Portuguese companies must withhold 25% of payments to foreign suppliers — unless they hold the right treaty paperwork in advance. We audit your suppliers, secure the documentation, and bring that rate down to as low as 0%.
Add the foreign suppliers you pay, with their monthly cost and number of users or accounts. We estimate your annual spend and the maximum withholding tax at stake — the amount you risk overpaying or carrying as a liability without treaty documentation.

You don't chase suppliers and tax offices. We turn a messy Payables list into treaty-ready documentation.
We audit your supplier list and Modelo 30 and quantify the exposure.
We handle each supplier's 21-RFI, TRC and NIF. You only pay per document delivered.
An annual subscription keeps everything renewed and archived.
Ad hoc advisory, including reclaiming over-withheld tax.
Lets us deliver value quickly, so your onboarding is near-instant.
Stop withholding 25% when the treaty rate is 5% or 0%. That difference goes back to your supplier relationship.
If the paperwork is missing, YOU — not the supplier — owes the unpaid tax plus penalties. We close that gap.
A fixed-price audit, plus a flat fee per supplier. A fraction of the tax at stake, and cheaper than your team doing it one supplier at a time.
