Mida OS

EIS · Compliance

Submit your EIS compliance statement the right way.

The EIS1 compliance statement is the formal filing that unlocks your investors’ tax relief. HMRC scrutinises every detail. Mida OS prepares and submits it with complete accuracy.

We compile your raise details, verify every investor against your cap table, and submit the EIS1 statement to HMRC. Once approved, we issue EIS3 certificates to each investor directly.

One managed stack for your startup’s back office.

Mida OS handles legal, accounting, compliance and payroll for UK founders — one price, everything included. £350/month.
