From my standpoint, it is hard to see the benefit for that "little" sum of money that you mentioned, $60 000 per year.
With an offshore company or similar setup, it will easily cost you around $2000 in fixed fees per year. Add in the double for banking fees, filing costs, accountant and similar things. Then add maybe another $1000 for own costs, extra costs, for this in your own country. Say the setup costs you $5000 per year. That is 12% of the total, what is your current tax rate?
