Korea NTS Commissioner Says Tax Reform on Registered Rental Apartments Could Release 68,000 Seoul Units

The Quick Take

• South Korea's National Tax Service Commissioner says reforming multi-owner rental tax exemptions could unlock 68,000 Seoul apartment units
• The proposal targets registered rental apartments where multi-property owners receive capital gains tax exemptions in exchange for tenancy obligations
• President Lee's government is reconsidering the registered rental housing system's tax benefits to address Seoul's chronic housing supply shortage

South Korea's National Tax Service Commissioner Lim Kwang-hyun has stated that reforming the tax treatment of registered rental apartments — specifically, reconsidering the capital gains tax exemption currently enjoyed by multi-property owners who register their units as rental housing — could effectively unlock 68,000 apartment units in Seoul's housing market. The current registered rental housing system allows multi-property owners to register their apartments as formal rental properties, receiving capital gains tax surcharge exemptions in exchange for providing tenant-favourable terms including capped rents and minimum tenancy periods. The Commissioner's analysis suggests that incentivising these owners to sell by reducing or eliminating the tax benefit could generate significant supply.

The proposal has direct implications for South Korea's real estate market dynamics, particularly in Seoul where housing affordability has been a persistent policy challenge. Multi-property owners who have locked up apartments in the registered rental system have been effectively reducing the tradeable supply in the resale market, contributing to price stickiness even during periods of government-led demand suppression. A policy change that encourages these owners to sell — by reducing the tax benefit of holding versus selling — would represent a supply-side intervention complementary to the demand-side measures that have dominated Korean housing policy in recent years.

The critical regulatory catalyst is whether President Lee's government formally adopts the NTS Commissioner's recommendation and proceeds with legislative amendment of the registered rental housing tax framework. Watch for National Assembly committee discussions on real estate tax reform, which will indicate the political feasibility of the 68,000-unit supply expansion scenario. Additionally, monitor Seoul apartment transaction volume and inventory level data monthly — any announcement of tax benefit removal for registered rental owners would likely trigger a wave of listings before the policy takes effect, creating a near-term supply overhang and potential price softening signal.
