Korean Traditional Liquor Excise Relief and Release Tax Calculator

Check the excise band before the next traditional-liquor release

This Korea-specific calculator applies the 2026 Korean liquor tax rules to supported traditional liquor released from a domestic manufacturing location.
It helps a farm producer or small distillery budget excise for its next delivery and prepare a review ledger for a tax adviser.
A product’s marketing name does not establish statutory traditional-liquor status, and not every release qualifies for the same reduced rate.

Previous-year taxable volume determines ordinary eligibility, while the order of current-year releases determines how much of each band remains.
The calculator splits a release crossing a boundary into separate quantities and taxable bases.
Filed transactions remain in the volume sequence but are excluded from pending tax.
Confirm the license, legal product classification and traditional-liquor evidence before using the result.

Supported categories and exclusions

Takju, beer, other liquor categories, ethanol, imports and contract manufacture are outside this version.
Takju’s specific-volume tax and its rate truncation below KRW 100, and beer’s special taxable-volume ratios, are not reproduced by this ad valorem calculation.
Education tax, VAT, exemptions, returned-goods adjustments, raw-material credits and penalties are separate.
Changing the selected category clears the release volumes, so export a previous ledger first.

Previous-year thresholds, new licenses and first-excess grace

A Korean brewing year runs from January 1 through December 31.
Enforcement Decree Article 7(2) uses previous-year taxable releases: no more than 1,000 kL for fermented liquor and 500 kL for distilled liquor.
The exact limit is included; a volume even 0.0001 kL above it requires a separate examination of exceptions.
Verify the complete statutory aggregation scope for the product and manufacturing location instead of dividing a business’s releases arbitrarily.

If the previous year exceeds the limit and the exception history or starting year is unresolved, the calculator places tax on hold.
If the grace period has expired but a verified previous-year volume is again below the limit, ordinary eligibility can still apply independently.
A license year, product category and manufacturer’s aggregation scope must be supported by evidence.

Reduction percentages and effective rates

A 50% reduction removes half of the base rate.
For fermented liquor, a 30% base rate therefore becomes 15%; a 30% reduction leaves 70% of that base rate, or 21%.
The corresponding distilled-liquor rates are 36% and 50.4%.
The annual sequence is based on taxable releases, not a fresh allowance for each invoice.

A manufacturer that does not satisfy relief eligibility uses the base rate from its first release.
An eligible manufacturer also uses the base rate for quantities exceeding the final relief band.
A single release crossing a boundary must be allocated between bands rather than taxed entirely at one effective rate.

Use a verified excise tax base and allocate by quantity

Enter the total verified excise tax base for the release, rather than retail receipts or the amount credited to a bank account.
Act Article 7 and Decree Articles 5 and 5-2 govern taxable prices, including relevant transaction methods, packaging, small-producer price ratios for yakju or cheongju, and standard-sales ratios.
The calculator expects those adjustments to have been applied already and does not deduct them again.
Leave tax-base confirmation unverified when the calculation cannot be supported.

Use separate rows for quantities with different taxable unit prices, even on the same day.
Keep their actual release order.
Quantities use integer 100 mL units so decimal arithmetic does not accidentally move a release across a 100 kL or 200 kL boundary.
The calculation retains proportional fractional bases before rounding the final release tax to whole KRW for reference.
This display convention is not the official return’s statutory truncation rule.

Enter the ledger in five steps

1. Verify the legal category, traditional-liquor evidence, domestic own manufacture and annual aggregation scope.
   Keep different products or locations in the correct legal scope.
   
2. Enter the manufacturing license year and 2025 taxable release volume.
   If applicable, enter an authority-verified first-excess grace start year.
   
3. Enter 2026 taxable volume released before the rows in this ledger.
   It occupies earlier bands, but its historical tax is not reconstructed.
   
4. Add releases in chronological order with quantity and the verified total excise tax base.
   Mark filed rows and avoid duplicating their quantities in the opening volume.
   
5. Calculate, check the eligibility reason and pending tax, then export the review ledger.
   Resolve any outstanding evidence and calculate again.
   

Changing an input clears the previous result and export to prevent an old tax figure being mistaken for the revised calculation.
The form rejects zero or missing quantities and taxable bases, invalid dates, dates in reverse order, and unsupported precision.
Up to 40 rows can be entered, with dates restricted to the 2026 brewing year.

Worked fermented example: 190 kL plus a 20 kL release

Applying 15% to the entire new release would overstate the reduction.
The example cannot establish the total annual relief because taxable prices for the earlier 190 kL were not supplied.
Entered-ledger cumulative relief covers only rows actually entered.
To include the earlier releases in that amount, enter their actual tax bases as filed rows and remove the corresponding quantity from the opening balance.

Distilled examples and the final relief boundary

If an earlier row is filed and a later row is pending, both rows consume the annual bands, while only the later row enters pending excise.
Filed-row tax is shown separately for comparison, rather than treated as a credit or refund.
Where an earlier return used a different verified base or filing truncation, reconcile it with the original return and the adviser’s calculation.

Interpret the totals and the next-year scenario

Pending release tax is the sum for rows not marked filed; it is not a final balance payable.
Filed tax and cumulative relief within the entered ledger are separate measures.
Remaining relief volume is not displayed when eligibility is pending or relief does not apply.
The 30% band balance includes its still-available volume even before the 50% band has been exhausted.

When comparing delivery plans, enter confirmed releases first and append only the proposed releases under examination.
Do not omit earlier transactions to restart an allowance or claim relief again on a filed release.
The manufacturer’s statutory product and location aggregation scope is an evidence requirement, rather than a conclusion established by this calculator.

Units, rounding and filing cautions

1 kL = 1,000 L, and 0.0001 kL = 100 mL.
The form rejects finer input precision instead of silently truncating each row.
Enforcement Rule Article 3(2) addresses quantities aggregated by liquor type, specification or capacity before discarding fractions below 100 mL in the return.
That separate filing process is not equivalent to arbitrarily rounding an individual release.

Allocated tax bases retain fractional KRW; the final estimate is rounded to whole KRW for each release.
Displayed rounded band figures can therefore differ from a release total by KRW 1.
Reconcile actual filing aggregation and truncation with the official return calculation.
Also check small-producer price ratios, standard-sales ratios, packaging and distance-selling price treatment in the underlying tax-base workpaper.

Do not enter zero for a release whose price is unknown, or mark evidence verified simply to obtain a number.
Unresolved inputs identify work that remains before filing.
Exports contain references and transaction details; internal document numbers can be used instead of customer names, and the file should be stored appropriately.
