Leave Before You Buy

The last post ended on a question: are you going to be a California taxpayer for the next sixteen years? Because that's roughly how long it takes to collect the state portion of a cost segregation study after California strips out the bonus.

For a lot of the people reading this series, the honest answer is no. They're three years from retirement, or the company went remote, or they've already been running the numbers on Nevada. And once that's the answer, the whole thing reorders itself.

Buy first, leave later — the version that costs you

Say you buy the short-term rental while you're still a California resident. You add back the bonus depreciation on your state return, exactly as the last post described, and you start collecting the California portion in slow annual installments. Year one, year two, year three.

Then you move to Nevada.

California taxes residents on all of their income, wherever it comes from. It taxes nonresidents only on California-source income — and a short-term rental in Tennessee or Arizona isn't California-source. So the moment you stop being a resident, the remaining state deductions have nowhere to land. There's no California return for them to reduce.

You ate the add-back. You never collected the recovery. That's the one version of this where the state money is genuinely gone rather than deferred.

Buy after you go and the problem never exists. Same property, same federal deduction, no add-back, no thirteen-year tail you're going to walk away from.

Don't move for the deduction

Now the correction, because I don't want anyone rearranging their life over the wrong number.

The federal 100% bonus depreciation is yours no matter where you live. That's the large figure — the one worth tens of thousands in the first year. Residency doesn't touch it.

What residency actually changes is the tax on your wages, your equity compensation, your business income, at rates topping out at 13.3%. For the high earners this series is written for, that's the real money by an enormous margin. The depreciation tail is a footnote next to it.

So nobody should relocate to rescue two thousand dollars a year in state deductions. If you're leaving California, leave for the reasons that are actually worth leaving over. The depreciation sequencing is something you get right while you're doing it — not a reason to do it.

What leaving doesn't fix

Here's the part people get wrong in the other direction.

Moving does not un-California your existing California property. If you're funding the purchase by selling a Ventura County rental, that gain is California-source and stays California's no matter what address is on your return when you file. Same if you exchange out of state — the deferred California gain follows the replacement property, and the annual reporting obligation follows you with it. I've written that up in detail in the Moving California Equity series: The Clawback Nobody Mentions.

The same logic applies to the rental itself. Buy the short-term rental in California and it's California-source forever — you'll be filing a nonresident California return on that property long after you've stopped filing a resident one.

So the order of operations is: the tax on the California asset is fixed and already priced. Changing residency only protects what comes after.

There is no day count

One warning before anyone starts booking movers.

California has no bright-line residency test — no magic number of days that makes you a nonresident. It's domicile plus a facts-and-circumstances look at where your closest connections are: where your family lives, where your professional licenses sit, where your doctors and your bank and your cars are registered, where you actually spend your time. The Franchise Tax Board publishes its framework in Publication 1031, and it audits departing residents seriously — particularly departures that happen to coincide with a large income event.

Which is exactly what a cost segregation year looks like. Leaving California in the same tax year you generate a six-figure deduction is a fact pattern that gets attention. That's not a reason not to do it. It's a reason to do it with someone who handles residency work, with the file built as you go rather than reconstructed under audit two years later.

The whole thing in one line

If you're staying, buy and take the slow California recovery — it's real, it just takes sixteen years.

If you're leaving, go first and buy second.

If you're not sure, that uncertainty is itself the answer to a question worth sitting down over, because the cost of getting the sequence backwards is larger than anything else on the page.

I'm a broker, not a CPA and not a residency attorney. This is the shape of the problem, not advice on your situation. If you're weighing a move and a purchase in the same window, get both professionals in the room before either one closes — and if you want help thinking through what to do with the California property in the middle of it, that's the conversation I have every week.
