Is it serious?
For the next tax declaration, no:if the employer does not do so at the end of the year, he is asked for a letter attesting to the income he has declared for taxes. On the other hand, it can be annoying for the calculation of the retirement.
What do I do?
We contact the personnel department of his box. The pay slips being archived, he will issue us duplicates, or a certificate indicating the salaries received per year. If you have worked in several companies, you send a request to each of them.
What if the box no longer exists?
There, there is no way to recover his ballots. You contact your pension fund (the CARSAT in the provinces and the CNAV in Ile-de-France, when you are an employee of the general scheme). We communicate the name and address of his ex-employer, with, at best, a work certificate. After at least 3-4 weeks, while the archives department is doing its research, you will receive a career statement indicating the amounts of your gross salary and your old-age contributions.
