Who we work with

FIRMS THAT HOLD CONCENTRATED FINANCIAL DATA.

MOSTRO 1040 is built specifically for:

▸CPA firms  — solo practitioners through multi-partner practices that file federal returns and hold non-public personal information for tax, attest, and advisory clients.
▸Accounting firms & bookkeeping practices  — particularly those serving Florida-based small businesses, including those subject to the Florida Information Protection Act (FIPA).
▸Enrolled Agents  — solo and small-firm EAs governed by Circular 230 who renew PTINs and represent clients before the IRS.
▸Tax preparation firms with seasonal staff  — including practices that surge from 5 to 25 people every February through April and need offboarding evidence that holds up later.
▸Bilingual practices serving Spanish-speaking clients  — full service in English and Español, Tampa to Miami and beyond.

Before you call

BRING THE TRUTH, NOT THE PITCH-DECK ANSWERS.

The most useful 30 minutes happen when you arrive ready to answer: Do you actually have a WISP, or did you check the box? How many staff have touched taxpayer data on personal devices? When was the last time you reviewed who has your EFIN credentials? We'll handle it either way — but the honest version saves us both an hour.
