Spain is one of the few countries where freelancers and remote workers can live legally, pay relatively straightforward taxes, and continue working with clients abroad. But between “I moved to Spain” and “I’m working legally” lies a layer of bureaucracy: registration with two government authorities, activity codes, a digital certificate, quarterly tax returns, and a tax calendar that nobody is going to email you about.
Below, we explain why a digital nomad may need autónomo status, what exactly you need to do, and when it makes sense to hand the process over to a platform like Reglapp, which combines a personal licensed gestor with an AI assistant for Spanish taxes.
Part 1. Seven Reasons Why a Digital Nomad Needs Autónomo Status
1. Your residence permit may require it
Spain’s Digital Nomad residence permit can be obtained under two main arrangements: as an employee of a foreign company or as a self-employed professional.
If you work with several clients, have service contracts, or run your own projects, you fall into the second category, which means autónomo status is not optional — it is part of the conditions for legally carrying out your activity in Spain. The same applies to residence permits based on cuenta propia.
One important detail: after receiving a positive decision from the immigration authority (UGE), you have a limited window to complete your registration. Delaying it can mean formally breaching the conditions under which your residence permit was granted and may create problems when you renew it.
2. Tax residency happens automatically — whether you intend it or not
If you spend more than 183 days in Spain during a calendar year, you become a Spanish tax resident.
Not “you may become one” — you are one.
Spanish tax residents generally have to declare their worldwide income: fees from a US client, dividends, the sale of property in another country, investment income, and so on.
There is another important consequence: depending on the circumstances, you may be treated as a tax resident for the tax year even if you only registered as autónomo in June.
Income received before your autónomo registration does not simply disappear. It still needs to be handled correctly.
That is why the question “What should I do with the money I earned before moving or registering?” is much better discussed with a specialist before registration rather than in April of the following year.
3. Seguridad Social gives you access to the social security system — it is not just another tax
The monthly contribution to Seguridad Social under RETA is not simply a “self-employment tax.”
It provides access to public healthcare, sick leave benefits, maternity and parental benefits, benefits in case you cease your activity, and contributes towards your future pension.
There may also be family-related benefits and deductions, including deductions for children, maternity deductions where applicable, and access to healthcare coverage for eligible family members.
4. Without officially declared income, you are practically “invisible” to banks and landlords
A Spanish bank will not assess your income based on screenshots from Revolut.
It will look at your filed tax returns, income history, and employment or contribution records such as your Vida Laboral.
A mortgage, car loan, or even a good rental contract without having to provide six months’ worth of deposit can depend on having a documented financial and tax history in Spain.
The practical conclusion is simple: if you think you may want a mortgage in one or two years, start building a transparent financial history and do not postpone your autónomo registration indefinitely.
5. Legal tax optimisation can save you more than grey-area schemes
The Spanish system is structured in such a way that an autónomo who keeps proper records and claims legitimate deductions can pay considerably less than someone who simply pays tax on revenue without deducting anything.
Some of the options available include:
- Tarifa plana — a reduced Seguridad Social contribution of around €87 per month during the first year instead of approximately €300, with the possibility of extending it for another 12 months if your income remains below the applicable threshold.
- 20% reduction for new entrepreneurs — a reduction in the IRPF taxable base during the first profitable tax year and the following year. Not every accountant remembers to apply it, yet it can be worth thousands of euros.
- Professional expenses — equipment, software and subscriptions, training, insurance, business travel, bank fees, gestor services, and eligible portions of utilities and rent.
- Regional deductions — every autonomous community has its own set of deductions, ranging from certain healthcare or sports expenses to first-home purchases and investments in new companies.
6. Working with EU business clients requires additional registration
If you work with businesses in other EU countries, you may need to register in VIES and obtain a valid intra-EU VAT number.
Invoices can then be issued without Spanish IVA under the reverse-charge mechanism where applicable, while the corresponding transactions are reported through Modelo 349.
Without a valid VAT number, your German or Dutch business client may refuse to work with you or the transaction may be treated differently for VAT purposes.
7. Renewing your residence permit means proving your history
When it is time to renew your residence permit, the authorities will not simply ask you what you have been doing.
They can look at documentation: contributions paid, tax returns filed, and documented income.
Properly managed autónomo activity can make renewal much more straightforward. Gaps in tax reporting or Social Security payments can make the process significantly more complicated.
Part 2. What to Calculate Before You Register
Business structure
Autónomo is not the only possible structure.
There is also the combination of an autónomo with an autónomo colaborador when a spouse or adult child genuinely participates in the business, as well as an SL — the Spanish equivalent of a limited liability company.
The point at which an SL becomes more attractive than operating as an autónomo depends on your income, region, expenses, and business structure.
It should be calculated using your actual numbers rather than advice from online chats.
Timing your registration
This is one of those situations where the calendar can literally cost you money.
The 20% reduction for new entrepreneurs is linked not simply to your alta date but to your first tax year with positive net income and the following tax year.
If you register in November, work profitably for two months, and qualify for the reduction, you may effectively use an entire tax year of the benefit for only those two months.
If you begin activity in January, you can potentially benefit from two full calendar years.
If your residence permit requirements allow you to choose the timing, it may therefore make sense to plan your start carefully.
Budget
Estimate three main expenses in advance:
- Seguridad Social contributions;
- IRPF, with progressive rates of roughly 19% to 47%;
- accounting/gestoría costs.
Think about IVA separately. The 21% IVA you collect from Spanish clients is not really your money — it is tax collected for the Treasury.
How Reglapp helps here. Before subscribing, you can speak to the AI assistant for free. It works in Russian, English, Spanish, and Turkish and relies on an official knowledge base rather than random internet articles: consultas vinculantes, the AEAT inspector’s manual, and current Spanish legislation. For non-standard situations, a one-off consultation with a licensed gestor costs €150. One such consultation per month is included in the Pro plan.
Part 3. Step-by-Step Registration
Step 1. A residence permit with the right to work and an NIE
This is your starting point.
You need a legal status that allows you to carry out economic activity in Spain, such as Digital Nomad status, cuenta propia, arraigo, temporary protection, or another qualifying status.
You will also need an NIE and eventually your physical TIE card, although waiting for the TIE should not necessarily block the rest of the process.
Reglapp: the team includes specialists in extranjería, while the AI assistant can answer questions about visas and legalisation. The service is designed as a single journey: relocation → NIE → autónomo → tax reporting, without having to coordinate three separate providers.
Step 2. Decide who will handle your accounting
There are three realistic options:
- a private gestor;
- an automated platform;
- a hybrid model.
A hybrid model automates routine processes and provides a digital interface while a real licensed professional remains responsible for reviewing and filing your tax returns.
Reglapp: this is the model Reglapp uses. You have a dedicated gestor who knows your history and can see your documents rather than dealing exclusively with a generic support line. Plans are €80/month for Basic and €130/month for Pro, excluding IVA. With annual payment, two months are free. Autónomo registration costs €0 with either subscription.
Step 3. Collect your documents
The basic set usually includes:
- NIE/TIE;
- registered address;
- Spanish bank account details;
- a clear description of your professional activity.
The last point is more important than it sounds because it affects the selection of your IAE activity code.
Reglapp: you complete a short application, after which a specialist contacts you in your language. Together, you collect the documents and define your activity. You can then track the process in your personal account.
Step 4. Spanish bank account
A Spanish bank account is important for automatically paying Seguridad Social contributions and managing tax payments.
If you are planning to apply for a mortgage in the future, it is also useful to build a clear history of income through your Spanish account.
Practical advice: consider opening a regular personal account linked to your NIE rather than only to your passport. In many cases, visiting a branch can also be easier than trying to complete everything online.
Reglapp: there is a solution for people who do not yet have a Spanish bank account. With the Express Registration service, the first three months of Seguridad Social contributions can be paid from Reglapp’s corporate account. Once you open your own account, the payment details with TGSS can be changed at no additional cost.
Step 5. Choose your IAE epígrafe
Your activity code affects which taxes apply to you, whether you need to include retención on invoices, and which tax returns you need to file.
An incorrect IAE code may not cause an immediate problem. Instead, the issue may appear one or two quarters later in the form of incorrect filings or overpayments.
Reglapp: selecting the correct epígrafe for your actual professional activity is included in the registration process.
Step 6. Register with Hacienda — declaración censal
This is your tax registration.
You declare your activity, address, tax regime, and, where necessary, register for VIES if you work with EU businesses.
Reglapp: Reglapp handles the tax registration and determines which tax returns apply to your specific activity.
Step 7. Register with RETA and apply for tarifa plana
This is your registration with Spain’s Social Security system for self-employed workers.
Two things are particularly important.
The first is timing: tax registration and registration with Seguridad Social must be properly coordinated.
The second is your IBAN.
Seguridad Social contributions are collected automatically. If there is not enough money in the account when payment is due, you may lose the reduced rate for that month and potentially face additional charges.
Check the bank details in your Seguridad Social account immediately after registration, particularly during the first month.
If you register after the first day of the month, your initial payment may also be proportionally lower. Depending on the registration date, the first debit may occur later and include more than one period.
Reglapp: RETA deadlines are handled as part of the process, and eligible clients can receive the reduced first-year contribution of around €87/month instead of approximately €300.
Step 8. Obtain a digital certificate — certificado digital
Think of it as your electronic passport.
It gives you access to Hacienda and Seguridad Social portals, allows you to sign documents, and lets you access official notifications.
Without it, many interactions with Spanish authorities become considerably more complicated.
Reglapp: the digital certificate can be arranged together with the registration through an accredited partner — remotely and, under the Express scenario, even without a physical TIE card. It is included in both plans.
Step 9. Set up electronic notifications through DEHú
Spanish authorities communicate electronically through systems such as DEHú.
Official notifications can have legal consequences even if you fail to read them, and response deadlines may start running accordingly.
Setting up alerts takes only a few minutes. Ignoring official correspondence can be considerably more expensive.
Reglapp: correspondence from the tax authorities can be reviewed and handled as part of the service.
Step 10. Check your EU VAT status and download your documents
After registration:
- check whether your intra-EU VAT number is actually active in VIES;
- download proof of registration;
- obtain your Vida Laboral;
- provide the necessary documentation to your bank so your account correctly reflects your status.
VIES registration is worth checking separately because sometimes the VAT number is not activated as expected.
Step 11. Set up invoicing correctly
The basic rules are straightforward, but they are frequently misunderstood:
- accounting is based on the invoice date, not simply the date the money reaches your account;
- you should not backdate invoices into a previous reporting quarter;
- issuing invoices regularly, for example at the end of the relevant month, makes accounting easier;
- invoices can be issued in different currencies, but Spanish accounting and tax reporting are handled in euros using the applicable exchange rate;
- the invoice language can generally be chosen according to your business needs.
And then there is VeriFactu.
From 2027, invoicing software requirements become stricter, including requirements related to invoice records, integrity and QR codes. Preparing in advance is much easier than trying to change your invoicing system at the end of 2026.
Reglapp: invoices can be created directly through the platform, with VeriFactu requirements such as numbering, payment tracking, and QR functionality built into the process.
Step 12. Start recording expenses correctly
One of the most common and frustrating mistakes among new autónomos is sending receipts to their accountant instead of proper invoices.
A full invoice should contain information such as:
- Factura or Invoice;
- invoice number;
- your name;
- NIE;
- registered address;
- description of the service or product;
- amount;
- date;
- full supplier details.
Without the required documentation, recovering IVA or deducting the expense may not be possible.
Common deductible business expenses can include:
- accounting/gestoría subscriptions and Seguridad Social contributions;
- equipment and furniture;
- software, IDEs and AI subscriptions;
- professional courses;
- business insurance;
- eligible portions of rent and utilities when the legal requirements are met;
- business travel where a legitimate business purpose can be demonstrated;
- banking fees, including fees on international transfers.
If a supplier does not automatically issue a proper invoice, contacting support and requesting an invoice containing your name, address, and NIE will often solve the problem.
Reglapp: expense invoices can be uploaded to your account, and the platform shows an estimate of potential IVA and IRPF deductions for the period. There is also a free “upload one invoice and see what you may be able to deduct” flow, with no subscription required.
Step 13. Quarterly tax returns
Quarterly returns are generally filed during the first 20 days of April, July, October, and January.
A typical set may include:
Tax payments can be collected by direct debit when the declaration is submitted within the applicable deadline.
If there is not enough money in your account when the payment is collected, penalties or surcharges may apply.
Reglapp: the platform determines which modelos apply to you and shows only the relevant ones in your account. Reglapp handles deadlines and preparation, while the final filing with Hacienda is performed by a gestor rather than an algorithm. Modelos 111 and 115 are available under the Pro plan.
Step 14. Annual Renta tax return
The annual income tax return is generally filed between April and June for the previous year.
Autónomos are required to file an annual Renta even in cases where their income was very low or zero.
Depending on your situation, you may also need:
- Modelo 720 — declaration of certain foreign assets where the applicable thresholds are exceeded;
- Modelo 721 — declaration of qualifying crypto assets held abroad where the applicable threshold is exceeded;
- Modelo 714 — Wealth Tax return where the applicable requirements and regional thresholds are met.
Two pieces of advice can save you money.
First, complete any pre-filing questionnaire thoroughly and honestly because this is often where potential deductions are identified.
Second, always review the draft return yourself.
No specialist knows every detail of your personal circumstances as well as you do.
Reglapp: annual reporting is included in the subscription. The Pro plan also includes a monthly 45-minute video consultation with a gestor, which can be useful for reviewing your situation before filing and checking regional deductions and benefits available to new entrepreneurs.
Step 15. Year two: review your settings
After the initial reduced contribution period ends, Seguridad Social contributions are linked to the applicable contribution system and your income.
Your base de cotización and corresponding contribution may need to be adjusted as your income changes.
The contribution base also affects future benefits and pension entitlements.
If your actual income increases significantly and your contributions have been too low, you may later receive a calculation requiring an additional payment. If you have overpaid, the system may refund the difference following reconciliation.
Reglapp: your gestor can identify changes
in your income or activity and advise when your settings should be adjusted. For many new autónomos, this becomes relevant after the first year.
Part 4. Your Annual Calendar at a Glance
Part 5. The Most Expensive Mistakes
- Registering in November or December without considering the tax implications. You may effectively use a full tax year of the 20% new-business reduction for only a short period of activity.
- Not having enough money in your account when Seguridad Social is collected. This may affect your reduced contribution and lead to additional charges.
- Keeping receipts instead of proper invoices. The expense or IVA deduction may not be accepted.
- Choosing the wrong IAE epígrafe. This can result in incorrect tax filings and unnecessary payments.
- Ignoring DEHú. Official notifications may have legal effect even if you do not open them.
- Failing to report income received before autónomo registration. If you are considered a Spanish tax resident for the relevant year, that income may still need to be declared.
- Assuming you only need to file Renta if you earned money. Autónomos are generally required to file the annual return even in zero-income years.
- Failing to claim the new-entrepreneur tax reduction. In some cases this can be corrected later, but it is much better to get it right from the beginning.
