5 Conditions and Hidden Costs to Check Before Signing a Virtual Office Contract
Beyond the monthly fee, here are the deposit, auto-renewal, cancellation penalty, VAT, and add-on service costs you must verify when signing a virtual office contract — with concrete figures for each.
When looking for a virtual office, most people compare only the monthly fee. But once you add up the deposit, VAT, early-termination penalties, and add-on service fees, even two products both listed at 30,000 won a month can differ by more than 65% in total first-year cost.
According to National Tax Service statistics, new business registrations in Korea numbered 1.276 million in 2023, and the virtual office market grew roughly 15% year over year. There are more options than ever, but because contract terms differ completely from one provider to the next, careful comparison before signing is essential.
In this article, we lay out the five key conditions you must check before signing a virtual office contract, and we show—with concrete pricing examples—how each one affects your actual cost. At the end, we also introduce CoworkCity's contract terms as seen through these same five criteria.
1. Why must you always check for hidden costs?
Nationwide, virtual office monthly fees run from 20,000 to 60,000 won. But once the following items are added, annual total cost can differ by more than twofold.
- Deposit of 100,000–200,000 won
- Early-termination penalty
- VAT of 10% (when listed separately)
- Add-on service fees for mail, phone, meeting rooms, etc.
The real one-year cost difference, by example
Even at the same listed price of 30,000 won a month, actual spending varies greatly depending on the contract terms.
Option A – 200,000 won deposit, VAT separate
- Monthly fee: 30,000 won × 1.1 (VAT) = 33,000 won
- One-year fee: 33,000 won × 12 months = 396,000 won
- Deposit: 200,000 won
- Actual first-year spending: 396,000 won + 200,000 won = 596,000 won
Option B – 0 won deposit, VAT included
- Monthly fee: 30,000 won (VAT included)
- One-year fee: 30,000 won × 12 months = 360,000 won
- Deposit: 0 won
- Actual first-year spending: 360,000 won
The difference between the two is 236,000 won, about 65%. The listed monthly fee is the same, but what you pay in the first year can diverge by more than 200,000 won depending on the contract terms.
CoworkCity charges no deposit, starts at 20,000 won a month, and includes VAT in every fee, so the displayed price is exactly the amount you pay.
2. How much deposit do you have to pay?
Virtual office deposits vary widely by provider, with a large range from 0 won to 3–12 times the monthly rent.
Deposit levels by provider type
- No deposit (0 won): virtual-office specialists such as CoworkCity, Doran SOHO, World Biztown
- Deposit of 100,000–200,000 won: many virtual office providers (refunded on move-out)
- Deposit = 3+ times monthly rent: premium shared offices
- Deposit = 10–12 times monthly rent: the traditional office-lease model
A deposit is money you get back on move-out, but be sure to check the following.
- Refund conditions: whether restoration costs are deducted from the deposit
- Refund timing: when it's returned after move-out (immediately / after 1 month / after 3 months, etc.)
- Deductions on early termination: whether there's a clause that deducts part of the deposit like a penalty
If this part is vague, the amount you get back can shrink significantly later when you terminate, as various charges are deducted from the deposit under one pretext or another.
CoworkCity requires a deposit of 0 won. With no separate prepayment, you can start using the service simply by paying the monthly fee.
3. Does the contract renew automatically?
Contrary to common industry assumption, most virtual offices do not renew automatically. When the contract period ends, the service terminates automatically, and unless the user separately requests renewal, it simply ends.
The problem is that when a virtual office used as a business registration address ends, your business registration address becomes invalid. If a user misses the expiration date, an address gap arises, and the tax office may even cancel the business registration on its own authority.
What problems arise if there's no automatic renewal?
- Missing the expiration date causes the virtual office address to expire immediately, invalidating the address on your business registration certificate
- A prolonged state of having no address risks the tax office canceling your registration on its own authority
- Missed receipt of important mail from the tax office, banks, and public institutions
- During the gap before recontracting, inability to issue tax invoices and other work disruptions
Items you must check in the contract
- Whether automatic renewal is provided: whether it auto-renews, or whether you must recontract each time
- Advance expiration notice: how many days/weeks before expiration they send a renewal notice
- Price changes on recontract: whether you can recontract at the same price, or whether there's room for increases
CoworkCity renews automatically through recurring billing, so no address gap arises from contract expiration (Terms of Service, Article 11(2)). Because your business registration address never lapses, you're safe from the risk of tax-office cancellation. At the same time, you're not locked into an annual commitment, so when you no longer need it you can easily request termination anytime within the service (Terms of Service, Article 8(3) and Article 11(4)). The full text is available in the CoworkCity Terms of Service.
4. Under what conditions does an early-termination penalty arise?
Virtual office early-termination penalties have no standard rule. Whatever is written in each provider's contract is all there is. In particular, the penalty structure varies depending on the commitment period and whether you prepaid.
Termination conditions by contract type
- Monthly auto-renewing contract
- → Usually no penalty if you give one month's notice.
- → If you miss the notice deadline, one additional month is charged.
- Annual prepaid contract
- → On early termination, no refund of the remaining period, or
- → only a partial refund after deducting a penalty (10–30% of the remaining fee).
- Commitment-discount contract
- → If you received a discount, on early termination the entire discount amount is clawed back, and
- → in some cases an additional separate penalty is also charged.
Under civil law, a penalty agreement is presumed to be a prearranged estimate of damages, and a court may reduce it if it's unfairly excessive. But disputes over small-value contracts rarely escalate that far, so carefully checking the termination conditions before signing in the first place is the safest approach.
CoworkCity has no separate early-termination penalty clause (Terms of Service, Article 11). Members may request cancellation of recurring billing at any time. However, if there are unpaid fees or late charges, a settlement is required, and to complete your withdrawal you must transfer your business registration address elsewhere or submit proof of business closure (Terms of Service, Article 14(2)). Any period during which the address transfer hasn't been completed is treated as a usage period and fees may continue to be charged, so before terminating you must first change your business registration address. Refunds for early termination follow CoworkCity's refund policy (Terms of Service, Article 11(6)). The cited clauses and the full refund policy are available on the CoworkCity Terms of Service page.
5. Is VAT included in the monthly fee?
Because a virtual office is a B2B transaction, listing VAT separately is common. Even if the website shows "30,000 won a month," the actual amount charged is 33,000 won with 10% VAT added.
Annual cost difference by VAT inclusion
- 30,000 won/month (VAT separate)
→ Actual monthly charge: 33,000 won
→ Annual: 33,000 won × 12 months = 396,000 won
- 30,000 won/month (VAT included)
→ Actual monthly charge: 30,000 won
→ Annual: 30,000 won × 12 months = 360,000 won
- Annual difference: 36,000 won
For a 50,000-won-a-month virtual office, the annual difference with VAT separate grows to as much as 60,000 won.
Under the basic guidelines of the Value-Added Tax Act, if the contract doesn't specify whether VAT is included or separate, it is deemed VAT-inclusive. So before signing, be sure to check the following.
- Whether the website, quote, and contract clearly state "VAT included" or "VAT separate"
- If you only got a verbal explanation, confirm it once more in writing via email or text
CoworkCity includes VAT in all fees. The price shown on the website is exactly the amount charged, with no additional tax added.
6. Are there no add-on service fees?
The scope of basic service at a virtual office differs by provider. Quite a few providers include only the business registration address in the monthly fee and charge separately for mail management, phone reception, meeting room use, and the like.
Basic inclusions vs. paid add-ons
- Business registration address: usually included as standard
- Mail receipt and storage: included by some providers, an extra 10,000–30,000 won/month at others
- Mail scanning and forwarding: usually 1,000–3,000 won per item, or an additional monthly flat fee
- Phone reception service: an extra 20,000–50,000 won/month
- Meeting room use: an extra 10,000–30,000 won per hour
- Tax-agent referral: a separate fee (free referral at some providers)
Even if the monthly fee looks cheap, adding mail management and phone reception can push the effective monthly cost up to 50,000–100,000 won.
So before signing, check the following.
- Organize which services your business actually needs.
- Confirm whether each is included as standard or a paid option.
- If it's a paid option, confirm whether it's a monthly flat fee or per-item billing.
CoworkCity includes the business registration address and mail management service as standard. You can receive alerts when mail arrives, and use a forwarding service as needed.
7. How are CoworkCity's contract terms different?
Summarizing CoworkCity's contract terms against the five concern points above gives the following.
- Deposit: 0 won (no separate prepayment)
- Fee: from 20,000 won a month (with annual billing), at VAT-inclusive prices
- Contract type: recurring-billing auto-renewal, no forced annual commitment
- Termination conditions: no separate early-termination penalty clause; you can request cancellation of recurring billing anytime (early-termination refunds follow the refund policy)
(However, settlement of any unpaid balance and transfer of your business registration address—or proof of business closure—are required.)
- Add-on services: mail management included as standard
- Contract process: instant access to the contract via electronic contract
- Nationwide branches: business registration possible at 180+ branches
- Business-registration safeguard: if your business registration is rejected, we support the branch-change procedure free of charge and, if the user wishes, operate a 100% refund program
CoworkCity has no costs beyond the displayed price, so you don't have to worry about hidden costs before or after signing. With the electronic contract system, you can review the contract instantly, reducing the risk of overlooking auto-renewal or penalty clauses.
8. In closing — compare "total cost," not the monthly fee
A virtual office contract is not a matter of comparing just the monthly fee.
Be sure to look at these five things together.
- Deposit: how much it is, and when and under what conditions you get it back
- Auto-renewal: the termination-notice deadline and the renewal conditions
- Early-termination penalty: in what situations, and how much, you'll be charged
- VAT inclusion: whether the listed amount is the actual amount charged
- Add-on service fees: whether mail, phone, meeting rooms, etc. are included as standard
If you check these five items one by one like a checklist before signing, you can avoid most unexpected costs.
CoworkCity offers transparent contract terms: 0 won deposit, VAT included, and no early-termination penalty clause. You can use a virtual office at 180+ branches nationwide from 20,000 won a month (on an annual-billing basis), and if your business registration is rejected, you're safely protected by the branch-change procedure or the 100% refund program.
Pre-contract checklist for a virtual office (summary)
- I've checked the deposit amount and refund conditions.
- I've checked the auto-renewal terms and the termination-notice deadline.
- I've checked the conditions and amount of any early-termination penalty.
- I've checked whether VAT is included in or separate from the monthly fee.
- I've checked the add-on fees for services I need, such as mail, phone, and meeting rooms.
Checking just these five things can save you hundreds of thousands of won in unnecessary first-year spending.
