#1 There's no BEST OFFSHORE Jurisdiction for you because it depends on your tax residency, citizenship, monthly turnover, banks' jurisdictions, brokers' jurisdictions and your business goals.
You want a jurisdiction that provides strong privacy? Nevis
You want a transactional bank account for your Nevis company with top tier 1 banks in USA or UK? Forget it, UNLESS you come with MINIMUM 1 Million USD, BUT you BETTER 5 Million EVERY MONTH.
You want an Investment Business Account (Wealth Management) for your Nevis company with top tier 1 banks in USA or UK? Yes very possible. At Least 1 Million MONTHLY.
Here at offshore jurisdictions AND︀ Transactional High Street Banks we play big.
Now let's talk about the broker's jurisdictions...
You want a solid broker? Saxo bank BUT... you may need to speak many times with︁ the most importante people there to make it work for your Nevis company because... they︂ don't like Offshore, unless you're smart and going to help them make money. Now Swear︃ your nevis is not going to be blacklisted by EU because you saxo broker is︄ licensed in EU, if it happens, you better say Good bye to your trading account...︅ because that jurisdiction is blacklisted.
We don't know what may happen at future.
Now let's︆ talk about your business plans?
What do you want to do with your millions? Store︇ them like a pension plan? Invest them in Real Estate like Annaly?
BUY GOLD and︈ hold for years? BUY Crypto and hold for years? Buy stocks and hold for years?︉
You need to structure it very well because for these options there are many interestings︊ plans.
My input for you is:
1. Research and THEN ask, How to reduce Tax︋ burden for ABCD TAX resident ? How to optimise Tax Obligation for ABCD tax residents?︌
2. Research your LOCAL LAW and read WHAT THEY TAX, HOW THEY TAX and then︍ try to figure out things that is not within the LAW.
After you have basic︎ info for number 1 and 2, then
3. Research the most used jurisdictions according to️ the answers provided for number 1 and 2 and what's their relationship with offshore and onshore.
4. Have a good plan as I wrote at the beggining and finally
5. Make a consultation with Local Tax Lawyer and International Tax Lawyer in YOUR Industry for your TAX residency and FOR your Goals.
There are many information you have not provided so don't expect here amazing answers.
All the best.
