IFTA Tax Rates in Rhode Island (2026)

Key numbers at a glance

IFTA tax rates in Rhode Island

Rhode Island's motor fuel tax is $0.40 per gallon on gasoline and diesel alike, effective July 1, 2025, per the Rhode Island Division of Taxation's motor fuel tax page, and the Q4 2026 IFTA Inc. matrix carries the same 40.0-cent figures. Comparison tables that fold in fee components show a combined figure near 41.1 cents — the Tax Foundation's July 2026 table lists $0.4112 — but the IFTA number to file is 40 cents. Rates below are as of Q4 2026 — confirm the current official IFTA matrix before filing.

The rate mechanics matter for planning: Rhode Island indexes its fuel tax, and it stepped from 38 cents to the 40-cent base under the FY2026 budget effective July 1, 2025. That means the next possible move is a July 1 adjustment — mid-calendar-year, and therefore mid-Q3 for IFTA purposes. A one-cent move on a small state line is pocket change per trip, but it is also the kind of change that makes copied-forward spreadsheets quietly wrong.

Regionally, Rhode Island sits in the middle of a compressed band: 38.05-cent diesel in New York, 40 cents flat in RI, 41 cents in North Carolina, then the cliff edges — 47-cent diesel in Ohio and 74.1-cent diesel in Pennsylvania. On gasoline, RI's 40 cents actually edges above New York's 39.8 cents.

How Rhode Island IFTA affects your filings

Rhode Island's contribution to any single quarterly return is small by construction. The state spans a short stretch of I-95; at 6.5 MPG, 100 Rhode Island miles burns about 15.4 gallons, which is roughly $6.15 at 40 cents. Run that corridor weekly and it becomes $80 or so a quarter — real money, but never the line that decides whether the return shows a balance due or a refund. The lines that decide that are usually Pennsylvania diesel at 74.1 cents and the big-mileage states around it.

That is exactly why Rhode Island gets missed. Carriers skip fueling there entirely (sensible — there is little arbitrage at 40 cents when Pennsylvania credits 74.1), then fail to record the miles precisely because the tax is small. But distance records are audited as a whole: if your ELD shows a Providence delivery and your IFTA return shows zero Rhode Island miles, that mismatch is an audit finding regardless of the dollars. The professional habit is to log every state line accurately and let the math be small.

For fuel strategy on New England lanes, the playbook stays the same one the IFTA calculator runs everywhere: size Rhode Island and other mid-rate stops to the miles you will burn in the region, position the heavy fills where credit is richest (Pennsylvania, when pre-tax prices are comparable), and never let a cheap pump in a low-tax state fund miles in a 40-cent-plus state without doing the subtraction first. Re-check the matrix every quarter for the July indexing, keep receipts matched to miles, and make sure your fuel surcharge covers the Northeast's tax stack rather than the national average. All 48 jurisdictions sit side by side on the IFTA rates by state hub.
