What this Korea vehicle seizure and public auction calculator does
This calculator models what may happen when a vehicle seized for Korean national or local tax arrears is sold through a compulsory public auction. It starts with the initial reserve or appraised value, applies the statutory failed-auction reduction schedule, and compares the current reserve floor with an expected winning bid. It then allocates the planning sale proceeds across enforcement costs, verified senior claims, the arrears connected to the seizure, and verified subordinate claims.
The result shows the amount recovered at each step, arrears that may remain after the vehicle is sold, and any estimated balance that could be returned to the owner. It is designed for the debtor or vehicle owner, not for an investor buying a vehicle. It also differs from the separate seizure-release calculator, which estimates the amount needed to pay delinquent vehicle tax and fines before a sale.
Korea-specific jurisdiction note
This English page uses Republic of Korea rules verified as current on July 19, 2026. Amounts are in KRW. It does not determine legal priority, cancel a seizure, suspend a sale, or replace the collecting authority statement, vehicle register, attorney, judicial scrivener, or tax professional review.
The 2026 legal framework
The National Tax Collection Act governs compulsory collection for national taxes. The version checked through the National Law Information Center is current from June 2, 2026. The Local Tax Collection Act version used here is current from February 5, 2026. The National Framework Act on National Taxes is current from July 1, 2026, the Framework Act on Local Taxes from February 5, 2026, and the Motor Vehicle Management Act from June 16, 2026.
| Rule | Why it matters |
|---|
| National Tax Collection Act Articles 65 to 68 | Sale method and setting the public-auction reserve price. |
| National Tax Collection Act Article 87 | Each failed round reduces the initial reserve by 10%, down to a 50% floor. |
| National Tax Collection Act Articles 94 and 96 | Defines distributable money, eligible claims, and return of any remainder to the debtor. |
| Local Tax Collection Act Articles 91, 97, and 99 | Provides the corresponding local-tax re-auction and distribution structure. |
| National Framework Act Article 35 and Local Framework Act Article 71 | Requires priority analysis using statutory dates, lien registration, and special priority rules. |
| Motor Vehicle Management Act Articles 6, 12, and 14 | Vehicle ownership changes through registration and tax or court seizures are recorded. |
Under National Tax Collection Act Article 91 and Local Tax Collection Act Article 94, the purchaser acquires the property after paying the purchase price, and the authority treats the received price as collection from the debtor to that extent. A sale therefore does not automatically erase arrears greater than the amount actually distributed to them.
Failed-auction reserve formula
National Tax Collection Act Article 87 reduces each re-auction by an amount equal to 10% of the initial reserve, until the reserve reaches 50% of that initial amount. Local Tax Collection Act Article 91 uses the corresponding 10% step and 50% limit for local-tax dispositions. The calculator applies the following standard schedule.
Normalized failed rounds = clamp(floor(rounds), 0, 5)
Current ratio = max(50%, 100% − 10% × failed rounds)
Current reserve floor = initial reserve × current ratio
Applied planning proceeds = max(current reserve floor, entered expected bid)
The schedule is 100% for a new sale, 90% after one failed round, 80% after two, 70% after three, 60% after four, and 50% after five. For an initial reserve of KRW 20,000,000, two failed rounds produce a current floor of KRW 16,000,000. If the entered expected bid is KRW 14,000,000, the calculator uses KRW 16,000,000 because the entered amount is below the current reserve.
The model does not continue reducing below 50%. After the statutory schedule is exhausted, the authority may arrange a new appraisal or reserve, or consider a private contract when the legal conditions are met. A private sale is possible in specified cases, including an estimated value below KRW 10,000,000 or repeated failure, but it is not automatic.
How to prepare each input
Initial reserve or appraised value
Use the value in the official public-auction notice or appraisal, not a retail used-car advertisement. Vehicle condition, keys, documents, storage, accident history, and access can affect the actual bid.
Enforcement and public-sale costs
Enter the current case amount for towing, storage, appraisal, sale administration, and other compulsory collection costs. The calculator deliberately has no invented flat fee or percentage because these costs vary by authority, storage period, and case.
Verified senior claims
Include only claims confirmed to rank ahead of the seizure arrears after comparing the tax statutory date, lien registration date, and other applicable priority rules. A registered maximum secured amount is not necessarily the current loan balance. Obtain the actual principal, interest, and allowable cost balance.
Seizure arrears and subordinate claims
Enter the current tax and surcharge balance connected to the seizure, excluding enforcement costs already entered above. Add a subordinate claim only when its distribution position and amount have been confirmed. If priority is disputed, compare a conservative senior-claim scenario with an optimistic subordinate-claim scenario.
Planning distribution method
The calculation is a user-classified waterfall. It subtracts enforcement costs, verified senior claims, seizure arrears, and subordinate claims from the applied sale proceeds. At each step, recovery is limited to the smaller of the remaining proceeds and the entered claim. Any money left after every entered claim is shown as estimated owner surplus.
Worked example: all entered claims are covered
- Applied sale proceeds are KRW 17,000,000.
- KRW 1,000,000 of enforcement costs leaves KRW 16,000,000.
- KRW 4,000,000 of verified senior claims leaves KRW 12,000,000.
- KRW 8,000,000 of seizure arrears leaves KRW 4,000,000.
- KRW 3,000,000 of subordinate claims leaves KRW 1,000,000 as estimated owner surplus.
Worked example: arrears remain
With KRW 10,000,000 of proceeds, KRW 1,000,000 of enforcement costs, KRW 8,000,000 of senior claims, and KRW 5,000,000 of seizure arrears, only KRW 1,000,000 reaches the arrears. The recovery rate is 20%, and KRW 4,000,000 remains outstanding after the car is sold. The disposal of the vehicle does not itself discharge that remaining obligation.
Why the calculator does not infer legal priority
National Tax Collection Act Article 96 and Local Tax Collection Act Article 99 list categories that may receive a distribution. When proceeds are insufficient, however, the authority must determine rank and amount under the Civil Act and other laws. National tax priority can turn on Article 35 statutory dates, while local tax priority can turn on Local Framework Act Article 71. A mortgage registration date, a tax notice date, whether a tax was imposed on the vehicle itself, a delivery demand, and a timely distribution demand can all matter.
The vehicle register alone is therefore not enough. The calculator assumes that the user has already classified amounts as senior, seizure-related, or subordinate using the case record and professional advice. It never treats the order of data entry as an official distribution ruling.
Documents to review
- • Motor vehicle register entries for seizures and security interests.
- • Statutory dates and current balances for each tax claim.
- • Actual secured debt balance rather than only the registered maximum.
- • Delivery claims, creditor reports, and distribution demands.
- • Auction notice, appraisal, and draft distribution statement.
No-surplus review flag
National Tax Collection Act Article 57 addresses release where the estimated total property value leaves no amount after compulsory collection costs and claims that rank ahead of national tax. Local Tax Collection Act Article 104 provides a corresponding suspension rule for local-tax delinquency disposition. The calculator displays a review flag when the initial appraised value is no greater than entered enforcement costs plus verified senior claims.
This flag is not an automatic cancellation. Participating seizures, delivery claims, a revised appraisal, and statutory committee review can change the outcome. Use the flag to ask the case officer for the valuation, cost, and priority-claim basis and whether release or suspension may be considered.
Process checkpoints
- Seizure and registration: A court or tax authority requests a seizure entry under Motor Vehicle Management Act Article 14.
- Valuation and notice: The authority sets the reserve and notifies the debtor and recorded right holders under the relevant collection act.
- Bid or re-auction: A qualifying highest bid at or above the reserve may be selected. Failed rounds use the statutory reduction schedule.
- Sale decision and payment: National Article 84 and Local Article 92 generally set payment within 7 days of the sale decision, with an extension within 30 days when the authority finds it necessary.
- Transfer and distribution: Ownership follows full payment and registration. The authority prepares and implements the distribution according to confirmed rank.
National Tax Collection Act Article 98 and Local Tax Collection Act Article 101 require a draft distribution statement to be available before the distribution date and allow qualifying parties to request inspection or copies of supporting materials. Compare the calculator with that official draft rather than treating an early estimate as final.
Frequently asked questions
Does a public sale clear every tax debt?
No. Only the amount actually allocated to the arrears is recovered. If costs and senior claims consume most proceeds, the remaining arrears can survive the vehicle sale.
Can full payment stop the public auction?
Full payment or credit of the arrears connected to a national-tax seizure is a release ground under Article 57, and release creates a public-sale cancellation ground under Article 88. Timing, other seizures, and posting of payment still matter. Confirm release and cancellation directly with the officer immediately.
Should I enter the mortgage maximum as the senior claim?
Not automatically. The registered maximum secures a range of obligations and can exceed the current debt. Use the creditor report or current balance, then verify whether the claim actually ranks ahead of the tax.
Does five failed rounds guarantee a private sale?
No. The authority may set a new reserve and re-auction. Repeated failure can support a private-contract route when the statutory conditions are met, but the authority makes that decision.
Can this be used for a civil court vehicle auction?
It can illustrate a simple cash waterfall, but the legal model is for Korean national and local tax collection. Civil execution costs and court distribution procedures differ, so do not use this as a court distribution statement.
Official sources and maintenance date
The governing provisions and effective dates were checked through the Korean Ministry of Government Legislation National Law Information OPEN API on July 19, 2026. Future maintainers should recheck National Tax Collection Act Articles 57, 87, and 96; Local Tax Collection Act Articles 91, 99, and 104; National Framework Act Article 35; Local Framework Act Article 71; and Motor Vehicle Management Act Article 14 before changing formulas or guidance.
Estimate the remaining exposure before the sale
Gather the auction notice, vehicle register, current arrears statement, actual secured balances, and expected costs. Compare the current round with later failed-round scenarios to see how quickly recovery and owner surplus can fall.
Use the result as a planning worksheet only. The collecting authority distribution statement and a qualified Korean professional review control the legal outcome.
