# How do I add National Insurance numbers to employee details?

Within **Cintra iQ**, you can add **National Insurance** (NI) numbers to the following forms.

## Tax and NI form

Once an **HMRC** download occurs, and if the **National Insurance** code is missing for an existing employee, the **NI Number** field on the **National Insurance** tab will be automatically populated.

1. Navigate to the employee's **Tax & NI Details** form. Go to **Cintra iQ**: Employment Records > Forms > Tax and NI.
2. Navigate to the **National Insurance** tab.

## Personal Details form

Alternatively, you can record the **NI** **Number** via the employee's **Personal Details** form.

Go to **Cintra iQ**: Personnel Records > Forms > Personal Details.

## Amend Record Identifier form

You can also update the **NI** **Number** if it is part of a **Person Identifier** via the employee's **Amend Record Identifier** **Person** form.

1. Go to **Cintra iQ**: Personnel Records > Navigator.
2. Select the desired employee record.
3. Right-click: **Amend Record Identifier**.
4. Update the **Identifier** field.
