Please read these Terms of Service (“Terms”) carefully. By accessing, browsing, creating an account, or continuing to use www.deductic.com (the “Website”), you agree to be bound by these Terms, together with any terms incorporated by reference (including our Privacy Policy). If you do not agree to these Terms, you must not use our Website or Services.
These Terms apply to your access and use of the Website and all services made available through it (the “Services”), provided by Deductic Ltd (“Deductic”, “we”, “our”, or “us”). We may amend these Terms from time to time in accordance with section Changes to these Terms.
We operate an online platform of automated professional advisory service. This includes automated advisory products for determining IR35 status, tax residency, and domicile. This also includes an online software-as-a-service (“SaaS”) tax return preparation and filing service for individuals seeking to file their UK personal tax return with Her Majesty’s Revenue & Customs (“HMRC”), as well as Making Tax Digital for Income Tax Self Assessment (“MTD for Income Tax” or “MTD ITSA”). Where applicable, the Services may connect to HMRC systems using official HMRC interfaces and APIs.
In these Terms, “Account” means the account you register on the Website. “Digital Records” means the income and expense records you maintain digitally for MTD ITSA. “Quarterly Updates” means the periodic submissions you (or your agent) send to HMRC under MTD ITSA. “Final Declaration” and/or “End of Period Statement (EOPS)” mean the finalisation step(s) required to complete the tax year under MTD ITSA. “Submission” means any filing or transmission to HMRC made via the Services, including Quarterly Updates, end-of-year finalisation submissions, and any Self Assessment tax return submissions that may still be required. “User Content” means the information, records, and data you enter into or upload to the Services.
We operate an online software platform that may enable users to create and maintain digital records, prepare and submit Quarterly Updates to HMRC, and complete end-of-year finalisation processes such as EOPS and the Final Declaration where applicable. The platform may also present summaries and estimates generated from the data you enter, though these may not represent final liabilities. In addition, where supported, the Services may include preparation and filing of a UK Self Assessment return, including situations where a user must file outside MTD ITSA or prior to joining MTD ITSA. We may also offer automated advisory tools, for example relating to tax residency, domicile, and employment status, which provide outputs based on the information you provide. Unless you explicitly purchase a service described as expert advice or assisted filing, you understand that the Services are software and automated outputs and are not a substitute for advice from a qualified accountant or tax adviser.
It is free for users to register an account and to input all their relevant information on to our Website. A legally binding agreement between you and Deductic is formed when you complete registration and/or begin using the Services. You must provide accurate information when registering and keep your details up to date.
To use Services that connect to HMRC systems, you may be required to sign in using HMRC login details and/or grant authority for Deductic to interact with HMRC on your behalf, including transmitting Submissions such as Quarterly Updates and end-of-year finalisation submissions. By using the Services, you authorise Deductic to transmit Submissions to HMRC based on your actions and the information you provide. You remain responsible for maintaining your access to your HMRC account and keeping your credentials secure. You also acknowledge that HMRC may reject, delay, or fail to process Submissions due to technical issues, outages, eligibility rules, or validation checks, and Deductic cannot guarantee acceptance of any Submission. You acknowledge that HMRC may change requirements, technical specifications, and integration processes at any time.
Deductic charges fees for certain features and services, including but not limited to submitting to HMRC, unlocking MTD submission functionality, generating certificated results, subscriptions, and/or assisted services. Fees are displayed on the Website or at checkout and are payable in advance unless stated otherwise. Unless expressly stated, all fees are exclusive of VAT where applicable and VAT will be displayed at checkout if charged.
Where Deductic offers expert-assisted services, the appointment fee, for example £100, is for the specific appointment time selected by you. You acknowledge and agree that failure to attend an appointment or late cancellation may result in loss of the appointment fee, except where consumer protection laws require otherwise. Where you request an appointment or digital service to begin within 14 days of purchase, you consent to immediate performance of the service. Where the law permits, you acknowledge that cancellation rights may be limited once the service has been fully performed.
Refunds are processed in accordance with the refund terms shown at purchase and any applicable consumer protection laws. If you believe you were charged incorrectly, you should contact support@deductic.com.
You must be at least 18 years old and capable of entering into a legally binding contract to use the Services. You agree to provide information accurately, completely, and honestly and to keep your Account credentials confidential and secure. You must take appropriate steps to prevent unauthorised access to your Account and must promptly change your password and notify us if you suspect any unauthorised access. You acknowledge that the outputs, estimates, and filings produced by the Services depend on the accuracy and completeness of the information you provide and that you remain responsible for your tax affairs even when using the Services.
You must not use the Website or Services unlawfully, fraudulently, or maliciously. You must not attempt to access the Website or Services without authorisation, introduce malware, attack or disrupt the Website, reverse engineer any portion of the Website or Services, or copy, scrape, or reproduce the platform’s code, databases, designs, architecture, user interface, or flow. You must not use the Services to build, take steps to build, or help a third party build a competing product or service. You must not register accounts on behalf of other users without Deductic’s prior written permission.
If you are within the scope of MTD ITSA, you may be required to keep digital records, send Quarterly Updates for each income source, and complete end-of-year finalisation. You understand that Quarterly Updates are not final tax bills and do not represent your final tax position, and that end-of-year finalisation may require additional information such as reliefs, claims, adjustments, and non-business income. You agree to review and confirm all information before any Submission is made to HMRC. You acknowledge that MTD ITSA has been introduced in phases beginning from 6 April 2026 and that your obligations depend on HMRC eligibility rules and your circumstances.
Deductic processes personal information in accordance with its Privacy Policy. By using the Services, you agree that Deductic may collect and process your User Content to provide the Services and may use aggregated and anonymised data for product improvement where lawful. You confirm that you have the right to provide any data you upload and that you will not upload data unlawfully or in breach of another party’s rights.
The Website is made available online and may experience downtime, maintenance, errors, and interruptions. Deductic does not guarantee that the Services will be uninterrupted, error-free, compatible with all devices or browsers, or continuously available. Deductic may change, update, suspend, or withdraw features of the Services in order to maintain compatibility with HMRC requirements, enhance security and performance, and comply with legal and regulatory changes.
Deductic is the owner or licensee of all intellectual property rights in and to the Website and Services, including source code, software, databases, designs, layouts, platform architecture, trademarks, branding, and content. You are granted a limited, revocable, non-transferable licence to use the Services for your personal use and your own tax compliance, subject to these Terms. You may link to our home page provided you do so fairly and lawfully, without damaging our reputation or implying endorsement or association.

Deductic may suspend, restrict, or terminate your Account temporarily or permanently if you breach these Terms, if Deductic reasonably suspects fraud, misuse, or unlawful activity, or if Deductic needs to protect the security and integrity of the Services. If your Account is restricted, you may contact support@deductic.com to request the reason for the restriction.
You are responsible for ensuring that all information you input into the Services is accurate, complete, and truthful and for reviewing information before any Submission is made to HMRC. Any summaries, estimates, or projections provided through the Services are for information only and may not reflect your final tax position. HMRC may calculate tax differently after processing, applying validation rules, adjustments, or its interpretation of the law.
To the maximum extent permitted by law, Deductic is not liable for losses resulting from inaccurate or incomplete information provided by you, HMRC outages or system errors, delays, failed transmissions, rejections, third-party system failures, or any losses arising from viruses, unauthorised access, or data loss not caused intentionally by Deductic. Deductic is not liable for indirect, incidental, consequential, or special losses, including loss of profits, revenue, income, business, goodwill, or anticipated savings.
Where you have paid for a Submission or certificated result, Deductic’s responsibility is limited to ensuring that the software performs calculations based on the data you entered and attempts to transmit Submissions you instruct it to submit in accordance with the product description. To the maximum extent permitted by law, Deductic’s aggregate liability arising from or in connection with these Terms and the Services is limited to the total amount of fees you paid to Deductic in the 12 months preceding the event giving rise to the claim. Nothing in these Terms excludes or limits liability where it would be unlawful to do so, including liability for death or personal injury caused by negligence, fraud, or fraudulent misrepresentation.
You agree to indemnify and hold harmless Deductic against any claims, losses, liabilities, costs, and expenses, including reasonable legal fees, arising out of or in connection with your misuse of the Services, breach of these Terms, or submission of inaccurate, unlawful, infringing, or unauthorised data.
The Website may contain links to third-party websites, services, or resources, including HMRC systems. These are provided for your information only. Deductic has no control over third-party systems and is not responsible for their content, availability, performance, or functionality.
Deductic may update these Terms from time to time and the “Last Updated” date will reflect the current version. By continuing to use the Website or Services after changes become effective, you agree to the updated Terms. If you do not agree to the updated Terms, you must stop using the Website and Services. If any provision of these Terms is found invalid or unenforceable, the remaining provisions will remain in effect and a valid provision that best reflects the original intent will be substituted where permitted.
