What “good enough” tax software actually costs your firm

Every tax partner and manager who’s pitched a new technology knows the objections before they’re even said out loud: license fees, training hours, and the risk of disruption in a discipline where routine is everything. Those costs are real, and they’re easy to tally on a spreadsheet. What’s harder to visualize is the hidden cost of staying put. 

That’s the comparison firms need to run: not what new software costs against what they’re paying now, but against what a “good enough” workflow actually costs them in hours, errors, staffing, and growth over a multi-year timeline. Let’s break it down.

The hidden costs of outdated tax software for CPA firms 

Sticking with a patchwork of older tools rarely shows up as a single line item. It shows up as time; the one resource that tax firms can’t manipulate during busy season. 

Manual work still eats away most of the day 

The Thomson Reuters Institute’s With recent breakthroughs in leaves plenty of room for the re-entry, review, and error-catching that eats into a preparer’s day. 

Staff feel the squeeze  

A 2025 survey by Distinct Recruitment found that stress and long hours remain a constant feature of busy season, with a pronounced ‘mid-career slump’ among seniors and managers who feel overlooked, despite firms’ efforts to improve work-life balance.  

Talent gaps make it worse 

The Thomson Reuters Institute’s 2026 State of Tax Professionals Report found that a chronic shortage of qualified talent remains the most persistent problem facing tax firms today, with 40% of respondents saying their firm’s capabilities are constrained or at risk because of it.

Why tax firms keep buying capacity instead of building it 

Overworked firms often respond to volume the same way every year: hire seasonal staff to cover the gap. That solves the immediate capacity problem, but it comes with its own costs: 

Recruiting and onboarding temporary staff takes senior time away from client work, right when that time is scarcest 
New seasonal hires are more likely to make errors in unfamiliar, manual-heavy processes

None of these pain points show up on an invoice, but they manifest on a P&L eventually, in the form of overtime, rework, and turnover. 

How do AI and technology solve tax workload issues? 

The State of Tax Professionals Report found that technology adoption and firm profitability move together, and that AI has become the clear front-runner for where firms want to put their investment dollars. 

57% of respondents say AI is now their top investment priority, up from 35% just two years ago 
65% cite greater use of technology as one of the most common tactics for improving profitability 
50% say spending too much time on low-value, low-margin work is their top barrier to profitability

That’s the same mechanism that plays out in any firm running 1040s through disconnected tools: less time moving data, fewer errors to fix later, and more capacity without adding headcount. 

Do the math: a soft ROI calculator for your 1040 tax workflow 

Here’s a simple way to frame it for your own firm. Take the number of 1040s you file, multiply by the average hours per return, and multiply that by your average loaded staff cost per hour. That’s your baseline. But the variables make all the difference. Here are some factors to keep in mind when assessing your efficiency and profitability.  

Manual, poorly integrated workflow 

More re-entry between source documents, prep software, and review tools that don’t talk to each other 
Context switching between disparate programs  
Higher risk of transposition and omission errors that surface during review, or worse, after filing 
Deadlines that depend on manual status checks and follow-up emails 
Senior staff pulled into low-value data entry instead of review and advisory work 
LLMs not integrated with your software that spit out unverified results 
Training and implementation that require a new contact for every standalone program 

AI-powered, single-suite workflow 

Data flows from source documents into the return with far less manual handling 
Fewer handoffs between disconnected tools means fewer places for errors to creep in 
Automated status tracking replaces manual chasing during the busiest weeks of the year 
Preparers and reviewers spend more of their time on judgment calls, not data movement 
Automated document drafting and research is trained on authoritative content and integrated with your internal documentation 
Easy access to support and training from a single, dedicated technology partner 

What does that difference look like in practice? Here are some concrete and anecdotal figures to illustrate:

The payoff: what firms get back with an AI-powered tax suite 

Firms that treat AI as a multi-year strategy (opposed to a one-off tool) are noticing the difference. The Thomson Reuters Institute’s Future of Professionals Report 2026 found that well-planned implementation separates firms that see results from firms that don’t. 

74% of professionals now use AI several times a week 
66% of professionals at firms with a named AI strategy say AI is meeting or exceeding expectations for creating value at work 
Just 22% say the same at firms without an active strategy

That’s the other side of the soft ROI calculator: not just what “good enough” costs you today, but what a connected, automated workflow gives back, in hours, in accuracy, and in the ability to grow revenue without growing headcount.

The verdict: is “good enough” tax software really the safer bet? 

“Good enough” tax software rarely announces its true cost. It arrives quietly, in an extra hour per return, a missed deadline during the busiest week of the year, a senior preparer who burns out and leaves, or a seasonal hire who needs more oversight than the work saved.  

Run the comparison honestly, including the hours, the errors, and the staffing costs on both sides, and the short-term cost of upgrading starts to look a lot smaller than the long-term cost of standing still.
