How BIR Coordinates With DOJ in Tax Criminal Investigations in the Philippines

Executive Summary

Not every BIR audit becomes a criminal case.

Most tax examinations remain administrative or civil matters involving tax assessments, unpaid taxes, documentation issues, or disputed deductions. However, when the Bureau of Internal Revenue believes the evidence points to a possible criminal violation of the Tax Code, the case may be referred or filed with the Department of Justice (DOJ) for prosecutorial evaluation.

The BIR is primarily responsible for administering and enforcing the National Internal Revenue Code, while the DOJ’s National Prosecution Service has the principal role in the preliminary investigation and prosecution of criminal offenses. The Supreme Court has recognized these complementary functions.

Recent DOJ cases involving alleged fake or fictitious receipts show how this coordination works in practice: the BIR investigates and builds the tax case, files a criminal complaint, and prosecutors evaluate whether the evidence supports filing criminal informations in court.

What Is the BIR’s Role in a Criminal Tax Investigation?

The BIR usually develops the tax side of the case.

Depending on the alleged violation, investigators may review tax returns, books of accounts, invoices, purchases, sales, withholding records, contracts, accounting entries, and other documents.

The BIR may also investigate suspected tax evasion through enforcement programs aimed at serious violations. Its RATE complaint mechanism states that complaints are reviewed, classified, and referred to the appropriate investigating office for action.

The purpose is to determine whether the evidence suggests more than an ordinary tax deficiency.

For example, investigators may look for signs of deliberate conduct such as concealed income, fictitious purchases, false invoices, or intentional misstatements in tax returns.

When Does the DOJ Become Involved?

The DOJ becomes particularly important once the case moves toward criminal prosecution.

Under the National Prosecution Service framework, prosecutors are primarily responsible for conducting preliminary investigations and prosecuting violations of penal laws. The Supreme Court has explained that this authority operates alongside the BIR’s responsibility to enforce the penal provisions of the Tax Code.

In practical terms, the process may look like this:

BIR investigation → evidence gathering → approval and filing of criminal complaint → DOJ or prosecutor evaluation → filing of Information in court if the evidentiary standard is met.

This does not mean the DOJ merely approves whatever the BIR submits.

Prosecutors independently evaluate whether the evidence and applicable law justify criminal prosecution.

Why Is the Commissioner of Internal Revenue Important?

Criminal tax cases cannot simply be initiated in court by any BIR employee.

Section 220 of the National Internal Revenue Code provides that civil or criminal actions for the recovery of taxes or enforcement of penalties under the Code cannot be filed in court without the approval of the Commissioner of Internal Revenue.

DOJ requirements for complaints involving violations of the National Internal Revenue Code likewise identify an Authority to File Complaint signed by the Commissioner of Internal Revenue as a required document for preliminary investigation.

The Supreme Court has also recognized that the Commissioner’s express approval may accompany the referral of a tax case for preliminary investigation and court filing if the evidence warrants prosecution.

What Does the BIR Usually Submit to Prosecutors?

A criminal complaint generally needs evidence supporting the alleged offense.

Depending on the case, the submission may include complaint-affidavits, investigation findings, tax returns, accounting records, invoices, transaction documents, certifications, computations, and other supporting evidence.

DOJ preliminary investigation procedures require a complaint-affidavit or sworn statement and supporting documents, together with the required authority for NIRC cases.

The strength and consistency of this evidence matter because prosecutors must evaluate whether criminal proceedings should continue.

What Does the DOJ Evaluate?

The DOJ does not simply determine whether a taxpayer owes additional tax.

The issue in a criminal investigation is whether the available evidence supports an alleged criminal tax offense and whether prosecution is justified.

Recent DOJ announcements describe prosecutors reviewing BIR evidence before criminal informations were filed against corporations and responsible officers for alleged violations involving tax evasion and false information.

For business owners, this distinction is important.

A difference in tax computation is not automatically proof of criminal intent.

Prosecutors must consider the specific offense, the evidence, the participation of the respondents, and the applicable legal requirements.

How the Process Works in Practice

Consider a business that claims substantial purchases and deductions.

During investigation, the BIR discovers evidence suggesting that some invoices came from companies with no genuine business operations.

Investigators may examine whether goods or services were actually delivered, how payments were made, who approved the transactions, and whether the expenses were used to reduce taxable income.

If the BIR concludes that the evidence supports possible criminal violations, it may file a complaint for preliminary investigation.

The DOJ then evaluates the evidence.

A real example involved a cosmetics company investigated under the BIR’s Run After Fake Transactions program. The BIR filed a criminal complaint with the DOJ in February 2024. After the DOJ’s own evaluation, criminal informations were filed in court in March 2025 against the corporation and responsible officers.

Another DOJ case involving a construction corporation similarly arose from a BIR complaint alleging fictitious transactions. Prosecutors later found sufficient evidence to file criminal charges for alleged violations of Sections 254 and 255 of the Tax Code.

BIR Investigation Is Not the Same as DOJ Prosecution

These stages should not be confused.

During a BIR investigation, the government may still be gathering records and determining whether a violation occurred.

Once a criminal complaint reaches prosecutors, the focus becomes whether the evidence supports prosecution under the applicable penal provisions.

And even when a criminal Information is eventually filed in court, the accused remains entitled to due process and the prosecution must still prove the criminal case under the applicable standard.

A BIR accusation therefore does not equal a criminal conviction.

Can Corporate Officers Be Included?

Yes, depending on the facts and the applicable Tax Code provisions.

Recent BIR-DOJ cases have involved both corporations and responsible corporate officers.

For example, DOJ announcements regarding alleged fictitious receipt schemes have identified presidents, treasurers, and other corporate officers as respondents or accused together with their companies.

However, corporate title alone does not mean every director or officer is automatically criminally liable.

The government must establish the legal and factual basis for charging the particular individual.

What Happens After the DOJ Finds Sufficient Basis?

If prosecutors determine that the evidence supports prosecution, criminal informations may be filed before the court with jurisdiction over the offense.

Recent cases show tax prosecutions being filed before the Court of Tax Appeals and, depending on the offense and circumstances, other proper courts.

At that point, the controversy has moved beyond an administrative tax investigation and into formal criminal litigation.

Can Other Law Enforcement Agencies Become Involved?

Yes.

Some tax investigations may involve other agencies when the alleged conduct extends beyond ordinary tax record review.

For example, a 2025 tax evasion case involving illicit cigarettes originated from a joint operation involving the BIR and the Criminal Investigation and Detection Group (CIDG).

The BIR later filed a complaint, prosecutors evaluated the evidence, and criminal Information was filed before the CTA.

Other cases involving fictitious receipts have also involved investigative work by the National Bureau of Investigation.

This illustrates that serious tax investigations can involve coordination among several government agencies.

What Should a Business Do If a Tax Investigation Appears Criminal?

Do not treat the matter as an ordinary accounting inquiry.

Management should identify the allegations, taxable periods, transactions involved, and responsible personnel.

Relevant records should be preserved immediately, including tax returns, invoices, contracts, payment records, emails, accounting entries, and corporate approvals.

The company should also review whether its explanations are consistent with its books and supporting documents.

Most importantly, do not alter, fabricate, backdate, or destroy records.

When the BIR is investigating suspected fraud, fictitious transactions, deliberate non-filing, or possible tax evasion, coordinated legal and tax advice becomes particularly important.

Common Mistakes During a BIR-DOJ Tax Investigation

One mistake is assuming that paying a tax deficiency will automatically end every possible criminal issue.

Another is responding to investigators without first understanding the underlying transactions.

Companies may also create unnecessary problems when different officers give inconsistent explanations, when documents do not match the accounting records, or when management assumes that an accountant alone should handle an investigation involving possible criminal liability.

Once a case has reached the prosecutorial stage, the issue is no longer limited to tax computation.

Practical BIR-DOJ Investigation Checklist

If your business is facing a serious tax investigation, review:

BIR notices and investigation documents → alleged Tax Code violations → taxable periods → transactions under investigation → books and supporting records → responsible officers → Commissioner approval or authority → complaint filed with prosecutors → preliminary investigation submissions → court developments.

Keep a complete record of every document submitted and every official communication received.

Frequently Asked Questions

Does every BIR audit go to the DOJ?

No.

Many audits remain administrative tax matters. DOJ involvement becomes relevant where the BIR pursues potential criminal violations.

Can the DOJ reject or decline to prosecute a BIR complaint?

The DOJ conducts its own prosecutorial evaluation. Filing a BIR complaint does not automatically guarantee that criminal Information will be filed in court. Recent DOJ announcements expressly describe prosecutors reviewing evidence before deciding to charge respondents.

Does the BIR Commissioner need to approve a criminal tax case?

Section 220 of the Tax Code requires the Commissioner’s approval before civil or criminal actions covered by the provision are filed in court. DOJ preliminary investigation requirements for NIRC violations also call for an Authority to File Complaint signed by the Commissioner.

Can both the corporation and its officers be prosecuted?

Potentially, yes. Recent cases have involved corporations together with responsible officers, depending on the alleged violation and evidence.

Is an unpaid tax automatically a criminal case?

No.

An unpaid tax may create civil liability without necessarily establishing a criminal offense. Criminal liability depends on the specific Tax Code violation and the evidence supporting the required elements.

Final Thoughts

The BIR and DOJ perform different but connected roles in Philippine criminal tax enforcement.

The BIR generally investigates the tax transactions, gathers records, identifies possible violations, and initiates the criminal complaint.

The DOJ and its prosecutors evaluate whether the evidence supports criminal prosecution and, when appropriate, file criminal informations before the proper court.

For businesses, the important warning sign is when a tax examination stops focusing only on computations and begins examining alleged intentional conduct, fictitious transactions, false returns, or the personal involvement of corporate officers.

At that stage, careful legal and tax review becomes critical.

A BIR investigation may identify the alleged tax violation. The DOJ determines whether the evidence should move forward as a criminal prosecution.
