Founder and owner of MTS Professional Tax Service — the trusted advisor Silicon Valley families recommend to their families and friends.

Moises Salas III
Founder & Owner · San Jose, CA
Moises founded MTS Professional Tax Service on a simple belief: successful people deserve a tax advisor who is as thoughtful about their financial future as they are about their business.
For over three decades, he has served Silicon Valley individuals and businesses from every walk of life — technology founders and family restaurants, real estate investors and W‑2 professionals, first-time filers and second-generation family enterprises. Every return receives the same personal attention.
Along the way he has built a practice known for four things: honesty, patience, thoroughness, and the kind of long-term thinking that saves clients real money. Many of the families MTS serves today were introduced by clients Moises met twenty years ago.
"My greatest measure of success isn't a return I filed. It's the client who calls me before making a decision — and the one who sends their kids to me twenty years later."
MTS remains a boutique practice, on purpose. Moises takes on a limited number of new clients each year so the work stays personal, the strategy stays sharp, and the relationships last as long as clients want them to.
Three decades preparing individual, corporate, partnership, estate, and trust returns.
Personally reviews every return. Nothing outsourced, nothing rushed.
Deep expertise in the situations Valley clients actually face — equity, RSUs, exits, real estate.
The advisor clients call before a big decision — not just at filing time.
Individual, S-corp, C-corp, partnership, estate & trust — under one roof.
Secure, efficient federal and state filings across all 50 states.
