Enterprise-sized businesses spend an average of 28 percent of their software budgets on upgrades, migrations, and licensing changes they view as unnecessary, according to a survey of 2,018 IT leaders at companies with at least 10,000 employees and over $1 billion in annual revenue.

The report, titled "The Software Tax" and conducted by research firm Censuswide on behalf of Origina, a software maintenance provider, reveals the depth of vendor lock-in constraining large organizations. About half the respondents were U.S.-based; the remainder were in the United Kingdom.

The dynamics are stark: 76 percent of IT leaders say their organizations have minimal negotiating leverage with major software vendors, and 80 percent agree that switching away from primary vendors would cause significant operational disruption. Most enterprises view these forced changes as harmful—a substantial majority confirmed their organizations paid for vendor-driven modifications in the last three years they expected to degrade performance, reliability, or business value.

The opportunity cost is real. When IT budgets are consumed by mandatory maintenance cycles, funding dries up elsewhere: 36 percent of respondents cited innovation as impacted, 32 percent noted headcount constraints, 31 percent identified security, and 31 percent pointed to customer-facing investments.

James McGlennon, former global executive vice president and CIO at Liberty Mutual, described the technical capacity drain. An upgrade cycle, he said, can occupy top technical workers for "the better part of a year"—a recurring tax on the engineering resources that differentiate a business in competitive markets.

Tomás O'Leary, CEO and founder of Origina, said the market dynamic leaves technology leaders with constrained options. "Companies accept unwanted changes to maintain support for essential systems," he said. "The result is costs that hollow out budgets, consume engineering time, and starve unfunded innovation."

The political appetite for intervention is evident: 91 percent of surveyed IT leaders would support laws providing enterprises with protections similar to those afforded long-term residential tenants. Only 1 percent opposed such measures.
