If your company is tax resident of some jurisdiction with territorial tax system it always leaves a question where the income is sourced and some day you might have to prove it somehow.
This is why Singapore is probably the best jurisdiction for such approach, as it doesn't tax or issue tax residence certificate based on incorporating a company there, so you could get away with the company not being tax resident anywhere, and you can be the company's shareholder and employee/representative. Probably best is︀ not to be the sole director though depending on your exposures.
Its worth noting that︁ Singapore is not a "banana republic" but a reputable financial hub. On top of that︂ its probably one of the best structure for high-risk activities (even arms dealers/defence industry uses︃ it a lot, and they don't have too many great alternative options).
Under Singapore tax︄ law, the tax residency of a company is determined by where the business is controlled︅ and managed, so you could present to Singapore tax officials that board meetings are held︆ in e.g., Bahrain (0% tax country), or in limited cases (Estonia, see below).
However you︇ probably want to have a permanent establishment registered somewhere so you could have some substance︈ for compliance purposes as it would be great to have some fixed place where the︉ company's operations are at least partly performed, and to have a tax number somewhere (and︊ in result better access to banking).
For this purpose I can recommend getting a substance︋ package from Estonia (e.g., rent office and hire one Estonian resident professional director or employee︌ part-time in Estonia). Estonia is a great choice for the following reasons:
1) Estonian legislation︍ doesn't allow claiming foreign companies as tax resident in Estonia. It can only tax its︎ PE.
This means Estonia can only tax the profits attributable to the PE, which can️ as well be 0.
2) even if profits are attributable to the PE, then profits of the PE are not taxed before the profits/assets are taken out from the PE, and not if the assets are returned to the PE in one year
3) you are not obligated to register a branch office, like in many jurisdictions (but can still register for tax and register a PE) and do not need to follow local accounting rules for the PE
4) it helps to access Estonian and other EU financial institutions since you would have established EU presence this way
5) it is even possible to︀ structure it so to have the PE registered, but it will not even be considered︁ a PE under the tax treaty, so the PE is not taxable either.
Depending on︂ your personal tax residence or if you are nomadic it can be a great structure.︃ Happy to help with the setup.
