Last updated: 8 February 2026

1. About SimpleCompanyTax

SimpleCompanyTax (“we”, “us”, “our”) is a UK-based software platform operated by Infuzest Ltd (company registered in England and Wales), trading as SimpleCompanyTax. Our service allows eligible users to prepare Corporation Tax returns (CT600) and statutory accounts in iXBRL format for submission to HM Revenue & Customs (HMRC) and Companies House.

2. Scope of the service

SimpleCompanyTax is designed only for:

  • UK single-entity limited companies
  • Dormant companies
  • Micro-entities under FRS 105 (any profit level — full 3-band Corporation Tax with marginal relief)
  • Small companies under FRS 102 Section 1A
  • Standard 12-month accounting periods
  • Companies with no associated companies

The service does not currently support:

  • Companies with associated companies (coming soon)
  • Short accounting periods (coming soon)
  • Group companies or consolidated accounts
  • R&D tax relief claims
  • Transfer pricing
  • Overseas permanent establishments
  • Bespoke or complex tax advice

By using the service, you confirm that your company falls within the supported scope.

3. Not a substitute for professional advice

SimpleCompanyTax provides software tools, not accounting or tax advice. You are responsible for: the accuracy and completeness of all data entered; determining whether the service is suitable for your circumstances; seeking professional advice where your situation is complex. We do not provide personalised tax advice.

4. HMRC & Companies House submissions

SimpleCompanyTax submits CT600 returns to HMRC via the Government Gateway Transaction Engine and files statutory accounts with Companies House via the Companies House API. An IRmark receipt is returned and stored for every successful HMRC submission. Acceptance of any filing ultimately depends on statutory and technical checks performed by HMRC and Companies House and is not guaranteed by SimpleCompanyTax.

5. User responsibilities

You agree to: provide accurate and truthful information; use the platform only for companies you are authorised to act for; review all generated documents before submission; comply with all applicable UK laws and filing obligations.

6. Pricing & payments

Pricing is stated per company, per year. Fees are non-refundable once filing preparation has commenced, unless required by law. We may update pricing with reasonable notice.

7. Intellectual property

All software, content, and branding on SimpleCompanyTax remain our intellectual property. You retain full ownership of: your company data; generated CT600 XML files; generated iXBRL accounts.

8. Data & security

We take reasonable technical and organisational measures to protect your data. For details, see our Privacy Policy.

9. Limitation of liability

To the maximum extent permitted by law: we are not liable for indirect or consequential losses; our liability is limited to the fees paid for the relevant service period. Nothing in these terms limits liability for fraud or matters that cannot be excluded by law.

10. Termination

We may suspend or terminate access if: these terms are breached; the service is used outside its intended scope; required by law or regulatory action.

11. Governing law

These terms are governed by the laws of England and Wales, and courts of England and Wales shall have exclusive jurisdiction.
