In 2023 I changed jobs twice, and have the 源泉徴収票 of the three companies (from January to April for the first company, from May to November for the second and December for the current). I also did 年末調整 (with no dependants) and in this month’s payslip I’ve been returned a little quantity.
My doubt is that before entering actual company during October I did some side work for them, made an invoice and was payed for a little over 26万円. Do I need to do a 確定申告 regarding this amount only? How much taxes should I expect to pay over that quantity and would those taxes be payed when I do the 確定申告？Sorry for the inexpertise.
