VAT Carry-Forward After the High Court Clarification: A Structural Distinction, Not a Procedural Nuance

The recent communication issued by the High Court of Cassation and Justice on 20 April 2026 clarifies a point that has long generated inconsistent administrative practice: the legal nature of the right to carry forward a negative VAT balance. The Court’s position does not introduce a new rule, but rather restores a structural distinction inherent to the VAT system. The right to carry forward a negative VAT balance is not subject to limitation periods, as it does not constitute a standalone claim, but a mechanism embedded in the logic of VAT settlement itself. The practical consequences of this clarification are significant, particularly in audit and litigation contexts where tax authorities have historically treated carry-forward balances as extinguished by the passage of time.

VAT Carry-Forward – Between Accounting Mechanism and Tax Claim

The distinction between VAT refund and VAT carry-forward is not merely procedural, but conceptual.

A VAT refund implies the existence of a claim against the state, subject to procedural requirements and limitation periods. By contrast, the carry-forward of a negative VAT balance operates within the ongoing functioning of the tax system, being reflected continuously in subsequent VAT returns.

The High Court’s clarification confirms that this distinction is not optional. Carry-forward is not a right that must be exercised within a defined timeframe, but a structural component of VAT computation. As such, it cannot be extinguished independently of the tax mechanism it serves.

This approach aligns with the internal logic of VAT neutrality. A negative balance represents input VAT exceeding output VAT in a given period, and its carry-forward ensures that taxation reflects economic reality over time, rather than being artificially constrained by procedural limitations.


Implications for Tax Practice – From Limitation to Continuity

The immediate impact of this clarification is most visible in situations involving historical VAT balances.

In audit practice, tax authorities have frequently challenged the use of older negative VAT amounts, arguing that the right to recover or use such balances had become time-barred. The High Court’s position directly undermines this approach by distinguishing between recovery (refund) and offset (carry-forward).

This has two key consequences.

First, taxpayers retain the ability to use historical negative VAT balances in subsequent periods, regardless of their age. The passage of time does not affect the existence of the balance as part of the VAT computation chain.

Second, disputes previously framed around prescription may need to be reframed entirely. The focus shifts from whether a right was exercised within a given period to whether the balance itself is legally and factually justified.


The Limits of the Clarification – Refund vs. Offset

It is important to note that the High Court’s clarification does not eliminate limitation periods in VAT matters altogether.

The distinction remains intact:

  • the right to request a VAT refund is subject to limitation;

  • the right to carry forward a negative VAT balance is not.

This distinction is essential from a strategic perspective. A taxpayer may lose the ability to obtain a cash reimbursement of VAT, while still retaining the ability to offset that amount against future VAT liabilities.

In practice, this creates a dual regime where the same underlying amount may be treated differently depending on the mechanism used.


Repositioning VAT Disputes – Substance Over Procedure

From a litigation standpoint, the clarification introduces a shift in how VAT disputes should be structured.

Arguments based on prescription are no longer sufficient to eliminate historical VAT balances. Instead, tax authorities will need to challenge the substantive validity of those balances, including the underlying transactions and supporting documentation.

For taxpayers, this opens a more stable defensive position. The focus moves away from procedural deadlines and toward the economic and legal substance of the VAT position.


Conclusion

The High Court of Cassation and Justice does not redefine VAT law, but clarifies one of its core structural elements.

The right to carry forward a negative VAT balance is not a time-bound entitlement, but a continuous mechanism within the VAT system. Its recognition as such restores coherence between domestic practice and the principle of VAT neutrality.

For taxpayers and practitioners, the message is clear: limitation may restrict recovery, but it does not erase the balance itself.
