Terms of Service

Last updated: September 8, 2026

Plain-language summary: TaxStash is an estimation tool, not a tax preparer or advisor. We never touch your bank account or file anything on your behalf. Paid plans are billed through Stripe; you can cancel a subscription anytime. This isn't a substitute for reading the full terms below.

1. What TaxStash is

TaxStash is a self-employment tax estimation tool. It calculates approximate quarterly tax obligations based on income and expense data you enter yourself. It does not access your bank accounts, does not file tax returns, and does not submit anything to the IRS or any state tax authority on your behalf.

2. Not tax, legal, or financial advice

Every number TaxStash shows you is an estimate based on simplified assumptions about federal tax law. It does not account for every deduction, credit, filing scenario, or state-specific rule that could apply to you. Nothing in this app constitutes tax, legal, accounting, or financial advice. Confirm any number here with a licensed CPA or tax professional before filing or making a payment based on it.

3. Accounts

You need an account (email and password) to use the income-tracking features of TaxStash. You're responsible for keeping your login credentials secure and for all activity under your account. Let us know if you believe your account has been accessed without your permission.

4. Plans, billing, and cancellation

Free plan — no cost, no card required, calculator-only.
21-day trial — new accounts get full access to every feature for 21 days automatically. No card is required to start a trial, and you won't be charged when it ends unless you separately choose a paid plan.
Token pack — a one-time, non-recurring purchase. It is not a subscription and does not auto-renew.
Monthly / Annual subscriptions — recurring charges billed through Stripe until canceled. You can cancel anytime; cancellation takes effect at the end of the current billing period, and you keep access until then.

All payments are processed by Stripe. We never see or store your full card number — Stripe handles that directly. Refunds are handled on a case-by-case basis; contact us if something went wrong with a charge.

5. Your data

You own the income, expense, and calculation data you enter. You can export it as a CSV at any time from within the app, and you can permanently delete it using the "Delete all data" option in your account settings. See the Privacy Policy for how we handle it.

6. Acceptable use

Don't attempt to interfere with, disrupt, or gain unauthorized access to TaxStash's systems or other users' accounts or data. Don't use the service for anything unlawful.

7. No warranty, limitation of liability

TaxStash is provided "as is," without warranty of any kind. We do our best to keep the tax figures accurate and current, but tax law changes and every situation is different — we're not liable for penalties, interest, or other consequences arising from reliance on an estimate shown in this app.

8. Termination

You can stop using TaxStash and delete your account at any time. We may suspend or terminate access for violations of these terms.

9. Changes to these terms

We may update these terms as the product changes. Material changes will be reflected by updating the date at the top of this page.
