Owning Irish Property as a Non-Resident 2026: Non-Resident Landlord Withholding, CGT and LPT

Letting Irish property as a non-resident landlord: the legal framework

Once you cease to be ordinarily resident in Ireland, any rental income from an Irish-situated property remains taxable in Ireland under Section 25 TCA 1997. Ireland has primary taxing rights on Irish real estate income under nearly every Double Taxation Agreement it has signed (Article 6, Income from Immovable Property). Your destination country may also tax the rent but typically grants a credit for the Irish tax paid. Failing to declare Irish rental income in either country is one of the most common emigrant compliance issues.

The mechanics involve four moving parts: the Form NRL (Non-Resident Landlord) withholding regime, the annual Form 11 self-assessed return, Local Property Tax (LPT), and the eventual Capital Gains Tax position when the property is sold. Each must be set up before tenants take occupancy or the situation becomes administratively expensive to fix.

The 20% withholding mechanism: tenant or collection agent

Under Section 1041 TCA 1997, when a tenant pays rent directly to a non-resident landlord, the tenant is legally required to deduct 20% of the gross rent and remit it to Revenue. The tenant accounts for the withholding via their own Form 12 or Form 11 and provides the landlord with an annual Form R185 confirming the tax deducted. The landlord then claims the withheld 20% as a tax credit on the Form 11 self-assessed return. Most tenants have no idea about this obligation and most non-resident landlords do not warn them.

The cleaner alternative is to appoint a collection agent — usually a property management company, an Irish-resident accountant, or a relative in Ireland willing to act as agent. The collection agent is treated as the chargeable person on the rent: the tenant pays the agent gross, the agent files Form 11 each year on the landlord’s behalf, and the agent is jointly liable for the tax. Most reputable Irish letting agents (DNG, Sherry FitzGerald, Lisney, REA, etc.) include the collection-agent service for an additional fee of typically 1-2% of rent on top of management fees.

Form NRL registration and Revenue notification

Whichever option you choose, register the arrangement with Revenue before tenancy begins. The landlord (or agent) submits Form NRL via myAccount or ROS, and the agent is named on Revenue’s records. The tenant then receives written notice that they need not deduct withholding because a collection agent is in place. Without the formal collection-agent appointment, Revenue may pursue the tenant for failure to withhold.

Computing taxable rental profit: allowable deductions

Taxable rental profit is gross rent received minus allowable expenses. Allowable expenses include: mortgage interest at 100% of eligible interest (post-2017 reform restored full deductibility for residential lettings registered with the RTB), property management and letting agency fees, RTB registration fees, repairs and maintenance (not improvements, which are capital), insurance, accountancy and tax-agent fees, advertising of vacancy, and a wear-and-tear capital allowance of 12.5% per year over 8 years on furniture and white goods.

Capital improvements (a new kitchen, an extension, a major roof job) are not deductible against rent but added to the property’s base cost for eventual CGT calculation. Keep all invoices: Revenue increasingly audits non-resident landlord returns and the burden of proof is on the taxpayer.

RTB registration: a separate but mandatory step

The Residential Tenancies Board (RTB) requires every residential tenancy to be registered within one month of commencement. Registration costs 40 EUR per tenancy (90 EUR if late). Without RTB registration, the landlord cannot deduct mortgage interest against rental income — a potentially huge tax penalty. Renew registration whenever the tenancy is renewed or new tenants take over. RTB also handles dispute resolution between landlords and tenants and is the relevant body for security deposit disputes.

The Rent Pressure Zone (RPZ) regime, currently extending across most urban areas, caps annual rent increases at 2% (or HICP inflation, whichever is lower). Setting rent above market on a new tenancy can attract RTB enforcement action. Use the RTB rent index database (rtb.ie) to verify market and RPZ-permitted levels before agreeing rent with a new tenant.

Eventual sale and the 33% CGT exposure

When you eventually sell the rental property, 33% CGT applies to the gain. As discussed in our property sale guide, Principal Private Residence Relief (PPR) covers only the periods when the property was your main residence plus the final 12 months. Years when the property was let are chargeable. Compute the chargeable fraction as: chargeable months over total months of ownership, applied to the gross gain.

Also remember the CG50 tax clearance certificate requirement for residential disposals over 500,000 EUR. Without it, the buyer’s solicitor must withhold 15% under Section 980 TCA 1997, refunded only after CGT is paid and CG50A is filed. Plan well before sale, ideally 8-12 weeks ahead.

The destination-country dimension

Your destination country will tax the same rental profit, with credit relief for the Irish tax paid. Most countries compute taxable rental profit on broadly similar rules (gross rent minus allowable expenses) but may differ on capital allowances, mortgage interest treatment, and depreciation rules. Common surprises: Germany taxes rent at marginal income tax rates with strict depreciation rules; France imposes 17.2% social charges on top of income tax for non-EU residents; Spain has a flat 24% on gross rent for non-EU residents (19% for EU residents with deductions).

Always declare Irish rental profit in your destination return at the gross-rent level and claim the foreign tax credit for Irish tax paid. Keep the Irish Form 11 acknowledgement and computation as supporting evidence; some destination tax authorities (German Finanzamt, French SIE, Spanish AEAT) request copies during compliance reviews.

Practical 60-day plan before letting begins

Day -60: Decide between collection agent and tenant withholding. Negotiate fees with letting agent if going the agent route. Verify mortgage lender allows letting (some Irish lenders require consent to let, with possible interest rate increase).

Day -30: Register collection-agent arrangement with Revenue via Form NRL. Update myAccount/ROS with foreign address. Set up SEPA-compatible IBAN to receive net rents.

Day -7: Sign letting agency contract. Brief tenant in writing about rent, deposit, RTB registration. If using tenant-withholding model, give written notice in lease that 20% must be withheld and remitted.

Day 0 (tenancy starts): RTB registration filed within one month. First rent received. Collection agent forwards net amount.

Day +30: Confirm RTB registration receipt. Verify Revenue notification of NRL setup is acknowledged. Set calendar for 31 October Pay & File deadline next year.

Annual: File Form 11 by 31 October following the tax year. Pay preliminary tax for current year and balance for prior year. File destination-country return claiming foreign tax credit.
