Claiming every allowable deduction is the single most effective way to reduce your rental income tax bill. Here is the full list for 2026.

What Counts as a Repair vs an Improvement?

This distinction catches many landlords. A repair restores something to its original condition and is fully deductible in the year paid. An improvement enhances the property beyond its original condition and is treated as capital expenditure (not deductible as a revenue expense, but may qualify for capital allowances or CGT enhancement expenditure).

Examples of repairs: replacing a broken boiler with a similar model, repainting walls, fixing a leaking roof, replacing damaged flooring like-for-like.

Examples of improvements: adding an extension, installing a new kitchen where none existed before, converting an attic into a bedroom, upgrading single glazing to double glazing.

Record Keeping Tips

• Keep all invoices and receipts for at least 6 years
• Maintain a property file for each rental property
• Record the date of every expense and the property it relates to
• Keep RTB registration confirmations and renewal receipts
• Save bank statements showing mortgage payments
• Note vacancy periods with dates and reasons

Multi-Property Aggregation

All rental income and expenses are aggregated on a single Form 11. You cannot offset a rental loss against employment income, but you can carry forward losses to offset against future rental profits. Our Property Investor Pack (EUR 99) handles multi-property calculations with per-property and aggregate views.
