As a foreign student, your student permit allows you to work only on a PART-TIME basis for a maximum of 1040 hours per year in order to be able to maintain pay for your studies.
The part-time can be either “vertical” or “horizontal”; it means that You can work either 20 hours per week for 12 months or up to 40 hours per week for 6 months.
In any case You have to remember that, your work contract cannot exceed the duration of your student permit.

Our translation: Article 14, paragraph 4, Presidential Decree 394/99, requires that the same be carried out for a time not exceeding 20 hours per week, even cumulative for fifty-two weeks, without exceeding the annual limit of 1,040 hours. The reason lies in the fact that the study must always constitute the prevailing activity, which is why the National Inspectorate, in its note of 24 May 2022, specified that in the case of employment contracts that are extended throughout the year, the two limitations must generally be considered simultaneously.
When, on the other hand, the holder of a residence permit for study concentrates the work activity in a shorter time frame than that of the 12 months (which is frequent, for example in the period in which the courses attended are suspended), the student is free to organize the performance of the work activity in such a way that, even exceeding the limit of 20 hours per week, the maximum of 1,040 hours per year is respected in any case.It remains that in the event that the holder of the study permit wishes to carry out work with a commitment exceeding the limit of 1,040 hours per year, he will have to convert this permit into a work permit, within the limits of the entry fees fixed by the so-called decreto flussi.
