How this Ireland rental income tax calculator works
If you rent out residential property in Ireland, your rental profit is usually taxed under Case V. In plain English: you start with gross rent, subtract allowable deductions, and then apply the taxes that may apply to you (income tax, USC, and PRSI).
This calculator helps you estimate that quickly. It is especially useful for landlords who want to understand expected tax before filing, compare properties, or plan cash flow for the year ahead.
What to include in each input
1) Gross annual rent received
Enter the full rent actually received in the tax year, before any costs are deducted. Include all months and all tenants for the property.
2) Allowable non-finance expenses
Typical examples may include:
- Repairs and maintenance (not capital improvements)
- Insurance premiums
- Letting or management fees
- RTB registration fees and certain administrative costs
- Accountancy fees related to rental accounts
3) Deductible mortgage interest
Mortgage interest on qualifying residential rental property is generally deductible, subject to compliance conditions and Revenue rules. Enter only the amount you believe is deductible for the period.
4) Capital allowances and loss relief
If you are entitled to wear-and-tear/capital allowances or are using rental losses carried forward from prior years, include those values in the relevant fields.
Estimated taxes included
- Income Tax: calculated at your chosen marginal rate (20% or 40%).
- USC: optional; entered as an estimated effective rate for rental profit.
- PRSI: optional 4% toggle.
Because USC is banded and depends on total income profile, this tool uses your input rate rather than a full personal tax model. That makes it fast, while still being useful for planning.
Worked example
Suppose you receive €24,000 rent, have €3,500 allowable expenses, €4,000 mortgage interest, and €1,000 capital allowances:
- Taxable rental profit = €24,000 - (€3,500 + €4,000 + €1,000) = €15,500
- At 40% income tax, income tax = €6,200
- If USC is 4.5%, USC = €697.50
- PRSI at 4% = €620
- Total estimated tax = €7,517.50
Your actual return can differ depending on reliefs, credits, residency, and whether the property is owned personally or through a company.
Common landlord tax mistakes to avoid
- Mixing up repairs (usually deductible) with improvements (often capital in nature).
- Forgetting to track all eligible expenses across the year.
- Using gross rental cash flow as “profit” without adjusting for allowable deductions.
- Ignoring PRSI/USC when budgeting for tax due dates.
- Not retaining records and invoices in case of Revenue review.
Practical tips for better rental tax planning
Keep a monthly property ledger
Track rent in, costs out, and receipts every month. This makes year-end filing much easier and reduces surprises.
Run scenarios before rent changes
Small changes in rent or costs can materially affect after-tax return. Use the calculator to test “what if” cases before you decide.
Review your USC estimate annually
USC exposure changes with your wider income, so update that rate as your circumstances change.
