Who should we contact?

Protected by OCC professional confidentiality.

Without a valid email we cannot link the question to you or send follow-up notices.

How it works

From question to solution in three steps.

Tell us what happened. The team identifies what is needed and supports you until the issue is resolved.

Send your question

Describe the problem and attach any documents that help us understand the case.

Receive an assessment

The initial assessment is always free. If additional work is needed, you first receive a proposal with the price and timeframe.

Resolve it with support

If you accept the proposal, we continue in the private chat, by email or in a scheduled meeting, with specialist review, until the issue is fully resolved.

Simplification is part of good service

Tax knowledge still falls short of the importance of taxation.

The academic research behind this project assessed VAT literacy among 533 participants. Although 85% of the sample had higher education, the average score remained at a sufficient level — clear evidence that tax needs more accessible explanations connected to real life.

3.99/8

Average correct answers across the eight VAT knowledge questions — a sufficient qualitative result.

57%

Answered four or fewer of the eight VAT knowledge questions correctly.

32%

Would seek a specialist — an accountant or tax adviser — when in doubt.

97%

Considered greater promotion of fiscal citizenship and tax literacy necessary.

Professional confidentiality

Confidential from the first contact.

Facts, documents and information obtained during professional work are handled under the confidentiality duty in the OCC Code of Ethics. A Portuguese tax number can be provided with the request and remains protected in the private case.

Do not send passwords or credentials unless expressly requested by the team. If access to a platform is needed to resolve the case, the safest method will be agreed with you. You may request anonymity in the case view.

The team

Clear expertise. Close support.

Each case is assigned according to its subject and complexity, with identified authorship and continuity through to resolution.
