VAT Exemption and Refund in Nuclear Power Plant Investments:

Scope and Purpose of the VAT Regulation in Nuclear Energy Investments

Establishing energy supply security and integrating the national energy infrastructure with international standards are among the fundamental building blocks of macroeconomic objectives. To alleviate the financial burden of capital-intensive strategic projects, legislators frequently introduce revisions to tax legislation. Notably, the VAT regulation within the recently enacted omnibus bill represents a significant milestone within the framework of tax exemptions for energy investments aimed at reducing foreign dependency. In fields requiring high technology, lengthy construction periods, and multi-billion-dollar budgets—such as nuclear energy—the financing costs generated by value-added tax directly impact project feasibility. Driven by this reality, the VAT exemption for nuclear power plants mechanism was implemented to safeguard investors’ cash flow and expedite procurement processes.

What are Article 9 of the Omnibus Bill and Provisional Article 47 of the VAT Law?

As part of a series of legislative arrangements widely known to the public as the “Omnibus Bill,” which contains comprehensive amendments to tax legislation, Provisional Article 47 has been incorporated into the Value Added Tax Law No. 3065. Enacted via Article 9 of the relevant omnibus bill, this new provision establishes a narrow, specific exemption scope exclusive to nuclear energy investments. Fundamentally, Provisional Article 47 of the VAT Law exempts from taxation the deliveries of goods and performance of services required during the construction, modernization, and commissioning phases of nuclear power plants.

This exemption is not confined merely to the direct construction of the power plant; it also encompasses complementary services such as engineering, consultancy, logistics, and assembly carried out within the project’s scope. The most striking aspect of this regulation is its classification as a “full exemption.” In this context, suppliers and contractors executing transactions within the scope of the exemption possess the right to deduct the VAT they have incurred due to these deliveries. Any amounts that cannot be recovered through deduction are eligible for a refund.

Effective Date and Validity Period of the Regulation

Nuclear power plant projects are subject to complex engineering schedules that can span decades from the planning phase to commercial operation. Taking this long-term structure into account, the legislator determined the validity period of Provisional Article 47 of the VAT Law from a highly broad perspective. According to the statutory text, the exemption remains applicable until a future date stipulated in the legislation.

Such prolonged validity serves to protect the investor against potential fluctuations in the global supply chain, possible delays in construction phases, and scenarios where different reactor units of the project are commissioned progressively. Consequently, it makes nuclear energy projects in Turkey highly attractive for international investors and consortiums. Beginning from the effective date, the tax administration and customs authority establish the technological infrastructure to integrate all their practices in alignment with this long-term projection.

Conditions for VAT Exemption in Machinery and Equipment Deliveries

Constituting the backbone of industrial investments, machinery and equipment purchases represent one of the largest items in the total investment amount. Considering the costs of specific hardware utilized in nuclear energy projects—such as reactor pressure vessels, steam generators, turbine systems, and heavy industrial cranes—the application of a VAT exemption on machinery and equipment deliveries is of vital importance. However, it must be emphasized that this exemption is not an absolute, unconditional right; rather, it remains subject to strict certification and auditing mechanisms.

Purchases and Import Procedures under the Investment Incentive Certificate

In the application of Provisional Article 47, the customs VAT exemption does not activate directly and automatically for nuclear investments. The legal basis for this process is the Investment Incentive Certificate (IIC) issued by the Ministry of Industry and Technology. As a rule, to operationalize the investment incentive certificate VAT exemption mechanism, the goods to be imported or the machinery and equipment to be procured domestically must be explicitly listed in the approved annexes of the said certificate.

It is a widely accepted fact that during the import phase, customs brokers and foreign trade operations teams must ensure that the Customs Tariff Statistics Position (HS Code / GTİP) of the imported goods matches the HS Code in the IIC annex. Conducted electronically via the Single Window System, this matching process is meticulously verified by customs administrations. Goods that are not included in the certificate, exceed the specified quantity, or deviate from the approved list in terms of technical specifications are generally considered ineligible for the exemption, and value-added tax may be collected within the framework of general provisions. This situation once again highlights the critical role of preliminary reviews and regulatory compliance efforts undertaken by customs brokerage firms during import procedures.

Rights and Responsibilities of Pre-license and License Holder Taxpayers

The regulation grants the right to exemption directly to pre-license or license holder taxpayers, who are the actual owners of the project. Companies that have obtained the necessary permits from the Nuclear Regulatory Authority (NDK) or other relevant authorities are the primary addressees of this exemption. Nevertheless, exercising this right entails substantial legal responsibilities.

It can be stated that the administration fundamentally expects the machinery, equipment, and services procured under the exemption to be utilized within the framework of the construction and operation of the nuclear power plant. Should the procured goods be used for purposes other than the exemption, sold to third parties, leased, or transferred, it must be borne in mind that the unpaid tax may be collected from the buyer, along with potential tax penalties and interest. Therefore, project execution firms must structure their inventory management and fixture tracking in a transparent, traceable manner that is consistently ready for audit.

Refund Process of Non-Deductible VAT and Application Principles

In projects that span many years and involve massive costs, such as nuclear power plant construction, the exemption provided solely on machinery and equipment imports may not suffice. Due to site mobilization, materials procured from local suppliers, labor services, and general expenses, a substantial VAT burden accumulates on the taxpayer. To prevent this burden from depleting working capital, the nuclear energy VAT refund procedure was integrated into the law.

Details of the Refund for VAT Unrecoverable Through Deduction

The “deduction mechanism,” which serves as the foundational philosophy of the VAT system, relies on the taxpayer deducting the VAT they have incurred from the VAT they have collected. However, since companies in the investment period have not yet commenced production and sales, they hold no collected VAT. To resolve this structural issue, Provisional Article 47 adopts the “full exemption” model. According to this model, subcontractors delivering goods or performing services for the license-holding company under the scope of the exemption include the tax they incur from these transactions in their deduction accounts. Amounts that cannot be compensated through deduction by year-end or the relevant taxation period may be refunded in cash or on account, in accordance with the procedures determined by the Ministry of Finance.

This refund mechanism lowers the financing costs of subcontractors and material providers within the supply chain. The elimination of the tax burden at every link in the chain ultimately reflects positively on the total cost parameters of the main project.

Application Procedures and Required Documents

VAT refund processes are among the areas where the tax administration is most sensitive and enforces the strictest auditing. It is well established that for a refund request to be processed, standard forms must typically be filled out completely in an electronic environment (via systems designated by the administration). The process is finalized through a Sworn-in Certified Public Accountant (YMM) VAT Refund Certification Report or a tax inspection report.

The essential documents that must be submitted to the administration during the application phase are as follows: * Refund request petition, * Copy of the investment incentive certificate and the approved machinery and equipment list, * List of incurred VAT, * List of deductible VAT, * List of sales invoices (or a breakdown of invoices issued under the exemption), * Copies of the Customs Declaration for import transactions, * Customs receipts and tax collection receipts pertaining to the relevant periods.

In particular, the accuracy of customs documents is subjected to cross-checking via the integration between VEDOP (Tax Office Automation Project) and the Customs Information System (BİLGE). The slightest discrepancy in the documents can cause the refund process to be delayed for months.

Impacts on Customs and Foreign Trade Processes

This radical amendment to tax legislation directly impacts the field operations of foreign trade. Coordination among customs administrations, tax offices, and other public institutions acquires critical importance during the customs clearance phases of nuclear power plant investments. Beyond serving merely as a financial incentive, the regulation has necessitated the recalibration of customs regimes and logistical flows.

Declaration of VAT Exemption on the Customs Declaration

During the actual importation of goods into the customs territory of Turkey, utilizing the investment incentive certificate VAT exemption right requires populating the relevant boxes of the Customs Declaration with the correct legislative codes. The IIC number, its date, and special exemption codes denoting Provisional Article 47 of the VAT Law—which serve as the basis for the exemption—must be entered into the respective boxes designated for regime and additional information declarations on the form.

Entered into the BİLGE system by the customs broker, these data ensure that the goods are evaluated under the release for free circulation regime. Not only VAT, but if the investment incentive certificate also includes a Customs Duty exemption, both exemptions are displayed simultaneously on the declaration. However, it must be taken into account that due to potential origin-based additional obligations, the requirement to submit documents such as a Certificate of Origin or an A.TR Movement Certificate may persist. Even if a VAT exemption is granted, other foreign trade policy measures such as Additional Customs Duty (İGV) or Additional Financial Obligations (EMY), which may arise depending on the origin of the goods, may continue to be applied according to the tariff of the goods. For this reason, tariff determination and document inspection are managed with the utmost precision while preparing the customs declaration.

Financial Advantages in the Supply Chain and Import Processes

The supply chain of nuclear power plants possesses a complex structure encompassing heavy cargo logistics, special project transportation, and bonded warehouse management. When the customs VAT exemption is activated in nuclear investments, the standard rate VAT amount currently in effect, which the importing company would ordinarily have to pay upfront to the customs cashier, is generally zeroed out. In machinery imports worth hundreds of millions of dollars, this translates into a massive retention of cash within the company’s treasury.

This acquired financial advantage minimizes credit utilization needs and financing (interest) expenses for the project. Furthermore, once the goods are presented to the customs administration, the time that would otherwise be lost in processes such as seeking financing for tax payments or obtaining letters of guarantee is saved. Customs clearance procedures are completed more swiftly, allowing the goods to be rapidly dispatched from the port or warehouse to the construction site. Decreasing logistics and bonded warehouse waiting times lowers storage costs while simultaneously allowing the construction schedule to progress in accordance with the planned program. Ultimately, Provisional Article 47 of the VAT Law has taken its place in the foreign trade ecosystem as a strategic instrument that maximizes not only the tax efficiency of nuclear energy investments but also their overall supply chain performance and operational execution.
