Tax season is brutal. We’re coming to the end of tax season for 2025 and some of us are working down to the wire (unless you ask for an extension! That due date is October 15, 2026). If your firm is running on adrenaline and client deadlines are non-negotiable, any IT failure isn’t just inconvenient, it’s catastrophic. A crashed QuickBooks server at 10 PM on April 14th or other disaster will cost you money and clients. But here’s the thing most CPA firms don’t consider: the best time to fix your IT infrastructure isn’t during tax season, it’s immediately after. Any IT issues that slowed you down this year will slow you down next year too. Take advantage of the natural lull in tax preparation after April 16 and review what broke, fix it before it matters again, implement safeguards while you have breathing room, and document lessons before your team forgets the stress.
Task 1: Audit Your Backup Recovery
Audit your backup recovery for real. Test them. Stress test them! Most firms assume their backups work. Few actually test them. Run a full restore drill on your QuickBooks files, client data, and tax prep software. Verify you meet your recovery time objective—how long until you’re operational. Verify your recovery point objective—how much data would you lose if something were to happen today? Verify offsite redundancy—if the office floods, are your backups safe?
If you can’t restore in under 4 hours, your backup is worthless for tax season emergencies.
Task 2: Update and Patch Everything
Update and patch everything while you can. Tax season isn’t the time for system updates. But after April 15, patch everything: QuickBooks and ProAdvisor software to latest stable versions, Windows servers and workstations with security patches (you should be totally off of Windows 10, by the way), endpoint protection and firewalls with updated definitions, remote access tools including VPNs and remote desktop. Warning: don’t just auto-update and hope. Test QuickBooks updates on a staging server first.
Task 3: Review Your Security
Review and update your security posture. CPA firms are prime ransomware targets because they handle the financial data of hundreds of clients and there is time-pressured urgency during tax season, creating a prime time for when attackers strike.
Make sure your firm has all of the following: multi-factor authentication required for all remote access, email, and cloud apps; review email security quarantine logs; deploy endpoint detection and response (not just antivirus); audit access controls and who has access to what; review password policy. If you’re using the same passwords as last year or if staff share logins, fix this immediately.
Task 4: Evaluate Your QuickBooks Infrastructure
Evaluate your QuickBooks infrastructure. Between QuickBooks Desktop vs. QuickBooks Online vs. Hosted QuickBooks, the decision you made 3 years ago may no longer be right for your firm. Some questions to ask: were you fighting sync issues this tax season? Did remote staff struggle with access? Are you approaching QBO user limits (25 users)? Do compliance requirements mandate on-premises data? The hosted advantage is QuickBooks hosted on a dedicated server means your team gets full desktop functionality with cloud accessibility and your IT provider manages uptime, security, and backups.
Task 5: Document Your Pain Points
Task 5 is documenting your Tax Season 2026 IT pain points. Your team knows exactly what went wrong. Write it down before they forget or leave. Ask your staff: what IT problem frustrated you most this tax season? Where did you lose time to slow systems or workarounds? What worried you about security or data protection? If you could fix one IT thing before next year what would it be? These answers are gold for your IT strategy.
Task 6: Lock In Your 2027 Plan
Task 6 is locking in your 2027 tax season IT support plan now. The firms that survive tax seasons without drama don’t wing it, they plan. Use this end-of-tax season window to review your SLA—does your IT provider guarantee 4-hour response times during tax season? Schedule infrastructure assessments for server health checks and capacity planning. Plan for automation with document management, client portals, and e-signature workflows. Budget for Q3 and Q4 improvements, like upgrading your QuickBooks server or implementing hosted solutions takes 30–60 days.
The Bottom Line
If you don’t plan for next year now, the alternative is another year of fire drills. Most CPA firms don’t do this audit. They either consider IT and security not important enough to focus on or they swear they’ll fix IT after April, then get busy. Come February 2027, CPA firms could be fighting the same problems: slow servers, unreliable backups, frazzled staff, and the existential dread that something critical will break.

FAQ: Post-Tax-Season IT Tasks
Q: When should CPA firms complete post-tax-season IT tasks?
A: Between April 16 and Memorial Day is the best window, after tax season intensity fades but before your team forgets the pain points. This window gives you breathing room to fix issues before they matter again next February.
Q: What’s the most critical post-tax-season IT task?
A: Auditing your backup recovery. Most firms think their backups work but never test them. Run a full restore drill on QuickBooks files, client data, and tax prep software. Verify you can restore in under 4 hours.
Q: Why evaluate QuickBooks infrastructure after tax season?
A: The decision you made 3 years ago may not fit your current firm size. Tax season reveals sync issues, VPN bottlenecks, and user limits. Post-season is the time to switch solutions before next year’s crunch.
Q: How do I document tax season IT pain points?
A: Ask your staff: “What IT problem frustrated you most?” “Where did you lose time?” “What worried you about security?” Capture answers before they forget.
