Qu'est-ce que Korea Housing Subscription Account (청약통장)?

▾

The 주택청약종합저축 (Jutaek Cheongyak Jonghap Jeochuk — Comprehensive Housing Subscription Savings Account) is a government-backed savings and lottery-based system in South Korea that grants eligible participants the right to apply for both public housing (국민주택, 국민임대주택) and private housing (민영주택) at potentially below-market prices. The account combines subscription rights for all types of Korean housing in a single account, replacing the previous separate accounts for different housing types. Monthly deposits range from KRW 20,000 to KRW 500,000 and accumulate over time to build subscription points and the minimum deposit requirement for housing applications. Public housing subscriptions (국민주택) are allocated based on points (가점제) that consider: family size and dependents (up to 32 points — larger families score more), years of consecutive non-homeownership (up to 32 points), and the length of the subscription account (up to 17 points, maximum at 15 years). Public housing also has a special supply category (특별공급) for newlyweds, multi-child families, first-time buyers, and public officials. Private housing lotteries (민영주택) are allocated partly by lottery and partly by points, depending on location and type. The housing subscription account holder can deduct up to KRW 2.4 million per year from taxable income (subject to income conditions — typically applicable to wage earners without homeownership earning below a threshold), providing a modest annual tax benefit. Upon cancellation (해지), the account balance plus accumulated interest is returned — the account does not lock in funds permanently.

Comment Korea Housing Subscription Account (청약통장)

▾
  1. 1Open a housing subscription account at any participating bank — initial deposit as low as KRW 10,000.
  2. 2Set a monthly contribution between KRW 20,000 and KRW 500,000 — consistent monthly contributions build subscription period points.
  3. 3Track points: each year without homeownership adds subscription period points; family members add family points at the time of application.
  4. 4Apply for housing subscriptions through the applicable developer or public housing authority when units are offered.
  5. 5For public housing, points determine ranking — higher points increase the probability of selection.
  6. 6For private housing in non-overheated areas, additional point-based allocation uses the subscription score.
  7. 7Claim the annual income deduction of up to KRW 2.4 million on contributions when filing the annual comprehensive income tax return if eligible.

Exemples résolus

▾
Exemple 1Maximum Points Calculation
Donné:Family of 4 (32 family points); 10 years without homeownership (28 non-ownership points); 15-year subscription (17 period points)
Résultat:Total points: 77 out of maximum 81

High points greatly improve chances in point-based public housing applications

Family 32 + non-ownership 28 + subscription period 17 = 77 points. Maximum possible = 81.

Exemple 2Annual Tax Deduction
Donné:Annual contributions KRW 2,400,000; wage earner, first-time buyer eligible
Résultat:Income deduction: KRW 960,000; tax saving approximately KRW 158,400

Deduction = contributions × 40%, max deduction base KRW 2.4M; saving depends on marginal tax rate

KRW 2.4M × 40% = KRW 960,000 income deduction. At 16.5% effective rate: KRW 960K × 16.5% = KRW 158,400 tax saving.

Exemple 3Subscription Period Points by Duration
Donné:Account opened 8 years ago
Résultat:Subscription period points: approximately 10-12 (scale increases by 1 point per year up to 17 at 15 years)

Points accumulate annually with consistent monthly deposits; maintaining the account is key

The subscription period point schedule awards approximately 1-2 points per year of account maintenance with regular deposits.

Exemple 4Non-Homeownership Year Points
Donné:Applicant has not owned a home for 5 years since age 30
Résultat:Approximately 10 non-homeownership points

Non-homeownership points max at 32 after 15 years; this category heavily rewards those who delayed homeownership

5 years without homeownership earns approximately 10 points. Each additional year adds 2-3 points toward the 32-point maximum.

Questions fréquentes

▾
Q

What is the housing subscription account (청약통장)?

A

The 주택청약종합저축 is a savings account specifically designed to qualify holders to apply for new housing subscriptions in Korea. It accumulates both monetary deposits (needed to meet minimum deposit requirements for applications) and subscription points (used for competitive allocation). It is widely considered an essential first step in Korean homeownership planning.

Q

What happens if I withdraw from the account?

A

If you close (해지) the housing subscription account before using it for a successful application, you receive the balance plus accumulated interest. However, closing the account permanently removes your accumulated points — you would start at zero points if you later open a new account. The subscription period is lost upon closure.

Q

How are family points calculated?

A

Family points are based on the number of dependents at the time of application: 0 dependents = 0 family points; 1 dependent = 5 points; 2 = 10; 3 = 15; 4 = 20; 5 = 25; 6 = 27; 7+ = 32 points (maximum). Dependents are typically spouses and minor children listed in the household registration.

Q

What is the 1+1 special supply?

A

Korea Housing Subscription is a specialized calculation tool designed to help users compute and analyze key metrics in the finance and investment domain. It takes specific numeric inputs — typically drawn from real-world data such as measurements, rates, or quantities — and applies a validated mathematical formula to produce actionable results. The tool is valuable because it eliminates manual calculation errors, provides instant feedback when exploring different scenarios, and serves as both a decision-support instrument for professionals and a learning aid for students studying the underlying principles.

Q

Can I apply for housing in areas where I don't live?

A

Generally, applicants must have been residents of the region or metropolitan area where the housing is located for a minimum period (typically 2 years for Seoul). Some types of housing may have regional residency requirements that restrict applications to local residents. Always check the specific notice (모집공고) for each housing subscription.

Q

How does the special supply for multiple children work?

A

Families with 3 or more children (다자녀 특별공급) receive a priority allocation in both public and private housing subscriptions. This policy is part of Korea's pro-natalist measures to encourage larger families. Multi-child families are given priority over the general allocation, often with a separate pool of units reserved exclusively for them.

Erreurs courantes à éviter

▾
  • !Closing the account prematurely and losing all accumulated subscription period points — this is an irreversible decision with significant long-term cost.
  • !Contributing less than the optimal monthly amount to accumulate maximum subscription period points — consistent regular deposits are required.
  • !Not claiming the annual income deduction on housing subscription contributions — eligible first-time buyers miss KRW 100,000-200,000 in annual tax savings.
  • !Applying for housing subscriptions in areas where residency requirements are not met — failed applications waste subscription opportunities.
  • !Not understanding that points reset to zero if you ever own a home and then sell it — non-homeownership is calculated cumulatively but once ownership occurs the clock may restart.
  • !Assuming the lottery is purely random — the point-based system in public housing means higher points provide a significant competitive advantage.
💡

Conseil Pro

Open a housing subscription account as early as possible — ideally in your early 20s. Every year the account is active, subscription period points accumulate. By age 35 with 12-15 years of account history, you can have maximum subscription period points (17), which provides a meaningful competitive advantage in public housing applications.

Le saviez-vous?

Korea's housing subscription system is one of the world's most extensive government-managed housing lottery programs. At peak popularity in 2021, single Seoul apartment subscription events attracted over 100,000 applicants for a few hundred units — implying odds worse than 1 in 200. Despite the long odds, over 25 million Koreans maintain active housing subscription accounts — nearly half the total population.
