Process

How We Work

We Refer Out What We Don’t Need to Touch

If your situation needs only Portuguese compliance, we say so in writing and point you to a contabilista. We only engage when cross-border advisory adds value.

Defined Technical Accountability

Telmo Ramos leads the technical review and signs Tax Position Reviews and advisory deliverables within scope, supported by a focused cross-border team.

Income-by-Income, Treaty-by-Treaty

Every income stream is analysed against the specific treaty between your jurisdictions. This is how we find what generalist advisors miss. Example: when RSUs vest across a move to Portugal, we map each vesting period to the relevant jurisdiction and treaty rules before setting the reporting position. See related cross-border tax insights for practical treaty and regime examples, including US-Portugal treaty, FATCA, and FBAR, NHR to IFICI transition rules, and Portugal IRS filing mechanics.

We Show the Position We Didn’t Recommend

Every review includes a modelled alternative with projected numbers, the counter-argument considered, and residual risk. So you choose with data.

We Coordinate with Your Existing Advisors

We coordinate directly with your private bank, corporate legal, and home-country CPA so your filings stay aligned across jurisdictions.

Client Voices

Taxbordr Reviews

I came in with two late Portuguese returns, an inherited apartment sale, and some embarrassment about having waited too long. Telmo was direct about the exposure, but never dramatic. The work felt founder-led in the practical sense: one person understood the facts, challenged the weak spots, and stayed accountable for the advice.

You deal directly with the person doing the analysis. No account managers, no ticket numbers. When my situation changed a year later, I emailed and got a straight answer from the same person who already knew my file.

Your Situation Is Unique

A short conversation is the fastest way to know where you stand. Each engagement is defined-scope: deliverables and timeline are agreed before work starts. Not ready to book yet?

Why Taxbordr Uses a Documented Advisory Model

Cross-border cases break when diagnosis, execution, and sign-off are not aligned. Taxbordr keeps the Portugal-side position documented and coordinates the points that other advisers need from first review through final implementation.

The aim is institutional-grade analysis with named technical ownership: income-by-income, treaty-by-treaty work, led by the adviser who signs the Tax Position Review and supported by a focused team.
