Please do not run the Tax Code Uplift Tool until you have had your account updated to the newest version  - you will receive notification of this update.



Prior to starting a payrun with a pay date in the new tax year you must complete the following:

  • Ensuring Tax and Accounting Periods are setup for the new tax year
  • Uplift Employees Tax Codes and apply any P9 notifications

As long as you have completed all pay runs in the previous tax year you can prepare the new tax year prior to completing the UK End of Year Guide

Setup Tax and Accounting Periods

To setup the NetSuite accounting periods and tax periods for the new tax period review the Setting Up New Tax Year instructions.



For the 24/25 Tax year the new default tax code remains the same as TYE 2023/2024 1257L as there is no uplift to the personal allowance.

The uplift is therefore as follows:

Tax CodeUplift
Ladd 0
Madd 0
Nadd 0



Tax Code Uplift

To simplify the uplift process ICS provides a user interface to allow employees to be updated in bulk. The tool displays a list of employees, auto selecting those eligible for uplift.

If you have configured HMRC DPS, any P9 Notifications for employees will now be picked up by the Tax Code Uplift Tool.

Once you have run this process you will need to check these to ensure all have been picked up correctly. If you have not got the HMRC DPS configured please follow these instructions to do this prior to running this process. 


The uplift logic works by comparing the tax code from the last payslip (linked on the employee) from the prior tax year, and the tax code on the employee record. The uplift will automatically check the employee for update if:

  • W1/M1 is set - it will be cleared for the new tax year
  • If the tax code from the prior payslip is eligible for uplift and applying uplift to the tax code is different to the employee record tax code
  • If there is a P9 Notification received in the DPS for the employee

Running Tax Code Uplift Tool

  1. Navigate to Payroll Administration > UK Reports > RTI Manager
  2. Select the Subsidiary you need to run the uplift on and the tax year ending in question.
  3. Click "Tax Code Uplift"
  4. On the uplift page you will see that the system will automatically assign whether or not someone needs an uplift or a W1/M1 flag removed and only tick those to be uplifted. The page will show you their current tax code, the last tax code used, if there is a coding notice that overrides uplift, the message (the action that is occurring) and what the tax code will be.

  5. You can override this if you believe necessary by entering a tick in the checkbox for "Update?" next to the employee and entering a tax code into the "Update Tax Code" field.


  6. Click "Update"


You should run a secondary check in the DPS to ensure that the most recent P9 notification was the one that was picked up - this will only effect employees who have had multiple P9 notifications.

To do this you will need to navigate to Payroll Administration > United Kingdom > HMRC DPS Notifications
Enter a tick in Include Recently Updated? 
Check that the notice that was applied was the one with the most recent Issued Date. 
Ignore those that are not the most recent and apply those that are.
