Zoned land tax in Ireland: the dates that decide your bill

Farming a field does not keep it out of the Residential Zoned Land Tax. If your land is zoned for housing, serviced, and on your local authority's map, Revenue charges 3% of its market value every year. The liability date is 1 February. The return and the payment are both due by 23 May.

That catches farms on the edge of towns and villages. Here is how the map, the dates and the way out actually work.

Zoning decides it, not what you do with the land

The zoned land tax is charged where three things are true at once. The land is zoned for residential or mixed use. It is serviced, or capable of being serviced, for housing. And it appears on the annually revised map your local authority publishes by 31 January.

Nothing in that list asks what the land is used for. You can be cutting silage off it in June and liable on it the following February.

Revenue's guidance does set out exclusions. A shop paying commercial rates that serves a nearby residential area sits outside the tax. So does land that is integral to a business running on or beside it. A dwelling already paying Local Property Tax is outside it too.

Farming is not on that list. The Department of Housing describes the tax as a measure to activate zoned, serviced land for housing. Grazing it does not count as activating it.

What does the 3% actually apply to?

Market value, not agricultural value. Land zoned for housing is valued as housing land, which is the whole point of the charge and the reason the numbers land hard.

You work out that value yourself. RZLT is self-assessed, and Revenue lists local estate agents, valuers and property sales websites as sources you can use. A surcharge applies where a site is undervalued, so this is not a corner to cut.

The valuation generally holds for three years. Say your site first fell into the tax in 2025. The same value carries 2025, 2026 and 2027. The next valuation date is 1 February 2028.

One more thing before you budget for it. RZLT is not deductible. You cannot set it against income tax, corporation tax, capital gains tax, USC or the domicile levy. It comes out of after-tax money.

The one-acre trap that catches people who owe nothing

There is a separate obligation for houses on the map.

If your dwelling is on the map and pays Local Property Tax, you do not pay RZLT on it. But the garden and yard enjoyed with it may run to more than 0.4047 hectares — one acre. Then you must still register the property with Revenue.

A farmhouse on the edge of a town clears an acre of yard and garden without anyone thinking about it. Failing to register when you are obliged to carries a €3,000 penalty. Registration is done through the RZLT portal on ROS or myAccount.

What are the dates that decide the bill?

The cycle runs on fixed dates, and most of them fall long before you would ever see a demand.

An Coimisiún Pleanála decides an appeal within 16 weeks of the notice of appeal.

For 2027, the draft map appeared on 1 February 2026 and the submission window shut on 1 April 2026. The final map for 2027 is published on 31 January 2027. Anything on it is liable on 1 February 2027.

Is there a way out if you are farming it?

There has been one. It has needed renewing every year.

Finance Act 2024 let landowners on the 2025 map ask their council to rezone the land. The request had to be made between 1 February and 1 April 2025. Finance Act 2025 did the same for the 2026 map, with the window running 1 February to 1 April 2026.

The Department of Housing spelled out what that request can be. It includes asking the council to change the zoning to reflect the current economic use of the land — which, on a farm, is farming.

Make the request inside the window and you can claim an exemption for that year, where the conditions are met. The council acknowledges it by 30 April and tells you its decision by 30 June. You still register, still file by 23 May, and claim the exemption on the return.

Three things to be clear about:

• The request has to be made again each year, even if you made one before.
• It does not apply where the land is subject to a live planning application or permission for housing.
• A council agreeing to start a rezoning process is not the same as the land being rezoned.

There is no standing exemption for actively farmed land. Whether the route reopens for 2027 rests on Budget 2027, due on 6 October, and the Finance Act that follows it.

What can you still do this autumn?

The 2026 windows are shut. These are not.

1. Look at the draft map for 2027 now. It went up on your council's website on 1 February 2026. The gov.ie RZLT page links all 31 local authority pages in one place. If your ground is on it, a bill is coming on 1 February 2027.
2. Register if you are liable — or if the house-and-acre rule catches you. The €3,000 penalty does not wait for the tax to fall due.
3. Watch Budget day on 6 October. Any extended rezoning route would run off the final map published on 31 January 2027. The last two windows were about two months each.
4. Put 1 February and 1 April 2027 in the diary. That is the draft map for 2028, then the deadline to argue the criteria are not met. Wrong zoning, no services, or the wrong date recorded against the land.
5. Get the value right before you file. It holds for three years, and a surcharge applies if it is too low.

Frequently asked questions

Can I be liable if the field is in grass and declared for BISS?

Yes. Liability follows the zoning, the servicing and the map, not the farming. You declare the parcel for BISS exactly as before, and it has no bearing on whether the same ground sits on an RZLT map.

What if the land should never have been on the map at all?

That is a submission to your council, not a rezoning request, and it runs off the draft map. The deadline is 1 April after the draft map is published, with an appeal to An Coimisiún Pleanála by the following 1 August. It argues the criteria are not met — the zoning, the services, or the date recorded against the land.

Does paying RZLT reduce my income tax or capital gains tax?

No. Revenue's guidance is explicit that RZLT is not deductible for income tax, corporation tax, capital gains tax, USC or the domicile levy. If you sell the site later, the RZLT you paid does not reduce the chargeable gain.

Where to get help

Your local authority owns the map. Revenue owns the zoned land tax. They are two separate conversations and you may need both.

The gov.ie RZLT page carries links to all 31 council RZLT pages and is the quickest way to your county's map. Revenue's RZLT section covers registration, returns, exemptions and deferrals, and its Quick Start Guide runs the whole thing as a flowchart.

Is any of your ground on a map, with a sale, a transfer or a succession plan in view? Talk to your accountant before the next liability date. Unpaid RZLT, and the interest on it, becomes a charge on the land itself.

The bottom line

If any of your ground is zoned for housing and serviced, open your council's zoned land tax map this week rather than next February. The tax does not care that you are farming it. Every way out is tied to a date. The one route that has worked for farmers has needed renewing in each Finance Act so far.
