Just Got Your IFTA License? First Steps for New Motor Carriers

You just received your motor carrier authority, and now you need to deal with IFTA. The International Fuel Tax Agreement covers fuel tax reporting for commercial vehicles that operate across state lines. If you're running qualified motor vehicles in more than one jurisdiction, IFTA registration isn't optional — it's required before your first interstate trip.

The good news: IFTA is a cooperative agreement that simplifies what would otherwise be a nightmare of filing separate fuel tax returns in every state you enter. Instead, you file one quarterly return through your base jurisdiction, and IFTA handles the distribution of taxes to every state where you operated. The bad news: the paperwork and record-keeping start immediately, and getting it wrong early creates problems that compound over time.

In this guide, you will learn:

• Whether your vehicles qualify for IFTA (and when they don't)
• How to choose your base jurisdiction
• How to apply for an IFTA license and decals
• What records to keep from day one
• Your first quarterly filing timeline
• Common mistakes new carriers make with IFTA

Do You Need an IFTA License?

IFTA applies to qualified motor vehicles that travel in more than one IFTA member jurisdiction. A qualified motor vehicle is any vehicle used, designed, or maintained for the transportation of persons or property that meets either of these criteria:

• Has two axles and a gross vehicle weight (GVW) or registered gross vehicle weight (RGVW) exceeding 26,000 pounds
• Has three or more axles regardless of weight
• Is used in combination (tractor-trailer) when the combined weight exceeds 26,000 pounds

If your vehicle meets those criteria and operates in at least two IFTA jurisdictions (48 US states plus 10 Canadian provinces), you need an IFTA license. Vehicles that only operate within a single state are exempt from IFTA, though they still owe state fuel tax through other mechanisms.

Vehicles Exempt From IFTA

• Recreational vehicles (unless used for commercial purposes)
• Government vehicles
• Vehicles operating under trip permits instead of IFTA credentials
• Buses used for personal transportation of passengers (school buses operated by government entities)

Trip permits are an alternative to IFTA for carriers that only occasionally cross state lines. Most states sell temporary trip permits (typically 24–72 hours) that cover fuel tax for a single trip. However, if you're regularly operating interstate, trip permits quickly become more expensive and burdensome than an IFTA license.

Choosing Your Base Jurisdiction

Your base jurisdiction is the IFTA member state or province where your fleet is registered, where your vehicles are dispatched from, or where you maintain operational control. For most new carriers, this is simply your home state — the state where your business is located and where your trucks are based.

Your base jurisdiction is important because:

• You apply for your IFTA license there
• You file all quarterly returns through that state
• You make all IFTA tax payments to that state (which then redistributes to other jurisdictions)
• Audits are conducted by your base jurisdiction on behalf of all member states

You cannot cherry-pick your base jurisdiction to get a lower tax rate. IFTA rules specify that your base jurisdiction must be where you have an established place of business. If you have operations in multiple states, it's where your fleet's mileage is accrued or dispatched, or where the vehicles are maintained.

How to Apply for an IFTA License

The application process varies slightly by state, but the general steps are the same everywhere:

1. Contact your base jurisdiction's IFTA office. This is typically within the state's department of revenue, motor vehicle division, or transportation department. Most states have an online application portal.
2. Submit the IFTA application form. You'll provide your business information (legal name, EIN, DOT number, MC number), a list of vehicles to be registered under IFTA, and contact details.
3. Pay the licensing fee. Fees vary by state but are typically $5–$10 for the license itself, plus $2–$5 per set of decals (one set per vehicle).
4. Receive your IFTA license and decals. The license is a single document that covers your entire fleet. Decals are issued in pairs — one for each side of each vehicle. They must be displayed on the exterior of the cab.

Processing time ranges from a few days (for online applications in some states) to 2–4 weeks by mail. Plan ahead — you cannot legally operate interstate without IFTA credentials or a trip permit.

IFTA Decals

IFTA decals are renewed annually. Each calendar year requires new decals. When you first register, you'll receive decals for the current year. Decals must be placed on the exterior of the cab, one on each side, and must be clearly visible. Expired or missing decals can result in citations during roadside inspections.

If you add a vehicle mid-year, you'll need to order additional decals from your base jurisdiction. Most states process additional decal requests within a few business days. Until the decals arrive, carry a copy of your IFTA license and the decal order confirmation in the vehicle.

Setting Up Record-Keeping From Day One

IFTA requires detailed records of every mile driven and every gallon of fuel purchased. Starting with clean habits from your first trip prevents the scramble that happens when new carriers try to reconstruct records months later at filing time.

Mileage Records You Must Keep

For every trip, you need documentation showing:

• Date of the trip
• Trip origin and destination
• Route of travel (states entered and exited)
• Total trip miles
• Miles driven in each state
• Vehicle identification (unit number or license plate)
• Beginning and ending odometer or hub readings

Acceptable documentation includes individual trip sheets, driver logs, GPS tracking data, or any combination that provides a complete record. Many carriers rely on GPS-based tracking apps that automatically record state-by-state mileage, eliminating manual trip sheets entirely.

Fuel Records You Must Keep

For every fuel purchase, you need:

• Date of purchase
• Name and address of the fuel vendor (city and state at minimum)
• Number of gallons purchased
• Fuel type (diesel, gasoline, etc.)
• Price per gallon or total cost
• Vehicle identification

Fuel receipts are the primary documentation. Fleet card transaction reports are excellent because they capture all the required data points automatically. If a driver pays cash, the receipt must still include all the information above. A credit card statement showing a dollar amount at a truck stop is not sufficient — it doesn't show gallons.

How Long to Keep Records

IFTA requires you to retain all records for a minimum of four years from the filing date or due date of the return, whichever is later. If you file your Q1 2026 return on April 25, 2026, you must keep the supporting records until at least April 30, 2030 (four years from the due date).

Your First Quarterly Filing Checklist

Here is a step-by-step checklist for your first IFTA quarterly return:

1. Determine your reporting quarter. IFTA quarters follow the calendar: Q1 (Jan–Mar), Q2 (Apr–Jun), Q3 (Jul–Sep), Q4 (Oct–Dec). Your first return covers from the date you started operating under IFTA through the end of that quarter.
2. Compile total miles by vehicle. Add up each vehicle's total miles for the quarter using odometer readings or GPS data.
3. Break down miles by state. For each vehicle, determine how many miles were driven in each jurisdiction. This is the most labor-intensive step if done manually.
4. Compile total fuel by state. Organize all fuel receipts by jurisdiction. Total the gallons purchased in each state.
5. Calculate fleet MPG. Total miles (all vehicles) ÷ total gallons (all vehicles) = fleet MPG.
6. Complete the return form. Enter miles and fuel for each jurisdiction. The form calculates taxable gallons, net taxable gallons, and tax due per state.
7. Submit and pay. File through your base jurisdiction's portal. Pay any tax owed by the deadline.
8. File your records. Store all supporting documentation (trip sheets, fuel receipts, the filed return) for at least four years.

First-Quarter Filing Timeline

If you received your IFTA license in Q1 2026, here's your timeline:

Don't wait until April 29 to start compiling records. New carriers consistently underestimate how long it takes to sort through a quarter's worth of fuel receipts and trip data, especially when the record-keeping system wasn't established from the start.

Common Mistakes New Carriers Make

Operating Without Credentials

Driving interstate without IFTA decals or a trip permit is a violation that results in fines at weigh stations and roadside inspections. Some states impound vehicles without proper IFTA credentials. Get your license and decals before your first interstate trip.

Not Tracking From Day One

Many new carriers focus on getting loads and worry about paperwork later. By the time the first quarterly filing deadline arrives, they're scrambling to reconstruct three months of trip data from memory. Start tracking miles and saving receipts from your very first trip.

Underestimating Record-Keeping Requirements

A shoebox of gas station receipts isn't a record-keeping system. IFTA requires organized, verifiable records that an auditor can cross-reference. Set up a simple system — a folder per month, organized by vehicle, with both mileage logs and fuel receipts — and maintain it consistently.

Forgetting to File Zero Returns

If you hold an IFTA license but didn't operate in a given quarter (truck was in the shop, between contracts, etc.), you still must file a return showing zero miles and zero fuel. Failing to file — even a zero return — results in penalties and can lead to license revocation.

Confusing IFTA With Other Tax Obligations

IFTA only covers fuel tax. It does not replace your annual HVUT (Heavy Vehicle Use Tax) filing on Form 2290, state registration fees, or other permits. New carriers sometimes assume their IFTA license covers all tax obligations related to their trucks. It does not.

Frequently Asked Questions

How much does an IFTA license cost?

The license fee varies by state but is typically $5–$10. Decals cost $2–$5 per set (two decals per vehicle). The total cost for a single-truck operation is usually under $20. The real cost of IFTA is the time spent on record-keeping and filing, not the licensing fee.

Can I operate interstate while waiting for my IFTA decals?

Most states allow you to operate with a temporary IFTA permit or a copy of your license application receipt while waiting for decals. Check with your base jurisdiction. Some states issue temporary credentials electronically that you can print and carry in the cab.

What if I only cross into one other state occasionally?

If your interstate trips are infrequent (a few times per year), trip permits might be simpler than maintaining an IFTA license. However, once you're running interstate regularly, IFTA is more economical and less hassle than buying individual trip permits every time.

Do I need IFTA if I have a DOT number?

Having a DOT number and needing an IFTA license are separate requirements. You can have a DOT number for intrastate operations without needing IFTA. You need IFTA only when you operate qualified motor vehicles across state lines. Most interstate carriers need both a DOT number and IFTA credentials.

What happens if I get audited as a new carrier?

New carriers are not specifically targeted for audits, but they aren't exempt either. IFTA audits are typically random or triggered by anomalies in filed returns (unusual MPG, inconsistent reporting). If audited, the auditor will request your mileage records, fuel receipts, and vehicle documentation for the audit period. Having organized records from day one makes an audit manageable rather than catastrophic.

Bottom Line

Getting your IFTA license is one of the first administrative tasks a new interstate carrier needs to handle. The process itself is simple — apply through your base jurisdiction, pay a small fee, and display your decals. The ongoing obligation is where discipline matters: tracking every mile in every state, saving every fuel receipt, and filing quarterly returns on time. Carriers that set up proper tracking from the start avoid the painful catch-up game that plagues those who put it off. FleetCollect helps new carriers get IFTA right from the beginning with automatic GPS-based state mileage tracking and fuel logging, so your first quarterly filing is based on real data rather than estimates.
