If you run a company in Italy or manage a business as a foreign entrepreneur, keeping up with Italian fiscal deadlines is one of the most demanding parts of operating in this country. The Italian tax calendar is dense, changes regularly, and is almost entirely documented in Italian — which creates a real barrier for international business owners and company administrators.
That is why Studio Lombardo Larosi has created a free, downloadable guide to Italian fiscal deadlines 2026, fully in English and updated to 20 March 2026.
What is inside the guide?




The guide covers all major tax obligations month by month throughout 2026, including VAT payments and withholding taxes, INPS social contribution deadlines, IMU advance and balance payments, income tax and IRAP deadlines (REDDITI/IRAP), electronic invoicing stamp duty, INTRA model filings, the September deadline to join the Biennial Preventive Agreement (CPB) for 2026–2027, Enasarco commission contributions, and IOSS/OSS e-commerce declarations.
Each entry includes the exact deadline date and any relevant notes — so you know not only what to do, but when and why.
Who is it for?
This guide is designed specifically for foreign entrepreneurs, company directors, and international investors who operate in Italy and need a reliable English-language reference for their tax planning. Whether you already work with an Italian accountant or are building your own compliance workflow, this calendar gives you a clear overview of the entire fiscal year at a glance.
Why does it matter?
Missing a deadline in Italy is not just an administrative inconvenience. Late VAT payments, unpaid INPS contributions, or a late income tax return can trigger automatic penalties and interest that accumulate quickly. Having the full calendar to hand — in a language you actually work in — is the first step toward staying compliant and avoiding unnecessary costs.
