Austria’s Auditor Warns Fuel-Tax Plan Leaves €62 Million Uncovered

Austria’s Court of Audit warned on 6 November 2026 that a proposed fuel-tax measure would cover only part of the revenue shortfall in a wider tax bill, while the government’s estimates leave out some fiscal and climate costs.

In its newly published opinion on a Finance Ministry draft regulation, the Rechnungshof said projected additional mineral-oil tax receipts of **€150 million over 2026–2030** fall short of the **€212 million in revenue reductions** shown for the associated 2026 Tax Amendment Act. The €62 million difference is a comparison of **forecasts**, not money already lost or a final budget deficit. The auditor said the incomplete offset creates a risk of higher federal borrowing.

The proposal follows a 28 May 2026 ruling by Austria’s Administrative Court concerning input-VAT refunds on fuel bought by Turkish businesses. Under the draft regulation, eligible Turkish businesses would be able to reclaim input VAT on fuel purchases, while different treatment would continue for businesses from other non-EU states. The ministry anticipates that changed refuelling behaviour would shift fuel purchases into Austria and raise mineral-oil tax receipts.

The auditor said the forecast assumes roughly **75 million additional litres of fuel purchased in Austria annually**, generating about **€30 million per year** in mineral-oil tax revenue. It called the calculation understandable but said the basis for the 75-million-litre behavioural assumption was not disclosed. It also challenged the expectation of a full year’s extra revenue in 2026, since businesses would need time to change where they refuel.

The opinion identified a second omission: the fiscal assessment did not quantify reduced VAT receipts resulting from the newly permitted refunds to Turkish firms. Nor did it include potential costs of emissions certificates if Austria misses its EU climate targets. The assessment projects up to **200,000 tonnes of additional CO₂-equivalent emissions** from the anticipated increase in fuel purchases. That is a projection of emissions linked to the refuelling assumption, not a measured increase already observed.

The Court of Audit also objected to the consultation period. It said the Finance Ministry allowed only **eight working days** without explaining why, although the normal benchmark is at least six weeks. The auditor said silence from a consulted institution could not reasonably be interpreted as absence of objections under such a shortened timetable.

The ministry’s policy is still a proposal, not an enacted measure or an established tax-revenue outcome. The official Austrian Parliament record identifies the related **Abgabenänderungsgesetz 2026 (148/ME)** as a ministerial draft received on 22 October, with the consultation period ending 3 November and the file forwarded to the Finance Ministry on 4 November. Its stated objectives include simplifying tax administration, easing burdens on businesses and employees, and aligning Austrian law with European and higher-court requirements. Those policy aims are distinct from the auditor’s challenge to the fiscal estimates.

The next material checks are the Finance Ministry’s response to the 6 November opinion, any revised financial-impact assessment, the final ordinance and tax-bill texts, and whether projected fuel sales, VAT refunds and emissions are measured after implementation. Neither the draft nor the audit opinion establishes wrongdoing by officials or companies.
