The terms you accept before using the Suite.

TIF Suite terms of use

Last updated: 31 August 2026. These terms apply from 31 August 2026. Version: 2026-08-31-IE.

Which of our companies you are contracting with. These terms apply where your contracting entity is TIF Synergy Ireland Limited.

From 28 August 2026 to 13 September 2026 your contracting entity is TIF Synergy Ireland Limited wherever your organisation is established, including in the Netherlands, and these are the terms that apply to you.

From 14 September 2026 a second set of terms becomes available for organisations established in the Netherlands, under which the contracting entity is Blauw Belastingen B.V., published at https://www.tifsynergy.com/legal/nl/terms-of-use/. If your organisation is established in the Netherlands your contracting entity changes to Blauw Belastingen B.V. only when those terms are in force and you have accepted them. Until then these terms continue to apply to you. When you accept them, these terms end for your organisation and the Blauw terms apply to you from that point onwards. Nothing agreed under these terms before that date is undone, and any clause of these terms that is stated to continue after they end continues.

The documents that go with these terms, and where to find them.

• Schedule DP, our data-processing schedule, with its annexes 1 and 3, published at https://www.tifsynergy.com/legal/ie/data-processing-schedule/2026-08-31-IE/. It forms part of these terms. That address always shows the version that goes with these terms.
• Annex 2 to Schedule DP, our sub-processor list, published at https://www.tifsynergy.com/legal/sub-processors/. It changes under clause DP6 and carries its own version identifier, so that address always shows the current list. Every earlier version stays available at that address followed by that version's identifier.
• Our tool privacy notice, published at https://www.tifsynergy.com/legal/ie/privacy/. It is not part of these terms. It tells you how we handle personal data, and that address always shows the current notice.

How we decide whether your organisation is established in the Netherlands is set out at clause DP1.5 of the data-processing schedule we publish separately and link from these terms. That decision does not change unless we agree it with you in writing.

These terms govern your use of the TIF Suite tool you are using. Please read them before you use the tool. By using the tool you accept these terms. If you do not accept them, do not use the tool.

The tool is provided by TIF SYNERGY IRELAND LIMITED, a private company limited by shares incorporated in Ireland, registered number 821025, registered office 77 Camden Street Lower, Dublin, D02 XE80, Ireland, VAT identification number IE4760769WH, referred to in these terms as "TIF", "we" or "us". "You" means the organisation on whose behalf you use the tool and you confirm you are authorised to accept these terms for that organisation.

The tools are developed and provided by Blauw Belastingen B.V., trading as TIF Synergy, a private limited company incorporated in the Netherlands, KvK 58905375, and are supplied to you under these terms by us. Blauw operates the tools for us. The data-processing schedule we publish separately explains what that means for the data you put into a tool.

These tools are for business users. They are provided only to organisations and to people using them in the course of a business, a profession or a trade. They are not offered to consumers and they are not intended for personal use. If you are not using the tool for the purposes of an organisation, do not use it.

3.1 The tool is a working aid. The tool is a working aid for a qualified person. It helps you do part of a task faster and more consistently. It is not a service that produces a finished answer, it does not complete the task for you and its output is a starting point for your own work, never the end of it.

3.2 The output is yours to review and to stand behind. Everything the tool produces is your output. You are responsible for reviewing it, for correcting it and for deciding whether to rely on it. Where the output feeds a tax return, a computation, a filing, a disclosure, a set of documentation or any position taken with a tax authority, that position is yours. We do not take the tax position. The tax treatment stays with your qualified adviser: it stays theirs to set, not one we have taken for them.

3.3 Nothing in the tool is tax advice. Nothing the tool displays, generates, suggests, calculates or stores is tax, legal, accounting or other professional advice and no part of it is a substitute for advice from a qualified adviser in the relevant jurisdiction. Using the tool does not create an adviser and client relationship between you and us and it does not extend any engagement you may separately have with us. If we are separately engaged by you under a written engagement letter, that engagement is governed by its own terms and not by these.

4.1 Some parts of the TIF Suite use artificial intelligence. Where a tool or a feature is AI-assisted, that is stated in the tool itself at the point where you interact with it and it is stated in the schedule for that tool at the end of these terms.

4.2 AI-assisted output can be wrong, incomplete or out of date, including where it appears confident and well-sourced. Check every result against its cited source before you rely on it. Where the tool shows you a source, the source governs, not the tool's summary of it.

4.3 We do not warrant that AI-assisted output is accurate, complete, current or fit for any particular purpose. Clause 3 applies to AI-assisted output in full.

4.4 This clause is a description of how the tools work. It does not replace any notice we are required to give you in the interface itself and it is not intended to satisfy one.

5.1 We grant you a non-exclusive, non-transferable, revocable right to use the tool for your own internal business purposes and for the internal purposes of your group, for as long as these terms are in force.

5.2 Licence fees. We do not charge a licence fee for the tools made available to you under these terms and we will not introduce one for the version of a tool licensed to you under these terms, except where we have agreed a licence or subscription fee with you in writing in an order form, a statement of work or an engagement letter. Each of those means a document that names the tool, the fee and the period it covers, and that both of us have signed or accepted in writing. Nothing else introduces a fee, and using a tool never does. Implementation, configuration, data migration, training, support and any advisory or consulting services are separate paid services, agreed with you in writing before any work starts. Those services are not governed by these terms.

5.3 You must not: resell, sublicense or provide the tool as a service to a third party; copy, reverse-engineer or attempt to derive the source code, models, prompts, templates or methodology behind the tool, except to the extent that restriction is unenforceable by law; use the tool to build a competing product; or remove or obscure any notice, attribution, citation or disclaimer the tool displays.

5.4 All intellectual property in the tool, in the TIF Suite, in our templates, mappings, methodology and content remains ours or our licensor's. All intellectual property in the data and content you put into the tool remains yours. Nothing in these terms transfers ownership of either.

6.1 You are responsible for the accuracy, completeness and lawfulness of everything you put into the tool and for having the right to put it there.

6.2 You must have a qualified person review the output before you rely on it, file it, disclose it or provide it to a third party or a tax authority.

6.3 You must keep your own records. The tool is not your system of record and it is not your books and records for tax or accounting purposes. You remain responsible for retaining the records the law requires you to retain, for the period it requires, in a form you control. Do not rely on the tool as the only copy of anything you are required to keep.

6.4 You are responsible for your users, for keeping access credentials secure and for the activity that happens under your account.

6.5 Acceptable use of AI-assisted features. Where a tool has an AI-assisted feature, that feature runs on a third-party AI platform whose own terms restrict what may be sent to it and what may be generated with it. You must not use an AI-assisted feature, and must not permit your users to use one, in a way that breaches those restrictions. The data-processing schedule for the tool says where to find them. If our platform provider restricts, suspends or withdraws our access because of content sent from your account, we may suspend your access to the affected feature under clause 9.4 while we deal with it, and we will tell you why.

7.1 We do not commit to any service level, uptime or support response time under these terms, unless we have separately agreed one with you in writing. Whether a licence fee is payable is a separate question and clause 5.2 answers it.

7.2 We may change, suspend or withdraw a tool or a feature. Where a change materially reduces the functionality you use, we will give you reasonable notice and at least 60 days' notice before withdrawing a tool entirely, except where we have to act sooner for security, legal or safety reasons.

7.3 We may change these terms. If we make a material change we will tell you before it takes effect and we will publish the date the change applies. Continuing to use the tool after that date means you accept the change. If you do not accept it, stop using the tool and ask us to close your account.

8.1 Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for liability for defective products so far as that liability cannot be limited or excluded, for damage caused by intent or conscious recklessness on our part or on the part of those charged with managing our business, or for anything else that cannot be limited or excluded by law.

8.2 The tools are provided "as is" and "as available". To the fullest extent permitted by law we exclude all warranties, conditions and terms implied by statute or common law, including as to accuracy, completeness, satisfactory quality or fitness for a particular purpose.

8.3 We are not liable for: any tax, interest, penalty, surcharge or other liability arising from a position you take, a return you file or a disclosure you make; any loss arising because you relied on output without the review required by clause 6.2; loss of profit, revenue, goodwill or anticipated savings; or any indirect or consequential loss.

8.4 Our total liability to you in connection with the tool, in aggregate and however arising, is limited to the greater of EUR 1,000 and the amount you have paid us or any company in our group for services connected with the tool in the twelve months before the claim. Our group means us, any company that controls us, any company we control and any company under common control with us. It includes Blauw Belastingen B.V. This is only a way of calculating the limit. It does not make any company in our group a party to these terms and it does not give you any right against them under these terms.

8.5 This clause 8 does not apply to any separate written engagement between us for advisory, implementation or other services. That engagement carries its own liability terms.

9.1 How we handle personal data in connection with the tools is set out in our tool privacy notice, which we publish on our website and link from these terms, and, where we process personal data on your behalf, in the data-processing schedule at Schedule DP, which we publish on our website as a separate document and link from these terms, which forms part of these terms.

9.2 We do not train on your content. We treat the content you put into the tool as confidential. We do not use it to train, fine-tune or improve any artificial-intelligence model, ours or anyone else's. The service providers listed in the data-processing schedule are engaged under written terms restricting them to processing on documented instructions and none of them is instructed to use your content for training, fine-tuning or model improvement. One of those providers also carries out security and abuse screening as part of providing the service, which is not something we instruct and which we cannot switch off. That is described at clause 9.2.1 and in the schedule. We do not sell your content and we do not disclose it to anyone else except those providers and where the law requires us to.

9.2.1 What our AI provider does do. Where a tool has an AI feature, the provider that runs that feature screens what is sent to it for abuse and misuse. The provider's own terms say that, as part of providing the service, it temporarily stores what is sent to it and what it sends back for that purpose. Where its automated systems flag something, its authorised employees may review that content to investigate and verify potential abuse. For a deployment inside the provider's EU data boundary, the provider's terms commit that those employees are located in the European Economic Area. We do not tell you here that every deployment we use sits inside that boundary. The data-processing schedule we publish separately says, tool by tool, where a tool's requests are processed, and it identifies the features whose requests may be processed outside the European Economic Area. The provider's published documentation describes a narrower ordinary practice, under which flagged content reviewed by automated means is not additionally stored and under which a review by a person is the exception. Where the provider's contract terms and its documentation differ we state the contract terms. Where content is stored for that purpose, the provider's published position is that the store sits in the geography our resource is in. That screening is a security measure and it is not training. The schedule for each tool says whether the tool has an AI feature and the privacy notice describes this in full.

9.3 Getting your content out. You may stop using the tool at any time. On termination or withdrawal we will give you a reasonable opportunity, and at least 30 days, to get your content out before we delete it. Where the tool has a self-service export you can use it yourself. Where it does not, ask us and we will provide your content in a structured, commonly used, machine-readable format within that period. The schedule for each tool says which applies today. See clause 6.3: exporting on exit does not replace keeping your own records as you go.

9.4 We may suspend or close your account if you breach these terms or if we are required to by law. We do not close accounts for inactivity. If we introduce an inactivity period we will publish it in these terms and tell you before it applies to your account.

10.1 These terms, together with the schedules, are the whole agreement between us about the tool. 10.2 If a court finds any part of these terms unenforceable, the rest continues to apply. 10.3 Nothing in these terms creates a partnership, agency or employment relationship between us. 10.4 These terms are governed by the law of Ireland. The courts of Ireland have exclusive jurisdiction over any dispute arising out of or in connection with these terms, their subject matter or their formation. 10.5 Questions about these terms: info@tifsynergy.com.

What TaxLex is. TaxLex is an AI-assisted tax research aid. It searches an indexed corpus of primary source material across multiple jurisdictions and shows you the source paragraphs relevant to your query, with a citation back to each one.

What TaxLex does not do. TaxLex does not give you the answer. It shows you where to look. It does not confirm that a source is current, complete or applicable to your facts, it does not interpret a source for your circumstances and it does not tell you what position to take. Coverage of a jurisdiction does not mean coverage is complete for that jurisdiction and the absence of a source from a result does not mean no such source exists.

AI-assisted. Yes. TaxLex uses AI to retrieve and present source material. Clause 4 applies in full, and so does clause 9.2.1. Always read the cited source itself. Where the tool's summary and the cited source differ, the source governs.

What TaxLex keeps. TaxLex keeps the text of your questions. You can delete a chat yourself at any time. Your chat history, meaning your questions and the answers to them, is kept for up to 24 months from the last message in that chat, which is the longest a chat you have not deleted is kept rather than a period we hold it for. A separate short record of each question asked, shortened to the first 1000 characters, is kept for 90 days for our own quality checks. Your questions are content: treat a question you type into TaxLex the same way you would treat any other client information. The privacy notice sets out in full what is kept and for how long.

Getting your content out. TaxLex exports one answer at a time to Word, PowerPoint or Excel. There is no self-service export of your full history or your uploaded library. Clause 9.3 applies: ask us and we will provide it. You can delete a chat yourself but you cannot export your history yourself, so export what you need before you delete it. Clause 6.3 applies: the tool is not your system of record.

What TaxTag is. TaxTag provides scalable templates for tax documentation, including transfer-pricing master file and local file. It automates the mechanical, repeatable parts of producing that documentation and applies changes consistently across templates.

What TaxTag does not do. TaxTag does not perform the underlying analysis. It does not carry out a functional analysis, a risk analysis, a comparability analysis or a benchmarking study and it does not determine an arm's-length outcome. It does not confirm that the documentation it helps you produce meets the local requirements of any jurisdiction or that it satisfies any filing or penalty-protection standard. Every document produced with TaxTag requires entity-specific review before it is filed or relied on and you are responsible for confirming that each entity's facts, functions, risks and substance are correctly reflected.

AI-assisted. Yes, in one place: tag suggestion. When you upload a document to be tagged, the text of that document is sent to our AI provider, which proposes tags for passages in it. A suggested tag is a proposal, not a determination. Nothing is applied to your document unless you tick it, either row by row or with "accept all", and save. Nothing is ticked for you. Clause 4 applies in full, and so does clause 9.2.1.

Before a document is sent you are asked one question. You must say whether the document contains real client data. If you say it does, or if the question is not answered, the tool refuses to send it and you tag the document by hand instead. That answer is yours and we rely on it. The tool does not open your document and work out for itself whether the answer is right. If you tell it a document is a sample when it is not, the document is sent.

Getting your content out. TaxTag downloads one template or one set of generated documents at a time. There is no self-service export of your templates as a set, your tag mapping or your account data. Clause 9.3 applies: ask us and we will provide it.

What TaxMap is. TaxMap is an account-mapping aid. It maps source accounts, such as a general ledger or a trial balance, to the categories a given tax process needs and lets you reuse that mapping across cycles and across tax areas.

What TaxMap does not do. TaxMap does not determine tax treatment. It records the mapping you configure, it does not decide what the correct mapping is and it does not validate a mapping against the law of any jurisdiction. A mapping is a structure, not a position. The mapping and everything derived from it must be reviewed by a qualified person before it feeds a computation, a return or a reported figure.

AI-assisted. Not today, and that is changing. TaxMap's column-matching suggestions are made by comparing the column names against a fixed dictionary and by ordinary text matching, with no model involved, and nothing you put into TaxMap is sent to an AI provider. A mapping-proposal feature that does use AI is being built and will be made available. When it is, the names of your columns and the mapping structure you have configured are sent to our AI provider, and clause 9.2.1 applies to that. The figures, ledger lines and account balances in your file are not sent. A proposed mapping is a proposal, not a determination. Nothing is applied to your mapping unless you accept it, and nothing is accepted for you. Clause 4 applies in full. Nothing you put into TaxMap is used to train anything.

Getting your content out. TaxMap exports your mapped output to Excel or JSON, including the record of how each figure was mapped and transformed. You can do this yourself at any time.

What TaxTrack is. TaxTrack tracks and evidences tax workflows. It shows the status of the work your team puts into it, records status changes and sign-offs as they happen and gives you a live view and an audit trail across those workflows.

What TaxTrack does not do. TaxTrack evidences and operationalises your tax control framework: it does not constitute that framework and does not discharge the organisation's governance responsibilities. The control framework, its design, ownership and operation, remains yours. TaxTrack shows the status your team records in it, so it is only as accurate as what your team enters. It does not verify that a task was done correctly, it does not confirm a deadline is the correct deadline for your circumstances and it does not itself file anything or notify any authority. Meeting a filing obligation remains yours, whatever the tool displays.

AI-assisted. Not in the way people usually mean. TaxTrack has no chat, it does not write text for you and there is no large language model in it. It does use an automated document-reading service: when you upload an assessment notice, that service reads it and pulls out fields such as amounts, dates and names. What it pulls out is a proposal. It is shown to you and it only enters the record when a person confirms it. The service uses a standard, off-the-shelf model and your documents are not used to train it. Clause 4 applies to that reading step and so does clause 9.2.1.

Who can see what. TaxTrack shows who is responsible for a task and can group and filter your workflows by the person responsible. That means the tool holds and displays information about identifiable people in your organisation, including their email address alongside the tasks and deadlines assigned to them. Tell your people that.

Emails. TaxTrack emails the people in your organisation about work assigned to them, work that is due and work that is overdue. It can also email a person outside your organisation an invitation to fill in a questionnaire, if you send them one.

Getting your content out. TaxTrack has no self-service export today. Clause 9.3 applies: ask us and we will provide your content.
