Nevada Administrative Code Chapter 373 - County Taxes on Fuel
Background
NAC Chapter 373 regulates:
County fuel taxes for gasoline, diesel, and other motor fuels
Reporting and remittance requirements for distributors and retailers
Record-keeping for taxable fuel transactions
Enforcement, penalties, and interest for noncompliance
The Nevada Department of Taxation enforces these rules on behalf of counties.
Case 1: Failure to Remit County Fuel Taxes
Issue
A fuel distributor failed to remit county taxes collected on gasoline sales.
Facts
Distributor collected county fuel taxes from retailers but did not forward them to the appropriate county treasury.
Audit revealed a shortfall over multiple reporting periods.
Rules Applied
NAC 373.120 – Remittance requirements
NAC 373.150 – Filing and reporting duties
Board’s Analysis
Taxes collected on behalf of counties are held in trust for the public.
Failure to remit constitutes a violation and potential misappropriation of funds.
Outcome
Fines imposed for each month of noncompliance
Interest assessed on unpaid amounts
Requirement to implement internal controls for future remittances
Key Lesson
County fuel taxes must be remitted on time; collecting without remitting is a serious violation.
Case 2: Late or Inaccurate Fuel Tax Reporting
Issue
A retailer submitted reports with incorrect taxable fuel volumes and late filings.
Facts
Reports understated gallons sold by 15% for two consecutive months.
Filed reports were also received past the due date.
Rules Applied
NAC 373.130 – Accurate reporting requirements
NAC 373.140 – Timely filing standards
Board’s Analysis
Accurate reporting ensures correct tax distribution to counties.
Late and inaccurate reporting undermines county revenue and violates NAC rules.
Outcome
Penalties for late filing and underreporting applied
Interest charged on unpaid taxes
Mandatory staff training on record-keeping and reporting procedures
Key Lesson
Accuracy and timeliness in reporting are equally important as tax payment.
Case 3: Misclassification of Taxable Fuel
Issue
Distributor classified taxable fuel as exempt to reduce tax liability.
Facts
Diesel fuel intended for highway use was reported as off-road fuel.
Resulted in lower tax liability for county taxes.
Rules Applied
NAC 373.040 – Definition of taxable fuel
NAC 373.050 – Exemptions for certain fuel uses
Board’s Analysis
Misclassification is a violation even if unintentional; the distinction between taxable and exempt fuel is clearly defined.
Counties rely on accurate classification for revenue collection.
Outcome
Back taxes assessed for misclassified fuel
Penalties and interest applied
Required corrective reporting and future compliance monitoring
Key Lesson
Understanding taxable vs. exempt fuel is critical for distributors and retailers.
Case 4: Failure to Maintain Proper Fuel Records
Issue
Distributor could not provide supporting documentation for tax filings.
Facts
Audit revealed missing invoices and delivery receipts for taxable fuel.
Could not reconcile gallons sold with reports submitted.
Rules Applied
NAC 373.160 – Record-keeping requirements
NAC 373.170 – Retention and inspection of records
Board’s Analysis
Proper records are required to substantiate tax filings.
Missing records hinder audits and enforcement, which is a violation in itself.
Outcome
Fine imposed for noncompliance
Requirement to reconstruct records and maintain them for the statutory retention period
Follow-up audit scheduled
Key Lesson
Proper documentation is essential to prove compliance and avoid penalties.
Case 5: Incorrect Fuel Tax Payment Due to Software Error
Issue
A retailer’s accounting software miscalculated county taxes, resulting in underpayment.
Facts
Software incorrectly applied state instead of county tax rate.
Underpayment went unnoticed for several reporting periods.
Rules Applied
NAC 373.120 – Payment of county taxes
NAC 373.130 – Accurate reporting and remittance
Board’s Analysis
Even inadvertent underpayment is subject to penalties and interest.
Businesses are responsible for ensuring software systems correctly calculate taxes.
Outcome
Back taxes with interest assessed
Penalties reduced due to demonstrated good-faith effort
Requirement to validate tax software calculations regularly
Key Lesson
Technical errors do not exempt taxpayers from compliance responsibility.
Case 6: Interstate Fuel Shipment Misreporting
Issue
Distributor failed to report fuel transported across county lines properly.
Facts
Fuel shipped from one Nevada county to another was reported as local sales.
Counties did not receive correct tax allocations.
Rules Applied
NAC 373.060 – Allocation of county taxes for transported fuel
NAC 373.130 – Accurate reporting requirements
Board’s Analysis
Accurate reporting is essential for fair allocation of county taxes.
Misallocation deprives counties of revenue and is a clear NAC violation.
Outcome
Adjustment of tax payments to correct county allocations
Penalties and interest assessed
Mandatory internal process review for multi-county shipments
Key Lesson
Inter-county fuel movement must be reported correctly to ensure proper tax distribution.
Case 7: Attempted Evasion of County Fuel Tax
Issue
Distributor deliberately underreported sales to avoid county tax.
Facts
Sales were partially “off-the-books.”
Evidence suggested intentional evasion of county fuel tax obligations.
Rules Applied
NAC 373.120 – Remittance of taxes collected
NAC 373.150 – Enforcement and penalties
Board’s Analysis
Intentional evasion is considered a serious violation, potentially criminal.
Protecting county revenue is the primary goal of the statute.
Outcome
Significant fines and back taxes assessed
Referral to law enforcement for further investigation
License suspension or revocation considered
Key Lesson
Intentional evasion carries severe penalties and legal consequences.
Overall Themes from NAC 373 Cases
Timely remittance of county fuel taxes is mandatory.
Accurate reporting and classification of fuel are critical.
Proper record-keeping is required for audits and verification.
Errors, even unintentional, are penalized, though good faith can mitigate.
Intentional evasion or fraud can lead to criminal investigation and severe penalties.
