IFTA Tax Reporting Requirements
Once you are licensed under the IFTA Program, DMV will mail a tax return form to you each quarter. You must file your quarterly returns by:
- April 30
- July 31
- October 31
- January 31
NOTE: If the above dates fall on a weekend or legal holiday, the due date is the next business day.
As an IFTA carrier, you will receive a quarterly tax return form for reporting operations in all IFTA jurisdictions. You must file whether you receive the return or not.
Late Filing Penalty
If you do not file your tax returns on time, you will be subject to a late fee of $50 or 10 percent of the tax due, whichever is greater. Interest will also be assessed. The penalty and interest will be assessed if:
- your return is not received at DMV or postmarked by the deadline; OR
- you do not remit the total tax due.
For your convenience, you can electronically file your quarterly tax filings using webCAT. All you have to do is enter your miles and fuel purchases for a particular quarter and webCAT will complete the calculations for you!
