Easy MTD EULA

Last updated 24 March 2026

IMPORTANT: READ THIS END USER LICENCE AGREEMENT CAREFULLY

This End User Licence Agreement (the 'EULA') is a legal agreement between you and Fly Software Limited ('Fly Software', 'we', 'us', or 'our') for the use of the Easy MTD software application, including any updates, patches, bug fixes, releases, documentation, and related materials that we provide with it or for it (together, the 'Software').

The Software is licensed, not sold. By downloading, installing, activating, accessing, or using the Software, you agree to be bound by this EULA. If you do not agree to this EULA, do not download, install, activate, access, or use the Software.

For the avoidance of doubt, Easy MTD is installed Windows desktop software and is not cloud-hosted software. Certain features of the Software may, however, require internet access in order to communicate with our systems and HMRC systems.

1. About this EULA

1.1 This EULA governs your use of the Software.

1.2 Additional terms may apply to certain features, websites, token purchases, support services, spreadsheets, partner materials, or third-party components. Where additional terms apply, they will supplement this EULA and, in the event of conflict, will prevail to the extent of that conflict in relation to the relevant item or service.

1.3 If you are entering into this EULA on behalf of a company, partnership, firm, or other legal entity, you represent and warrant that you have authority to bind that entity to this EULA. In that case, references to 'you' and 'your' mean that entity.

2. Eligibility and Permitted Users

2.1 You may use the Software only if you can lawfully enter into this EULA.

2.2 The Software is licensed to the person or legal entity that acquires it or is authorised to use it.

2.3 You must not make the Software available to any third party except as expressly permitted by this EULA.

2.4 Certain submission functionality within the Software requires the availability of valid usage credits, tokens, submission rights, or similar account entitlements issued or recognised by us ('Tokens'). If sufficient Tokens are not available, the Software may be unable to submit VAT returns, quarterly updates, final declarations, or other filings.

3. Licence Grant

3.1 Subject to your compliance with this EULA, we grant you a limited, revocable, non-exclusive, non-transferable, non-sublicensable licence to:

  1. install and use one copy of the Software on Windows devices owned or controlled by you; and
  2. use the Software solely for your own internal personal or internal business purposes, including for the purpose of preparing, reviewing, retrieving, handling, and submitting relevant data, returns, declarations, and filings on behalf of your own clients where you are authorised to do so.

3.2 For the avoidance of doubt, you may use the Software in the course of providing professional services to your own clients, provided that:

  1. you are properly authorised to act for those clients;
  2. your use remains under your control and for your own internal business purposes; and
  3. you do not make the Software itself available to clients or other third parties except as expressly permitted by this EULA.

3.3 This licence does not give you any ownership rights in the Software.

3.4 Unless we expressly agree otherwise in writing, the Software is licensed on a single-user / single-organisation use basis. You may use the Software for your own clients in accordance with clause 3.2, but you must not share, resell, relicense, sublicense, bureau-host, or otherwise make the Software itself available to any third party as a standalone product or hosted software service.

4. Tokens and Submissions

4.1 The Software may be downloaded or installed without charge, but certain submission features require Tokens or other paid entitlements.

4.2 Tokens are usage-based entitlements and do not transfer ownership of the Software.

4.3 We may implement reasonable technical controls, validation rules, eligibility checks, or account restrictions in relation to Tokens, submissions, or access to HMRC-connected functionality.

4.4 We may refuse, suspend, or block submissions where:

  1. required Tokens are unavailable;
  2. account status, technical integrity, security, or compliance checks fail;
  3. we reasonably suspect misuse, fraud, unauthorised use, or breach of this EULA; or
  4. HMRC systems, credentials, authority, or external services do not permit or complete the relevant submission.

5. Restrictions

5.1 Except to the extent expressly permitted by applicable law and incapable of lawful exclusion, you must not, and must not permit any other person to:

  1. copy the Software except for ordinary installation, loading, execution, and one reasonable back-up copy where necessary for lawful use;
  2. sell, resell, rent, lease, lend, distribute, sublicense, assign, publish, or otherwise make the Software available to any third party;
  3. reverse engineer, decompile, disassemble, translate, modify, adapt, vary, merge, or create derivative works of the Software;
  4. remove, alter, obscure, or interfere with any copyright notice, trade mark, branding, watermark, licence key, security feature, or proprietary marking;
  5. use the Software in any unlawful manner or in breach of HMRC requirements, third-party rights, or applicable regulations;
  6. bypass or attempt to bypass any authentication, licensing, token, security, or usage-control mechanism;
  7. use the Software in any way that could damage, disable, overburden, or impair the Software or any connected service or network; or
  8. use the Software with any third-party software, data source, automation, or workflow where doing so would breach the terms applicable to that third-party software or service.

5.2 You must keep all access credentials, account details, and device environments used with the Software secure.

6. Ownership and Intellectual Property

6.1 The Software is licensed, not sold, to you.

6.2 We and our licensors retain all intellectual property rights, title, and interest in and to the Software, including all copyright, database rights, trade marks, design rights, know-how, and all other proprietary rights in any part of the Software.

6.3 This EULA does not transfer to you any intellectual property rights other than the limited licence expressly granted under it.

6.4 Any feedback, suggestions, enhancement requests, recommendations, or ideas you provide regarding the Software may be used by us without restriction or obligation to you.

7. HMRC Connectivity and External Dependencies

7.1 The Software may connect to, interoperate with, or depend on HMRC systems, HMRC APIs, HMRC credentials, and related HMRC technical services in order to retrieve, validate, or submit relevant data.

7.2 Access to and use of HMRC-connected functionality may depend on valid credentials, HMRC authority, internet connectivity, HMRC service availability, and compliance with HMRC requirements.

7.3 We do not grant you any rights in HMRC systems, APIs, data, or services except as strictly required for your permitted use of the Software.

7.4 We are not responsible for the availability, operation, acts, omissions, security, performance, outage, delay, rejection, or failure of any HMRC system, HMRC API, or related HMRC service, or for any consequence arising from your internet connectivity or your credentials, authority, or access status in relation to HMRC.

8. Updates, Changes and Support

8.1 We may, but are not obliged to, provide updates, upgrades, enhancements, bug fixes, patches, or technical support for the Software.

8.2 Where we provide updates, those updates may be subject to this EULA or to additional terms notified to you at the time.

8.3 We may modify, suspend, withdraw, or discontinue any feature of the Software at any time, including where necessary for security, legal, regulatory, compatibility, technical, or commercial reasons.

8.4 Support, if provided, will be provided through the contact methods or support channels identified on easymtd.com or flysoftware.com, or such other channels as we may notify to you.
