Ireland version
How it works
Calculate 2026 Irish LPT using all 31 local-authority adjustments and the 2026–2030 valuation bands, or budget from a separately verified US assessment or UK Council Tax/domestic-rates bill.
This is the Ireland planning view, with monetary inputs and outputs in EUR. A currency label does not establish that a tax rate, construction price, coverage rule or legal limit has been verified locally. The inputs and limitations below describe the actual scope.

Formula
Irish LPT: published 2026 band charge (or high-value formula) × (1 + selected authority adjustment). Manual assessment/bill methods remain separately identified.
Calculations retain numeric precision internally. Displayed values are rounded for readability. Quantities that must be purchased as whole units are rounded up only where the formula explicitly requires it.

Reproducible worked example
The following is a fictional arithmetic example, not a local quote, a verified claimant or a market forecast. Its values are included so the formula can be checked. The form does not automatically confirm any verification checkbox.

Interpreting a changed assumption
Start with one complete scenario and change only one input when diagnosing a difference. Recheck units, the period of every rate, whether an amount is recurring or one-off, and whether a cost is already included elsewhere. A larger calculated benefit is not evidence that an assumption is more likely to occur.
Limitations
- Planning calculation, not a tax return, benefit decision, credit approval or legal opinion. No eligibility is inferred from a numeric result.
- Only the stated tax year and expressly supported rule components are included. Entered amounts require independent verification.
- 2026 LPT band 2; unadjusted charge €235.00; Dublin City Council adjustment 0%.
- Rates verified 2026-09-25. Use value as at 2025-11-01, not today’s market price. The local factor applies 2026-01-01 through 2026-12-31; later annual factors must be checked.
- This is liability before exemptions, deferral, interest, arrears or approved hardship relief. A monthly reserve is not an official payment schedule. Source: https://www.revenue.ie/en/property/local-property-tax/valuing-your-property/valuation-bands-rates.aspx
Frequently asked questions
What does this Property Tax Calculator and Bill Planner result represent?
Calculate 2026 Irish LPT using all 31 local-authority adjustments and the 2026–2030 valuation bands, or budget from a separately verified US assessment or UK Council Tax/domestic-rates bill. It applies the displayed formula to your inputs; it does not infer omitted facts.
Are the starting amounts verified Ireland prices or legal rules?
No. Numeric defaults are illustrative unless an input or dated reference explicitly identifies a researched component. Currency is EUR; local quotes, eligibility and unsupported rules must be entered and verified separately.
What must I check before relying on the result?
Planning calculation, not a tax return, benefit decision, credit approval or legal opinion. No eligibility is inferred from a numeric result. Only the stated tax year and expressly supported rule components are included. Entered amounts require independent verification.
Can I compare or share different assumptions?
Change one assumption at a time and use the browser-local project or share controls. A shared URL contains the encoded input values; do not include information you do not wish to disclose.
