irish rental income tax calculator

How this Irish rental income tax calculator works

Irish rental income is generally taxed as part of your total income. In practical terms, this means your rental profit can be taxed partly at the standard income tax rate and partly at the higher rate, depending on how much of your lower tax band is already used by salary, self-employment income, pension income, or other taxable earnings.

This calculator follows a straightforward model:

• Net rental profit = Gross rent − Allowable expenses − Mortgage interest
• Income tax = 20% on available standard-rate band + 40% on remainder
• PRSI = Net rental profit × PRSI rate
• USC = Net rental profit × USC rate entered

Then it combines those amounts to estimate your total tax and your after-tax rental profit.

What counts as rental income in Ireland?

Rental income usually includes all amounts received from tenants for use of the property. That can include the base rent and, in some cases, additional payments connected with occupancy. If you hold a residential investment property, you should keep clear records for each payment period, especially if there are mid-year rent changes, vacancies, or tenant turnover.

Typical deductible expenses (subject to Revenue rules)

• Repairs and maintenance (not capital improvements)
• Insurance premiums on the rental property
• Letting and management fees
• Accountancy fees related to rental accounts/tax returns
• Mortgage interest (where qualifying conditions are met)
• Other qualifying running costs directly related to letting

Not all property spending is deductible in the year incurred. Capital upgrades and certain once-off costs may be treated differently. Always classify costs carefully.

Why your other income matters

In Ireland, rental profit is added to your taxable income. If your salary already uses most or all of your standard-rate band, your rental income may be taxed largely at 40% income tax before PRSI and USC are added. That is why two landlords with the same rental profit can have very different net outcomes.

Quick example

If your net rental profit is €10,000 and you only have €2,000 left in your standard-rate band:

• €2,000 taxed at 20%
• €8,000 taxed at 40%
• Plus PRSI and USC on the rental profit

This is exactly the kind of split the calculator handles automatically.

Common mistakes landlords make

• Using gross rent instead of net profit: tax is typically based on profit after qualifying deductions.
• Forgetting PRSI and USC: many people estimate income tax only and understate total liability.
• Assuming one fixed tax rate: rental income often spans multiple effective rates.
• Poor record-keeping: missing invoices and receipts can reduce valid claims.
• Ignoring annual tax return deadlines: late filing can trigger penalties and interest.

How to use this estimate responsibly

This tool is best used for planning and scenario testing. For example, you can check how your tax changes if:

• Interest costs rise or fall
• Allowable expenses increase (maintenance year)
• Your salary changes and reduces available 20% band
• You buy another rental property and aggregate profits increase

For official filings, confirm assumptions against current Revenue guidance, especially for relief eligibility, USC treatment, and any updates to rates or thresholds.

Final thoughts

An Irish rental property can produce strong long-term returns, but tax can materially affect cash flow. A simple annual estimate helps you avoid surprises, budget for liabilities, and make better decisions about rent levels, financing, and maintenance timing.

If you want high confidence before filing, consider getting a property-focused accountant to review your numbers and ensure compliance with the latest Irish tax rules.
