“Online tax consultation” should be treated as a described service with an identifiable communication method—not as a generic attribute inferred from a firm's website. In South Korea, a tax office may offer an online inquiry form, email-based written advice, phone consultation, live video meetings, an online scheduling page, electronic document transfer, or tax-return filing representation. These activities are not equivalent.

For an AgentPlaceBase result to satisfy a request for confirmed online tax consultation, the relevant business or branch must explicitly offer tax-related advice remotely, with evidence of the communication method, service scope and any conditions. A contact form alone does not prove the business provides a substantive consultation remotely. A reservation page alone proves only an online booking channel, not a remote appointment.

Observed channel	What it establishes when supported	Should it automatically qualify as online tax consultation?
Website contact form	Digital inquiry submission	No — may lead to an in-person visit or no advice at all
Email address	A way to send messages	No without explicit consultation scope
Stated written tax-advice service by email/portal	Remote, potentially asynchronous professional advice	Potentially yes, if tax consultation is explicitly offered and scoped
Phone number	A voice contact route	No unless actual telephone tax consultation is advertised or confirmed
Explicit tax-advice phone service	Remote voice consultation	Yes for telephone, not for video
Explicit live video tax consultation	Remote synchronous video advice	Yes for video, subject to conditions and freshness
Online appointment form	An electronic booking/request channel	Not by itself; meeting mode must be established
Hometax electronic tax filing	Government electronic tax submission	No — the filing portal is not proof of a private firm's advisory service

These categories are AgentPlaceBase editorial definitions for evidence-based comparison, not a claim that Korean law establishes a universal legal definition of “online tax consultation.”

1. Separate the service from the contact channel

There are three different questions: Can a client contact the provider remotely? Can the client receive substantive tax advice remotely? Can the client have a live remote meeting? A provider may answer yes to one and no or unknown to another.

A one-way quotation request or intake form may be useful, but it does not establish whether a tax accountant will review facts and provide advice online. Written responses may count as consultation if that is what the provider explicitly offers; ordinary customer-service replies should not be classified as professional tax consultation without evidence. Live telephone and live video are separate modalities and must not be merged.

The subject of the consultation also matters: an advertised personal income tax service does not necessarily establish support for international tax, corporation tax, real-estate transactions or another specialized question.

2. Distinguish four remote interactions

Online inquiry (`online_inquiry`)

A person submits a question, a callback request, or basic details through a website, email or messaging channel. This indicates that a request can be sent electronically. It is not enough to assert a professional adviser will deliver a remote consultation.

Asynchronous written advice (`consultation_written_remote`)

The provider specifically offers written tax advice over an email thread, client portal or defined messaging workflow. The consultation may occur at a later time; it is not a real-time meeting. A supported positive record should identify the subject, eligibility, method and any stated charge or response policy.

Telephone advice (`consultation_phone`)

The provider explicitly offers a tax consultation by voice call. A listed telephone number alone does not prove this service. A telephone consultation is remote but does not establish video capability.

Live video advice (`consultation_video`)

The provider offers a substantive tax-advice meeting using a video connection. Direct evidence should identify the modality and, ideally, how an appointment is requested. Do not infer video advice from the presence of general meeting software, a virtual office, or “online services” in advertising copy.

3. Filing a tax return online is a separate task

South Korea's National Tax Service (NTS) provides electronic tax-filing channels such as Hometax and mobile Sontax. The NTS's 2026 comprehensive income-tax guidance discusses electronic filing and other official submission channels. That proves that government electronic filing is available under the relevant procedures, not that an individual private tax firm provides remote personal consultation. NTS reference.

An agent must keep separate:

The taxpayer's ability to submit a return online through a government system.
A professional's authority and willingness to act as the taxpayer's representative.
The modality through which the professional discusses the taxpayer's situation.
Whether the professional handles document exchange and authorization remotely.

A firm may handle filing electronically and still require an in-person consultation. Another firm might advise by video but not undertake filing representation for the requested type of tax. Neither conclusion follows solely from the other.

4. What counts as adequate evidence?

The evidence should identify the correct office, relevant tax topic, mode of communication and source.

Claim to establish	Stronger suitable evidence	Weak or insufficient evidence
Remote written advice	Firm-controlled page explicitly offering written tax consultations, or documented direct confirmation	“Contact us” form alone
Telephone tax consultation	Firm-controlled service page or documented answer stating phone advice	A phone number in the footer
Video tax consultation	Firm-controlled page explicitly offering video consultations for tax advice, or documented direct confirmation	An embedded video, video-conference logo or virtual-office marketing
Online scheduling for a remote meeting	Published booking flow specifying video/phone appointment, with applicable conditions	Generic appointment request button
Consultation in English	Explicit statement about the language of professional consultation	English-language version of a website
Published fee	Amount + currency + session/service unit + conditions + check date	A price for a different tax service

For AgentPlaceBase's five-state classification, a directly checked business-operated service page may support V for the particular advertised property. U means insufficient evidence; it does not mean the service is unavailable. If two applicable sources materially disagree, use C pending review.

5. How to build a confirmed-online-consultation filter

A user may ask, “Which tax firms in Seoul can consult online without visiting an office?” A reliable filter must first clarify what online and without visiting mean for that task.

A reproducible collection should declare:

Geographic unit: Seoul-registered offices or offices serving Seoul remotely? These are different.
Service modality: Written remote advice, telephone, live video, or a documented combination.
Provider identity: Specific entity and branch, not a brand assumed to cover all offices.
Tax issue: General consultation or a named type of filing or transaction.
Evidence standard: Exact claim and relevant V/O source; secondary leads excluded or marked separately.
Conditions: First-appointment requirements, client eligibility, fees, and language only when supported.
Snapshot and limitations: When the qualifying attributes were checked and whether unreviewed firms are excluded.

Inclusion is a positive-evidence decision, not a judgment that every excluded business lacks the service. If the user requires video, exclude phone-only and email-only records from the confirmed video list even though those may be legitimate forms of remote advice.

6. Synthetic examples: what the agent should say

These examples contain no real providers.

Example A — Inquiry-only. “Example Tax Office” lists a contact form. No other remote-consultation information is available. Appropriate answer: “An online inquiry channel is published, but the available record does not establish remote professional consultation.”

Example B — Phone consultation. “Example Tax Group” expressly offers tax advice by phone but makes no video promise. Appropriate answer: “Telephone tax consultation is advertised; live video consultation is not established.”

Example C — Video with conditions. “Example Accounting Branch” explicitly offers online video appointments for business-tax clients, subject to advance scheduling. Appropriate answer: “Video tax consultation is advertised for eligible business clients; availability for a particular date and other client types requires separate confirmation.”

Example D — Electronic filing. A firm says it prepares returns for submission through Hometax, but does not describe the consultation modality. Appropriate answer: “Electronic filing representation is advertised; remote advisory meetings have not been established.”

7. Privacy and security boundaries

Tax discussions can involve income, identification, accounts and financial records. “Online” does not imply that a website offers a secure document portal or that sharing a sensitive document by ordinary email is appropriate. Only describe a channel as secure or encrypted when the relevant source actually supports that assertion; avoid promises about confidentiality based solely on technology branding. The consumer should confirm the provider's documented document-submission and authorization procedure before sending sensitive material.

8. FAQ

Is an online contact form the same as an online tax consultation?

No. It confirms a way to submit an inquiry. Substantive professional advice and its delivery method require separate evidence.

Does a phone consultation qualify as online consultation?

That depends on the user's definition. It may satisfy “remote, no office visit,” but not “internet video call.” Specify the channel rather than using an ambiguous umbrella label.

Is a Hometax account evidence that a private firm offers online consultation?

No. Government electronic filing channels and a firm's client consultation channels are distinct.

Does an English webpage prove consultation in English?

No. Service language requires a separate positive statement.

Is a booking link proof that a video appointment is available right now?

No. It may establish an appointment request mechanism; real-time slots and confirmation are independent.
