Get a Free IT AssessmentFor a CPA firm, IT isn’t a back-office function — it’s the production line. Every 1040, every audit, every payroll filing moves through your systems. A single day of downtime during tax season can mean missed IRS deadlines, delayed refunds, and a wave of client calls you can’t get ahead of. And the IRS has been explicit: every tax preparer must now have a Written Information Security Plan (WISP) tied to PTIN renewal, with the FTC’s updated GLBA Safeguards Rule enforceable since 2023.
What that actually requires: hardened security around taxpayer data (IRS Pub 4557, GLBA Safeguards Rule), a documented WISP that matches what’s actually running, software-ecosystem fluency across UltraTax, Lacerte, ProSeries, Drake, CCH ProSystem fx, and QuickBooks (Desktop and Online), secure client portals (SafeSend, SmartVault, Suralink) so returns and source docs don’t travel by email, and IT support that’s actually responsive in Q1 when every minute counts.
IT Services Built for Accounting & CPA Firms
Managed IT for CPA Firms
Predictable monthly cost. Tax-season SLA priorities (Jan–April uptime). Software integration: UltraTax, Lacerte, ProSeries, Drake, CCH ProSystem fx, QuickBooks Desktop, Online, and Enterprise. Print queue and scanner fleet management — CPA firms move serious paper in season and a jammed scanner during a deadline week is a real problem.
IRS WISP & GLBA Safeguards Rule Compliance
The IRS requires a Written Information Security Plan tied to PTIN renewal. The FTC’s updated Safeguards Rule (2023) applies to tax preparers as covered “financial institutions” under GLBA. We build the WISP, implement the technical controls, and document evidence for review. The plan isn’t a one-time deliverable — it has to reflect what’s actually running.
Tax Season Uptime & Surge Support
Production-mode IT from January through April. Onboarding seasonal staff fast with proper access provisioning. Deprovisioning the same day they leave (no shared logins, no lingering access). After-hours support during deadline weeks. Backup systems tested before season, not during it.
Secure Client Portals & Document Exchange
Tax returns, W-2s, K-1s, financial statements — none of this should travel by email. Setup and management of SafeSend, SmartVault, Suralink, and ShareFile. Client-side training so they actually use the portal instead of emailing a screenshot of a 1099.
Cybersecurity for CPAs
Tax-season phishing surges (IRS impersonation, e-file rejection scams, refund-stealing schemes). MFA on all preparer accounts. EDR/MDR for ransomware (CPAs are repeatedly named in ransomware targeting reports because of the value of the data and the time pressure during filing season). Incident response that includes IRS notification protocols.
Backup, Continuity & Multi-State Filing
Immutable backups for all tax-year working files. Multi-state filing data segregation for firms preparing returns in multiple states. Disaster recovery tested before tax season. Record retention configured to NY Tax Law §658 and IRS Pub 4557 requirements (typically 7 years for tax records, with longer periods for certain documents).

Frequently Asked Questions
Do you build the IRS-required Written Information Security Plan (WISP)?
Yes — and not as a one-page template. The WISP has to describe what’s actually running in your firm: who has access to what, how taxpayer data is encrypted, what your incident response process is, how you train staff, and how you vet third parties. We build it from your real environment, implement the technical controls it references, and keep it updated as things change — because an outdated WISP that doesn’t reflect reality is worse than none at all if the FTC asks.
What accounting and tax software do you support?
The systems CPA firms actually use: Thomson Reuters CS Suite (UltraTax, Practice CS, FileCabinet CS), Intuit Lacerte and ProSeries, Drake, CCH ProSystem fx and Axcess, QuickBooks Desktop, QuickBooks Online, QuickBooks Enterprise, Xero, Sage Intacct, and NetSuite. For document exchange: SafeSend, SmartVault, Suralink, ShareFile. We’ve handled installs, migrations, and tax-season tuning across these.
How do you handle tax season uptime priorities?
Tax season is treated as a different operational mode. Pre-season hardening starts in November: backup tests, capacity checks, software updates on a controlled schedule, staff access reviews. From January through April, change windows are restricted, backups verify daily not weekly, and the help desk has dedicated CPA-aware staff. Deadline weeks (March 15, April 15, extensions) get explicit priority handling.
How quickly can you onboard or offboard seasonal staff?
Same-day provisioning when properly scheduled. Each seasonal hire gets a documented onboarding: account creation, MFA enrollment, software access scoped to their role (preparer vs. reviewer vs. partner), portal access if needed, and an offboarding date set at the start. Deprovisioning happens the day they leave — no lingering access, no shared logins, no accounts left active “just in case.” This matters for WISP compliance.
What does managed IT cost for a NYC CPA firm?
It varies by firm size, software stack, and on-site presence needs. We have a detailed breakdown in our managed IT pricing guide with per-user ranges and what’s included at each tier. The short version: CPA firms typically sit in the mid range, with tax-season surge support and WISP compliance work sometimes scoped separately depending on firm size and current state.
