I lived in Texas for many years. Now I live in Colorado but maintain a
residence in Texas. I have established a trust. My financial advisor
recommended that I keep Texas residency due to tax and probate
reasons. I dont know why and I dont get clear answers. If I went ahead
and took Colorado residency it would make my life easier. Car tags,
hunting licensing fees, etc.
Why would I want to keep Texas residency. I feel kind of dishonest
doing it when I only spend 3 or 4 months out of the year there. My
kids are grown and live in Texas. My wife and I live here, in
Colorado. We're in our 70s. Can anyone help me answer this?

Having lived in both Colorado and Texas, I would guess that one reason
is that Colorado has a State Income Tax, whereas Texas doesn't.  Since
probate deals with what happens with your estate after you die, I'm
guessing (and ONLY guessing) that Colorado takes a much larger chunk
out.

Hope this is helpful!
