I always file my Japanese taxes directly at the Katsushika city tax office. It’s possible to do it from home online, but honestly it’s so confusing I’d rather just go there and have the staff help me do it at a terminal.
This year, of course, things were different. Instead of long, crowded lines they strictly controlled admissions.
There was the usual confusion about my application since I get paid from my American company in dollars and had a US W-2, but after calling over the expert it worked out in the end, as usual. I always bring the last few years’ filings with me so they can remember what they decided goes where.
Done for another year! Took a taxi there and back…
