The set of monetary income regularly received by the household and its members who earn individual income, regardless of its source, once deductions for Social Security contributions and other similar payments (Social Welfare Entities, Mandatory Mutualities, and Pension Rights) have been made, as well as the amounts paid in taxes.

In the case of salaried work, only the withholdings for the Personal Income Tax (IRPF) should be taken into consideration, whereas in the case of self-employment, both the withholdings and the fractional payments of the IRPF should be taken into account.

It is considered that household members receive income when they are working or have a job for which they receive remuneration, or receive some pension, subsidies, capital rents, or transfers.

Monthly income refers to the regular income received in the last calendar month, taking into account the prorating of extraordinary income and other income that is received periodically, even if not monthly.
