ICAEW REP 77/21: Basis Period Reform

Pushing through proposals to change basis periods ahead of the expansion of Making Tax Digital will cause as many problems as it solves and would be a backwards step for affected businesses, warns ICAEW in its response to HMRC's consultation on aligning basis periods with the tax year. ICAEW has urged the government not to implement to proposals.

ICAEW REP 66/21 Timely payment

In responding to HMRC's call for evidence on timely payment, ICAEW argues that earlier payment of income and corporation tax should not be considered until the economy has recovered and that earlier payment should not be based on in-year estimates without HMRC first demonstrating that they can be a reliable basis for earlier payment.
