You still need to have a country of tax residence. If you try to claim no tax residence, you will usually be seen to be a tax residence from your country of citizenship or last domicile and may end up with a lot of back-taxes and fines if caught out. At the very least, you need to claim a country for opening a company and bank accounts.
On a very basic level your company will usually find it easier to have a bank account where you do business and personal accounts where you live or spend a lot of time. Beyond that we need a lot more info to provide any decent advice.
I completely understand. I've been a nomad for 6 months myself. If you have no new tax residency, you'll usually find most jurisdictions accept your last or birth domicile as your tax residency. It may be worth looking in to gaining legal residency in a favourable jurisdiction to cover yourself should you ever need it. Panama is a great option if you qualify for the friendly nations visa.Thank for your reply,
i know my situation is strange but the last years i made 3 worlds tours so i never stay more than 3 month in a country so i don't see where should i declare my business.
