Budget: why the government should reform business rates

Author: ICAEW Insights

Published: 12 Nov 2025

The Chancellor should use this month’s Budget to push ahead with planned reforms of the “poorly designed” business rates system, says ICAEW.

ICAEW has proposed practical measures for business rates reform, such as a rates break and a rates-free period, to provide short-term improvements to the system and make it more business-friendly, as the Chancellor prepares her Budget for 26 November.

Business rates can almost act as a tax on the expansion of premises and productivity investment when faced with the prospect of a rates increase. ICAEW has said repeatedly that the tax is a “major obstacle” to delivering a level playing field for businesses. A survey of 500 members has found that 62% would favour replacing the current business rates system with one that rewards investment and green upgrades as a means to achieving business growth in the UK.

Business rates continue to hold back growth, despite several reviews of the tax and a commitment from the government to replace the system.

In its pre-Budget submission to HM Treasury, ICAEW outlined four ways the government could get reform going with small changes ahead of any substantive changes:

  • A rates break on a new property when a business moves premises. This would reduce costs associated with needing to retain two premises during transition, which would remove one disincentive for businesses to expand.
  • Rates-free periods or reductions to help a business increase in size, to prevent a lag between taking on increased costs and generating incremental revenue.
  • Increased limits under which properties can qualify for small rates relief, so more small properties are in scope.
  • Reducing by half the percentages by which rate liabilities can increase year-on-year under transitional relief.

These measures would support growth while preserving the £29bn in revenues that business rates raises.

“The business rates system is poorly designed and creates a major obstacle to delivering a level playing field for businesses,” said Frank Haskew, ICAEW Head of Taxation Policy.

Bold action now, such as the tax break for businesses moving to a new property, would be a shot in the arm for the UK high street, he added.

“While business rates remain an important source of revenue for local authorities, the system must be evolved to support a modern, dynamic economy that provides a more stable platform for businesses and for both central and local government.”
