Generate Italian Tax Code

The Tax Code is calculated by combining: 3 letters from surname (consonants + vowels), 3 letters from first name (with special rule for 4+ consonants), 2 digits for year, 1 letter for month, 2 digits for day (+ 40 for women), 4 characters for the municipal cadastral code, and 1 check letter calculated with a specific algorithm.

The cadastral code (or Belfiore code) is a 4-character alphanumeric code that uniquely identifies each Italian municipality. It starts with a letter followed by 3 digits. For example, H501 is the code for Rome, F205 for Milan. For those born abroad, the country code is used (starts with Z).

If the name contains 4 or more consonants, the 1st, 3rd and 4th consonants are taken. For example, for "ALESSANDRO" the consonants are LSSNDR and L, S, D are taken -> LSD. If there are fewer than 4 consonants, vowels are added as with the surname.

No, this tool generates a "presumed" tax code based on the standard algorithm. The official tax code is assigned by the Revenue Agency and in case of homocody (same personal data) modifications are made to ensure uniqueness.

Surname, first name, date of birth, sex and the four character cadastral code of the town of birth, which is typed by hand. Those are enough to build the sixteen characters of the code.

It is a presumed code, because it follows only the standard algorithm. The official one is issued by the Agenzia delle Entrate, which changes some characters when two people would otherwise share a code.

The cadastral code, also called Belfiore code, is one letter and three digits and it identifies the town of birth: H501 is Rome, F205 is Milan. People born abroad use the country code, which starts with Z.

Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.

No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.

We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads on the page are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.

From the ads on the page, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
