Form 941 Implications

Taxable Fringe Benefits on Form 941 +
  • Line 2 (Wages): Include all taxable fringe benefits in total wages paid
  • Line 5a (Taxable SS Wages): Include FICA-taxable fringe benefits (including 401(k) deferrals, GTL >$50K imputed income)
  • Line 5c (Taxable Medicare Wages): Same as 5a; no wage cap for Medicare
  • Line 5d (Additional Medicare Tax): Applies to wages over $200,000 in a calendar year

Timing: Fringe benefits can be treated as paid on any date in the same calendar year, or by January 31 of the following year (special accounting rule). Many employers elect to value and include fringe benefits in the last payroll of the year or as a separate non-cash entry.

Imputed Income & Valuation Methods

When to Use Imputed Income +

Imputed income is the value of a non-cash benefit that must be added to an employee's gross income for tax purposes. Common scenarios:

  • Group term life >$50K: Use IRS Table I (Publication 15-B) to calculate monthly cost based on age brackets
  • Personal use of company vehicle: Use one of three IRS-approved methods
  • Domestic partner benefits: FMV of coverage for non-tax-dependent domestic partners
  • Below-market loans: Impute interest at the applicable federal rate (AFR)
Vehicle Valuation Methods +
MethodHow It WorksBest For
Annual Lease Value (ALV)Use IRS annual lease value table based on FMV of the vehicle. Multiply by personal use percentage.Vehicles available for both business and personal use year-round
Cents-per-MileMultiply personal miles by the standard mileage rate (67 cents/mile for 2024; check 2026 rate). Vehicle FMV must not exceed $62,000 (2024; check 2026 threshold).Low-value vehicles or infrequent personal use
Commuting Rule$1.50 per one-way commute ($3.00 round trip). Requires written policy and specific conditions.Vehicles provided for commuting only, with strict personal use controls

Third-Party Sick Pay Reporting

Form 8922 & Third-Party Sick Pay Rules +

Form 8922 (Third-Party Sick Pay Recap) reconciles sick pay reported on Forms W-2 and 941 between the employer and the third-party payer (insurance company).

  • Third-party sick pay is taxable to the employee
  • If the employer bears the insurance cost, the payments are subject to FICA and FUTA
  • If the employee bears the cost, payments are subject to FICA only for the first 6 months after the last month worked
  • The third-party payer and employer must agree (typically via Form 8922) on which entity reports the wages and withholding on Form W-2
  • The employer is always liable for the employer share of FICA taxes

W-2 Reporting: Sick pay may be shown on a separate W-2 issued by the third-party payer, or combined on the employer's W-2. Check Box 13 "Third-party sick pay" if applicable.
