tax under Section 116 (3% of gross receipts):
  • $\text{Percentage Tax} = \text{PHP }2{,}400{,}000 \times 3\% = \text{PHP }72{,}000$
• Total Annual Tax Burden: $\text{PHP }252{,}500 + \text{PHP }72{,}000 = \text{PHP }324{,}500$

Method 2: Graduated Rates with Optional Standard Deduction (OSD)

• Gross Professional Receipts: PHP 2,400,000
• Less: OSD (40% of gross receipts): $\text{PHP }2{,}400{,}000 \times 40\% = \text{PHP }960{,}000$
• Taxable Net Income: $\text{PHP }2{,}400{,}000 - \text{PHP }960{,}000 = \text{PHP }1{,}440{,}000$
• Income Tax Due (under 2023 graduated table):
  • Base tax on PHP 800,000: PHP 102,500
  • Excess over PHP 800,000: $(\text{PHP }1{,}440{,}000 - \text{PHP }800{,}000) \times 25\% = \text{PHP }640{,}000 \times 25\% = \text{PHP }160{,}000$
  • Income Tax Due: $\text{PHP }102{,}500 + \text{PHP }160{,}000 = \text{PHP }262{,}500$
• Percentage Tax under Section 116 (3% of gross receipts): PHP 72,000
• Total Annual Tax Burden: $\text{PHP }262{,}500 + \text{PHP }72{,}000 = \text{PHP }334{,}500$

Method 3: Optional 8% Gross Income Tax

• Gross Professional Receipts: PHP 2,400,000
• Less: Statutory Reduction: PHP 250,000
• Taxable Base: $\text{PHP }2{,}400{,}000 - \text{PHP }250{,}000 = \text{PHP }2{,}150{,}000$
• Tax Due: $\text{PHP }2{,}150{,}000 \times 8\% = \text{PHP }172{,}000$
• Percentage Tax under Section 116: PHP 0 (The 8% tax is explicitly in lieu of both graduated income tax and Section 116 percentage tax).
• Total Annual Tax Burden: PHP 172,000

Comparative Analysis: By electing the Optional 8% tax regime, Atty. Santos achieves total tax savings of PHP 152,500 compared to Itemized Deductions (PHP 324,500 - PHP 172,000) and PHP 162,500 compared to OSD (PHP 334,500 - PHP 172,000), while entirely eliminating the requirement to substantiate expenses with supplier receipts.
