Registration, banking and utilities in Seoul

The Alien Registration Card

Foreign residents staying beyond a short period register with the immigration office and receive an ARC carrying a registration number. Appointments are booked through the HiKorea system and slots in Seoul get taken quickly, so book as soon as you have a date of arrival. The card and its number are what banks, mobile operators, hospitals and government services ask for.

• Book the immigration appointment through HiKorea in advance; walk-in capacity is limited.
• Bring your passport, photographs, the fee and whatever your employer or institution has issued you.
• Report a change of address at the local community service centre or immigration within the required window.
• Requirements change; confirm the current list with the Korea Immigration Service or your employer's HR before you travel.

Banking, phone and identity verification

A Korean bank account needs the ARC, a local address and usually an employment certificate, and new accounts are frequently opened with daily transfer limits until you can evidence income or a longer relationship. The mobile number is the other half of the key: most Korean services verify you by sending a code to a number registered in your own name, and a foreign SIM will not do. Get a prepaid number on arrival if you must, then move to a contract once the ARC exists.

• ARC, address proof and an employment certificate for the bank appointment.
• Expect low transfer limits on a new account until you upgrade the account grade.
• A phone contract in your own name unlocks identity verification for apps and ticketing.
• Naver and Kakao accounts, once verified, function as everyday login and payment identity.

Utilities, maintenance and bills

In most apartment buildings, electricity, water, heating and shared services are bundled into a monthly management fee billed by the building, with your own metered usage added on. In an officetel or a villa you may hold accounts directly. Korean electricity is charged on a progressive tariff that rises steeply with consumption, which makes an air-conditioned August materially more expensive than the other eleven months.

• Ask for the last twelve months of management fees before signing, not just the headline figure.
• Electricity pricing is progressive — summer bills rise faster than usage does.
• Bills are usually paid by automatic transfer from a Korean account.

Taxes and social insurance

Employees have income tax withheld through payroll and settle up in a year-end tax adjustment each January and February, where deductions for rent, medical costs and education are claimed. Employment also brings enrolment in the four national insurances covering pension, health, employment and industrial accident. Some countries have bilateral social security agreements affecting pension contributions, and lump-sum refunds of pension contributions on departure are available to nationals of some countries and not others.

• Year-end tax adjustment runs in January and February for the previous calendar year.
• Keep rent receipts and the registered lease — a rent deduction may be claimable.
• Pension refunds on leaving Korea depend on your nationality and any bilateral agreement.
• This is not tax advice; confirm your position with the National Tax Service or an accountant.
