Every state taxes investors differently. Here is how Missouri treats capital gains at the top rate, the marriage penalty, estate and inheritance tax at death, municipal-bond interest, the §1202 QSBS exclusion, and a harvested loss, a plain reference to the state's tax code.
~$37,000/yr per $1M taxable
What tax-aware portfolio management alone is worth in Missouri about +3.7%/yr modeled: ~6.3%/yr kept after tax against ~2.7%/yr on a concentrated book. Scales with the portfolio.
This is the floor. It counts the portfolio only and leaves the estate, gifting, and residency coordination at zero, where the larger opportunities usually sit. Illustrative and hypothetical, not a track record: a model applied retroactively to ~30 years of proxy-spliced data, no client capital invested.
Missouri levies no state income tax on capital gains; no state death tax; common-law step-up (only half of jointly-held property).
How to think about Missouri
No lens reads high or severe in Missouri. The strongest reading is harvesting leverage, at moderate, so the work here is maintenance rather than repair.
Five lenses turn Missouri's tax environment into a household decision, the same lenses every state is read through, so any two states weigh on identical terms.
Rate pressure
No state tax on gains, every realized gain keeps its full federal-only outcome.
Estate exposure
No state estate or inheritance tax, only the federal estate tax reaches the estate.
Harvesting leverage
Gains are exempt here, yet a capital loss still deducts against income, a rare one-sided value that keeps harvesting worthwhile.
Mobility value
Already a no-income-tax, no-estate-tax state, the destination other households move toward, not from.
Basis coordination
Common-law basis: only the decedent's half steps up at the first death, plan titling so the survivor is not left with low-basis lots.

Basis step-up
Common-law (separate-property) state: at the first spouse's death only the decedent's half of jointly-held property steps up; the survivor keeps carryover basis on their half (IRC 1014(b)(9), 2040(b)).

What careful tax management can change
Tax law is only half the picture. How a portfolio is
built and run, where each holding sits, how losses are used, how gains are timed, decides how
much of Missouri's tax code you actually pay. The figure at the top of this page is what
that difference is worth in Missouri; these are the levers behind it.

Directional, not a precise figure.
Asset location
The bridge between how you invest and how the household is structured, placing the higher-turnover strategy in Roth and Traditional accounts, where its short-term gains escape tax entirely. Coordination itself; quantified for each household in the After-Tax Lab.
Patient trading and lot selection
Holds positions through short-term noise and chooses which lots to sell, turning gains that would be taxed as ordinary income into long-term gains taxed roughly 17 points lower.
Loss harvesting
Realizes losses and applies them against the highest-taxed gains first, capturing a spread a simple buy-and-hold fund never reaches.

Illustrative / hypothetical, not a real track record and not advice. The tax-management impact figure is a hypothetical, after-tax result from the retroactive application of a tax-management model to ~30 years of proxy-spliced market data on a single illustrative path; no client capital was invested, and hypothetical performance does not guarantee future results. Intended for sophisticated investors; it may not be relevant to your situation, and your actual figure depends on your own holdings, basis, and bracket.
