Third Party Sick Pay

Third-party sick pay refers to sick pay benefits paid to an employee by an entity other than the employer—most commonly an insurance carrier under a short-term disability policy—when the employee is unable to work due to illness or injury. It differs from employer-paid sick pay in several important ways. When the employer pays sick pay directly, it is clearly treated as regular wages subject to standard payroll tax withholding. Third-party sick pay introduces additional complexity because the tax treatment depends on who paid the insurance premiums: if the employer paid the premiums, the third-party sick pay benefits are fully taxable to the employee; if the employee paid the premiums with after-tax dollars, the benefits are generally not taxable; and if premiums were split, a proportional analysis applies. The third party (insurer) typically assumes responsibility for withholding and remitting employment taxes on the benefits it pays, but specific reporting obligations depend on whether the insurer is designated as an employer's agent. Accurate classification is essential for proper W-2 reporting and payroll compliance. Aurora Training Advantage's Third Party Sick Pay webinar guides accounting and payroll professionals through these distinctions.

Third-party sick pay has specific W-2 reporting requirements that vary depending on the arrangement between the employer and the insurer. When the third party (insurer) is acting as the employer's agent and withholds and remits Social Security and Medicare taxes, the employer must include the sick pay in Box 1, Box 3, and Box 5 of the employee's W-2, and report the associated tax withholding in Boxes 4 and 6. If the insurer is not acting as agent, the insurer itself must issue a separate W-2 to the employee. In either case, Box 13 must be checked to indicate third-party sick pay is included, which triggers specific treatment on the employee's tax return. Taxable sick pay must also be included in state wage boxes where applicable. Reconciling third-party sick pay statements from insurers with payroll records is a common source of W-2 errors—particularly around timing differences between when benefits are paid and when the employer receives notification. Aurora Training Advantage's Third Party Sick Pay webinar provides accounting and payroll teams with step-by-step guidance on accurate W-2 reporting.

FICA tax obligations for third-party sick pay are governed by a set of rules that depend on the nature of the arrangement and the timing of payments. Generally, third-party sick pay that is taxable (because the employer paid the premiums) is subject to Social Security and Medicare taxes (FICA) for the first six months after the employee last worked. Sick pay paid more than six months after the employee's last day of active work is exempt from FICA, though it remains subject to income tax withholding if taxable. When the insurer acts as the employer's agent, it typically handles the employee portion of FICA withholding, while the employer is responsible for its own matching employer FICA contribution. The employer must then reconcile these amounts when preparing payroll tax returns (Form 941). Employers receive periodic statements from the insurer detailing third-party sick pay amounts paid, which must be accurately incorporated into payroll records to ensure FICA calculations are correct. Aurora Training Advantage's Third Party Sick Pay webinar walks payroll professionals through the FICA rules and reconciliation processes step by step.

Reconciling third-party sick pay with payroll records is one of the most error-prone aspects of year-end payroll processing, and a systematic approach is essential to produce accurate W-2s and payroll tax returns. The process begins with collecting the third-party sick pay statement from the insurer, which details amounts paid to each employee and the taxes already withheld and remitted by the insurer. These amounts must then be incorporated into the employer's payroll system to ensure they are reflected in each employee's year-to-date wage totals. Common reconciliation challenges include timing differences—sick pay paid in December may be reported by the insurer in January—and discrepancies between insurer records and employer records arising from mid-year changes in coverage or premium arrangements. The reconciled amounts feed directly into Form 941 quarterly returns and W-2 preparation. Employers should establish a clear process for requesting, receiving, and processing third-party sick pay statements on a regular cadence rather than scrambling at year-end. Aurora Training Advantage's Third Party Sick Pay webinar provides practical reconciliation frameworks for payroll and accounting teams.

Third-party sick pay is a frequent source of payroll compliance errors, many of which surface at year-end when W-2s are being prepared. The most common mistakes include: failing to include taxable third-party sick pay in the employee's W-2 wages because the employer was unaware of or late-received the insurer's statement; incorrectly treating non-taxable sick pay (employee-paid premiums) as taxable; miscalculating the FICA exemption for sick pay paid more than six months after the employee's last day of active work; omitting the Box 13 indicator on W-2s, which can cause issues on the employee's tax return; and failing to reconcile insurer statements with payroll records on Form 941. Preventing these errors requires establishing a clear internal process: designating a payroll owner for third-party sick pay administration, building a calendar for requesting and reconciling insurer statements, and auditing W-2s for proper third-party sick pay treatment before filing. Aurora Training Advantage's Third Party Sick Pay webinar equips payroll professionals with the knowledge and checklists to identify and prevent these common compliance pitfalls.
