Best country for this family?

I agree. The OP talked about an annual income of $60-90,000 and three children (so three dependents on his 1040 form). His effective tax rate is not going to be very high. What I thought was weird is that he mentioned that his “finances are strong”, but based on those numbers, his family is safely in the middle class. Not at all “well-to-do”.

Speaking of costs, another plus might be office rent since the OP has a business. I read recently that Wellington had the second-cheapest office rent among major cities in the Asia-Pacific. (Manila is cheapest and Bangkok No. 3.) Why is Wellington so cheap? My guess is because it’s so far away from other major markets. Australia is what? 1000 miles away?

Here’s the report.
