Module C: Formula & Methodology Behind the Calculator
The calculator uses official BIR formulas to compute business income tax. Here’s the detailed methodology:
1. Regular Income Tax Calculation
For businesses opting for regular income tax (itemized deductions):
Taxable Income = Gross Revenue - Allowable Deductions Income Tax = Taxable Income × Applicable Tax Rate (from progressive table)
| Taxable Income Range (₱) | Tax Rate | Base Tax (₱) |
|---|---|---|
| 0 – 250,000 | 0% | 0 |
| 250,001 – 400,000 | 20% | 0 |
| 400,001 – 800,000 | 25% | 30,000 |
| 800,001 – 2,000,000 | 30% | 130,000 |
| 2,000,001 – 8,000,000 | 32% | 490,000 |
| Over 8,000,000 | 35% | 2,410,000 |
2. 8% Gross Income Tax
For eligible businesses (gross sales/receipts ≤ ₱3,000,000) opting for simplified taxation:
Income Tax = Gross Revenue × 8%
3. Quarterly Calculation
For quarterly payments, the annual tax is divided by 4, with adjustments for:
- First quarter: 50% of first quarter’s tax due
- Second quarter: 50% of first half’s tax due (less first quarter payment)
- Third quarter: 75% of first nine months’ tax due (less previous payments)
- Fourth quarter: Annual tax due (less previous payments)
Module D: Real-World Examples & Case Studies
Case Study 1: Freelance Graphic Designer (Sole Proprietorship)
Scenario: Annual revenue of ₱1,200,000 with ₱400,000 deductible expenses, opting for regular income tax.
Calculation:
Taxable Income = ₱1,200,000 - ₱400,000 = ₱800,000 Income Tax = ₱130,000 + (₱800,000 - ₱400,000) × 30% = ₱250,000 Quarterly Payment (Q1) = ₱250,000 × 50% × 25% = ₱31,250
Case Study 2: Small Retail Corporation
Scenario: Annual revenue of ₱5,000,000 with ₱3,000,000 deductible expenses, opting for regular income tax.
Calculation:
Taxable Income = ₱5,000,000 - ₱3,000,000 = ₱2,000,000 Income Tax = ₱490,000 + (₱2,000,000 - ₱2,000,000) × 32% = ₱490,000 Effective Tax Rate = ₱490,000 / ₱5,000,000 = 9.8%
Case Study 3: Online Seller (8% Gross Income Tax)
Scenario: Annual revenue of ₱2,500,000, opting for 8% gross income tax.
Calculation:
Income Tax = ₱2,500,000 × 8% = ₱200,000 Quarterly Payment = ₱200,000 / 4 = ₱50,000
Note: This option is only available for businesses with gross sales ≤ ₱3,000,000 annually.
