How to use the Rental Income Tax Calculator

If you rent out a property in Ireland, you're taxed on your profit, not the rent you collect. Working that out by hand means juggling allowable expenses, mortgage interest, wear-and-tear allowances, and then Income Tax, USC and PRSI on top. Our Rental Income Tax Calculator does it in seconds — this guide explains each field so your result is accurate.

Start with the total rent you received for the year, before deducting anything. If you let the property for only part of the year, enter only the rent actually received. For multiple properties you can run the calculator once per property to see each one's profit. But note: the RPRIR relief is one €1,000 maximum per landlord per year, not €1,000 per property — so don't claim it on each run. Your overall Case V income and losses are pooled across properties.

Enter the interest portion of your mortgage for the year — not the capital repayments. Only the interest is deductible, and it has been fully (100%) deductible since 2019 for RTB-registered tenancies. Your lender's annual statement will show the interest charged.

Add up the rest of your deductible running costs for the year and enter the total. Common allowable expenses include:

• property insurance;
• repairs and maintenance (not improvements);
• letting and management fees;
• the RTB registration fee;
• accountancy and certain legal fees;
• advertising for tenants;
• service charges and utilities you pay and don't recharge to the tenant.

Furniture, white goods and fittings aren't deducted in full in the year you buy them. Instead you claim a capital allowance of 12.5% of the cost per year, over 8 years. Enter this year's allowance — that's the cost divided by 8.

You'd claim that €1,000 each year for eight years. If you bought items in different years, add up the allowances still running.

This is the important one for accuracy. Rental profit is "Case V" income — it's stacked on top of your other income (usually your salary), so it's taxed at whatever rate you've already reached. Enter your PAYE salary or employment income here.

If your other income already exceeds the €44,000 standard-rate band, your entire rental profit is taxed at 40%. If you're below it, some or all of the profit may be taxed at 20%. Leave this at 0 only if the rental is genuinely your only income.

The Residential Premises Rental Income Relief is a tax credit worth up to €1,000 for 2026. Toggle it on only if you've confirmed you qualify. The conditions are strict: you must be an individual landlord who owns the residential property on 31 December, is registered with the RTB, has valid tax clearance and is LPT-compliant, files on time, and keeps the property in qualifying residential use. Lettings to a connected person can disqualify it.

Say you're a higher-rate taxpayer (€55,000 salary) with a rental property earning €18,000 a year. Your expenses are €4,000 mortgage interest, €2,000 other costs, and €1,000 wear & tear, and you claim RPRIR:

So of €11,000 profit, about €4,196 goes in tax and you keep roughly €6,804 — an effective rate of about 38% on the profit. The calculator shows this full breakdown live as you type.

The calculator gives you an estimate — to declare the income you file a self-assessment return with Revenue:

• 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 generally register for self-assessment and file a Form 11 through ROS.
• The deadline is 31 October each year, with an extension to mid-November if you file and pay through ROS online.
• Late filing carries a surcharge of 5% or 10% of the tax due, plus interest.

Our Revenue myAccount checklist walks through the return process step by step.

Does the calculator handle joint ownership?

Not directly — it assumes a single individual. If you own a property jointly (for example with a spouse or civil partner), the profit is usually split by ownership share, so you'd run the calculator on your share of the rent and expenses, using your own other income.

What if my expenses are higher than my rent?

If allowable expenses exceed your rent, you make a rental loss, and the calculator shows zero taxable profit. Irish rental losses can be carried forward against future rental profits (not against your salary or other income), and carried-forward losses also affect your RPRIR. This calculator does not model prior-year losses — if you have them, factor them in separately and keep a record for your Form 11.

Why is my rental profit taxed so heavily?

Because it stacks on top of your salary. If you're already a higher-rate taxpayer, every euro of rental profit is taxed at 40% and may also be subject to USC and PRSI depending on your circumstances — a combined marginal rate that can exceed 50%. That's why claiming every allowable expense matters.

Is the €1,000 landlord relief the same as the Rent Tax Credit?

No. The RPRIR is for landlords, reducing tax on rental income. The Rent Tax Credit is for tenants who pay rent. They're separate reliefs — don't confuse the two.
