Rhode Island IFTA Filing Walkthrough: Taxpayer Portal

Rhode Island is one of the few places where an IFTA license costs nothing. The General Assembly dropped the $10 license and decal charges effective July 5, 2019, so a Rhode Island carrier pays only the fuel tax itself. The catch sits on the filing side: the application still goes in on paper, while the quarterly return has lived on the Division of Taxation's Taxpayer Portal since April 1, 2024. The sourced facts render on the Rhode Island IFTA page. This walkthrough puts them in the order you will work through them.

Who runs it, and where

The Rhode Island Division of Taxation runs IFTA through its Excise Tax Section, part of the Department of Revenue. Two channels matter:

• The Excise Tax Section takes applications and issues decals: One Capitol Hill, Providence, RI 02908; Tax.Excise@tax.ri.gov; (401) 574-8955; fax (401) 574-8914. Office hours run Monday to Friday, 8:30 a.m. to 3:30 p.m.
• The Taxpayer Portal at taxportal.ri.gov takes the quarterly returns and payments. The Taxpayer Portal Team answers questions and books in-person help at (401) 574-8484 or taxportal@tax.ri.gov.

Plates are a separate agency. The Division of Motor Vehicles runs apportioned registration from its IRP Office in Cranston, covered on the Rhode Island IRP registration page. Your IRP number goes on the IFTA application, so register plates first.

Step 1: confirm Rhode Island is your base jurisdiction

Per the Division's Compliance Manual (Rhode Island Division of Taxation, "International Fuel Tax Agreement Information and Compliance Manual," updated February 2025), Rhode Island can be your base jurisdiction when three things are true:

1. You keep operational control and records for your qualified vehicles in Rhode Island, or can make them available there.
2. Your qualified vehicles actually travel on Rhode Island roads.
3. You operate in at least one other IFTA jurisdiction.

A qualified motor vehicle has two axles and a gross or registered gross vehicle weight over 26,000 pounds (11,797 kg), or three or more axles at any weight, or runs in a combination over 26,000 pounds. Recreational vehicles are excluded.

Leases follow a simple default. The carrier operating the vehicle pays the fuel tax unless the lease says otherwise, and an independent contractor on a trip lease of 29 days or less reports its own fuel tax.

Step 2: mail the IFTA-APP

Here is where Rhode Island differs from portal-first states. The license application, Form IFTA-APP, comes from the Division's Sales and Excise Forms page and goes in by mail to the Rhode Island Division of Taxation, Excise Tax Section, One Capitol Hill, Providence, RI 02908-5800.

Have this ready before you start the form:

• Legal and business names, FEIN, and physical and mailing addresses
• USDOT number and IRP registration number
• The date your IFTA operation in Rhode Island begins, and any prior IFTA jurisdiction
• A contact person for quarterly reporting and your type of business
• Principal officers or owners, with Social Security numbers and residence addresses
• Fuel types, and every jurisdiction where you operate or keep bulk fuel

The Division refuses credentials if your IFTA account is delinquent or your license is suspended or revoked in another member jurisdiction. Once approved, you get a 13-character account number: "RI", usually your FEIN, and a two-character suffix, usually "00". You will use that number on every return.

Step 3: put the free license and decals to work

The license and decals cost nothing. R.I. Gen. Laws section 31-36.1-3(a) says there shall be no fee for the motor carrier fuel use license (State of Rhode Island General Assembly, "Motor carrier license and identification - Temporary licenses"), and the Compliance Manual extends that to the application, reinstatement, renewal and decals.

What you do owe is correct display:

• The license runs January 1 through December 31. Carry the license or a photocopy in the cab of each qualified vehicle. You get one extra copy for your office records.
• The decals come two per qualified vehicle, one on the outside of each side of the cab. Section 31-36.1-3(a) requires the year's decals on or before March 1.
• Extra decals come from the Excise Tax Section on an Additional Decal Requisition form. Keep unused decals for four years.

A truck running without the license or with decals missing can be made to buy a trip permit, be cited, or both.

Step 4: weigh the 10-day temporary license

A carrier that qualifies but does not join IFTA has another route into Rhode Island. Section 31-36.1-3(c) lets an unlicensed carrier get a temporary license for one qualified vehicle for up to 10 days, also with no fee. The Division's pages do not publish a form or ordering method for it, so call the Excise Tax Section before the trip. The Compliance Manual reserves trip-by-trip permits for occasional travel outside your normal pattern, and you would still need trip permits in every other member jurisdiction you enter. The details are on the Rhode Island trip and fuel permits page. With a free annual license available, the temporary route makes sense only for a truck that almost never crosses the line.

Step 5: file the RI-IFTA-100 on the Taxpayer Portal

Beginning April 1, 2024, the Division expects all IFTA taxpayers to file and pay the quarterly Form RI-IFTA-100, Rhode Island Fuel Use Tax return, on the Taxpayer Portal. The electronic filing mandate backs that up: since tax periods beginning January 1, 2023, a business with combined annual Rhode Island tax liability of $5,000 or more, or annual gross income over $100,000, can be penalized for not filing through the portal.

Returns are due the last day of the month after each quarter:

File even in a quarter with no operation or fuel purchases. A due date on a Saturday, Sunday or legal holiday moves to the next business day, and any tax due is paid with the return.

Two form rules trip up first-time filers:

1. Round up. Mile and gallon fields take whole numbers, rounded up.
2. Surcharge jurisdictions get two lines. A jurisdiction with a surcharge carries a second rate code line on the schedule.

The rates are national. Rhode Island diesel this quarter is $0.4000provisionalIFTA Fuel Tax Rate Matrix, 4th Quarter 2026 (provisional) (International Fuel Tax Association, Inc. (IFTA, Inc.))Verified Oct 4, 2026 per gallon in the national matrix. Read every jurisdiction you ran in off the IFTA rates by state table, run your miles and gallons through the IFTA calculator, and check your records against the national how to file IFTA guide.

The portal also handles prior periods and amendments for the last eight quarters. That window lines up with the credit rule: a credit you do not use within eight quarters expires.

Step 6: price a late return before you skip one

The Compliance Manual sets the late-filing penalty at the greater of $50 or 10 percent of the net tax due to all member jurisdictions. Interest runs at two percentage points above the IRC section 6621(a)(2) underpayment rate, adjusted each January 1 and accrued monthly at one-twelfth of the annual rate. A quiet quarter with nothing owed can still cost $50 if the return never goes in.

Missed returns escalate from there:

• Bond. The Division can require a surety bond, cash bond or other obligation it accepts for just cause, such as late returns, unpaid tax or audit problems. A licensee under bond pays by certified check.
• Suspension or revocation. Failing to file, failing to pay, failing to pay or protest an audit assessment in time, or failing to keep records can cost you the license, and every member jurisdiction is notified. Reinstatement follows filing all returns and paying all liabilities.
• Appeal. A written hearing request is due within 30 days of the notice. Miss it and the finding is final.

Step 7: keep records that survive an audit

Records decide what an audit charges you. If yours are inadequate, or you produce none after a written demand, the Division adjusts your fleet to 4.00 miles per gallon (1.70 km per liter) or cuts your reported MPG by 20 percent. Either way, more taxable gallons land on the bill.

Keep records for four years from the return's due date or filing date, whichever is later. Distance records need trip dates, origin and destination, routes, odometer or ECM readings, trip and per-jurisdiction miles, and the unit number. If you use GPS, keep the original location data too.

Renewing each year

The license renews every calendar year. The Division's IFTA page (Rhode Island Division of Taxation, "International Fuel Tax Agreement (IFTA)") says renewal applications are due by December 1 for the year starting January 1. The fastest route is the Taxpayer Portal. The Division also mails Form IFTA-REN to every account with a current license. It lists the plate number, state of registration and VIN for each vehicle, and you get a decal for each vehicle listed.

One wrinkle in the law: section 31-36.1-3(a) says the license remains valid until surrendered or revoked, while the Division's manual and IFTA page treat it as renewable each calendar year. Carriers follow the Division's annual renewal.

Closing the account

To stop, file Form RI-2625, Account Cancellation Form/Permit Final Return, with the current year's decals or a written request, and return the original license and any unused decals to the Excise Tax Section. A final audit may follow, and the four-year record clock runs from the final return's due date.
