Reimbursement under an Accountable Plan for S Corporation - A Complete Guide by Z-Tax & Accounting

S Corporation owners and employees can benefit from accountable plans to reimburse business expenses tax-free while complying with IRS rules. Properly implementing an accountable plan allows S Corporations to deduct legitimate expenses and avoid unnecessary payroll taxes, making it a powerful tool for tax planning.

This guide covers what an accountable plan is, eligible reimbursements, documentation requirements, and key strategies for S Corporations.

What is an Accountable Plan?

An accountable plan is a reimbursement arrangement used by S Corporations to reimburse employees or shareholder-employees for business-related expenses without the reimbursement being counted as taxable income.

To qualify as an accountable plan, the arrangement must meet three IRS requirements:

1. Business Connection
   
   

   • The expense must have a legitimate business purpose.
     
     

2. Substantiation
   
   

   • The employee must document the expense with receipts, invoices, or other supporting records.
     
     

3. Return of Excess Reimbursements
   
   

   • Any excess reimbursement must be returned to the S Corporation within a reasonable period.
     
     

Eligible Expenses Under an Accountable Plan

S Corporations can reimburse a variety of business-related expenses, including:

• Travel expenses (airfare, hotels, meals while traveling)
  
  

• Vehicle expenses for business use
  
  

• Office supplies and equipment
  
  

• Professional licenses and dues
  
  

• Business meals (subject to 50% or 100% IRS rules)
  
  

• Continuing education or training related to the business
  
  

These reimbursements are tax-free to the employee and deductible by the S Corporation, reducing overall taxable income.

Documentation Requirements

Benefits of Using an Accountable Plan

1. Tax-Free Reimbursement
   
   

   • Employees and shareholder-employees do not report the reimbursement as income, avoiding payroll and income taxes.
     
     

2. Corporate Deduction
   
   

   • S Corporations can deduct reimbursements as ordinary business expenses on Form 1120S.
     
     

3. Simplified Record-Keeping
   
   

   • A well-documented accountable plan reduces the risk of IRS audits.
     
     

4. Flexibility for Shareholder-Employees
   
   

   • Owners who are employees of the S Corp can reimburse themselves for business expenses without increasing W-2 wages.
     
     

Best Practices for S Corporations

• Establish a Written Accountable Plan
  
  

  • Clearly outline the types of reimbursable expenses, documentation requirements, and submission timelines.
    
    

• Ensure Business Purpose
  
  

  • Only reimburse expenses that are ordinary and necessary for the S Corp’s operations.
    
    

• Maintain Proper Records
  
  

  • Keep receipts, invoices, and mileage logs organized for audit compliance.
    
    

• Return Excess Reimbursements Promptly
  
  

  • Any overpayment must be returned to the S Corporation to maintain tax-free treatment.
