In the Philippine legal landscape, the power to tax is considered the "lifeblood" of the government. Consequently, the state treats any attempt to subvert the collection of taxes with significant gravity. Tax evasion is not merely a civil matter of unpaid debt; it is a criminal offense defined under the National Internal Revenue Code (NIRC) of 1997, as amended by subsequent laws such as the TRAIN Law (R.A. 10963).

Tax Evasion vs. Tax Avoidance: The Legal Distinction

Before delving into penalties, it is crucial to distinguish between legal tax planning and criminal evasion.

Tax Avoidance: This is the legal use of the tax regime to one's advantage to reduce the amount of tax that is payable by means that are within the law. Examples include claiming legitimate deductions or choosing a business structure with lower tax rates.
Tax Evasion: This is the illegal failure to pay taxes. it involves the use of fraud, deceit, or concealment to minimize tax liability.

Key Provisions Under the Tax Code

The NIRC outlines several specific acts that constitute criminal violations. The most prominent sections include:

1. Section 254: Attempt to Evade or Defeat Tax

Commonly known as the "Tax Evasion" provision, it penalizes any person who willfully attempts in any manner to evade or defeat any tax imposed under the Code or the payment thereof.

2. Section 255: Failure to File Return or Pay Tax

This section punishes the willful failure to:

Pay the tax due.
Make a return.
Keep required records.
Supply correct and accurate information.

3. Section 248: Civil Fraud

While not a criminal penalty per se, Section 248 imposes a 50% surcharge on the tax due in cases of "willful neglect" or "intent to evade tax" through false or fraudulent returns.

Elements of Tax Evasion

For a criminal conviction of tax evasion to prosper, the prosecution must prove three essential elements beyond reasonable doubt:

An amount of tax due and owing: There must be an actual underpayment or non-payment of a valid tax.
Willfulness: The taxpayer must have intentionally and voluntarily violated a known legal duty. Negligence or honest mistakes do not constitute criminal evasion.
Affirmative Act: There must be an "affirmative act" constituting evasion, such as keeping a double set of books, making false entries in records, or concealing assets.

Penalties and Sanctions

The Philippine government has significantly increased the penalties for tax-related crimes to serve as a deterrent.

Criminal Penalties (Section 254)

Under the current laws (TRAIN Law amendments), any person convicted of attempting to evade or defeat tax shall be punished by:

Fine: Not less than P500,000 but not more than P10,000,000; and
Imprisonment: Not less than six (6) years but not more than ten (10) years.

Penalties for Corporations

When the offender is a corporation, the penalty is imposed upon the officers responsible for the violation (e.g., President, General Manager, Treasurer, or the CPA who signed the return). Additionally, the corporation may be fined and its license to do business revoked.

Civil Penalties

Criminal prosecution for tax evasion is independent of the civil obligation to pay the tax. Even if acquitted of the criminal charge (unless the acquittal is based on the finding that the tax was not due), the taxpayer must still pay:

The Basic Tax due.
50% Surcharge (for fraud/intent to evade).
Deficiency Interest (currently 12% per annum under the TRAIN Law).

The "Run After Tax Evaders" (RATE) Program

The Bureau of Internal Revenue (BIR), in coordination with the Department of Justice (DOJ), operates the RATE Program. This initiative focuses on investigating and prosecuting high-profile individuals and corporations suspected of tax evasion.

The Judicial Process

Investigation: The BIR conducts a preliminary investigation and issues a Letter of Authority (LOA).
Filing of Complaint: If fraud is detected, a criminal complaint is filed with the DOJ.
Probable Cause: If the DOJ finds probable cause, an Information is filed in court.
Jurisdiction: Cases involving an assessed tax liability of P1 million or more (exclusive of interests and penalties) fall under the jurisdiction of the Court of Tax Appeals (CTA). Smaller amounts are handled by the regular Trial Courts.

Common Schemes Constituting Evasion

Under-declaration of Income: Deliberately reporting less revenue than actually earned.
Overstatement of Expenses: Claiming fictitious deductions or personal expenses as business expenses.
Use of "Ghost" Receipts: Using fake invoices from non-existent suppliers to inflate input VAT or deductible expenses.
Non-remittance of Withholding Taxes: Collecting taxes from employees but failing to remit them to the BIR.

Note on Prescription: The prescriptive period for the government to collect taxes is generally three (3) years from the filing of the return. However, in cases of fraud or intent to evade tax, the prescriptive period is extended to ten (10) years from the discovery of the fraud.
