What LPT actually charges you on your home
Local Property Tax is a self-assessed charge on the market value of your home, collected by Revenue on behalf of your county or city council. It funds local services: street lighting, parks, libraries, fire and emergency cover. Every residential property owner is liable, and you set your own valuation, which Revenue can challenge if it looks well off the mark. This tool takes the simplest route through the rules. It applies a base rate of about 0.1029 percent to your declared value, then lets you nudge the result up or down by the local adjustment factor. On a €400,000 home that base rate produces an annual charge of roughly €412, or about €34 a month.
The local authority can move your bill by 15 percent
Here is the part most people overlook. Each of the 31 local authorities votes every year on whether to vary the standard LPT rate, and they can move it within a band of plus or minus 15 percent. Several Dublin councils have historically shaved the charge by the full 15 percent, while others leave it at the base rate or raise it. That single decision is the difference between a comfortable saving and a heavier bill, so the adjustment field here is not a rounding detail. If your council applies a 15 percent reduction to a €525,000 valuation, the base charge of about €540 drops to roughly €459 for the year. Always check your own council’s published factor before you trust a headline figure.
A €400,000 home, step by step
Take a standard three-bed in a commuter town valued at €400,000, in a council that has left its rate at the standard level, so the adjustment is zero. The maths runs in two lines.
The chart below shows how the same valuation produces different annual bills once the council vote is applied, from a 15 percent reduction through to a 15 percent increase.
Where this estimate parts company with Revenue’s bands
One honest caveat. Revenue does not bill LPT off a single flat percentage. It groups homes into valuation bands and charges a fixed amount per band, with a percentage formula only kicking in on higher-value properties. This calculator uses a clean flat rate on your exact value, which tracks the band charges closely for typical homes but will not match Revenue to the last euro, especially near a band boundary. Treat the output as a reliable planning figure rather than your final liability. A common mistake is undervaluing a home to land in a cheaper band, then facing a clawback when the property sells and the real price is on the public record.
Do I pay LPT on a property I rent out?
Yes. The owner is liable, not the tenant, so a landlord pays LPT on each residential property they hold on the liability date. It is not a deductible expense against rental income in the way mortgage interest is, so factor it into your gross yield separately.
What happens if I miss the payment?
Revenue can apply interest and penalties, and it has strong collection powers, including deduction at source from your salary or occupational pension and a surcharge on your income tax return. LPT arrears also surface as a charge on the property, which has to be cleared before you can sell. Paying by direct debit or a single annual debit avoids the whole problem.
