Korean Tax-Crime Investigation Total Exposure Calculator

Separate a Korean tax-crime investigation into administrative principal and penalties, a notice or criminal-fine scenario, confirmed forfeiture or collection, professional and business-interruption costs, and temporarily locked liquidity. The dedicated calculator reuses the full Korean pure calculation engine, flags only numerical Article 3 and Special Act Article 8 review bands, and reports economic exposure, total liquidity required, and the gap against available cash without predicting guilt, applicable law, a notice disposition, dual liability, or a sentence.

Step 1 · Administrative tax

Additional tax and amounts already paid

Copy principal tax and penalties from the audit worksheet or amended-return draft. This tool does not redetermine penalty rates.

Step 2 · Fine scenario

Evaded-tax base and confirmed multiplier

Numerical bands are review signals only. They do not determine intent, counts, applicable law, guilt, or sentence.

Step 3 · Criminal property exposure

Confirmed forfeiture and collection range

This tool does not calculate whether forfeiture or collection applies. Enter only a range supported by documents or counsel.

Step 4 · Response and operating costs

Professional fees and interruption loss

Use engagement quotes and an internal monthly-loss estimate. Do not put recoverable deposits in this bucket.

Step 5 · Liquidity

Locked funds and available cash

Replacement cash and locked collateral may be needed temporarily, but are shown separately from economic loss.

Items requiring confirmation

  • Frozen-account replacement cash and locked collateral are added to liquidity needs, not economic loss.

What to do with this result

  1. Ask the tax adviser to reconcile principal tax, penalties, credits, and the evaded-tax fine base to the source documents.
  2. Ask criminal counsel to confirm the applicable article, violation count, liable subjects, and forfeiture/collection range separately.
  3. Have treasury separate economic exposure from locked funds in 30-day and 90-day cash plans.

Why separate the total exposure into four ledgers?

A Korean tax-crime investigation can create several cash demands at once: assessed principal tax, administrative penalties, a notice-disposition amount or criminal fine scenario, forfeiture or collection, professional fees, and disruption to the business.
Treating all of those amounts as one tax assessment can double-count payments already made, mistake recoverable collateral for a permanent loss, or omit separate exposure for an actor and an entity.
This calculator therefore separates administrative tax, criminal property exposure, response and operating costs, and liquidity that is merely locked.
It then reports economic exposure and total liquidity required as two different ranges.
The result does not predict intent, guilt, the number of offenses, dual liability, the availability of a notice disposition, or a court sentence.

Economic exposure

This includes unpaid administrative tax, the selected fine range, a separately confirmed forfeiture or collection range, and non-recoverable response and operating costs.
It is the current estimate of potential spending or loss under the assumptions entered.

Total liquidity required

This adds frozen-account replacement cash and locked collateral or guarantee cash to economic exposure.
Locked principal is not classified as a loss, but the business may still need substitute cash while it is unavailable.

Critical scope: every statutory amount and percentage shown here is a numerical review signal.
Applicable law, annual aggregation, violation history, liable subjects, aggravation, and mitigation require case-specific professional confirmation.

The four ledgers and formulas

1. Administrative-tax ledger

Add principal tax, non-filing or underreporting penalties, late-payment penalties, and other administrative charges, then subtract amounts already paid or credited.
The calculator accepts confirmed or estimated amounts rather than redetermining rates and elapsed days under the Framework Act on National Taxes.

Remaining administrative tax = principal + filing penalty + late penalty + other charges - paid or credited amount

2. Criminal-property ledger

Multiply the confirmed evaded-tax base by a selected notice, statutory stress, or adviser-confirmed multiplier and by the number of confirmed subjects.
Then add a forfeiture or collection range supported by documents or counsel.
Notice-table scenarios discard amounts below KRW 10, while other stress scenarios round to the nearest won.

Criminal property exposure = evaded-tax base x confirmed multiplier x subjects + confirmed forfeiture or collection

3. Response and operating-cost ledger

Add criminal defense, tax representation, forensic accounting or data recovery, monthly interruption loss multiplied by affected months, and other non-recoverable costs.
Use written quotes with aligned VAT, expenses, attendance, investigation, and trial scopes rather than an assumed market average.

4. Locked-liquidity ledger

Replacement cash for restricted accounts and principal locked as collateral are excluded from economic loss and included only in total liquidity required.
Non-recoverable guarantee fees, interest, and setup charges belong in other response costs instead.

2026 fine and notice-disposition scenarios

Article 3(1) of the Punishment of Tax Offenses Act provides a fine ceiling of up to two times the evaded or improperly refunded tax under its main clause.
Its proviso provides an up-to-three-times ceiling when the amount is at least KRW 300 million and at least 30% of the tax due, or when the amount is at least KRW 500 million.
Article 8 of the Act on the Aggravated Punishment of Specific Crimes addresses annual evaded-tax bands beginning at KRW 500 million and adds a fine range of two to five times the amount.
It provides life imprisonment or at least five years when annual evaded tax is KRW 1b or more, and at least three years for KRW 500 million to below KRW 1b, but this calculator does not convert imprisonment into money.
These provisions are not automatic classifications produced by the calculator.

Why the base notice table is not a final amount

The Enforcement Decree table connects violation history with case-specific aggravating and mitigating factors, statutory caps, and a rule that discards amounts below KRW 10.
Articles 13, 15, and 17 of the Procedure for the Punishment of Tax Offenses Act also distinguish notice disposition, accusation, and no-suspicion outcomes and address noncompliance with a notice.
A table multiplier is therefore only a planning starting point and does not guarantee a procedural route or final criminal outcome.

How to prepare the inputs

  1. Choose one as-of date. Align every amount to the audit result date, amended-return review date, or notice receipt date.
  2. Reconcile administrative tax. Match principal, each penalty, and paid amounts to assessment or payment records, and keep them separate from the criminal fine base.
  3. Confirm the criminal-law basis in writing. Identify the article, main clause or proviso, three-year violation count, annual aggregation, liable subjects, and present procedural stage.
  4. Enter forfeiture as a range. Leave it at zero without support, and otherwise use only a low and high amount confirmed in documents or by counsel.
  5. Align quote scopes. Compare VAT, expenses, written opinions, attendance, accusation-stage investigation, and trial work on the same basis.
  6. Build two cash schedules. Keep non-recoverable spending separate from temporarily locked cash for 30-day and 90-day planning.

Worked example

The default example enters KRW 100 million of principal tax, KRW 40 million of filing penalties, KRW 8 million of late-payment penalties, and KRW 10 million already paid, leaving KRW 138 million of administrative tax.
A KRW 100 million evaded-tax base under the first main-clause notice-table scenario produces a KRW 50 million fine sensitivity.
Forfeiture or collection is set from zero to KRW 10 million, professional costs total KRW 35 million, three months of interruption cost KRW 30 million, and other non-recoverable cost is KRW 2 million.
Economic exposure is therefore KRW 255 million to KRW 265 million.
Adding KRW 30 million of frozen-account replacement cash and KRW 20 million of locked collateral produces a total liquidity need of KRW 305 million to KRW 315 million.
With KRW 150 million available, the liquidity gap is KRW 155 million to KRW 165 million.

Practical planning scenarios

First 30 days after notice of investigation

Enter assessed tax and contracted initial response work as confirmed amounts while keeping fine and forfeiture assumptions as a documented low-to-high range.
Discuss financing against the high liquidity gap rather than a single optimistic figure.

After receiving a notice disposition

Replace the base scenario with the fine-equivalent and forfeiture or collection amounts stated in the notice where applicable.
Confirm the compliance deadline and procedural consequences with counsel rather than deciding from the amount alone.

Entity and individual exposure

Before increasing the subject count under Article 18 dual-liability concerns, confirm the legal basis and the fine base for every person or entity.
The subject-count field only multiplies a confirmed identical scenario and does not decide who is liable.

Business-continuity meeting

Protect essential payroll, purchasing, and rent for the next 90 days before allocating company operating cash to an individual exposure.
Add borrowing interest and non-refundable guarantee costs after confirming how and when locked funds can be released.

Frequently asked questions

Is evaded tax always the same as additional principal tax?

No.
Tax type, period, refunds or credits, offense counts, and the legal definition of evaded tax can create differences, so reconcile both amounts to their source documents.

Does reaching KRW 500 million automatically apply the Special Act?

No.
The calculator only flags a numerical band and does not determine annual aggregation, offense elements, or the applicable charging provision.

Is the 0.5x first-violation value the final notice amount?

No.
The base table is connected to case-specific adjustments, caps, and rounding rules, so an actual notice or reviewed case-specific value takes priority.

Should collateral principal be counted as a loss?

If principal is expected to be returned, keep it in locked liquidity rather than economic exposure.
Put non-refundable fees, interest, setup charges, or actual impairment in the non-recoverable cost bucket.

Can this result be filed as a legal opinion or court exhibit?

This is a user-input sensitivity worksheet, not an official assessment, valuation, legal opinion, or sentencing submission.
For formal use, have the underlying documents and assumptions verified in a separate professional work product.

Primary legal sources and verification date

The Korean statutory sources were checked in the National Law Information Center on August 30, 2026.
The review used law ID 001583 and master sequence 224875 for Articles 3 and 18 of the Punishment of Tax Offenses Act, and law ID 001676 and master sequence 270397 for Article 8 of the Act on the Aggravated Punishment of Specific Crimes.
It used law ID 000641 and master sequence 247789 for Articles 13, 15, and 17 of the Procedure for the Punishment of Tax Offenses Act.
The notice-table review used law ID 004914, master sequence 283663, and annex ID 17991709 of its Enforcement Decree.
Administrative penalty context was checked against Articles 47-2 through 47-4 of the Framework Act on National Taxes, law ID 001586 and master sequence 288571, although the calculator accepts user-supplied amounts.

Recheck the law in force on the actual decision date together with the notice, accusation documents, and guidance from the competent authority.

Next action

Print the result as four rows and write the supporting document and reviewer beside every number.
Ask the tax adviser to reconcile principal, penalties, payments, and the evaded-tax base, then ask criminal counsel to review the provision, violation count, subjects, and forfeiture or collection range separately.
Finally, build 30-day and 90-day financing schedules from the liquidity gap without mixing recoverable collateral principal with permanent spending.

Start with a documented low case and high case instead of relying on one point estimate.
