RIZAL COMMERCIAL BANKING CORPORATION VS. COMMISSIONER OF INTERNAL REVENUE- Waiver of the Statute of Limitations

ISSUE:

Whether a taxpayer, by paying the other tax assessments covered by a Waiver of the Statute of Limitations, is consider estopped from questioning the validity of the said waiver (on the basis that the CIR did not sign it) with respect to the other covered but unsettled assessments?

HELD:

YES. RCBC is considered estopped through its partial payment of the revised assessments within the extended period provided in the said waivers. Thus, it had impliedly admitted the validity of the said waivers. Had it believed that the waiver was invalid and that the period to assess had effectively prescribed, RCBC could have refused to make any payment based on any assessment against it.
