The Taxpayer Times

What Truckers Can Actually Deduct (And What Gets Them in Trouble)

Where the Confusion Begins

After the business is set up, the next question usually comes quickly:

” What can I deduct?”

In the trucking industry, this question is often shaped by informal conversations – other drivers, dispatchers, or online discussions.

Some of that information is helpful. Much of it is based on individual experiences.

What works in one situation does not always apply in another – especially when it comes to taxes.

The result is not usually intentional misreporting. It is a mix of assumptions, partial information, and inconsistent records.

What a Deduction Actually Means

A business deduction is not simply anything related to the truck or the work.

In general terms, a deductible expense must be:

• ordinary (common in the industry)
• necessary (appropriate for the business)

That sounds simple, but in practice, the difficulty is not understanding the rule – it is applying it consistently.

Common Deductible Expenses (In Practice)

For most small trucking businesses, the core expenses are straightforward:

• fuel
• repairs and maintenance
• insurance
• tolls and parking
• licenses and permits

These are typically not where problems begin.

The issues usually arise in areas where:

• personal and business use overlap
• timing matters
• or the treatment is not intuitive

Truck Payments vs. Depreciation

One of the most common misunderstandings is how truck costs are deducted.

Many owner-operators assume:

“If I’m making a truck payment, I can deduct the full amount.”

That is not how it works.

The cost of the truck is generally recovered through:

• depreciation (over time or through accelerated methods)
• interest expense (the financing portion of the payment)

The principal portion of a loan payment is not a deductible expense.

This is a common area where expectations and actual tax results do not align.

Per Diem – Often Misunderstood

Per diem is widely discussed in the trucking industry and often misunderstood.

At a high level, it is intended to account for:

• meals and incidental expenses while traveling away from home

However:

• not every driver qualifies
• the calculation must follow specific rules
• the treatment can differ depending on the business structure

This is an area where informal advice frequently leads to incorrect assumptions.

We will look at this in detail in a separate part of this series.

Mixed Personal and Business Expenses

Some expenses do not fall neatly into “business” or “personal.”

Examples include:

• cell phones
• internet
• vehicles used for both personal and business purposes

In these cases:

• only the business portion is deductible

Without clear records, it becomes difficult to support how that percentage was determined.

Recordkeeping – Where Problems Actually Begin

Most deduction issues are not about the rule itself.

They begin with recordkeeping.

In many small trucking businesses:

• receipts are incomplete
• mileage is not consistently tracked
• expenses are reconstructed at year-end

When records are not maintained throughout the year:

• deductions become estimates
• consistency breaks down
• the tax return no longer reflects actual activity

This is where small issues begin to compound.

When “Common Practice” Becomes a Problem

In the trucking industry, it is not unusual to hear:

“Everyone does it this way.”

However, common practice is not the same as correct treatment.

Tax reporting is based on:

• documented activity
• consistent application of rules
• supportable records

When those are missing, the position taken on a return becomes difficult to defend.

How This Connects to Larger Issues

Incorrect or unsupported deductions can lead to:

• understated income
• unexpected tax balances
• notices or examinations

In many cases, the issue is not a single large mistake.

It is a series of small decisions made over time:

• relying on informal guidance
• inconsistent tracking
• assumptions about what is deductible

Looking Ahead

Understanding deductions is not just about identifying expenses.

It is about:

• how those expenses are tracked
• how they are calculated
• and how they are reported over time

One of the most frequently discussed – and misunderstood – areas in trucking is per diem.
