Legal Consequences of Using an Unverified Tax Identification Number (TIN) in Employment
Philippine Context
Disclaimer – This article is for general information only and is not legal advice. Tax and labor rules change; consult a Philippine lawyer or certified tax professional for guidance on specific situations.
1 | Why TIN Verification Matters
The Tax Identification Number is the employee’s unique identifier in all dealings with the Bureau of Internal Revenue (BIR).
- Payroll Withholding. Employers remit monthly compensation taxes to the BIR using each worker’s TIN.
- Annual Information Returns (BIR Form 1604‑C, Alphalist). The BIR’s electronic matching system rejects mismatched or duplicate TINs, delaying clearance of the employer’s entire payroll.
- Social security & banking tie‑ins. PhilHealth, SSS, Pag‑IBIG and most local banks cross‑reference TINs when evaluating benefits, loans and anti‑money‑laundering checks.
An “unverified” TIN typically means a number that:
| Scenario | Typical cause |
|---|---|
| Fake / fabricated | Worker was never registered with the BIR. |
| Duplicated | Employee once obtained a second TIN (a criminal offense). |
| Incorrectly keyed | HR or employee mistyped digits during hiring. |
2 | Statutory & Regulatory Framework
| Source | Key provision |
|---|---|
| National Internal Revenue Code (NIRC) of 1997 (as amended) | §236 (E) – Every person subject to any internal‑revenue tax must secure a TIN. §255–§257 – Fines & imprisonment for failure to file returns or for willful falsehoods. |
| Revenue Regulations (RR) No. 11‑2013 | Mandates one TIN per taxpayer for life; obtaining multiple TINs or using a fictitious one is penalized. |
| Revenue Memorandum Circulars (e.g., RMC 67‑2012, 97‑2016) | Require employers to validate TINs through the BIR’s eTIN or TIN Inquiry Facility before payroll enrollment. |
| Labor Code, Art. 116 | Makes it unlawful for any person “to obstruct or interfere with the right of any employee” under labor standards, including correct tax withholding. |
| Revised Penal Code, Art. 172 | Falsification of public documents (e.g., BIR forms) carries imprisonment and fines. |
| Data Privacy Act of 2012 (RA 10173) | Mishandling personal data—such as using another person’s TIN—opens employers to administrative fines and civil damages. |
3 | Liability of the Employee
Administrative penalties (BIR).
- Compromise penalty ₱1,000 – ₱25,000 for first‑time offenders who voluntarily disclose.
Criminal penalty (NIRC §257).
- Fine ₱10,000 – ₱50,000 and/or
- Imprisonment 6 months – 5 years for willful use of a fake or multiple TINs.
Revised Penal Code falsification charges if the worker knowingly signs BIR Form 1902/1905 with false data.
Employment sanctions. An untrue TIN may constitute serious misconduct or fraud, a just cause for dismissal under Labor Code Art. 297.
Civil liability. The employer may sue to recover penalties and interest it paid because of the false TIN.
4 | Liability of the Employer / HR Manager
| Violation | Possible Sanctions |
|---|---|
| Failure to withhold or remit correct tax (NIRC §255) | Surcharge 25 %–50 % of tax + interest 12 % p.a. + compromise penalty up to ₱50,000 per return. |
| Aiding or abetting the use of a false TIN (NIRC §257) | Fine ₱50,000 – ₱100,000 and/or imprisonment 2–6 years. |
| Submission of false Alphalist | BIR rejects filing; CSR/BIR Clearance is withheld; possible suspension of eFPS enrollment. |
| Data‑privacy breach | NPC may impose fines up to ₱5 million plus damages. |
| Labor‑standard effect | DOLE may cite employer for technical wage violations if net‑of‑tax pay is wrong. |
Key point: Even if the employee supplied the fake TIN, the employer remains primarily liable for deficient withholding. The BIR doctrine is “employer as withholding agent bears the risk.”
5 | Procedural Consequences
- BIR Audit Trigger – Mismatched TINs often generate a Letter of Authority (LOA) or Notice for Data Reconciliation.
- Assessment & Collection – Deficiencies are assessed against the employer; BIR may garnish bank accounts if unpaid.
- Delayed Tax Clearance – Companies bidding for government projects need a BIR Certificate of No Outstanding Liability; unresolved TIN issues stall issuance.
- Certification Holds – Employees cannot secure BIR Form 2316 or 2305, blocking visa applications, bank loans and Pag‑IBIG housing loans.
6 | Corrective Actions & Mitigation
| Step | Practical Tips |
|---|---|
| Pre‑employment TIN validation | Use BIR’s eREG/TIN Verification website or call the BIR Contact Center (landline 8‑981‑8888). |
| One‑time TIN registration drives | Coordinate with BIR District Offices to bulk‑process new hires (BIR Form 1902). |
| Sworn Declaration from employee | Require a notarized statement that the submitted TIN is the only TIN ever issued. |
| HRIS integration | Configure payroll software to reject non‑14‑digit TINs or duplicates. |
| Voluntary Disclosure Program (VDP) | If unverified TINs are discovered, file under the BIR’s VDP to reduce surcharges. |
| Data‑privacy safeguards | Limit TIN access to payroll personnel, encrypt in storage, purge old HR files. |
| Internal disciplinary policy | Classify falsification of government IDs as a terminable offense; ensure due‑process procedures (notice & hearing). |
7 | Illustrative Cases
| Year / Citation | Highlight |
|---|---|
| BIR v. Jeofrey Go (CTA Case No. 9216, 2019) | Employer assessed for ₱3.2 M deficiency because 12 employees had duplicate TINs; court upheld BIR, noting employer “was in the best position to validate.” |
| People v. Reyno (RTC Davao, 2017) | Employee convicted under NIRC §257 for using fictitious TIN to avoid withholding; sentenced to 1 yr 8 mos prison, ₱20 k fine. |
| NPC Advisory Opinion 2018‑043 | Misuse of someone else’s TIN is “unauthorized processing of personal data,” actionable under RA 10173. |

8 | Best‑Practice Checklist for Employers
- Require government‑issued IDs (e.g., PhilSys, passport) that show the TIN or cross‑validate name + birthdate with BIR.
- Maintain a TIN Validation Log signed by payroll staff.
- Embed two‑factor verification (TIN + RDO code) in onboarding workflow.
- Conduct quarterly payroll compliance reviews covering TIN status, Alphalist error reports, and BIR eFPS acknowledgments.
- Keep documented proof of due diligence (screenshots, BIR email confirmations) to defend against BIR audits.
9 | Takeaways
- Zero tolerance – A single unverified TIN can cascade into tax assessments and criminal exposure.
- Employer on the hook – The BIR treats the company as guarantor for correct withholding; “we relied on the employee” is not a defense.
- Prevention cheapest – eTIN validation, clear HR policies and swift correction through the BIR’s VDP cost far less than surcharges and litigation.
Need tailored advice?
If you discover unverified TINs in your workforce, engage (a) your company’s tax counsel for immediate rectification with the BIR, and (b) an HR lawyer to align disciplinary processes with due‑process requirements under the Labor Code and DO 174‑17.
