Why Gentry Tax & Advisory

Depth where commodity firms stop.

01

Cross-border is the specialty, not a sideline

Foreign trusts, PFICs, treaty positions, Form 5472, exit tax — the hard parts of international tax are our core competencies, not referrals out.

02

Fixed fees, in writing

Every engagement begins with a written, fixed-fee proposal. You know the scope and the cost before we begin — no hourly meters, no surprise invoices.

03

Coordinated, not siloed

We work alongside your attorneys, advisors, and home-country accountants — and refer legal questions to qualified counsel — so every part of your plan is in expert hands.

How It Works

A structured path, in three steps.

1

Confidential consultation

We review your facts and goals, and tell you plainly which path fits — whether that's a Streamlined submission, a Plan B analysis, or a U.S. entity structure.

2

Fixed-fee proposal

You receive a written engagement with defined phases, deliverables, and fees before any work begins.

3

Phased execution

We prepare and file through secure channels, keep you informed at every phase, and close with a clear plan for what comes next.

Take the First Step

The hardest part is the first conversation. Make it with a CPA.

Tell us where you are and where you're headed. We'll tell you, plainly, what your path forward looks like.
