In Japan, you can lodge tax online (etax).
However to do so, you will need IC Card Reader so your PC can recognise the My Number Card.
You can also access to etax using ID and Password however this is “temporary solution” for those who don’t have IC Card Reader.
Also, if you’d want to register for My Number Point (MyNaPoint, マイナポイント), you will need IC Card Reader.
IC Card Reader I got
Will be total waste to spend bucks for something which you only use once or twice an year.
I went to amazon.co.jp and purchased the most cheapest and reliable (My Number Card Compatible) IC Card Reader.
Costed me like 1200 ~ 1300 yen.
CD contains driver software for Mac.
No driver needed for Windows and it will be automatically recognised once plugged.
The card stays in the slot pretty firmly.
When you insert the card, the IC logo bit lights up and you’ll hear the sound like when you plug in the usb.
