About Taxbordr: founder-led complex asset reporting
Taxbordr is a Portugal-first international tax advisory practice led by Telmo Ramos, Ordem dos Economistas Cédula nº 16379, with prior experience at KPMG Luxembourg and EY Lisbon. Complex asset reporting is the engagement Taxbordr opens when the asset side of a Portuguese return needs more than a single Anexo G line: equity-compensation vesting across two countries, multi-wallet crypto disposals and staking flows, multi-rental property income (Cat F or Cat B), inherited assets needing basis documentation, or prior-year gaps that require continuity work. The deliverable is a structured schedule by asset class that plugs into the annual return and survives a later AT review.
Common triggers
RSU and stock-option vesting across two countries: equity comp where the grant, vest, and sale dates straddle Portuguese residency or two tax systems, and the cost basis, treaty allocation, and credit method need to be documented.
Multi-wallet crypto activity: disposals, swaps, staking, mining, lending, and Cat E versus Cat G classification under the three-category framework introduced from 2023 onwards. The 365-day rule applies only to one slice; the rest needs careful classification.
Multi-rental property income: multiple Portuguese or foreign properties, Cat F versus Cat B election, deductions, AIMI exposure, and continuity from prior-year filings.
Inherited assets: basis documentation under Portuguese rules, Imposto do Selo treatment for non-family transfers (10% under CIS art 6), and feeding inherited basis into Anexo G when the asset is later sold.
AT correspondence requesting backup: a notice asking for source documents on a previously reported gain, foreign asset, or rental flow, where the schedule needs to be rebuilt for the response.
Prior-year carry-forward issues: losses, deferred gains, capital-gains exemptions claimed in earlier years that need clean continuity into the current return.
Deliverable
A structured schedule by asset class with calculations, source documents tagged, and a short note explaining the position taken. Designed to plug into the annual return (Anexo G for capital gains, Anexo J for foreign-source income, Anexo F for rental, Anexo L for IFICI / grandfathered NHR), survive an AT review request, and carry forward cleanly into the next year. The note documents the assumptions, the treaty article applied where relevant, and the evidence path so a later reviewer can rebuild the analysis.
Foreign asset declaration scope
For Portuguese tax residents, foreign assets typically appear on Modelo 3 through income annexes (Anexo J for foreign-source income, capital gains on foreign assets) rather than a dedicated wealth declaration; Portugal does not currently impose a wealth tax beyond AIMI on real estate. Where the client has US-side reporting (FBAR, Form 8938), Taxbordr coordinates the asset schedule so the Portugal-side numbers and the US-side numbers reconcile. See FATCA Portugal for the US-side framework.
Out of scope
Investment advice (asset selection, allocation, or rebalancing)
Brokerage or wallet operations (custody, trading, signing)
Document acquisition (statements, exchange exports, notarised inheritance papers)
Home-country return preparation (the schedule supports it but does not replace it)
Pricing
From €450, scoped after record volume and asset classes are reviewed. Engagements with very high transaction counts (multi-thousand crypto entries, dozens of property events) or multi-year continuity work are quoted separately. The €500 Tax Position Review fee credits in full toward any engagement over €1,500 if the diagnostic preceded the schedule work.
Frequently Asked Questions
Does Taxbordr handle crypto across multiple wallets and exchanges?
Yes. The schedule consolidates disposals, swaps, staking, mining, and lending across wallets and exchanges into Cat E (passive yield) and Cat G (private capital gains) classifications under the three-category framework, with the 365-day-rule application documented per disposal where relevant.
How is RSU vesting handled when residency changes mid-grant?
The schedule documents grant, vest, and sale dates against the Portuguese residency timeline, applies the relevant treaty article (typically the employment article for vesting and the gains article for the eventual sale), and reconciles the cost basis used on the Portugal return with the cost basis used on the home-country return.
Does Portugal have a wealth tax?
Not in the conventional sense. Portugal does not have a stand-alone wealth tax. AIMI applies a progressive surcharge on the VPT (taxable property value) of Portuguese residential real estate above thresholds (currently 0.7% over €600,000 per owner, 1% over €1m, 1.5% over €2m). Foreign assets are not subject to AIMI. Foreign-source income on those assets is reported on Anexo J.
Can Taxbordr coordinate with my US tax preparer on FBAR / Form 8938?
Yes, through the schedule output. Taxbordr produces the Portugal-side schedule and supporting notes that the US preparer can reconcile against FBAR and Form 8938 reporting. Direct US filing is handled by the home-country preparer.
What does the €450 starting fee include?
A scoped asset schedule for one or two asset classes with moderate record volume (a single equity event, a small to mid-volume crypto position, two or three rental properties, or similar). Larger or multi-class engagements are quoted after a record review. The schedule plugs into the annual return; filing execution is a separate engagement.
