In recent years, the rapid expansion of shared offices has led to a significant increase in cases where multiple businesses register at the same address. This trend is particularly prevalent among startups, freelancers, and solo entrepreneurs who prefer shared offices due to their cost-effectiveness and flexibility. In some cases, dozens or even hundreds of business registrations occur within a single building. However, this phenomenon raises several legal and practical issues, such as suspicions of fictitious business registrations by the National Tax Service (NTS) and increased risk of tax audits. Therefore, entrepreneurs must exercise caution.
Current Status of Multiple Business Registrations in Shared Offices
Shared offices are increasingly favored by business owners due to flexible lease terms, reduced costs, and convenient locations. However, when many businesses are registered at the same address, the NTS may suspect whether the location is a genuine place of business and whether there is a substantive business operation. With the rise of remote startups and online businesses, the issue of “ghost companies” and “fictitious businesses” without real operations has emerged as a major concern.
NTS Standards for Business Registration and Practical Issues
The NTS primarily evaluates the existence of an actual business premises when reviewing business registration applications. The key standards include:
- The location must be the actual place of business, not merely for mail receipt or name lending.
- Applicants may be required to submit supporting documents such as lease agreements, photos of the premises, layout plans, access cards, and office equipment.
- If many businesses are registered at the same address, the NTS may conduct on-site inspections to verify actual business activity.
Common practical issues include:
- If the lease agreement provided by the shared office operator offers “non-designated seating” instead of a fixed space, it may be difficult to prove the existence of a real business.
- If tens or hundreds of businesses are registered in the same office space, the NTS may conduct a full or sample audit of all businesses at that address.
- If the business owner does not physically work at the address or does not use the office space, the registration may be deemed fictitious.
Fictitious Business Suspicion Cases and On-Site Inspections
The NTS is intensifying oversight of fictitious business registrations occurring in shared or virtual offices. Common red flags include:
- Over 100 businesses registered at the same address, but fewer than 10 people are actually present during a site visit.
- The address listed on the business registration certificate only has a mailbox, with no actual office, furniture, or personnel.
- The name on the lease agreement does not match the name on the business registration.
When such issues are identified, the tax office conducts on-site investigations focusing on:
- Verification of actual office use (presence of computers, telephones, furniture, etc.)
- Presence of staff at the location
- Validity of the lease agreement and utility bill records
- External signs of the business (signboards, nameplates, etc.)
If no evidence of actual office use is found, the NTS may cancel the business registration, deny VAT refunds, and impose penalties.
Tax Audit Risks and Legal Liabilities
Registering multiple businesses at a shared office significantly increases the risk of tax audits. The NTS routinely investigates suspected fictitious or name-lending businesses. If a business is found to be fictitious, the following penalties may apply:
- Cancellation of business registration and denial of VAT refunds
- Imposition of penalties and back taxes for false or unreported filings
- Criminal charges under the Framework Act on National Taxes (e.g., imprisonment, fines)
- Lease contract termination and potential civil lawsuits for damages
Recently, the NTS has begun using big data analytics to identify suspicious businesses registered at the same address and has ramped up both random and comprehensive audits.
Precautions for Shared Office Operators
Shared office operators must take proactive steps to avoid legal liability:
- Clearly document actual office usage and space allocation in lease agreements with tenants.
- Regularly verify the presence and activity of registered businesses.
- Implement pre-screening procedures to confirm the legitimacy of the tenant’s business (e.g., business plans, funding sources).
- Be prepared to promptly submit lease agreements, access records, and payment documentation upon NTS request.
Practical Checklist for Individual Business Owners
If you are planning to register a business at a shared office, consider the following:
- Prepare objective evidence to prove actual office use and business activity.
- Ensure the lease agreement clearly states your name, the space you are using, and the lease period.
- Install signage, nameplates, or other visible indicators of your business at the premises.
- Maintain tangible traces of business activity, such as office equipment, computers, and files.
- Cooperate fully with the NTS in case of on-site inspections and provide accurate documentation.
Tax Risk Case Studies
- A solo entrepreneur (Mr. A) registered a business in a shared office and applied for a VAT refund. However, an on-site inspection revealed no signs of office use, leading to refund denial and cancellation of the business registration.
- In another case, 50 businesses registered at the same address were subject to a sample audit. Ten businesses found not to be operating were penalized with back taxes and fines.
- Some shared office operators have been criminally charged for facilitating fictitious registrations by forging lease documents.
These examples show that registering multiple businesses at a shared office is not merely a matter of convenience; it poses real legal and tax risks that must be carefully evaluated.
Key Legal Terms and Definitions
- Business Registration: Required procedure under the Framework Act on National Taxes and the Value-Added Tax Act, requiring verification of actual business premises.
- Substance Over Form Principle: Taxation based on the actual substance rather than formalities; if no real business exists, the registration may be deemed fictitious.
- Fictitious Business: A business that is registered without engaging in actual business activities; subject to cancellation, penalties, and criminal prosecution.
- On-Site Verification: Direct inspection by the NTS to verify the existence of a business at the registered address.
- Lease Agreement: Essential document for registration that must include the tenant’s name, the space used, and lease terms.

For Shared Office Business Registrations:
- Can you prove actual business activity at the location?
- Do you have necessary supporting documents (lease agreement, photos, access logs)?
- Are too many businesses registered at the same address?
- Are you prepared for an NTS on-site audit?

For Shared Office Operators:
- Are lease terms and actual usage clearly documented?

Conclusion
While registering a business at a shared office offers convenience and cost savings, it also introduces significant legal and tax risks. Ensuring the presence of a real business operation and maintaining robust documentation are critical. Both shared office operators and tenants must proactively manage these risks to avoid unnecessary audits and legal disputes.
