## Overview

In the **Settings** workspace, you maintain the retention period of the change log of **Tax Administration**.

## Navigation

The **Settings** workspace can be found in the **Administration** folder of the **Tax Administration** module and opens in **Edit** mode.

## Change Log

The **Change log** section controls how long historical entries are retained.

The **Hold-back time of history data in days** is the number of days after which change log entries become eligible for deletion. If you enter **10**, for example, change log entries are deleted after 10 days. Set the value to **`-1`** to keep change log history indefinitely (default).

## Editing the Retention Period

To change the retention period, proceed as follows:

1. Enter the desired retention period in **Hold-back time of history data in days**, or enter **`-1`** to keep history indefinitely.

2. Click **Save** to store the new value.

3. To purge change-log entries that are now older than the configured retention period, click **Apply retention period**.

> **Warning:** **Apply retention period** permanently deletes change-log entries older than the configured retention period across every workspace that maintains a change log (Roles, Role allocation, Certificates, Units, Organisational structures, and any other workspace with a **Change log** button). The action cannot be undone.

> **Note:** Use a value of **`-1`** when audit or compliance requirements mandate that the change log must be kept indefinitely.
