I have a spouse visa and a full salary in Japan. I did some freelance writing for a foreign company in 2023, where the funds were directly deposited into my Japanese bank account. My freelance earnings were less than 200,000 yen.
I thought the procedure was to report my earnings via a kakutei shinkoku after my company does nenmatsu chosei. However, I never registered a kojin jigyo for my freelance work. I asked my wife and she said it wasn’t necessary to apply for one with such little earnings on the freelance side. But now I am worried that I should’ve applied for one as I’m not sure how my freelance income should be taxed.
Do I just bring the invoices of the freelance writing gigs to the tax office and fill out a kakutei shinkoku there? Or should I file for a kojin jigyo and retroactively apply the freelance work to that (is that allowed)? I just want to make sure I accurately report all income from 2023 in case I need to pay additional taxes.
