Why a Founder-Led Portugal Expat Tax Advisory Exists

Telmo Ramos spent years inside Big 4 tax practices — first at KPMG in Luxembourg, then at EY in Lisbon. The work was sophisticated, but expats with genuine complexity were often caught in a void: too small for a Big 4 partner's attention, yet too layered for a local advisor who may not routinely analyse double taxation agreements. That gap is why clients searching for an international tax advisor in Portugal often choose a founder-led model.

Founder-led Portugal expat tax advisory timeline - KPMG Luxembourg to Taxbordr

Taxbordr was founded to close that gap. The analysis is institutional grade — income-by-income, treaty-by-treaty. The delivery is boutique: founder-led, direct access, no handoffs. Every Position Memo is signed by Telmo because he performs the underlying analysis himself.

The Team Behind Your Tax Position

Each engagement begins and ends with Telmo. You work directly with the advisor doing the analysis, while a lean coordination network supports implementation across jurisdictions.

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.

Founder-led accountability

Every planning call, every Position Memo draft, and every advisory sign-off is Telmo’s. There is no associate layer to delegate to.

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.

We show the position we didn’t recommend

Every memo 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.
