연말정산 때 iDeCo 공제 칸을 어디에 적는지 드디어 이해했어요. 일본어 서류 부분이 조금 더 자세했으면 좋았을 텐데, 그래도 환급 받는 데 큰 도움이 됐습니다.

年末調整でiDeCoの控除証明書をどう書けばいいか、ようやくスッキリしました。記入例がもう少し欲しかったですが、おかげで還付金が増えて満足です。

Expatriée au Japon depuis trois ans, je n'avais jamais vraiment compris comment fonctionnait le nenmatsu chōsei ni où déclarer mes cotisations iDeCo. Ce cours explique tout étape par étape, avec des captures du formulaire et l'attestation à joindre. J'ai enfin pu remplir la case de déduction correctement et réclamer la totalité de mon avantage fiscal. Le rythme est parfait pour un salarié qui débute, sans jargon inutile. Grâce à ça, mon remboursement a été nettement plus élevé cette année. Je le recommande à tous les employés étrangers qui cotisent.
