Rental Income Tax Calculator.
Renting out a property in Ireland? You're taxed on your profit, not your rent. This calculator works out your net rental profit after expenses, then your Income Tax, USC and PRSI — instantly.
100% of qualifying mortgage interest on an RTB-registered rental has been deductible since 2019 (subject to conditions). Capital repayments are not.
Furniture, white goods and fittings are written off at 12.5% a year over 8 years — e.g. €8,000 of furnishings gives €1,000 a year.
Up to €1,000 off your Income Tax for 2026 if you stay in the rental market — capped at 20% of your rental profit.
Rental profit is added on top of your salary, so it's taxed at your highest rate — 20% or 40%.
Rental Tax Calculator
Annual figures for one property.
Total rent received for the year before any expenses.
Interest only — not capital repayments. 100% deductible since 2019 if RTB-registered (subject to conditions).
Insurance, repairs, management/letting fees, RTB fee, accountancy, advertising, service charges. (Not LPT — that's not deductible.)
This year's 12.5% capital allowance on furniture and fittings (cost ÷ 8).
Your gross PAYE salary or employment income. This decides whether your rental profit is taxed at 20% or 40%. The calculator shows tax on the rental profit on top of this, and does not apply your personal tax credits — so if rent is your only income the Income Tax shown may be higher than you'd actually pay once credits are applied.
Only tick Yes if you've confirmed you qualify — RPRIR has strict conditions (RTB registration, tax clearance, LPT compliance, ownership at 31 Dec, no connected-person letting) and can be clawed back. Reduces Income Tax only, one €1,000 max per landlord per year.
Estimate only. Assumes a single individual, standard bands, and rental profit taxed on top of your PAYE income. The USC surcharge calculation assumes the rental profit entered here is your only non-PAYE income. It does not apply your personal tax credits or carried-forward rental losses. Your PRSI class and actual liability depend on your circumstances.
How rental income tax works in Ireland
Rental income is "Case V" income. You're taxed on your net profit — rent minus allowable expenses — added on top of your other income.
The calculation flow
Gross rent − allowable expenses − wear & tear = taxable rental profit. That profit is then charged to Income Tax (20% or 40%, depending on your total income), USC, and PRSI where applicable. PRSI treatment depends on your employment/self-employment status, age and PRSI class, so the calculator uses an indicative 2026 rate only. The RPRIR landlord relief, if you qualify, comes off the Income Tax at the end.
What you can deduct
Allowable expenses include mortgage interest (100% since 2019, if RTB-registered), property insurance, repairs and maintenance (not improvements), letting and management fees, the RTB registration fee, accountancy fees, and advertising for tenants. Note that Local Property Tax (LPT) is not deductible. Furniture and fittings are handled separately as wear and tear — 12.5% of the cost per year over 8 years.
What you can't deduct
Capital repayments on your mortgage (only the interest counts), property improvements or extensions (these are capital, and may reduce CGT on a future sale instead), and your own labour. Pre-letting expenditure and Rent-a-Room relief have their own separate rules not modelled here.
The RTB registration rule
Mortgage interest is only deductible if your tenancy is registered with the Residential Tenancies Board (RTB). If it's not registered for a period, the interest deduction is disallowed for that period — so registration directly affects your tax bill.
How and when to declare
How you declare rental income depends on the amount. PAYE employees with net rental income below €5,000 can generally declare it through their Income Tax Return in myAccount. If net rental income exceeds €5,000 (or you otherwise cross the self-assessment thresholds), you register for self-assessment and file a Form 11 through ROS. Returns are filed by 31 October each year — with the ROS online extension to mid-November. Late filing carries surcharges of 5% or 10% plus interest. See our Revenue myAccount checklist for the process.
Frequently asked questions

It assumes a single individual and does not account for joint assessment, multiple properties, pre-letting relief, Rent-a-Room relief or your personal tax credits. It is not tax advice.
