Terms of Service

Last updated: July 2026

1. Introduction

These Terms of Service ("Terms") govern your use of the Taxpipe CT600 corporation tax return filing service ("Service") operated at taxpipe.co.uk.

These Terms are between Taxpipe and the company on whose behalf the Service is used ("you"). If you accept these Terms and use the Service as an individual acting for a company, you confirm that you are authorised to enter into these Terms on that company's behalf and to bind it. By using the Service, you agree to be bound by these Terms.

Taxpipe is a trading name. References to "we", "us", or "our" refer to Taxpipe.

2. Service Description

Taxpipe provides an online service for filing CT600 corporation tax returns to HMRC on behalf of UK limited companies. The Service includes data entry, automatic tax computation, iXBRL accounts generation, and electronic submission to HMRC.

2a. What the Service does and does not include

The Service files your Company Tax Return (form CT600), together with the Corporation Tax computations and iXBRL company accounts that accompany it, to HM Revenue & Customs (HMRC).

The Service does not file anything with Companies House. In particular, filing your company's annual accounts and confirmation statement with Companies House is a separate statutory obligation that remains your responsibility. Those filings have their own deadlines (for most companies, earlier than the Corporation Tax deadline). Taxpipe does not prepare, submit, monitor, or give any advice or reminders about them, and does not check, and is not responsible for, any Companies House deadline. You are solely responsible for meeting all Companies House deadlines and for any penalties, interest, or other consequences of failing to do so.

3. User Obligations

You are responsible for the accuracy and completeness of all information you provide through the Service, including company details, financial data, and Government Gateway credentials. You must have the authority to file tax returns for the company on whose behalf you are using the Service.

3a. Business use

You warrant that you use the Service in the course of your business, trade, or profession, and that you enter into these Terms as agent for and on behalf of a company, and not as a consumer. This warranty does not affect any rights you have that cannot be excluded or limited by law.

4. Payments and Refunds

Payment for the Service is processed securely by Stripe. All fees are displayed before you confirm your filing.

You are entitled to a full refund in the following circumstances:

  • Your CT600 return has not yet been accepted by HMRC at the time of your refund request.
  • HMRC rejects your return due to a software error caused by Taxpipe (not errors in the data you provided).

Refund requests must be made within 30 days of payment. To request a refund, email info@taxpipe.co.uk with your company name and the email address associated with your account. Refunds are issued to the original payment method within 5 to 10 business days.

4a. Money-Back Guarantee

We stand behind the quality of our service with a money-back guarantee. If you are not satisfied with the Service, you may request a full refund of the fee you paid within 30 days of payment, provided your CT600 return has not already been submitted to, and accepted by, HMRC. Once HMRC has accepted your return the filing is complete and this guarantee no longer applies.

If HMRC rejected your return due to a software error caused by Taxpipe (rather than errors in the information you provided), you are entitled to a full refund regardless of submission status. This guarantee is in addition to your legal rights and to the refund rights set out in Section 4 above.

5. Intellectual Property

All content, design, and software comprising the Service are the property of Taxpipe. You retain ownership of the data you submit through the Service.

6. Limitation of Liability

6.1 Nothing in these Terms excludes or limits Taxpipe's liability for (a) death or personal injury caused by our negligence, (b) fraud or fraudulent misrepresentation, or (c) any other liability that cannot be excluded or limited under the laws of England and Wales.

6.2 Taxpipe is not a firm of accountants or tax advisers, and the Service does not constitute tax or accounting advice. The Service is a software tool for preparing and filing the CT600 to HMRC. You are responsible for the accuracy of the information you provide, for the correctness of your return, and for all of your own filing obligations, including any Companies House filings (see clause 2a).

6.3 Subject to clause 6.1, Taxpipe shall not be liable, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, for any of the following, whether direct or indirect: loss of profit, revenue, or anticipated savings; loss of business, goodwill, or reputation; or any penalties, interest, fines, or charges imposed by HMRC, Companies House, or any other third party. Taxpipe shall also not be liable for any indirect, special, or consequential loss.

6.4 Clause 6.3 does not exclude Taxpipe's liability for any penalties, interest, fines, or charges that are caused directly by a defect in the Service (as opposed to errors in the information you provide); such liability is instead limited by clause 6.5.

6.5 Subject to clauses 6.1 and 6.4, Taxpipe's total aggregate liability arising out of or in connection with the Service and these Terms, whether in contract, tort, or otherwise, shall not exceed the greater of (a) the total fees actually paid by you to Taxpipe in respect of the return(s) giving rise to the claim, or (b) £250.

6.6 Each limitation and exclusion in this clause 6 operates separately. If any of them is held to be unenforceable, the remainder shall continue to apply.

7. Termination

We may suspend or terminate your access to the Service at any time if you breach these Terms. You may stop using the Service at any time.

8. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will notify you by email or by posting a notice on the Service, and where appropriate we will ask you to accept the updated Terms before you continue to use the Service. Your continued use of the Service after changes take effect constitutes your acceptance of the updated Terms.

8a. Entire Agreement and Non-Reliance

These Terms constitute the entire agreement between you and Taxpipe in relation to the Service and supersede all prior statements, representations, understandings, and marketing communications. You acknowledge that you have not relied on any statement, representation, or assurance that is not expressly set out in these Terms. Nothing in this clause limits or excludes any liability for fraud or fraudulent misrepresentation.

9. Governing Law

These Terms are governed by and construed in accordance with the laws of England and Wales. Any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales.
