IRS Rules for Vehicle Allowances: FAVR, 463, and Non-Taxable Plans

Written by mBurse Team Member   |   Oct 11, 2024 7:00:00 AM

When it comes to understanding vehicle allowances, navigating the intricacies of tax regulations can be daunting. The Internal Revenue Service Publication 463 provides guidance, but it is 60 pages long. Here is our shorter guide to the tax implications of different vehicle allowance programs.

What is IRS Publication 463?

Publication 463 is an IRS document that provides detailed information on travel, gift, and car expenses. It is a valuable resource for anyone who needs to report these expenses on their tax returns. The publication can also help businesses determine which payments to employees are taxable and which ones are non-taxable.

Key Points from Publication 463 (for Vehicle Allowances)

  • Accountable Plans: Payments made under accountable plans are tax-free. Payments cannot exceed the equivalent of the standard federal rate and require timely records. Any payments above the federal rate must be returned or become taxable.

  • Recordkeeping Requirements: All tax-free payments require records to prove business use of the vehicle. Records must include the amount of the expense, the date, and the destination of each trip. The amount is determined by the mileage accrued.

  • Nonaccountable Plans: Plans that do not meet the criteria of an accountable plan are taxable. These plans do not require recordkeeping. Payments are included in the employee's wages or salary.

Understanding Vehicle Allowances

Vehicle allowances are payments made to employees for the business use of their personal vehicle. These allowances can be structured in different ways, and understanding these structures is crucial for both tax compliance and financial planning.

Types of Vehicle Allowances

  1. Fixed and Variable Rate (FAVR): This method reimburses employees based on a combination of a fixed monthly amount and a variable mileage rate. The fixed amount covers costs like insurance, while the cents-per-mile rate covers fuel and maintenance.

  2. Cents-Per-Mile Rate: This is a straightforward method where employees are reimbursed a set amount per mile driven for business purposes. The IRS sets a standard mileage rate annually, which serves as a guide for this reimbursement.

  3. Flat Allowance: Employees receive a set amount regardless of the miles driven. This type of allowance can be taxable if it doesn't meet IRS guidelines for an accountable plan. However, if the employee properly records mileage and returns any amount over the equivalent of the mileage x the federal rate, then the remainder may be tax-free.

Are Vehicle Allowances Taxable?

Whether a vehicle allowance is taxable depends on how it is structured and documented. The IRS has specific guidelines that determine the taxability of these allowances.

Non-Taxable Vehicle Allowance

To be considered non-taxable, a vehicle allowance must meet the criteria established by publication 463:

  • Accountable Plan: The employee must substantiate the business use of their vehicle and return any excess reimbursements to the employer. The excess is determined either by multiplying mileage by the federal rate or by calculating actual expenses. The federal rate can either be a fixed and variable rate (FAVR) or the standard mileage rate.

  • Documentation: Employees must provide adequate documentation, such as mileage logs, to support the business use of their vehicle. Many businesses now use mileage tracking apps to streamline recordkeeping.

Taxable Vehicle Allowance

If an allowance does not meet the IRS requirements for a non-taxable vehicle allowance, it is considered taxable income. This means:

  • The allowance will be included in the employee’s gross income.
  • Taxes will be withheld from the allowance amount.

Federal Reimbursement Rates from 463

Each year the IRS establishes a maximum federal rate for reimbursing vehicle costs tax-free. This rate is designed to cover the cost of operating a vehicle for business purposes, including fuel, maintenance, and insurance. The federal rate can be calculated two different ways.

Standard Mileage Rate

The IRS publishes three standard mileage rates each year: for business, charitable, and medical purposes (as well as moving purposes for military). The standard business rate is the one that individuals and businesses can use to determine tax liability. For 2024, that rate is 67 cents per mile.

Fixed and Variable Rate

A fixed and variable rate (FAVR) program also derives from federal guidelines. The employer sets rates using a standard vehicle and then individualizes rates based on each employee's garage zip code. The standard vehicle's value cannot exceed a set limit. For 2024, that limit is $62,000.

Recordkeeping and Documentation

Proper recordkeeping is essential for both employers and employees to ensure compliance with IRS regulations regarding vehicle allowances.

Importance of Accurate Recordkeeping

  • Substantiation: demonstrate business use of a vehicle.
  • Tax Compliance: determine whether taxable vs. non-taxable.
  • Audit Protection: provide documentation in case of an IRS audit.

Recommended Documentation

  • Mileage Logs: Detailed logs that record the date, purpose, and miles driven for each business trip. This is necessary for FAVR plans, cents-per-mile plans, and 463 accountable allowances.
  • Receipts: Keep receipts for any expenses related to the business use of the vehicle. These receipts are necessary when using the actual expense method instead of the federal rate.

IRS Publication 463 and Your Business

Publication 463 is a comprehensive guide that provides valuable insights into the tax implications of vehicle allowances. With knowledge of the rules in 463, employers and employees can make informed decisions and ensure compliance with IRS regulations.
