Tax credits have become one of the main tools governments use to steer investment toward industries they consider strategically important. Clean energy, battery production, semiconductors and critical minerals are costly to build, take years to become profitable and compete across borders. A refundable credit can lower the cost of a project even when a company owes little or no tax. That makes it more immediate than a conventional tax break—and more visible to investors comparing locations.
The policy appeal is straightforward: governments can support a defined activity, such as building a factory or installing clean power equipment, without taking direct ownership of the project. But the public cost can be substantial, and the benefits may flow mainly to companies that would have invested anyway. The central test is whether incentives create additional economic activity that would otherwise have gone elsewhere or not happened at all.
Why refundability matters
A non-refundable tax credit reduces a company’s tax bill, but its value depends on the company having enough tax to pay. A new factory, early-stage clean technology firm or project with large start-up losses may not be able to use the full credit for years. Refundability changes the timing: if a project meets the rules, the government can pay out the credit even when the claimant has little tax liability.
That can make a credit more useful when investment decisions are being made. Companies weigh the cost of construction, financing, labour, energy and regulatory uncertainty; the promise of a benefit many years away may carry less value than cash available during the build. Refundability can also make support accessible to newer firms and projects that have not yet turned a profit.
Governments use other mechanisms to improve a credit’s value. The United States allows eligible entities to receive payment for certain credits or sell some credits to unrelated buyers. Canada’s clean economy investment tax credits include refundable support, with some clean technology investments eligible for a credit of up to 30%. In the European Union, member states can authorize certain forms of state aid for clean energy, industrial decarbonization and clean technology manufacturing, subject to common rules.
Three systems, similar aims
Canada’s approach uses targeted investment credits to reduce the cost of eligible equipment and facilities in areas such as clean technology, manufacturing and electricity. Refundability gives the support value to projects before they generate substantial taxable income. Some credits also tie full rates to conditions such as prevailing wages and apprenticeship requirements, linking the incentive to how projects are built as well as what they produce.
The U.S. model has relied on a mix of investment and production incentives, alongside ways for eligible entities to monetize certain credits. Transferability can bring private buyers into the financing chain; direct payment can make particular credits usable by entities that would not otherwise have enough tax liability. These arrangements broaden access, though they add paperwork, eligibility checks and transaction costs.
The EU faces a different structural challenge: member states have different fiscal capacity. Its common state-aid framework is intended to let governments support clean industrial investment while limiting distortions inside the single market. That still leaves room for competition among countries, and it can favour member states with deeper budgets. A shared rulebook can constrain the contest; it cannot make every government equally able to participate.
The cost and fairness questions
A tax credit is spending delivered through the tax system. Its cost may be less visible than a grant, but it still means lower public revenue or a direct payment. If the project would have gone ahead without support, the credit becomes a transfer to the investor rather than a decisive reason for building. Governments can also end up paying more than expected when uptake exceeds forecasts or when companies qualify for multiple forms of support.
There is a distributional question as well. Large companies with specialized tax and legal teams may be better placed to navigate complicated rules and negotiate project terms. Smaller firms may face higher administrative costs relative to the value of the incentive. Credits tied to capital spending can also benefit asset-heavy industries more readily than sectors whose value comes from skilled work, services or intellectual property.
The answer is not to assume every credit fails. It is to require a clear case for public support: what market problem is being addressed, what investment is genuinely incremental, what public benefits are expected, and what happens when targets are missed? Transparent reporting, project-level conditions, caps and expiry dates can help make the cost visible and give governments a chance to revise programs.
International tax rules add another layer
For large multinational groups within the scope of the OECD’s global minimum tax, the form of an incentive can affect how it is treated in effective-tax calculations. Under the agreed rules, a qualified refundable tax credit—generally one payable in cash or cash equivalent within four years—may be treated differently from a credit that reduces covered taxes. That distinction can affect how domestic incentives interact with minimum-tax rules, so governments must consider international tax treatment alongside the headline credit rate.
The framework does not eliminate competition for investment. It changes some of the calculations and increases the importance of how incentives are designed and documented. Governments still need to consider trade rules, domestic budget limits and the risk that a subsidy shifts production from one jurisdiction to another without creating much additional global investment.
MarketMind Insight
Refundable credits can make industrial policy faster and more targeted by reducing the upfront cost of building in priority sectors. Their success depends on whether they change real investment decisions and deliver benefits beyond the recipient company. The strongest programs set clear conditions, publish their fiscal cost and measure outcomes against a credible baseline.
The competition for factories and clean technology capacity is unlikely to disappear. But a larger credit is not automatically a better offer. Governments must weigh the investment attracted against the revenue committed, the fairness of who qualifies and whether the project leaves behind durable skills, suppliers and infrastructure.
