Tax and social security disputes require swift, informed action to avoid escalating financial or legal consequences. At Frontier Tax Solutions, we offer specialised advisory and representation for individuals and businesses facing irregularities, debts, or enforcement procedures involving the Autoridade Tributária (AT) or Segurança Social (SS).
Our priority is to assess your case with precision, resolve issues efficiently, and ensure full compliance, always with discretion, clarity, and technical accuracy.
We analyse your debt situation and handle the negotiation of structured payment agreements (plano prestacional), interest reduction, and potential relief from penalties.
We act on your behalf in all communications with the Tax Authority or Social Security, ensuring timely responses, document submission, and legal clarity.
We prepare and submit amended declarations (declarações de substituição) when necessary, correcting previous omissions or errors while minimising exposure to fines.
We intervene to resolve enforcement actions that result in frozen accounts or blocked refunds, identifying the cause and acting within the legal timeframe.
We support clients under review or inspection, preparing documentation, legal arguments, and procedural defences as required.
