Annual RTB Registration, Late Fees & Penalties.

Annual RTB registration is now mandatory for every Irish tenancy. This page explains the annual fee structure, how late charges are calculated, and the financial risks Dublin landlords face if deadlines are missed. 

What Annual Registration Involves:

Re‑registering the tenancy every 12 months
Confirming rent amount
Confirming tenant details
Updating any changes (rent, occupants, BER, etc.)
Paying the annual RTB fee

Late Fees & Penalties:

Late registration triggers automatic penalties
€10 per month late
Capped at the annual fee
RTB may pursue unpaid penalties
Persistent non‑compliance can escalate to enforcement

Annual RTB Fees 2026:

Standard tenancy: €40 per year
Student-specific tenancies: €20 per year
Multiple tenants: same fee (not per tenant)

Why Irish Landlords Get Caught:

Forgetting the renewal date
Changing tenants mid‑year
Not updating rent changes
Assuming the RTB will “remind you”
Confusing initial registration with annual registration

The Real World Impact for Irish Landlords:

Missing annual registration can invalidate 1) rent reviews, 2) notices of termination, 3) dispute defences. It also exposes landlords to avoidable financial penalties.  See also Registration Requirements for Irish LandlordsMost landlords make mistakes because the RTB rules change frequently — we stay on top of them so you don’t have to.
