A technology company incorporated in the Netherlands appoints a Romanian-based director who runs daily operations from Bucharest. Six months later, the Romanian tax authority issues a notice asserting that the company is a Romanian tax resident – and that it owes corporate income tax on its worldwide profits. The company's management is caught entirely off guard. This scenario is not hypothetical. It recurs across international business structures operating in or through Romania, and the financial exposure it creates can be severe.
Tax residency in Romania is determined by distinct rules for companies and individuals, each with separate triggers, documentary requirements, and compliance timelines. For companies, the primary tests are place of incorporation and place of effective management. For individuals, the decisive factors are domicile, habitual abode, and physical presence exceeding 183 days within any 12-month period. Misreading either set of rules can generate unexpected tax liability under Romanian tax legislation.
This guide walks through each step of the residency determination process, sets out the documentary checklist. Flags the most common errors made by foreign clients. Additionally, offers a decision framework for the most frequent business scenarios encountered in practice.
Step 1 – Understanding the legal tests that determine residency
Romanian tax legislation applies separate residency tests to legal entities and to natural persons. Understanding which test applies – and why – is the essential first step before any registration or compliance action is taken.
For companies: A legal entity is treated as a Romanian tax resident if it is incorporated under Romanian corporate legislation, or if its place of effective management is located in Romania. The second limb – effective management – is the one that catches foreign companies off guard. It applies regardless of where the company is incorporated.
The place of effective management is the location where senior management decisions concerning the business as a whole are made. Romanian tax authorities assess this by looking at where board meetings are held, where directors are physically present when making decisions, where corporate records are kept, and where the company's principal commercial activity is directed.
A foreign company managed by a Romanian-resident director who attends every board meeting from Bucharest, communicates with clients from Romania, and keeps corporate files in a Romanian office will likely satisfy the effective management test. The formal registered address abroad offers little protection in that scenario.
This situation also engages the concept of a sediu permanent (permanent establishment) under Romanian tax legislation and applicable tax treaties. A permanent establishment that falls short of full residency still generates Romanian-source taxable income. The line between a permanent establishment and full tax residency is consequential: a permanent establishment is taxed only on attributable profits. While a resident entity is taxed on worldwide income subject to any available tax treaty relief.
For individuals: A natural person becomes a Romanian tax resident if they have their domicile in Romania. If they have their centre of vital interests in Romania. Alternatively, if they are physically present in Romania for more than 183 days within any 12-month period. The 183-day test counts all days of physical presence, including partial days of arrival and departure.
The centre of vital interests test is broader than physical presence. It captures individuals whose principal economic and personal ties are in Romania. for example, where their family resides, where their primary bank accounts are held, and where the majority of their business activity is generated.
Practitioners in Romania note that the 183-day trigger is frequently underestimated by digital nomads and mobile executives who assume that holding a tax residency certificate from another country insulates them from Romanian claims. That assumption is wrong. If the factual criteria under Romanian tax legislation are satisfied, Romanian residency arises regardless of foreign certificates – unless a tax treaty provides a tiebreaker that resolves the conflict in favour of the other jurisdiction.
Step 2 – Procedural requirements and documentary checklist
Once a residency position has been identified. whether to confirm it, establish it formally. Alternatively. Contest a claim. the procedural steps with the Romanian tax authority (Agenția Națională de Administrare Fiscală. Alternatively, ANAF) must be followed precisely.
For detailed support on the full range of tax compliance obligations that attach once residency is established, see the firm's overview of tax law services in Romania.
For companies establishing Romanian tax residency:
- Certificate of incorporation or equivalent constitutional document, apostilled and translated into Romanian
- Articles of association or equivalent constitutive document
- Proof of registered address in Romania (lease agreement or property title)
- Evidence of the place of effective management (board minutes, correspondence records, organisational charts)
- Identification documents for all directors and shareholders holding a significant interest
- Power of attorney authorising a Romanian-based representative, if the application is filed through an agent
The company must obtain a cod de identificare fiscală (Romanian tax identification number) from ANAF. This registration is a prerequisite for filing corporate income tax returns, registering for withholding tax obligations, and accessing the benefits of any applicable tax treaty.
For individuals claiming or confirming Romanian tax residency:
- Valid identity document or passport
- Proof of domicile or habitual abode in Romania (rental contract, utility bills, property registry extract)
- Evidence of centre of vital interests where domicile alone is insufficient (bank statements, employment contract, school enrolment records for dependants)
- Travel records or border crossing history where the 183-day test is the primary basis
- Foreign tax residency certificates, where a treaty tiebreaker analysis is required
Individuals must register with ANAF and obtain a personal tax identification number. This number is required for filing annual income tax returns, for triggering withholding tax exemptions on Romanian-source income, and for invoking treaty protection against double taxation.
Timeline: A well-prepared application typically takes two to six weeks to process. Where the file is incomplete or where ANAF raises questions about the effective management analysis, the process can extend to three months or beyond. Companies with complex group structures should build at least eight weeks of preparation time before the intended effective date of residency.
For companies that are also considering their wider legal structure in Romania, the interaction between tax residency and corporate governance requirements is covered in our guide to corporate law in Romania.
Step 3 – Common errors by foreign clients and how to avoid them
The majority of problems encountered by international businesses in this area arise from a small set of recurring mistakes. Each carries a distinct risk profile.
Assuming incorporation determines everything. Many clients believe that registering a company in a low-tax jurisdiction is sufficient to fix tax residency there. In practice, if day-to-day management and strategic decisions happen in Romania, Romanian tax legislation will assert residency claims. The formal structure and the operational reality must be aligned. Where they diverge, the operational reality will prevail in most cases.
Ignoring the effective management test when appointing local directors. Appointing a Romanian-resident director as the sole or dominant decision-maker creates a strong presumption of Romanian effective management. This is not inherently problematic – but it must be planned for. Documentary hygiene matters: board minutes should reflect that decisions are made collectively, at properly convened meetings, in the jurisdiction of intended residency.
Underestimating treaty interaction. Romania has concluded tax treaties with a significant number of jurisdictions. Where dual residency arises – for example, because both Romania and a foreign state assert that the same company or individual is resident – the applicable tax treaty contains tiebreaker rules that resolve the conflict. Many clients are unaware that invoking treaty protection requires affirmative action: filing the correct forms with ANAF and, in some cases, initiating a mutual agreement procedure between the two tax authorities. Delay in doing so can result in double taxation that becomes practically difficult to unwind.
Missing withholding tax obligations. A Romanian tax resident company that makes payments to foreign entities – dividends, interest, royalties, service fees – may be subject to withholding tax obligations under Romanian tax legislation. The applicable rate depends on the payment type and on whether a tax treaty reduces or eliminates it. Failure to apply withholding tax correctly, or to file the required returns, exposes the company to interest and penalties that accumulate from the date the obligation arose.
Failing to account for exit taxation. An individual or company that was previously a Romanian tax resident and intends to relocate residency to another jurisdiction must formally notify ANAF and comply with exit procedures under Romanian tax legislation. Failure to do so means that Romanian residency continues to apply – and that worldwide income remains subject to Romanian corporate income tax or personal income tax – until the exit is formally completed.
Step 4 – Decision framework for common business scenarios
The right approach to Romanian tax residency varies significantly depending on the client's commercial objectives and existing structure. The following scenarios illustrate the principal decision points.
Scenario A – Foreign company opening a Romanian branch or subsidiary. Where the intention is to establish a genuine operational presence in Romania, registering as a Romanian tax resident company is typically the correct outcome. The company should ensure that its constitutional documents, governance structure, and operational records all reflect Romanian management. This maximises access to Romania's tax treaty network and avoids the risk of an involuntary residency claim being made on unfavourable terms.
A critical question in this scenario is whether the entity should be structured as a branch. which is treated as a permanent establishment. Taxed only on Romanian-attributable profits. or as a wholly-owned subsidiary. This is a separate Romanian tax resident entity. The choice affects corporate income tax exposure, withholding tax on profit repatriation, and transfer pricing obligations within the group.
Scenario B – Individual relocating to Romania for employment or self-employment. An individual taking up Romanian employment, or operating a business from Romania, should assess residency exposure before the first day of presence. If residency is intended, the registration process with ANAF should begin promptly. If residency is not intended. for example, because the individual plans a short-term assignment. the 183-day threshold must be tracked carefully from the first day of presence. Additionally. Any treaty protection must be documented in advance.
Scenario C – Digital nomad or remote worker spending extended periods in Romania. This is the scenario most likely to generate unintentional residency. A foreign national who enters Romania without an employment contract, works remotely for a non-Romanian employer. Additionally. Spends more than 183 days in the country within a 12-month period may acquire Romanian tax residency without taking any affirmative step. The consequences can include liability for personal income tax on worldwide income, obligation to file an annual Romanian return. Additionally. Potential double taxation with the country of prior residency if no treaty tiebreaker is invoked in time.
Specialists in this area strongly recommend that remote workers assess their position before the 183-day threshold is approached – not after it is crossed. Remediation after the fact is significantly more burdensome than advance planning.
Scenario D – Holding company in Romania receiving dividends from subsidiaries. A Romanian-resident holding company that receives dividends from subsidiaries in other jurisdictions must consider both the domestic participation exemption rules under Romanian tax legislation and the withholding tax treatment in the subsidiary's jurisdiction. Where the subsidiary is located in a jurisdiction with which Romania has a tax treaty, the applicable withholding tax rate on outbound dividends is typically reduced. The holding company must hold the relevant residency certificate and meet the conditions specified in the treaty to benefit from the reduced rate.

Self-assessment checklist before taking action
This guide is applicable to your situation if one or more of the following conditions is present:
- You are incorporating or have already incorporated a company in Romania and need to confirm its tax residency status
- You are a foreign company with Romanian-based management and wish to assess whether an effective management claim could be made against you
- You are an individual planning to spend more than three months in Romania in any calendar year
- You are receiving Romanian-source income – dividends, interest, royalties, or service fees – and need to assess withholding tax obligations
- You are planning to relocate tax residency away from Romania and need to manage exit obligations
Before initiating any registration or compliance action, verify the following critical items:
- Is there an applicable tax treaty between Romania and the other jurisdiction of interest – and does it contain a tiebreaker rule?
- Are your board minutes and management records consistent with your intended place of effective management?
- Have you tracked your physical presence days in Romania from the first day of entry?
- Are your withholding tax obligations on outbound payments correctly identified and documented?
- Have you obtained the necessary residency certificates from the relevant foreign authority to invoke treaty protection with ANAF?
Frequently asked questions
Q: How long does it take to establish tax residency in Romania for a company?
A: Registration with the Romanian tax authority typically takes between two and six weeks from submission of a complete file. Delays most often result from missing documentation or inconsistencies in the corporate structure. Building preparation time into the timeline – ideally four to eight weeks before the intended effective date – is strongly advisable.
Q: Does incorporating a company in Romania automatically make it a Romanian tax resident?
A: Incorporation under Romanian corporate legislation does create a presumption of tax residency. However, that presumption can be displaced if the place of effective management is demonstrably located in another jurisdiction. Foreign authorities may also assert their own residency claims if key decision-making consistently occurs outside Romania, creating a dual-residency situation that requires resolution under an applicable tax treaty.
Q: Can a foreign individual working remotely in Romania become a Romanian tax resident unintentionally?
A: Yes – this is one of the most common misconceptions among digital nomads and internationally mobile professionals. A foreign national who spends more than 183 days in Romania within a 12-month period, or who establishes a habitual abode there, may acquire Romanian tax residency automatically under Romanian tax legislation. Engaging a lawyer in Romania before a significant stay begins is the most reliable way to assess exposure and structure the position correctly.
