Romania and the 183-day rule: the tax residency trap every expat must know

Romania's Fiscal Code (Art. 7) defines tax residency based on physical presence: if you spend more than 183 days in Romania during any consecutive 12-month period that starts or ends in the calendar year, you become a Romanian tax resident. This applies regardless of your nationality, visa type, or whether you intended to stay long-term.

Who does this affect?

Digital nomads on the Romanian Digital Nomad Visa

Romania's digital nomad visa (launched 2021) allows stays of up to 12 months, renewable. Many nomads cross the 183-day threshold without realising it — especially those who renew their visa or make Romania a base. Once you cross the threshold, you may owe Romanian income tax on your global income for that tax year.

Expats relocating to Romania

If you have moved to Romania for work, retirement, or lifestyle reasons, the 183-day threshold is typically reached within the first partial year. This triggers a legal obligation to register with ANAF as a tax resident within 30 days.

Foreign company directors and employees

Directors of Romanian-registered companies who travel to Romania regularly, or employees of Romanian subsidiaries working primarily in Romania, may trigger residency depending on the frequency and nature of their presence.

Romanians living abroad with Romanian property or companies

Romanian nationals who maintain a Romanian domicile, own property in Romania, or hold a stake in a Romanian company may have ongoing ANAF filing obligations even while living full-time abroad.

The 30-day registration window

Once you become a Romanian tax resident, you have 30 days to register with ANAF as a natural person. This is done via Form 030 (Cerere de înregistrare fiscală a contribuabililor persoane fizice). Missing this deadline results in fines starting at 500 RON and can trigger an ANAF audit of your global income.

Double taxation treaties

Romania has signed double taxation avoidance treaties with over 90 countries, including all EU member states, the United States, the United Kingdom, Canada, and most of Europe. This means you typically will not pay tax twice on the same income — but you must still register, declare, and claim treaty relief. The filing obligation and the tax obligation are separate: failing to file even when you owe nothing is still a legal breach.

Your ANAF SPV inbox as the connection point

Once registered with ANAF, many important notices arrive in your SPV (Spațiu Privat Virtual) secure mailbox. Tax assessments, non-filing notifications, payment demands, and enforcement documents are commonly delivered there, generally in Romanian.

For foreign residents, this creates a real compliance risk. A non-filing notification that sits unread for 60 days can automatically become a penalty notice. A payment demand left unresponded can escalate to enforcement proceedings. Romanian law does not recognise "I could not read the Romanian document" as a valid defence.

Practical checklist for new Romanian tax residents

• Register with ANAF within 30 days of meeting the 183-day threshold (Form 030)
• Set up your SPV account — requires a certSIGN or DigiSign digital certificate on a USB token
• File your annual income declaration (Form D212) by 25 May of the following calendar year
• Gather documentation of your income from all countries for the relevant tax year
• Check which double taxation treaty applies to your main income source and home country
• Consider a Romanian accountant for the first filing year; afterwards FiscAlert keeps you informed of new obligations

Frequently asked questions

Do I count calendar days or consecutive days?

Days present in Romania during any 12-month period — not necessarily a single calendar year. Partial days count as full days. The window rolls forward, so the count resets with each new 12-month window, not at the start of each January.

What if I leave before 183 days?

If you depart before crossing the threshold and do not have a permanent domicile registered in Romania, you generally do not become a Romanian tax resident for that period. However, if your permanent address (domiciliu) is registered in Romania, you may be treated as a resident regardless of the day count.

I already pay tax in my home country. Do I still need to register with ANAF?

Possibly yes. Double taxation treaties eliminate double payment, but they do not eliminate the registration and filing obligation. You must register, file, and claim treaty relief. Failure to file when required carries fines that are independent of whether any tax is ultimately owed.

How do I connect my SPV inbox to FiscAlert?

You need a certSIGN or DigiSign USB token — the same one you use to log in to the ANAF portal. FiscAlert Connect (a small Windows background application) uses the token to read your SPV inbox and send documents to your FiscAlert account. Setup takes around 10 minutes.
