Changes to the provisional tax safe harbour rules

From 1 April, the requirement to pay provisional tax instalments in full and on time will be removed for customers using the safe harbour option. Use of money interest (UOMI) will only be charged if an amount remains unpaid after the end of year tax due date. 

The change will be effective for the 2023 year onwards. 

All other existing qualifications will remain, and late payment penalties will still apply. 

Billing such as reminder notices and alerts in myIR will still occur based on the information we hold.
