Romania isn’t typically on the radar for those of us seeking extreme fiscal optimization. It’s not the Caymans. It’s not even Estonia. But it occupies a curious middle ground in Eastern Europe—low enough rates to keep businesses marginally interested, complex enough to trip you up if you’re not paying attention. And in 2026, the corporate tax landscape has gotten… messier.
I’m diving into Romania’s corporate income tax (CIT) rules because if you’re operating here—or considering it—you need to know exactly what you’re walking into. The headline rate is straightforward. The fine print? Not so much.
The Baseline: 16% Flat Corporate Tax
Romania applies a flat 16% corporate income tax on profit. Not on revenue. On profit.
That’s the good news. Flat rates are predictable. You calculate your taxable income, multiply by 0.16, and you have your base liability. No progressive brackets. No sudden jumps when you cross a threshold. Just 16%.
For context, that’s competitive within the EU. Germany’s hitting companies at 30%+ when you include trade tax. Italy’s dancing around 24%. Romania’s base rate is genuinely attractive if you’re comparing apples to apples.
But here’s where I need you to slow down and read carefully: that 16% is just the starting point.
The Surtaxes Nobody Mentions Upfront
Romania has layered on a series of additional taxes and minimum thresholds that can completely change your effective rate. Let me break them down.
Construction Tax (1%)
Effective January 1, 2025, if you own constructions in Romania—buildings, structures, anything that isn’t already subject to the local building tax—you owe an additional 1% tax on the value of those constructions.
This isn’t a profit tax. It’s an asset tax. Even if your company is bleeding cash, you owe it. If you’re holding significant real estate as part of your corporate structure, this adds up fast.
Pillar 2: The 15% Minimum for Large Groups
Starting January 1, 2024, Romania implemented the OECD Pillar 2 Directive. If your multinational enterprise (MNE) group or large domestic group has consolidated annual revenues of at least €750 million (approximately $810 million USD) in at least two of the four prior financial years, you’re subject to a minimum effective tax rate of 15%.
Romania’s base rate is already 16%, so this shouldn’t bite you directly in Romania. But it matters for global structuring. If your group is paying less than 15% effective tax globally, Romania can impose a top-up tax to bring you to that floor. This is the new global minimum tax regime, and Romania is playing along.
For smaller businesses, this doesn’t apply. But if you’re part of a large international structure, you need to model this carefully.
Minimum Turnover Tax (IMCA)
Here’s where things get punitive.
If your company’s turnover exceeds €50 million (roughly $54 million USD) and your calculated CIT is lower than the Minimum Turnover Tax (IMCA), you must pay CIT at the IMCA level instead.
The exact rate isn’t specified in the official documents I have access to, which is frustrating. But the principle is clear: if you’re a high-revenue, low-profit company—whether through legitimate business losses, aggressive deductions, or transfer pricing gymnastics—Romania wants to ensure it gets something from you based on turnover, not just profit.
This is a direct attack on profit-shifting strategies. I’m not here to moralize, but I am here to warn you: if you’re running a €60 million revenue company with paper-thin margins, you could end up paying more tax than your profit would suggest.
Specific Turnover Tax for Oil & Gas (ICAS)
If you’re in the oil and gas sector with turnover exceeding €50 million ($54 million USD), you owe an additional specific turnover tax (ICAS) on top of your regular CIT.
Again, the rate isn’t publicly detailed in the base documentation. But this is Romania’s way of extracting more from energy companies during profitable periods. Expect this to be material if you’re in extraction or refining.
Credit Institution Turnover Tax
Banks and credit institutions now face a separate turnover tax in addition to CIT. The rate? Not specified in the documents I’ve reviewed.
If you’re running a financial institution in Romania, you need to engage local counsel or a Big 4 firm immediately. This is not a DIY situation.
What This Means for Your Effective Rate
Let’s summarize the potential tax load in a clear table:
| Tax Type | Rate | Trigger Condition |
|---|---|---|
| Standard Corporate Income Tax | 16% | On taxable profit |
| Construction Tax | 1% | On value of constructions (non-building-taxed assets) |
| Pillar 2 Minimum Tax | 15% | MNE/large groups with €750M+ revenue (≈$810M) |
| Minimum Turnover Tax (IMCA) | Variable* | If turnover > €50M (≈$54M) and CIT < IMCA |
| Oil & Gas Turnover Tax (ICAS) | Variable* | If turnover > €50M (≈$54M) |
| Credit Institution Turnover Tax | Variable* | Financial institutions |
*Rate not publicly specified in available documentation. Consult local tax authority or advisor.
The Opacity Problem
Notice how many of those surtaxes have unspecified rates? That’s not an accident.
Romania’s tax administration—ANAF—doesn’t always publish granular rate schedules in English or in easily accessible formats. You’ll find the headline 16% everywhere. The construction tax rate is clear. But IMCA, ICAS, and the credit institution tax? You’re digging through Romanian-language ministerial orders or relying on advisors who may or may not be current.
This is a transparency issue. And it’s a risk.
I am constantly auditing jurisdictions like Romania. If you have recent official documentation—especially on IMCA rates, ICAS rates, or the credit institution turnover tax—please send me an email or check this page again later. I update my database regularly, and I rely on practitioners and insiders to fill gaps.
Practical Takeaways
If you’re a small to mid-sized company with revenue under €50 million ($54 million USD) and no significant real estate holdings, Romania’s 16% flat CIT is genuinely competitive. You’re largely shielded from the surtaxes.
If you’re above that €50 million threshold, or if you’re in oil, gas, or banking, your effective rate is not 16%. It could be significantly higher depending on your profit margins and asset mix. You need to model this with a local advisor who understands the current enforcement environment.
If you’re part of a multinational group with €750 million+ revenue, Pillar 2 applies. Romania is enforcing this. Your global tax planning must account for the 15% floor.
And if you own constructions? Budget for that 1%. It’s small, but it’s recurring and unavoidable.
Final Word
Romania isn’t a tax haven. It never claimed to be. But it’s not a high-tax nightmare either—provided you stay below the surtax thresholds and keep your structure clean.
The 16% headline rate is real. Just don’t mistake it for the whole story. I’ve seen too many operators get blindsided by minimum turnover taxes or sector-specific levies because they skimmed the overview and skipped the footnotes.
Do your homework. Get local counsel. And if you’re structuring across multiple jurisdictions, make sure Romania’s surtaxes don’t accidentally make it the most expensive link in your chain.
