Making Tax Digital for Income Tax Self-Assessment (MTD for ITSA)

Summary

Making Tax Digital for Income Tax Self-Assessment (MTD for ITSA) represents a significant modernization of the UK’s tax system for sole traders and landlords. The core of the policy requires these individuals to maintain digital business records and use MTD-compatible software to provide quarterly updates on income and expenditure to HM Revenue & Customs (HMRC).
