SEIS and EIS loss relief: what company status can tell you

A practical, evidence-first explanation of loss signals, negligible value claims and the records to assemble before taking tax advice.

General information only. This is not financial, investment, tax or legal advice. Check the linked official guidance and use a qualified adviser for a claim or decision.

A status signal is the start, not the claim

A dissolved, liquidation or administration status can justify a closer review, but it does not by itself establish the amount or timing of a tax loss. The investor, share issue, relief history and disposal or deemed disposal still matter.

HMRC's EIS overview explains that a qualifying loss may be set against income after deducting Income Tax relief already given. SEIS and EIS have detailed conditions, so use the public record to assemble evidence rather than to calculate a filing position automatically.

Negligible value claims

Where shares are still owned but have become worth almost nothing, HMRC may accept a negligible value claim. The official guidance says the asset must have become negligible while owned; it cannot already have been negligible on acquisition.

A share-loss-relief claim that depends on a deemed disposal also needs the underlying negligible-value claim. Timing can matter, especially if a company has ceased to exist.
