1. Tax Accounting Principles
Under the all events test, accrual of income or expense occurs when all events have taken place that fix the right to receive or the liability to pay, and the amount can be determined with reasonable accuracy. In accumulated earnings taxation, the immediacy test determines whether profit retention serves the immediate or reasonably anticipated needs of the business, justifying non-distribution.

2. Tax Assessment Waiver
A waiver of the statute of limitations is a bilateral agreement between the taxpayer and the BIR extending the assessment or collection period. Executing a valid waiver defers the defense of prescription until the extended expiry date. However, an invalid or defective waiver confers no authority on tax officials and does not deprive the taxpayer of invoking prescription.

3. Local Business Taxation
Under Section 143(e) of the Local Government Code, local business tax on contractors is computed based on gross receipts for the preceding calendar year. Conversely, under Section 145, a retiring business pays local business tax based on gross sales or gross receipts realized during the current calendar year up to the date of business retirement.
