Airbnb and Short-Term Letting: How Your Tax Works

Aonghus Sammin15 September 20264 min read

Income you earn from Airbnb and other short-term lettings is taxable in Ireland and must be declared on your income tax return. If you let a room in your own home you may be able to use Rent-a-Room Relief to earn up to €14,000 a year tax-free.

Is short-term letting income taxable?

Yes. Short-term lettings are treated as rental income, so you pay income tax, USC and PRSI on your profits. You must register for self-assessment, file an annual return and keep records of your income and expenses.

When Rent-a-Room Relief applies

If you let a room (or rooms) in your principal private residence, Rent-a-Room Relief lets you earn up to €14,000 a year tax-free. Short-term guest accommodation in your home can qualify in some cases, but a self-contained unit let on a short-term basis generally does not. If you exceed €14,000, the full amount becomes taxable.

What expenses can you claim?

  • A proportion of mortgage interest, insurance and utility bills.
  • Repairs and maintenance related to the letting.
  • Cleaning, laundry and platform fees.
  • Local property tax (where deductible).

Frequently asked questions

Do I have to declare Airbnb income?

Yes, unless it is covered by Rent-a-Room Relief and your gross income is €14,000 or less. Above that, you must declare and pay tax on the full amount.

Can I use Rent-a-Room Relief for a whole apartment?

Generally no. A self-contained unit that is separate from your home and let short-term does not qualify for Rent-a-Room Relief.

What records should I keep?

Keep records of your bookings, income, platform fees and expenses for six years.
