  • General corporate M&A (real estate transactions and acquisitions of entities that own real estate are in scope)

faq

Common questions

Do I generally start with a Diagnostic?

Yes. The Diagnostic is typically the first step because it organizes the entities, ownership, records, prior years, and upcoming decisions needed for later work, and every Real Estate Tax Office relationship begins with it. For advisory and compliance work, the fit call determines whether it is the right starting point or whether the required background review should be included in that engagement.

How is pricing set?

Prices shown are starting points. After a fit call, we scope the work and set the fee in an engagement letter before anything begins.

How do you handle filing deadlines?

We use a documented extension-first planning process when appropriate. When an extension makes sense, we tell you early and explain why.

Is Bastion & Thorne a CPA firm?

No. Bastion & Thorne is a trade name of Bastion Tax, LLC, which is not a CPA firm and does not provide attest services.

Do you work with clients outside California?

Yes. Holdings in more than one state are often where planning matters most.
