Homes overlooking San Francisco Bay in Sausalito, California

Here's the lowdown

  • California voters rejected a one-time 5% billionaire tax, but they made another high-income tax increase permanent.

  • Colorado voters approved a graduated income-tax plan, while several other states raised taxes through legislation this year.

  • The planning problem starts before a law passes because wealth can be illiquid and a real change of residence takes more than a new mailing address.

One loss did not settle the argument

California's billionaire tax lost. The broader push to tax high earners did not.

Proposition 40 would have imposed a one-time 5% tax on certain residents with more than $1 billion in assets. Voters rejected it after a costly campaign centered on whether billionaires would move and take future income-tax revenue with them.

On the same ballot, Californians approved Proposition 3, which made higher income-tax rates permanent. Colorado voters also approved a plan that raises rates on top earners and lowers them for people with less income.

That is the part advisors cannot ignore. A flashy wealth tax can lose while narrower tax increases win.

The map is getting more complicated

California gets most of the attention because it has many billionaires and depends heavily on high earners for revenue. But this is no longer just a California story.

Maine, Hawaii, Rhode Island and Washington passed tax increases through legislation this year, according to the verified source reporting. Future proposals will not all use the same label or tax the same thing. Some may target net worth. Others may raise income, capital-gains or surcharge rates.

Those differences matter. A proposed wealth tax is not an enacted income-tax increase, and neither is the same as a capital-gains surcharge. Advisors need to model the rule that is actually on the table.

A large net worth does not mean a large cash balance

The official California voter guide described Proposition 40 as a one-time 5% charge on covered wealth above $1 billion.

That sounds simple until most of the fortune is stock in one company, a private business, real estate or another hard-to-sell asset.

A founder can be a billionaire on paper without having enough cash to write a tax check. Paying could require selling shares, borrowing or moving money out of another investment. Private assets would also need defensible values even when no daily market price exists.

This is why liquidity planning comes before tax planning turns into a deadline.

Moving is not a form you file

Some wealthy clients will ask whether a lower-tax state solves the problem. Sometimes it can change the math. It does not erase the facts.

States look at where a person actually lives and works. They can examine homes, family ties, business activity, travel, licenses and financial records. Owning a second house or changing an address does not automatically end residency in the old state.

A move also creates non-tax costs. Clients may be leaving a business network, schools, family or a community they value. The tax savings need to be compared with the whole decision, not just one rate.

Planning beats guessing

Nobody knows which state proposal will pass next. That is not a reason to wait for campaign ads.

Advisors can keep asset records current, identify holdings that would be hard to value, model where cash for a tax bill would come from and document the facts behind a client's residence. They can also show clients the difference between an idea, a ballot measure and a law.

California's billionaire tax failed because voters rejected this version. Other states are testing different versions.

The useful preparation is not predicting politics. It is making sure a client has options if the politics suddenly change the bill.
