Services for your Estonian OÜ if you live in Spain
Irys Solutions OÜ provides comprehensive accounting and compliance services for your Estonian OÜ
when you live in Spain: company registration, monthly accounting support, VAT/OSS,, elección de
as well as tax and compliance risk management and risk control in relation to the Spanish tax authority and compliance departments.
You work online with clients in different countries; we make sure that invoicing through an Estonian company continues to fit your reality as a Spanish tax resident. We translate your day-to-day operations into a clear structure — OÜ + accounting + banks — so you spend less time on administration, receive fewer “urgent” emails, and have a well-organised, defensible setup if a bank or the tax authority takes a closer look at your case.
What we do for you in practice
We do not sell “empty shells” in Estonia. Our OÜ services are designed for people living in Spain who want to work with international clients without wasting time on accounting tasks or exposing themselves to unnecessary risks with the tax authority or banks.
In theory, everything looks easy: online registration, digital signatures, modern banks.
In practice, Spain is your tax residence, the tax authority receives more information than ever (automatic reporting, CRS, SII, European banks), and fintech banks ask you to justify everything.
As a result, a poorly configured OÜ can trigger alerts even if you are doing nothing wrong.
- OÜ structure design: Estonia as the home of your company, Spain as your tax residence — explained in plain language.
- OÜ registration and e-Residency: from application to an active company, with basic statutes and accounting policies defined.
- Monthly accounting and taxation: bookkeeping, VAT/OSS (the EU one-stop-shop regime for digital services)
and annual accounts filed on time — without you having to track the tax calendar every day. - Banks and fintech: selection between Wise Business, Revolut Business or LHV Bank based on your profile,
plus support with the
KYC/AML package (know-your-customer / anti-money-laundering). - Risk control: review of patterns that may attract attention from the tax authority or compliance analysts before a letter asking
to “clarify movements” appears.
What problems a specialised OÜ accounting firm saves you from
Running an Estonian company while living in Spain involves accounting, VAT/OSS, banks, compliance, Spanish tax filings and a logic that is very different from a Spanish SL.
With a clear system and a dedicated team behind you, you work calmly — without surprises.
Less time wasted
With an organised system, you focus on your work — we handle the rest.
Fewer “urgent” emails
We set things up so you don’t have to respond in panic mode.
Documentation ready if anyone asks
everything clean, structured and ready for reviews, checks or audits.
How tax authorities and banks see you (and why details matter)
Tax authorities and banks do not see “a friendly freelancer with an OÜ”. They see data: account movements, income patterns, tax filings, automatic cross-checks between reports and internal alert systems. And this analysis is becoming increasingly automated and strict.
- More data than ever: banking information, tax filings, e-invoicing and cross-checks with other authorities.
- Alert algorithms: income and expense patterns that do not match what is declared trigger internal flags.
- Extra scrutiny for foreign-company structures: an Estonian OÜ with a Spanish tax resident is often included in automatic review lists.
You do not need to “intend to do something wrong” to end up grouped with those who do.
A few accumulated red flags — unclear transfers, inconsistencies between declared income and account movements, or vague
answers to a bank — can be enough for your case to receive a higher level of attention.
If ending up on a red-flag list is not part of your plans, it is safer to design the structure carefully now than to have to explain
it in a hurry later.
Our job is to ensure that what you do in practice
is translated cleanly into the systems used by tax authorities and banks:
clear records, explainable payment flows and documentation prepared before anyone asks for it.

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.
Do you want to structure your OÜ properly and avoid issues later on?
We review your case, tell you whether an OÜ makes sense for you from Spain,
what should be adjusted, and how to get everything ready for banks, taxes and compliance.
A short, clear consultation — with no obligation.
