How SAF-T is transforming tax reporting and why it matters to CFOs and CEOs

Tax digitalization is no longer an abstract concept, but a reality that is changing the way Romanian companies manage their financial data. At the heart of this transformation is SAF‑T, an international standard adopted by Romania to modernize reporting to ANAF and increase tax transparency.

For CFOs, CEOs and procurement department leaders, SAF‑T is not just a technical obligation. It is a test of organizational maturity and, at the same time, an opportunity to put order in data, processes and systems.

What is SAF‑T and why has it become so important in Romania

SAF‑T (Standard Audit File for Tax) is a standardized electronic file that allows for the structured transmission of accounting and tax data to tax authorities.

Romania introduced SAF‑T reporting starting in 2022 for large taxpayers, later extending the obligation to medium and small taxpayers. The goal? More granular, more coherent and easier to analyze reporting by ANAF.

In practice, SAF‑T means that companies must periodically submit the D406 declaration, which includes detailed information about transactions, VAT, partners, stocks and assets.

Why SAF‑T is a strategic topic for business leaders

For CFOs, SAF‑T is a complete x-ray of the quality of accounting data. Any inconsistencies, whether it be VAT codes, outdated partners or misaligned accounting accounts, become immediately visible. And that can be a good thing: it allows for the rapid identification of risks and their correction before a tax audit.

For a CEO, SAF‑T is an indicator of the company’s digital maturity. An organization that can generate a correct, complete and timely D406 file is an organization with solid processes, clean data and a culture oriented towards efficiency and transparency.

Purchasing departments play a key role in the selection of SAF‑T solutions. A successful implementation depends on ERP compatibility, the ability to handle large volumes of data, and the technical support provided by the vendor. A wrong choice can mean additional costs and delays in reporting.

What the SAF-T file contains and why it is so complex

SAF-T is not a simple declaration, but a large set of structured information. Among the mandatory elements are:

• accounting transactions (sales, purchases, payments, receipts)
• VAT information
• customer and supplier data
• details of stocks and their movements
• information on assets and depreciation
• the chart of accounts and related balances

This high granularity is why SAF-T can seem intimidating at first. It is also why it can become a valuable internal control tool.

When to submit SAF‑T and what the reporting calendar looks like

Romania has implemented SAF‑T in stages, depending on the taxpayer category. The obligation to submit the D406 declaration came into force as follows:

• January 1, 2022: large taxpayers
• January 1, 2023: medium taxpayers
• January 1, 2025: small taxpayers and non-residents

The reporting frequency varies depending on the type of information and the company’s fiscal period:

• Monthly or quarterly: for the general sections (transactions, partners, VAT). The deadline is aligned with the company’s VAT fiscal period (non-VAT taxpayers report quarterly).
• Annually: for the “Assets” section, until the deadline for submitting the annual financial statements.
• On request: for the “Inventories” section, which is submitted only at the express request of ANAF, within 30 days of receiving the request.

This phased structure allowed companies to adapt gradually, but also created challenges for organizations with complex structures or outdated IT systems.

The challenges for companies in implementing SAF‑T

1. Data quality

Data quality becomes essential in the context of SAF‑T, as the D406 file functions as an extremely accurate “scanner” of all accounting information. Any error, inconsistency or incomplete field is immediately visible to ANAF. For companies, this means the need for rigorous data cleaning, updating partners, aligning VAT codes and verifying the accounting structure. Without these adjustments, reporting can generate tax risks and operational delays.

2. Systems integration

Systems integration is one of the biggest challenges, especially for organizations using old or highly customized ERPs. Extracting data in the format required by ANAF requires a flexible and well-documented IT architecture. If systems do not communicate effectively with each other, bottlenecks, incomplete exports, or costly manual interventions can occur. That is why many companies are finding that SAF-T is a catalyst for digital infrastructure modernization.

3. Limited internal resources

Finance teams already deal with a high volume of recurring activities, and SAF‑T adds an additional layer of complexity. Preparing data, validating it, correcting errors, and generating the D406 file requires time, attention, and technical skills. In many organizations, this effort overlaps with busy periods, such as month-end closes or annual audits. Without additional resources or automation, the pressure on the team can become significant.

4. The need for strong governance

SAF‑T is not a project with a beginning and an end, but an ongoing process that requires organizational discipline. To report accurately and consistently, companies need clear procedures, well-defined responsibilities, and a transparent approval flow. Continuous data monitoring, updating internal rules, and collaboration between finance, IT, and operations become essential. Strong governance not only reduces risks, but also increases long-term efficiency.

How SAF‑T can become a competitive advantage

Although it may seem counterintuitive, SAF‑T can bring real benefits to companies that approach it strategically.

• Accelerated digitalization: implementing SAF‑T can be the right time to modernize ERP or adopt automation solutions.
• Better data, better decisions: cleaning and standardizing data improves not only tax reporting, but also internal financial analysis.
• Tax risk reduction: a correct and complete D406 file reduces the likelihood of unforeseen audits.
• Operational efficiency: automating reporting processes frees up time for value-added activities.

SAF‑T is just the beginning and goes beyond the status of simple periodic reporting; it constitutes the database necessary for cross matching with the RO e-Factura and RO e-Transport transactional systems.

As ANAF operationalizes its capacity to automatically process these massive volumes of data, tax compliance requires a fundamental change in approach.

The management objective is no longer the simple filing of a declaration, but ensuring the traceability and coherence of information across all state channels. An integrated and rigorously validated data structure represents, in this new context, the main method of mitigating the risk of tax inspections.

In addition, this process prepares companies in advance for the upcoming European digital reporting standards, which will become mandatory through the ViDA (VAT in the Digital Age) directive.

ViDA will impose a harmonized system of Mandatory Digital Reporting (DRR) based on electronic invoicing for all cross-border B2B transactions. This mechanism will replace the recapitulative statements (D390), ensuring a transactional, near-real-time data flow.

It is important to note that this European reporting will not replace the SAF-T declaration, the two systems working complementary.

For business leaders, the direction is clear: tax digitalization is a process with no way back. The ultimate goal is a fully digital tax ecosystem, where data flows quickly, consistently and transparently. For companies that are prepared, this evolution means predictability, efficiency and better control over risks.

In conclusion

SAF-T is not just a tax obligation, but a transformational opportunity. For CFOs, CEOs and procurement, it is the ideal time to strengthen the digital infrastructure, improve data quality and build a more robust and transparent financial environment. Companies that view SAF‑T as a strategic project, not just a legal requirement, will be the ones that will benefit the most from this change.
