From www.accountingweb.co.uk: (UK context) HMRC’s consultation paper discusses the potential for pre-populating tax returns using third-party data to alleviate administrative burdens and improve accuracy for taxpayers.

The proposal includes enhanced reporting obligations for financial institutions and a robust taxpayer identification system to ensure accurate data linking.

Additionally, the consultation explores expanding the type of data collected, such as dividends and other investment income, while emphasizing the need for a unified system to integrate tax information effectively.
