Fylit Pro Terms
Last updated November 9, 2026 (version 2026-11-09). Provided by Vyrtox LLC.
These terms were written with the help of AI software and have not yet been reviewed by a lawyer. They are the terms that apply to Fylit Pro today. If anything in them is unclear, email [email protected] before you rely on it.
1. Who these terms are for
These terms are an agreement between Vyrtox LLC, a Wyoming limited liability company ("Fylit", "we"), and the business that creates a Fylit Pro account ("your firm", "you"). Fylit Pro is offered only to businesses, such as tax practices and company formation services, and not to consumers. By ticking the box at sign-up you confirm that you are at least 16, that you are acting for your firm, and that you are allowed to agree to these terms on its behalf. Our Privacy Policy, at https://fylit.tax/privacy, also applies.
2. What Fylit Pro is
Fylit Pro is software. It lets your firm send a client a link to enter their information, review that information, and fill in the official IRS Form 5472 and pro forma Form 1120 with it, either in your account or through the packet API. Your firm prepares the return and Fylit is the software it uses. Fylit is not a CPA firm, law firm or enrolled agent, does not give tax or legal advice, does not decide what your clients must report, and does not sign, file, fax or mail anything to the IRS. Federal law does treat a company that provides software used to prepare tax returns as a tax return preparer for the confidentiality rules explained in the section on your clients' information. Fylit is not the Internal Revenue Service and is not affiliated with, endorsed by, or sponsored by the IRS or any government agency.
3. Your firm is the preparer
Your firm, not Fylit, is responsible for every return prepared with Fylit Pro. That includes deciding whether a client must file and what to report, checking every value before a packet is signed, completing anything the packet leaves blank, signing, filing on time, and meeting your own professional and legal obligations, including any preparer rules, notices or client consents that apply to your practice, such as written client consent under Treas. Reg. section 301.7216-3 where your use or disclosure of a client's return information needs it. You are responsible for the accuracy of the information you and your clients enter, and for what you tell your clients about it.
4. What the software covers
Fylit Pro supports one situation: a foreign-owned United States single-member LLC that is a disregarded entity filing Form 5472 with a pro forma Form 1120, for the tax years the software offers. It does not cover other entity types, other forms, or every line of Form 5472. Each packet lists what the software did not fill and every value it wrote with where it came from. The IRS can change forms, instructions and deadlines at any time, and the software may not reflect a change yet.
5. Client intake links
An intake link lets whoever holds it enter information for that client, so send it only to your client. Links expire after 30 days, a new link replaces the old one, and you can turn a link off at any time. Your client cannot generate or download a packet; only your firm can.
6. Credits, plans and payment
Prices are shown before you pay and are charged by our payment provider, Stripe, plus any tax that applies. One credit is used each time your firm generates a packet from new or changed information, and each time a live API key returns a packet for a new request. Generating again from the same information, a test API key, and a failed attempt do not use a credit. Credits have no cash value, cannot be transferred, and do not expire while your account is open. A plan renews automatically every month or every year, as shown when you choose it, at the price shown, until you cancel. You can cancel at any time on the Billing page: cancelling stops the next renewal and your firm keeps every credit it already has. Payments are not refundable, except where the law requires a refund, where a packet you paid for could not be produced because of our error, or as the founding member offers below say. We may change prices for future purchases and renewals, and will tell you at least 30 days before a price change affects a renewal.
7. Founding member offers
For a limited time and a limited number of seats we may sell two founding offers. The price, the credits and the number of seats left are shown on the Fylit Pro welcome page before you pay. Founding annual is a yearly Firm plan at the founding price shown. We will not raise that price for the first three renewals after your first payment; after that the price notice in the section above applies. Founding lifetime is one payment. After it, your firm receives the number of packet credits shown when you bought, once a year on the anniversary of the payment, for as long as we offer Fylit Pro. It is not a subscription, it does not renew, and it does not include the packet API. It does not promise any number of packets beyond the credits shown, any particular feature, or any particular tax year. If we stop offering Fylit Pro we will tell you at least 12 months ahead and the yearly credits continue until then. If we sell Fylit Pro, we may transfer these obligations to the buyer. A founding seat belongs to your firm and cannot be transferred or resold. We will refund a founding purchase in full if you email [email protected] at any time until 30 days after packets for tax year 2026 are available in Fylit Pro; we will say on the welcome page when they are. A refund ends the seat and removes any credits from that purchase that your firm has not used. Founding seats are limited, so a refunded seat may be sold again.
8. The packet API
API keys are secret, and your firm is responsible for everything done with its keys. Test keys return samples marked TEST, NOT FOR FILING on every page; do not file them. Live keys require a plan that includes the API. Requests are limited to 60 a minute per key. We do not store the information sent to the API, so keep your own records of what you send. We may suspend a key that is used abusively or that appears to be compromised.
9. Your clients' information
For information about your clients, your firm is the controller and Fylit is your processor or service provider. We use that information only to provide Fylit Pro to your firm, on your instructions, and never for our own purposes, advertising or marketing, and we do not sell it. Section 7216 of the Internal Revenue Code and Treas. Reg. section 301.7216-1(b)(2) treat a company that provides software used to prepare tax returns as a tax return preparer for these confidentiality rules, so we use or disclose a client's tax return information only to provide Fylit Pro to your firm and as those rules allow. Knowingly or recklessly disclosing or using it outside what the law permits is a misdemeanor punishable by a fine and up to one year in prison (section 7216) and carries a civil penalty of $250 per disclosure, up to $10,000 a year (section 6713, higher where section 6713(b) applies). We acknowledge that we have received this written notice of those requirements and penalties, as Treas. Reg. section 301.7216-2(d)(2) contemplates when a preparer discloses return information to a contractor. We keep it confidential, protect it with measures appropriate to the risk, and tell you without undue delay if we learn of a security breach that affects it. We use service providers to host the service, store files, send email and take payments, under obligations that protect the information. When your account closes, or when you ask, we delete your clients' information or return it to you, unless the law requires us to keep something longer. If the law that applies to your firm requires a written data processing agreement, email us and we will put one in place.
10. Acceptable use
Do not use Fylit Pro to break the law, to prepare documents for someone who is not your client, to enter information you are not allowed to share, to interfere with or overload the service, to probe or bypass its security, or to copy or resell the software. We may suspend access that we reasonably believe breaks these rules.
11. Availability and changes
We work to keep Fylit Pro available but do not promise that it will be uninterrupted or error-free. We may change or remove features. If a change materially reduces what your firm has paid for, we will tell you in advance and you may cancel.
12. No warranty
Fylit Pro is provided "as is" and "as available". To the maximum extent the law allows, we make no warranty of any kind, including accuracy, completeness, fitness for a particular purpose, or that any form will be accepted by the IRS. Fylit does not review your returns for accuracy and does not represent your firm or your clients before the IRS.
13. Limitation of liability
To the maximum extent the law allows, Fylit is not liable for any indirect, incidental, consequential, special or punitive damages, for lost profits or clients, or for any penalty, interest, addition to tax or assessment imposed by a tax authority, or the cost of responding to a notice, audit or examination. Fylit's total liability arising out of or relating to Fylit Pro is limited to the fees your firm paid us in the twelve months before the event that gave rise to the claim. These limits do not apply to liability that cannot be limited by law, including for fraud, for gross negligence or willful misconduct, or for death or personal injury caused by negligence.
14. Your firm's indemnity
Your firm will defend and indemnify Vyrtox LLC against claims by third parties, including your clients and any tax authority, arising from returns your firm prepared, signed or filed, from information your firm or its clients entered, from your firm's breach of these terms, or from your firm's professional obligations, except to the extent the claim was caused by our breach of the section on your clients' information.
15. Suspension and ending the agreement
Your firm may stop using Fylit Pro at any time and may cancel a plan as described above. We may suspend or end your firm's access if it does not pay, breaks these terms, or if the law requires it, and we will give notice where we reasonably can. When access ends, download any packets you need first; your client information is then handled as described in the section on your clients' information.
16. Governing Law
These terms are governed by the laws of the State of Wyoming, United States, without regard to its conflict of law rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply. You and Vyrtox LLC agree to the exclusive jurisdiction of the state and federal courts located in Wyoming for any dispute arising out of these terms. Nothing in this section removes any mandatory right you have under the consumer protection law of your country of residence, including any right to bring proceedings in your local courts where that law gives you one.
17. Changes to these terms
We may update these terms. The current version and its date are always on this page. If a change is material, we will email your firm's owner at least 30 days before it applies to your firm, and ask your firm to accept the new version before it continues to use Fylit Pro.
18. General
These terms, the Privacy Policy and the details shown when you buy are the whole agreement about Fylit Pro. If a court finds part of these terms unenforceable, the rest stays in effect. Not enforcing a term is not a waiver of it. Your firm may not transfer this agreement without our consent. We may transfer it to an affiliate or to a buyer or successor of all or part of the Fylit business, and will tell your firm if we do. Notices to your firm go to the owner's email address; notices to us go to [email protected].
