Key rules

• Spanish clients: On the digital nomad visa, a self-employed applicant may take at most 20% of professional income from Spanish companies.
• Job offers: Never pay anyone for a job offer, visa or appointment; official fees go through official channels.
• Informal work: Working without authorisation can mean a fine, expulsion and an entry ban for you, and much larger fines for your employer.
• One client: If over 75% of your income comes from one client, you may be treated as economically dependent.

The short version

If your plan to pay for life in Spain rests on one client, an offer you have not verified, or work without authorisation, treat it as fragile. Reshape it before you move or before you count on the money. The documents, checklist and warnings below the page text show how.

One remote client

Depending on a single client is risky, even if the client is solid. If that client leaves, your qualifying income can disappear with it, and your renewal can be at risk.

For the digital nomad visa, your remote work must be for companies outside Spain. If you are self-employed, no more than 20% of your professional income may come from Spanish companies. So you cannot fix a thin client base by simply signing up Spanish clients.

There is also a tax angle. If more than 75% of your income comes from one client, Spanish authorities may treat you as economically dependent, which brings its own rules. A single source of income also makes it harder to prove your income when an office asks.

What to do:

• Work out what share of your income your biggest client pays.
• If it is high, add a second client before you move, ideally outside Spain if you want the digital nomad visa.
• Keep invoices and contracts for every client.

If you are thinking of the Beckham regime, which can tax some residents at a flat 24% on Spanish income up to a threshold, it comes with conditions. Check them with a tax adviser before you build your plan on it.

A job offer you have not verified

A real offer comes in writing, and you can check it. Do these checks before you rely on it:

• Look up the employer's tax ID (CIF/NIF) and its entry in the Registro Mercantil to confirm the company exists and is active.
• Ask for a written contract with a salary at or above the collective agreement and the minimum wage.
• Confirm the employer is registered with Social Security and up to date on tax and social security payments, and can afford to pay you.

If you are not an EU citizen, the employer normally applies for your work authorisation through the immigration office (Extranjería). For qualified roles this goes through the UGE-CE. It is usually subject to a test of the national employment situation, unless the job is on the shortage occupation list. Ask the employer directly whether they will do this. EU citizens do not need work authorisation.

Never pay anyone for a job offer, visa or appointment. Official fees go through official channels.

Informal work

Working without authorisation is a serious offence for non-EU nationals. You can be fined, commonly between 501 and 10,000 euros, and expelled with an entry ban. Expulsion often replaces the fine.

Your employer faces much bigger penalties, commonly from 10,001 to 100,000 euros, plus back-payments to Social Security and possible criminal liability. That makes an employer who offers cash work without a permit a bad sign in itself.

It also hurts you later. Informal work builds no Social Security record. Routes such as arraigo rely on proof of time in Spain and, in some cases, work contracts. A sanction file can also complicate a residence application.

How to reshape the plan

• One client: add a second, and keep to the 20% limit on Spanish income if you want the digital nomad visa.
• Unverified offer: complete the checks above, and get the contract in writing.
• Informal work: do not start. Get authorisation first, or find an employer who will apply for it.

If you are unsure which route fits you, ask the immigration office or a tax adviser before you commit.

Documents you need

• A written employment contract from the employer, stating a salary at or above the collective agreement and the minimum wage.

• The employer's tax ID (CIF/NIF), so you can confirm the company exists and is active.

• Proof of the employer's registration in the Registro Mercantil, the Spanish company register.

• Proof that the employer is registered with Social Security and up to date on tax and social security payments.

• Proof of time in Spain, and in some cases work contracts, if you may later need a regularisation route such as arraigo.

Checklist

• Ask for the contract in writing before you rely on the offer.

• Work out what share of your income comes from your biggest client, and look for a second client if it is over 75%.

• Count the share of your professional income from Spanish companies if you plan to apply for the digital nomad visa, and keep it at 20% or less.

What to watch out for

• Working without authorisation: Working without authorisation is a serious infringement. You face a fine, commonly between 501 and 10,000 euros, and you can be expelled with an entry ban, although expulsion often replaces the fine. Do not start work until your authorisation is in place, and ask a genuine employer to confirm in writing how it will be obtained.

• Heavy penalties for your employer: An employer who uses unauthorised workers faces much larger fines, commonly from 10,001 to 100,000 euros, plus social security back-payments and possible criminal liability. An offer that skips the paperwork is a warning sign. Walk away from any employer who offers cash-in-hand work or says no contract is needed.

• No record to support later applications: Undocumented work builds no social security record, which hurts routes like arraigo that rely on proof of time in Spain. It can also leave a sanction file that complicates residence applications. Keep only work that is contracted and registered, and keep copies of every contract and proof of your time in Spain.

Frequently asked questions

How much Spanish income can a self-employed digital nomad visa holder have?

A self-employed digital nomad visa applicant can have at most 20% of professional income from Spanish companies. The rest must come from clients outside Spain, so one foreign client makes the plan fragile: if you lose that client, your qualifying income ends and renewal is at risk.

What does it mean if over 75% of my income comes from one client?

If more than 75% of your income comes from one client, Spanish authorities may treat you as economically dependent on that client. This is called TRADE status and has its own rules. Ask a tax adviser how it would apply to you before you rely on a single client.

Can I be expelled for working informally without a work permit?

Yes, you can be expelled with an entry ban if you work without authorisation, although expulsion often replaces the fine. The fine is commonly between 501 and 10,000 euros. Your employer faces far larger fines, so a genuine employer will not ask you to work without a permit.

Does informal work affect a later residence application?

Yes, informal work can hurt later applications such as arraigo, a residence route for people who have built ties in Spain.
