Single filer with the standard employee credit (detrazione da lavoro dipendente) and a ~2% national-average regional/municipal add-on. The tredicesima is near-universal; the quattordicesima depends on your CCNL — commerce and banking usually have it, metalworking doesn't.

The tredicesima's December catch

Italy's 13th payment arrives with the December payroll — but unlike Austria's flat-taxed extras, the tredicesima is taxed at your full marginal rate, and the standard detrazioni aren't applied to it. The practical result surprises people every year: a €2,000 gross tredicesima lands as roughly €1,400–€1,500 net, noticeably less than a regular month. It's still a genuine extra month of pay; it just shrinks more on the way in.

Reading Italian job offers, the only unambiguous figure is the RAL (Retribuzione Annua Lorda — gross annual). "€2,000 al mese" with a 14-mensilità CCNL is a better deal than "€2,150 al mese" on 13 (€28,000 vs €27,950 RAL) — the kind of comparison the monthly framing is built to blur.

Frequently asked questions

With 13 payments (€26,000 RAL): €1,668 net a month averaged. With 14 payments (€28,000 RAL): €1,768. Effective deduction rates are 23.0% and 24.2% respectively.

It's taxed at your marginal IRPEF rate without the monthly detrazioni, so it nets less than a regular month — roughly €1,400–€1,500 from a €2,000 gross instalment at this level.

Above the Italian median — a solid skilled wage. €1,768 averaged monthly net lives well in Naples, Palermo or Bologna's periphery, and adequately in Milan, where one-beds at €1,000–€1,400 consume most of it.

Retribuzione Annua Lorda — the gross annual salary, the only figure that neutralises the 13-vs-14 ambiguity. Italian recruiters negotiate in RAL; you should too.
