Key Points to Know About MTD for CT


February 01, 2021

On 12 November 2020, HMRC launched a consultation document to analyse how the systems placed for Making Tax Digital (MTD) and already publicly in use for VAT could be implemented for Corporation Tax (CT). Many fundamental changes are being sought by HMRC so corporates must engage in the consultation either directly or through interested parties such as FTI Consulting.

Companies need to maintain their records digitally and submit quarterly updates as well as year-end tax return using MTD compatible software.

All the VAT-registered businesses with a taxable turnover above the VAT threshold is currently encompassed by the Making Tax Digital (MTD) regime which is launched in 2018 and from April 2022, it will be extended to all VAT-registered businesses below the threshold. 

For those who receive income from self-employment and/or property, MTD will be mandated for income tax for them from April 2023 and to cover the corporation tax, it is proposed that the regime will be expanded further. The companies will be able to participate in a voluntary pilot in 2024 as suggested by the current timelines.
