Quick answer

The government's power to assess and collect taxes is not unlimited in time; the Tax Code provides prescriptive periods that protect taxpayers from indefinite exposure. As a general rule, internal revenue taxes must be assessed within three years from the last day prescribed by law for the filing of the return, or from the day the return was actually filed if filed late. However, this period is extended to ten years in cases of a false or fraudulent return with intent to evade tax, or a failure to file a return; in such cases, the tax may be assessed, or a proceeding for collection may begin without assessment, within ten years after the discovery of the falsity, fraud, or omission. Once a tax has been assessed, the BIR generally has a further period (five years from the assessment) to collect it by distraint, levy, or court proceeding. The running of these periods may be suspended in certain situations (such as when the taxpayer requests a reinvestigation that is granted, or the taxpayer cannot be located). If the BIR assesses or collects beyond the prescriptive period, the assessment or collection is barred, and the taxpayer may raise prescription as a defense. So even a valid tax liability can become unenforceable through prescription.

Limited Time to Assess

Taxes must generally be assessed within three years from the deadline for filing the return (or the actual filing date if late).

The Ten-Year Period

This extends to ten years for a false or fraudulent return with intent to evade, or a failure to file — counted from the discovery of the falsity, fraud, or omission.

Period to Collect

Once assessed, the BIR generally has a further five years to collect. The periods may be suspended in certain cases (e.g., a granted reinvestigation, or the taxpayer cannot be located).
