What FinishTax Is
FinishTax is a practice-management platform for tax preparers, operated by OSO Corp, doing business as FinishTax ("FinishTax," "we," "us"). It helps you organize clients, collect and store documents, manage tasks and deadlines, send invoices and accept payments, communicate with clients through a secure portal, and send documents for legally binding electronic signature with identity verification. Your working data, on every plan including free, is stored in our encrypted cloud infrastructure — there is no local-only mode.
FinishTax is not a tax-calculation or e-filing service. It does not compute tax liability, prepare or generate completed tax returns, or transmit returns to the IRS or any government body. You, the tax professional, remain solely responsible for the accuracy of your work and for compliance with all applicable laws and IRS requirements, including the proper use of Form 8879 e-signature authorizations.
Your Account (Paid Plans)
To use a paid plan, you must:
- Be at least 18 years old
- Provide a valid email address
- Keep your login credentials secure and confidential
- Maintain one account per person — shared logins are not permitted
You are responsible for all activity that occurs under your account. If you suspect unauthorized access, contact us immediately at contact@finish.tax.
Acceptable Use
FinishTax is intended for tax preparation workflow management. You agree not to:
- Upload illegal, harmful, or malicious content
- Use the service to distribute malware or conduct phishing
- Attempt to reverse engineer, decompile, or extract the source code
- Circumvent any access controls or security features
- Use automated tools to scrape, crawl, or overload the service
- Resell access to the service without written permission
Your Data
You own your data entirely. We claim no rights to your client information, tasks, documents, files, or any other content you create in FinishTax.
On every plan, including free, your data is stored in our cloud infrastructure and is accessible only through your authenticated account. Social Security Numbers, IRS preparer credentials, and connected-account tokens are encrypted by FinishTax with AES-256-GCM before they reach the database. We do not sell your data or use it for advertising. We share it only with the service providers needed to run FinishTax, as described in our Privacy Policy.
You can export all of your data at any time using Settings → Your data → Download your data.
Electronic Signatures & Identity Verification
FinishTax includes electronic signature features, including for IRS Form 8879. By using these features, you and your clients consent to do business electronically and to the use of electronic records and signatures, which have the same legal effect as handwritten signatures under the federal ESIGN Act and applicable state UETA laws.
- You may request a paper copy of any signed record, and may withdraw consent to electronic records, by contacting contact@finish.tax (withdrawing consent may prevent use of the e-signature features).
- To sign electronically you need a current web browser, an internet connection, and the ability to receive email.
- Signer identity may be verified through our provider Stripe Identity using a government-issued photo ID and a live selfie before signing.
- As the preparer, you are responsible for confirming that electronic signing is appropriate for a given document and for retaining signed records as required.
Payments and Refunds
Free trial. Every paid plan includes a 7-day free trial, once per firm. A payment method is required to start the trial, but nothing is charged during it. The first charge is made on day 8, at the price of the plan you selected, unless you cancel before then; cancelling during the trial costs nothing. A complimentary plan or an earlier free trial counts as the firm's trial. Free trials without a card that were started before October 30, 2026 run to their end. You may instead subscribe without a trial and be charged when you subscribe. Your plan renews automatically every month or year, as you chose, until you cancel it in Plan & Billing. Purchases in our iPhone or iPad app follow Apple's terms.
For plans started on our website:
- Paid plans are billed monthly or annually through Stripe
- You may cancel your subscription at any time from Settings → Billing
- Cancellation takes effect at the end of your current billing period — no partial-period refunds
- If we increase prices, existing subscribers will receive at least 30 days written notice before the new price takes effect. Founding-firm subscriptions are excluded: their price is fixed for the life of the subscription
- Annual subscriptions that are cancelled receive access through the end of the paid year
Subscriptions bought in the iOS app. If you subscribe in the FinishTax app on iPhone or iPad, the subscription is sold through the App Store and billed to your Apple ID, not through Stripe. Payment is charged to your Apple ID when you confirm the purchase. The subscription renews automatically each month or year, at the price shown in the app, unless you turn off auto-renew at least 24 hours before the current period ends; the renewal is charged within the 24 hours before the period ends. You can manage or cancel it at any time in your device's Settings → your name → Subscriptions, or with Manage subscription on the app's Billing screen. Cancelling takes effect at the end of the period you have already paid for. Refunds for App Store purchases are handled by Apple under Apple's policies, at reportaproblem.apple.com. App Store prices and price changes are handled by Apple. Deleting your account doesn't cancel a subscription bought in the app on iPhone or iPad — cancel it first in Settings → your name → Subscriptions.
Referral Credits
- A firm owner can share a referral link. A firm that signs up through it on our website can start the same 7-day free trial as any other firm
- When the referred firm pays its first paid invoice and still has an active paid subscription 14 days later, the referrer receives an account credit worth 50% of one month of the referrer's plan at its monthly list price. A referrer on the Free plan receives 50% of the Solo plan's monthly price
- One credit per referred firm, and at most 12 credits per referrer in any 12 months. Team-member accounts and firms that never pay don't earn credits
- Credits are applied to your FinishTax account balance and come off future invoices. They have no cash value and can't be transferred
- We may withhold or reverse credits earned through self-referral, fake accounts or other abuse, and we may change or end the program with notice; credits already applied stay on your account
Availability and Reliability
- Free plan: Provided as-is with no uptime guarantee
- Paid plans: We target 99.5% uptime for cloud-synced features. Scheduled maintenance windows will be communicated in advance when possible
We keep encrypted nightly backups of the service for disaster recovery. The Download your data feature exists to give you a portable copy of your own records, and we recommend keeping one.
Limitation of Liability
FinishTax is a workflow management tool. We are not liable for:
- Missed tax deadlines or filing errors
- Professional errors or omissions in your tax preparation work
- Any consequences arising from decisions made based on information organized in FinishTax
To the maximum extent permitted by law, our total liability is limited to the amount you paid for the service in the 3 months preceding the event giving rise to the claim.
Termination
- We may suspend or terminate accounts that violate these terms, with notice when reasonably possible
- Canceling a paid subscription does not delete your data — it downgrades your account to the free plan, and your data is retained until you delete it
- You may delete your account and data at any time from Settings → Your data → Reset or close your account → Delete account on the web (firm owners), in the FinishTax app from More → Settings → Your data → Reset or close your account → Delete account (team members: More → Settings → Delete account, at the bottom), or by emailing privacy@finish.tax to request deletion. Deleting your account doesn't cancel a subscription bought in the app on iPhone or iPad — cancel it first in Settings → your name → Subscriptions.
Governing Law
These terms are governed by the laws of the United States. Any disputes arising from these terms or your use of FinishTax will be resolved by binding arbitration in accordance with the rules of the American Arbitration Association.
