HMRC Tax Valuation (Form VAL231 & Post-Transaction Rulings)
Independent share valuations for UK tax purposes - EMI VAL231 submissions, post-transaction rulings, employment-related securities and share-for-share exchanges.
What is an HMRC tax valuation?
A wide range of UK tax events depend on the open-market value of unquoted shares: granting EMI options, making Section 431 elections, transferring shares between connected parties, restructuring share capital, exchanging shares in a corporate reorganisation, and seeking HMRC's view on a completed transaction.
Where HMRC is or may become involved - through formal submission, post-transaction ruling or future enquiry - an independent, well-evidenced valuation is the foundation of the position taken in the tax return or election.
Optival prepares HMRC-aware valuations across the full range of UK tax scenarios, with reports written in a format and tone consistent with HMRC's Shares & Assets Valuation team's expectations.
When is it required?
EMI VAL231 advance agreement
Independent valuation supporting the company's submission to HMRC for advance agreement of UMV and AMV before granting EMI options.
Post-transaction valuation rulings
Where a transaction has completed and certainty over the tax treatment is required, an independent valuation supports the application to HMRC.
Share-for-share exchanges & reorganisations
Schemes of arrangement, group reorganisations and demergers requiring evidenced share values for stamp duty, CGT and corporation tax purposes.
Employment-related securities (ERS)
Acquisitions and disposals of shares by employees or directors triggering ERS reporting obligations.
Our methodology
Tax valuations apply the standard 'hypothetical purchaser and vendor' test (section 272 TCGA 1992 for CGT; section 160 IHTA 1984 for IHT) - the price the asset would fetch if sold on the open market between informed but otherwise unconnected parties.
Earnings multiples
For trading companies, calibrated to listed comparables, sector indices and recent UK private transaction evidence with adjustments for size, growth, margin and risk profile.
Net asset value
For investment companies, property holding vehicles or asset-rich businesses, anchored on adjusted balance sheet with assets restated to fair value.
Discounted cash flow
Where reliable forecasts exist, used as a primary or cross-check methodology with sensitivities on growth, margin and discount rate.
Discounts and waterfall analysis
Discounts for lack of control and lack of marketability calibrated to UK and US restricted-stock evidence; waterfall analysis where the cap table includes preference shares, convertibles or ratchets.
Key UK considerations
- HMRC's Shares & Assets Valuation team scrutinises the methodology, the comparables and the discounts applied - unsupported assertions are routinely challenged.
- Information available to the hypothetical purchaser is restricted to that which would reasonably be available; post-event hindsight cannot be used.
- Different tax purposes use different valuation bases: EMI uses UMV / AMV; CGT uses 'market value' under section 272 TCGA; IHT uses 'open-market value' under section 160 IHTA.
- Advance agreement (VAL231) is generally valid for 90 days from HMRC's response and lapses on a significant event.
- Post-transaction rulings can take several weeks to months to obtain - submissions should be made in a complete and well-evidenced form to minimise delay.
