OT44250 - Non-residents working on the UK continental shelf: self assessment and appeals: discovery assessments and appeals

Discovery

HMRC may make a discovery assessment to make good a loss of tax where it is discovered that:

• an amount which ought to have been assessed to tax has not been assessed, or
• an assessment to tax is or has become insufficient

provided a company tax return has been delivered where there has been fraudulent or negligent conduct on the part of the company or a person acting on the company’s behalf (see FA98\Sch18\paras41 & 43).

Appeals

An appeal may be brought against a discovery assessment provided it is made in writing and sent to HMRC within 30 days after the notice of assessment is issued - FA1998\Sch18\para 48.

From 1st April 2009 the Tribunal procedure will apply. A review may be requested and an appeal should be made to the First Tier Tribunal.
