Improved UK Tax Declaration Flow for New Employees

You can now onboard new UK employees with a simpler tax declaration flow that’s aligned with HMRC’s recommended new starter process.
Instead of asking employees for details they might not know, we guide them through two clear options:
Enter details from their P45 (if they have one), or
Complete the HMRC new starter declaration flow.
This makes it easier to capture the right tax information, especially for employees starting their first job or working for multiple employers.
Additional improvements
Tax code history:
 You can now save multiple tax codes per employee to track history and support retrospective payroll calculations (only one tax code can be active at a time).
New ESS permission: 
You can now allow employees to use ESS without being able to change their tax details, keeping tax updates with payroll/admin users.
