There was someone else on this forum who got a legal opinion on this from the Estonian tax authorities. Maybe you can find it through the search function.
You can find more information on the website of the Estonian tax authorities:
https://www.emta.ee/en/private-clie...sidency/determination-residency#counting-days"On determining the place of residence, we proceed from the definition of a place of residence in § 14 of the General Part of the Civil Code Act, according to which the place of residence of a person is the place where he or she permanently or primarily lives."
You can rent an apartment in
Estonia for the whole year, but if you never spend time there, then you don't "permanently or primarily" live there ->
no tax.
You should be able to get this confirmed by the Estonian tax authorities if you send an official inquiry.
Lithuania has similar rules:

You can rent an apartment for the whole year (and registering your residency there) with the intention of using it for sporadic weekend trips to the country only.
You cannot do the same thing in Sweden, as registering your address there would immediately trigger
tax residency.
But please don't just trust me, get this confirmed by a lawyer or ideally directly by the tax authorities in the respective country.
