Seoul: Housing markets often tempt governments into believing that taxes can solve issues typically addressed by expanding supply. When prices climb, fiscal tools offer the appeal of speed and political visibility. Yet, housing shortages are rarely solved through the tax code. They are addressed by expanding supply and allowing markets to function with fewer distortions.
According to Yonhap News Agency, the administration of Lee Jae Myung is signaling a possible tightening of real estate taxes. The president recently noted that Korea's holding taxes are relatively low, while Presidential policy chief Kim Yong-beom suggested stronger taxation might be necessary to prevent liquidity from the semiconductor boom from flowing into property markets. With July's tax overhaul approaching, the prospect of higher holding and capital gains taxes is triggering renewed disputes.
Concerns about overheating are understandable. Housing prices in parts of southern Gyeonggi Province, particularly around the semiconductor belt, have accelerated as large bonuses and rising asset values boost purchasing power. Apartment prices in Dongtan, for instance, rose 2.22 percent in the third week of June alone. However, the government's diagnosis becomes less convincing as money usually chases scarcity.
Housing permits, construction starts, and completions have all been declining. Supply plans have been announced repeatedly, yet visible progress remains limited. As future inventories shrink, liquidity becomes an amplifier rather than the source of the problem. Apartment move-ins this year are projected to be almost 40 percent below 2022 levels, with a decline approaching 46 percent in the Seoul metropolitan area.
Both sale prices and "jeonse" costs are rising, intensifying competition for scarce homes and adding to anxiety among potential buyers and renters. History offers little encouragement for punitive taxation, as higher capital gains taxes often discourage sales rather than speculation. Higher holding taxes frequently shift into rents and jeonse deposits, shifting the burden rather than eliminating it.
The structure of Korea's property taxes deserves a broader perspective. Comparisons focused solely on effective holding tax rates can be misleading. Transaction taxes and capital gains taxes are already heavy by international standards, positioning Korea among the more heavily taxed property markets within the Organization for Economic Cooperation and Development. Raising all three property taxes simultaneously would further reduce market liquidity.
Tax systems work best when different levies complement rather than reinforce one another. Closing every avenue at once would freeze transactions and leave prices detached from market reality. As the Bank of Korea is expected to tighten monetary policy, imposing heavier taxes would pressure households from both directions.
Such burdens may be manageable for investors with abundant cash, but they weigh heavily on retirees and ordinary homeowners whose assets are valuable on paper but whose incomes are fixed. While tax policy need not remain frozen forever, gradual adjustments to holding taxes could be justified if accompanied by reductions in transaction taxes. Markets function best when entry and exit are both possible.
The more pressing challenge remains supply. Faster redevelopment, more housing starts, and stronger incentives for private builders would do more to steady expectations than another round of tax warnings. Lee has repeatedly stressed the importance of expanding supply, emphasizing that execution is crucial. Governments can change tax rules quickly, but housing operates on a slower timetable, and lasting stability depends on ensuring enough homes are built to meet demand. Tax policy has a role but cannot substitute for supply.
