ATCS05620 - Advance Tax Certainty Service: Process: Post-issuance: Changes to facts
An applicant's ability to rely on a clearance may be impacted where either:
- there has been a material change to the facts of an investment project from how it is set out in the clearance
- anything set out in the clearance, and which is material to it, such as a critical assumption, is no longer accurate
If the customer is unsure whether a change is considered material, they should contact HMRC for advice. Failure to notify HMRC may mean the clearance is no longer valid, cannot be relied upon or may incur a penalty.
