WH Baik, Jeremy Everett
The new government's tax policy has already proven to be substantially different from the prior administration, with proposed tax law amendments that feature increases in corporate income tax rates, individual income tax rates, new limitations on interest deductibility, new limitations on the use of net operating loss carry-forwards, the elimination of various tax incentives, and a substantial broadening of the foreign bank account reporting requirements.
The National Assembly will review the proposed amendments and is expected to pass them before December 31 2017, though some changes are expected. The bulk of the amendments should be effective from January 1 2018. The following highlights are worth noting.
For well over a decade, Korea has been consistently decreasing its corporate income tax rates to be more competitive with other OECD countries. In a dramatic return to the past, the Moon Administration has proposed adding a new 27.5% corporate income tax bracket for income in excess of KRW 200 billion ($177 million) to help fund increased spending on social welfare programmes. Details are as shown in Table 1.
|CITL||Corporate Income Tax Law|
|IITL||Individual Income Tax Law|
|ITCL||International Tax Coordination Law|
|NTBL||National Tax Basic Law|
|STTCL||Special Tax Treatment Control Law|
|VATL||Value Added Tax Law|
|Current corporate income tax rates (including local income tax)||(Proposed change) Addition of 27.5% rate for taxable income over KRW 200 billion (including local income tax)|
(Application) Tax years commencing on or after January 1 2018.
Over the past decade, Korea increased the NOL carry-over period from five years to 10 years in an effort to provide support for companies suffering from increased losses during the global financial crisis. The previous (Park) administration took initial steps to scale back the benefit of the ten year NOL carry-forward period by establishing an 80% annual cap on taxable income that can be offset by an NOL carry-forward. The Moon administration is seeking to further eliminate the benefit of NOL carry-forwards by dramatically decreasing the cap, first to 60%, from January 1 2018, and then to 50%, beginning in 2019, as described in Table 2.
|NOLs can be carried forward up to 10 years and used to offset up to 80% of taxable income in each carry-forward year.----The 80% cap does not apply to small and medium size enterprises (STTCL-PD §5①), or companies under rehabilitation and bankruptcy proceedings.||
(Proposed Change) Gradual reduction from 80% cap to 50% by 2019
• Annual deductible limit for NOL carry-forwards: 60% of taxable income (for tax years beginning January 1 2018) and 50% (for tax years beginning January 1 2019)
The existing excess retained earnings tax regime was enacted in 2015 to stimulate consumption by incentivising investments in new assets, salary increases and dividend distributions. It is scheduled to expire on December 31 2017. As the Moon administration believes the previous tax regime was ineffective in meeting its stated objectives, a new regime is proposed that would tax excess retained earnings at a 20% rate (rather than the current 10% rate) while eliminating the ability to reduce the amount of earnings subject to the tax by paying dividends or purchasing land. Like the previous regime, the proposed amendment is temporary and provides a 2020 expiration date, as described in Table 3.
Excessive retained earnings tax: Introduced in 2015 to encourage companies to stimulate consumption through investments in assets, salary increases, and dividend distributions.
• corporations with net assets exceeding KRW 50 billion
• members of conglomerate groups subject to cross-shareholding restrictions
• Applicable tax rate: 10%.
• Corporations may choose Method A or Method B below. (This choice cannot be changed for the following three years.)
Method A: [Current year income × 80% - (qualifying investments + (150% × qualifying salary increases) + mutual cooperation contributions + (50% × dividends paid))] × 10%
Method B: [Current year income × 30% - ((150% × qualifying salary increases) + mutual cooperation contributions + (50% × dividends paid))] × 10%
(Salary multiplier increases to 200% for salary increases for young full-time employees.)
• Please note that if qualified expenditures (i.e. investments, salary increases, and dividend distributions) in a relevant year exceed current year income multiplied by the usage ratio (80% for Method A; 30% for Method B), the excess can be carried over to other tax years to reduce earnings that would otherwise be subject to the tax.
• Eligible mutual cooperation contributions:
i) Contributions to mutual cooperation fund
ii) Contributions to small and medium size corporation’s employee welfare fund
iii) Contributions to joint employee welfare fund
• Salary increases for employees earning more than KRW 120 million are excluded.
Expires December 31 2017.
• Applicable tax rate: 20%
• Corporations may elect either Method A or Method B below:
A: [Current year income × 60-80% - (qualifying investments + (150% × qualifying salary increases) + (300% × mutual cooperation contributions))] × 20%
B: [Current year income × 10-20% - ((150% × qualifying salary increases) + (300% × mutual cooperation contributions))] × 20%
• Dividend distributions and investments in land are no longer qualifying expenditures.
• Usage ratio to be decided by Presidential Decree (Method A: 60~80%; Method B: 10~20%).
• Current year income exceeding KRW 200 billion excluded from taxation
(Salary multiplier increases to 250% for salary increases for young full-time employees and to 200% for salaries paid for newly created jobs)
• Salary increases for employees earning more than KRW 70 million excluded.
• (Interim carry-forward) Any excess expenditures carried over based on the previous regime can be used to offset current year earnings.
(Application) Tax years commencing on or after January 1 2018. The provision is to expire on December 31 2020 (i.e., at end of tax year that includes December 31 2020).
Historically, Korea has capped interest expense deductions for related-party loans or loans from unrelated parties guaranteed by offshore related parties at three times equity (or six times in the case of qualifying financial institutions). This debt/equity threshold was lowered under the Park administration from 3:1 to 2:1, and the Moon administration seeks to further limit interest expense deductibility by introducing an entirely new cap set at 30% of adjusted taxable income, as described in Table 4.
|Thin capitalisation rule: If borrowing from a foreign controlling shareholder exceeds twice the equity invested by the foreign controlling shareholder (six times in case financial institutions), interest attributable to the excess borrowing is not deductible.||
• Interest expense deductions will be denied to the extent of the greater of: (1) the amount denied under the current thin capitalisation rules, and (2) net interest expense in excess of 30% of adjusted taxable income.
For this purpose, adjusted taxable income and net interest expense are defined as follows:
• Adjusted taxable income: taxable income plus depreciation on fixed assets and net interest expense.
• Net interest expense: Total interest paid to foreign related parties less total interest received from related parties (as defined in the International Tax Coordination Law).
(The new limitations will not apply to financial and insurance businesses.)
(Application) Tax years commencing on or after January 1 2019.
True to campaign pledges, President Moon's administration has proposed a dramatic increase in individual income tax rates, featuring an increase of the top rate to 46.2% for income in excess of KRW 500 million and a 44% tax rate for income in excess of KRW 300 million, as outlined in Table 5.
|Tax brackets and rates (including local tax)||(Proposed change) lower ceiling on current top tax bracket and create new top marginal rate|
(Application) Applies to tax years beginning on or after January 1 2018
Under the Park administration, foreign accounting reporting requirements were put in place for taxpayers with an aggregate account balance exceeding KRW 1 billion at the end of any given month. The Moon administration has expanded the scope of this reporting regime to cover all taxpayers having an aggregate account balance exceeding KRW 500 million at the end of any given month.
On June 7 2017, Korea signed the MCAA, the latest step in the BEPS project. Approximately 45 of Korea's 91 tax treaties will be revised in the wake of Korea signing the MCAA. The revisions will become effective three months after both Korea and each contracting state submit their ratification instruments to the OECD (on the beginning of the month following the three-month ratification period). The MCAA will give rise to the following changes:
As the digital economy continues to grow, Korea has joined many countries around the world in seeking to adopt new tax laws or change the way existing laws and bilateral tax treaties are interpreted to aggressively tax IT companies.
As an initial step, the NTS has been conducting tax raids in which dozens of auditors show up at the taxpayer's place of business without advance notice with the intent to temporarily seize documents, files, and personal computers for further investigation. These tax raids have been conducted with the goal of deeming global IT companies as having a taxable nexus (a permanent establishment) in Korea. Once a permanent establishment (PE) is deemed to exist, the NTS attributes revenue recognised outside of Korea to such PE and imposes corporate income tax, VAT and penalties on such revenue.
In determining whether a PE should be deemed to exist, the NTS tends to focus on the existence of a server or core equipment in Korea as well as the involvement of Korean personnel in core functions that go beyond ancillary support services.
Both the National Assembly and President Moon's new administration have announced their intention to pursue new legislation and new policy initiatives aimed at both combatting aggressive tax planning and further taxing the digital economy. They are particularly focused on taxing deemed PEs of multinational IT companies with global revenue from cloud-computing or internet-based services and comparatively small tax revenue reported in Korea. It is also expected that the Korean government will continue to consider methods to impose VAT on the provision of IT services from outside Korea.
The new customs duty law enforcement regulations, which became effective on July 1 2017, provide that certain taxpayer-initiated transfer pricing adjustments (both upward and downward) may give rise to additional customs duties or refunds. This will be accomplished by allowing importers to file provisional import customs declarations. Taxpayer-initiated adjustments under the transactional net margin method may be potentially eligible for the provisional import entry system. In order to qualify for this program, however, importers should have a valid advance pricing agreement (APA) or ACVA (the customs equivalent of a unilateral APA) and submit the following transfer pricing-related documents for further review:
South Korea's President, Moon Jae-in, was sworn into power in May 2017 and he is determined to address the social issues in his country. These issues include an aging population that will require healthcare and social services to look after it. There is also the issue of rising inequality in South Korea. This was highlighted in the abuse of power scandal that led to the impeachment of Moon's predecessor, Park Geun-hye. In August 2017, Samsung heir Lee Jae-yong was sentenced to five years in prison.
Lee's conviction is not the only sign of big business behaving in an unethical manner. In the past year, Daewoo Shipbuilding & Marine Engineering (DSME), one of South Korea's major corporations, was at the centre of an accounting scandal. This scandal was in relation to the overstatement of profits for certain years. Ko Jae-ho, the former CEO of DSME, was sentenced to 10 years imprisonment for his involvement in the scandal.
Moon came into power on a wave of popular support for change in South Korea. His administration has proposed an increase in the minimum wage for South Korean workers over a five-year period. It hopes that this will help tackle the country's income inequality. This policy, along with others that address other social issues and welfare costs, will lead to greater government spending.
Moon's administration will have to increase the country's tax base to get the necessary revenue. In August 2017, the South Korean government proposed to increase the tax rates. Corporate tax will rise from 22% to 25% for companies with revenues in excess of KRW200 billion ($177 million) per year. Income tax will rise from 38% to 40% for individuals who earn more than KRW300 million. There will also be an income tax rise from 40% to 42 % for those earning more than KRW500 million.
Moon hopes that these proposed tax increases will reduce the dominance of South Korean conglomerates and help with his administration's welfare agenda.
