Construction industry scheme (CIS) 

HMRC has used the latest edition of its Agent Update publication to remind agents that the CIS nil filing requirement, and the full CIS late filing penalty regime, will be restored from April 2026. Separately, HMRC is writing to businesses in the construction sector to let them know about measures applying from April 2026 to help tackle tax fraud in labour supply chains.
