If an employee’s tax code, National Insurance category, or other PAYE details change (for example after an HMRC notice), update their **Tax Details** in Zoho Payroll.

1.  Go to **Employees**.
2.  Open the employee.
3.  On **Overview**, click the edit icon in **Tax Details**.
4.  Update the fields you need, such as **Tax Code**, **National Insurance Number**, **National Insurance Category**, **Director’s National Insurance**, or **Starter Declaration**.
5.  Click **Save**.

Refer to the [GOV.UK guidance on National Insurance category letters](https://www.gov.uk/national-insurance-rates-letters/category-letters) when you choose a category, and to [Director’s National Insurance](/uk/payroll/help/employer/employees/add-employees.html#directors-national-insurance) for **Annual Pro Rata** and **Alternative**.

**Note:** These changes apply to upcoming pay runs. They do not change a pay run that is already in draft or approved.

For the full tax fields when you add an employee, refer to [Add Employees - Tax Details](/uk/payroll/help/employer/employees/add-employees.html#tax-details).
