IFTA is the quarterly tax that’s unique to trucking and transportation companies. If you operate commercial motor vehicles across state lines, you’re required to file IFTA returns and pay any fuel tax owed. The returns are due April 30, July 31, October 31, and January 31. You’ll report the miles driven in each state and the fuel purchased in each state, and the system redistributes tax to states where you drove but didn’t buy fuel.

Federal estimated income taxes apply if you expect to owe more than $1,000 when you file your return. Most trucking company owners and owner-operators fall into this category. These payments are due April 15, June 15, September 15, and January 15. The IRS expects you to pay as you earn, not wait until tax time with a large bill.

Arkansas requires estimated state income tax payments following roughly the same schedule as federal. The amounts are smaller but missing them still results in penalties and interest. If you operate in multiple states, you may have estimated tax obligations in those states as well depending on how much income you earn there.

Payroll taxes come into play if you have employees. Form 941 is due quarterly for federal withholding and the employer’s share of Social Security and Medicare taxes. Arkansas state withholding follows a similar schedule. You also have quarterly unemployment tax obligations at both the federal and state level.

The challenge for most trucking companies is keeping up with the tracking that makes these filings accurate. IFTA requires detailed fuel receipts and mileage logs by state. Estimated taxes require knowing your actual profit, not just guessing. Payroll taxes require reconciling what you withheld and deposited throughout the quarter.

Falling behind on any of these creates problems that compound. IFTA penalties add up quickly and can affect your operating authority. Federal tax penalties include failure-to-pay and failure-to-file charges that stack on top of interest. Getting behind on payroll taxes is especially serious because the IRS considers that trust fund money that belongs to employees.

Working with a bookkeeper near Fayetteville who understands trucking means someone is watching these deadlines and making sure the numbers are ready before the due date. Quarterly obligations are manageable when you track throughout the quarter instead of scrambling at the end.
