TOPIK Practice – TOPIK I 어휘 [어휘] 1–5 (2/4/2026) – tax filing deadline

정답: B. 기한

How to solve: The question asks for a word with a similar meaning to '마감일' (deadline). '기한' also means a deadline or a fixed term for an action.

A — '시작일' means 'start date', which is the opposite of a deadline.

B — '기한' means 'deadline' or 'due date', which is a direct synonym for '마감일'.

C — '휴일' means 'holiday', which is irrelevant to a deadline.

D — '발표일' means 'announcement date', which is when something is announced, not its deadline.

정답: C. 세금 신고

How to solve: The question describes the act of informing the government about taxes and submitting related documents. This perfectly matches the definition of '세금 신고' (tax filing).

A — '세금 납부' means 'tax payment', which is paying the tax, not the act of informing and submitting documents.

B — '세금 공제' means 'tax deduction', which is a reduction in taxable income.

C — '세금 신고' means 'tax filing' or 'tax report', which involves declaring income and submitting necessary documents to the tax authorities.

D — '세금 환급' means 'tax refund', which is money returned to the taxpayer.

정답: C. 납부

How to solve: The sentence discusses income tax and a deadline (5월 31일). The most appropriate action to be completed by a deadline for income tax is '납부하다' (to pay).

A — '준비' means 'prepare'. One prepares tax documents, but the sentence refers to the action by the deadline, which is usually submission or payment.

B — '연장' means 'extend'. While extensions are possible, the sentence states 'until May 31st,' implying the normal action by that date, not an extension of it.

C — '납부' means 'pay'. This is the most suitable verb for completing the action of paying income tax by a specified date.

D — '취소' means 'cancel'. This is irrelevant to paying income tax by a deadline.

정답: B. 기한 연장

How to solve: The question asks what it's called when you postpone a deadline ('마감일을 늦추는 것') because it's difficult to pay taxes on time. This is '기한 연장' (deadline extension).

A — '세금 감면' means 'tax reduction', which is about lowering the amount of tax, not changing the deadline.

B — '기한 연장' means 'deadline extension', which perfectly describes postponing the deadline.

C — '서류 보관' means 'document storage', which is about keeping documents, not changing a deadline.

D — '소득 증가' means 'income increase', which is about earning more money, unrelated to extending a deadline.

정답: B. 의무

How to solve: The sentence states that all citizens with income have something regarding tax filing. Filing taxes is a legal requirement, not a right, opportunity, or hope. Therefore, '의무' (obligation/duty) is the most appropriate word.

A — '권리' means 'right'. While taxpayers have rights, filing taxes is generally an obligation.

B — '의무' means 'obligation' or 'duty'. This accurately describes the mandatory nature of tax filing for those with income.

C — '기회' means 'opportunity'. Filing taxes is not an opportunity.

D — '희망' means 'hope'. This is irrelevant to a legal requirement.
