AIO supplement

The co-resident rule and your AIO supplement

If you live on your own or with a partner, and there is no-one else living at your address, you will continue to receive an AIO supplement as usual. If there is another person aged 21 over living in your house, however, you may receive a lower AIO supplement.

The co-resident rule: how does it work?

We have always looked at your income and assets, but as from 1 January 2015, we will also take account of any other adults aged 21 or over living in your house because, if so, it is likely that they will contribute towards the household expenses. We refer to such people as co-residents. Your AIO supplement will be reduced for each co-resident living at your address.

  • What do we mean by "co-resident"?
    • Anyone except for a partner can be a co-resident, including your child, father or mother.
    • It makes no difference whether they actually contribute towards the household costs.
    • We only take your own income and, if applicable, your partner's income into account when calculating the amount of your AIO supplement. We do not take account of income received by co-residents.
  • When is a person not regarded as a co-resident?

    You do not have a co-resident if:

    • someone is living at your address but they are studying or training, and they qualify for a student grant or loan
    • you are in a 'commercial relationship'. This means that:
      - you rent a room from someone, or
      - you are a lodger, or
      - someone rents a room in your home, or
      - you have a lodger.
      If you have a commercial relationship with someone, you will have to provide proof in the form of a written agreement, as well as proof that rent has been paid. You cannot have a commercial relationship with your child, grandchild, father, mother, brother or sister. However, it is possible to have a commercial relationship with your cousin, niece or nephew, or your uncle or aunt.
  • Reductions to your AIO supplement under the co-resident rule

    The more people there are living at your address, the lower the AIO supplement you will receive. We calculate the reduction to your supplement as follows:

    (40% + number of co-residents x 30%) divided by number of co-residents x standard amount. The number of co-residents includes you and your partner, if applicable.

    You are a single person living at the same address as two other adults aged 21 or over who are co-residents. The standard amount applicable to you is (40% + 3 x 30%) = 130% divided by 3 = 43.33%.
    Your standard amount is therefore 43.33% x € 1,499.56 = € 649.76.
    The number 3 signifies one single person and 2 other persons who are co-residents living at your address.

NB If you live alone and you continue to live alone, nothing will change for you.
If you live with your partner and no-one else, and this situation stays the same, nothing will change for you.

Reporting a change

If someone starts living at your address, let us know without delay - even if that person is not yet registered with the municipal population register. We will then adjust your AIO supplement.
