What it means
The core idea is that getting yourself to your job is your own affair, not the employer's cost of doing business. Once you arrive at your regular workplace, travel from there to a client, a supplier or a second site becomes business travel and is generally deductible.
That line sounds simple but produces a lot of arguments in practice. A salesperson who drives from home directly to a customer, a contractor with several sites, and a hybrid worker who visits the office twice a week all sit near the boundary, and the answer often turns on whether the home counts as a principal place of business.
For a business, commuting expenses matter in two ways: as a cost you may choose to subsidise, and as a payroll and tax question. If you reimburse an employee's train season ticket or parking, that reimbursement is usually treated as taxable pay unless a specific commuter benefit rule allows otherwise, so the true cost to the company includes the payroll taxes on top.
Employees care about the number because it is a real reduction in take-home pay that never shows up on a payslip. A job paying $5,000 more but adding an hour and $4,000 a year of travel is not the raise it looks like, which is why relocation, hybrid working and office location decisions are as much financial as cultural.
The common variants are worth knowing. A temporary workplace, generally one you expect to attend for a limited period, is often treated as business travel rather than commuting, and travel between two workplaces on the same day is normally deductible even when the first leg was not.
In practice
Real-world examples.
Example
A regional accounting firm moves its office from a suburb to the city centre to attract graduates. Three senior staff calculate that parking and tolls will add roughly $3,000 each a year, and the firm agrees a $150 monthly travel allowance to keep them, treating it as taxable pay through payroll.
Example
A field engineer for a lift maintenance company starts each day driving from home to the depot to collect parts. That first leg is a commute, but every journey after it, from depot to customer and customer to customer, is business travel and goes on the mileage claim.
Example
A marketing consultant works from a home office four days a week and visits one long-term client the fifth. Because that client site has become a regular workplace over an 18 month engagement, her accountant treats the weekly trip as commuting rather than a deductible business journey.
Formula
Calculation
Annual commuting cost = round trip distance x commuting days per year x cost per mile.
Consider an employee who drives 30 miles round trip to the office, works in the office 230 days a year, and estimates the all-in running cost of the car at $0.70 per mile including fuel, servicing, tyres and depreciation.
Annual mileage = 30 miles x 230 days = 6,900 miles.
Annual commuting cost = 6,900 miles x $0.70 = $4,830.
If the employer pays a $200 monthly commuting allowance, that is $2,400 a year of extra taxable pay, so the employee still bears $2,430 of the cost before tax on the allowance is even considered.Case study
Seen in the real world.
Northvale Cartography is an illustrative, entirely fictional mapping business with 40 staff and an office on the edge of a mid-sized city. When the landlord ended free parking, staff faced about $180 a month each in city car parks, and two people resigned within a quarter citing the cost.
The finance director modelled a $150 monthly commuting stipend for all 40 staff, which came to $150 x 40 x 12 = $72,000 a year, plus payroll taxes because the stipend counted as pay. She compared that with the cost of a hybrid policy that cut required office days from five to three, which reduced each employee's commuting spend by roughly 40% at no direct cost to the company.
The company chose the hybrid policy and put $20,000 of the saved budget into a subsidised transit pass for the staff who could not work from home. The lesson in this fictional case was that commuting expenses are best managed by changing the journey rather than by paying for it.
Watch out
Common mistakes.
- Assuming that because a journey is made for work reasons it is automatically deductible. Travel from home to your regular workplace is a personal cost in most tax systems, however early the start or however far the distance.
- Reimbursing commuting costs through expenses rather than payroll. Unless a specific commuter benefit rule applies, that reimbursement is pay and attracts payroll taxes, and treating it as an expense can create a compliance problem at audit.
- Ignoring commuting cost when comparing job offers or office locations. A longer commute is an unpriced pay cut for staff and a hidden driver of turnover for the employer.
Questions
People also ask.
Does working from home make my trips to the office deductible?
Usually not by itself, because if the office remains a regular workplace the trip stays a commute, though the position can change where the home is genuinely the principal place of business.
Are parking fines and speeding tickets on a commute ever recoverable?
No, penalties are never deductible business costs and reimbursing them creates taxable pay for the employee.
What about travel to a site you will only attend for a few months?
Travel to a genuinely temporary workplace is often treated as business travel rather than commuting, but the rules set limits on duration and expectation, so the position should be confirmed before claiming.
