I started my career road trip as an accountant and tax preparer. Back then there was no such thing as a refund loan from your preparer. We enjoy the same type of client-attorney privilege when it comes to tax matters
That is because your tax information is only between you and the IRS, and any tax preparer or authorized representative you chose to discuss it with. We are sworn to secrecy. They do try to turn CPA's though, holding their CPA accreditation out as some sort of moral reasoning.
