OÜ Accounting and Tax Services in Estonia for Residents of Spain
We combine OÜ registration, accounting support,VAT/OSS and tax obligations considering your status as a Spanish resident into a clear and consistent action plan.
Everything is explained in simple terms, with a clear understanding of deadlines and obligations.
In practice, there are always two sides that need to be synchronized: what the OÜ company in Estonia must do and what you are required to declare as an individual in Spain.
We structure both levels so that the setup is logical, sustainable, and clear to tax authorities and banks.
What we do in practice: monthly accounting, VAT/OSS, and annual reporting
We clearly separate what relates to Estonia (the OÜ company) and what relates to Spain (you as a resident and participant).
Simply put: one is the company’s money, the other is your personal funds.

Based on this, we determine which taxes apply to an OÜ structure and which ones apply to you as a tax resident of Spain.

Tax Overview: Your OÜ in Estonia and Your Status as a Spanish Resident
In the end, you get a clear scheme showing which taxes the OÜ company pays in Estonia and what obligations arise for you as a Spanish tax resident.
The goal is for you to make decisions with a complete view of the whole picture.
Corporate Tax in Estonia
In Estonia, undistributed profits may be taxed at a rate of 0 %.
The tax arises at the moment the company distributes dividends or makes certain payments treated as profit distribution.
Simply put: as long as funds remain in the OÜ and are used for business development, the tax burden in Estonia can be low.
When profits are distributed, Estonian tax applies, after which the tax impact in Spain is analyzed.
VAT/OSS and International Invoicing
We look at exactly what you sell and to whom. B2B Invoices to companies in the EU are often issued without VAT under the reverse charge mechanism.
Digital Services B2C may require the application of a regime OSS.
Sales to clients in Spain may require Spanish VAT, even if the company is registered in Estonia.
The key is to have clear rules, avoid mixing different scenarios, and be able to justify every issued invoice.
Your Personal Taxes in Spain
As a Spanish tax resident, you are required to declare everything you receive from your OÜ: dividends, potential salaries, and other taxable payments.
In practice, we separate what stays at the company level and what becomes your personal income to avoid confusion and unpleasant surprises during audits.
Legality, PE, and CFC — When an OÜ Works and When It Can Become a Problem
An OÜ can work well for international activities, but it is not a ‘magic solution’ without obligations.
We explain in clear, straightforward language when an OÜ is treated as a regular foreign company and when the risk of permanent establishment (PE) or a controlled foreign company (CFC) arises.
Healthy Scenario: OÜ as a Regular Foreign Company
- The activity is clearly online or international,with no office or team in Spain.
- Clients are spread across multiple countries, invoicing is documented, and there are B2B contracts in place.”
- Accounting is handled on time, annual reports are filed, and documents are stored systematically.
- A clear method of paying yourself: regular dividends or a predefined compensation policy.
- Business management can be explained to banks and tax authorities in a logical and consistent way.
High-Risk Scenario: PE or CFC Without Proper Setup
- The actual business activity is carried out almost entirely in Spain, despite the company being registered in Estonia.
- There is an office, team, or key resources in Spain that are not properly reflected in the company structure.
- High revenues without clear contracts or a straightforward explanation of the business model.
- The company appears as an ‘empty shell’ with no real operational activity in Estonia.
- There is no alignment between the OÜ accounting and personal tax declarations in Spain.
Our goal is to ensure the structure is defensible with banks and tax authorities.
If we see that a Spanish SL or another combination of structures makes more sense in your case, we tell you this from the very beginning.
What OÜ Accounting in Estonia Includes: Monthly Accounting, VAT/OSS, and Annual Reporting
The goal is so you don’t have to worry each month about which forms to file or which documents are missing.
We set up OÜ accounting with clear deadlines and a well-defined division of tasks, ensuring everything is done on time and without unnecessary stress.
Monthly Accounting and VAT Control
We track income and expenses, perform bank reconciliations, and prepare calculations. VAT/OSS — if needed.
If something doesn’t align with your business model, we flag it in advance, before any issues arise.
In practice, this means that every month you understand how the company is doing, which invoices have been accounted for, and what obligations lie ahead.
Annual Reporting and Documentation
We prepare annual reports for the OÜ and ensure that all necessary documentation is properly collected and archived:
invoices, contracts, bank statements, and supporting documents.
This simplifies both audits in Estonia and any potential inquiries from Spanish tax authorities, banks, and fintech platforms.
Coordination with Your Personal Tax Situation
We ‘ground’ the company’s numbers into your personal tax picture: what portion can be distributed as dividends and what remains within the company.
and what impact this has on your tax declaration in Spain.
The idea is for the company to have its own clear logic, while your personal tax burden naturally follows — rather than resulting from improvisation.
Who Can Benefit from This OÜ Tax Structure
An OÜ isn’t for everyone, and the benefits vary depending on the situation.
La OÜ registration, accounting support, They make sense when the structure honestly reflects the real operations of the business.
- IT freelancers, and specialists in design, marketing, and consulting with clients across different countries.
- Small teams (2–5 people) working B2B with companies in the EU and beyond.
- SaaS models and digital projects with regular revenue and a need to separate personal risks from the business.
- Cases where a company needs a stable banking infrastructure in the EU and transparent relationships with partners and investors.
When an OÜ Might Not Be Suitable
- Operations are mainly local in Spain, with clients and activities almost entirely within the country.
- The business heavily depends on a physical presence (stores, construction, in-person services).
- Situations where it is difficult to properly document activities or the origin of funds.
If we see that a different structure is more suitable for your case, we will say so directly, without using evasive language
Our goal is to ensure that the tax model reflects and supports the actual business reality, rather than distorting it.
The accounting of an OÜ changes significantly if the owner lives in Spain.
