When you are a retired SNCF employee and want to book a trip using your travel benefits, the first challenge is not understanding the principle of the Carmillon pass. It’s successfully connecting to the portal to activate your rights.
The basic mechanism has remained the same for years: former employees retain free or nearly free access to the national rail network, extended under certain conditions to eligible dependents. However, with the recent taxation of this benefit and recurring digital blockages, the on-the-ground reality is less fluid than the stated principle.
Taxation of the retired Carmillon pass: what changes for the tax household
Since travel benefits are treated as a taxable benefit in kind, including for retirees and their dependents, the situation has changed. It is no longer a simple internal privilege without tax consequences. The burden is linked to the retired holder of the pass, even when it is the spouse or a child who is traveling.
In practical terms, a household where several dependents regularly use their benefits may see its taxable income increase significantly. We are not talking about a symbolic amount for heavy users who accumulate TGV and long-distance trips throughout the year.

This point is rarely detailed in guides that generally remind the rules of the retired SNCF Carmillon pass. However, the taxation deserves verification before requesting benefits for the whole family, to ensure that the actual savings on tickets adequately compensate for the impact on the household tax.

Enhanced authentication on the SNCF retirees’ services portal
Since the security of the portal has been strengthened, access to travel benefits requires three-step authentication: employee number, password, and then a temporary code sent via SMS or email. For retirees who had not updated their phone number in their personal space, this double authentication has created a barrier.
Feedback on railway forums is telling. Former employees find themselves in an administrative loop: the Travel Benefits agency refers to Payroll and Family, which refers to the CPRP, which states it does not manage this aspect. The account is blocked, the Carmillon pass suspended, and no one takes charge.
What to check before the renewal period
- Update your mobile phone number in the MFCD (My Dematerialized Travel Benefits) space several weeks before the annual renewal date
- Test the connection to the services-aux-retraites.sncf.com portal well in advance, without waiting until the last moment to discover a blockage
- Keep a written record (screenshots, emails) of any unanswered requests, useful in case of a formal complaint
Responses vary on this point, but several testimonies indicate that a physical visit to an agency (when one still exists nearby) remains sometimes the only way to unblock a file stuck between three interlocutors.
SNCF dependents: actual conditions for accessing free tickets
The retired Carmillon pass does not only concern the former employee. The spouse and dependent children can benefit from travel privileges, but the conditions deserve attention. The extension to dependents depends on the seniority of the employee and the type of contract (status or contractual).
For children, the right is linked to the notion of tax dependency. An adult child who is no longer attached to the retiree’s tax household loses access to the benefits. For the spouse, marriage or PACS grants the right, but an undeclared cohabitation is not sufficient.
Contribution to reservation fees
Free does not mean total absence of fees. On TGVs, a contribution to reservation fees is still required. During peak periods, access restrictions apply: certain dates are simply closed to travel benefits. Retirees traveling during high season (school holidays, long weekends) must check availability before planning a trip, or risk finding themselves without a solution on the day of departure.

Annual leave ticket SNCF and travel benefits: two distinct systems
The annual leave ticket is often confused with standard travel benefits. The annual leave ticket is a specific system, limited in number and period, allowing one round trip per year at a very reduced rate. It does not replace permanent travel benefits and cannot be combined with them on the same journey.
For a retired SNCF employee, the annual leave ticket may be of interest if traveling to a destination outside the network covered by their benefits, or if they want to travel with a relative who is not an eligible dependent. The two systems fall under different internal rules and are managed in separate areas of the portal.
Travel traceability and enhanced control by SNCF
In recent years, SNCF has strengthened the monitoring of the use of travel benefits. Each trip made with the Carmillon pass is now digitally tracked. The stated goal is to limit abuses (lending the pass to a non-eligible third party, use during closed periods).
For retirees, this traceability means that any anomaly, even unintentional, can trigger a temporary suspension of rights. A trip booked in the name of a dependent who no longer appears on the updated list in the MFCD portal is enough to block the account. Restoring compliance involves an administrative procedure that can take several weeks.
- Check each year that the list of dependents is up to date in the MFCD space
- Never lend your pass or book a ticket for a non-declared person
- Report any changes in family situation (divorce, death, child leaving the tax household) as soon as possible
The retired SNCF Carmillon pass remains a substantial benefit for former railway workers, provided they manage the administrative aspects surrounding it. Between taxation, access blockages to the digital portal, and enhanced traceability, the real benefit depends as much on the vigilance of the retiree regarding their file as on the right itself.
