ExploreAbout this exam
The Korea Certified Tax Accountant (CTA), known in Korean as 세무사, is a Korean professional licence for tax practitioners. Holders prepare and file tax returns, represent clients before the tax authorities, and advise on income tax, corporate tax, value added tax, inheritance and gift tax, local taxes, and cross-border issues. Many work in accounting firms, in-house tax departments, law firms, or independent practice. The examination is administered in Korean and tests both technical knowledge and the practical ability to compute tax and draft returns. It is structured around seven domains: Tax Law I (National Tax Basic Act and Income Tax), Tax Law II (Corporate Tax, VAT, and other national taxes), Tax Law III (local taxes and international taxation), Financial and Cost Accounting, Economics, Business Administration and Commercial Law, and Tax Accounting Practice covering bookkeeping and return preparation. The tax law subjects carry the greatest combined weight, followed by accounting, so most candidates build their schedule around those. Preparation typically combines a structured course, systematic reading of the statutes and their enforcement decrees, and heavy repetition of past-style computational problems, with the written component requiring candidates to explain rules and apply them to fact patterns. The official examining body publishes current details on eligibility, exam dates, fees, and scoring; check its site for the figures that apply to your cycle.
What you'll study
About Korea Tax Accountant preparation
What is the exam format?
It combines multiple-choice questions with a subjective written component. The objective papers test recall and computation across tax law, accounting, economics, and commercial law; the written paper requires you to explain rules and apply them to a fact pattern. Confirm the current structure and subject-by-subject arrangement on the official examining body's site.
How difficult is it, realistically?
It is widely regarded as demanding. Volume is the main challenge: several statutes plus accounting, economics, and law, each tested at a level requiring computation rather than recognition. Candidates who pass usually report multiple full study cycles and extensive problem practice rather than a single pass through the material.
Can I retake it if I fail?
Retake rules, including whether partial subject passes carry over to later cycles, are set by the administering body and change from time to time. Do not rely on secondhand accounts. Check the official site for the current rules on subject-based credit retention and re-registration before planning your schedule.
How much time should I plan for?
Most serious candidates plan a year or more, often two, with several hours daily in the final months. The tax law subjects take the longest because they require reading statutes and enforcement decrees closely and then drilling computations. Working candidates typically extend the timeline rather than compress daily hours.
In what order should I study the subjects?
Start with Tax Law I, since income tax concepts reappear in corporate tax and VAT. Add accounting early because it is calculation-heavy and rewards steady practice. Keep economics and commercial law for a later phase, when memorisation is more efficient, and leave integrated return preparation until the tax subjects are solid.
What are the most common failure modes?
Three recur. First, reading statutes without doing computations, so rules are recognised but not applied. Second, neglecting accounting until late, when it cannot be drilled properly. Third, memorising numbers and rates instead of the underlying logic, which collapses under unfamiliar fact patterns. Written answers also fail when candidates state conclusions without showing the calculation.
How should I use past exam-style questions?
Treat them as the core of your practice, not a final check. Work them under time pressure, then review every error against the statute rather than the answer key. Repeating a problem until the reasoning is automatic matters more than covering many problems once, especially for corporate tax and VAT computations.
Do I need to know Korean law in Korean?
Yes. The exam is delivered in Korean and tests Korean statutes, so you must read and write legal Korean comfortably. Translation alone is not enough for the written paper, where precise terminology and clear structure affect scoring. Non-native speakers should budget extra time for reading speed.
What does the credential let me do?
It is the licence for professional tax practice in Korea, covering return preparation, representation before tax authorities, and tax advisory work. Many holders work in accounting firms, corporate tax departments, or independent practice. Confirm the current scope of practice and any registration requirements with the relevant authority.
Where do I find dates, fees, and passing scores?
The official examining body publishes the current schedule, fees, eligibility rules, and scoring standards on its website. These figures change between cycles, so check the site directly for your year rather than relying on forums or older prep material.
