How we think about accounting

Rules define boundaries, not outcomes

Regulations set the limits we work within, but good accounting is about understanding implications and choosing the right path within those limits.

Informed judgement

We stay closely informed on regulatory changes and current practice, so advice is based on context, experience, and what actually applies to you.

Knowing when to say no

Good advice isn’t always convenient. When something creates unnecessary risk or confusion, we are clear about it and don’t avoid difficult conversations.

Trusted Partnership

We work closely with our clients, building long-term relationships based on clarity, reliability, and professional responsibility.

Our Leadership And Professional Background

Atlantic Accounting is led by Yessica Aguiar and Tiago Correia, combining formal academic training with practical, client-focused accounting support.
Yessica Aguiar holds a Master’s degree in Accounting and is a certified accountant in Portugal.

Tiago Correia is a certified accountant with experience advising international clients

Together, we work closely with our clients to ensure that accounting decisions are technically correct, commercially sensible, and aligned with Portuguese regulations.

We take the time to understand each client’s situation and apply informed professional judgment. This leads to clear, responsible guidance — ensuring decisions are made within regulatory frameworks while carefully considering their tax position.

We support both ongoing accounting relationships and specific questions or situations.
If you’re unsure what you need, the initial conversation helps clarify whether and how we can assist.

The initial conversation is a practical discussion about your situation.
We ask questions, clarify what matters, identify any immediate issues, and explain what support — if any — would make sense going forward. There is no obligation to proceed.

Yes.

It’s a no-obligation conversation to understand your situation and determine whether we are the right fit.

Clarity and alignment matter to us.
If an engagement isn’t working as expected, we address it openly and early. If  expectations continue not to be met and alignment can’t be restored, the engagement is concluded and no charge is applied for the final month of service.

Yes. We regularly support short-term rental operators, including registration, ongoing accounting, and tax obligations.
If your situation has specific constraints or changes over time, we help you understand how those affect your position.

Our work is focused on Portuguese accounting and tax matters.
We regularly support clients who live abroad or have international elements to their situation.
