Not knowing whether the company still qualifies before approaching investors
SEIS requires the company to have <a href="https://www.gov.uk/guidance/venture-capital-schemes-apply-to-use-the-seed-enterprise-investment-scheme">gross assets no more than £350,000, fewer than 25 FTE, and to have started trading within the three years before the share issue</a>. EIS has different thresholds and restricts the use of raised funds to qualifying purposes. A company that has grown its gross assets, taken on staff, or passed the trading-age test may no longer qualify, and applying incorrectly wastes investor confidence.
