An accrual method of accounting records income and expenses when they are earned or incurred, not when cash is actually received or paid. In legal practice it underpins financial statements used in company law, commercial contracts, insolvency, tax, banking, and litigation involving loss or valuation.Across the UK and Ireland, accruals accounting is required for most companies under company law and accounting standards (for example, UK-adopted IFRS or FRS 102 in the UK, and corresponding standards in Ireland), and is the default basis for statutory accounts filed with Companies House or the Companies Registration Office.In tax law, the concept is reflected in provisions requiring trading profits to be calculated on an “earnings basis” or in accordance with “generally accepted accounting practice” (GAAP), subject to specific tax adjustments. The term itself is not generally exhaustively defined in primary legislation, but is embedded through references to GAAP and accounting standards and is explained in HMRC and Irish Revenue guidance.Usage and meaning are broadly consistent across England and Wales, Scotland, Northern Ireland and Ireland, making the accrual method the standard benchmark for assessing profit, loss and solvency in most legal and transactional contexts.
