# MCR: How do I know errors are in the submitted return?

## How do I know errors are in the submitted return?

You will be notified of any errors under the **Download** section of the **Employer's Portal** within the **Teachers' Pensions** website.

[https://www.teacherspensions.co.uk/employers/employer-hub.aspx](https://www.teacherspensions.co.uk/employers/employer-hub.aspx)

It is best practise to fill in as much information within **Cintra iQ** so that the occurrence of errors are minimal. Prior to sending the file, review and address any errors in the **Data Issues** tab of the **Teachers Pension - Monthly Contributions Reconciliation** window within **Cintra iQ**. The data file must be sent every month to **Teachers' Pensions** no matter if your payrolls are weekly or monthly.
