This is a special case. I mean the case when a person does not fall under the criteria of a tax resident in any country of the world, this will not create problems in the future?
This will create problems if your country of residence is a country that's agressive to claim tax, such as in EU.
Each country has different laws and enforces those more agressively than others.
What is key is :
1) you are not registered anymore in your country of citizenship, this means your address in the register will indicate your address of residence in the other country, also on your ID. If you apply for a new passport you will also do that in the country of residence through the embassy or consulate (that often requires proof of residence by registration proof and residende permit / long term visa)
2) you have no more family ties and assets nor any bank account or any income from your in your country of citizenship. This is not a clear requirement but any asset or income will give tax authorities the opportunity to prove your ties with your home country and consider it your permanent address (since the other periods you are just travelling)
3) you should be able to provide the proof you lived abroad by providing : rental contracts, spending in supermarket (by your local credit card, definitely not by a credit card from your country of citizenship), gym, etc.. A tax
certificate also could be asked.
Every situation and risk assessment is different, nevertheless if you want to be safe, make sure ALL ties are cut with country of residence, get a residence in a low tax country that doesn't tax foreign income and change your residence in your citizenship country to that location. Rent a (cheap) place there and spend some time there (so at least you can show you entered once a year) and most time travel around as a nomad.
You need to have a residence and have a permanent address somewhere and if you don't have then it's assumed your permanent address is in your country of citizenship. Even you are not there or less than 183 days, they still can come after you and tax you.
