This book is a practice book for the first-round exams for certified public accountants and tax accountants, written to help candidates effectively prepare for the exam by reflecting the latest revisions to tax law and past exam questions.

The law passed the National Assembly in December 2024, but its enforcement decree is currently only in the legislative notice stage and has not yet been finalized.
For students who want to use this book to make a final review before the first exam, which is just around the corner, we cannot delay the publication of the book any longer. Therefore, we have published “2025 Multiple-Choice Tax Law 1500 Questions” by reflecting all the contents of the law confirmed at the end of 2024 and the contents of the enforcement ordinance based on the legislative notice in January 2025, and incorporating all the necessary information for the purpose of the exam.
If the enforcement ordinance is finalized around mid-February and differs from the legislative notice, we will immediately publish an errata table.


The features of the 1,500 objective tax questions in 2025 are as follows.

first

“1,500 Objective Tax Law Questions” is comprised primarily of objective questions from past exams on corporate tax, income tax, value-added tax, as well as the National Tax Basic Act, Inheritance Tax and Gift Tax Act, National Tax Collection Act, International Tax Adjustment Act, and Tax Evasion Punishment Act.
In addition, to help you quickly summarize the key contents of each detail, “Final Key Summary Tax Law,” which consists of key contents of each detail and true or false questions, has been published as a separate textbook.

Second

The unit structure of “1500 Objective Tax Law Questions” and “Final Key Summary Tax Law” is identical to ensure that learning outcomes can be accurately checked after the summary of key contents by detail and solving related objective questions.

Third

A table of trend analysis of questions that has been tested in detail on the first-stage exams for certified public accountants and tax accountants over the past 12 years (12 years for corporate tax, income tax, and value-added tax, and 14 years for other tax laws such as the National Tax Basic Act) is included at the beginning of each chapter.

Fourth

The solution and explanation sections are separated to make them invisible when solving a problem and to allow for immediate confirmation after solving the problem.
In addition, in order to allow immediate confirmation of the main revisions in the explanatory section, the revised laws and already revised enforcement ordinances are marked as revisions, and the enforcement ordinance (draft) that has been announced for legislation and will soon be revised is marked as draft enforcement ordinance.

Fifth

All questions are composed of past exam questions.
Although the content could have been included in the first exam, we have modified the questions from the second exam to reflect the first exam format and included them. We have included a total of 1,475 questions from the previous exams so that you can study while checking the frequently asked questions.

Sixth

The problems in each chapter are divided into ① basic problems and ② advanced problems according to difficulty.
For test takers who are short on time, solving only the basic problems will be sufficient to prepare for the first test.

Even though I put a lot of effort into publishing books every year, I always feel like there are many things lacking.
I will work harder and harder every year.

This book was created with the help of many people.
I would like to express my deepest gratitude to my co-author, Certified Public Accountant Lee Byeong-hyeon, as well as Certified Public Accountant Jeon Su-bin and Certified Public Accountant Kim Tae-hoon, who dedicated their lives to proofreading the book, even giving up their holidays.

I would also like to express my sincere gratitude to CEO Jeong-Beom Seo and the editorial director of Value Books Publishing, who worked tirelessly day and night to improve the quality of the textbook.

Lastly, I would like to take this opportunity to tell my precious family, whom I have neglected too much due to the constant all-nighters, and especially to Minseok, a wonderful man who understands and waits for his father even at a young age, that I love him.
