Discussion regarding my curent setup

Welcome aboard. It's always good to keep your money in as many different bank accounts as possible in your situation. However, in regards to the tax issue you may or may not face some time in the future I would get an certified accountant to help keep track on all your income on a annual basis. He may also be able to help you with a letter that confirms you don't have to pay tax anywhere because of your situation.

With these you shouldn't enter into any troubles with a EU bank.

can share the emi that you use?

Makes me wonder how long will Mistertango tolerate something like this :D

It's very interesting... What is the field of business (more specific than "crypto sector")?
I'd say the banks will not really want to ask you whether you paid taxes, though your home country may if you didn't cut ties with it.

The banks may ask for some documentation for incoming and outgoing transfers, both corporate and personal - which means to provide invoices, agreements, maybe even screenshots of other accounts etc.

They probably won't ask you to prove that you paid taxes as there is no reason or benefit for them to ask that.
If they will suspect you of money laundering or shady business, they'll just close the account and tell you to transfer the money to another account in your name which may be a problem if you are using darks.

I prepeared all invoices as I go for Mister Tango. I have passed their verification also for business account, the same I did with Revolut by using real darks with my own picture on.

MT asked me already for invoices and account balance sheet, I provided both to them and they didn't ask for more. I already read about the horror stories in the public forum about MT but must say, if you get organized, you won't have troubles.

A comment about tax. I think it's better to pay a little tax somewhere than no tax at all. No tax at all will soon or later give problem in my opinion. Particularly in a world where the options are more and more reducing to escape. For example let's say in 10 years you want to come back to the country where you born, even if now you think you will never. Then they ask you more about your taxes all those years outside. I think if you show a proof with small taxes somewhere, they will swallow it. If you show a paper which prove you didn't need to pay tax during 10 years, it's more hard to swallow. If you have no paper at all, even worst...

There are so many stories of old businessmen with good success in their life and at end they lost everything with tax because they couldn't prove the past... And the funny thing is they paid accountants all their life to manage that.
When the tax payer is on you, better to tell him a story he can swallow. Telling him you legally paid no tax, especially if you look obviously rich, just give him anger to dig more about your case. And he will until he find something!

I agree with you @kevino if you want to live a normal live where you don't have to look back each second to see if someone comes after you then you want to pay a minimum of tax in an attempt to avoid it.

There are multiple ways to reduce your tax and to even exploit local and foreign company setups for maximum "private" spendings if your have sufficient of money and do it right.

On the other hand, if you only make a small amount of profits each year say less than 100K euro it's going to be a question about if it's worth to setup something offshore or better to speak with a local tax advisor.
