It means that documents tied to your profile are secured under your username and password. Only you and your Pro will have access to your documents. In the event that a question is raised to the Taxfyle team and requires a review of your account, a designated in-house Taxfyle representative may also review your relevant documents. All parties are held to stringent confidentiality standards. Should you use Taxfyle again next year, your Pro will be able to refer to your prior year documentation when preparing the current year. This will allow the completion of subsequent years to be expedited as you won't have to upload files that you uploaded in years prior.
