Vat One Stop Shop in Romania: Registration, Filing, and Benefits Explained

VAT OSS in Romania simplifies EU VAT compliance for businesses making cross-border B2C sales. The scheme allows eligible businesses to report and pay VAT on EU consumer sales through a single quarterly return filed with Romania’s tax authority, ANAF (Agenția Națională de Administrare Fiscală). 

Introduced on July 1, 2021, OSS replaced the former distance-selling rules and removed the need for multiple VAT registrations across EU member states, covering both Union and Non-Union OSS.

The OSS framework reduces administrative burden by consolidating VAT reporting into one return. Businesses may register in Romania even without a local establishment, provided they meet the eligibility conditions. 

This guide explains VAT OSS in Romania, including registration, filing obligations, EU VAT rates, and record-keeping requirements to support compliant cross-border operations.

Key Highlights

• Single registration replaces multiple EU VAT numbers: Through the EU VAT One-Stop Shop (OSS), businesses can register in one EU member state, such as Romania, and report eligible cross-border B2C sales across all 27 EU countries in a single quarterly VAT return.
• €10,000 EU-wide threshold: After €10,000 in intra-EU sales, VAT applies in the customer’s country and can be reported through OSS, with optional early opt-in below the threshold.
• Romania’s 21% standard VAT rate: Understand destination-based taxation requiring application of customer country rates ranging from 17% to 27% across the EU
• 10-year record retention mandatory: Maintain comprehensive transaction records, customer location evidence, and VAT calculations for 10 years from December 31 of the transaction year
• SPV electronic platform: ANAF provides Spațiul Privat Virtual (SPV) for electronic filing with Romanian and limited English support

Understanding the VAT OSS Scheme in Romania

The VAT One Stop Shop (OSS) is an EU-wide electronic portal system that simplifies VAT compliance for businesses making cross-border business-to-consumer (B2C) sales within the European Union. Romania participates in this harmonized system through the National Agency for Fiscal Administration (ANAF), allowing businesses to register, file returns, and remit VAT for sales across all EU member states through a single portal.

Two OSS Schemes

Romania’s OSS system operates through two distinct schemes:

Union OSS: For EU-established businesses making:

• Cross-border supplies of goods to consumers in other EU member states
• Intra-EU distance sales of goods
• Domestic supplies of services to non-taxable persons in other EU member states

Non-Union OSS: For non-EU businesses making:

• Supplies of telecommunications, broadcasting, and electronically supplied services (TBE services) to EU consumers
• Does NOT cover physical goods

What Is the VAT OSS Scheme?

The VAT One Stop Shop (OSS) is a special EU-wide compliance mechanism that simplifies cross-border VAT obligations, effective July 1, 2021, as part of the EU’s e-commerce VAT package. It replaced the previous complex distance-selling threshold system that created a significant administrative burden for businesses.

After OSS (Post-July 2021)

The system now provides:

• Single EU-wide threshold of €10,000 for all intra-EU distance sales combined
• One registration in a single member state, like Romania
• One quarterly return covering all cross-border B2C sales
• One payment to the registration country, which distributes VAT to consumption countries
• Cooperation with one tax authority in one language

Union vs. Non-Union OSS

The OSS framework operates through two distinct schemes, depending on where a business is established and the type of supplies it makes. The table below compares Union OSS and Non-Union OSS to clarify eligibility, covered transactions, and typical use cases.

Who Must Register for VAT OSS in Romania?

OSS registration is optional but beneficial for eligible businesses. There is no mandatory registration unless a business chooses to use the scheme.

Union OSS – Who Can Register

Romanian-Established Businesses:

Must register in Romania if making:

• Cross-border distance sales of goods to consumers in other EU member states
• Supplies of services to consumers in other EU member states
• Distance sales of goods imported from third countries (≤€150 value)

Romanian businesses cannot choose another member state for Union OSS registration.

Other EU Businesses:

Can register for Union OSS in Romania if they prefer, though they typically register in their establishment country.

Eligibility Criteria:

• Must be VAT-registered or VAT-identifiable in at least one EU member state
• Only one Union OSS registration is allowed across the entire EU
• Cannot use Union OSS for sales in your establishment country (use domestic VAT)

Non-Union OSS – Who Can Register

Non-EU Businesses:

Can register in Romania if supplying:

• Telecommunications services to EU consumers
• Broadcasting services to EU consumers
• Electronically supplied services to EU consumers

Eligibility Criteria:

• No EU establishment required
• Can register in any EU member state
• Only one Non-Union OSS registration allowed
• Must not be required to register for VAT in any EU country for other reasons

When Registration Makes Sense

Romanian businesses exceeding the €10,000 threshold for intra-EU distance sales must either:

• Register for OSS, or
• Obtain separate VAT registrations in each destination country

Below this threshold, businesses can charge Romanian VAT (21%) or voluntarily join OSS for simplified compliance.

Benefits of OSS VAT Registration in Romania

OSS registration offers significant administrative and operational advantages for qualifying businesses.

Single Registration

Register once in Romania instead of in every EU member state, eliminating:

• Multiple VAT registration processes across 27 countries
• Different tax authority relationships and portals
• Varied local requirements and languages
• Ongoing compliance with multiple national rules

Single Quarterly Return

File one consolidated VAT return every quarter covering all cross-border B2C sales, rather than:

• Monthly or quarterly returns in multiple countries
• Different filing deadlines and formats
• Multiple payment procedures and currencies
• Varied reporting requirements

Simplified Payment

Pay all VAT due across the EU in a single payment to ANAF, which then distributes amounts to respective member states. This eliminates:

• Multiple foreign currency payments
• Different payment methods and banking arrangements
• Tracking payments across multiple tax authorities
• Currency conversion complications

No Local Representation Required

OSS registration typically doesn’t require local fiscal representatives or agents in other EU countries, reducing:

• Representative fees and costs
• Administrative coordination burden
• Dependency on third-party compliance partners

Harmonized Rules

OSS applies consistent EU-wide rules and procedures, providing:

• Predictable compliance framework
• Standardized reporting formats
• Clear guidance on applicability
• Reduced risk of local interpretation variations

Reduced Administrative Burden

Businesses report that OSS reduces VAT compliance workload by 60-80% compared to multiple registrations, allowing:

• Reallocation of resources to the core business
• Reduced compliance costs
• Fewer audit and query management requirements
• Simplified internal processes

How to Register for OSS VAT in Romania

Registration for OSS in Romania is completed through ANAF’s Spațiul Privat Virtual (SPV) electronic portal. The process differs for Union OSS and Non-Union OSS.

Union OSS Registration Steps

Step 1: Ensure VAT Registration

Romanian-established businesses must first hold a valid Romanian VAT registration (CUI – Cod Unic de Înregistrare) before applying for OSS. If not yet VAT-registered, complete standard VAT registration through ANAF first.

Step 2: Access SPV Portal

Navigate to anaf.ro and access Spațiul Privat Virtual using:

• Digital certificate, or
• Username and password credentials

Step 3: Locate OSS Registration Section

Within the SPV portal:

• Navigate to the VAT (TVA) section
• Select “OSS Registration” or “Înregistrare OSS”
• Choose the Union OSS registration option

Step 4: Complete Registration Application

Provide required information:

• Business identification details (name, CUI number, registration number)
• Contact information (email, phone)
• Description of business activities eligible for OSS
• List of EU member states where supplies are expected
• Bank account details for potential refunds (IBAN format)
• Declaration confirming eligibility and understanding of obligations

Step 5: Submit Application

Submit the electronic application through SPV. For Romanian-established businesses already in the ANAF system, no physical documents are typically required.

Step 6: Await Confirmation

• ANAF reviews the application and verifies eligibility
• Upon approval, assigns OSS VAT identification number (format: EU642xxxxxxxxx for Romania)
• Confirmation sent through SPV messaging system and email

Effective Date: Registration takes effect on the first day of the calendar quarter following approval. Cannot be backdated to previous quarters.

Non-Union OSS Registration Steps

Step 1: Access Non-Union OSS Portal

Non-EU businesses access ANAF’s dedicated Non-Union OSS registration interface through the SPV system.

Step 2: Create Account

Establish user credentials:

• Complete the online registration form
• Provide email address
• Create a secure password following ANAF requirements

Step 3: Complete Registration Form

Provide business details:

• Legal business name and registration information from the home country
• Business address outside the EU
• Contact person details
• Email address for official communications
• Description of TBE services provided
• Declaration of non-EU establishment status

Step 4: Submit Application

Submit the electronic application. ANAF may request additional documentation to verify non-EU status and business legitimacy.

Step 5: Receive Confirmation

Upon approval, ANAF provides:

• Non-Union OSS identification number
• SPV portal access credentials for filing returns

Procedure for VAT OSS Filing in Romania

OSS returns are filed quarterly through the SPV electronic portal with specific deadlines and requirements.

Filing Deadlines

Returns must be submitted by the last day of the month following quarter end:

• Q1 (Jan-Mar): Due by April 30
• Q2 (Apr-Jun): Due by July 31
• Q3 (Jul-Sep): Due by October 31
• Q4 (Oct-Dec): Due by January 31 (following year)

Filing Process

Step 1: Gather Sales Data

Compile for the quarter:

• All cross-border B2C sales by the destination member state
• Sales values in euros (convert RON to EUR using ECB rates)
• Applicable VAT rates by country and product/service
• Any credits, returns, or adjustments

Step 2: Access SPV OSS Section

Log in to Spațiul Privat Virtual using your credentials and navigate to the OSS return section.

Step 3: Complete Quarterly Return

For each EU member state where supplies were made:

• Enter total net sales value (excluding VAT)
• Select applicable VAT rate(s) for that country
• The system calculates VAT due automatically
• Report separately for different rate categories if applicable

Step 4: Include Corrections

If necessary:

• Report corrections from previous quarters
• Indicate whether the adjustment increases or decreases VAT
• Provide a brief explanation for material adjustments

Step 5: Review and Submit

• Verify all data for accuracy
• Check calculated VAT amounts
• Review summary by the member state
• Submit the electronic return through SPV

Step 6: Payment

• Payment of the total VAT due must be made to ANAF by the same deadline
• Payment made through approved Romanian banking channels
• Use proper reference numbers for correct allocation
• Payment details provided in SPV upon submission

How VAT Rates Work Under the OSS System

Under OSS, sellers must apply the customer’s member state VAT rate under the destination principle, not the seller’s establishment country rate.

Determining Customer Location

Establish customer location using evidence such as:

• Billing address
• IP address
• Bank account location
• Mobile country code
• Other commercially relevant information

EU law requires at least two pieces of non-contradictory evidence.

Applying Destination Country Rates

Each EU member state sets its own VAT rates within EU minimums:

• Standard rate: minimum 15% (actual rates vary from 17% to 27%)
• Reduced rates: minimum 5% for specific goods/services
• Super-reduced and zero rates for limited categories

Sample VAT Rates Across the EU

VAT rates vary significantly across EU member states, making accurate rate application critical under the OSS system. The table below highlights standard and reduced VAT rates in selected countries to illustrate the range of VAT rates businesses must account for when reporting cross-border B2C sales.

Record-Keeping Requirements Under OSS

Businesses using OSS in Romania must maintain comprehensive records to support VAT compliance and withstand audits.

Retention Period

EU law requires OSS-related records to be kept for 10 years from December 31 of the year of the transaction. This standardized retention period applies uniformly across all EU member states for OSS documentation.

Records to Maintain

Transaction Documentation:

• Invoices or equivalent documents
• Sales values, dates, and descriptions
• Product/service classifications

Customer Information:

• Names and addresses
• Evidence of customer location
• Location proof: minimum two pieces (billing address, IP address, bank details, mobile country code)

Compliance Documentation:

• Quarterly OSS returns submitted
• Payment confirmations to ANAF
• VAT rate justifications and calculations by member state
• Credit notes, refunds, and adjustments
• Currency conversion records using ECB exchange rates

Format and Accessibility

Records must be:

• Stored electronically or in paper format
• Readily accessible for Romanian and other EU tax authorities
• Retrievable within reasonable timeframes upon request

Electronic storage, including cloud-based systems, is acceptable provided documents can be accessed promptly.

Common Issues When Using the OSS VAT System

Businesses using OSS in Romania may face recurring compliance challenges that can lead to errors or penalties if not addressed early.

Incorrect VAT Rate Selection

Applying the wrong country or rate often results from misidentified customer location, outdated rates, or product misclassification.

Fix: Use automated rate tools, verify location with multiple data points, maintain up-to-date EU rate databases, and review rates before each filing. Seek professional guidance for unclear classifications.

Incomplete or Inaccurate Filings

Missing transactions or calculation errors typically stem from weak data extraction, manual handling, or RON-to-EUR conversion issues.

Fix: Automate sales data capture, validate returns before submission, reconcile with accounting records, apply ECB exchange rates, and correct errors promptly.

Misunderstanding Union vs. Non-Union OSS

Errors arise when businesses register under the wrong scheme or include ineligible supplies, such as B2B or domestic sales.

Fix: Union OSS covers goods and services; Non-Union OSS applies only to TBE services. B2B uses reverse charge, and domestic sales belong in Romanian VAT returns.

Late Submission or Payment

Missed deadlines are often caused by poor internal tracking, cash-flow constraints, or SPV portal issues.

Fix: Set internal deadlines 5–7 days early, enable automated reminders, prepare returns early, and file even if figures require later correction.

Customer Location Determination

Conflicting evidence, VPN usage, or mismatched billing details can complicate location validation.

Fix: Collect multiple location indicators, apply consistent presumptions, and document decision logic.

Returns, Refunds, and Credit Notes

Uncertainty around timing and allocation of adjustments is common.

Fix: Report adjustments in the quarter issued, reduce VAT by member state and rate, allow negative amounts where required, and retain detailed supporting records.

Language Barriers

Romanian-language portals and official communications can slow compliance.

Fix: Use professional tax advisors, reliable translation tools, and request clarification from ANAF when needed.

Deregistering or Updating OSS Registration in Romania

Businesses must manage OSS registration changes carefully to remain compliant with Romanian and EU VAT rules. Deregistration or updates should be planned in advance to avoid reporting gaps or penalties.

When Deregistration Is Required

• Mandatory deregistration: It applies when a business stops making OSS-eligible supplies, no longer meets eligibility criteria (for example, an EU business becoming non-EU established), registers for OSS in another member state, or ceases operations entirely.
• Optional deregistration: It may be chosen when a business switches to local VAT registrations, reduces cross-border sales below OSS thresholds, or makes a strategic change to its compliance model.

Deregistration Process

Deregistration takes effect only at the end of a calendar quarter and cannot be completed mid-quarter. Businesses must first file all outstanding OSS returns, including any corrections, and settle all VAT due.

The deregistration request is submitted through SPV by completing the OSS deregistration form, selecting the quarter-end effective date, and stating the reason for deregistration. ANAF confirms deregistration through SPV, and the confirmation should be retained for records.

If cross-border sales continue after deregistration, businesses must register locally in destination member states, register for OSS in another member state, or ensure supplies fall under the B2B reverse-charge mechanism.

Updating OSS Registration

Certain changes must be reported to ANAF, including updates to legal name, address, contact details, bank accounts for refunds, or authorized representatives. Updates are made through the OSS registration section in SPV and usually take effect immediately, though material changes may require review.

Record Retention After Deregistration

Even after deregistration, OSS records must be retained for 10 years. ANAF continues to hold audit rights for all historical OSS periods.

Frequently Asked Questions About OSS in Romania

Q. Do I still need local VAT registrations in other EU countries if I join OSS in Romania?

Usually no. OSS replaces local VAT registrations for eligible cross-border B2C supplies. Local VAT registration may still be required for B2B transactions, domestic sales where you hold stock or an establishment, non-OSS supplies (such as excise goods or installation services), or to reclaim input VAT.

Q. What types of sales cannot be reported through the OSS VAT return in Romania?

OSS does not cover B2B supplies, domestic Romanian sales, excise goods, new means of transport, installation or assembly supplies, margin-scheme transactions, or VAT-exempt sales. Only eligible cross-border B2C goods and services can be reported.

Q. How does OSS affect distance-selling thresholds for businesses operating from Romania?

OSS introduced a single EU-wide €10,000 threshold. Above this, businesses must charge destination-country VAT via OSS or local registrations. Below it, Romanian VAT (21%) applies unless the business opts into OSS voluntarily.

Q. Can non-EU businesses register for OSS in Romania without a local establishment?

Yes, but only under Non-Union OSS for TBE services. Non-EU businesses cannot use Union OSS for goods without an EU establishment and must rely on IOSS, intermediaries, or local VAT registrations for physical goods.

Q. What happens if I file the OSS VAT return late or miss a payment in Romania?

Late filing or payment triggers penalties and interest from ANAF. Repeated non-compliance can lead to OSS exclusion, estimated assessments, and mandatory local VAT registrations. Zero returns must still be filed, and missed deadlines should be corrected immediately via SPV.

Q. How should refunds, cancellations, or credit notes be handled in an OSS VAT return?

Adjustments are reported in the quarter the refund or credit note is issued. VAT is reduced by the member state and rate, with negative amounts allowed. Detailed records linking adjustments to original transactions must be retained.

Q. Does joining the OSS scheme in Romania allow input VAT recovery?

No. OSS only covers output VAT reporting. Input VAT must be reclaimed through local VAT registration or the EU VAT refund procedure. OSS registration alone does not provide input VAT deduction rights.
