Social investment tax relief section (SA100)

This section is used to enter investments for which Social Investment Tax Relief (SITR) can be claimed.

Social Investment Tax Relief can be claimed on the purchase of qualifying shares or investments in:

  • a social enterprise such as a community interest company

  • a community benefit society

  • a charity

SITR cannot be claimed if another relief has already been claimed for the investment, such as:

  • Enterprise Investment Scheme

  • Seed Enterprise Investment Scheme

  • Community Investment Tax Relief Scheme

Relief is available at 30% of the amount invested, up to a maximum annual investment of £1,000,000.

Refer to the HMRC Tax return for Self Assessment guidance if needed (opens in a new tab).

  1. From the Clients menu, select Clients list.
  2. Change the client list view to either Active clients or a custom view that includes all relevant clients.

    3. If any of the entries are greyed out and you cannot select them, this is a restricted item — the parent client record has been set to Private and you do not have access. If you believe this is a mistake, contact your IRIS Elements administrator. Users who have Administrator level permissions are able to view all public and private client records, even those where they are not named as assigned users.

  3. Open the relevant client record.
  4. On the Personal tax returns widget on the client dashboard, select the required return. The Status tab is shown by default.
