How EIS share loss is calculated

HMRC requires EIS Income Tax relief obtained and retained to be deducted from the loss. A qualifying allowable loss may be claimed against income in the disposal year or preceding year, or used against gains, but cannot be used twice. Check the disposal, qualifying-company and claim conditions separately.
