Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment she has made of the potential impact of reducing the writing-down allowance main rate in corporation tax on women-led businesses.

Since the introduction of full expensing, most businesses now claim first-year allowances, such as full expensing and the Annual Investment Allowance (AIA), to claim relief on their investments, with 99% of businesses investing under the AIA’s £1 million threshold. The government has maintained these key reliefs, as well as the low Corporation Tax main rate of 25%.

At Budget, the government announced that it is decreasing the main rate of writing-down allowance by 4ppt to 14% from April 2026. This change allows us to fully fund a new 40% first-year allowance (FYA) while also raising revenue to protect the public finances. This new FYA will allow businesses to deduct much of the cost of their investment in the year they make that investment and lower their tax bill. It will be available for assets bought for leasing and for unincorporated businesses, which do not benefit from full expensing, and broadly preserves the current incentives to invest.

For future investment, the present value and cost of capital for businesses that claim the new first-year allowance remains broadly the same. The expected impacts of this measure, included the equalities impacts, are set out on gov.uk. There are no disproportionate impacts expected on women-led businesses or other protected groups as a result of this measure:
