About & Legal

Accuracy and sourcing

Every factual claim on CheckMyMTD — every threshold figure, deadline date, penalty amount, and exemption category — must be traceable to a primary source: HMRC published guidance at GOV.UK, UK primary legislation (Finance Acts, Income Tax Act 2007), or HMRC secondary legislation (statutory instruments). We do not publish claims that cannot be verified against a primary source.

Where HMRC guidance is ambiguous or subject to ongoing consultation, we say so explicitly. We do not present uncertain interpretations as settled facts.

Update policy

We monitor HMRC's GOV.UK pages, HMRC press releases, and the UK Parliament's legislation.gov.uk daily. When HMRC publishes new guidance, amends existing guidance, or announces a change to MTD ITSA scope or deadlines, we review and update all affected pages within 48 hours. The "Last updated" date on each guide page reflects the most recent material change to that page's content.

Distinction between guidance and advice

CheckMyMTD publishes general information about MTD obligations. Our calculator outputs and guide content describe how HMRC's published rules apply to defined scenarios — they are not tailored tax advice for any individual. We state clearly on every page that users should consult a qualified tax adviser for advice specific to their circumstances. This is not a disclaimer of responsibility alone; it reflects a genuine commitment to staying within our competence.

Affiliate content

Software comparison pages include affiliate links. We disclose this on every page where affiliate links appear. Affiliate relationships have zero influence on our rankings or recommendations — we apply the same evaluation criteria to every software provider regardless of whether we have an affiliate relationship with them. We test and verify HMRC approval status independently before recommending any software.

Independence

CheckMyMTD receives no payments from HMRC, accountancy firms, or government bodies. We are not part of any accountancy or tax software group. Our content is written entirely independently, and our ratings and recommendations cannot be purchased.

Corrections

If you believe any content on this site is factually incorrect or out of date, please contact us at [email protected]. We take corrections seriously and will review and respond within 3 working days. If a correction is substantiated, we will update the relevant page and note the correction.

CheckMyMTD takes your privacy seriously. This policy explains what data we collect, how we use it, and your rights.

Data we collect

Calculator data (localStorage only): When you use our MTD engine, your answers are saved to your browser's localStorage. This data never leaves your device and is never transmitted to our servers. It exists only to provide the "welcome back" return visitor experience. You can clear it at any time by clearing your browser's site data.

Email address (optional): If you choose to sign up for quarterly MTD reminders, we collect your email address. This is processed through MailerLite. Your email is used only to send MTD deadline reminders and will never be sold or shared with third parties. You can unsubscribe at any time via the link in any email we send.

Analytics: We use privacy-respecting analytics (Cloudflare Web Analytics) which does not use cookies and does not collect personally identifiable information. We see aggregate page views and general traffic data only.

Cookies

CheckMyMTD does not use tracking cookies. We use localStorage (not cookies) to save your calculator state. Google Fonts are loaded from Google's CDN — Google may set its own cookies in accordance with Google's privacy policy.

Third-party services

Google Fonts: Used for typography. Requests go to Google's servers — see Google's privacy policy at policies.google.com.

MailerLite: Email list management for reminder subscribers. See MailerLite's privacy policy at mailerlite.com/privacy-policy.

Affiliate partners: When you click software recommendation links (Xero, QuickBooks, FreeAgent, Zoho, Sage), you leave our site. We do not track your behaviour on those sites. Their privacy policies apply.

Your rights (UK GDPR)

You have the right to: access any personal data we hold about you; request deletion of your data; object to processing; and complain to the Information Commissioner's Office (ICO) at ico.org.uk. To exercise any of these rights, contact us through the Contact tab.

Data retention

Calculator data: stored locally in your browser, no server-side retention. Email addresses: retained until you unsubscribe. We do not retain email addresses of people who unsubscribe.

General information only

The content on CheckMyMTD, including the MTD compliance engine, situation guides, and all other pages, is intended to provide general information about Making Tax Digital obligations. It is not tailored to your individual circumstances and does not constitute tax advice, legal advice, accounting advice, or any other professional advice.

Not a substitute for professional advice

You should not rely solely on information from CheckMyMTD to determine your tax obligations. Tax law is complex and individual circumstances vary enormously. Always verify your specific obligations with HMRC directly (at gov.uk) or with a qualified tax adviser, accountant or Chartered Tax Adviser (CTA).

Accuracy and currency

We make every reasonable effort to ensure information is accurate and up to date based on current HMRC guidance. However, tax legislation and HMRC guidance changes frequently. We cannot guarantee that every piece of information on this site reflects the very latest legislative position at the time you read it. Always cross-reference with HMRC's own publications.

No liability

To the maximum extent permitted by law, CheckMyMTD, its operators, and its contributors accept no liability for:

• Any tax penalties, interest or surcharges you incur
• Any losses or damages arising from reliance on information provided on this site
• Any decisions you make based on the output of our calculator or guides
• Any inaccuracies in the information provided
• Any failure of the website, calculator, or export features

Calculator outputs

The MTD engine on CheckMyMTD is an indicative tool based on the information you provide and general rules. It cannot account for every nuance of your individual tax position. Outputs should be treated as a starting point for further investigation, not a definitive determination of your obligations.

Links to external sites

We link to third-party websites including GOV.UK, software providers and other resources. We are not responsible for the content, accuracy or availability of external sites. Links do not constitute endorsement beyond the software affiliate relationships described in our About page.

Affiliate relationships

Software recommendations include affiliate links. We receive a commission if you purchase through these links. This does not affect the price you pay. Our recommendations are based on profile matching, not commission rates.
