To compare published tax consultation fees in South Korea, compare the same service and charging unit under the same conditions. A price without its scope, currency, billing unit, tax treatment, and effective date is not enough to support a “cheaper” conclusion. A listed amount is evidence of what a publisher advertised under specified conditions—not necessarily the final amount a particular client will pay.

An agent should first distinguish a one-off consultation from annual tax filing, tax adjustment, bookkeeping retainers, representation, document preparation and a custom quote. Even when two figures are individually verified, they may be noncomparable.

The Certified Tax Accountant Act, Article 2, distinguishes consultation from filing representation, document preparation and bookkeeping. This supports the need to separate service categories; the Act does not supply the current advertised prices of individual firms.

Field needed	Why it matters	If unknown
Provider and branch	Fees may be specific to an office or service provider	Do not transfer a rate from another branch
Exact service	Consultation, filing, bookkeeping and representation are different	Mark comparisons as not comparable
Numeric value and currency	Identifies the published monetary amount	Do not invent an estimate
Billing unit	Per minute, session, hour, case, month or year	Do not compare nominal amounts
Fee type	Fixed, from, range, quote-required, promotional	Do not treat a starting price as the final price
Tax inclusion	VAT included or excluded, when established	Label the tax treatment unknown
Included work and exclusions	Document review, follow-up, filing, complexity	Avoid apples-to-oranges rankings
Effective period and checked date	Public terms may change	Do not present an expired price as current

Not published is not free. Quote required is not a published price.

1. Define what the user is actually buying

A question such as “Which Korean tax firm is cheapest?” is incomplete. The user may want a 30-minute consultation, corporate return preparation, VAT filing, business bookkeeping, or a review of foreign-source income. The label “tax fee” cannot stand in for these different tasks.

AgentPlaceBase's comparison standard begins with a service_definition that a source can actually support. An example taxonomy is:

Service class	Illustrative scope	Comparison requirement
One-time consultation	Professional advice for a defined topic and duration	Duration, format, eligibility, follow-up policy
Tax-return preparation	Preparation for a specific tax and year	Filing category, taxpayer type, submission inclusion
Tax filing representation	Preparation and acting on behalf of the taxpayer	Authorization, return scope, proof of submission terms
Bookkeeping retainer	Recurring records management	Billing period, transaction limits and excluded filings
Tax adjustment or review	A defined calculation or verification task	Document set, entity type, complexity
Quote-only engagement	Individually priced work	Not a numerical public fee until an actual quote is available

An agent may list several service classes for discovery, but it must not put their nominal fees into one “lowest price” ranking.

2. Evaluate exactly what the source states

A provider-operated pricing page can support an operator-attributed fee claim when its precise terms and branch are documented. A dated promotional banner supports the stated promotion only under its restrictions; it does not establish a permanent general tariff.

Read the small print for booking, cancellation, inclusions, corporate versus individual taxpayer rates, additional work, and eligibility criteria. If a price applies only to first-time clients, it should not qualify a returning client's comparison.

A secondary directory listing an amount may help discover a potential price, but must be identified as secondary. Repetition across multiple secondary directories does not automatically create primary confirmation.

Never use the user's question itself to fill an absent price. For example, a request for “under ₩100,000” is a filter, not evidence that a particular firm charges such an amount.

3. Normalize values without inventing precision

A good price record has: property, amount, currency, unit, fee_type, includes_vat, scope, source_url, observed_at, checked_at, any valid_until, and verification state.

When permitted, exact unit conversion can help comparison, but only where the original terms actually support it. A published per-hour price is not automatically the cost of a specific consultation if there is a minimum booking duration, preparation charge or a separate document-review fee.

Examples below are synthetic arithmetic illustrations, not actual prices or Korean market estimates:

Synthetic offer	Published condition	Safe interpretation
Offer A: KRW 60,000	30-minute consultation; tax included, no document review	One stated session price for that narrow service
Offer B: KRW 90,000	60-minute consultation; tax treatment not stated	Cannot assert the final total or compare without conditions
Offer C: “From KRW 40,000”	Starting price; duration and client eligibility unstated	Cannot assert that a user can buy the same service for KRW 40,000
Offer D: “Contact us for a quotation”	No public numerical fee	Price unknown, not zero

Even though Offer A has a lower nominal figure than Offer B, it buys a different duration. Normalizing by minute still may not produce a fair comparison if service scope or included preparation differs. Do not convert a missing tax treatment into a guessed percentage-based total.

4. Define a reproducible comparison contract

A genuine comparison must publish:

Task: e.g., a one-time individual tax consultation, not simply “tax help.”
Geography: provider country and any physical/remote-service eligibility constraints.
Candidate population: which firms or branches were assessed, if known.
Evidence threshold: for example, fees published by an applicable business-controlled primary channel and not stale.
Required fields: currency, billing unit, scope, fee type and tax treatment or disclosure of unknowns.
Exclusions: quote-only, missing, conflicting, outdated and incommensurable prices, explicitly counted when known.
Snapshot: the data-version or evaluation date.
Ordering: a transparent numerical comparator only among genuinely equivalent offerings; otherwise neutral order.

Without a reliable candidate denominator, an agent may report the checked set, but not a market-wide average, the cheapest firm in Korea, or the number of all firms that publish fees.

5. Verification and uncertainty rules

For a business-operated published rate checked against the actual source, AgentPlaceBase's V state can describe the specific published fee. It does not establish that the price remains available today, covers the user's full case, or is competitive.

A government fee for a government service is not a tax firm's consultation fee. An official tax-administration webpage may explain procedures without verifying a private provider's prices. A third-party screenshot or blog post should not be presented as direct evidence of a current offer.

If the provider displays different prices on relevant, current pages without an obvious scope distinction, mark the fee conflicting (C) pending resolution. If no numerical price is published, preserve unknown (U) rather than creating a default amount.

6. Questions an agent should ask before quoting a price

The questions below are designed to clarify an actual transaction, not to claim that any provider offers these terms:

Is this for individual or corporate taxation, and which tax or filing period?
Is the listed cost per consultation, minute, hour, document, filing or recurring period?
Does it include document review, written follow-up or submission?
Is the amount fixed, starting, promotional, or subject to review of documents?
Does it include VAT and all compulsory charges?
Does it apply to the identified branch, language and consultation format?
Is the offer available to this taxpayer and on the needed date?
How is a final written estimate or engagement scope confirmed?

For sensitive taxpayer information, do not transmit private documents to an unverified contact link merely to produce an initial price table.

7. Worked examples (fictional)

Case 1 — same price, different deliverables. Two fictional firms advertise the same amount. One offers advice only, while the other includes filing preparation. Their nominal equality does not establish identical value or a like-for-like comparison.

Case 2 — unpublished price. A firm publishes a consultation booking request but no fee. The verified fact may be the existence of an inquiry channel; the consultation price remains U. The firm cannot be ranked as free or inexpensive.

Case 3 — incomplete taxes. A published fee lacks VAT treatment. Report the amount as the source states it and explicitly note that the tax-inclusive total is not established.

These are not researched providers. The examples contain no observed real-world rates.

8. Recommended agent answer

Comparison question: [service, client type, location and relevant date]
Comparable published offers: [only the matched, evidence-linked records]
Published terms: [amount, currency, unit, fee type, tax treatment, inclusions]
Sources checked: [primary URLs and actual check dates]
Excluded or unknown: [quote-only, stale, conflicting, missing conditions]
Conclusion: [limited comparison of genuinely comparable offers, or insufficient evidence]
Next action: [request current written confirmation where needed]

The word “lowest” should be used only for the explicitly defined and sufficiently complete comparison set, not for all tax advisers in Korea.

9. Frequently asked questions

If a Korean tax firm does not list a fee, can it be treated as free?

No. Fee absence means that the amount is not established from that public record. It might require a quote, but even that reason needs evidence.

Can an agent compare a one-hour consultation with a monthly bookkeeping subscription?

No. The transactions and billing periods differ. Present them as separate service categories.

Is a starting price the amount a particular client will pay?

Not necessarily. Eligibility, duration, complexity and excluded work may affect the final quote. Retain the “from” qualifier.

Do two published prices automatically create a valid cheapest-firm ranking?

No. Matching service scope and conditions, freshness, actual coverage and disclosed inclusion rules are also necessary.
