If you're an adult you already have an ID card...I'm talking about renewing one, not applying for the first time. One applies for one in person when one turns 18 (with a birth certificate, a passport if a citizen of another country, or a piece of paper from the border guards if a refugee etc).
Also one needs an ID card plus 2FA authentication(usually connected to a bank account, a physical smart card, or mobile phone) to login to the government services portal in the first place. This portal is seen as a huge accomplishment (in comparison to the inconvenience of having to do every little thing in person, queue for hours etc). It is not just taxes, it is health service, local councils, national(and health) insurance, building permits, basically almost everything one can do in person can be done via this portal - except renew an ID card since the stupid EU rule came in force...
