12. Penalty Tax
A penalty tax for a failure to meet the prescribed obligations is added to the tax due.
  a. Penalty Tax on Failures in Bookkeeping or Filing Returns:
Where a corporation has failed to file returns or where the obligation of bookkeeping has
not been met, the penalty tax of 20% of the calculated tax amount determined by the
government, or an amount equivalent to 0.07% of the amount of gross receipts,
whichever is greater, is imposed. However, when the under-declared amount exceeds 5
billion won, 30% of the tax amount due or an amount equivalent to 0.1% of the amount of 
gross receipts, whichever is greater, is to be paid. Note that the penalty tax for the failure
in bookkeeping does not apply to non-profit corporations.
  b. Penalty Tax on Understatement of Income:
When a taxpayer fails to accurately report his tax amount due, he or she is subject to the
penalties described below.
(i)  If the under-declared amount is more than one-third of the tax base and an
"unjustifiably under-reported tax amount" as prescribed by the Presidential Decree
exceeds 5 billion won, 30% of the tax amount due on the under-declared amount is to be
the penalty payment. However, if the tax amount due represents less than 0.1% of the
gross receipts or is zero, 0.1% of the gross receipts will be considered as the amount
due. 
(ii)  In other cases, 10% of the tax amount due on the under-declared amount (20% of
"unjustifiably under-reported tax amount") will be considered the penalty.  If the
calculated tax amount is zero, then this rule does not apply.
  c. Penalty Tax on Non-payment or Insufficient Payment:
Where the corporation tax has not been paid in full or in part, the penalty tax is an
amount equivalent to 0.03% per day of the amount of corporation tax unpaid or left to be
paid.
  d. Penalty Tax for Failure to Withhold Tax
(1) Where tax withholders have failed to withhold tax at the source or have failed to pay
the withheld tax to the government within the payment period, the penalty tax applied
is the larger of 
i)   An amount that multiplies 0.03% by the number of unpaid days (limited to 10% of unpaid tax)
ii)  An amount equivalent to 5% of unpaid tax.

tax to the corporation income tax.
  f.  Penalty Tax on Failure to Receive Verifying Documents
Where a corporation (except those exempted under the Presidential Decree) is provided
with goods or services in connection with the business and does not collect verifying
documents required, the corporation is subject to penalty tax equivalent to 20% of the
uncollected amount surcharged on corporate income tax, except as otherwise provided
in the article.  Even when the taxable amount is zero, the penalty tax is still to be paid.
  g.  Penalty Tax on Failure to File a Stock Transfer Status Sheet
If a corporation fails to file a stock transfer status sheet by the due date, or if it is filed by
the corporation with incorrect information or omissions of required information, a penalty

  h.  Penalty Tax on Failure in Reporting

transactions submitted by the company are found to be unclear, an amount equivalent to
2% of the amount of the transactions in the reports not submitted or unclear is assessed
as penalty tax.
