Terms of Use
Virtus is a professional research tool. Original sources remain the authority, and the service does not provide legal or tax advice.
Effective September 25, 2026
In short
- Virtus helps you find, read, compare, and cite public federal tax sources. It is not legal or tax advice, and you remain responsible for your professional judgment.
- The original government document controls. Sources can be outdated or superseded, and AI summaries, transcriptions, and difference highlights can be wrong.
- Your firm owns its content and annotations. We do not use them to train AI.
- Paid plans renew until cancelled. Our total liability is limited to the greater of the fees your firm paid in the prior 12 months or US$100.
- If a dispute cannot be resolved informally, it goes to binding individual arbitration with the American Arbitration Association. You and we give up jury trials and class or representative actions.
This summary is for convenience. The full text below controls.
Agreement and related documents
These Terms of Use govern access to Virtus, a service provided by Virtus Professional Services LLC (“we”, “us”). By using the service, you agree to these terms. If you use Virtus for an organization, you confirm that you are authorized to use its workspace and to accept these terms for your own use; the organization that holds the subscription (“your firm”) is also bound. A signed order form or enterprise agreement controls where it conflicts with these terms.
Our Privacy Notice and Cookie Policy are incorporated into these terms by reference. Together with any order form, they explain how the service works and how information is handled.
Please read sections 21 to 23 carefully. They require disputes that are not resolved informally to go to binding individual arbitration, and they waive jury trials and class and representative actions.
What the service provides
Virtus is a research library and workspace designed for approved United States federal tax primary sources. The current library contains IRS rulings. It can help authorized users find, read, highlight, compare, save, download, and cite available documents and use available research-assistance features. Additional source families may be added in the future. Current library coverage and feature availability are described in the service, and the library is not a complete collection of every document a government agency has issued.
Accounts
- Eligibility. You must be at least 18 years old and able to enter into a binding contract. Virtus is for professional and business use, not personal or household use.
- Accurate information. Give accurate, current, and complete information when you create an account, and keep it up to date.
- Keeping access secure. Use only the account assigned to you, and keep your password and sign-in methods secure. Tell us promptly at admin@virtusprofessionalservices.com if you suspect unauthorized use of your account. For help getting back into your account, write to support@virtusprofessionalservices.com. You are responsible for activity under your account.
- Organization accounts. Most access is through a workspace that belongs to your firm. Your firm controls its membership, roles, licensed seats, and any company sign-in it sets up, and its administrators can add, change, or remove your access. Each paid seat is for one named person and may not be shared, although your firm may reassign a seat when someone leaves. Your firm is responsible for the activity of the people it gives access to.
- Suspension. We may suspend or restrict an account as described in section 16, including to protect the service or other customers.
Permitted use cases and restrictions
You may use Virtus to research United States federal tax law in public IRS, Treasury, and court primary sources for your professional work and your clients. Research results are a starting point: check the official source before you rely on anything the service shows you.
You may not:
- scrape, crawl, bulk-download, bulk-export, or systematically extract content, or access the service by automated means other than features we provide;
- resell, sublicense, relabel, or share access to the service;
- copy, decompile, reverse engineer, or attempt to derive the service’s software or compilations, except where the law expressly allows it;
- get around usage limits, seat limits, safeguards on AI features, or security measures, or probe, overload, interfere with, or disrupt the service;
- access or attempt to access another workspace, account, or restricted record;
- upload, paste, or enter another person’s confidential information unless you have the authority to do so;
- use the service or its output as a substitute for your own professional judgment, or present generated, transcribed, or annotated product text as official government text;
- use the service or its output to build or train a competing product or AI system; or
- use the service unlawfully or to violate another person’s rights.
No legal or tax advice
Search results, summaries, citations, comparisons, related-document suggestions, and generated answers are research aids. They are not legal, tax, accounting, or other professional advice. Use of Virtus does not create an attorney-client, accountant-client, or advisory relationship with Virtus Professional Services LLC. You are responsible for checking the original sources, current law, and the advice of a qualified professional before relying on a result.
You alone are responsible for advice you give, returns and filings you prepare, and positions you or your clients take. Do not give generated output to a client or rely on it for a filing unless a qualified professional has reviewed it against the original source.
Sources and generated research
- The original document from the identified government source is the authority. Product summaries, extracted text, and transcriptions are not official documents.
- Source documents are provided as retrieved from their publishers. A document may be outdated, superseded, revoked, modified, incomplete, or later re-released with corrections, and the service may not reflect those changes right away.
- AI-generated answers and summaries may be incomplete or wrong, even when a citation is shown. Verify every material statement against its cited source and current law.
- Text transcribed from scans and other transcriptions are attributed working text. Scanned, mixed, or low-confidence pages may be unavailable for search or visibly marked for review.
- IRS rulings issued to particular taxpayers may not be used or cited as precedent under Internal Revenue Code § 6110(k)(3). Check the authority type and precedential status shown with each source.
Highlights, comparisons, and downloads
You can highlight and annotate documents, compare them, and download copies that include your annotations. An annotated download is your working copy: it keeps the original document and adds your marks, but it is not an official document, and you are responsible for how you use and share it. Difference highlighting compares the text of documents word by word. It shows textual differences and shared passages, not legal conclusions, and it can miss or overstate differences in scanned or unusually formatted pages.
Your content
As between you and Virtus Professional Services LLC, you or your firm own the questions, notes, highlights, folders, and other content you add to the workspace, and the output generated for you. You allow Virtus Professional Services LLC to process that content only as needed to provide, secure, and support the service. We do not use your content, questions, or annotations to train AI. If you send us feedback, we may use it without obligation to you.
Public sources and service materials
Government source documents remain subject to the rights and notices that apply to those materials. Virtus Professional Services LLC does not claim ownership of source documents merely because they appear in the library. The Virtus software, interface, compilations, and other service materials are owned by or licensed to Virtus Professional Services LLC. You may copy limited extracts for your own professional work and your clients.
Plans, fees, and renewal
If your firm buys a paid plan, fees are charged per licensed user and for any add-ons selected, at the prices shown when you order or in your order form. Prices exclude taxes, which your firm pays.
- Monthly and annual subscriptions renew automatically for the same period until cancelled. You can cancel at any time; cancellation takes effect at the end of the current period.
- Fees are non-refundable except where required by law or where we end the service without cause, in which case we refund prepaid fees for the unused period.
- Adding users or add-ons during a period may be charged for the rest of that period. We will give at least 30 days’ notice of a price change, which applies from your next renewal.
- If a payment fails and is not resolved after notice, we may suspend paid features until it is.
- Quoted add-ons and Enterprise plans follow the terms of their written quote.
- Send questions about invoices, payments, or seat changes, and any dispute about a charge, to billing@virtusprofessionalservices.com. Send remittance details to ar@virtusprofessionalservices.com.
Previews and illustrative records
Free access, trials, and the illustrative workspace may be limited, changed, or ended at any time. Illustrative records are labeled and are not real rulings.
Confidentiality
We treat your workspace content as confidential and use it only to provide the service, subject to the Privacy Notice and any disclosure required by law. You agree to keep non-public information about the service, such as unreleased features and security details, confidential.
Privacy and cookies
The Privacy Notice describes how account, workspace, research, browser, operational, and other applicable information is handled. The Cookie Policy describes the cookies and browser storage the site uses. Your organization may also apply its own policies to workspace activity.
Government and third-party sites
The service links to official government websites and may rely on other companies to deliver features. We do not control those sites or their content, and a link may stop working when a publisher changes it.
Availability and changes
The service is under active development. Features, library coverage, source links, and availability may change. Virtus Professional Services LLC may maintain, correct, suspend, or discontinue part of the service. We do not promise uninterrupted access or that every source will always be available through the service.
Suspension and termination
Virtus Professional Services LLC may restrict or suspend access when reasonably necessary to address a security risk, suspected misuse, a legal requirement, or a breach of these terms. Either party may end a paid subscription for a material breach that is not fixed within 30 days of notice. A workspace administrator may remove a member, and you may stop using the service at any time. After a subscription ends, your firm may request an export of its workspace content for 30 days; information is then handled under the Privacy Notice. Sections on your content, fees owed, disclaimers, liability, indemnification, governing law, dispute resolution, and the jury trial and class action waivers continue to apply.
Disclaimers
To the extent permitted by law, the service, source documents, and all output are provided as is and as available, with all faults. Virtus Professional Services LLC disclaims all warranties, express or implied, including merchantability, fitness for a particular purpose, title, and non-infringement.
Virtus Professional Services LLC does not warrant that the service, a search result, generated output, a comparison, or the source collection will be accurate, complete, current, uninterrupted, or error-free. These disclaimers do not exclude rights or warranties that cannot legally be excluded.
Limitation of liability
To the extent permitted by law, Virtus Professional Services LLC and its members, managers, employees, and suppliers will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, goodwill, or data, or for any tax, penalty, interest, or addition to tax, or any claim by your clients, arising from use of or reliance on the service, even if advised of the possibility.
Our total liability for all claims relating to the service is limited to the greater of the fees your firm paid for the service in the 12 months before the event giving rise to the claim, or US$100.
These limits apply whether a claim is decided in arbitration or in court. Some jurisdictions do not allow these limits, so they apply only to the extent permitted.
Indemnification
You and your firm will defend and indemnify Virtus Professional Services LLC and its members, managers, and employees against third-party claims, and related losses and reasonable legal fees, arising from your content, your advice to clients or positions taken in reliance on the service, your misuse of the service, or your violation of these terms or the law.
Governing law and venue
These terms are governed by applicable United States federal law and the laws of the State of Florida, without regard to conflict-of-law rules. The Federal Arbitration Act governs the arbitration agreement in section 21.
Disputes are resolved by arbitration as described in section 21. For any matter that section 21 allows or requires to be decided in court, including small claims, requests for injunctive relief, a claim severed under section 23, and actions to enforce an arbitration award, the state and federal courts located in Florida have exclusive jurisdiction, and both parties consent to that venue. A small claims matter may instead be brought in the small claims court where you live.
Dispute resolution and arbitration
Informal resolution first. Before starting arbitration, the party with a dispute must send a written notice describing it, the relief requested, and contact details. Send notices to us at admin@virtusprofessionalservices.com; we will send notices to the email address on your account. Both parties will try in good faith to resolve the dispute for 30 days after the notice is received. Any deadline for bringing the claim is paused during that period.
Binding individual arbitration. If the dispute is not resolved informally within 30 days, either party may, if needed, start binding individual arbitration. This applies to any dispute, claim, or controversy arising out of or relating to these terms or the service, including their formation, scope, and enforceability, except as stated below. The arbitration will be administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules, or its Consumer Arbitration Rules where the AAA determines they apply, as those rules are in effect when the arbitration starts. The rules are available at adr.org/rules. A single arbitrator will decide the dispute, may award the same individual relief a court could award, and will issue a written decision. Judgment on the award may be entered in any court with jurisdiction.
Where it takes place. The arbitration will take place in the State of Florida unless the parties agree otherwise. It may be conducted by video conference or on written submissions where the AAA rules allow. If the Consumer Arbitration Rules apply, you may choose to have any in-person hearing in the county where you live.
Fees. Filing, administration, and arbitrator fees are paid as the applicable AAA rules provide. Each party pays its own lawyers’ fees and costs unless the arbitrator awards them under applicable law or the AAA rules.
Exceptions. Either party may bring an individual claim in small claims court if it qualifies and stays there. Either party may also ask a court for an injunction or other equitable relief to stop actual or threatened infringement, misappropriation, or misuse of its intellectual property or of the service, including scraping or reverse engineering, without first going through informal resolution or arbitration.
Jury trial waiver
To the extent permitted by law, you and Virtus Professional Services LLC each waive any right to a trial by jury in any dispute arising out of or relating to these terms or the service. If a dispute is decided in court rather than arbitration, a judge, not a jury, will decide it.
Class and representative action waiver
You and Virtus Professional Services LLC may bring claims against each other only on an individual basis, and not as a plaintiff or class member in any class, collective, consolidated, private attorney general, or representative proceeding. Class arbitration is not permitted.
The arbitrator may not combine more than one party’s claims, may not preside over any form of class, collective, or representative proceeding, and may award relief only to the individual party seeking it and only to the extent needed to resolve that party’s individual claim.
If a court decides that this waiver cannot be enforced for a particular claim or request for relief, that claim or request will be separated from the arbitration and decided by a court under section 20, not in class arbitration. It will wait until the individual arbitration is finished. The rest of this section and section 21 still apply.
Changes to these terms
Virtus Professional Services LLC may update these terms when the service or applicable requirements change. The current terms will show their effective date. For a material change, we will give paying firms at least 30 days’ notice. If you do not agree to an updated version, stop using the service; a paying firm may cancel before the change takes effect. A change to sections 21 to 23 does not apply to a dispute that either party had already given notice of before the change took effect.
General
These terms, the Privacy Notice, the Cookie Policy, and any order form are the entire agreement about the service. If a provision is unenforceable, the rest remains in effect, except as section 23 provides for the class and representative action waiver. Not enforcing a provision is not a waiver. You may not assign these terms without our consent; we may assign them to a successor to our business. Neither party is responsible for delays caused by events beyond its reasonable control. You will comply with United States export and sanctions laws when using the service. Legal notices to us must be sent to admin@virtusprofessionalservices.com.
