Who is this course for?

This advanced program is designed for experienced Payroll, HR, and finance professionals who already understand U.S. payroll fundamentals and now require deeper expertise in highly complex areas of payroll taxation, equity, fringe benefits, deferred compensation, and organisational change events. It is also ideal for those overseeing outsourced payroll vendors and seeking to strengthen their ability to review, audit, and ensure compliance in specialised and high-risk payroll scenarios.

What will you achieve?

Upon completing this course, participants will gain the confidence and technical mastery needed to navigate the most intricate aspects of U.S. payroll. You will develop a deeper understanding of advanced gross-to-net calculations, multilayer tax reporting obligations, specialised benefit taxation, complex timing rules for income inclusion, and compliance
risks tied to executive and equity compensation. You will also learn how organizational changes, such as mergers, acquisitions, and workforce transitions, impact federal, state, and local payroll requirements.
