The Final Checklist You Must Review After Relocating Your Place of Business
We've laid out the administrative steps to handle after relocating your place of business at a glance. From changing the address on your business registration certificate to the 4 major insurances and mail handling — check the items that can trigger penalties if missed, in checklist form.
Editor's Note When you run a business, you end up relocating your place of business for all kinds of reasons. To find a better location, or because of the rent burden in high-rent areas like Gangnam, Mapo, or Seongsu, or to expand the business. But when you actually start preparing for the move, a sense of being overwhelmed sets in — "Where do I even start?" That's because it doesn't end with just moving your stuff; there are more legal procedures to handle than you'd think.
In this article, we've put together the administrative procedures you absolutely need to check when changing your business address, along with the practical items you should take care of.
ℹ️ Q. How do I change my business registration address?
If you've relocated your place of business, the first thing to do is change the address on your business registration certificate. You need to update the business information registered with the National Tax Service to the new address, and you should be careful — handling this procedure late can result in penalty taxes.
How to apply online
- Access the National Tax Service Hometax
- Certificate/Registration/Application 👉 Select the Business Registration Application/Correction/Closure menu
- Click Business Registration Correction (Change) Report
- Enter the changed address and submit
How to apply offline
- Visit the competent tax office
- Fill out and submit a business registration correction report
- A copy of the new lease agreement is required
- Filing deadline: within 20 days of the date the place of business is relocated
If you miss the deadline, a business-registration noncompliance penalty tax (1% of the supply value, minimum 50,000 won) may be imposed, so it's best to handle it as soon as possible after the move.
ℹ️ Q. What if my competent tax office changes?
How a business address change is processed can differ depending on which area you move to. For example, when the district (gu) changes — such as from Gangnam-gu to Seongdong-gu in Seoul, or from Mapo-gu to Yeongdeungpo-gu — there's a high chance the competent tax office will be different.
There are also cases where the competent tax office changes when you relocate your place of business. For example, moving from Gangnam to Seongdong-gu in Seoul. In such cases, you may need not a simple address correction, but a procedure of closing the existing business and registering a new one.
Procedure when the competent tax office changes
- File a closure report with the existing competent tax office
- Apply for business registration at the new competent tax office
- A new business registration number is issued
In this case, because your business registration number changes, you have to separately notify clients, banks, card companies, and the like of the number change. It means more to keep track of than relocating within the jurisdiction of the same tax office.
ℹ️ Q. How do I change the workplace information for the four major insurances?
If you employ staff, you also need to change the workplace address for the four major insurances.
How to change it • Access the Four Major Social Insurance Information Linkage Center (www.4insure.or.kr)
• Use the workplace address change report menu
• Health insurance, national pension, employment insurance, and industrial accident insurance can all be changed at once
If the jurisdiction changes, the person in charge at the National Health Insurance Service or the Korea Workers' Compensation & Welfare Service may change, so you may get a confirmation call after the move.
ℹ️ Q. How do I handle mail and parcels?
It's a problem when you've changed your address but important documents get delivered to the old one. It's best to organize this systematically.
✔️ Mail handling checklist ✅ Apply for the post office's "mail holding and forwarding service" (up to 1 year) ✅ Change the address for receiving tax notices (Hometax, Wetax) ✅ Change your address at financial institutions (banks, card companies, securities firms, etc.) ✅ Check the email address for receiving electronic tax invoices ✅ Change your address with courier companies
✔️ Additional checks if you run an online shopping mall • Naver Smart Store: Edit seller information • Coupang, 11st, etc.: Change the settlement address and return address • Your own mall: Update company info and the exchange/return address
ℹ️ Q. What are the final checks after the move?
Finishing all the procedures isn't the end. You need to verify that the changes were actually reflected properly.
Final check list ✅ Confirm mail arrives normally at the new address ✅ Confirm the address is reflected in online map services ✅ Update the address on business cards, your website, and social media profiles ✅ Change the address for utilities like electricity, water, and gas ✅ Check signage and place-of-business markings ✅ Re-notify clients and partner companies that the change is complete
In particular, it's a good idea to monitor for 2-3 months whether electronic tax invoices and tax notices arrive properly at the new address.
✅ Key summary ✅ Essential procedures when changing your business address ✅ 1. Change business registration address, within 20 days of the move ✅ 2. Change corporate registration (for corporations): within 2 weeks ✅ 3. Change workplace info for the four major insurances ✅ 4. Change the receiving address for mail and tax notices ✅ 5. Update online maps and customer notices ✅ 6. Change the address with clients and financial institutions
⚠️ ※ Cautions ※ ⚠️ • When the competent tax office changes, the business registration number changes too ⚠️ • If not filed within the deadline, a penalty tax is imposed (1% of the supply value, minimum 50,000 won)
Relocating a place of business isn't simply moving locations — it's work that comes bundled with various administrative procedures and customer management. If you build a checklist and go through it one item at a time without missing anything, you can wrap it up far less complicated than you'd expect.
If you run an online business, work freelance, or run a one-person company where a physical office isn't strictly necessary, using a virtual office to change your business address is also well worth considering. If you want to reduce relocation costs or rent burden while still handling the administrative procedures reliably, this kind of alternative address-change method is worth a look at least once.
