Tax Criminal Act Violations Lawyer | Understanding the Criminal Side of a Tax Problem
The Punishment of Tax Evaders Act (조세범처벌법) criminalizes conduct such as evading tax through fraudulent means, issuing or receiving fake tax invoices, and failing to pay withheld taxes. Unlike a simple tax assessment, these cases can lead to a criminal referral, prosecution, and imprisonment or a fine in addition to the tax already owed. Because the National Tax Service and the prosecution service both get involved, a person under investigation is often dealing with an administrative reassessment and a criminal case at the same time, and decisions made in one track can affect the other.
Tax Criminal Act Violations | What Counts as a Tax Crime Under the Act
The Punishment of Tax Evaders Act lists specific categories of conduct. Which category applies changes the potential penalty and whether a referral to prosecutors is likely at all.
This covers using deceptive methods, such as double bookkeping, falsified contracts, or hidden income, to evade tax that would otherwise be due. Simple underreporting or an honest mistake in a tax return is normally handled as a civil reassessment with penalty tax, not a crime, unless active concealment is shown (조세범처벌법 제3조). Whether the method used counts as 'fraudulent or other unlawful means' is usually the central factual dispute.
It is a separate offense to issue a tax invoice without an actual transaction, or to receive one and use it to claim an input tax credit or inflate expenses (조세범처벌법 제10조). This is common in construction, staffing, and scrap-metal industries where paper transactions are used to generate deductible costs. The scale of the false invoice amount is often the key factor prosecutors weigh in deciding whether to indict.
An employer who withholds income tax or other taxes from payments to employees or contractors but does not remit it to the tax authority can face criminal liability, separate from the civil obligation to pay the withheld amount (조세범처벌법 제13조). Cash-flow problems at a company are a common backdrop, but they do not automatically excuse the failure to remit.
Where the evaded amount reaches certain statutory thresholds, the case can also be prosecuted under the Act on the Aggravated Punishment of Specific Crimes rather than the Punishment of Tax Evaders Act alone, which raises the applicable sentencing range considerably. The amount evaded within a single tax year is calculated cumulatively for this purpose.
A Civil Reassessment Is Not Automatically a Crime
Most tax disputes are resolved through an administrative reassessment and objection or appeal, without any criminal referral. A referral to the prosecution typically happens where the tax office finds evidence of intentional, active concealment rather than a reporting error, so how the case is framed at the audit stage matters.
Tax Criminal Act Violations | How the Administrative and Criminal Tracks Interact
A tax crime case rarely proceeds on only one track. Understanding how the National Tax Service, the police, and the prosecution divide responsibility helps in planning a defense.
Who Investigates First
Most tax criminal cases begin with a regular or special tax audit conducted by the National Tax Service or a regional tax office, not with a police investigation. If the auditor believes the conduct meets the threshold for a criminal referral, the case is forwarded to the prosecution as a 'tax offense complaint' (조세범처벌법 제21조), and only then does a criminal investigation formally start.
Statements Made During the Audit Can Follow You
Answers given during the tax audit, and documents voluntarily submitted at that stage, often become part of the case file once a criminal referral is made. Because of this, how a taxpayer responds to an audit request for materials or an interview can materially affect the later criminal case, even before any criminal referral has been decided.
The Tax Assessment Still Proceeds Separately
Even if a criminal case is dropped or ends in acquittal, the underlying tax assessment and any additional penalty tax generally remain in place unless separately challenged through an objection, a request for pre-assessment review, or a tax tribunal appeal. The two proceedings run on different statutory timelines and are not automatically resolved together.
Tax Criminal Act Violations | Defending a Tax Evasion Allegation
The core question in most tax evasion cases is not whether tax was underpaid, but whether the underpayment was achieved through 'fraudulent or other unlawful means' as required by the statute.
Distinguishing Evasion From a Reporting Error
Courts have generally required some form of active concealment — such as maintaining a second set of books, using another person's name for accounts, or destroying records — before conduct rises to the level of tax evasion under the Act (조세범처벌법 제3조). A defense often focuses on showing the underreporting resulted from a difference in legal interpretation or an accounting mistake rather than concealment.
Calculating the Amount Evaded
The amount treated as 'evaded' for sentencing purposes is not simply the additional tax assessed; it depends on how the tax base is recalculated, and disputes over depreciation, expense recognition, or valuation can significantly change that figure. Challenging the tax office's calculation methodology is frequently as important as challenging whether a crime occurred at all.
Corporate Liability and the Responsible Individual
Where the taxpayer is a corporation, the Act allows both the company and the individual who actually committed the violation — often a representative director or the person handling the accounting — to be punished (조세범처벌법 제18조). Identifying who within the company actually directed the concealment is often a contested issue, especially where responsibility is disputed among multiple officers.
Tax Criminal Act Violations | Fake Tax Invoice Cases
Fake or 'paper' tax invoice cases are prosecuted frequently because the invoice amount is easy to quantify and often involves multiple parties across a supply chain.
Issuing Side vs. Receiving Side
A person who issues an invoice for a transaction that did not occur, and a person who knowingly receives and uses that invoice to reduce their own tax liability, can both be charged under the same provision (조세범처벌법 제10조). Whether the receiving party knew or should have known the transaction was fictitious is frequently the central factual issue, particularly in multi-tier subcontracting structures.
Aggregate Invoice Value Drives Severity
Sentencing in fake invoice cases tends to track the total value of the false invoices issued or received, cumulated across the relevant period, rather than any single transaction. This means a defense strategy sometimes focuses on excluding certain invoices from the aggregate total by showing an underlying transaction did in fact exist, even if paperwork was irregular.
Tax Criminal Act Violations | Voluntary Disclosure and Reduction of Penalties
The tax system provides several mechanisms that can reduce penalty tax or influence a prosecutor's charging decision if a taxpayer comes forward before being caught.
Amended Return Before an Audit Notice
Filing an amended or supplementary return before receiving any notice of a tax audit can reduce the additional penalty tax that would otherwise apply, and this correction is also a relevant factor if the matter is later reviewed for a criminal referral (국세기본법 제48조). This is generally the most effective point at which to act if irregularities are discovered internally.
Cooperation After a Referral Is Made
Once a case has already been referred to the prosecution, full and prompt payment of the assessed tax, along with cooperation during the investigation, is often considered by prosecutors when deciding whether to pursue an indictment or seek a summary disposition rather than a formal trial. This is a matter of prosecutorial discretion rather than a fixed statutory reduction, so outcomes vary by case.
Interaction With Related Corporate Officers
In cases involving multiple company officers or a chain of subcontractors, disclosure by one party can shift exposure toward others in the same transaction chain. Coordinating a disclosure strategy requires care where several people connected to the same set of invoices or filings may be investigated separately.
⚠ Disclosure Timing Affects the Benefit Available
The reduction available through voluntary correction or amended filing decreases the longer a taxpayer waits, and no reduction is available once a tax audit notice has already been issued for the relevant period (국세기본법 제48조). Once a criminal referral has been made, disclosure no longer functions as a pre-audit correction and instead becomes a matter for negotiation with the prosecution.
Tax Criminal Act Violations | From Tax Audit to Resolution of the Criminal Case
We review the tax audit notice, any materials already submitted to the tax office, and the accounting records at issue to assess whether the facts support a criminal evasion or fake invoice charge, or whether the matter should remain purely administrative.
If the audit is still ongoing, we advise on what to submit and how to respond to interview requests, since statements and documents provided at this stage often become the basis of any later criminal referral.
Where irregularities are confirmed, we evaluate whether filing an amended return or making a voluntary correction before an audit notice issues can reduce penalty tax exposure and improve the client's position if a referral is later considered.
If the case is referred to the prosecution, we prepare a written opinion addressing the elements of the offense — particularly whether 'fraudulent or other unlawful means' is present — and attend investigative interviews.
Depending on the amount involved and the client's cooperation, the case may proceed by summary indictment, negotiated disposition, or full trial; we prepare sentencing materials addressing tax payment status and any voluntary correction made.
Separately from the criminal case, we assist with objections, pre-assessment review requests, or tax tribunal appeals challenging the underlying tax assessment, since resolving the criminal matter does not by itself resolve the tax liability.
Tax Criminal Act Violations | How Fees Are Determined
The retainer generally reflects which stage the case is at — pre-referral audit response, investigation-stage representation, or trial defense — and the complexity of the accounting issues involved, since tax criminal cases often require reviewing extensive financial records.
Where a success fee structure applies, it is discussed in advance and tied to a clearly defined, objective outcome (such as a non-indictment decision or a specific disposition), consistent with applicable attorney advertising rules; no particular result can be promised in advance.
Because these cases involve both legal and tax-accounting issues, fees may also reflect coordination with a tax accountant or forensic accountant retained to analyze the tax base calculation, and this cost is discussed separately from the attorney fee.
Actual expenses such as document copying, expert opinion fees, and travel for regional tax office or court appearances are billed separately as incurred.

Tax Criminal Act Violations | Self-Check Before Your Consultation
1️⃣ Are You Still at the Audit Stage?
- Has the tax office issued a formal audit notice, or is this only an informal information request?
- Have you already submitted documents or given a statement to the auditor?
- Does the audit notice mention a specific tax year and specific transactions, or is it a general review?
- Has more than one tax year been flagged?
2️⃣ Tax Evasion Specific Checks
- Did you keep a second set of books, use another person's name for an account, or destroy any records?
- Was the underreporting due to a difference in legal interpretation (e.g., expense classification) rather than concealment?
- Do you have documentation showing the original transaction actually occurred?
- Has the tax office calculated a specific 'evaded amount,' and do you understand how it was derived?
3️⃣ Fake Tax Invoice Specific Checks
- Did the underlying transaction actually take place, even if some paperwork was irregular?
- Were you the one who issued the invoice, or did you receive it from another party?
- Do you have evidence of payment, delivery, or performance connected to the invoice?
- How many invoices and what total amount is at issue across the audit period?
4️⃣ Disclosure and Timing
- Have you already received a tax audit notice for the period in question? (This affects whether a voluntary correction reduction is still available.)
- Has the case already been referred to the prosecution, or is it still within the tax office?
- Are other individuals (co-directors, business partners) connected to the same transactions also under review?
- Have you already paid, or can you pay, the assessed tax amount?
