Income Amount Certificate Guide

At a glance

• The Income Amount Certificate is a service through which a person with global income, year-end settled income or daily-wage income gets the income amount of taxed income certified (Gov24 service guide).
• Ways to apply: online, in person, civil-service mail, mobile, unmanned kiosk.
• There is no fee (free), and processing is immediate (within 3 hours during working hours).
• You can also request an English certificate; in that case your passport must be checked.

Who needs to do this

• The person who filed global income tax or has taxed income such as year-end settled or daily-wage income applies.
• A representative can also apply, but representatives cannot apply online (internet or mobile) (Gov24 service guide).
• Foreigners in a status of stay that allows employment write their annual income amount on the integrated application form when applying for stay permits, and submitting the Income Amount Certificate is waived through data linkage with the National Tax Service (Ministry of Justice guide manual for foreigners' stay).
• However, depending on the status of stay or the item being reviewed, you may be asked to submit an Income Amount Certificate issued by the tax office separately, so check the documents for your status.

Where to apply

• Online: apply on Hometax or Gov24. Certificates issued online through Gov24 can be viewed under MyGOV > My applications > Service applications.
• In person: tax office civil-service desk. Gov24 also lists cities, counties, districts, towns, townships and neighborhoods as receiving offices, and asks you to confirm with that office whether it actually accepts the application.
• You can also apply by civil-service mail or at an unmanned kiosk.
• Enquiries: National Tax Service 126 (no area code).

What to bring

• Applying yourself: show 1 valid ID (resident registration card, driver's license, residence card, passport, etc.).
• Applying through a representative: letter of authorization, the representative's ID, and the principal's ID (for a corporation, 1 of: seal certificate, registered seal-use form, or representative's ID).
• According to Gov24 there is no separate application form.
• English certificate: the official checks your passport information through administrative information sharing; if you do not consent, you submit it yourself.

Cost

• There is no issuance fee (free; Gov24 service guide states "no fee").
• Processing is immediate (within 3 hours during working hours).

Procedure

• Step 1: Check which year's Income Amount Certificate the receiving office (e.g. the immigration office) requires.
• Step 2: Choose how to apply. Only the person themselves can apply online (internet or mobile).
• Step 3: When applying in person, show your ID; a representative also shows the letter of authorization and the principal's ID.
• Step 4: Receive it immediately and submit it to the receiving office.

Common sticking points

• The global income tax final return period is from May 1 to May 31 of the following year. The Ministry of Justice manual assumes that the previous year's Income Amount Certificate may not be issued until filing ends in May, and during that period accepts the certificate for the year before.
• Some review standards in principle accept only the Income Amount Certificate issued by the National Tax Service as proof of income (Ministry of Justice guide manual for foreigners' stay).
• A representative cannot apply online.
• Income that was not reported does not appear. The Income Amount Certificate certifies taxed income.
