Our honest opinion (which is just an opinion)

South Dakota is structurally one of the most tax-favorable states in the country for both working professionals and HNW asset planning. The combination of 0% income tax + 0% corporate tax + uniquely favorable trust law creates a fortress for HNW wealth planning that few states match. Sioux Falls financial services hub provides solid working employment.

The case for South Dakota:

0% state income tax on all income (wages + retirement + investments)
0% corporate income tax + 0% estate tax + 0% inheritance tax
SD Trust law uniquely favorable (Dynasty Trusts, DAPTs, no perpetuities rule)
Sioux Falls financial services hub (credit card industry concentration)
Sanford Health + Avera Health large healthcare employment
Cost of living below national average

The case against:

Property tax 1.17% effective — moderate (substitution for income tax)
Cold winters genuinely difficult — meaningful lifestyle factor
Limited high-comp career mobility outside financial services + Sioux Falls + Rapid City
Sparse population creates limited cultural amenities
Distance from major medical centers + family for many
Sales tax stack 4.5-7.5% — moderate

Honest take: South Dakota is genuinely the most structurally tax-favorable state for HNW asset planning + retirement. Sioux Falls financial services workers + Sanford Health + Avera Health employees benefit. For HNW estate planning, SD Trusts are widely used by non-resident HNW individuals. Many CA/NY/NJ HNW residents establish SD trusts purely for the asset protection + tax structure, even if they don't relocate.
