Who it suits
Homeowners or tenants with a furnished room in their only or main home, who are comfortable sharing their home and managing a lodger or tenant. The UK scheme can cover a furnished room let to a lodger; Irish relief is for qualifying residential arrangements.
People pay for a place to live, and a furnished room in your home may suit someone looking for a home there. A resident lodger can provide regular rent, but you share your home and take on practical responsibilities.
Step by step
- Check that this is your main home. For the UK scheme, check that the room is furnished and that your circumstances meet the conditions. Irish relief depends on the home being a qualifying residence. Read the official conditions before counting on tax relief. GOV.UK Revenue About 30-60 minutes.
- Choose a resident lodger or short-term guests. Decide whether you want someone living in your home or guests staying briefly. The distinction matters: Irish Rent-a-Room Relief is for qualifying residential arrangements and generally does not cover short-term guests. Citizens Information About 30 minutes.
- Compare similar local room prices. Look at rooms in your area with similar facilities and access to shared spaces. Compare what is included, such as bills or household services, and choose a price you can explain clearly. About 1-2 hours.
- Decide what the rent includes. List which shared rooms the lodger can use, what furnishings are provided and whether household services are included. Keep a record of rent and any other payments you receive. About 30-60 minutes.
- Prepare a safe, usable room. Check that the room is ready, furnishings are in good condition and the property is safe. UK guidance says keeping the property safe and in good repair is the resident landlord’s responsibility. GOV.UK About Half a day to several days.
- Choose where to find a lodger. You can ask your own contacts or advertise locally, then agree the arrangement directly. Short-term rental apps may suit a different type of letting; occasional short-term UK rentals may need to be reported to HMRC. Check how your planned arrangement is treated for tax. GOV.UK About 1-2 hours to choose; finding someone may take longer.
- Speak with applicants and check references. Explain the house arrangements and ask potential lodgers for references. Follow up the references before signing an agreement. GOV.UK About Allow 30-60 minutes per applicant.
- Put the agreement in writing. Write down the rent, what it includes and the practical household arrangements before the person moves in. If you are unsure about the agreement or your responsibilities, check with a housing advice service or a qualified adviser. About 1-2 hours.
- Record gross income and payments. Keep a dated record of rent and other payments before expenses. In the UK, the Rent a Room limit is £7,500 a year, or £3,750 if someone else receives income from letting accommodation in the same property. GOV.UK About 10-15 minutes each time you receive money.
- Check the tax treatment each year. Check the rules for your country and whether your arrangement qualifies. In Ireland, if gross rental income exceeds €14,000, the total income is taxable rather than only the amount above the limit. Revenue About 30-60 minutes each tax year.
Your first 15 minutes
Check whether your room and type of letting qualify for the relevant relief, then write a clear description of the room and the household arrangements.
The money
Compare rooms nearby with similar size, facilities and access to shared spaces. Decide whether bills and services are included, and make the amount and any extra payments clear in writing; tax-relief limits are not typical room prices.
Example only: If you charge £550 for one month and spend £80 on extra household costs, £550 − £80 = £470 before tax. If you charge €900 and spend €120, €900 − €120 = €780 before tax. These are invented figures, not typical rents; compare gross annual income with the relevant relief rules.

The rules
You may be able to rent a room in the UK or Ireland. Tax relief depends on your home and how you let the room. Check the tax conditions and any housing rules before you agree to let.
