Why the Difference Matters
When you receive a job offer, the number discussed is usually your gross monthly pay. But when computing tax limits—like the ₱20,833 monthly zero-tax threshold—the BIR looks at your taxable compensation, not your gross pay.
This means a person earning a gross salary of ₱22,000 might actually pay zero withholding tax because their taxable compensation falls below the ₱20,833 threshold after statutory deductions are subtracted.
What Gets Deducted from Gross to Arrive at Taxable?
1. Mandatory Employee Contributions: Your share of SSS, PhilHealth, and Pag-IBIG is strictly considered non-taxable by the BIR and is removed from the tax base.
2. De Minimis Benefits: Qualified benefits that meet their BIR category conditions and applicable limits (like a ₱2,500/month rice subsidy) are not part of taxable compensation.
3. Other specific non-taxable compensation allowed by law, such as the ₱90,000 exclusion for 13th month pay and other benefits.
Frequently asked questions
Are allowances part of taxable compensation?
It depends. "De minimis" benefits within BIR limits are non-taxable. Other allowances are generally considered taxable compensation unless specifically exempted.
Does PhilHealth use gross pay or taxable compensation?
Neither. PhilHealth uses "Monthly Basic Salary" (MBS), which excludes allowances, overtime, and bonuses. Pag-IBIG, on the other hand, uses "Fund Salary" which includes allowances.
