S-Corp Accountable Plan: How to Reimburse Personal Expenses Tax-Free
S-Corp shareholder-employees cannot deduct unreimbursed employee business expenses on their personal return (the TCJA/OBBBA permanently suspended the Schedule A deduction for unreimbursed employee expenses). However, the S-Corp can reimburse the shareholder-employee for business expenses through an accountable plan, and the reimbursement is tax-free to the employee and deductible by the S-Corp. This is one of the most overlooked S-Corp benefits.
An accountable plan under IRC 62(c) and Reg. 1.62-2 must meet three requirements: (1) The expense must have a business connection (the expense would be deductible if paid directly by the employer). (2) The employee must substantiate the expense (receipts, mileage logs, documentation) within a reasonable period (typically 60 days). (3) The employee must return any excess reimbursement within a reasonable period (typically 120 days). Expenses commonly reimbursed through an S-Corp accountable plan: home office expenses (the business-use percentage of rent, utilities, insurance, repairs), vehicle expenses (standard mileage rate or actual expenses), cell phone (business-use percentage), internet (business-use percentage), professional development, and business travel. The reimbursement is NOT included on the employee’s W-2 and is NOT subject to income tax or FICA. The S-Corp deducts the reimbursement as a business expense. The net effect: the expense reduces the S-Corp’s taxable income (and therefore QBI) while the employee receives the reimbursement tax-free.
How does the home office reimbursement work?
What other expenses can be reimbursed?
Vehicle: The S-Corp reimburses the owner at the standard mileage rate ($0.70/mile) for business miles driven in the owner’s personal vehicle. A 10,000-mile year generates a $7,000 tax-free reimbursement.
Cell phone: The S-Corp reimburses the business-use percentage of the owner’s personal cell phone plan. If the phone is 70% business use and the plan costs $100/month, the reimbursement is $840/year.
Internet: Same concept. If the home internet is 50% business use and costs $80/month, the reimbursement is $480/year.
Professional development: Courses, certifications, conferences, and books related to the business.
What are the requirements for the plan?
The accountable plan must be a written document adopted by the S-Corp (a board resolution or standalone policy). The document should specify: the types of expenses covered, the substantiation requirements (receipts within 60 days), the return-of-excess requirement (120 days), and the reimbursement process (expense report submitted to the corporation).
The plan does not need to be filed with the IRS. It must be maintained in the corporate records and followed consistently. If the plan’s requirements are not followed (no substantiation, no return of excess), the reimbursements become taxable compensation to the employee (reported on the W-2) and subject to FICA.
