Finance (Local Property Tax) Act 2012 section 21

Notification of local adjustment factor to the Revenue Commissioners

Section 21 sets out the obligation on a local authority to notify Revenue of any variation to the basic rate of local property tax, including the form, deadlines and effective date of such notification.

• Where a local authority resolves to vary the basic LPT rate, it must notify Revenue of the percentage variation in the form and manner Revenue specifies.
• The notification must be sent in the same year the resolution is passed, by 31 August if a valuation date falls in that year, or by 15 October in any other year.
• Once Revenue has been properly notified, the varied rate takes effect from the liability date in the year the notification is sent.
• Failure to notify Revenue within the prescribed deadlines means the variation cannot take effect for that year.
