The Honest Take on South Dakota

What It Does Best

The gold standard. Best combination of perpetual duration, no state income tax, and strongest asset protection. Trust companies here know what they're doing.

The Downside

It's popular, which means trust companies can be picky. Minimum fees run $15-25K/year. If you're bringing less than $3M, expect to feel like a small fish.

Use SD If...

  • ✓You want the safest, most battle-tested option
  • ✓Your trust is $5M+ and you want premium service
  • ✓Asset protection is a real priority (not just theoretical)

Skip SD If...

  • ✗Your trust is under $2M (fees will eat your returns)
  • ✗You have a specific Nevada or Delaware attorney relationship
  • ✗You need a trust company that's more flexible on minimums

Bottom Line

For 80% of people reading this, South Dakota is the answer. The only reason to look elsewhere is if you have specific needs that SD doesn't serve, or if fees are a dealbreaker.
