amount, a non-resident is not entitled to basic deduction(except for himself), additional 
deduction(except for himself) and special deduction. A brief on the income deductions are 
addressed below. There are four exemptions and deductions related to global income. 
 
Residents with global income are entitled to annually deduct an amount equivalent to 1 
million Won multiplied by the number of persons in the taxpayer's family, as determined 
below.
¡© A resident taxpayer oneself

(fifty-five for females), a lineal descendent of the resident aged twenty or less(there is 
no age restriction for a handicapped person), a sibling aged under twenty or over sixty, 
and all other members of the household supported by the resident.
When a person who is qualified for Basic Deduction¡²oneself, his/her spouse, dependent
s¡³falls under any of the following situation, the amount calculated by multiplying the 
number of persons by the amount below, shall be deducted each year from the taxpayer's 
income under each case.

million Won respectively. 
Alternatively, a taxpayer may elect to choose an annual standard deduction of 600,000 
Won if he or she fails to claim deductions in question or accrues only global income 
without any wages or salaries earned.
   Scope of Persons Eligible for Personal Exemptions and Determination of Eligibility  
Persons eligible for spousal exemption, dependent exemption, or exemption for handicapped 
or aged persons must be (i) a spouse and/or unmarried lineal descendant and (ii) family 
members who are listed on the registration card of the resident actually living at the 
domicile or residence. A person who has temporarily left the taxpayer's domicile or

existing conditions at the close of the tax period in question.

contribution paid for pension insurance in the name of the taxpayer him/herself is 
deducted.

Pension Law

Service Pension Law etc.
The tax amount on global income is the aggregate of amounts calculated by applying each 
tax rate successively to the income in the relevant tax bracket:
The tax amount of retirement income is calculated by dividing the taxable income by the 
number of years of service, applying the tax rates, and again multiplying the amount by 
the number of years of service.
Tax rates on timber income are the same as those applied to global income.
Where a resident has paid or is to pay foreign income tax abroad, the tax amount payable 
is deducted from the income tax within the limit of an amount equivalent to an amount 
calculated by multiplying the income tax amount by the ratio of income from foreign 
sources to the total taxable income. If any foreign income tax amount paid or to be paid 
to a foreign government, exceeds the deduction limit, the excess amount may be carried 
forward to the taxable period to be terminated within five year from the taxable period 
following the current taxable period, and deducted within the deduction limit of that 
taxable period. An application for deduction shall be filed with the competent District Tax 
Office or the tax withholding agent not later than the end of the final tax return period or 
the end of the year-end adjustment period.
 
Where a resident's dividend income from domestic corporations is counted in the global 
income, an amount calculated as follows is deducted from the global income tax amount.
¡©  19/100 of the corporate income tax attributable to the dividend in question will be 
added to the amount of dividend income actually received by a shareholder.
¡©  This figure will then be used to calculate the individual income tax of the shareholder.
¡©  Thereafter the 19/100 portion will be credited against the calculated individual income 
tax amount or will be refunded to the shareholder.
The following amounts shall be credited against global income tax on wage and salary 
income. Where the amount of credit exceeds 500,000 Won, the credit is limited to 
500,000 Won.
   
 In the case of daily worker, the amount of credit is limited to total tax multified by 
55%.
If a resident has lost 30% or more of the total value of his business assets due to a 
disaster, the tax amount equivalent to the ratio of the value of lost assets to the value of 
total assets is deducted from the income tax amount.
If a person subject to Simple Book Keeping calculates his income amount on the basis of 
the entries in the book exhibited and entered, and submits the document in making a final 
return on tax base pursuant to the provisions of Presidential Decree, the outcome obtained 
by multiplying by 10/100 the amount calculated by multiplying the calculated global 
income tax amount or the calculated forestry income tax amount by the ratio of the sum 
of real estate rental income and business income calculated pursuant to the entries in the 
book from the global income, or the ratio of the forestry income calculated pursuant to 
the entries in the book to forestry income shall be the amount deducted. If the amount 
subject to deduction exceeds one million won, only one million won shall be deducted.
Under the 1994 tax reform, the individual income tax assessment system was converted 
into a self-assessment system under which each taxpayer is required to file a return and 
pay the proper amount of tax by the due date as prescribed by the individual income tax 
law.
A resident with global income is subject to pay, as interim prepayment, an amount 
equivalent to half of the global income tax amount paid or payable in the preceding year,

payable and the amount of penalty taxed.
