Want it done correctly without the back office? Argus IFTA handles the miles, the fuel, the optimization, and the filing.
Before you click any of these links.
Don't mess it up. Here is what you are signing up for.
You are personally liable.
The signature on the IFTA return is yours. Audit findings, penalties, and interest follow the carrier, not the software.
Audits hit ~1 in 30 carriers per year.
Every IFTA jurisdiction is required by the IFTA Articles of Agreement to audit at least 3% of its base carriers annually. Findings average several thousand dollars per audit.
Errors back-bill 3 to 5 years.
A single misclassified jurisdiction reopens prior quarters. Interest compounds monthly per jurisdiction across the entire lookback window.

Records must be kept 4 years.
Mileage logs, fuel receipts, trip sheets, GPS data, all retained for the IFTA records retention period. Lose them and the auditor estimates against you.
Or hand it to us and go drive.
Most filing services charge $25 to do the math and leave you holding the audit. CPAs want a few hundred a month and your spreadsheets. Argus already has your mileage from the nav app. Filing is the last step, and we do it correctly.
Audit defense included. Records retained for the full 4 year IFTA period.

United States · 48 states
Texas
Texas requires mileage AND fuel detail by jurisdiction in the same return. One transposed receipt forces a refile, and the system flags the account for closer review on the next quarter.
California
California reconciles your IFTA against the Interstate User Diesel Fuel Tax (DI program) on the same filing. Get one wrong and both can trigger a notice. CDTFA audits are among the most thorough in the country.
Florida
Florida charges a separate Pollutants Tax on fuel use in addition to the IFTA tax. The IFTA portal collects both and a single missed line item rejects the entire return.
Georgia
Georgia requires the Tax Center login and the IFTA account to be linked correctly before the first filing. Skip the link step and your return is filed against the wrong account, which counts as not filed at all.
Ohio
Ohio applies the IFTA tax PLUS the Commercial Activity Tax (CAT) for in-state revenue. Different return, different deadline, easy to confuse the two and underpay one of them.
Indiana
Indiana also collects a Motor Carrier Surcharge Tax on the same return. The surcharge tier depends on your fuel type and pulls from a different rate table than the base IFTA rate.
Illinois
Illinois processes the return manually after submission. The window from filing to "accepted" status runs 2 to 4 weeks. File two days before the deadline and you can still be flagged as late if the system hiccups.
Pennsylvania
Pennsylvania requires Oil Company Franchise Tax reconciliation on the IFTA filing for in-state purchases. The base IFTA report tools rarely calculate it correctly without manual review.
New York
New York stacks the Highway Use Tax (HUT) and the Fuel Use Tax (FUT) on top of the standard IFTA return. Three filings, three deadlines, one mistake reopens all three for audit.
New Jersey
New Jersey rejects returns submitted with rounding errors over $1. The portal does not round automatically, so a single bad decimal places the return in suspense.

IFTA self-file, questions answered.
Eight things drivers and fleet owners ask before they open a portal.
How many jurisdictions are in IFTA?+
There are 58 IFTA member jurisdictions: the 48 contiguous US states and 10 Canadian provinces. Alaska, Hawaii, Washington DC, and US territories are not IFTA members. A motor carrier operating a qualified vehicle in 2 or more IFTA jurisdictions must register and file quarterly.
When are the IFTA quarterly deadlines?+
Q1 is due April 30, Q2 is due July 31, Q3 is due October 31, and Q4 is due January 31. The deadlines are identical across every member jurisdiction. The portal you file through differs by your base jurisdiction.
What is the IFTA late filing penalty?+
The standard IFTA late penalty is the greater of $50 or 10% of the net tax due, plus interest at approximately 1% per month per jurisdiction (compounding). Several states layer additional penalties on top. New Jersey rejects returns with rounding errors over $1, and Texas flags accounts for closer review on the next quarter after a refile.
How long do I have to keep IFTA records?+
IFTA requires carriers to retain mileage records, fuel receipts, trip sheets, and GPS data for 4 years from the return due date. If you cannot produce them on audit, the auditor estimates against you using their own assumptions, which favors the jurisdiction.
How often does IFTA audit carriers?+
Every IFTA jurisdiction is required by the Articles of Agreement to audit at least 3% of the carriers based in that jurisdiction each year. That works out to roughly 1 in 30 carriers per year. Audit findings average several thousand dollars and can reopen prior quarters going back 3 to 5 years.
Can I file IFTA in multiple states?+
No. You file a single IFTA return with your base jurisdiction only. Your base jurisdiction redistributes the tax to the other states and provinces where you operated. You do not file separate returns in each state, but you do report miles and fuel by jurisdiction on the single return.
What records do I need to file IFTA?+
Total miles driven by jurisdiction (mileage logs, trip sheets, or GPS data), total taxable gallons of fuel purchased by jurisdiction (fuel receipts or fuel card statements), and your IFTA license and decal numbers. The mileage and the fuel must reconcile against each other within the auditors tolerance for your fleet MPG.
How much does it cost to file IFTA?+
Filing the return itself is free through every state portal. The cost is your time: gathering receipts, reconciling mileage by state, calculating tax per jurisdiction, and resolving any errors the portal flags. Outsourced services range from $25 per quarter for basic data entry to several hundred dollars per month for CPA filings. Argus IFTA is $127 per quarter for 1 to 3 trucks or $47 per truck per month for 4 or more.
You can absolutely do this yourself.
People do. People also miss a jurisdiction, get a notice, and pay 4x what filing would have cost.
