Over 18,000 Local Property Tax (LPT) returns were submitted today as of 12pm, ahead of the 5.30pm deadline.
Property owners are required to file updated valuations for their homes to ensure they are in the correct tax bracket in the coming years.
The deadline for submissions was originally set for last Friday, however Revenue extended the deadline to this evening.
Since the extension was announced, over 115,000 returns have been submitted.
This is the first LPT revaluation since 2021, and Revenue acknowledged that some property owners may need help completing their return.
It said the LPT helpline is in high demand, with 7,000 calls answered daily over the past week.
"Property owners are encouraged to continue using all channels of communication with Revenue, including both the telephone helpline and myEnquiries if they have queries," Revenue said in a statement.
"Revenue also reminds property owners that the quickest and easiest way to submit their LPT Return is online via myAccount, ROS, or the LPT Online Portal."
Revenue is working through 100,000 pieces of correspondence, including postal queries and paper returns.
It said property owners who have submitted a query to Revenue through MyEnquiries, by post, or through other correspondence about their 2026 LPT obligations will be treated as compliant if they file their return promptly once they receive a response.
"This pragmatic approach ensures that anyone engaging with Revenue ahead of the deadline and following up promptly is considered compliant," Revenue said.
Revenue's LPT Helpline is open until 4.30pm this afternoon on 01 738 3626.
