How Jazz Pharmaceuticals cut open payroll tax cases by 92%

Running payroll for 1,800+ employees with a two-person team means every hour counts. See how Jazz partnered with OSV to tighten payroll tax compliance and free up time for strategic work.

“I know I can count on OSV as a partner because we both view our working relationship as teamwork. And if you view the working relationship as a team, it almost always guarantees success.”

A partnership built on accuracy, scalability, and shared accountability

When Jazz Pharmaceuticals set out to replace a payroll provider producing frequent reporting errors and missing W2s, they were past the point of needing a new vendor. What they needed was payroll and tax services that could support a global biopharmaceutical company with 1,800+ employees, while freeing their two-person internal payroll team to focus on strategic priorities.

Jazz chose Workday for the technology and OneSource Virtual (OSV) for the service layer built natively inside it. OSV's Workday-native approach supports payroll automation and payroll process optimization across U.S. jurisdictions, with a dedicated customer success manager keeping open cases moving and experts owning payroll tax filing and payroll tax compliance.

The partnership has led to more than a 92% drop in outstanding payroll tax cases in a single year, and 90% of Jazz employees now receive their bi-weekly pay via direct deposit, with the accuracy and scalability their team demands.
