The choice of where to incorporate a business can have a far larger impact on cash flow than the headline corporate tax rate. A recent client case illustrates how payment‑processing fees, foreign‑exchange (FX) costs, and other operational expenses can outweigh a nominally “zero‑tax” jurisdiction.
Tax rates versus effective cost
| Jurisdiction | Corporate tax | Dividend withholding | Approx. effective tax* |
|---|---|---|---|
| United States (LLC) | 0 % | – | 0 % |
| Romania (SRL) | 1 % of gross revenue | 5 % on dividends | ~7 % (1 % + 5 % ≈ 6 %‑7 %) |
*Effective tax is calculated on revenue rather than profit, assuming a 55 % margin in the example.
Hidden costs that shift the balance
-
Payment‑processing fees
- US‑based processors: ~1.9 % of gross transaction value.
- Romanian processors: ~2.9 % of gross transaction value.
The 1 % difference is applied to revenue, not profit, so with a 55 % margin it translates to an additional ~2 % effective tax.
-
Foreign‑transaction surcharge
When the US LLC processes payments in euros, the processor adds a ~1 % foreign‑transaction fee. This again doubles on revenue, raising the effective cost by another ~2 %. -
Currency conversion (EUR → USD)
Converting euros to US dollars typically costs 1 %‑2.5 % of the amount. Using a conservative 1 % estimate adds another ~2 % effective tax (percentage of revenue). -
Re‑conversion (USD → EUR) for expenses
Spending the proceeds back in euros incurs a second conversion fee, again roughly 1 %, pushing the effective cost to about 8 % over the baseline.
Result: Although the US LLC has a zero corporate tax rate, the cumulative impact of processing, foreign‑transaction, and FX fees can raise the overall cost to ~8 % of revenue, surpassing the Romanian company’s ~7 % effective tax burden.
Other variables to weigh
- Currency of invoicing and spending – Aligning the functional currency of the business with the jurisdiction’s native currency reduces conversion steps.
- Staff and payroll expenses – Local labor costs, social‑security contributions, and benefits differ markedly between countries.
- Office and overhead – Rental rates, utilities, and ancillary services can be substantially cheaper in some regions.
- Banking and reputation – Access to reliable banking partners and the perceived credibility of the jurisdiction affect client trust and financing options.
- Regulatory risk – Consider the likelihood of political or legal changes that could affect the ability to operate or repatriate profits.
- Customer location – Proximity to the primary market can lower payment‑processing fees and reduce latency in settlements.
Practical decision framework
- Map revenue flow – Identify the currency in which you invoice clients and the currency needed for expenses.
- Calculate transaction costs – Sum processor fees, foreign‑transaction surcharges, and FX spreads for each jurisdiction.
- Add statutory taxes – Include corporate tax, dividend withholding, and any other mandatory levies.
- Factor operational overhead – Estimate staff, office, and compliance costs.
- Assess risk and reputation – Evaluate legal stability, banking access, and brand perception.
- Compare total effective cost – Express all items as a percentage of revenue to see the true cost of each structure.
Bottom line
When the bulk of a business’s income is earned in euros (or any non‑USD currency) and expenses are also in that currency, the transaction and FX fees associated with a US‑based entity can erode the tax advantage. In such scenarios, a jurisdiction like Romania, despite a modest corporate tax rate, may deliver a lower overall cost of doing business.
Choosing a jurisdiction should therefore prioritize total cash‑flow efficiency—including taxes, processing fees, currency conversion, and operational expenses—rather than focusing solely on headline tax rates.
