Payroll Tax Compliance for Healthcare

Payroll tax is a state-based tax levied on wages paid by employers. For medical practices, determining payroll tax liability can be complex due to the various engagement models used for medical practitioners, including tenant doctor arrangements, contractor agreements, and employment.

Increased Audit Activity

State Revenue Offices have significantly increased their audit focus on medical practices. Recent cases have resulted in assessments exceeding $250,000 plus penalties and interest.

Key Compliance Factors

Relevant Contracts

Payments under employment-like contracts may attract payroll tax. The substance of the relationship, not just its label, determines liability.

Contractor Provisions

Many state payroll tax laws extend to payments for services performed under contractor arrangements, particularly where there is a significant degree of control or integration.

Grouping Provisions

Related entities may be grouped for payroll tax purposes, potentially affecting threshold calculations and liability.
