I decided to sell off my Ether holdings to the tune of 180,000 yen in profit.
I guess my question is, do I need to file my taxes now?
Up to this point, my company has usually taken care of them, so I am wondering if this
is a gain that is small enough that I can let my company keep doing it
(as in, maybe there is amount of gains allowed)
or am I on the hook to report myself?
And how would I go about this??

Yeah, I should probably know...but better late than never!

Tax return next year, 雑所得 field (assuming the rule's havn't changed by then). It counts as income, but it's not huge so might not affect you much.

You need to show them the paperwork and how you worked out the figure too. I believe they have a recommended method of calculation, but it's changed since I last looked at it.

Thanks for the information!
I took a look around, it looks like I have 200,000 yen worth of leeway a year for misc. income.
So I am assuming that, since I don't have any income outside of my salary that I can sell up to 200,000 without having to declare.
Which means I assume I can keep letting my company take care of my taxes.

Anyway, here is where I am getting that conclusion from:

Ah, sorry I didn't remember about the allowance. Good to know. And girigiri for you.
