Tax assessment (BIR letters of authority)

Expert support for BIR letters of authority and tax assessments in the Philippines. We help organisations respond, negotiate and resolve audits effectively.

Receiving a Letter of Authority (LOA) from the Bureau of Internal Revenue is the start of a formal tax assessment. For large organisations, the process that follows can be resource-intensive and disruptive - particularly without experienced support in place from the outset.

We assist organisations at every stage of the tax audit process. This includes early-stage audit planning, document management, technical review of preliminary and final assessment notices, preparation of written protests, reconciliations of accounts and direct engagement with BIR examiners.

Our focus is on protecting our clients' tax positions through accurate, well-supported responses - while maintaining a constructive and professional relationship with the tax authority throughout the tax audit.
