Hiring Your First Employee in Italy: The UNILAV Mandatory Notice

In a Nutshell

The UNILAV Mandatory Notice (called Comunicazione Obbligatoria, or CO) is the electronic declaration every employer must submit to the public administration before a new employee starts work. A single submission simultaneously notifies INPS (Italy's social-security agency), INAIL (Italy's workplace-injury insurance institute), the Centro per l'Impiego (public employment centre), the Labour Inspectorate, and the Prefettura (regional state-government office representing the central state). Skip it and you're exposing yourself to undeclared-labour penalties of up to €11,700 per worker.

Who Must File and When

The CO is mandatory for all private businesses, self-employed professionals with staff, private individuals hiring housekeepers or caregivers, cooperatives, and staffing agencies.

You must file one every time you:

• Hire a new employee (UNILAV form)
• Convert a contract (e.g., fixed-term to permanent)
• Extend a fixed-term contract
• The employment relationship ends (resignation, dismissal, contract expiry)
• Carry out a secondment or transfer

You do not need a CO for genuinely self-employed workers with their own Partita IVA (Italian VAT number — required to invoice as a self-employed worker), for non-subordinate collaborations, or for pure volunteer work.

The Midnight Rule — Pay Attention

The law is unambiguous: the CO must be submitted by the day before, even if that day falls on a public holiday, meaning by 11:59 PM the night before work begins.

Example: your employee starts Monday 15 September at 9:00 AM. The CO must be sent by 11:59 PM on Sunday 14 September.

There is one narrow exception for documented force majeure — a sudden emergency replacement due to serious illness, or an exceptional natural event. In that case you may file within 5 calendar days of the start date, but you must notify the Labour Inspectorate by email or PEC (certified email — legally valid in Italy) on the very day the employment begins.

Three Ways to File

Via Sintesi Lazio (the standard route in Rome)

In Rome and the wider Lazio region, the regional system is Sintesi. On your first visit you register as a company and receive login credentials. You then fill in the UNILAV form with your company details (registered address, applicable collective agreement CCNL, industry code ATECO), the employee's details (tax ID, address, nationality), contract type, start date, working hours, and pay. Once submitted you receive a protocol reference number — keep it, it is your proof of filing.

Via Cliclavoro (national portal)

An alternative run by the Ministry of Labour at cliclavoro.gov.it. The process is identical: company registration, UNILAV form, submission, protocol receipt.

Via a labour consultant

If you'd rather not handle it yourself, a licensed consulente del lavoro (labour consultant) can file the CO on your company's behalf. Typical cost is €20–50 per single notice, or it may be included in a monthly retainer (roughly €200–400 for full payroll, CO filings, and contribution payments).

Documents You Need

For the company: chamber-of-commerce registration extract (Camera di Commercio Roma), INAIL employer code (PAT number), INPS registration number (if already active), applicable collective agreement (CCNL), industry code (ATECO).

For the employee: identity document and Codice Fiscale (Italian tax ID — your personal 16-character code), residence permit if the worker is a non-EU citizen, and disability card if relevant for mandatory-quota positions.

Hiring a Non-EU Citizen: Check First

When the CO involves a non-EU worker, the system forwards the data to the Prefettura for residence-permit verification. Before you file, always confirm that:

1. The permit is still valid (not expired)
2. It authorises employment — a tourist or medical-treatment permit generally does not
3. A postal receipt for an ongoing renewal counts as a valid document

Permit types that allow standard employment include: EU long-term resident permit, work permit, family-reunification permit, international-protection or asylum permit, student permit (limited to 20 hours per week), and job-seeker permit.

Hiring a worker without a valid permit exposes you to a fine of up to €15,000 per worker and potential criminal liability.

Mistakes to Avoid

1. Filing the CO on the same day work starts. The law requires the day before. Last-minute technical problems leave you exposed to a late-filing fine of up to €500.
2. Not checking a non-EU worker's permit before filing. If the Prefettura flags an invalid or non-qualifying permit, the employer bears full responsibility.
3. Forgetting to file the termination notice. If you don't send a CO for the end of employment, the contract stays formally active in the system, social-security contributions accrue incorrectly, and the worker may run into problems claiming NASPI (Italy's unemployment benefit).

Special Cases

You need someone urgently, right now? Document the reason thoroughly. The 5-day extension only applies to genuinely exceptional circumstances. Without solid documentation you'll be treated as a late filer and fined.

Using a different form? The UNILAV form covers standard employment. Domestic workers (housekeepers, carers) use a simplified INPS procedure with the UnIDom form. Maritime workers use UnIMARE. Using the wrong form isn't just a technical error — it can be treated as a failure to notify at all.

Is this your very first hire ever? Filing the CO automatically opens your INPS employer registration and, where required, your INAIL position (PAT). Within 30 days of the start date you must also arrange a pre-employment medical check (if the role requires one) and mandatory workplace-safety training (DLgs 81/2008 — minimum 4 to 12 hours depending on the role).
