When must a foreign haulier declare a posting to Spain?

When it carries out cabotage within Spain (the driver is always considered posted) or cross-trade loading or unloading in Spain (transport whose other end is not the haulier's country of establishment). Transit through Spain and bilateral transport between the country of establishment and Spain are exempt. The declaration is filed on the European RTPD portal before starting.

What is the fine for not declaring a posted driver in Spain?

Not filing the posting communication (or filing it falsely) is a very serious infringement under the LISOS: €7,501 to €225,018. Filing late or not having the documentation available is a serious infringement (€751-7,500), and formal defects are a minor infringement (€70-750).

What liability does a Spanish shipper have when it contracts a foreign haulier?

Shippers, operators and intermediaries who regularly contract transport must check that the actual haulier has filed the posting communication (art. 22.4 of Law 45/1999) and are jointly liable with it for infringements (art. 42 LISOS). The practical way to protect yourself is to request the copy of the RTPD declaration before loading.

What happens if my Spanish company receives a documentation request via IMI?

When another country requests documentation for a Spanish driver after a posting, the request arrives through the IMI system with the ITSS as the intermediary, and the company has 8 weeks to submit the contract, payslips, time records and proof of payment. Not responding is sanctionable and foreign fines can be enforced in Spain.

Is a bilateral transport exempt from declaring in Spain?

Yes: bilateral transport between the haulier's country of establishment and Spain is exempt in both directions, the same as transit. Spanish law states this expressly (arts. 19-20 of Law 45/1999). The social security A1 certificate always applies, including in exempt operations.

Posting drivers to Spain: requirements, wages and penalties 2026

Q: What wage must be paid to a driver posted in Spain in 2026?

The absolute floor is the SMI 2026: €1,221/month over 14 payments (€17,094/year, RD 126/2026). But the real reference owed is the pay under the applicable freight transport collective agreement, which in Spain is set provincially: the figure varies by the province where the work is performed. Per diems that compensate expenses do not count.

Published and reviewed: 3 July 2026 · Verified against the BOE (Law 45/1999, RDL 3/2022, LISOS, RD 126/2026), the Ministry of Labour (MITES) and Directive (EU) 2020/1057.

This page looks at posting from the Spanish side: what a foreign haulier operating in Spain must do, what a Spanish shipper or operator who contracts it risks, and what obligations a Spanish company has when it is its own drivers who are sent abroad. If you're looking for other countries' requirements, they're at the end.

In 30 seconds

When to declare in Spain: cabotage within Spain and cross-trade loading or unloading here require a prior declaration on the RTPD portal. Transit and bilateral (haulier's country ↔ Spain): exempt.
Wages: SMI 2026 floor = €1,221/month × 14 payments; the real reference is the provincial collective agreement for transport in the province where the work is performed.
Fines (LISOS): not declaring is very serious: €7,501 – 225,018; documentation issues, serious: €751 – 7,500.
The Spanish shipper is jointly liable if the foreign haulier it contracted failed to declare (arts. 22.4 Law 45/1999 and 42 LISOS).

When must a foreign haulier declare in Spain?

The rule is the same across the EU, set out in Chapter V of Law 45/1999 (BOE): you must declare cabotage within Spain (the driver "shall in all cases be considered a posted worker", art. 21) and cross-trade loading or unloading in Spain (e.g. a Polish haulier that loads in France and unloads in Madrid). Transit through Spain without loading or unloading and bilateral transport between the country of establishment and Spain, in both directions, are exempt, including the limited additional bilateral activities (1+1 or 0+2, with border crossings recorded on the tachograph).

Practical rule: if a foreign-registered truck runs a Spain→Spain leg, or a third-country→Spain leg that doesn't touch its country of establishment, its driver must be declared on the RTPD before starting. The general rules with a full decision tree are in our posting declaration (IMI) guide — or check the case in 1 minute with the "Do I need to declare?" checker.

Golden rule: being exempt from declaring does not mean being exempt from the A1 certificate, which always applies — including in bilateral and transit operations.

Where do you declare?

Exclusively on the European RTPD portal (postingdeclaration.eu), with the multilingual form connected to the IMI system, before the posting begins and per driver [art. 22 Law 45/1999]. Each declaration is valid for up to 6 months (portal limit) and is renewable; the IMI repository keeps the information for 24 months for verification purposes. The Spanish rule governing it is Royal Decree-Law 3/2022 (BOE), which inserted the special driver rules (arts. 18-24) into Law 45/1999.

What wage applies in Spain in 2026?

The driver posted in Spain (cabotage or cross-trade) is entitled to Spanish pay from day one. Two references:

2026 reference	Amount
SMI (absolute floor, RD 126/2026)	€1,221/month × 14 payments = €17,094/year gross
Real pay owed	That of the provincial collective agreement for freight transport in the province where the operation takes place

Source: RD 126/2026 (BOE) and MITES.

The Spanish quirk that trips up foreign hauliers: transport wage tables are provincial (with the state-level II General Agreement as a framework), so the figure owed varies by province — there's no single national table. And as everywhere in the EU, per diems that compensate real expenses do not count toward that pay [art. 3.7 of Directive 96/71].

What must the driver carry on board in Spain?

The same as elsewhere in the EU [art. 23.1 Law 45/1999]: the copy of the RTPD declaration, the consignment note (Spanish law expressly names the e-CMR) and the tachograph records. The contract, payslips, working-time records and proof of payment are requested afterwards, through the IMI system, with an 8-week deadline [art. 23.2].

Penalties in Spain (2026)

Non-compliance	Classification	Penalty (art. 40 LISOS)
Not filing the posting communication, or filing it with falsehood or concealment; fraudulent posting ("letterbox companies")	Very serious	€7,501 – 225,018
Late filing; not having the documentation available during the posting; not responding to the ITSS request (8 weeks)	Serious	€751 – 7,500
Formal defects in the communication	Minor	€70 – 750

Categories under art. 10 LISOS adapted to drivers by RDL 3/2022; amounts in force under art. 40 LISOS (consolidated text, BOE). The declaration is per driver, so in inspection practice each undeclared driver can be treated as an independent infringement.

There is also a parallel front via the transport law (LOTT): penalties for irregular cabotage and for breaching the ban on the driver loading or unloading. Calculate your exposure with the penalty calculator.

The part almost no one tells you: the Spanish shipper is liable

If you contract transport regularly, this affects you directly. Art. 22.4 of Law 45/1999 requires shippers, hauliers, transport operators and intermediaries to check that the actual haulier they contract has filed the posting communication. And art. 42 LISOS makes them jointly liable for infringements: the fine for your foreign subcontractor's undeclared driver — up to €225,018 in the very-serious bracket — can end up on your desk.

The practical way to protect yourself is simple: ask for the copy of the RTPD declaration before loading (the driver must carry it, on paper or on the phone). It's the same pattern already applied by Germany, Italy and Belgium with their shippers — Spain has had it since 2022 and inspection plans include it.

And if you're a Spanish haulier: your role as the country of establishment

When your drivers are posted abroad and another country requests documentation after the trip, the request arrives via IMI with the ITSS as the intermediary, and you have 8 weeks to submit the contract, payslips, time records and proof of payment. Not responding is sanctionable, and foreign fines can be enforced in Spain through cross-border recognition of penalties. In practice: every posting must be reconstructable as a case file (declaration + CMR + tachograph + payslip) long after the trip is over — which is exactly what MovingCert stores for you.

Who enforces it and how

The ITSS is the Spanish authority under the IMI system for posted drivers (documentary requests, LISOS case files). On the road, the Road Transport Inspectorate together with the Guardia Civil act, and the 2026 Road Transport Inspection Plan expressly includes checking IMI declarations. Spain also takes part in joint roadside inspections with the European Labour Authority (ELA).

MovingCert files and renews your declarations, keeps the complete case file for every posting, and warns you before anything expires — all 5 transport formalities on a single platform: IMI, DeCA, e-CMR, A1 and CAP.
