If HMRC send you an electronic notice to change an employee's tax code, you can apply this in your software.

HMRC may issue an effective from date with a tax code notification. If you receive a notice with a date in the IR secure mailbox, your software applies the effective from date automatically.

Your software applies the new tax code when your process date is on or after this date.
