What this resource covers

United Kingdom tax and compliance toolkit turns official guidance and ecosystem practice into an action plan for UK founders working through Companies House, HMRC, ICO, SEIS/EIS and national growth support. Use it to decide what to do next, what evidence to save and which official source to verify before acting.

This guide is written for UK founders working through Companies House, HMRC, ICO, SEIS/EIS and national growth support. It is practical guidance, not legal, tax, investment or regulated professional advice.

Action checklist

  1. Create a monthly tax and record-keeping calendar.
  2. Define who owns invoicing, payroll, filings and bookkeeping.
  3. Reconcile every filing task with the official tax authority source.
