Romania Cross-Border Tax Guide 2026

Residency — 183-Day Rule

Romania determines tax residency based on physical presence. An individual is resident if present in Romania for 183 days or more in any 12-month period (or calendar year, per domestic rules). Residents are taxed on worldwide income. Non-residents are taxed only on Romania-source income. The 183-day test applies to physical presence for any purpose (work, study, tourism). Days of arrival and departure are counted. Romania also uses the center of vital interests test (discussed in the Tax Residency Guide).

Worldwide Income for Residents

Romanian tax residents are subject to IIT (10%) on their worldwide income, including employment income, business income, investment income, rental income, and capital gains from both Romanian and foreign sources. Foreign income must be declared in the annual tax return. Double taxation relief is available through Romania's extensive treaty network (90+ countries) and the unilateral foreign tax credit. Foreign-source income is reported in the same tax return as Romanian-source income, with separate schedules for foreign income and foreign tax paid.

Source-Only Taxation for Non-Residents

Non-residents are taxed only on Romania-source income, including: employment income for work physically performed in Romania (unless covered by the 183-day rule under a DTA), income from immovable property in Romania, business income from a permanent establishment in Romania, dividends, interest, royalties from Romanian sources, and capital gains from Romanian real estate or shares in Romanian companies. Withholding tax (WHT) is the main collection mechanism for passive income paid to non-residents. Rates are often reduced under DTAs.

Treaty Network — 90+ Countries

Romania has one of the most extensive tax treaty networks in Europe with 90+ countries. Key treaty partners include all EU member states, USA, Canada, UK, Japan, China, India, Turkey, UAE, and most OECD countries. Treaties generally follow the OECD Model Convention. Typical reduced WHT rates under treaties: dividends 5-15%, interest 3-10%, royalties 3-15%. Romania has signed the Multilateral Instrument (MLI) to prevent treaty abuse and has been active in tax information exchange. The extensive network makes Romania attractive for cross-border business and investment.

Foreign Tax Credit (Unilateral)

Romania provides a unilateral foreign tax credit for income taxes paid abroad, even in the absence of a tax treaty. The credit is limited to the Romanian tax attributable to the foreign income (per-country limitation). Foreign tax credits are claimed in the annual income tax return. Documentation requirements include proof of foreign tax payment and evidence of the foreign income. The unilateral credit mechanism is particularly important for residents with income from non-treaty countries.

Special Tax Exemptions

Romania offers targeted tax exemptions for specific sectors: IT developers — 0% IIT on employment income (exemption for software developers meeting specific criteria, valid until 2028+). Construction workers — reduced IIT and reduced social contributions (applicable to workers in the construction sector). Agricultural workers — reduced social contribution rates for seasonal agricultural workers. Micro-enterprises — small businesses with revenue below EUR 500,000 and 1-9 employees can opt for the micro-enterprise tax regime (1% or 3% of revenue instead of corporate income tax). These exemptions have made Romania competitive for IT and other sectors.

FAQs

How do I claim treaty benefits in Romania?

To claim reduced WHT rates under a tax treaty, the non-resident must provide a certificate of tax residency from their country of residence (typically form RO-RO or equivalent) and complete a self-declaration. The Romanian payer then applies the treaty rate at source. Claims for refund of excess WHT can be made to ANAF.

Are foreign pensions taxable in Romania?

Foreign pensions received by a Romanian resident are generally taxable as income. However, specific treaty provisions may allocate taxing rights to the source country. Under most DTAs, private pensions are taxable only in the country of residence, while government pensions may be taxable in the source country.

What is the IT developer tax exemption?

The IT developer exemption provides 0% IIT on employment income for software developers who meet specific criteria: holding a relevant degree or certification, working in software development/IT, and employed by a registered IT company. The exemption was extended through 2028 and is one of the most generous IT tax incentives in the EU.
