Dear Sir/Madam:

Here is for drafting a Protest Letter against a Tax Assessment in the Philippines, based on the National Internal Revenue Code (NIRC) as amended by the Tax Reform for Acceleration and Inclusion (TRAIN) Law and relevant BIR regulations.

This protest is filed without prejudice to any other remedies, including appeal to the Court of Tax Appeals (CTA) in case of denial. | Item | BIR Assessment | Taxpayer’s Corrected

We have attached our audited financial statements, general ledgers, and sales invoices (Annex “B”) showing that the alleged under-declared sales of P [amount] is double-counted.
