Overview: Romanian Entrepreneurs in the US Market
Bucharest and Cluj-Napoca have thriving tech scenes with companies like UiPath (Romanian-founded, now US HQ), TypingDNA, and FintechOS. Romania's micro-enterprise tax (1% on revenue) is one of Europe's most attractive.
However, operating a US business entity from Romania comes with specific IRS obligations that many entrepreneurs initially overlook. The US-Romania tax treaty provides important benefits, but understanding how to properly leverage these while maintaining compliance is essential.
Key Takeaway
Romanian citizens and residents owning US LLCs or corporations must file US tax returns annually, even if the business has no US income or operates at a loss. The US-Romania tax treaty can significantly reduce your tax burden when properly applied.
US Tax Requirements for Romanian Business Owners
As a Romanian entrepreneur with a US business entity, your tax obligations depend on your company structure, income sources, and whether you qualify as a US tax resident.
Form 5472 Requirements
Form 5472 (Information Return of a 25% Foreign-Owned U.S. Corporation) must be filed annually by any US corporation or LLC that is at least 25% foreign-owned and has "reportable transactions" with foreign related parties.
For Romanian entrepreneurs, reportable transactions typically include:
- Capital contributions: Any money transferred to your US company
- Loans: Funds borrowed from or lent to the company
- Service payments: Fees for services between you and the company
- Rent or royalties: Payments for intellectual property or equipment
- Sales of goods: Any inventory or assets sold between related parties
Even a single-member LLC with no business activity must file Form 5472 if there was any transaction between you (the foreign owner) and the LLC during the tax year.
Important: Formation Services Don't Handle Compliance
If you formed your US LLC through Stripe Atlas, Firstbase, doola, or similar services, you still have Form 5472 filing obligations. These services help with formation but typically don't handle ongoing IRS compliance.
Form 1120 Requirements
Foreign-owned disregarded entities (single-member LLCs) must file a pro-forma Form 1120 along with Form 5472. C-Corporations and LLCs electing corporate taxation must also file Form 1120 annually, even with zero income.
ITIN Application Process
An Individual Taxpayer Identification Number (ITIN) is required for Romanian citizens who need to file US tax returns but don't qualify for a Social Security Number.
| Feature | CNP (Cod Numeric Personal) | US ITIN |
|---|---|---|
| Purpose | Romania tax identification | US tax identification for non-residents |
| Format | 13 digits | 9 digits (9XX-XX-XXXX) |
| Issued by | ANAF (Agenția Națională de Administrare Fiscală) | Internal Revenue Service (IRS) |
| Processing time | Varies | 7-11 weeks typically |
Pro Tip: Passport Verification
Rather than sending your original passport to the IRS, use a Certifying Acceptance Agent (CAA) who can verify your identity documents. This is faster, safer, and doesn't require you to be without your passport for weeks.
US-Romania Tax Treaty Benefits
The US-Romania tax treaty provides reduced withholding rates on certain types of income, offering significant savings compared to the standard 30% rate.
| Income Type | Standard US Rate | Treaty Rate |
|---|---|---|
| Dividends (substantial holdings ≥10%) | 30% | 10% |
| Dividends (portfolio) | 30% | 10% |
| Interest | 30% | 10% |
| Royalties | 30% | 10% |
Key treaty benefits for Romanian entrepreneurs:
- Reduced dividend withholding: 10% for substantial holdings, 10% for portfolio dividends (vs 30% standard)
- Reduced withholding on interest: 10% instead of the standard 30%
- Reduced withholding on royalties: 10% instead of 30%
- Business profits exemption: Romanian residents generally aren't taxed on US business profits without a US permanent establishment
Claiming Treaty Benefits
To claim treaty benefits, provide Form W-8BEN (individuals) or W-8BEN-E (entities) to the payer, referencing the US-Romania treaty. Incomplete forms can result in full 30% withholding.
Romania Tax Considerations
Romanian entrepreneurs with US entities must also consider their domestic tax obligations:
- Corporate tax rate: 16% (1% micro-enterprise)
- 1% micro-enterprise tax: 1% micro-enterprise tax on revenue (for companies under €500K)
- 16% standard CIT: 16% standard CIT
- 10% flat personal: 10% flat personal income tax
- Worldwide taxation for: Worldwide taxation for residents
- CFC rules under: CFC rules under EU ATAD
- ANAF reporting of: ANAF reporting of foreign assets required.
Important Tax Deadlines
| Deadline | Filing Requirement | Notes |
|---|---|---|
| April 15, 2025 | Form 1120 & 5472 | For calendar year corporations |
| June 15, 2025 | Extended deadline for foreign filers | Automatic 2-month extension |
| March 25 | Romania tax return | March 25 (individual income, Declarația Unică) |
| September 15, 2025 | Extended US returns | With Form 7004 filed |
Automatic Extension Available
Foreign-owned corporations automatically receive a 2-month extension (to June 15) for filing. You can request an additional extension to September 15 by filing Form 7004 before April 15. However, any tax owed is still due by April 15.
Penalties for Non-Compliance
- Form 5472 penalty: $25,000 per form, per year for failure to file or filing an incomplete return
- Continued failure: Additional $25,000 for each 30-day period of non-compliance after IRS notice
- Form 1120 penalties: 5% of unpaid tax per month, up to 25% maximum
- Accuracy-related penalties: 20% of any underpayment due to negligence
Penalty Example
A Romanian entrepreneur who fails to file Form 5472 for three years could face $75,000 in penalties ($25,000 x 3 years), regardless of whether the business made any money.
State Tax Considerations
| State | State Income Tax | Annual Fee | Key Benefits |
|---|---|---|---|
| Delaware | None for out-of-state | $300/year | Business-friendly courts, established case law |
| Wyoming | None | $60/year | Lowest fees, strong privacy |
| New Mexico | None for out-of-state | $0/year | No annual report |

- Missing the initial filing: Your first tax return is due even if you formed your LLC late in the year
- Not keeping transaction records: You must document all transactions between yourself and your US company
- Assuming "no income = no filing": Zero-income companies still have filing obligations
- Not claiming treaty benefits: Many Romanian entrepreneurs pay more withholding tax than necessary
- Forgetting state requirements: Annual reports and franchise taxes vary by state and have separate deadlines
- Not reporting locally: Failing to report US income on your Romania tax return
- Incorrect W-8BEN forms: Filing improper forms can result in unexpected withholding
