# IFTA Audit Defense
When an IFTA audit selects your carrier, defense matters. Goal: minimize additional tax + penalties.
## Initial response (within 30 days of notice)
- Acknowledge receipt
- Request copies of audit notification
- Ask for specific records they want to see
- Note the audit period (which quarters)
## Records to gather
- Quarterly returns for the audit period
- Fuel receipts (organized by quarter + state)
- Mileage records (ELD or trip sheets)
- Vehicle records (VINs, plate numbers, gross weight)
- Tax-paid fuel logs
- Sales invoices and receipts
## During the audit
- Auditor visits your office (or you ship records)
- Sample period selected
- Records reviewed in detail
- Discrepancies identified
- Adjustments calculated
- Initial findings shared
## How to defend
1. **Documentation quality** — well-organized, complete records reduce audit time + findings
2. **ELD data** — when available, ELD is highly persuasive
3. **Reasonable explanation** — for any anomaly, have a story (driver took different route, weather event, etc.)
4. **Industry comparison** — if your data is consistent with industry norms, that helps
5. **Personal use exclusion** — if you exclude personal use, show your accounting
## Common audit findings + defenses
- **Mileage shortfall**: actual miles > reported. Defense: re-examine the data source; may be auditor error.
- **Fuel allocation off**: state distribution doesn't match actual operation. Defense: provide route documentation.
- **Tax-paid double-counting**: same fuel claimed twice. Defense: receipts show single purchase; cross-reference dates.
- **Personal use miles**: claimed as business. Defense: provide written personal-use policy + driver records.
## After the audit
- **No additional tax**: you're done.
- **Small adjustment**: pay it; document the change in your books.
- **Significant adjustment**: request administrative review (state-level appeal).
- **Egregious finding or penalty**: consider attorney representation.
## Right of appeal
- Administrative review (typically 30 days to request)
- State-level hearing (varies by state)
- Civil action (rare, time-consuming)
## Compass IFTA module
- Pre-builds audit-ready data export
- Cross-references ELD + fuel + mileage data
- Identifies anomalies your auditor would flag
- Suggests reasonable explanations for variances
## CFR citations
- **IFTA Articles of Agreement**
- **IFTA Audit Procedures Manual**
## How Compass surfaces this
Searchable in Compass Ask. Runs against carrier fleet data when invoked from the relevant tracker. Read-only; no actions without explicit user approval.
