What the leaked IRS data showed.
ProPublica reported in June 2021, from IRS data it obtained, that Thiel used “stock deals unavailable to most people” to turn a Roth IRA worth less than $2,000 in 1999 into $5 billion by the end of 2019. If he waits to withdraw until April 2027, he will owe no tax on it. Thiel did not comment. [1]
Roth accounts were meant for ordinary savers; the rules then did not stop founders putting cheap startup shares inside them. The Senate Finance Committee held a hearing on such accounts. [2]
What we can’t tell you. The tax returns are not public. Thiel has not confirmed the figures.

Did he leave to avoid a billionaire tax?
In December 2025 Thiel Capital opened an office in Miami, as a proposed one-time California tax on billionaires was being debated. BBC Mundo says he moved his own residence to Miami at the end of 2025, “fleeing” the proposed tax. [1][4]
In February 2026 Palantir, where he is chairman, moved its headquarters from Denver to Miami. [2][3]
The timing fits, and the BBC states it as the reason. He has not said so himself in anything we found.
What we can’t tell you. Residency for tax purposes is a legal question we cannot check.

The Guardian, following the Wall Street Journal, said he does not plan to live there. The Times lists homes in Hawaii, New Zealand, Miami, Washington and Buenos Aires. [1][2]
