Around 30% of households liable for the Local Property Tax have filed their return, ahead of the deadline which is just over a week away.
Revenue said around 95% of those returned were filed online in either My Account, ROS or the LPT Online Portal.
The deadline for filing is 7 November.
"Before submitting the return, you need to determine the current market value of your property," reminded Katie Clair, Head of Revenue's LPT Branch.
"Then, when submitting the return, you need to select the valuation band appropriate to your property's market value and confirm how you will pay your LPT for 2022," she added.
Revenue said its LPT Helpline is extremely busy.
In recent days, the number of calls received per day has exceeded 10,000.
Ms Clair shared some information for property owners who may have been trying to contact the LPT Helpline.
"The busiest time for calls coming through to our LPT Helpline is between 9.30 and 11.30 each morning.
"If you are having difficulties getting through to us, please try again later in the day if you can," she suggested.
Ms Clair said if you haven't received a letter about your LPT in the post, it may be in your 'My Documents' in 'myAccount' or in your 'ROS Inbox'.
"We know that some property owners may not have received a letter, for example, where the property was not on the LPT register.
"These property owners still need to do three things by the 7 of November - value their property, submit their LPT return and indicate on the return how they will pay their LPT for 2022," she said.
If your property is not currently registered with Revenue, Ms Clair said you can register it yourself by clicking on the 'Register New Property’ link on the Property Services Card in myAccount or in the Other Services section on the ROS homepage.
Revenue said they expect that some property owners will determine that their property falls into a different valuation band than the valuation band indicated on their online valuation guide or the valuation band used for the purposes of their Notice of LPT Estimate.
Where this is the case, you do not need to contact Revenue.
"All you need to do is select the relevant valuation band that applies to your property’s market value when submitting your LPT Return," Ms Clair explained.
