1. One Audit Rule
Under Section 235 of the National Internal Revenue Code, a taxpayer's books of accounts and accounting records shall generally be subjected to examination and inspection only once for any given taxable year. This statutory limitation protects taxpayers from administrative harassment, repetitive tax audits, and arbitrary demands by tax examiners. However, the general prohibition against multiple examinations of books of accounts is not absolute and admits specific statutory exceptions under national tax law.
2. Fraud Exception
Section 235 of the Tax Code explicitly provides an exception to the single-examination rule when the Commissioner of Internal Revenue discovers fraud, irregularity, or mistakes in the taxpayer's return. Where reasonable grounds exist to suspect that a tax return is fraudulent, a second tax audit may be lawfully authorized through a new Letter of Authority. The discovery of fraud nullifies the protection of the one-audit rule, allowing full re-investigation.
3. Letter of Authority
A Letter of Authority is the official statutory instrument that empowers a revenue officer to examine a taxpayer's accounting books and assess deficiency internal revenue taxes. When a re-examination is justified under statutory exceptions such as fraud or irregularity, the issuance of a valid Letter of Authority by authorized tax officials is mandatory to confer jurisdiction. An assessment resulting from a re-audit without a valid Letter of Authority is void.
