Summary
Department
of Taxation
While control weaknesses have had the most significant effect on the estate tax, fuel taxes and short-term auto lease fees would also benefit from strengthened controls. For example, methods for reviewing fuel tax filings do not ensure taxes due are efficiently identified and collected. Additional weaknesses affecting all excise taxes exist in the areas of cash receipts and computer security
Principal Findings
·
The Department has not established a system for tracking
estate tax accounts. As a result,
billings and refunds were not always processed timely or accurately. For example, the Department took an average
of 120 days to bill eight of the receivables we tested; another four
receivables were never billed. In
addition, it took an average of 5 months for the Department to process the 34
refunds we tested and another 7 had not yet been processed. Finally, four of the accounts tested were
either billed or received refunds that were incorrect. (page 10)
·
There are no estate
tax policies or procedures for determining when to assess penalties and
interest or the type of documentation required to waive penalties and
interest. As a result, we found several
instances where penalties and interest were not assessed consistently among the
accounts reviewed. (page 10)
·
The Department has not
adopted regulations for the estate tax requiring sufficient documentation of
the amount of tax due, as required by NRS 375A.150(2). Consequently, the documentation submitted by
estates varies and the Department must frequently request additional information. (page 13)
·
Procedures for
processing payments of excise taxes do not ensure the payments are adequately
safeguarded. For example, checks
received for excise taxes are not endorsed until after they have been handled
by at least three persons. In addition,
duties for processing estate tax receipts are not adequately segregated. (page 14)
·
The Department did
not always respond timely to taxpayers’ written requests for waivers of penalty
and interest assessed on delinquent fuel taxes. It took from 5 to 11 months for the Department to respond to six
of the eight requests for waivers we reviewed.
NRS 360.293 requires the Department respond to written requests from
taxpayers within 30 days. (page 15)
·
The Department needs to strengthen management controls
regarding the efficient completion of desk reviews of fuel tax filings. The purpose of a desk review is to ensure
dealers accurately report gallons of taxable fuel sold in the State. Department staff attempt to perform desk
reviews of every tax form filed every month.
Our analysis of the information provided by the Department indicates
only 16% of dealers filing a return with taxable activity had any findings from
desk reviews during the first 6 months of calendar year 1998. By using a risk-based approach to select tax
filings for review, the Department could ensure adequate coverage and encourage
dealer compliance, while limiting the amount of resources required to complete
the reviews. (page 16)
·
While the Department
has developed some policies related to computer network security, it could
enhance controls over its network by adopting a comprehensive security
plan. In addition, some software
applications used for excise tax administration were not adequately tested or
documented. (page 17)
