"The Taxes Will Eat Me Alive" — The Fear vs. The Actual Bill

Part 4 of 5 in the Why Sellers Wait series. Pairs with the one-page flowchart of the same name.

If you bought your Marin or Sonoma home decades ago, you're sitting on two things: a lot of appreciation, and a lot of tax fear.

The fear usually sounds like this: "Our gain blows past the exclusion. And if we sell, we lose our Prop 13 tax basis forever. The taxes will eat us alive." So the tax fear makes the decision by default — often based on numbers no one has actually run, or rules that changed years ago.

Let's walk the same path the flowchart does. (And the disclaimer that matters: I'm not a CPA, and this isn't tax advice. My job is to get your real numbers on paper with your tax professional — never to replace them.)

First question: are you (or your spouse) 55 or older?

Because if so, Proposition 19 may be the biggest thing you don't know about. Since 2021, qualifying California homeowners 55+ (along with certain other owners) may transfer their low property-tax basis to a replacement home anywhere in California — up to three times. The "we'll lose our Prop 13 basis forever" fear is, for many sellers, simply out of date. We verify eligibility with the county assessor and your CPA before you decide anything.

Second question: is your gain actually above the exclusion?

The federal capital-gains exclusion on a primary residence — up to $250,000 single, $500,000 married filing jointly — still applies. For plenty of sellers, the exclusion covers more of the gain than they assumed, and the tax story ends there.

If it doesn't: raise the basis

Here's where documented history pays off. Your taxable gain isn't sale price minus purchase price — it's sale price minus your cost basis, and capital improvements over the years raise that basis. The kitchen in 2004. The roof in 2015. The addition, the systems, the landscaping infrastructure. We inventory every documented improvement, and the taxable gain shrinks accordingly.

And if a meaningful gain still remains?

Then it's a strategy conversation with your CPA — timing, installment structures, or other options your tax professional recommends. You might still owe something. But you'll decide with a real number in front of you, next to a real net-proceeds sheet, instead of a guess that's been keeping you up at night.

In my experience, the fear is almost always bigger than the bill. Not always — but you deserve to know which one you're dealing with.
