REVENUE MEMORANDUM ORDER NO. 26-2016 issued on June 14, 2016 prescribes the
policies and guidelines in handling disputed assessments, and in issuing Final Decision on
Disputed Assessment (FDDA) and revision thereof by the Commissioner of Internal Revenue
(CIR).
A taxpayer must be given an opportunity, if he/she/it so chooses, to explain his/her/its
objection to an assessment and present necessary documentation in support his/her/its objection,
before an FDDA is issued. A Protest against Preliminary Assessment Notice (PAN) is optional not
mandatory.
The Formal Letter of Demand and Final Assessment Notice (FLD)/(FAN) shall be issued
fifteen (15) days from date of receipt by the taxpayer of the PAN, whether the same was protested
or not. If the taxpayer, upon receipt of the PAN, accepts and pays the assessment either partially
or fully, an FLD/FAN shall be issued to formalize the assessment, and Payment Form 0605 shall
be duly prepared, filed and paid to acknowledge and provide evidence for the settlement of the
assessment or portion of the assessment paid.
Within thirty (30) days from receipt of the FLD/FAN, the taxpayer shall either accept the
assessment, fully or partially, and pay the amount due on the assessment accepted, or protest the
assessment fully or partially by filing either of the following remedies (the filing of one precludes
the filing of the other remedy):
a. Request for reconsideration if the taxpayer is not going to submit any other additional
evidence or documents and merely pleas for a re-evaluation of an assessment;
b. Request for reinvestigation on the basis of newly-discovered evidence or if the taxpayer
intends to present or submit additional evidence or documents.
After the issuance of the FAN/FLD, if the taxpayer accepts and settles/pays the assessment
in full, Payment Form 0605 shall be duly prepared, filed and paid. lf the taxpayer accepts and
settles/pays the assessment in part, and protest the remaining portion, Payment Form 0605 shall
be prepared, filed and paid for that portion of the assessment accepted and settled, and an FDDA
shall be issued for the portion of the assessment not settled and resolved. For that portion of the
assessment resolved in favor of the taxpayer, an Authority to Cancel Assessment (ATCA) shall be
prepared to evidence the cancellation of the assessment.
If a request for reinvestigation was made, the taxpayer shall submit all the relevant
supporting documents in support of his/her/its protest within sixty (60) days from the date of the
filing of the taxpayer’s letter of protest. Evaluation of the protest shall be based exclusively on the
documents submitted within this period, and no further document shall be accepted after the
expiration of the said period. The assessment shall become final and executory in the event the
taxpayer fails to submit the relevant supporting documents within this 60-day period, and a
Collection Letter and other collection remedies, such as but not limited to garnishment, warrant
and levy, shall be issued against the taxpayer.
All decisions on protest to the FAN, whether the taxpayer’s protest is accepted or denied
partially or wholly, shall be communicated to the taxpayer through the issuance of a FDDA. All
protest shall be considered a request for reconsideration, unless said protest clearly indicates that
the request is for reinvestigation. A request for reinvestigation shall be available in a protest to a
FAN/FLD only. After the issuance of an FDDA, a request for reinvestigation shall no longer be
available as a taxpayer remedy.
An FDDA shall be issued automatically if the protest is not acted upon by the
Commissioner’s duly authorized representative within 180 days (counted from the date of filing of
protest in the case of a request for reconsideration, or from the lapse of the 60-day period to submit
relevant document in the case of a request for reinvestigation), and the taxpayer appeals to the
Court of Tax Appeal within 30 days after the expiration of the 180-day period.
After the issuance of the FDDA, the taxpayer may accept and settle the assessment
contained therein, partially or fully. Payment Form 0605 shall be prepared, filed and paid for the
assessment accepted and settled by the taxpayer. lf the FDDA was issued by the Commissioner’s
duly authorized representative, the taxpayer shall, within thirty (30) days from receipt of the
FDDA, file a motion for reconsideration with the Commissioner of Internal Revenue or appeal to
the Court of Tax Appeal (CTA). ln appealing the protest to the CTA, the taxpayer shall manifest
and state that the appeal pertains only to the portion of the FDDA not settled and paid and shall
attach to their appeal a copy of the duly filed and paid Payment form 0605.
Appeal to the Commissioner or to the CTA of the FDDA shall not preclude the taxpayer
from voluntarily settling the assessment, partially or fully. Payment Form 0605 shall be duly
prepared, filed and paid and the taxpayer shall manifest before the CTA the fact of settlement of
the assessment, partially or fully, present the duly filed and paid Payment Form 0605, and file a
motion for dismissal with prejudice as to the assessment or portions thereof that has been settled
and paid on the ground that the appealed disputed assessment has become moot and academic.
An assessment shall become final, executory and demandable due to the following
grounds:
a. Failure of taxpayer to file a valid protest within thirty (30) days from receipt of the
FLD/FAN;
b. Failure of taxpayer to submit all relevant documents in support of his protest by way
of request for reinvestigation within sixty (60) days from the date of filing thereof;
c. Failure of taxpayer to appeal to the CIR or the CTA within thirty (30) days from date
of receipt of the FDDA issued by the Commissioner’s duly authorized representative;
d. Failure of taxpayer to appeal to the CTA within thirty (30) days from date of receipt of
the FDDA issued by the Commissioner;
e. Failure of taxpayer to timely file a motion for reconsideration or new trial before the
CTA Division or failure to appeal to the CTA En Banc and Supreme Court based on
existing Rules of Procedure; or
f. Failure of taxpayer to receive any assessment notices because it was served in the
address indicated in the BIR’s registration database and the taxpayer transferred to a
new address or closed/ceased operations without updating and transferring its BIR
registration or cancelling its BIR registration as the case may be.
