AI tax software is changing how firms manage busy season. But not all systems are built the same — some automate basic data entry, while others scale across complex returns, multi-entity clients, and ever-shifting regulations.
For partners evaluating their first AI tool, the key is asking the right questions before signing a contract. The goal isn’t to buy software — it’s to buy back time, accuracy, and control. Here’s where to start.

Does the AI handle complex returns and updated regulations?
AI tax prep software must do more than process simple W-2s. Complex returns like multi-entity, multi-state, international, or industry-specific returns are where most systems break down.
Basic tools can’t manage partnerships, real estate portfolios, or corporate schedules. Advanced systems can. The difference is how they interpret context, not just forms.
Tax laws also change constantly. When the IRS or state regulators roll out new rules, the software should apply those updates across every return automatically — not three weeks later after you’ve already filed.
Ask vendors:
- How fast do you update for new tax laws?
- What types of returns can your system handle?
- How does your AI manage unusual or edge-case filings?
Real-world takeaway: A system that chokes on complex returns might save time in January but collapse in March when deadlines close in.
Will it integrate with your current tax workflow?
If a platform doesn’t fit your workflow, it creates new friction instead of removing it. The best AI tools plug directly into the systems you already use.
Choose integration depth based on your team’s tech comfort. Tech-savvy staff can handle API-level automation. Smaller teams might prefer simpler imports to start.
Ask:
- Does this system integrate with our current software?
- Will it connect to our document portal and CRM?
- How much manual cleanup remains after the AI runs?
Time-saving tip: The best systems integrate with document management so your team never uploads the same file twice.
Are we getting real ROI and fair pricing?
AI pricing varies wildly from per-return models to flat-rate subscriptions. What matters is your ROI: how much time, money, and capacity you get back.
Common pricing models include:
- Per return: Pay for each completed filing.
- Subscription: Fixed monthly/annual fee.
- Tiered: Based on client volume or firm size.
To calculate ROI:
- Measure the time saved per return.
- Multiply by your hourly billing rate.
- Subtract software cost and training time.
Example: A $75/hour staff member saving 2 hours per return across 500 returns equals $75,000 in labor saved. If your AI costs $25K annually, that’s a 200% ROI in one season.
Also consider:
- Increased client capacity
- Fewer review errors
- Reduced overtime costs
- More time for advisory work
Hidden costs to flag:
- Implementation fees
- Training time
- Support and update costs
What kind of support and data security compliance are offered?
Tax data is the definition of sensitive, and hackers know it. Security isn’t a just feature – it’s table stakes.
Every vendor should provide:
- End-to-end encryption (in transit and at rest)
- Multi-factor authentication
- SOC 2 Type II certification
- Regular security audits
- IRS Pub 4557 compliance
Just as important is support. During busy season, a 24-hour response window isn’t good enough.
Expect:
- Live chat or phone support during peak months
- Clear onboarding and training materials
- Regular status updates and maintenance alerts
Red flag: If a vendor can’t tell you where your data is stored or how it’s protected, walk away. Transparency equals trust.
How trustworthy and proven is the vendor?
AI has created a flood of new software vendors. Some are solid, some are short-lived. Before betting your workflow on one, verify their experience and stability.
Check for:
- Tax-specific expertise: How many CPAs or tax pros are on their dev team?
- Case studies: Ask for results from firms like yours — hours saved, error rates reduced, capacity gained.
- Financial stability: New vendors can vanish. Confirm their funding and track record.
Partner tip: Always ask for references from firms that have used the system for at least two tax seasons. First-year data is rarely the full picture.
Testing the AI with real scenarios
Before fully committing to an AI tax solution, test it with real-world scenarios. Hands-on evaluation reveals capabilities and limitations that sales demonstrations might miss.
Before committing, test the system with real client data. Sales demos hide limitations.
Try these test cases:
1. A complex business return
Process a return with multiple income streams, depreciation schedules, and business deductions. Check if the AI correctly categorizes expenses and applies tax rules.
2. A multi-state return
Test a return with income from several states. The AI should correctly allocate income and apply different state rules for deductions and credits.
3. An unusual situation
Process a return with a one-time event like a property sale, divorce, or business acquisition. These edge cases often reveal an AI system's flexibility.
Compare results to your manual returns. Score each on accuracy, speed, and ease of correction.
Testing strategy: Create a scoring system for each test case, rating factors like accuracy, time saved, and ease of correction. A structured test gives you more than a gut feeling — it gives you data to defend your investment.
Why the right AI software helps partners reclaim high-value work

The right AI doesn’t replace your team — it gives them time to do real work. With Filed, partners move from review bottlenecks to revenue-driving strategy.
Firms see:
- 30–50% reduction in prep time per return
- 25–40% increase in seasonal capacity
- Higher retention and morale from reduced burnout
As one partner put it:
“Before AI, I spent 70% of my time reviewing returns. Now it’s 30% — and the rest goes to client meetings and strategic planning.”
