Overview
Operating a commercial fleet across state lines requires ongoing compliance with a layered set of federal and state regulations. Two of the most operationally significant frameworks are the International Registration Plan (IRP) and the International Fuel Tax Agreement (IFTA). Both programs impose recurring filing obligations with real financial and operational consequences for non-compliance.
DOCKEX exists to reduce the administrative burden of these obligations. Our platform automates data collection, calculations, and return preparation, helping fleet operators submit accurate filings on time, maintain organized records, and respond quickly to audits or jurisdictional inquiries.
This page describes how DOCKEX supports compliance across each regulatory dimension, how we handle the data that underpins your filings, and the limits of what our platform can and cannot do on your behalf.
IRP Compliance
What is IRP?
The International Registration Plan is a reciprocal agreement among the 48 contiguous U.S. states and the District of Columbia that governs the apportionment of vehicle registration fees for commercial motor vehicles traveling in two or more member jurisdictions. Carriers register through their base jurisdiction and pay fees distributed to each member state based on the proportion of miles traveled there.
How DOCKEX Helps
DOCKEX supports every stage of the IRP lifecycle. For Oklahoma-based fleets we file directly with the state; everywhere else we prepare the renewal package and you submit it. Our platform helps you:
- Organize and submit accurate IRP applications to your base jurisdiction, with structured data entry that reduces transcription errors.
- Manage apportioned registration credentials across all member jurisdictions, including cab cards and registration renewals.
- Track renewal deadlines with automated compliance calendar alerts, so you never operate on expired credentials.
- Maintain vehicle-level distance records to support accurate apportionment calculations and defend against jurisdictional audits.
- Handle fleet additions, deletions, and transfers mid-registration year with accurate supplemental filings.
Accuracy Commitments
IRP fees are calculated based on reported mileage per jurisdiction. Inaccurate mileage data leads to either overpayment or potential audit findings. DOCKEX applies validation logic to your distance data before it surfaces in any application, flagging anomalies for your review. Final review and submission responsibility remains with the operator or their designated representative.
We retain all mileage inputs, calculation records, and submission history in your account for a minimum of four years (aligned with standard IRP audit lookback windows), so you can reconstruct any filing if a jurisdiction initiates a review.
IFTA Compliance
What is IFTA?
The International Fuel Tax Agreement simplifies the reporting of fuel use taxes by interstate motor carriers. Qualified motor vehicles operating in two or more member jurisdictions must file quarterly fuel tax returns with their base jurisdiction. IFTA determines the net tax owed or refundable to each jurisdiction based on miles traveled and fuel purchased within that jurisdiction.
How DOCKEX Helps
IFTA compliance requires precise recordkeeping for every qualified motor vehicle in your fleet, every quarter, every year. DOCKEX automates the most labor-intensive parts of this process:
- Aggregate mileage data by jurisdiction across your fleet, eliminating manual spreadsheet work and reducing the risk of transposition errors.
- Consolidate fuel purchase records (fuel type, gallons, and purchase jurisdiction) in a single structured ledger.
- Apply current jurisdictional fuel tax rates to calculate net tax due or refundable per jurisdiction for each quarterly return.
- Prepare completed IFTA quarterly returns ready for your review and submission to your base jurisdiction.
- Send deadline reminders for each quarterly filing period (January 31, April 30, July 31, October 31) so no return is missed.
Quarterly Filing Support
Late IFTA filings incur penalties and interest in most jurisdictions. DOCKEX surfaces your quarterly filing status on a dedicated compliance dashboard with clear due-date visibility. Prepared returns are stored within your account with full audit trails, including the mileage records, fuel data, and rate tables used to produce each return.
If your base jurisdiction conducts an IFTA audit, your DOCKEX account provides a centralized source of the vehicle data, fuel records, and quarterly return history required to complete the examination. Each filed return can be exported as a PDF for submission to auditors or your own records.
FMCSA & USDOT
The Federal Motor Carrier Safety Administration (FMCSA) and the U.S. Department of Transportation (USDOT) require commercial motor carriers to maintain registrations and operating authority that are current and consistent with their DOT records. Discrepancies between a carrier's USDOT number, operating authority, and state registrations can result in out-of-service orders, civil penalties, and loss of operating authority.
DOCKEX helps fleet operators maintain consistency between their federal and state records by:
- Storing your USDOT number, MC number, and associated carrier information in a central fleet profile used across all IRP applications and regulatory filings.
- Flagging registration gaps or expiration risks on your compliance calendar before they create federal record inconsistencies.
- Maintaining a complete history of vehicle additions and deletions so your registered fleet reflects your operating fleet at all times.
On Professional and Business plans, DOCKEX prepares and submits MCS-150 biennial updates on your behalf with your authorization on file. On Starter, DOCKEX prepares the update and tracks the deadline for you to submit through official FMCSA channels. Carriers remain responsible for the accuracy of the underlying operating data. See our methodology page for the exact filing scope behind every "we file on your behalf" statement.
State Regulatory Compliance
DOCKEX currently serves commercial fleet operators based in the State of Oklahoma. Oklahoma-registered carriers file IRP apportioned registrations and IFTA quarterly returns through the Service Oklahoma and the Oklahoma Department of Public Safety. DOCKEX supports these filing workflows for Oklahoma-based fleets operating across member jurisdictions within the contiguous United States.
Beyond IRP and IFTA, Oklahoma carriers may be subject to additional federal and state requirements including unified carrier registration (UCR) filings, USDOT number maintenance, and permit requirements for oversize or overweight vehicles. DOCKEX surfaces applicable compliance deadlines in your compliance calendar. Coverage and automation depth vary by requirement.
Operators with questions about specific Oklahoma filing requirements should consult the Service Oklahoma, the Oklahoma Department of Public Safety, or a licensed transportation compliance consultant familiar with Oklahoma regulations.
Data Compliance
The integrity of your regulatory data is foundational to DOCKEX's value. We apply the following practices to ensure the data that drives your filings is accurate, complete, and available when you need it:
Data Retention
All mileage records, fuel purchase data, filing submissions, and supporting documentation are retained for a minimum of four years from the date of the applicable filing period. This aligns with standard IRP and IFTA audit lookback windows and supports your ability to respond to jurisdictional inquiries.
Audit Support
When a jurisdiction initiates an IRP or IFTA audit, your DOCKEX account provides structured access to the trip records, fuel data, calculation history, and submitted returns needed to complete the examination. IFTA quarterly returns and IRP Schedule A and B documents can be exported as PDF for direct submission to auditors.
Input Validation
DOCKEX applies automated validation logic to mileage inputs and fuel data before they populate any filing. Anomalies (such as implausible per-vehicle mileage figures or jurisdictional mismatches) are flagged for operator review before submission.
Rate Accuracy
IFTA fuel tax rates are maintained by the DOCKEX team and applied to the applicable reporting period. IRP registration fees follow the Oklahoma statutory fee schedule. Rate tables used for each return are versioned so any filing can be reconstructed and reviewed after the fact.
DOCKEX does not alter, delete, or anonymize regulatory records during the applicable retention period. Account holders may export their complete data at any time and retain copies independently.
Our Platform Compliance
In addition to supporting your regulatory obligations, DOCKEX maintains its own compliance practices governing how we collect, store, process, and protect your data.
- Privacy: We collect only the data necessary to operate the platform and support your filings. We do not sell or share your data with third parties for marketing purposes. For a complete description of our data practices, see our Privacy Policy.
- Security: Customer data is encrypted in transit (TLS 1.2+) and at rest. Access controls, audit logging, and regular security reviews are in place to protect your fleet records and business information. See our Security page for full details.
- Access Controls: Account access is scoped by role. Fleet administrators control who can view, edit, and submit filings within their organization. All privileged actions are logged with timestamps and user attribution.
- Subprocessors: DOCKEX uses a limited set of trusted third-party infrastructure providers to operate the platform. These providers are contractually bound to data protection standards consistent with our own. A current list of subprocessors is available upon request at contact@dockex.io.
