Current monthly income describes the amount an individual is presently receiving per calendar month from all sources, used in affordability assessments, maintenance, insolvency contributions and means testing. It is not generally a defined statutory term in the UK or Ireland; it is a descriptive budgeting measure, with figures taken gross (before tax) or net (after tax) depending on the relevant regime or form.Typical inclusions are salary, overtime, bonuses, commission, self-employment profit or drawings, pension, rental income, dividends, state benefits and tax credits, and maintenance received. Where income fluctuates, practitioners commonly average over 3–12 months (or one accounting year for the self-employed). Evidence usually includes recent payslips, bank statements, tax returns, accounts, and award letters.In England & Wales and Northern Ireland, bankruptcy income payment agreements/orders and other insolvency solutions assess monthly surplus income; Scotland uses the Common Financial Tool to set Debtor Contribution Orders; Ireland assesses net disposable income monthly using Reasonable Living Expenses under the personal insolvency and bankruptcy frameworks.In family cases, spousal maintenance and financial remedies use monthly schedules; statutory child maintenance is set on gross weekly income, often converted for budgeting. Across England & Wales, Scotland, Northern Ireland and Ireland, usage is broadly consistent as a practical, source-inclusive, monthly income measure.
