TRAIN Law Tax Guide — Withholding Tax, Brackets, and Buwis on Your Payslip

What is TRAIN Law tax?

The TRAIN Law (RA 10963) reformed Philippine individual income tax to reduce rates for many low- and middle-income earners while adjusting excise taxes elsewhere. For employees, the most visible effect is withholding tax on compensation — income tax your employer deducts each payday and remits to the Bureau of Internal Revenue (BIR) on your behalf. It is not a separate "payroll fee"; it is prepayment of your annual income tax liability.

TRAIN replaced the older bracket structure with graduated rates applied to annual taxable compensation income. The first ₱250,000 of taxable income per year is taxed at 0%. Income from ₱250,001 to ₱400,000 is taxed at 15% of the excess over ₱250,000. Higher income faces 20%, 25%, 30%, and 35% on successive brackets defined in the Tax Code as amended. These brackets have been effective since 1 January 2023 and remain unchanged for 2026 unless Congress enacts new law.

On payslips, this deduction may appear as "Withholding Tax," "WT," "Income Tax," or buwis — the everyday Filipino term for tax. The amount fluctuates when your taxable income changes, when you receive bonuses, or when payroll annualizes your income differently after a mid-year raise.

BIR revenue regulations and official withholding tables are published at bir.gov.ph. Our Official Resources page links to BIR documents. Tax rules may change with new legislation — verify brackets before filing disputes or annual returns.

Who pays withholding tax

• Rank-and-file and managerial employees receiving taxable compensation above the zero-tax threshold when annualized.
• Employees with multiple income sources may still have withholding on primary employment while owing additional tax on combined annual income when filing the ITR.
• Minimum-wage earners in qualified sectors may be exempt under separate rules when properly certified — most standard private-sector payrolls above the exempt threshold withhold normally.
• Freelancers and pure self-employed workers are not subject to withholding on compensation in the same way; they pay via quarterly filings and annual ITR instead.

Exemption from withholding on a particular payslip does not always mean zero tax for the entire year. A bonus-heavy December or taxable allowances can create tax even when earlier months showed ₱0 buwis.

Requirements checklist

• Correct TIN on file with employer and BIR
• BIR Form 2316 (or equivalent) issued after year-end showing total withholding
• Understanding of which pay elements are taxable vs non-taxable in your company
• Payslip access each cutoff showing withholding tax / buwis line
• Records of 13th month and bonuses exceeding the ₱90,000 tax-exempt benefits cap
• Annual ITR filing or employer-facilitated filing if applicable to your employment setup

Employers must remit withheld taxes to BIR on schedule and issue Form 2316 summarizing your year's compensation and tax withheld. Keep Form 2316 — it is the starting point for personal ITR filing and refund claims.

2026 tax brackets

Annual taxable compensation income under TRAIN (effective 2023 schedule, unchanged for 2026):

• Up to ₱250,000: 0% — fully exempt
• ₱250,001 – ₱400,000: 15% of excess over ₱250,000
• ₱400,001 – ₱800,000: ₱22,500 + 20% of excess over ₱400,000
• ₱800,001 – ₱2,000,000: ₱102,500 + 25% of excess over ₱800,000
• ₱2,000,001 – ₱8,000,000: ₱402,500 + 30% of excess over ₱2,000,000
• Over ₱8,000,000: ₱2,202,500 + 35% of excess over ₱8,000,000

Example at the second bracket: taxable income ₱350,000 annually → tax = 15% × (₱350,000 − ₱250,000) = ₱15,000 per year, or roughly ₱1,250 per month if spread evenly.

Monthly salary alone does not map cleanly to brackets because payroll systems annualize — multiplying taxable monthly pay by 12 and adjusting for YTD bonuses, non-taxable allowances, and mandatory contribution exclusions before applying the table.

Step-by-step: read buwis on payslip

1. Find the withholding tax line. Look for "Withholding Tax," "WT," "Income Tax," or "Buwis."
2. Note taxable income for the period. Some payslips show taxable gross separately from total gross.
3. Subtract mandatory contributions. Confirm SSS, PhilHealth, and Pag-IBIG were excluded from taxable base per payroll policy.
4. Annualize mentally. Multiply taxable monthly income by 12 and add known taxable bonuses projected for the year.
5. Apply TRAIN brackets. Check whether annualized taxable income exceeds ₱250,000 — that is when monthly buwis typically begins for steady earners.
6. Compare with SweldoSense. Run the same gross through our salary calculator or net pay calculator to see estimated withholding alongside statutory deductions.
7. Reconcile at year-end. Match total withholding on Form 2316 against payslip YTD totals before filing your ITR.

When tax is remitted

Employers remit withheld compensation tax to BIR according to monthly or semimonthly schedules depending on employer classification and BIR regulations. The deduction on your payslip reflects employer obligation to prepay your tax — remittance timing is the employer's compliance matter, not a separate employee payment step.

If withholding stops unexpectedly mid-year without a corresponding change to non-taxable status, verify with HR whether a payroll configuration error occurred — under-withholding creates a surprise bill at ITR time; over-withholding may mean a refund claim instead.

Rates and exemptions

There is no separate "BIR processing fee" on employee withholding beyond the tax itself. Penalties for late employer remittance are employer liabilities, though chronic under-withholding can affect employee ITR outcomes.

Example: ₱30,000/month earner

Consider an employee with ₱30,000 gross monthly salary, no large taxable bonuses yet, and standard mandatory deductions. Rough employee shares: SSS ₱1,500, PhilHealth ₱750, Pag-IBIG ₱200 — total ₱2,450. Taxable compensation might land near ₱27,550 monthly depending on payroll treatment of allowances, or lower if some pay is non-taxable.

Annualized taxable income ≈ ₱27,550 × 12 = ₱330,600. Applying TRAIN: tax = 15% × (₱330,600 − ₱250,000) = 15% × ₱80,600 ≈ ₱12,090 annually, or about ₱1,008 monthly withholding. SweldoSense rounds payroll components differently and estimates total deductions near ₱4,750 on ₱30,000 gross — including tax — with net pay around ₱25,250. Your employer's exact buwis may differ slightly with rounding, mid-year adjustments, or non-taxable components.

At ₱20,000 gross, annualized taxable income may fall closer to or below the ₱250,000 threshold after deductions — many earners at that level see little or no withholding until bonuses push them over. That nonlinear jump explains why a "small" raise can produce a surprisingly large buwis increase: you may cross from exempt territory into the 15% band.

Common mistakes

• Multiplying gross salary by a flat tax rate. TRAIN is progressive and applied on annual taxable income, not gross alone.
• Ignoring the ₱250,000 exemption. Monthly gross above ~₱20,000 does not automatically mean maximum tax — deductions and annualization matter.
• Forgetting taxable bonuses. 13th month above ₱90,000 and performance bonuses spike withholding in release months.
• Confusing buwis with SSS or PhilHealth. Each line on the payslip serves a different agency and rule set.
• Assuming zero January withholding means zero annual tax. Payroll often resets annualization after raises or bonus events.
• Skipping Form 2316 review. Errors discovered only at ITR filing are harder to correct than catching YTD mismatches monthly.

Practical tips

• Use our salary comparison tool when evaluating offers — identical gross can yield different buwis if one employer structures more non-taxable allowances.
• Work backward from target take-home with the net pay calculator before negotiating raises.
• Read negotiate a raise using net pay — gross-focused negotiations hide TRAIN bracket effects.
• Track cumulative withholding on each payslip against projected annual tax — surprises shrink when you annualize monthly.
• File or verify ITR promptly after receiving Form 2316 to claim refunds or fix under-withholding.
• Cite BIR revenue regulations at bir.gov.ph when disputing employer withholding methodology.

Buod sa Tagalog

Ang buwis sa payslip ay withholding tax sa ilalim ng TRAIN Law (RA 10963). Ang unang ₱250,000 ng taxable income bawat taon ay exempt (0%). Ang susunod na bracket mula ₱250,001 hanggang ₱400,000 ay may 15% tax sa excess over ₱250,000. Karaniwang hindi kasama sa taxable income ang SSS, PhilHealth, at Pag-IBIG kung tama ang payroll. Ang unang ₱90,000 ng 13th month ay tax-exempt. Gamitin ang salary calculator, net pay calculator, o compare tool para tantiyahin ang buwis, at i-verify sa bir.gov.ph.

Conclusion

TRAIN Law withholding tax — buwis on your payslip — follows graduated annual brackets with a ₱250,000 zero-tax threshold and 15% on the next ₱150,000 of taxable income. Monthly deductions are projections of annual liability, shaped by mandatory contribution exclusions, bonuses, and payroll annualization methods. Cross-check payslip amounts with BIR tables, reconcile Form 2316 at year-end, and use SweldoSense salary, net pay, and comparison tools to see how tax interacts with SSS, PhilHealth, and Pag-IBIG on your actual sweldo.
