Why does a free review need my tax return at all?
Because the real opportunities are in the details. Your return shows your income sources, your marginal rate, what you're already deducting, and what you're missing. A review built on a questionnaire can only guess. A review built on your return can calculate.
How do I send my return to Gambit?
Through our secure upload portal at gambit.tax/tax-opportunity-report. Never by email. Email is not a safe way to send a tax return to anyone, including us.
Where is my return stored?
We store your documents with Box, the same platform used by Fortune 500 companies. Box maintains SOC 2 Type II and ISO 27001 certifications. Box enforces strict access controls and is independently audited on a regular basis.
Who can see my return?
Only the Gambit team members preparing your report can open your documents.
What rules do tax firms have to follow to protect my data?
Professional tax preparers are treated as financial institutions under federal law, which means:
The FTC Safeguards Rule requires them to run an information security program that protects customer data. Source: FTC
The IRS expects every professional preparer to maintain a written information security plan (WISP). Source: IRS Publication 5708
The Gramm-Leach-Bliley Act (GLBA) requires a privacy notice explaining how your information is used. Read Gambit's GLBA notice.
What happens to my return if I don't become a client?
[PLACEHOLDER: retention and deletion policy for non-clients.] Either way, we don't sell your information. [VERIFY against privacy policy] See our Privacy Policy for details.
What should I ask any tax firm before I upload my return?
Whether you work with us or someone else, get clear answers to these six questions first:
How do I send documents? The answer should be a secure portal, never email.
Where are my files stored, and with which provider? A firm should name it.
Who can open my return? Access should be limited to the people doing the work.
Do you have a written information security plan? Every professional preparer is expected to.
Where is your privacy notice? It should be easy to find on their website.
What happens to my documents if I don't hire you? You should know how long they're kept and how to have them deleted.

You upload through a secure portal, and your documents are stored with Box, a platform used by Fortune 500 companies and healthcare organizations, with strict access controls and regular independent audits.
Are tax preparers required to protect my information?
Yes. Under federal law, professional tax preparers must maintain an information security program under the FTC Safeguards Rule, and the IRS expects every preparer to keep a written information security plan.
Does Gambit sell my data?
