2026 Accounting Technology Benchmark Report (below $5M)

Best Professional Tax Software for Accounting Firms Under $5 Million

Executive Summary

There is no single "best" tax software for firms under $5 million. The optimal choice changes dramatically as firms grow because cost becomes a smaller percentage of revenue while efficiency, diagnostics, workflow, and scalability become increasingly important.

A solo CPA can save thousands of dollars annually with Drake, while a $4 million firm may generate far greater returns by investing in UltraTax CS or CCH Axcess Tax due to improved staff productivity and support for more complex engagements. Market share data also reflects this pattern: Drake and ProSeries are strongest among sole practitioners, while UltraTax CS and CCH Axcess gain share as firm size increases.

Bottom Line

For firms under approximately $2 million in annual revenue, Drake Tax offers the strongest combination of affordability, speed, support, and return on investment. As firms grow into the $2–5 million range, the value equation shifts: partner time becomes more expensive, return complexity increases, and workflow efficiency often matters more than licensing costs. At that point, UltraTax CS becomes the leading choice for many firms, while CCH Axcess Tax is best reserved for firms building toward a larger, enterprise-scale practice.

Overall Rankings by Firm Size

Segment 1: Startup Firms (<$250K)

Recommended: Drake Pay-Per-Return

Overall Score: 9.8

When a firm prepares fewer than 100 returns, paying for an enterprise platform rarely makes financial sense.

Advantages

• Minimal upfront investment
• Low fixed costs
• Excellent support
• Upgrade path as the firm grows

A pay-per-return model allows new firms to preserve cash while still using professional-grade software. Drake's pricing structure is designed specifically for firms with unpredictable or low return volumes.

Segment 2: Firms Under $500,000

Winner: Drake Tax

Score: 9.7

At this stage, owners are focused on:

• Profitability
• Minimizing overhead
• Preparing returns quickly
• Excellent customer support

Drake continues to dominate because the cost difference versus premium platforms can represent a meaningful percentage of annual profit.

Why Drake Wins

• Lowest ownership cost
• Unlimited returns available
• Outstanding technical support
• Fast data entry
• High productivity

Segment 3: Firms Between $500K and $1 Million

Winner: Drake Tax

Score: 9.5

These firms generally employ:

• 3–8 employees
• 600–1,200 returns annually
• growing business-return volume

Decision Factors

• Software cost
• Speed
• Staff training
• Diagnostics

Many firms remain with Drake because the savings can fund other growth investments such as marketing, hiring, or client experience improvements.

Segment 4: Firms Between $1 Million and $2 Million

Winner: Drake Tax (Narrow Margin)

As firms approach $2 million, complexity often increases:

• Partnerships
• Multi-state returns
• S-corporations
• Trusts
• Advisory services

Why Drake Still Leads

The cost advantage remains significant, but this is also the point where firms should evaluate whether the additional diagnostics and workflow capabilities of UltraTax CS justify the higher investment.

Segment 5: Firms Between $2 Million and $3 Million

Winner: UltraTax CS

Score: 9.5

This is often the "tipping point."

Typical characteristics:

• 12–20 professionals
• Multiple reviewers
• Increasing advisory work
• More sophisticated tax planning

Why Firms Switch

• Superior diagnostics
• Better review tools
• Stronger multi-state capabilities
• Integration with the Thomson Reuters ecosystem
• Improved scalability

Although the annual investment is higher, many firms find that increased staff efficiency offsets the additional software cost.

Segment 6: Firms Between $3 Million and $5 Million

Winner: UltraTax CS

Score: 9.6

At this level, partners increasingly prioritize:

• Staff efficiency
• Review workflow
• Integration
• Automation
• Client complexity

Software cost becomes a much smaller percentage of firm revenue.

Typical Technology Stack

• UltraTax CS
• Practice management platform
• Document management
• Client portal
• Workflow automation

For firms expecting continued growth beyond $5 million, CCH Axcess Tax becomes an increasingly compelling alternative due to its enterprise architecture and scalability, despite higher implementation and licensing costs.
