Guatemala’s Fuel Tax Cut Sits on the President’s Desk: What Expats Need to Know

Guatemala spent September watching lorries block its highways over the price of diesel. Congress has now handed the president a law that strips two taxes from fuel until the end of the year. He can sign it or send it back — and either choice lands in a budget year that was already running ahead on collections.

What Congress Passed

Decree 22-2026 removes two taxes from regular petrol, premium petrol, diesel and gas oil. The first is the IDP, a per-gallon levy on the distribution of petroleum products. The second is value-added tax, charged on both the import and the sale of those fuels. The exemption runs to 31 December 2026, and normal rates return on 1 January 2027.

Deputies altered the day’s agenda on 22 September to take up initiative 6852 and passed it in one debate, 149 votes in favour, none against, eleven absent, the official gazette reported. The window for objections closed at 4:30 p.m. on Friday 25 September without any being filed, and the decree went to the president on Saturday 26 September.

The Money at Stake

The finance ministry puts the revenue loss at Q3.32 billion (about US$434 million). That splits into Q1.33 billion (about US$174 million) of fuel distribution tax and Q1.99 billion (about US$260 million) of forgone value-added tax.

At the pump, the ministry estimates savings of Q9.41 (about US$1.23) a gallon on premium petrol, Q9.10 (about US$1.19) on regular petrol and Q6.34 (about US$0.83) on diesel. Self-service prices on 23 September stood at Q43.29 (about US$5.67) for regular, Q45.29 (about US$5.93) for premium and Q49.39 (about US$6.46) for diesel. If the decree is signed and the savings pass through fully, diesel would fall to roughly Q43 (about US$5.63) — still far above the Q39 cap the government floated earlier this month.

Two Decrees, One Decision

The tax cut is not the only fuel measure in play. On 7 September the government floated a separate bill capping diesel at Q39 a gallon through the end of 2026; Congress approved a cap decree on 8 September, but procedural objections have kept it from taking effect. The president now weighs the tax cut against that stalled cap: the first costs the treasury about US$434 million in revenue; the second shifts the burden to fuel importers and retailers.

Arévalo, a centre-left academic who took office in January 2024, governs with a small bench in a Congress dominated by other parties — which makes the unanimous 149-vote passage notable, and also means the votes exist to override objections or move on without him.

What Is Not Yet Known

Whether the president signs, vetoes or returns the decree with observations — and when. If signed, how quickly importers and stations pass the tax cut through to pump prices; the ministry’s savings figures are estimates, not guarantees. Whether the Q39 diesel cap revives as an alternative. And whether the relief reaches bus fares and market prices, which is where lower-income households would actually feel it — the finance committee’s own chairman notes that half the direct relief flows to the richest tenth.

What This Means for Expats and Nomads

If you drive in Guatemala, a signed decree means roughly US$0.83 off each gallon of diesel and about US$1.19 off regular petrol from the date it enters into force, against 23 September prices. If you live on buses and markets, as most residents, foreign and local, do, the effect arrives indirectly and slowly, through fares and food. September’s blockades showed how quickly fuel prices become road closures here: seventeen highways were blocked and crossings on the Mexican border shut before the protests were cleared. Watch the president’s decision before planning long overland trips, and keep the tank topped up in the meantime.
