Nev. Admin. Code § 369.30 — 369.30

NAC 369.030    Receipt by Commission of reports, returns and remittances. ( NRS 360.090 , 369.150 )
1.  Any report, return or remittance to cover
a payment required by chapter 369 of
NRS, which is transmitted through the United States mail shall be deemed filed
or received on the date shown by the post office cancellation mark stamped upon
the envelope containing it, or on the date it was mailed if proof satisfactory
to the Nevada Tax Commission establishes that the document or remittance was
timely deposited in the United States mail, postage prepaid and properly
addressed to the Commission.
2.  A receipt for material sent by certified
or registered mail, if different than the post office cancellation mark, will
prevail if the date on the receipt is earlier than the cancellation date.
3.  A record authenticated by the post office
that the cancellation date on certain batches of mail was erroneous is proof
satisfactory to the Commission that the mailing was made on a date other than
the post office cancellation date.
4.  If it is known that the postal service
was inoperative at a certain time due to strikes, riots, warfare, acts of God or
other reasons, the Commission will consider the circumstances, and if there is
other evidence of timely mailing will accept the evidence and deem the return
or payment timely.
5.  The cancellation date affixed by a
postage meter in possession of the taxpayer or other person will be disregarded
as proof of the date mailed whenever it is contradicted by an official post
office cancellation mark stamped upon the envelope containing it. Statements by
a taxpayer or the taxpayer’s employees, alone, will not be sufficient to refute
the post office cancellation date as the date of mailing.
