How to Declare Airbnb Rental Income to Revenue in 2026

You made money hosting on Airbnb this year, and now Revenue wants their cut - there's no way around it, and no version of "sure it's only a few nights" that changes the rule. Instead of guessing at tax forms in October, work out the classification now, register the right way, and file before the deadline catches you out.

Sos Stays manages short lets across the Boyne Valley, Louth, Meath and the Mourne coast, and this exact paperwork lands on our desk every year for landlords we work with - so the steps below are the ones that actually get used, not the theory. If you're weighing up whether to self-manage or hand a let over to someone else, Sos Stays is worth a look before you commit to doing all of this yourself every year.

TL;DR

  • Airbnb and other short-term letting income in Ireland is taxed under Case IV as other income, not as rental income under a lease.
  • Use myAccount and Form 12 if net non-PAYE income is under €5,000 and gross is under €30,000; otherwise register for ROS and file Form 11.
  • Rent-a-room relief, worth up to €14,000, does not cover income from guests booked for stays under 28 days through a platform.
  • The return and payment deadline is 31 October the year after you earned the income, later if you file and pay through ROS.
  • Late filing triggers a Revenue surcharge on top of the tax owed, calculated as a percentage of your total liability.

Why this matters

Revenue has been matching Airbnb host payout data against tax returns for years now, and 2026 is no different - the platforms report host earnings, and undeclared income gets flagged. Getting the classification wrong isn't a small clerical slip either: claim rent-a-room relief on guest bookings when you shouldn't have, and you could owe tax, interest and a surcharge on income you thought was covered.

The upside is that once you know which form applies to you, this is a twenty-minute job each year, not a crisis every October.

Before you start

  • A PPS number registered for tax with Revenue - if you've never filed before, you'll need to register through myAccount or ROS first.
  • A record of every payout from Airbnb, Booking.com or direct bookings for the tax year, plus receipts for cleaning, linen, platform fees and any other costs directly tied to the letting.
  • The gotcha: if you've been claiming rent-a-room relief on a spare room you also list on Airbnb, that relief generally does not extend to income from guests booked through a platform for short stays - sort this out before you file, not after.

Classify the income correctly

  1. Work out whether you're renting under a lease (a long-term tenant with a tenancy agreement) or hosting short-stay guests through a platform. Long-term lets are usually Case V rental income. Airbnb-style bookings, where there's no tenancy created, are generally taxed under Case IV as miscellaneous or other income.
  2. If you're providing hotel-style extra services - daily cleaning, breakfast, changeover between guests multiple times a week - Revenue may treat this as a trade, taxed under Case I. Most single-property Airbnb hosts sit in Case IV.
  3. Note down which category applies before you touch a form. Expected result: you know whether you're filling in a rental panel or an "other income" panel later.

Register with Revenue the right way

  1. If you already file a Form 11 through ROS because you're self-employed or a chargeable person for other reasons, you don't need to register again - you'll just add this income to your existing return.
  2. If this is new income and you're a PAYE employee with no other filing obligation, sign in to myAccount and check your gross and net non-PAYE income for the year against the €30,000 and €5,000 thresholds.
  3. Under those thresholds, stay in myAccount and use Form 12. Over them, you need to register for self-assessment and file through ROS using Form 11 instead.
  4. Expected result: you know which system you're filing in before you open a return.

File the correct form: Form 12 or Form 11

  1. In myAccount, go to PAYE Services, then Review your tax, select the relevant tax year, and click Complete Income Tax Return.
  2. Look for the Other Income section and enter your Airbnb income there rather than under any rental or PAYE panel - this is the Case IV income you classified earlier.
  3. In ROS, open your Form 11, go to the Other Income panel, and enter the amount under the line covering income not otherwise returned, then deduct allowable expenses on the same panel.
  4. Deduct only costs that are wholly and directly tied to earning the income - cleaning, linen, platform service fees, a fair apportionment of utilities for the let period. Expected result: your net Case IV income figure is calculated and ready to submit.

Pay by the deadline

  1. Note the standard deadline: returns and payment are due by 31 October the year after you earned the income - income from 2026 is declared by 31 October 2027.
  2. If you both file and pay through ROS, Revenue usually extends this into mid-November - check the exact date each year on Revenue's site rather than assuming it repeats.
  3. If you're newly self-assessed, you'll also owe preliminary tax for the current year alongside the balance for the year just ended.
  4. Expected result: return submitted, tax paid, no surcharge.

Track income as bookings land, instead of scrambling every October

Rather than reconstructing a year of payouts from memory in September, log each Airbnb payout into a simple spreadsheet the week it lands, with the date, amount and any expense receipt attached. Do this whenever a booking is confirmed and paid out, not just at year-end - by the time your filing window opens, the total is already sitting there waiting to be typed in.

Troubleshooting

My Airbnb income isn't showing up on my Statement of Liability. myAccount doesn't pull in platform payout data automatically - you have to add it manually under Other Income every year.

I'm not sure if I need Form 11 or Form 12. Check your gross and net non-PAYE income against the €30,000 and €5,000 thresholds - under both, Form 12 in myAccount; over either, Form 11 through ROS.

I claimed rent-a-room relief on my Airbnb room last year. Speak to Revenue or an accountant about amending the return - guest bookings through a platform generally don't qualify, and this needs correcting before it compounds.

I missed the 31 October deadline. File as soon as possible - a surcharge applies on top of the tax due, and it gets worse the longer the return is outstanding.

I don't know what expenses I can claim. Stick to costs directly and wholly related to the letting - cleaning, linen, platform fees, a fair share of utilities for the letting period - and keep every receipt for six years.

Customize your workflow

If you're letting through Fáilte Ireland's Short-Term Letting Register requirements as well as filing with Revenue, treat these as two separate obligations that both need attention each year, not one combined task. And if the admin side of hosting - bookings, cleaning schedules, guest messages, and the tax paperwork behind it all - is eating more time than the income justifies, a commission-based management arrangement is worth pricing out before your next tax year starts.

One last thing

The detail that catches most first-time Airbnb hosts isn't the form - it's the rent-a-room relief mix-up. Plenty of people list a spare room, assume the €14,000 relief covers it because it's their own home, and only find out otherwise when a return gets queried. Sort the classification first, and the rest of this is paperwork, not a problem.

FAQ

Questions worth answering

Do I have to declare Airbnb income to Revenue in Ireland?
Yes - all income from Airbnb and similar platforms must be declared to Revenue, generally under Case IV as other income, regardless of how small the amount is.
Does rent-a-room relief cover Airbnb income?
Generally no. Rent-a-room relief, worth up to €14,000 a year, does not apply to income from guests booked through a platform for short stays under 28 days.
Should I use Form 11 or Form 12 for Airbnb income?
Use Form 12 in myAccount if your net non-PAYE income is under €5,000 and gross is under €30,000. Above either threshold, register for self-assessment and file Form 11 through ROS.
When is the deadline to declare Airbnb income in Ireland?
Returns and payment are due by 31 October the year after you earned the income. Filing and paying through ROS usually extends the deadline into mid-November.
What expenses can I deduct from Airbnb income?
Costs wholly and directly tied to the letting - cleaning, linen, platform service fees, and a fair share of utilities for the let period - are generally deductible against your Case IV income.
What happens if I don't declare Airbnb income?
Revenue receives payout data from platforms and matches it against filed returns. Undeclared income can lead to a tax assessment, interest, and a late filing surcharge.
Is Airbnb income taxed as rental income in Ireland?
Usually not. Because short-term bookings don't create a tenancy, this income is normally taxed under Case IV as other income rather than Case V rental income.
Do I need to register for VAT on Airbnb income?
Only if your total turnover from self-employed and letting activity crosses the VAT registration threshold for services - check your combined turnover against the current limit each year.
