One of the themes we cover on this blog is the importance of place in a world where people are becoming increasingly untethered. While I'm a firm believer that great local places have enduring value, this does not mean that technology isn't driving greater fluidity in the way people live, work, play, and optimize their taxes.
Over the last decade, the population of ultra-wealthy Americans (those with a net worth greater than or equal to $30 million) has risen noticeably in two states: Texas and Florida. California, a high-tax state, still dominates; however, Texas has overtaken New York, and Florida has overtaken Illinois. Notably, both Texas and Florida have no state income tax — they also have warmer weather than New York and Illinois.

As we have talked about before, there's a longstanding migration trend in the US toward sun, urban sprawl, and lower taxes. But it's not always as clear-cut as a rich person fully relocating to a lower-tax jurisdiction and completely severing ties. The enduring value of place means that many people still travel back and forth to meet whatever personal or professional obligations they might have.
And today, there are apps, such as TaxBird, that will meticulously track the number of days you spend (or your phone spends) in each jurisdiction to ensure you don't cross any important residency thresholds.
The global standard is the 183-day rule (or roughly half a year). In many or most cases, if you are physically present in a place for more than 50% of the year, you are automatically considered a resident for tax purposes. But it's not always this simple, so check with your tax advisor. Regardless, the untethering of life and work is surely allowing more people to tax-optimize in this way.
None of this is surprising.
As Charlie Munger used to say, "Show me the incentive, and I'll show you the outcome." But now we need to think about the longer-term ramifications for colder, higher-tax jurisdictions as capital and tax revenue continue to be siphoned off, not only to Texas and Florida, but to Dubai, Singapore, Hong Kong, Switzerland, Monaco and other places.
