Tax obligations for April 2026: an essential guide for businesses and taxpayers in Romania

The April 2026 tax calendar and what it means for businesses

The National Agency for Fiscal Administration (ANAF) has published the calendar of tax obligations for April 2026, a mandatory reference for every business and individual taxpayer in Romania. For entrepreneurs, knowing the exact deadlines and tax forms is crucial to avoid penalties, maintain healthy cash flow and plan finances properly.

In April, ANAF requires several important documents to be submitted, notably the Standard Audit File for Tax (SAF-T) – Form D406 and the Value Added Tax Return – Form 300. These obligations are not merely a procedural formality: they are an important reporting stage that directly affects access to tax facilities and compliance with the legislation in force.

The SAF-T file and the VAT return: what you need to know

The SAF-T file is an electronic tool designed to facilitate the exchange of accounting and tax information between taxpayers and the authorities. Form D406 is an essential part of this process for companies that exceed a certain turnover threshold or operate in certain closely supervised sectors. In practice, preparing SAF-T correctly requires careful integration of internal accounting processes and data controls, and errors can lead to checks and penalties.

The VAT return (Form 300) is a monthly report on value added tax collected and deducted. The attention this document deserves is justified by the considerable volume of transactions involved and its fiscal impact. Businesses must keep rigorous records of purchases and sales to meet this obligation, especially as ANAF has stepped up its checks in recent years to prevent VAT fraud.

Which taxpayers are affected and what documents are needed

The April tax obligations affect a wide range of entities: from micro-enterprises and SMEs to large corporations and individual taxpayers carrying out professional or commercial activity. Taxpayers who have changed their tax structure or modified their CAEN code must also submit the statement of changes concerning the change of tax period, for example the VAT registration threshold.

To prepare the reports, businesses must make sure they have access to all accounting documents, including invoices issued and received, cash and bank registers, and any other records that influence the tax base. The accuracy of these documents is essential to avoid rejected returns, delays or additional penalties.

The impact of tax obligations on the Romanian business environment

Complying with the tax calendar is an indicator of a company's economic maturity and tax integrity. The clear deadline set by ANAF for April 2026 comes amid ongoing tax reforms and the accelerated digitalisation of the tax administration. In this respect, companies that adapt quickly to electronic reporting requirements can reduce their operating costs and the risk of penalties.

In the long term, efficient and predictable tax management helps build investor confidence and a stable business environment. In addition, companies that strictly follow the tax calendar are more likely to access European programmes or tax facilities, which are sometimes conditional on an impeccable tax record.

Practical recommendations for businesses in April 2026

• Check submission deadlines well in advance and make sure all data is correct and complete.
• Strengthen cooperation between the accounting, tax and IT departments to prepare the SAF-T file correctly.
• Keep clear records of invoices and business transactions, using accounting software compatible with ANAF requirements.
• Keep an open dialogue with your tax adviser or EU funding expert to identify tax optimisation opportunities and prevent potential errors.
• Prepare the documentation for any adjustment related to a change of tax period or CAEN code, submitting the statements of changes within the set deadline.

Entrepreneurs should see these obligations not as a mere bureaucratic exercise but as an important step in the healthy and sustainable management of their business. Correct tax management protects the company against administrative risks and lets you focus on growing and developing your business.
