TOPIK Practice – TOPIK I 어휘 [Vocabulary] 1–5 (2/5/2026) – tax filing deadline

정답: C. 마감일

How to solve: This question asks for a noun that fits the context of 'tax' and 'May 31st', which is typically a deadline. '마감일' means deadline.

A — '기간' means period or duration. While taxes have a period, '5월 31일' is a specific end date, not a period itself.

B — '서류' means document. This does not fit the context of a date.

C — '마감일' means deadline. This is the most appropriate word for 'May 31st' in the context of tax filing.

D — '의무' means obligation or duty. While paying taxes is an obligation, it doesn't fit directly after '세금' before '은 보통 5월 31일입니다' to mean the date.

정답: D. 신고해야

How to solve: The sentence describes what workers must do with their income tax annually. The action of declaring or reporting tax is '신고하다'.

A — '환급하다' means to refund. Workers usually pay tax or file for a refund, but the general action for income tax is filing it.

B — '연장하다' means to extend. This refers to extending a deadline, not the primary action of dealing with income tax.

C — '제출하다' means to submit. While tax documents are submitted, '신고하다' is the more comprehensive and common verb used for filing taxes in general.

D — '신고하다' means to file or declare. This is the correct verb used for filing income tax.

정답: A. 납부

How to solve: The sentence states that a penalty (가산세) is added if something related to tax is done late. This refers to the act of paying the tax.

A — '납부' means payment. Delaying tax payment (세금 납부) incurs a penalty.

B — '기간' means period. While a tax period exists, delaying the 'period' doesn't make sense in this context.

C — '의무' means obligation. Delaying an 'obligation' is grammatically awkward and doesn't directly lead to a penalty in this structure.

D — '연장' means extension. Delaying an 'extension' doesn't fit the sentence's meaning.

정답: C. 연장

How to solve: The sentence indicates difficulty in preparing documents led to an 'application' for something related to the 'tax filing deadline'. This implies an application for an extension.

A — '제출' means submission. One applies for 'submission', but applying for an 'extension of submission' is more natural.

B — '환급' means refund. Applying for a 'refund' due to difficulty in document preparation doesn't logically fit with '기한'.

C — '연장' means extension. Applying for a 'deadline extension' (기한 연장) is a common action when documents are not ready.

D — '납부' means payment. Applying for 'payment' doesn't fit the context of '기한' and 'difficulty in document preparation'.

정답: B. 의무

How to solve: The sentence describes paying taxes as something important for citizens. This refers to their duty or obligation.

A — '서류' means document. Paying taxes is not a document.

B — '의무' means obligation or duty. Paying taxes is a fundamental duty of citizens.

C — '기간' means period. Paying taxes is not a period.

D — '환급' means refund. Paying taxes is the opposite of receiving a refund in this context.
