- Which of those matters depends on what you are optimising for — ending wealth, or tax paid along the way.
- 6 years more paying IRMAA surcharges.
- All of it under the assumptions listed below, which the reader can change.
What the tax change is made of

- Tax on selling the equity position: +$931,202
- Federal income tax: −$63,689
