What the certificate is
A certificate of tax residency — certificat de rezidență fiscală — is a document issued by ANAF, the Romanian tax authority, confirming that a named person was resident in Romania for tax purposes in a given period. Its single practical function is to let that person claim relief under a double-taxation treaty: a foreign payer, or a former home-country tax authority, will not apply a reduced treaty rate on a payment until it holds the certificate on file.
The certificate is issued under the treaty-application provisions of the Codul Fiscal — Law 227/2015, Articles and — and on the model forms set by Order of the Minister of Finance / (OMFP /). There are separate models for natural persons and for legal persons, and separate models depending on whether the certificate is destined for a treaty partner or for domestic use.
The certificate does not make you a Romanian tax resident. It records that you already are one. That distinction decides whether you should be applying for it at all.
This is a companion to our guide on how Romanian tax residency is actually determined — the certificate sits downstream of that determination. If the residency itself does not hold, the certificate is worthless, and a foreign authority that later unpicks the position can reclaim the treaty relief with interest.
What it proves — and what it does not
The certificate is evidentiary, not constitutive. It proves a status that already exists under the substantive residency tests; it does not confer that status. This matters because founders frequently reverse the logic — they treat obtaining the certificate as the act that makes them Romanian tax resident, and it is not.
Specifically, the certificate:
- Confirms that the holder met the Romanian residency tests for the stated period, so that a treaty partner applies the reduced withholding or exemption the treaty provides.
- Names the treaty it is issued for — the standard OMFP / model recites "for the application of the Convention for the avoidance of double taxation between Romania and [State]".
- Covers a defined period, normally the calendar year in which it is issued, and is read by foreign payers as evidence for that year only.
The certificate does not:
- Create residency. Residency arises from domicile, permanent home, centre of vital interests, and the -day presence test under the Codul Fiscal, assessed independently. The certificate merely reports the result.
- Resolve a dual-residency conflict. Where two states both claim you, the treaty tie-breaker decides — and a Romanian certificate is one input into that analysis, not the answer to it.
- Guarantee acceptance. A foreign authority that believes your centre of vital interests remained at home can look behind the certificate. It is strong evidence, not a conclusive shield.
Because the certificate is only as good as the residency behind it, the substance work — physical presence, a permanent home in Romania, the family and economic connections — has to be real and documented before the certificate is requested, not assembled afterwards.
The certificate is not the arrival questionnaire
Two ANAF documents are routinely confused, and confusing them causes real filing errors.
The questionnaire for establishing fiscal residence on arrival in Romania — Chestionar pentru stabilirea rezidenței fiscale a persoanei fizice la sosirea în România — is the instrument by which residency is established and registered. An individual who arrives intending to stay, or who crosses the -day presence threshold in any consecutive months, files this questionnaire with the competent tax office, and ANAF then notifies the person whether they are subject to full Romanian tax liability on worldwide income or to limited liability on Romanian-source income only. That process is covered in detail in our 183-day rule guide.
The certificate, by contrast, is issued after residency is settled and is used purely to evidence it to a third party abroad. The questionnaire is an input to the residency determination; the certificate is an output of it. You file the questionnaire once on arrival and once on departure; you request the certificate whenever a foreign payer needs proof — often every year, for as long as the treaty relief is claimed.
File the questionnaire to become resident. Request the certificate to prove you already are. They are not interchangeable, and ANAF will not let one stand in for the other.
The application to ANAF
The certificate is requested from the competent ANAF administration — for an individual, the tax office of the person's Romanian domicile or registered residence; for a company, the office that administers the entity. The request is made on the standardised application form that accompanies the OMFP / models, and it is filed on paper at the registry or electronically through the Spațiul Privat Virtual (SPV) where the person is enrolled.
The application identifies:
- The applicant — name, cod numeric personal or cod de identificare fiscală (CNP or CIF), and Romanian address.
- The period for which residency is to be certified, normally the current calendar year.
- The treaty partner state in which the certificate will be used — the certificate is issued naming that convention.
- The purpose — the type of income (dividends, interest, royalties, employment, business profits) for which treaty relief is sought abroad.
For a legal person, the certificate confirms the company's Romanian residency by virtue of its incorporation and place of effective management, and is commonly requested to support treaty relief on cross-border payments received by the Romanian entity. For a natural person, the certificate confirms residency established through the tests above.
Documents required
ANAF issues the certificate against a file that lets it confirm the residency it is being asked to certify. For an individual, the supporting file typically includes:
- A completed application form in the OMFP / format, naming the treaty state and the period.
- Proof of Romanian residence — the ownership title, lease, or contract de comodat for the Romanian home, consistent with the permanent-home test.
- The residence permit (permis de ședere) for non-EU nationals, or the registration certificate for EU nationals, where relevant.
- Evidence supporting the underlying residency determination — the filed arrival questionnaire and ANAF's response, or prior-year returns showing worldwide-income taxation in Romania.
- Identification — passport or national identity document and the CNP/CIF.
For a company, the file is lighter: the certificat constatator from the Trade Register, the CUI, and confirmation that the company is administered and effectively managed in Romania. A company incorporated as a Romanian SRL — the vehicle covered in our SRL formation guide — is Romanian-resident by incorporation, so the certificate is largely a formality provided the company is current with its filings.
Where the certificate is destined for use abroad, the foreign authority may require it to be apostilled or otherwise legalised. Romania and its treaty partners are, in almost all relevant cases, parties to the Hague Apostille Convention, so a single apostille from the competent Romanian authority suffices; a handful of states require consular legalisation instead. Confirm the destination state's requirement before filing, because the apostille adds days to the timetable.
Processing time and validity
Unlike the residency determination — where ANAF has a -day window to notify the person of full or limited liability after the arrival questionnaire is filed — the certificate itself carries no long statutory clock. In practice a complete file is turned around by the tax office in a short number of working days, and SPV submission is faster than counter filing. Delays, when they happen, come from an incomplete residency file rather than from the certificate request as such.
On validity, two points matter. The certificate is issued for a defined period — normally the calendar year — and foreign payers generally treat it as evidence for that year only, requesting a fresh certificate each year the treaty relief continues. The original is what most foreign authorities want; some accept a certified copy, but the default expectation abroad is the original document, apostilled where required. Because practice on the exact acceptance window varies by destination state, confirm with the foreign payer or authority how recent a certificate they require before you request it.
Treat the certificate as an annual document. A payer applying a treaty rate this year will usually want a current-year certificate on file, not last year's.
Using the certificate: claiming treaty relief
The certificate earns its keep in two directions.
Presenting it to a foreign payer. A company in a treaty state paying you dividends, interest, royalties, or fees will, absent a certificate, withhold at its domestic rate. On receipt of a valid Romanian certificate, it applies the lower treaty rate — often materially lower, and in some cases zero. The certificate is the payer's authority to reduce withholding; without it, the payer has no basis to depart from domestic law, and you are left reclaiming the difference through a refund procedure that can take a year or more.
Presenting it to a former home tax authority. A founder who has genuinely relocated to Romania uses the certificate to demonstrate to the country they left that they are now resident elsewhere and should no longer be taxed there on worldwide income. This is the harder case, because the home authority has every incentive to keep you within its net. The certificate is necessary but not sufficient: where the home state disputes the move, the matter is resolved under the treaty tie-breaker, and the certificate is weighed alongside where your permanent home, family, and economic life actually sit. For EU relocations this is exactly the terrain our Germany exit-tax playbook and Netherlands BV relocation guide cover.
Note the direction of travel on the numbers. Since Romania's dividend withholding tax rose to % on personal tax and dividend guide January under Law 141/2025, most treaty rates now sit below the Romanian domestic rate rather than above it — the reverse of the position before . A non-resident receiving Romanian dividends increasingly needs their own home-state certificate to bring Romanian withholding down to the treaty rate. The mechanics of the % rate are set out in our personal tax and dividend guide.
Where it goes wrong
The certificate is administratively simple. The failures are upstream of it, in the residency it purports to prove:
- Requesting the certificate before the residency is real. A registered address and a certificate, with the founder still living and working at home, does not survive a foreign authority's scrutiny. The certificate then becomes evidence of an aggressive position rather than a defence of a sound one.
- Skipping the arrival questionnaire. The certificate presupposes a settled residency determination. If the questionnaire was never filed, ANAF has not formally recorded the status the certificate is meant to reflect, and the file stalls.
- Using last year's certificate. A payer applying a current-year treaty rate on the strength of a two-year-old certificate is exposed, and so are you.
- Ignoring the destination state's legalisation rule. A certificate that should have been apostilled, or consular-legalised, is rejected at the counter abroad and the relief is delayed.
Each of these is avoidable with sequencing: establish the residency, file the questionnaire, let ANAF confirm the status, then request the certificate for the specific treaty and year in which it will be used.
Frequently asked questions
Does the certificate make me a Romanian tax resident?
No. The certificate only evidences a residency that already exists under the substantive tests — domicile, permanent home, centre of vital interests, and the -day presence rule. It is issued after the status is settled, not to create it. If the underlying residency does not hold, the certificate does not fix that, and a foreign authority can look behind it.
Is the certificate the same as the arrival questionnaire?
No. The questionnaire (chestionar) establishes and registers your residency with ANAF on arrival; the certificate proves that settled residency to a third party abroad. You file the questionnaire to become resident and request the certificate to demonstrate that you already are. They serve opposite ends of the same process.
How long does it take to obtain?
The certificate itself has no long statutory processing clock and a complete file is typically issued within a short number of working days, faster through the Spațiul Privat Virtual than at the counter. Most delays come from an incomplete underlying residency file rather than from the certificate request.
How long is the certificate valid?
It is issued for a defined period, normally the calendar year, and foreign payers generally treat it as evidence for that year only. In practice you request a fresh certificate each year that treaty relief continues. Confirm with the foreign payer how current a certificate they require, since acceptance windows vary by state.
Do I need the original, and does it need an apostille?
Most foreign authorities want the original document. Where it is used abroad it usually needs a Hague apostille from the competent Romanian authority; a few states require consular legalisation instead. Confirm the destination state's requirement before filing, because legalisation adds time to the process.
Can a Romanian SRL obtain a certificate for the company itself?
Yes. A Romanian SRL is tax-resident by virtue of its incorporation and place of effective management, and can obtain a certificate to support treaty relief on cross-border payments it receives. The file is lighter than for individuals — the certificat constatator, the CUI, and current filings are usually enough.
