Employment Related Securities Expert Witness UK

Employment Related Securities (ERS) disputes under ITEPA 2003 arise where HMRC challenges the valuation placed on shares or options at grant, vesting, or exercise. These disputes are particularly common in growth share arrangements, hurdle structures, restricted share plans, and EMI option schemes where the difference between the taxpayer's valuation and HMRC's assessment can be substantial.

A tax expert witness provides independent analysis of the correct valuation at the relevant date, assessing whether HMRC's valuation methodology is appropriate and whether the correct tax treatment has been applied. Disputes frequently involve complex questions about commercial restrictions on shares, market value at acquisition, and the interaction between income tax and capital gains tax on disposal.

s431 elections under ITEPA 2003 allow employees to elect to be taxed on the unrestricted market value of shares at acquisition rather than when restrictions lift. Disputes arise where HMRC challenges the value used in the election or the tax treatment of the overall arrangement, requiring expert evidence on both valuation and technical tax analysis.
