A letter from the CAF? Here's what it's probably about.

The Caisse d'Allocations Familiales pays housing aid, family benefits, and the RSA to millions of people in France — and its letters are the single biggest source of "why did my payment stop" panic among expats.

Quick answer: If your CAF payments stopped, the most common reason is a missed quarterly income declaration (déclaration trimestrielle) or a missing document. Log into Mon Compte on caf.fr, submit what is missing, and payment usually resumes. An “indu” or “trop-perçu” letter means the CAF believes it overpaid you and wants the difference back.

Why the CAF is writing to you

The CAF recalculates your entitlement constantly based on your declared income and situation, which means it writes often — sometimes just to confirm a routine update, sometimes because something needs your action. The most common reason by far: it's waiting on information from you.

The letters you'll most likely receive

1. A quarterly declaration reminder (déclaration trimestrielle)

If you receive the RSA or certain other benefits, you must declare your income every three months, even if it's zero. Miss the deadline and your payment is automatically suspended the following month — this is the single most common cause of "my CAF payment just stopped."

2. A suspension notice

States that a payment (often APL housing aid or RSA) has been paused, almost always because a declaration wasn't submitted or a document is missing. It's reversible — submitting what's missing typically restarts payment, sometimes with the missed months paid retroactively.

3. An overpayment letter (indu)

Tells you that you were paid more than you were entitled to, usually after a recalculation based on updated income data, and asks you to repay the difference — sometimes via automatic deduction from future payments. It will state the amount and repayment method.

4. A document request

Asks for proof — a rental contract, payslips, a tax notice (avis d'imposition) — needed to finalise your file. Usually gives a specific number of days to respond via your CAF online account (Mon Compte).

Scary words, decoded

Déclaration trimestrielleThe quarterly income declaration required for RSA and some other benefits — must be filed even at zero income.

InduAn overpayment the CAF says it made and wants back — not a fine, just a recalculation. Some letters use the synonym trop-perçu ("overreceived") instead.

Pièces justificativesSupporting documents — payslips, tax notices, a rental contract — that the CAF needs to verify or finalise your file.

QuittancementConfirmation that a payment has been processed and validated.

APLAide personnalisée au logement — housing assistance, one of the most common payments affected by suspensions.

Mon CompteYour online CAF account — where most declarations and document uploads actually happen, referenced in nearly every letter.

What to actually do

Log into Mon Compte on caf.fr — this is faster than anything by post and shows your real-time status.
If it's a declaration reminder: file it immediately, even if your income was zero — that's still a valid declaration.
If it's a suspension: check exactly what's missing in your account, submit it, and payment usually resumes within the next cycle.
If it's an indu: check the recalculation makes sense; if it doesn't, you can contest it through Mon Compte rather than simply paying without checking.

Frequently asked questions

Why did my CAF payment suddenly stop?

By far the most common reason is a missed quarterly declaration or an outstanding document request — check Mon Compte first, since it usually explains exactly what's needed.

Do I have to repay an indu immediately?

Not usually in one lump sum — the CAF typically deducts it gradually from future payments, though you can also contest the recalculation if you believe it's wrong.

What happens if I miss a déclaration trimestrielle deadline?

Payment is generally suspended the following month until you submit it — filing it, even late, typically restarts payment without further penalty.
