Step-up in basis after a death in San Francisco — high values make documentation consequential.

Get guidance

Overview

In San Francisco, basis mistakes are rarely small. Families search this topic because a future sale can turn on records created now. Learn what step-up generally means, which documents help, and why an appraisal supports the tax conversation — then confirm details with a CPA rather than a blog post.

What to keep in mind

  • Higher prices amplify the cost of weak basis documentation
  • Ownership details can change the analysis — bring them to your CPA
  • Pair tax advice with a formal date-of-death valuation when real estate is involved
