確定申告

• 読み: かくていしんこく
• ローマ字: kakutei shinkoku
• 漢字の分解: 確定 (determination; 確 = certain + 定 = fixed) + 申告 (declaration; 申 = state + 告 = report) → final tax declaration
• 発音: /ka.ku.te.i.ɕiɴ.ko.ku/

意味

Annual tax filing; the process of declaring income and expenses to the tax office, required for freelancers and those with side income.

Every February-March, 確定申告 becomes a trending topic on Japanese social media as freelancers, side-hustlers, and gig workers scramble to file their taxes. For salaried workers whose companies handle withholding (年末調整), it's irrelevant — but for the growing freelance and副業 (side job) economy, it's a dreaded annual ritual. Complaints about confusing paperwork, e-Tax troubles, and tax office queues flood Twitter every year.

例文

1. 確定申告の時期になるとフリーランスの友達が全員病んでる。
2. 今年から副業始めたんだけど、確定申告ってどうやるの？
3. 確定申告ギリギリまで放置してて毎年焦るのほんとやめたい。

避ける言い方
