Why choose an OÜ? — objective advantages
An OÜ works well for professionals and teams with international clients. It is not “tax magic”, but modern, predictable EU operations.
- EU operations and banking: European IBAN and 100% online onboarding (Wise, Revolut, LHV). Digital signing via e-Residency.
- International invoicing: B2B invoicing in euros, VAT/OSS for digital services in the EU.
- Digital processes: electronic filings and reporting — no in-person appointments, no paperwork.
- Scalability and governance: multi-country partners, contractor agreements, dividends and B2B contracts.
- Reputation and compliance: pro-tech legal framework, documentation in English/Estonian accepted by partners.
When an OÜ Might Not Be Suitable
- Income and operations mainly based in Spain with local presence (potential PE risk).
- Need for payroll and employment under Spanish labour law.
- Suppliers or tenders that require a Spanish company (SL) or purely domestic VAT.
If your case fits better with autónomo or a Spanish SL, we will say so — no empty promises.

Autónomo vs OÜ — what works best in your case?
Practical points to decide based on income, clients and how you operate. In the consultation, we give you an honest verdict.
Autónomo (Spain)
- Registration and contributions: Fixed monthly social security fee (initial reduced rate, then full contribution).
- Taxation: Progressive personal income tax (IRPF); Spanish VAT filed quarterly.
- Invoicing: Simple for Spanish clients; intra-EU invoicing requires VIES registration.
- Payroll/Social security: Mandatory self-employment contributions (RETA).
- Scalability: Limited when hiring and when separating personal and business risk.
- Recommended if: You operate mainly in Spain, have low to medium ticket sizes, and only a few international B2B contracts.
OÜ (Estonia)
- Incorporation: 100% online with e-Residency; fast statutes and company registration.
- Taxation: Undistributed profits = 0% corporate tax in Estonia; dividends are taxed when distributed.
- VAT/OSS: Suitable for EU digital services and intra-EU B2B invoicing.
- EU banking: Wise, Revolut, LHV with KYC/AML; European IBAN.
- Team and contracts: Multi-country B2B contracts; better separation of risks and growth potential.
- Recommended if: You have international clients, medium to high ticket sizes, and need governance and scalability.
Note: Your tax residence remains Spain. We analyse PE/CFC risks as part of the Setup and double-taxation treaties to ensure the structure is compliant and defensible.

How much can you save with a properly structured OÜ?
Instead of guesses, you get a numerical estimate of:
your current structural costs, a scenario with an Estonian OÜ plus Irys accounting support,
administrative hours that could be freed up, and the level of risk in relation to the Spanish tax authority.
The calculator does not replace tax advice,
but it gives you
a quick, easy-to-understand snapshot to help you to decide whether it is worth
reviewing your case in detail.
