Tax Advantages for Our Drivers

About Our Per Diem Plan

As of January 1, 2018, employee drivers are no longer allowed to claim unreimbursed employee business expenses, like meals per diem, as a tax deduction on their federal income tax return. Atlantic HR Solutions is introducing an accountable, company-paid per diem plan for fleet client’s in response to this tax law change.

Which drivers receive per diem?

  • Only drivers who travel away from home overnight where sleep or rest is required and participate in a company sponsored per diem program, like AHRS Mobile, can take advantage of the substantial tax benefits that come with per diem.
  •  A driver who starts and ends a trip at home on the same DOT HOS 14-hour clock cannot receive per diem.

What are the typical tax savings to a driver receiving per diem?

A driver will typically save up to $4,700 in taxes, which is equivalent to about 4 cents per mile.

What is per diem?

A per day travel expense allowance paid to an employee as an expense reimbursement under an accountable per diem plan.

Is company-paid per diem taxable to an employee driver?

No. It is considered a non-taxable reimbursement that is deducted from taxable wages.

  • Amounts paid under the per diem plan are tax free, not reportable as wages on Form W-2, and are not subject to income or employment taxes.
  • Be aware that the program reallocates your income; the non- taxable reimbursement is not in addition to your base wages.

How will per diem affect my Social Security?

The per diem pay plan will reduce social security benefits. However, you still come out ahead because you could save thousands in taxes each year under the per diem program and only lose out on $4 to $11 per month in social security benefits. Speak with a tax advisor for more information about your situation.

How do I track a truck driving trip?

  • The app will begin tracking your trip automatically when you exit the tax home halo defined by your company and record per diem daily
  • Per diem is posted the next afternoon, which includes 34-hour restarts and unforeseen delays
  • The app ends a trip automatically when you return home
  • View the "Starting a Trip" User Guide

How much per diem will I receive?

  • $69 / day for each FULL day you are away from home (Start your trip BEFORE noon or return home AFTER noon).
  • $51.75 / day for each PARTIAL day you are away from home (Start your trip AFTER noon or return home BEFORE noon).

Does a driver have to spend all the per diem?
