About Theo Marsh
Theo Marsh is a tax and residency advisor with Coastline Tax Counsel, advising families and executives establishing Florida residency. Theo focuses on domicile, day-count and the sequencing that makes a residency position defensible.
Clients relocating from high-tax states or across borders often underestimate how property timing, documentation and advisor coordination affect the outcome. Theo works to a plan rather than reacting after the move.
Through the relo network, Theo coordinates with property, immigration and schools specialists so tax planning sits inside the full relocation, not a separate track.
How Theo helps
- Plans domicile and residency properly, not late.
