New application

The processing fee for an Idaho IFTA license is $10. IFTA decals are 60 cents for a set of two. Two decals are required for each vehicle. The application is available online, at any Idaho Port of Entry, at the Idaho Transportation Department (ITD) Commercial Vehicle Services, or at Idaho State Tax Commission offices. Your IFTA license and decals are valid from January through December of each year.

Renewal

You must renew your IFTA license and buy new decals annually. Current license holders can submit their renewal online or use the renewal form mailed to them.

IFTA licenses expire on December 31. You can order more decals at any time during the year. The processing fee for renewing or ordering additional decals is $5 plus 60 cents per decal set. If you haven’t filed all your IFTA returns or paid all your tax due (including any penalty or interest), you won’t be able to renew.

IFTA grace period (R655)

After you’ve renewed your IFTA license, you have two months to distribute copies of your IFTA licenses and decals to your IFTA fleet vehicles. You must display your old decals and licenses during this grace period.

Early display of IFTA credentials (R630)

You don’t have to wait until after December 31 each year to put your renewal decals on your IFTA fleet vehicles. If you renew your IFTA license and receive your license and decal sets for the next year, you can put them on your IFTA fleet vehicles as early as November.

Temporary permit

A 30-day IFTA temporary decal is available if you have a current Idaho IFTA license but don’t have enough decals to place a vehicle in service immediately. The temporary decal is valid for 30 days and is vehicle-specific. Each temporary decal costs $10. Temporary decals are available at the Tax Commission offices in Boise, Monday – Friday, from 8 a.m. to 4 p.m.

Bond

You’re not normally required to post a bond if you’re a new IFTA licensee. However, we may require a bond if you don’t file your returns on time, don’t pay the fuel taxes on time, or the results of an audit show you didn’t follow other IFTA requirements.

Account identification

If your company is a corporation, S corporation, LLC, or partnership, its IFTA license number is the federal Employer Identification Number (EIN) issued to it by the Internal Revenue Service. If you’re a sole proprietor, your IFTA number will be your EIN (if you’re required to have one), or your Social Security number. All Idaho IFTA license numbers begin with “ID” (Example: ID 987654321).

Highway use fee

If you travel in Kentucky, New Mexico, New York, and Oregon you must file that jurisdiction’s highway use fee report in addition to filing your Idaho IFTA return. You’ll have to report the distance traveled by your vehicles in these jurisdictions on both the IFTA return and the jurisdiction’s highway use fee report. The fee may be in addition to the IFTA fuel use tax.

Surcharge

Indiana, Kentucky, and Virginia are jurisdictions with a surcharge. When you travel in those states, you’ll pay an additional tax when you complete your IFTA return. You’ll report any distance for these states twice and compute the additional fuel use tax. There’s no credit for tax-paid fuel purchases when computing the surcharge tax.

IFTA Licenses Reporting

Form 3150 (Idaho’s IFTA report)

Before IFTA, you had to fill out a separate report for each jurisdiction where you traveled and send the report to that jurisdiction. Now, you use one form (Form 3150) to report for all the jurisdictions where you travel, and you send it to Idaho. You just complete a row for each jurisdiction, instead of completing up to 58 separate reports.

General information

Summarize your miles and gallons for the quarter by jurisdiction. You must file your Form 3150 even if you don’t have travel or owe tax. Use one of these methods to file your report:

  • Electronic filing. File securely using Taxpayer Access Point (TAP) at tax.idaho.gov/gototap.
    • TAP significantly improves reporting accuracy by calculating totals and entering the correct tax rate. First enter the total miles and gallons to get your miles per gallon (MPG). Then enter miles and tax-paid gallons by jurisdiction.
    • Pay on TAP. Avoid penalty and interest by filing your report early and scheduling the payment for the due date.
    • Make changes to your account or cancel your license.
    • Print copies and save reports.
  • Preprinted Form 3150. Complete the preprinted Form 3150 for each filing period. The Idaho State Tax Commission mails these to you.

Important Reminders

Keep records

See recordkeeping for information on records you must keep.

Filing a paper report

You must use Form 3150 for the filing period listed on that form. You can make copies of the blank one in case you make a mistake and need another copy. You can submit the copy if there aren’t changes to the scan line or bar code.

Sign the report

You must sign and date the form. Unsigned forms might result in penalty, interest or both.

Due date

Make sure to file your report and pay on time to avoid penalty and interest.

  • When filing on TAP, submit the report by 11:59 p.m. (MT) on the due date. You can submit your report early and schedule the payment for the due date.
  • When mailing, make sure the report is postmarked by the due date.

Most IFTA license holders must file a fuels tax report every calendar quarter. The reporting periods are:

QuarterDue dateForm sent
January – MarchApril 30March 31
April – JuneJuly 31June 30
July – SeptemberOctober 31September 30
October – DecemberJanuary 31December 31

Change of mailing address

Check the “Mailing Address Change” box on your IFTA report and provide the new address.

Cancel your IFTA license

Check the “Cancel License” box when you file your last report. Write the last day you’ll operate any IFTA-qualifying vehicles under the authority of your Idaho IFTA license.

Sections 1 and 2

Preprinted information on the IFTA report identifies you, your IFTA license, reporting period, and report due date. If you don’t get a report for a certain reporting period, file using your TAP account or request a copy from us. Using an IFTA report from a different reporting period might result in penalty, interest or both.

IFTA Licenses Guide

Interstate motor carriers buy tax-paid fuel in each jurisdiction they travel through. This tax is used to pay for the carriers’ use of the highways in these jurisdictions.

International Fuel Tax Agreement (IFTA)

The International Fuel Tax Agreement (IFTA) is an agreement among 58 jurisdictions – 48 U.S. states and 10 Canadian provinces. The agreement reduces paperwork and standardizes fuel use tax reporting.

For example:

  • All jurisdictions use the same definition for qualifying motor vehicles (R130.100.015).
  • A carrier selects one base jurisdiction to report all travel instead of filing a separate return for each jurisdiction the carrier travels in (R130.100.005).
  • A single fuel use tax license allows a carrier’s vehicles to travel in all IFTA jurisdictions (R150).
  • Only the base jurisdiction audits the carrier (R1310).

Throughout these pages, notes such as P1300 refer to portions of the IFTA Procedures Manual, and notes such as R1310 refer to the IFTA Articles of Agreement. Both the IFTA Procedures Manual and the IFTA Articles of Agreement can be found on the IFTA website.

Most U.S. states and Canadian provinces are members of IFTA. However:

  • In the U.S: Alaska, Hawaii, and the District of Columbia aren’t members.
  • In Canada: the Northwest, Yukon, and Nunavut territories aren’t members.

If you buy fuel that includes tax, but use it in a nontaxable way, you can get a refund.
