Corporate Tax Revenue Projected to Surpass Income Tax for First in 15 Years on Semiconductor Boom

▲ Samsung Electronics and SK Hynix

Corporate tax revenue is projected to surpass income tax for the first time in 15 years next year.

Fueled by the semiconductor boom, corporate tax revenue will exceed 200 trillion won for the first time in history.

While concerns persist that tax revenues fluctuating with the semiconductor cycle could undermine fiscal management stability, the government plans to use a newly established Future Response Fund as a fiscal stabilization device.

According to the Ministry of Economy and Finance's national tax revenue budget released today (September 14), next year's corporate tax collection is expected to reach 216.7 trillion won.

This is 36.7 trillion won more than the projected income tax revenue (180 trillion won).

As the continuous semiconductor favorable trend is expected to significantly increase operating profits for semiconductor companies centered around Samsung Electronics and SK Hynix, corporate tax is also projected to surge.

This marks the first time since 2012 that corporate tax revenue has outpaced income tax.

At that time, income tax collection stood at 45.8 trillion won, narrowly ahead of corporate tax at 45.9 trillion won.

Corporate tax revenue grew from the 40 trillion won range between 2012 and 2015 to the 50 trillion won range in 2016 and 2017, and further to the 70 trillion won range in 2018 and 2019.

After shrinking back to 55.5 trillion won in 2020, it increased to 70.4 trillion won in 2021 and 103.6 trillion won in 2022.

Subsequently, amid a semiconductor market downturn, it dropped to 80.4 trillion won in 2023 and 62.5 trillion won in 2024.

This was a period when a massive tax revenue shortfall occurred as corporate tax receipts fell far short of expectations.

After recovering to 84.6 trillion won in 2025 and 101.3 trillion won based on this year's supplementary budget, corporate tax revenue is projected to more than double to 216.7 trillion won in next year's budget proposal.

This will be the first time in history that corporate tax revenue exceeds 200 trillion won.

While corporate tax revenue fluctuated from the 40 trillion won range to a peak in the 200 trillion won range depending on economic conditions, income tax revenue maintained a steady upward trend driven by inflation rates, an increasing number of workers, and rising asset prices.

Starting from the 40 trillion won range in 2012–2013, it grew steadily to enter the 100 trillion won range in 2021, recorded 130.5 trillion won in 2025, and was projected at 136.8 trillion won in this year's supplementary budget.

Next year, 180 trillion won is projected to be collected.

Value-added tax revenue dropped to third place in 2025 as corporate tax rebounded, and is projected to reach 91.4 trillion won next year.

Because South Korea has a "single-wing" economic structure heavily reliant on semiconductors for exports and growth, tax revenues tend to fluctuate sharply in tandem with semiconductor market conditions.

Concerns have continuously been raised that if unexpected economic downturns trigger massive tax revenue shortfalls, budget execution could be disrupted or policy capacity could be shaken.

Conversely, discussions are also becoming active on how to deploy tax revenues when they are collected far beyond expectations.

The government announced a plan to launch a new Future Response Fund to utilize it as a fiscal stabilization tool.

Lee Tae-seok, head of the Public Finance and Social Policy Research Department at the Korea Development Institute (KDI), stated at a seminar on the 11th, "While an exceptional increase in tax revenue is expected thanks to the semiconductor boom, sustainability remains uncertain as it is heavily dependent on the semiconductor industry's conditions." He added, "Since both the scale and uncertainty of this tax revenue increase exceed normal levels, it is necessary to seek a new fiscal system suited to changes in fiscal conditions."

He further noted, "Through the Future Response Fund, we can protect multi-year planned investments from the impact of tax revenue fluctuations and mitigate the risks of having to drastically cut expenditures or significantly increase government bond issuance during crisis situations."
