The research picture here is nuanced: yes, some wealthy individuals and companies do relocate when taxes rise, but the scale is consistently smaller than feared, and the revenue from those who stay usually outweighs the losses. Here's what the data and examples actually show.
| Factor | Evidence |
|---|---|
| Millionaire migration rate | 2.4% annually (lower than general public) [1] |
| Tax-motivated moves (share of all moves) | ~2% of departures [3] |
| CA billionaires who left before 2026 wealth tax | 6 out of 214 (3%) [5] |
| Revenue from stayers vs. leavers | Stayers' revenue exceeds losses from exits [2] |
| Florida's pull | Millionaires 3x more likely to move to Florida than leave it [4] |
The pattern is clear: relocation does happen, and when a high-profile billionaire leaves, the tax loss can be enormous due to the concentration of wealth at the top. But the broader flight is far more limited than political rhetoric suggests — wealthy people's lives, businesses, and networks are deeply rooted in place, making radical relocation costly even when taxes rise.[3][2]
