Quick Answer
Digital tools for recording financial transactions and managing business accounts.
Definition of Accounting Software
Accounting software is computer-based applications that help businesses and self-employed individuals record financial transactions, track income and expenses, generate invoices, and prepare for tax returns. With Making Tax Digital (MTD) requirements, HMRC-compatible software has become essential for many businesses.
Popular UK accounting software includes Xero, QuickBooks, FreeAgent, Sage, and Wave. These tools can connect to bank accounts for automatic transaction imports, generate financial reports, calculate VAT returns, and submit directly to HMRC where authorised.
Since April 2022, VAT-registered businesses must use MTD-compatible software to keep digital records and submit VAT returns. MTD for Income Tax Self Assessment will be mandatory from April 2026 for self-employed individuals and landlords with income over £50,000.
