Hiring Your First Employee in Spain: A Guide for Foreign Business Owners

Hiring your first employee in Spain is one of those moments that catches many foreign business owners off guard. It’s not just a matter of signing a piece of paper and starting to pay a salary: you need to register as an employer with Social Security, choose the right type of contract, work out a real cost that runs well above the agreed salary, and file periodic withholding returns with the tax authorities. If you’re used to a system where a single payroll provider handles everything, it will come as a surprise that in Spain this work is split between two distinct professionals: the labor advisor and the tax advisor. Understanding that difference from your very first hire will save you both money and headaches.

The real cost of an employee is not the salary you pay them

When an employee in Spain earns, say, €20,000 gross a year, the company doesn’t just pay out that €20,000. On top of the gross salary, the employer must pay monthly Social Security contributions calculated as a percentage of that salary — covering common contingencies, unemployment, vocational training and the Wage Guarantee Fund (FOGASA) — which together typically add an extra 30% to 33%, depending on the type of contract and the business activity. Depending on the sector’s collective bargaining agreement, there may also be additional allowances or prorated extra payments. In practice, a reasonable rule of thumb for budgeting is to add 30% to 35% to the annual gross salary to arrive at the real cost to the company. Many foreign investors budget only for the salary the employee will actually see, then discover the effective monthly cost is considerably higher; getting this calculation right before hiring is the first step to avoiding cash-flow surprises.

Social Security registration and the employment contract

Before the employee sets foot in the office, the company must be registered as an employer with the Tesorería General de la Seguridad Social (TGSS), the public body that manages social security contributions in Spain. That registration generates a Contribution Account Code (CCC), a number that will identify the company in all Social Security procedures from then on. The specific employee must then be registered — mandatorily before they start working — through the RED system (the official online channel for managing affiliations and contributions). In parallel, the employment contract is formalized and must be registered with the Public State Employment Service (SEPE) within days of the start date. Several contract types exist — permanent, temporary, part-time, internship — and since the latest labor reform, permanent contracts are the general model favored by law, with temporary contracts limited to very specific circumstances. If the foreign employer doesn’t yet have a NIE (Foreigner Identification Number, the ID required by any non-Spanish national to operate here) or is operating through a newly incorporated company, it’s worth sorting out those identification steps before starting the registration process, since the RED system and the CCC depend on having the correct tax ID already in place.

Withholdings, payroll, and why labor advisors and tax advisors aren’t the same thing

Each month, on top of paying the salary and Social Security contributions, the company must withhold an amount from the employee’s pay on account of Personal Income Tax (IRPF), Spain’s tax on individual income. That percentage is calculated based on projected salary, the employee’s family situation and other factors, and the amounts withheld are reported to the Spanish Tax Agency (AEAT) via Form 111, a return that is normally filed quarterly. This is where many foreign business owners assume that their tax advisor — the one handling VAT and Corporate Tax — also manages payroll, and that’s usually not the case: payroll calculations, Social Security registrations and terminations, and contracts are handled by the labor advisor (or “gestoría laboral”), while the tax advisor ensures those withholdings are correctly reported on Form 111 and reconcile with the accounts. Working with both pieces properly coordinated — rather than with providers who don’t talk to each other — avoids the most common pitfall: a correctly calculated payroll that later doesn’t match what was reported to the tax authorities.

At Zythos Business we support freelancers and small and medium-sized businesses, including those with foreign owners, through decisions like these from day one: from estimating the real cost of hiring before you post the job ad, to coordinating with the labor side so that Form 111 withholdings and the accounts reconcile without surprises every quarter.
