- Mix up personal and rental costs
If you want to keep more of your rental earnings, you need to learn how to avoid taxes on rental income without breaking any rules.
Claim These Key Expenses to Cut Your Irish Rental Tax
The first step is to reduce your taxable profit. You can do that by claiming all valid expenses linked to your rental property.
The main expenses include these:
- Mortgage interest (only the interest part, not repayments)
- Repairs and maintenance (routine work, not upgrades)
- Letting agent or property management fees
- Property insurance
- Legal and accounting fees (only for rental matters)
- Furniture and fittings wear and tear (for furnished homes)
These are 100% legal deductions. They lower your taxable rental income and, in turn, reduce the tax you owe.
⚠️Alert: Keep receipts and records for every expense. Revenue may ask for proof.

Turn Rental Losses Into Future Tax Savings the Smart Way
Sometimes, rental costs go above rental income. In that case, you have a rental loss. Don’t ignore it.
Ways to manage it:
- Carry it forward to reduce tax on future rental income
- Offset it against profits from other rental properties
- Use foreign rental losses only against foreign rental gains
This is a smart long-term move if you want to know how to avoid taxes on rental income across multiple years.
Offset Rental Losses and Save on Future Tax Bills Legally
If your expenses are higher than your rental income, you have a rental loss. Don’t ignore it. You can carry this loss forward and use it to reduce tax on future rental income. If you own more than one property, you can offset the loss against profits from another rental. For losses from foreign rentals, you can only use them against foreign rental gains.
This helps you lower your tax over time. This is a smart long-term move if you want to know how to avoid taxes on rental income across multiple years. Keep records each year so you don’t miss out when filing your tax return.
Long-Term Tax Benefits of Owning Rental Property Through a Company
Using a company to own rental property can cut your tax bill. In Ireland, corporate tax is 12.5%. That’s much lower than the personal tax rate, which can go up to 40%. If you own more than one property, this option can save money. But it also brings extra costs. You must pay for setup, yearly accounts, and legal compliance.
You also need to follow strict company rules. This is not the best choice for everyone. But long-term landlords may benefit. Always compare both options before you decide. Talk to a tax advisor if you’re unsure. Below is a simple comparison to help you understand the difference.
