If your spouse, civil partner or cohabitant is dependent on you or is on a low income, you may be able to claim an increase in your payment for them. This increase is called an Increase for a Qualified Adult (IQA). If they are earning €100 or less you will get the maximum IQA. If they are earning between €100 and €310 you will get a reduced rate of IQA. If they are earning more than €310, you will not get an IQA.
