Since the introduction of the Structures and Buildings Allowances (SBA) from 29 October 2018, taxpayers and advisers have been waiting for HMRC’s guidance to better understand how the legislation will be interpreted in practice. HMRC’s latest guidance is a good start, but a number of questions remain (HMRC have stated that further updates to the Capital Allowances Manual will follow). Businesses should be considering whether their current processes are sufficient to capture the information required to substantiate a claim, so they can benefit from this new tax relief.
