Maintaining permanent resident permit status (P)

[B&H]

Once you are granted a full 5-year permanent P status and obtained the card, the requirement is to not be living outside Finland for more than 2-years. Since that's the case:
- how can you maintain the status if you do have to move or 2years but less than 5
- how to do the same if you have to move for more than 5 years
- Is it something with local address or bank account
- and do you need authorization from migri
- do you have to pay any taxes whilst living abroad

"If there is an acceptable reason for the absence, the Finnish Immigration Service may decide not to revoke the permit. An application to halt the revocation of the permit must be submitted before the period of absence reaches two years." - www.migri.fi

- how to do the same if you have to move for more than 5 years

I think the previous point stands, but there might be a question about are you really permanent resident of Finland if you don't reside here...

- Is it something with local address or bank account

No.

- and do you need authorization from migri

To move abroad? No.

- do you have to pay any taxes whilst living abroad

Yes, but not to Finland. Google 183 day rule.

Talking about 5 years (instead of four) makes me wonder are we talking about the permanent residence for EU citizens or the permanent permit for others.

Irrespective of that, citizenship would be of course for life, if one can manage the language test and there are not other obstacles.
