Korea contract penalty rules follow the same 3-layer structure across telecom, rental, and subscription services. If you live in Korea you will keep hearing words like “약정 (commitment),” “해지 (cancellation),” and “위약금 (penalty fee)” — this guide pulls the core of the Korea contract penalty across telecom, housing, and subscriptions into one short read.

Why Korea has so many contracts: discount = promise

If you live in Korea, you have probably seen this:

• Opening a phone line with a 1- or 2-year commitment
• Installing internet with a 3-year commitment + free gifts
• Signing up for an OTT/app and getting hit with auto-renewing recurring billing
• A standard rental of 2 years + a deposit

And the moment you try to cancel, you see these words:

Penalty / Discount clawback / Gift return / Early termination

This is not Korea being unusually cold — the structure is almost the same everywhere. For more on consumer protection, see Financial Supervisory Service.

One-line summary:

• Carriers and landlords give you discounts and benefits in exchange for a long commitment, and
• If you don’t fulfill that commitment, you “give back” those benefits. (m.smartchoice.or.kr)

SmartChoice (Korea’s official telecom consumer info portal) explains it the same way: if you receive contract benefits (rate discount or device subsidy) and break the contract, a discount clawback (penalty) applies. (m.smartchoice.or.kr)

Korea penalty 3-layer structure (telecom, housing, subscription)

Cancellation costs in Korea are usually a mix of these 3 layers. Related: Foreign credit score in Korea: how to build credit.

1. Pay for what you used

• Current month bill, days used after installation, daily-prorated charges

2. Return the benefits you received (this is the key)

• Rate discounts, device subsidies, free gifts, waived installation fees

3. Pay any remaining principal/obligation

• Remaining device installments, lease balance, etc.

Contract type	Main penalty items	When penalty can be waived	Source
Mobile commitment	Discount clawback + remaining device installments	Move to area without service, etc.	SmartChoice
Internet/TV	Rate discount + gift return + install fee	Near end of term / re-sign with same carrier	WiseUser
Rental	Earnest money / remaining rent / agent fee	3 months after notice on tacit renewal	Housing Lease Protection Act
Subscription	Remaining commitment / digital content used	7-day cooling-off (conditional)	E-Commerce Act Art. 17

1) Telecom (mobile) Korea contract penalty: service plan and device installments are separate

1-1. Master the key terms and you are halfway done

For the 7-day rule on online sales (e-commerce), see Easy Law.

• Commitment (약정) = “I will use this service for N years.” In return, the carrier reduces your rate or subsidizes your device. (Easy Law)
• Discount clawback / penalty = the portion of those benefits you have to give back if you break the commitment early. (SmartChoice)
• Device installments are a separate purchase contract from the service plan. Cancelling service does not erase what you still owe on the phone.

1-2. Why does the “Selective Commitment 25%” discount create a penalty?

Selective Commitment 25% gives you a 25% rate discount in exchange for a 1-year or 2-year commitment. If you break the contract early, the cumulative discount up to that month becomes a clawback. (SmartChoice)

1-3. Safest way to check the penalty before you cancel

Carriers usually let you check the discount clawback (penalty) and remaining commitment in their app or by calling customer service. (SK Telecom T World FAQ)

1-4. The mistake foreigners make most: “If I cancel, the device installments end too”

Cancelling service does NOT erase device installments. Even after you switch carriers, you usually still pay the remaining device balance to the original carrier. (LG U+ MVNO support)

1-5. Are there cases where the penalty can be waived or reduced?

Yes, in limited cases — moving to an area with no service, certain hardships, or near the end of the commitment when the remaining penalty is small. Documentation is usually required. (Easy Law)

1-6. Final check after cancellation: telecom unrefunded balance

After you cancel, check whether you have an unrefunded balance (overpaid). You can search at SmartChoice’s refund inquiry. (SmartChoice refund)

2) Internet/TV Korea contract penalty: gift returns are the real bomb

2-1. Core rules from WiseUser (official user portal)

Internet/TV contracts often layer on free gifts and waived installation fees, which become return obligations on early cancellation. WiseUser publishes the standard formulas. (WiseUser)

2-2. 5 questions to ask the carrier before you cancel

Copy and paste these on a call or chat to make the bill itemized:

• Please itemize the cancellation charges (discount clawback / install fee / equipment / gift).
• Please confirm whether the gift return is a separate side-agreement based on the contract. (WiseUser)
• How many days are left on the commitment, and what is the penalty if I cancel today?
• If I move and there is no service in the new area, can the penalty be waived?
• Can you email me the breakdown so I have a record?

3) Rental Korea contract penalty: bigger money than telecom

3-1. Earnest money vs. security deposit are NOT the same

Earnest money (계약금) is paid at signing as proof of intent. Security deposit (보증금) is the much larger lump-sum that secures the lease. Civil Code Art. 565 lets a buyer/seller back out before performance starts, by forfeiting earnest money or returning double. (Law.go)

3-2. Reality of mid-term rental cancellation: negotiation or replacement tenant

Outside tacit renewal, breaking a fixed-term lease usually requires the landlord’s agreement or finding a replacement tenant who takes over the contract. Easy Law summarizes the process. (Easy Law)

3-3. Tacit renewal changes the rules (very important for foreigners)

The Housing Lease Protection Act lets the tenant terminate during a tacit renewal, with the termination taking effect 3 months after the landlord receives notice. (Law.go) Supreme Court guidance has clarified the timing of effect. (Supreme Court)

3-4. Lease termination notice template (registered mail / email / SMS)

Use this minimal template so the date of receipt is clear:

Subject: Notice of lease termination
From: [Name, Address, Phone]
To: [Landlord name]
Re: Lease at [address], signed [date]
Body: I hereby give notice that I am terminating the above lease. Per the Housing Lease Protection Act, on a tacit-renewal contract this termination takes effect 3 months after you receive this notice. Please confirm receipt and the move-out / deposit-refund schedule.
Date / Signature

4) Subscription Korea contract penalty: 7-day cooling-off you should not miss

4-1. Online (e-commerce) subscriptions: 7 days is the default

The E-Commerce Consumer Protection Act Art. 17 grants a 7-day right of withdrawal for online purchases, with exceptions (digital content already started, etc.). (Law.go)

4-2. Gym/Pilates/lessons (offline subscriptions) have a different refund formula

Offline service contracts use the standard “used portion + administrative fee (capped)” calculation, not the 7-day e-commerce rule.

4-3. Subscription cancellation request template (email/chat)

Subject: Cancellation and refund request
I’d like to cancel [service] effective [date]. Please confirm: (1) the cancellation date, (2) the refund amount, (3) any deduction for “used portion” with the calculation, and (4) cancellation of any auto-renewal. I’m exercising the 7-day right of withdrawal under the E-Commerce Consumer Protection Act if applicable.

5) 30-second checklist before you sign any Korea contract

5-1. Six must-checks before signing

1. Commitment length (months/years) and exact end date
2. Penalty formula (discount clawback + gift + installment + install fee)
3. “Free gift” return obligation — is it written into the contract?
4. Move-out / area-no-service waiver clause
5. Auto-renewal terms and how to opt out
6. Refund window and itemized billing on request

6) Where to go when there is a dispute (official channels)

Korea contract penalty FAQ

Q1. Why is a 2-year commitment standard at Korean carriers?

It is the most common bundle of “device subsidy + rate discount” the carriers offer. SmartChoice explains the official subsidy structure. (SmartChoice)

Q2. If I cancel my line, do device installments disappear too?

No. Device installments are a separate purchase contract; the unpaid balance is due to the carrier. (U+ MVNO)

Q3. If I cancel internet, do I always have to return the free gifts?

Almost always, yes. WiseUser publishes the prorated formula carriers use. (WiseUser)

Q4. Does early termination of a rental always mean forfeiting the earnest money?

It depends. Civil Code Art. 565 covers earnest money on sale contracts. (Law.go) For leases the outcome depends on the contract form and renewal status. (Easy Law)

Q5. Can a tenant cancel a tacitly renewed lease anytime?

The tenant can give notice, and termination takes effect 3 months after the landlord receives the notice. (Law.go)

Q6. Are subscriptions always refundable within 7 days?

The E-Commerce Act Art. 17 sets the 7-day rule but carves out exceptions like digital content already provided. (Law.go)

Q7. Where do I file a complaint about refund or penalty?

General consumer disputes: 1372 Consumer Counseling Center. (Korea Consumer Agency) Telecom disputes: Telecommunications Dispute Resolution Committee. (TDRC)
