Cash Incentives (Performance Bonuses)

A cash-based incentive paid by companies to workers in return for achieving performance targets, and a central subject of disputes over whether it counts as ordinary wage

Cash Incentives (Performance Bonuses)

Overview

Cash incentives (Cash Incentive, Cash Bonus) are monetary compensation paid by a company to workers in return for the achievement of work performance or business performance targets by individuals, teams, or the organization. Unlike non-cash compensation such as stock options, RSUs, and stock-based compensation, they can be converted into cash immediately and are not swayed by market variables at the time of payment, making them the most common and direct means of incentive. At the same time, they are also a core point of contention over which legal disputes between labor and management are repeatedly waged, namely whether they are included in the calculation of ordinary wage and average wage.

Definition and Nature

A performance bonus is a representative form of variable pay, as opposed to fixed pay such as base pay, job-based pay, and seniority-based pay. In the wage system, fixed pay is paid regularly and uniformly in accordance with the employment contract and the rules of employment, whereas a performance bonus varies in amount or even in whether it is paid at all, depending on performance, target achievement rate, and evaluation grade. Accordingly, performance bonuses simultaneously perform a compensation function and a motivation function, and also carry the human resource strategic purposes of retaining excellent talent (retention) and putting pressure on low performers.

Classification by Type

Individual performance bonus: Differentially paid according to an individual worker's KPI/MBO achievement rate. Sales incentives are the typical example.
Team/department performance bonus: Distributed based on the degree of achievement of organizational-unit targets. It is advantageous for inducing collaboration, but free-rider problems can arise.
Company-wide performance bonus: Linked to the performance of the company as a whole, such as operating profit and revenue. Profit Sharing and Gain Sharing fall under this category.
Excess profit sharing (PS, OPI): Paid with a certain percentage of profits exceeding the target as the funding source. Samsung Electronics' OPI and SK Hynix's PS are representative examples, and the amount fluctuates very widely depending on the semiconductor industry cycle.
Long-term incentive (LTI): Paid based on multi-year performance of three years or more, and is often combined with deferred payment and clawback provisions.

Calculation Method and Payment Form

Calculation is linked to performance management systems such as Management by Objectives (MBO), Key Performance Indicators (KPI), and OKR. In general, a cap is set as a certain multiple of base pay (e.g., 0–100% of base pay) or as a certain percentage of annual salary, and the amount is determined by multiplying by the payment rate for each evaluation grade. Payment timing varies, including once a year (at year-end or early the following year), semiannually, quarterly, or every other month, and recently a deferred payment method that splits part of the performance bonus and pays it out over two to three years has spread, centering on the financial sector.

Legal Issues

The most acute issue is whether it constitutes ordinary wage. Because ordinary wage serves as the calculation basis for overtime, night, and holiday work allowances, annual leave allowances, and advance notice of dismissal allowances, if a performance bonus is included in ordinary wage, the company's labor cost burden increases significantly. A 2013 Supreme Court en banc decision presented regularity, uniformity, and fixedness as the requirements for ordinary wage, and afterward the ordinary wage nature of employment-conditioned bonuses and performance bonuses was decided inconsistently in lower courts, continuing the debate. In December 2024, the Supreme Court en banc effectively abolished the fixedness requirement and ruled that conditional wages can also be ordinary wage, greatly increasing the possibility that the scope of performance bonuses and regular bonuses included in ordinary wage will expand. In addition, the opacity of performance bonus payment criteria, the absence of procedures for objecting to evaluation results, and whether changes to the rules of employment are disadvantageous are causes of labor-management disputes.

Taxes and Social Insurance

Performance bonuses are classified as earned income and are subject to earned income tax and local income tax, and are included in the total remuneration for the National Pension, National Health Insurance, Employment Insurance, and Industrial Accident Compensation Insurance. Because they are added to total wages at year-end tax settlement, the tax burden surges in a year when a large performance bonus is received, and after the reform of the health insurance premium imposition system, issues of change in dependent eligibility also arise in connection with non-wage income and the settlement process. Executive performance bonuses are subject to remuneration disclosure under the Capital Markets Act, and listed companies are increasingly disclosing payment criteria and clawback details due to the Stewardship Code and ESG disclosure requirements.

Accounting and Management Aspects

Performance bonuses are treated as labor costs and selling, general and administrative expenses, and in principle are recognized as an expense in the fiscal year in which the payment obligation arises. However, in cases where payment requirements are not met, they may be recorded as a provision for liabilities. From management's standpoint, performance bonuses are a flexible compensation tool that drives performance without increasing fixed costs, but they have a double-edged nature in that they can plunge when business performance deteriorates, causing a decline in organizational morale and the departure of key personnel.

Latest Trends

The environment surrounding cash performance bonuses in 2024–2025 is changing in three major directions. First, with the recovery of the semiconductor industry cycle, the scale of excess profit sharing payments at major companies such as Samsung Electronics and SK Hynix is expanding again, while the gap between business divisions is widening, reigniting controversy over fairness. Second, after the Supreme Court en banc ruling on ordinary wage in December 2024, the possibility that conditional performance bonuses may be included in ordinary wage has opened, prompting companies to begin reforming their wage systems to manage the risks of retroactive wage burdens and allowance recalculation. Third, centering on the financial sector, deferred payment and clawback systems linked to the implementation of the accountability structure are taking hold, and voices demanding transparency in performance bonus calculation criteria and evaluation processes are growing at general companies as well. Along with this, as management uncertainty persists due to high interest rates and high exchange rates, the trend toward strengthening performance-based pay is becoming clear, including reducing compensation for low performers, transitioning to job-based pay, and OKR-based compensation.
