I Just Hit $1M: Your 90-Day New Millionaire Checklist
Crossing $1M in investable assets is a genuine inflection point — not because of the number itself, but because the optimal financial playbook actually changes at this level. Below $1M, low-cost index funds and maxing your 401(k) captures most of the available value. Above $1M, complexity increases faster than your balance: asset location starts costing real money, tax-loss harvesting mechanics shift, your insurance exposure grows, and your estate plan goes from "nice to have" to "your heirs will curse you if you skip it."
This checklist is organized into 90 days. The ordering matters: protecting what you have comes before optimizing it; optimization comes before building complexity. Work through it in order if you're starting fresh, or use it as a gap audit if you've been at this level for a while.
Days 1–30 Lock Down the Basics
Before you optimize anything, make sure the foundation is solid. These are the moves that prevent catastrophic loss of what you've built.
Days 30–60 Optimize Your Tax Picture
The biggest dollar-value moves available to $1M investors are tax moves, not investment-selection moves. These are the ones with real numbers attached.
Days 60–90 Build the Long-Term Plan
With protection and core tax moves in place, these are the longer-horizon decisions that separate well-managed wealth from wealth that erodes over decades.
