Unrevised rent in France: can you catch up past years?
No. A forgotten revision cannot be caught up: the new rent applies from the day of your request, never before. And a request made more than a year after the date set in the lease no longer counts for that year.
Key points
Nothing before the request — The months paid at the old rent stay with your tenant.
One year to ask — After that, the law treats you as having given up that year’s revision.
How much have you already lost?
Rent, date of the last revision, index quarter: the amount lost and the deadline for your request, no sign-up.
My rent hasn’t changed since 2023: what is left?§
Each year of the lease opens a revision, and each one has its own one-year deadline. Example: lease signed on 1 February 2023 at €750, 4th-quarter index, never revised.
1 Feb. 2023
Lease signed at €750.
1 Feb. 2024
First possible revision. No request before 1 February 2025: it is lost.
1 Feb. 2025
Second revision. No request before 1 February 2026: lost too.
1 Feb. 2026
Third revision. A request is still possible until 1 February 2027.
1 Oct. 2026
Request sent. The rent becomes €755.91 from that day.
Between 1 February and 1 October 2026, 8 months at €5.91 less: €47.28 that cannot be recovered. The 2024 and 2025 revisions give rise to no back rent.
On forums you still read that a landlord can claim five years of revisions. That was the rule before the Alur law of 24 March 2014, which removed the retroactive effect and cut the deadline to one year.
Which index for a revision requested today?§
The quarter is the one written in the lease. If there is none, it is the quarter of the last index published by INSEE on the signing date.
Can the lost years count in the new rent?§
The calculator follows the first reading, the one behind the service-public.fr and ANIL formula. In both cases, no past month is caught up.
When is no revision possible?§
The lease has no revision clause
Without this clause, the rent is not revised during the lease.The home is rated F or G
No revision for a lease signed, renewed or tacitly renewed since 24 August 2022 (1 July 2024 in Guadeloupe, Martinique, French Guiana, Réunion and Mayotte).It is a bail mobilité
The rent is not revised for the term of this short furnished lease.
Which date counts for the request?§
The law only speaks of “expressing the wish” to revise, without requiring any form. The new rent runs from the date of this request, and a revision takes place only once a year.
Service-public.fr mentions a registered letter with acknowledgement of receipt, which fixes that date.
How much have you already lost?
Rent, date of the last revision, index quarter: the amount lost and the deadline for your request, no sign-up.
