  • 20% + KRW 20 million (from KRW 200 million to KRW 20 billion)
  • 22% + KRW 3,980 million (between KRW 20 billion and KRW 300 billion)

Tax Rate For Foreign Companies
Resident corporations are taxed on their worldwide income. Non-resident corporations with a permanent establishment in Korea are taxed only on their Korean-source income. Non-resident corporations without a permanent establishment in Korea are generally taxed through a withholding tax on each separate item of Korean-source income.

A resident company subject to tax in Korea and overseas is entitled to a foreign tax credit for foreign tax paid in respect of income earned overseas (limited to the amount of tax payable in Korea). The excess foreign tax credit can be carried forward for up to 10 years from the fiscal year starting 1 January 2021.

Capital Gains Taxation
For resident companies, capital gains are treated as ordinary business income and taxed at the normal corporate tax rate. However, capital gains from the sale of non-business purpose real estate are subject to additional capital gains tax, at the rate of 10% (40% in the case of non-registered land or houses).
For non-resident companies, Korean-source capital gains are taxed at either 11% of sales or 22% of gains (whichever is less). In general, no special taxes are levied on gains from mergers.
Main Allowable Deductions and Tax Credits
As a general rule, expenses incurred in the ordinary course of business are deductible, with those above KRW 30,000 needing to be supported by qualifying evidence.

A doubtful accounts reserve is allowed as a deduction for tax purposes at the greater of 1% on the tax book value of the receivables at a year-end or actual bad debt ratio (does not apply to financial institutions). Entertainment expenses of more than KRW 30,000 on an event basis supported by corporate credit card vouchers, cash receipts, or tax invoices can be deductible (up to certain limits). With some exceptions, interest paid in the ordinary course of business is deductible as long as the related loan is used for business purposes. Insurance premiums paid to an insurance company are deductible.

Start-up expenses, such as incorporation expenses, founders’ salary, and registration fees and taxes, are deductible if the expenses are recorded per the articles of incorporation and are actually paid. Goodwill can be amortised over a period of five years using the straight-line method.

Certain charitable  can be considered either "Bub-jung" (deductible at up to 50% of the total taxable income for the concerned fiscal year after deduction of net operating loss) or "Ji-jung" (which can be deducted up to 10% of the total taxable income for the fiscal year after the deduction of deductible Bub-jung donations and net operating loss). The amount in excess of such limits can be carried over for ten years.

Net operating losses can be carried forward 10 years up to 60% of a fiscal year's taxable income, or for 15 years when incurred in fiscal years starting on or after January 1, 2020. The carryback of losses is not permitted for big companies; however, SMEs can carry back their losses to the previous accounting year (up to the preceding two years for the net operating losses of tax year including 31 December 2021).

For tax years ending before 31 December 2020, a special deduction from 5% to 30% (depending on corporate location, size, business types, etc., capped at KRW 100 million) applies to SMEs operating in a qualified business (applicable to taxable income arising in the tax years that end before 31 December 2022). Furthermore, several tax credits are available for qualified investments.

A securities transaction tax is imposed on the transferor of shares at 0.35% (0.43% from 1 January 2021 through 31 December 2022) of the share transfer price. The rate is reduced to 0.1% (0.23% from 1 January 2021 through 31 December 2022), depending on the stock market, where listed shares are transferred.

Companies acquiring real estate, motor vehicles, heavy equipment, and certain other items must pay acquisition tax, generally at 4.6% (including the local surtax).
