Self-employed tax & accounting services in Spain
Starting as self-employed (autónomo) in Spain can feel overwhelming, especially if you come from a country with a different system. You can search online or use AI tools, but it is still difficult to fully understand how everything connects in practice.
Very quickly, you find yourself navigating unfamiliar concepts: Digital Certificate, tax forms, ROI registration, intra-community VAT, Social Security contribution bases, quarterly filings and more. Even if you speak Spanish, the terminology can be confusing. And if you don’t, translations are often incomplete or misleading.
You know you should verify information through official sources, yet you may not even be familiar with the names of the institutions involved, such as the Spanish Tax Agency or the Social Security Administration. Even something as basic as identifying the correct official website can be frustrating, as multiple portals exist for different procedures.
At In English Gestoría, our role is simple: we take full responsibility for your tax and accounting obligations in Spain, so you can focus on building your business with clarity and confidence.
From the initial orientation call to the onboarding session, we ensure you clearly understand your obligations, how they will be managed, and what to expect throughout the year. Our structured, fully remote model — supported by modern digital tools and professional communication in English — allows you to operate in Spain without uncertainty, administrative stress or unpleasant surprises.
Specialist tax support for self-employed expats, freelancers and digital nomads
We specialize in supporting self-employed expats who invoice internationally and require structured, fully compliant tax and accounting support in Spain. Our focus is on freelancers and digital nomads — particularly those working in marketing, technology and other remote-based industries — who often have clients both inside and outside Spain and need clarity, efficiency and reliability in their tax setup.
Within our team, we work with professionals who are not only specialists in self-employed taxation, but who also have extensive experience supporting European freelancers and digital nomads. Most of these clients typically have two or three customers outside Spain, some within the European Union and others outside it. In both cases, it is essential that the self-employed setup is handled correctly from the beginning. For example, those with clients in the EU must register in the ROI (Register of Intra-Community Operators) in order to issue invoices without VAT when applicable. While clients do not need to understand every technical detail, we believe it is important that, during the onboarding session, they gain a clear understanding of which tax forms will be filed, what each one represents, and why they are required.
Another common frustration our clients express when they come to us is the difficulty in communicating with their tax advisors. Although many professionals may speak intermediate English, it is often not sufficient to discuss technical aspects of finance and taxation with clarity and confidence. For this reason, we ensure that all our interactions are conducted entirely in English, unless the client feels fully comfortable communicating in Spanish.
In an increasingly fast-paced world, freelancers and digital nomads are used to dynamic work environments that prioritize efficiency and time optimization. For this reason, we have built a structured and fully remote model supported by modern digital tools that simplify processes which might otherwise seem complex. Instead of relying on endless emails and phone calls, our clients can upload documents through a centralized platform, keeping their accounting and tax obligations organized, transparent and easy to manage.
Starting as self-employed in Spain
How to register as self-employed
Although Spain has made significant progress in allowing self-employed registrations to be completed online, and even though AI tools can explain the steps and help you organise the process to some extent, the reality is that becoming autónomo still involves a considerable level of technical complexity.
For this reason, it is often advisable to delegate the process to a qualified professional — a specialised tax advisor. Incorrect configuration at this stage can lead to penalties, incorrect quarterly filings, or even the loss of important tax benefits.
According to the Spanish Tax Agency, any individual who intends to carry out an economic activity in Spain must formally register before starting their activity and comply with ongoing tax reporting obligations.
AI tools can help you identify the basic requirements and documentation you will need:
-
A valid NIE authorising you to work in Spain
-
A registered address in Spain
-
A Spanish bank account (for tax direct debits)
-
A digital certificate (essential for dealing with Spanish public authorities online)
-
A Social Security number
Once you formally appoint us as your tax advisors, the first step we take is to arrange your appointment to obtain your digital certificate.
After you receive it, we guide you step by step to complete your registration with both the Spanish Tax Agency and the Social Security authorities. From that moment onwards, you are no longer navigating the Spanish system alone — we handle the process for you and ensure everything is correctly configured from day one.
When registering with the Spanish Tax Agency, one of the most important decisions is choosing the correct tax regime:
-
Direct assessment (estimación directa) – tax based on actual profits
-
Objective assessment (módulos) – tax based on fixed parameters
In practice, most freelancers and digital nomads fall under the direct assessment regime, as it reflects real income and offers greater flexibility.
Social Security registration
Another key step is registering with the Spanish Social Security system through the official Import@ss portal using your digital certificate.
Self-employed individuals must enrol in the RETA (Special Regime for Self-Employed Workers) and choose a contribution base aligned with their expected income.
Although straightforward for experienced advisors, it can be confusing and time-consuming for individuals unfamiliar with the Spanish administrative system.
Choosing the right tax regime
At this stage, we configure important elements such as your Social Security contribution base. Under the income-based contribution system, your declared income determines both your monthly payments and the benefits you would receive in case of sick leave or other contingencies.
In most cases, the minimum contribution base is selected, depending on projected income and personal circumstances. We also choose the mutual insurance company (mutua) responsible for managing medical leave and benefits.
Flat rate and reductions
Under the flat rate scheme regulated by the Spanish Social Security system, eligible self-employed individuals may benefit from reduced contributions during their first year of activity. We make sure your registration is set up correctly so that you can benefit from this reduction (currently around €87 per month during the first year, subject to eligibility and current regulations).
From the second year onwards, contributions are adjusted according to your income level, starting from the minimum contribution established under current legislation.
Our accounting and compliance services for self-employed (autónomos)
Once you sign a collaboration agreement with us, you can forget about your accounting and tax obligations in Spain — we take care of everything. From the very beginning, however, we clearly explain each of your obligations and how we will ensure they are properly fulfilled on your behalf.
Bookkeeping & Expense Management
As mentioned earlier, it is very important for us that our clients understand the obligations we manage for them. In Spain, self-employed individuals are not required to keep complex accounting records. However, they must maintain a monthly record of income and expenses through official purchase and sales ledgers.
We prepare these records using a modern ERP system called Holded. During the onboarding session, we teach our clients how to issue invoices through the platform. Once properly configured, all sales are automatically recorded in the sales ledger.
Regarding deductible expenses, clients also receive guidance during onboarding about which expenses they can deduct in their specific situation for quarterly income tax filings. We also explain additional deductions that may apply when filing the annual income tax return. This is particularly important during the first year of activity, when certain tax reductions — such as the 20% reduction on net income for new self-employed individuals — may apply and require proper planning.
VAT & Income Tax Filing
Most of our self-employed clients are marketing and technology consultants from Europe, the United States and other countries, typically working with two or three clients based outside Spain. Many believe that because their services are VAT-exempt when invoicing foreign clients, they have no VAT-related obligations in Spain. This is not correct.
Even if no VAT is charged, invoices must include specific legal references. In addition, quarterly VAT returns must still be filed, even if they are only informative. Annual VAT summaries are also required, as well as intra-community transaction reports if clients are located within the European Union.
Beyond VAT filings — and often more relevant from a financial perspective — are the quarterly income tax payments (IRPF). These are advance payments towards the annual income tax.
Since most foreign clients do not withhold Spanish income tax, self-employed professionals must make these advance payments themselves. Proper calculation and forecasting are essential to avoid cash-flow stress at the end of the year. We continuously monitor your figures so there are no unexpected tax bills.
Annual Accounts & Tax Planning
On an annual basis, self-employed individuals must file a personal income tax return. This involves declaring worldwide income, deducting allowable business expenses, and applying the progressive Spanish income tax rates to the resulting net profit. Quarterly payments made during the year are deducted from the final tax liability, along with any additional deductions permitted by law.
It is essential to work with an advisor who understands which deductions can legitimately be applied and which cannot. All our associated advisors are senior professionals with more than ten years of experience, particularly working with digital nomads and freelancers.
During onboarding, clients may also request an income tax simulation. This allows them to anticipate quarterly payments and the final annual tax liability, helping them plan cash flow more effectively throughout the year. Our objective is not only compliance, but predictability and financial control.
Representation before the Spanish tax authorities
When your accounting and tax filings are properly managed, unexpected issues are rare. However, as there is always a possibility of receiving a notification or inspection request, it is important to have professional representation available.
Because all purchase and sales ledgers, invoices and tax filings are managed through the same integrated software system (Holded), documentation can be accessed quickly and efficiently if required by the authorities. Our clients have peace of mind knowing that their records are accurate, organised and fully compliant.
If a notification or inspection request is received, we handle all communication and documentation on your behalf. You can continue running your business while we manage the technical and administrative aspects of the case.
Ongoing advisory & Strategic planning
One of the main advantages of working with us is the level of ongoing support we provide. Unlike many traditional tax firms, we offer clients the possibility to easily schedule a video call through Calendly after each quarterly VAT and income tax filing.
Many clients use these sessions to better understand their quarterly results — especially their income tax position — and to explore possible optimisations. This may include reviewing deductible expenses, adjusting invoicing structures or discussing potential changes in business structure.
Some clients also use these sessions to evaluate whether transitioning from self-employed status to a limited company (SL) could be more tax-efficient, always ensuring full compliance with Spanish regulations. As your activity evolves, your tax structure should evolve with it — and we guide you through each stage.
Why choose our English-speaking tax advisors in Spain?
Specialists in expats & international clients
We understand the specific needs of expats, digital nomads and international freelancers operating from Spain. Coming from countries with different service standards, many expect faster and more structured communication than what is traditionally offered in Spain.
While some accounting firms respond “when possible”, we commit contractually to replying to client queries within a maximum of 48 hours. Clear expectations and reliable communication are part of the professional standard we provide.
Clear communication in English
One of our core pillars is professional communication in English. We ensure that all members of our team are able to communicate clearly, proactively and confidently in professional English.
For many expats, understanding complex tax concepts in a second language can be stressful. We make sure explanations are clear, practical and easy to follow from day one.
Transparent fees
From the initial consultation call, we explain in detail what is included in our monthly services. While it may sometimes seem more agile to onboard a client quickly, we believe it is more important to clearly define what is — and is not — included.
Once a client decides to move forward, we provide a detailed service agreement outlining all conditions with maximum transparency. This avoids misunderstandings and ensures a long-term professional relationship built on trust.
Proactive tax optimisation
During the onboarding session, we analyse and explain the most suitable and compliant setup for your specific situation. Because we are highly familiar with marketing and technology consultants, we can quickly identify the most efficient structure while ensuring full compliance with Spanish tax regulations.
Our goal is not only to file taxes correctly, but to legally minimise your tax burden through proper planning from the outset.
Cross-border expertise
Many clients believe their case is simple because they only work with two or three clients. However, low billing volume does not necessarily mean low complexity. Any expat operating from Spain requires a certain level of specialised tax knowledge.
One of the first aspects to analyse is tax residency. Contrary to common belief, Spanish tax residency is not determined solely by the 183-day rule. The “centre of economic interests” test may trigger tax residency from the first day of activity in Spain.
We also review double taxation treaties, foreign rental income, cryptocurrency holdings and any other worldwide income that may affect your Spanish tax obligations.
Experience with remote professionals
Remote professionals require specialised tax advice to ensure a compliant setup from day one. They also expect efficient, digital communication.
We train our clients to use the platform through which we exchange documentation, manage bookkeeping and file tax returns. This makes the entire process simple, organised and efficient from the very beginning.
Frequently Asked Questions
Do I need an accountant as a freelancer in Spain?
Yes — and ideally one specialised in freelancers and international clients. The most important step is ensuring your initial setup is correct. This includes determining your tax residency status, analysing your centre of economic interests, and reviewing whether double taxation treaties apply in your case.
An incorrect initial configuration can create tax inefficiencies or compliance issues later. Working with a specialised advisor ensures your structure is compliant from the start.
How much tax do autónomos pay in Spain?
Self-employed individuals in Spain typically pay two main types of contributions: income tax (IRPF) and Social Security contributions.
Quarterly income tax payments are generally around 20% of net profit, although the final annual tax rate is progressive, ranging from approximately 19% to 47% depending on total income. At year-end, quarterly payments are deducted from the final tax calculation, which may result in either a refund or an additional payment.
Regarding Social Security, most new autónomos benefit from a reduced flat rate during the first year (currently around €87 per month, subject to eligibility). From the second year onwards, contributions depend on income levels, starting at approximately €200+ per month depending on declared earnings.
Can I invoice clients abroad?
Yes, you can invoice clients abroad without any issue. Whether VAT applies depends on where your clients are located.
In many cases, when invoicing companies outside Spain, services are VAT-exempt. However, specific legal references must be included on the invoice. If your clients are located within the European Union, registration in the intra-community operators registry (ROI) may be required.
From 2027 onwards, invoices must comply with the Verifactu system, which connects invoicing software directly with the Spanish Tax Agency. All our clients already use compliant software systems.
What happens if I miss a tax deadline?
If you are our client, this situation is highly unlikely, as we closely monitor all deadlines. However, if you are joining us after working with another advisor and a deadline was missed, the best approach is to file the return as soon as possible.
In many cases, filing voluntarily before receiving a formal notification reduces potential penalties, as it demonstrates good faith towards the tax authorities.
Can you represent me before Hacienda?
Yes. We formally represent all our self-employed clients before the Spanish Tax Agency. While it is uncommon to receive notifications when tax obligations are properly managed, audits or information requests can occasionally occur.
If that happens, we handle the communication and manage the process on your behalf, allowing you to focus entirely on running your business.
If you are planning to operate as self-employed in Spain and want clarity, structure and reliable support in English, book a call and we will assess your case.
