🏛️ ‘Live In It, or Pay More’ — Korea Kicks Off a Residence-Focused Property Tax Overhaul

Korea’s government has launched a “residence-focused” overhaul of property taxes that touches acquisition, holding and capital-gains taxes all at once. The core idea is to draw a clear line between people who actually live in the home they own and those who do not. For capital-gains tax, the direction is to shrink the deduction tied to mere holding while expanding the live-in benefit; for the holding tax, the leading option is raising the “fair market value ratio,” which the government can adjust without parliamentary approval. A concrete blueprint is expected to take shape late this month.

TL;DR

The government is pursuing a “residence-focused” overhaul that views acquisition, holding and capital-gains taxes together, judged by the total tax burden across buying, holding and selling a home.
For the capital-gains long-term holding deduction (currently up to 40% for holding + up to 40% for residence = 80% combined), the likely move is to cut or scrap the holding portion while enlarging the residence portion.
For the holding tax, the key is raising the fair market value ratio (now 60%). Because it sits in an enforcement decree, the government can lift it without parliamentary approval — and even without touching nominal rates, a larger tax base effectively means a tax hike.

What happened?

The government has made clear it intends to rebuild property taxation around actual residence. President Lee Jae-myung signaled the stance that “if you’re not living in it, you should bear a holding burden on par with advanced economies,” and the Ministry of Economy and Finance is weighing a comprehensive overhaul spanning the entire ownership cycle — acquisition, holding and disposal. The crux is to bundle acquisition, holding and capital-gains taxes — previously handled separately — into a single “total tax burden” framework and redesign the system around it.

One change has already begun. With the temporary suspension of the heavier capital-gains tax on multiple-home owners ending on May 9, the surcharge rate has applied again since May 10 to multiple-home owners in regulated zones. This overhaul extends that line of policy to the tax system as a whole.

How would capital-gains tax change?

The first item on the table is the long-term holding deduction within the capital-gains tax. Today, a single-home household can deduct up to 40% of the gain based on years held and up to 40% based on years of residence — up to 80% combined. The government is considering cutting or eliminating the “simply held it” portion while enlarging the “actually lived there” portion.

In short, even for the same home held the same length of time, the capital-gains burden would diverge much more depending on whether the owner actually lived there. Owner-occupiers would keep or strengthen their benefit, while those who held without living in the home would see their deduction shrink and face heavier tax on the gain.

How would the holding tax change?

On the holding side, the most powerful lever is adjusting the fair market value ratio within the comprehensive real estate tax. That ratio is multiplied against the published price minus the deductible amount to set the tax base; for housing it currently sits around 60%. Lifting it from 60% to, say, 80% would enlarge the tax base itself — effectively raising the holding tax even if nominal rates stay put.

What makes this lever notable is speed. The fair market value ratio sits in an enforcement decree, not statute, so the government can adjust it without parliamentary approval. Layer in higher published prices and the holding burden rises further. That said, some reports say the government is also weighing finer brackets for the comprehensive tax base to differentiate by tier.

When and how will it be decided?

The government plans to draft a blueprint for the tax bill late this month, based on interim results from a study on rationalizing the tax system. The holding- and capital-gains-tax directions are then expected to feature in a tax-reform package likely to be announced next month. Items adjustable by decree — like the fair market value ratio — could take effect relatively early, while items requiring statutory change would likely apply later, after parliamentary debate.

Market views on the intensity and timing are split. Some see a holding-tax hike nudging more listings onto the market and capping prices, while others argue the market impact will be short-lived. There’s also a view that the stronger the residence-based differentiation, the faster demand reshuffles toward “homes to actually live in.”

The bottom line

The direction is clear: redesign the tax burden around “is this a home you actually live in?” rather than “how long have you held it?” When the three threads — viewing acquisition-holding-disposal as one, trimming the mere-holding deduction, and raising the fair market value ratio — interlock, the cost of multiple-home and non-resident ownership clearly rises. Still, the exact size of the increases, the timing, and the pace for items that must clear parliament are not yet set. If you’re planning to buy or sell, it’s worth checking the late-month blueprint and next month’s tax package, then working out how the residence requirement and your holding/residence periods apply to your own situation.
