確定申告

• Reading: かくていしんこく
• Romaji: kakutei shinkoku
• Kanji breakdown: 確定 (determination; 確 = certain + 定 = fixed) + 申告 (declaration; 申 = state + 告 = report) → final tax declaration
• Pronunciation: /ka.ku.te.i.ɕiɴ.ko.ku/

Meaning

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.

Examples

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。 When tax filing season hits, every freelancer I know is falling apart.
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？ I started a side gig this year — how do you even do a tax return?
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。 I put off my tax filing until the last minute every year and panic — I seriously need to stop.

Usage Guide

Context: work, financial planning, social media, freelance

Tone: stressed, dutiful

Do Say

• 確定申告もう終わった？私まだ何もやってない。 (Have you finished your tax filing? I haven't done anything yet.)
• 確定申告はe-Taxでやると楽だよ。 (Filing taxes online with e-Tax is easier.)

Don't Say

• サラリーマンに「確定申告大変だよね」は的外れなことが多い (Saying 'tax filing is tough, right?' to a salaried worker is often off-base since their company handles it)

Common Mistakes

• Confusing 確定申告 with 年末調整 (year-end tax adjustment) — salaried workers do 年末調整 through their employer, while 確定申告 is for freelancers, side income, or special deductions

Origin & History

From 確定 (finalization/determination) + 申告 (declaration/report). The Japanese tax filing system requires individuals with non-withheld income to file between February 16 and March 15 annually.

Cultural Context

Era: Modern tax system from postwar period, trending on social media from 2010s with rise of freelance economy

Generation: Working adults, especially freelancers and side-hustlers

Regional notes: Used across all of Japan. The filing period (February 16 to March 15) is a predictable social media event. e-Tax (electronic filing) has grown but many still visit tax offices.
