15 common SMS reporting mistakes sponsors make

The UK’s sponsorship system places a significant portion of the compliance responsibilities on the employer that holds a sponsor licence.

One of the most important elements of this framework is the Sponsor Management System (SMS), which organisations must use to report changes affecting both sponsored workers and the business itself.

According to official guidance from the UK Home Office, sponsors must meet strict reporting deadlines and maintain accurate records.

Failure to do so can lead to licence suspension or revocation, along with compliance visits by UK Immigration authorities.

In this article, we outline 15 common SMS reporting mistakes that often place sponsors at risk of scrutiny from UKVI.

Why SMS reporting matters

Under the sponsor guidance for workers and temporary workers, sponsor licence holders must report certain changes within specific time limits. In most cases, changes affecting a sponsored worker must be reported within 10 working days, while changes to the organisation must generally be reported within 20 working days.

These reporting duties are part of wider sponsor responsibilities such as record-keeping, monitoring immigration compliance, and cooperating with the Home Office.

If these duties are breached, the Home Office may downgrade, suspend, or revoke a licence, and may carry out compliance inspections to assess whether the sponsor is meeting its obligations.

Note: In practice, many compliance visits are triggered not by intentional misconduct but by simple reporting errors or delays.

15 common SMS reporting errors

1. Missing the 10-day reporting deadline

One of the most frequent compliance issues is failure to report worker-related changes within the required 10-day timeframe.

2. Not reporting when a sponsored worker fails to start work

If a sponsored employee does not start their role as expected, sponsors must report this via SMS and include any known reason for the non-attendance.

3. Ignoring prolonged unauthorised absences

Sponsors must report when a sponsored worker is absent without permission for more than 10 consecutive working days. Failure to do so may indicate weak monitoring systems.

4. Failing to report early termination of employment

If a sponsored worker resigns, is dismissed, or their contract ends earlier than stated on their Certificate of Sponsorship (CoS), the change must be reported promptly.

5. Not reporting when sponsorship ends

Sponsors must inform the Home Office if they stop sponsoring a worker, even if the worker switches to another immigration category.

6. Overlooking changes to job role or duties

Significant changes to the worker’s role, such as a new job title or a major change in responsibilities, must be reported because they may affect visa eligibility.

7. Failing to report changes to salary or working hours

If pay or hours change in a way that could affect sponsorship conditions, this should be reported through SMS within the relevant timeframe.

8. Not updating work location changes

The Home Office requires sponsors to report changes to a worker’s main work location or new client sites where applicable.

9. Not reporting permanent remote working arrangements

If a sponsored worker switches to permanent or long-term remote working role, with little or no physical office attendance, sponsors must notify the Home Office through SMS.

10. Failing to report suspected breaches of visa conditions

Sponsors are expected to inform the Home Office as soon as reasonably possible when and if they suspect a sponsored worker has breached the conditions of their visa.

11. Not updating organisational details

Changes such as a new company name, address, or branch must be updated through the SMS system to ensure the sponsor licence remains up-to-date and accurate.

12. Forgetting to report changes to key personnel

Sponsors must provide updates through SMS if there are changes to roles such as the Authorising Officer, Key Contact, or Level 1 users responsible for the sponsor licence.

13. Failing to report structural changes in the business

Mergers, acquisitions, or the creation of new linked entities must be reported because they can affect sponsorship responsibilities.

14. Submitting inaccurate or incomplete SMS reports

Providing incorrect information or failing to align SMS entries with HR records may raise compliance concerns during audits.

15. Poor internal systems for identifying reportable events

The Home Office expects sponsors to have processes in place to track worker attendance, employment changes, and compliance issues so they can report them promptly.

Conclusion

SMS reporting is at the heart of the UK sponsorship compliance framework. Many compliance visits arise simply due to sponsors failing to report changes quickly or accurately, rather than due to deliberate breaches of immigration rules.

By understanding the Home Office’s reporting expectations and ensuring robust internal systems, employers can significantly reduce the risk of enforcement action.
