The payroll tax management overhaul that saved Equifax six figures
Managing payroll taxes for a global enterprise is never simple. For Equifax, the stakes were especially high. When they moved to Workday in 2012, they needed a partner who could handle payroll tax management at scale: one with deep Workday expertise, full data transparency, and the ability to navigate the kind of multi-entity, multi-jurisdiction complexity that most providers aren’t built for.
They found that in OneSource Virtual (OSV).

As a Workday-exclusive provider of payroll tax services, OSV operates directly alongside Equifax’s Workday environment, while giving their team full visibility into their own data without the reconciliation or extra fees that plagued their previous provider. For Karen Skelton, Equifax’s payroll and employment tax leader, that access was a deciding factor.
The early days of the partnership weren’t without hiccups. But OSV’s willingness to listen, course-correct, and show up for their customers proved just as important as the technology itself. What followed was a turnaround that Karen describes as a 180-degree shift — and the numbers back it up.
Equifax's payroll tax costs with OSV run 30–40% below what they paid for their previous vendor. By outsourcing payroll tax filing, remittance, and compliance management to OSV rather than building the function in-house, they're saving an estimated $130k – $140k annually in staffing and software costs alone. Open support tickets dropped by nearly 80% from year one to year two. And with OSV's payroll tax reporting tools, Skelton's team can reconcile tax data against Workday in minutes — not hours.
For organizations looking to strengthen Workday payroll tax compliance at scale, the Equifax story is a clear illustration of what the right partner can deliver.
