SEIS/EIS Advice in Portsmouth

Q: Can a Portsmouth startup lose its SEIS/EIS status?

Yes. Breaching qualifying conditions — such as using funds for non-qualifying purposes, exceeding the gross assets limit, or conducting a non-qualifying trade — can trigger loss of status and clawback of investor tax relief. For defence tech, autonomous systems, and naval innovation startups ventures in Portsmouth, common risks include inadvertent non-qualifying activities and share-structure changes. The specialists in our network build ongoing compliance monitoring into their service.
