Rental Income Tax Ireland 2026: Landlord's Complete Guide
Being a landlord in Ireland comes with tax obligations you can't ignore. Whether you own a single rental property in Dublin or manage multiple units in Cork and Galway, understanding rental income tax is essential for staying compliant and maximizing your profits. This 2026 guide covers everything from tax rates and allowable expenses to RTB registration and Revenue deadlines.
💰 How Rental Income Tax Works in 2026
Rental income is treated as part of your total taxable income in Ireland. Here's the breakdown:
Tax Rates
- Standard rate: 20% (if your total income is below the cut-off point)
- Higher rate: 40% (on income above the threshold)
- USC: 0.5% to 8% depending on income level
- PRSI: 4% for most landlords
Net vs. Gross Income
You pay tax on your net rental income (gross rent minus allowable expenses), not the total rent collected. This is crucial for accurate tax planning.
Example:
• Gross annual rent: €18,000
• Allowable expenses: €6,000
• Net taxable income: €12,000
• Tax @ 40%: €4,800
• Plus USC and PRSI
