Nobody approves a budget line called technical debt. Nevertheless, it accumulates 20 minutes at a time: a manager reconciling two reports, an associate re-entering client data and an IT leader preserving a fragile integration because replacing it would disrupt busy season. Each workaround seems manageable on its own, which is exactly why it can remain in place for years.
Over time, those small compromises start shaping how the firm operates. Staff build processes around system limitations, critical knowledge becomes concentrated with a few people and new initiatives require more effort than expected because the underlying environment was never designed to support them. The technology may still function, but the firm is spending more time, money and attention to keep it functioning.
That is the real cost of technical debt. It is not simply an aging server or an outdated application. It is the accumulated burden of decisions that once solved an immediate problem but now create recurring labor, maintenance, risk and delay. Much of that cost never appears in the IT budget. It shows up in write-downs, slower review cycles, support escalations and growth plans that are harder to execute than they should be.
What CPA Firms Are Really Carrying
Technical debt can begin with a reasonable decision. A firm customizes an application to meet an immediate need, adds a point solution to solve a workflow problem or postpones an upgrade until after busy season. The trouble starts when the temporary fix becomes part of the operating model and every future change has to work around it. This pattern is especially common when firms keep adding point solutions to address immediate needs without considering how each one fits into the broader technology environment.
McKinsey describes the “interest” on technical debt as the “complexity created by fragile integrations, nonstandard data and workarounds needed to meet business requirements.” Inside a CPA firm, that interest may look like exports that must be cleaned before use, multiple applications holding different versions of client information and/or review steps added because teams do not fully trust the data. None of those issues stops the work, but each makes the next return, report, hire or acquisition harder to absorb.
The Cost Moves Out of IT
The most visible expense may be an aging application, overlapping subscription or escalating support agreement. The larger burden often sits with the people using the environment every day. Technical debt can quietly consume staff capacity through:
- Re-entering information that does not move cleanly between systems
- Reconciling reports before the data can be reviewed or trusted
- Searching across email, shared drives and applications for current information
- Resolving recurring exceptions that should no longer require manual intervention
- Pulling managers into process questions that should not require their attention
According to Thomson Reuters, 50% of tax, audit and accounting respondents said they spend too much time on low-value, low-margin work, making it the leading barrier to stronger profitability. Technical debt does not account for all of that lost capacity, but it contributes whenever system limitations turn professionals into the connection between tools. The cost then appears as overtime, write-downs, slower turnaround and less time available for client service or higher-value work.
A firm may view the current environment as less expensive because replacement would require a visible investment, even while it continues paying for consultant hours, emergency fixes, redundant licenses and delayed projects. Research estimates that technical debt can account for 21% to 40% of organizational IT spending, while also creating indirect costs through slower execution and underused technology.
The Environment Becomes Harder to Govern
As systems, vendors and exceptions multiply, maintaining consistent controls becomes more difficult. User access may be managed differently across applications, temporary permissions can become permanent and documentation may no longer reflect how information moves through the firm.
IRS Publication 5708 calls for tax and accounting firms to assess risk, inventory hardware, document authorized access, oversee service providers and regularly update safeguards as business operations change.
The FTC Safeguards Rule reinforces many of the same expectations for covered financial institutions, including tax preparation firms. Fragmentation does not automatically mean a firm is noncompliant. It does mean that proving who has access, which controls are enforced and whether documentation is current requires more effort. A cyber insurance renewal, client review or incident response exercise can expose that burden quickly.
Technical Debt Can Block What Comes Next
The consequences become harder to dismiss when the firm tries to automate a workflow, deploy AI or integrate an acquisition. These initiatives depend on usable data, consistent permissions, documented processes and systems that can exchange information without adding more manual handling.
CPA.com’s 2025 AI in Accounting Report notes that legacy systems are straining under new expectations as firms rethink workflows, services and decision structures around AI.
A firm can purchase AI tools without resolving technical debt, but fragmented data and weak integrations make it harder to move from isolated experiments to repeatable firmwide use. What appears to be an AI adoption problem may actually reflect years of inconsistent data practices, application decisions and access models.
Mergers create another challenge because they force firms to reconcile systems, identities, workflows and security practices on a deadline. Research finds that systems and process integration commonly rank among the most difficult parts of M&A, while successful integrators were 57% more likely to fully integrate those areas.
For a growing CPA firm, technical debt becomes an integration tax. Duplicate platforms remain longer, staff maintain parallel processes and expected benefits take more time to reach. The same constraint can affect organic growth, with firms that have highly integrated technology stacks 53% more likely to report high growth.
Why Firms Often Recognize It Too Late
Technical debt rarely becomes urgent while the environment is operating under normal conditions. It surfaces when the firm asks the environment to do something different, such as supporting busy season volume, onboarding a large group, completing a security review or moving an AI pilot into production.
Those events do not create the problem. They expose dependencies that were easier to tolerate when the firm was smaller, less integrated or moving at a slower pace. By then, leadership may have fewer options, less time to respond and more pressure to accept another temporary solution. Busy season is one of the clearest examples because it exposes where data, workflows and institutional knowledge depend too heavily on manual coordination.
Deciding What Deserves Attention First
The answer is not to replace every older system or launch a sweeping overhaul. Some technical debt is intentional and economically reasonable, particularly when a platform remains secure, supported and aligned with the firm’s needs. The priority is understanding where the firm is paying the highest ongoing cost.
Start with recurring problems rather than an inventory of everything that is old. For each issue, ask:
- How frequently does it occur?
- How much staff time does it consume?
- Does it create security or compliance exposure?
- Does the process depend heavily on one person’s knowledge?
- Does it limit growth, automation, onboarding or integration?
- Will postponing the fix make it more expensive or disruptive?
That assessment helps distinguish manageable inconvenience from recurring operating cost, material risk and strategic constraint. A monthly spreadsheet workaround may not deserve the same response as an unsupported system holding sensitive data, but it should not remain invisible simply because staff have become skilled at compensating for it.
The Goal Is Not Zero Technical Debt
Every firm will carry some technical debt, just as every business makes tradeoffs between immediate priorities and longer-term improvement. The objective is to make those tradeoffs visible enough that leadership can decide what to maintain, remediate, consolidate or retire.
A useful starting point is one workflow that repeatedly consumes time or requires exceptions. Trace where the work slows down, which systems are involved and what people do to keep it moving. That exercise often reveals a cost the firm has been paying for years, 20 minutes at a time.
