Legal
Terms of Use
Last updated 19 August 2026. These Terms are our contract with you. Please read them — by creating an account or using TaxCheckIt you agree to them. If you can't agree, please don't use the Service. Bold words have the same meaning throughout.
1. Who we are and who you are
In short: TaxCheckIt is run by Kael Tripton Ltd in London. 'You' includes the business you act for.
We / us / TaxCheckIt means Kael Tripton Ltd, a company registered in England and Wales (company number 17177071, ICO registration ZC135439), registered office 71-75 Shelton Street, Covent Garden, London WC2H 9JQ. You / your means you and any business, organisation or client you are authorised to represent. Service means taxcheckit.co.uk, the TaxCheckIt web application, the free lookup tools and everything we provide through them now or in future.
2. What the Service is — and isn't
In short: We're software, not accountants. You are responsible for your figures and filings.
- TaxCheckIt helps you keep digital records, prepare figures and, where enabled, send returns and updates to HM Revenue & Customs (HMRC) through HMRC's Making Tax Digital (MTD) APIs. It also provides free lookups that query public HMRC services.
- No professional advice. We are not accountants, tax advisers, solicitors or a regulated firm. Nothing in the Service — including guides, estimates, checks or prompts — is tax, legal, accounting or financial advice. Estimates such as "tax so far" are indicative, use simplified assumptions and your own data, and must not be relied on.
- Your filings are yours. You (or your agent) are solely responsible for the accuracy and completeness of data entered or imported, for reviewing figures before submission, for the decision to submit, and for meeting HMRC deadlines. We do not check your affairs for correctness and we do not act as your agent with HMRC.
- Lookups. VAT-number, EORI and similar checks reflect what HMRC's service returned at the time of the query. We don't warrant that a reference is valid for any purpose; keep HMRC's consultation reference and make your own checks.
- HMRC recognition. Until TaxCheckIt is listed by HMRC, it is not HMRC-recognised software; we'll state clearly in the Service when, and for which taxes, recognition applies. HMRC does not endorse software.
3. Your account
In short: Be 18+, keep your sign-in safe, give accurate details, manage who you invite.
- You must be 18 or over and authorised to act for the business or individual whose data you enter. Agents must hold the appropriate HMRC authorisations for each client.
- Sign-in is by one-time email link; keep that mailbox secure. You're responsible for activity under your account and for anyone you invite. Tell us immediately at [email protected] if you suspect unauthorised access.
- Keep your contact details, organisation details and VAT number accurate — they appear on invoices and HMRC submissions.
- Don't put card numbers or passwords into free-text fields.
4. Connecting to HMRC
In short: You authorise us with HMRC; HMRC's rules and uptime are outside our control.
When you connect, you authorise TaxCheckIt to access and submit data on your behalf via HMRC's APIs, using only the permissions you grant on HMRC's own authorisation screen. You can revoke this at any time in your HMRC online account or by disconnecting in the Service. HMRC's terms, availability and processing apply to all interactions with HMRC; we are not responsible for HMRC outages, rejections, assessments, penalties or interest. We are required by HMRC to send fraud-prevention headers (device and connection data) with every API call — see our Privacy Notice; this is a legal requirement of using HMRC-connected features.
5. Plans, fees and refunds
In short: Free is free. Paid plans bill in advance; cancel any time; 14-day refund on annual plans if you haven't filed.
- Free features are provided free of charge and may have fair-use limits. Paid plans are billed monthly or annually in advance, as shown at checkout, inclusive of VAT where applicable. Subscriptions renew automatically until you cancel.
- You may cancel at any time in the Service; access continues to the end of the paid period. Monthly fees are not refunded. Annual plans are refundable in full if you cancel within 14 days of first purchase and no submission has been made to HMRC through the Service in that time; otherwise annual fees are non-refundable. Consumers keep their statutory cancellation rights.
- We'll give at least 30 days' notice by email before any price increase takes effect for you. If a payment fails we may suspend paid features after 7 days and cancel after 14.
6. Your data
In short: You own your data; we use it to run the Service; export any time; we keep what the law requires.
- You own the data you enter or import. You grant us a licence to host, copy, process, back up and transmit it as needed to provide, secure, support and improve the Service, to send it to HMRC and recipients you choose (e.g. invoice customers), and to create anonymised aggregate statistics.
- Personal data you enter about your own customers, suppliers or clients is yours to control; we process it for you as your processor under the data-processing terms in our Privacy Notice.
- You can export your data at any time. On account closure we delete or anonymise data within 90 days, except records we must keep by law (submission payloads, HMRC receipts, invoices, audit logs — 6 years).
- Back up what matters to you; we are not a document archive.
7. Acceptable use
In short: Lawful business use only; don't abuse, scrape, or attack the Service or HMRC.
You must not: use the Service for unlawful purposes or to submit information you know to be false; access or attempt to access other users' data; reverse engineer, scrape, copy or resell the Service; use lookup tools in bulk or by automated means beyond published limits; upload malware; interfere with HMRC systems; or be abusive to our staff. We may apply fair-use limits and will ask you to stop before acting, except where the risk is immediate.
8. Intellectual property
In short: We own the Service; you get a licence to use it.
We (and our licensors) own all rights in the Service, its design, code, content and trade marks. We grant you a non-exclusive, non-transferable licence to use it under these Terms while your account is active. You keep all rights in your data. If you send us feedback we may use it without restriction.
9. Availability, changes and beta features
In short: We aim for high uptime but can't guarantee it; features may change; betas are at your risk.
We try to keep the Service available 24/7 and to tell you about planned maintenance. We don't guarantee uninterrupted access. We may add, change or withdraw features; for paid features we give reasonable notice where practicable. Features marked beta, preview or early access are provided as-is and may change or be withdrawn. Support is by email in UK business hours.
10. Security
In short: We protect data with appropriate measures; you keep your side secure.
We use appropriate technical and organisational measures — encryption in transit and at rest, encrypted storage of HMRC tokens, access controls and audit logs. No system is completely secure; we will notify you and regulators of qualifying incidents as the law requires. You must keep your devices, email account and sign-in secure and use any security features we offer.
11. Warranties, liability and indemnity
In short: As-is Service; we're not liable for HMRC penalties or indirect loss; liability capped; you cover third-party claims caused by your use.
- The Service is provided "as is". To the fullest extent permitted by law we exclude all implied warranties.
- Nothing limits liability for death or personal injury caused by negligence, for fraud, or for anything that cannot be limited by law. Consumers' statutory rights are unaffected.
- Subject to that, we are not liable for: loss of profit, revenue, business, goodwill or anticipated savings; penalties, surcharges, interest or assessments imposed by HMRC or any authority; tax, legal or accounting compliance issues; loss or corruption of data beyond reasonable efforts to restore from our backups; or any indirect or consequential loss.
- Our total aggregate liability to you in any 12-month period is limited to the greater of £100 and the fees you paid us in that period.
- You indemnify us against third-party claims, losses and costs (including reasonable legal costs) arising from your breach of these Terms, your data, or your unlawful use of the Service, except to the extent caused by our breach or negligence.
12. Suspension and termination
In short: You can leave any time; we can suspend or end accounts for breach, non-payment, risk or legal reasons.
You may close your account at any time. We may suspend or terminate your access immediately if you breach these Terms and don't fix it within 14 days of notice (or the breach can't be fixed), for non-payment under section 5, if required by law, regulator or HMRC, or where we reasonably believe there is a security, fraud or legal risk. We may otherwise end the Service or these Terms with 30 days' notice. Sections 2, 6, 8, 11 and 13 survive termination.
13. General
In short: English law; talk to us first; we'll give notice of material changes; the usual housekeeping.
- Disputes. Contact [email protected] first — most issues are resolved quickly. These Terms are governed by the law of England and Wales and the courts of England and Wales have exclusive jurisdiction; consumers resident in Scotland or Northern Ireland may bring proceedings locally.
- Changes. We may update these Terms. Changes aren't retrospective. For material changes we'll give at least 30 days' notice by email or in the Service; if you don't accept them you may close your account before they take effect.
- Notices. To us: [email protected]. To you: the email on your account.
- Events outside our control. Neither of us is liable for delay or failure caused by events beyond reasonable control, including HMRC or third-party service failures.
- Other. If part of these Terms is unenforceable, the rest stands. We may transfer these Terms to a successor business with notice to you. Nothing creates a partnership, agency or employment relationship. These Terms and the Privacy Notice are the whole agreement between us for the Service.
