A new Italian think tank study warns that policymakers may soon need to tackle a problem that sounds like science fiction: how to tax wealth generated hundreds of kilometers above Earth. The Eurispes Laboratory on Fiscal and Tax Policy, coordinated by Giovambattista Palumbo, cautions that without urgent international legislation, orbital space risks becoming the next offshore haven—a vacuum where multinational corporations extract resources, run server farms, and sell satellite services with zero tax accountability.
Why This Matters
• No legal framework exists to tax space mining, satellite telecoms, or orbital tourism—activities already generating revenue in 2026.
• Italian and European tax authorities lack jurisdiction over economic activity conducted in orbit, creating a potential fiscal blind spot.
• Major space operators like SpaceX, Eutelsat, and Rocket Lab currently navigate a fiscal "terra di nessuno," paying taxes only on Earth-based operations while orbital assets remain untouchable.
• The Outer Space Treaty of 1967 forbids national sovereignty over celestial bodies but says nothing about taxing commercial profits extracted from them.
The Fiscal Blind Spot Above Our Heads
The core dilemma is not whether to tax space—it's how to redistribute the wealth being generated beyond any nation's borders. Current tax systems are built on 19th-century concepts: physical presence, territorial jurisdiction, and permanent establishment. None of these apply 400 kilometers up, where the International Space Station orbits and where companies now operate commercial platforms.
Italy's tax code, like those of most countries, defines taxable income by geographic source or corporate residence. But what happens when a Luxembourg-registered company mines platinum from an asteroid using a robot launched from French Guiana, sells the metal to a Japanese buyer, and stores the transaction data on a server physically located on the Moon? Under the 1967 UN Outer Space Treaty, no state can claim sovereignty over celestial bodies—meaning no state can unilaterally impose territorial taxes there.
The Eurispes study identifies this as a structural threat: without coordinated global rules, space becomes a lawful tax shelter, accessible only to capital-rich nations and their corporate champions. Smaller economies, including Italy, risk being locked out of the wealth distribution entirely.
What's Already Happening in Orbit
The economic activity in question is no longer hypothetical. As of mid-2026, several categories of space commerce are operational:
Satellite constellations like SpaceX's Starlink and Eutelsat OneWeb provide broadband internet from low Earth orbit, generating subscription revenue that flows back to Earth. Eutelsat OneWeb alone operates over 630 satellites, while French parent Eutelsat manages additional assets in geostationary orbit. These companies are taxed on their terrestrial headquarters and ground operations, but the orbital infrastructure itself sits in a legal gray zone.
Space tourism is ramping up through operators like Blue Origin and SpaceX, with ticket prices reaching hundreds of thousands of euros per seat. The United States has floated a proposal for a 10% ticket surcharge to account for the high per-capita emissions of commercial spaceflights, but no international consensus exists on how to tax the operators or the experience itself.
Resource extraction—the most contentious frontier—remains in the planning stage, but legal frameworks are already being contested. The U.S. has passed domestic legislation treating space-sourced income as American-source revenue for tax purposes, a unilateral move that other nations view as incompatible with the Outer Space Treaty's non-appropriation clause.
The Legal Vacuum and Its Consequences
Italy, as an EU member and G7 economy, participates in the OECD's ongoing negotiations on Pillar One and Pillar Two tax reforms, which aim to establish a 15% global minimum corporate tax rate and reallocate profits from multinationals to market jurisdictions. But even these ambitious frameworks are designed for terrestrial businesses. They fail to address how profits from orbital operations should be attributed, let alone how a company with no physical presence in any country should be taxed.
The Outer Space Treaty offers no guidance on fiscal matters. It establishes that space is the "province of all mankind" and that states retain jurisdiction over objects they launch. But it does not define what happens when a private entity—registered in a low-tax jurisdiction—launches a mining rig to an asteroid and extracts rare earth metals. Who collects the royalties? Who enforces compliance?
The Moon Agreement of 1979, which attempted to designate celestial resources as "common heritage of humanity," has been ratified by only a handful of states—none of them major space powers. In its place, the Artemis Accords, led by the United States, explicitly endorse private resource extraction, further fragmenting the legal landscape.
What This Could Mean for Italian Taxpayers
As orbital commerce grows untaxed, the financial burden of funding public services—schools, healthcare, infrastructure—falls increasingly on terrestrial taxpayers. Italian residents and businesses already face significant tax burdens; without a framework to tax space-generated wealth, that burden could intensify while multinational corporations profit in orbit. Additionally, if Italy lacks a seat at the table in negotiations over space taxation, the country risks being excluded from revenue-sharing arrangements that wealthier nations secure for themselves.
What a Global Space Tax Law Could Look Like
The Eurispes study proposes several mechanisms to close the fiscal gap:
• An international space authority with tax collection powers, operating under UN or OECD auspices, to administer licenses and levy fees on orbital economic activity.
• Royalties on space mining, similar to how nations tax seabed mining under the International Seabed Authority, ensuring that resource extraction benefits all nations, not just those with launch capacity.
• An "Orbit Tax" levied on commercial satellites and orbital platforms, with revenues earmarked for cleaning up space debris—a growing environmental hazard that threatens all orbital infrastructure.
• A Space Border Tax applied when goods, data, or resources produced in space are "reimported" to Earth, capturing value at the point of terrestrial entry.
These proposals mirror the logic behind the EU's digital services tax, which taxes revenue generated within a jurisdiction even if the company has no physical office there. The difference is scale and enforceability: space commerce operates beyond the reach of any single regulator.
What This Means for Italy and Europe
Italy's fiscal authorities have been aggressive in pursuing digital tax compliance, expanding the country's web tax in 2026 to cover all digital operators, not just multinationals. But space commerce could dwarf digital revenue within a decade, and Italy currently has no legal tools to claim a share of that wealth.
For Italian policymakers, the risk is twofold. First, domestic aerospace companies—such as those involved in satellite manufacturing or launch services—could face competitive disadvantages if foreign rivals operate tax-free in orbit. Second, Italy's contribution to the EU budget and its fiscal stability depend on maintaining a broad tax base; if orbital commerce grows unchecked, it siphons wealth away from taxable terrestrial economies.
The European Commission has acknowledged the urgency of fair taxation in the digital economy, and the EU Space Act under discussion in 2026 includes provisions for authorization fees and platform tariffs for satellite operators. But these are regulatory costs, not taxes, and they do nothing to capture the value of resource extraction or tourism.
The U.S. and China Are Already Moving
While Europe debates, the United States has enacted domestic legislation treating space income as American-source revenue, giving its tax authorities a claim on profits from U.S.-launched missions. SpaceX, which has benefited from billions in federal contracts and state-level tax breaks in Texas, has also used aggressive accounting strategies—including $1.9B in "uncertain tax benefits"—to minimize its U.S. tax burden.
China, which has rapidly expanded its space program, operates under a state-controlled model that blurs the line between public and private sectors, making tax transparency opaque.
The absence of a multilateral framework means that fiscal competition is already extending into orbit, with nations racing to attract space operators through favorable tax treatment—exactly the dynamic that Eurispes warns against.
A Call for Global Coordination
The study's central argument is philosophical as much as practical: the wealth of space should belong to humanity, not to a handful of corporations or states. But without enforceable rules, the principle remains aspirational.
Current international tax negotiations—such as the UN Framework Convention on International Tax Cooperation, expected to conclude by 2027—could provide a starting point. But space taxation is not yet on the formal agenda, and progress will require political will from the G7, OECD, and UN member states.
For Italy, the message is clear: engage now or risk exclusion later. The fiscal frontier is no longer just offshore islands or digital platforms. It is, quite literally, out of this world.
The Bottom Line
Space is already an economic zone, but it remains a fiscal no-man's-land. Without a global framework to coordinate taxation, Italy and other mid-tier economies risk a future where orbital wealth flows untaxed to a privileged few, deepening inequality on Earth. The tools to address this—international royalties, orbit fees, border taxes—exist in theory. What's missing is the political consensus to deploy them.
