Last updated

If you initially applied for SEIS/EIS advance assurance (AA) with a specific fundraising target and later decide to raise a different amount, you may wonder whether this impacts your ability to raise funds under SEIS/EIS. Here’s what startup founders need to know.

Key considerations when increasing your raise

1. Advance Assurance is not a statutory requirement

2. SEIS/EIS limits still apply

3. HMRC vs investor perspective

4. Compliance still matters

What should you do if your raise changes?
