Tax defense, planning, and compliance before federal, state, and municipal authorities
The Tax practice of R&A Asociados offers comprehensive solutions in tax matters that combine legal defense, planning, and regulatory compliance. We assist companies and individuals at every stage of their relationship with the tax authorities: from a preventive review of their obligations to handling audits, negotiating tax assessments (créditos fiscales) and, where necessary, litigation before the TFJA (Federal Court of Administrative Justice) and amparo proceedings (Mexico's constitutional protection suit).
Our approach seeks to protect the taxpayer's interests and optimize their tax position before federal, state, and municipal authorities, always within the legal framework. We serve companies and individuals who need certainty in their transactions, whether to prevent tax contingencies, recover refundable balances, or respond to an act of authority (a government action) with a technical, timely, and properly documented strategy.

Frequently asked questions
A formal request (requerimiento), a letter of findings, or the start of an on-site audit carries legal deadlines for a response, and the way it is handled from the outset affects how the proceeding unfolds. It is advisable not to ignore it, to keep the document and its proof of service, and to review with a specialist what is being requested and what documentation supports your position. If you would like us to review your case, we will be glad to schedule a consultation.
Mexican law provides various means of defense against acts of the tax authorities, such as the appeal for revocation (recurso de revocación), administrative litigation before the TFJA, and amparo proceedings, each with its own requirements and deadlines, which are generally counted in business days from service of notice. Determining whether an act can be challenged and which avenue is appropriate requires reviewing the document and your particular situation. We invite you to schedule a consultation to analyze the available alternatives.
The firm handles refund and offset requests for refundable balances and, when the authorities deny them, partially reject them, or fail to rule in time, also takes on the corresponding defense, including the involvement of Prodecon in complaint or mediation proceedings. Each case requires a review of the documentation that supports the balance. We will be glad to schedule a consultation to assess your situation.
These answers are for guidance only; each case requires individual analysis.
