Your role in tax prep

If you want to avoid the most common mistakes I see with owner-operator tax returns, you need to get involved in checking the major numbers your tax preparer is using. Doing this can save thousands of dollars in taxes. Or it could save you from thousands of dollars in penalties and interest if your preparer makes a stupid mistake in your favor.

Here’s the worst mistake I uncovered in a tax review this year. Though the return had been prepared by a trucking specialist, the husband-wife team had a feeling something wasn’t right and questioned the preparer about it repeatedly.

The couple had shown a net operating loss on their Schedule C for seven years. The only reason I’ve ever seen for a net operating loss is high depreciation. The problem with their most recent tax return was that there was less than $1,500 in depreciation.

The preparer, following settlement sheets that separated mileage pay from fuel surcharge pay, was including only mileage revenues in the gross numbers. Fuel surcharge payments were listed under “reimbursements,” which is not standard accounting practice.

So gross revenue was less than $100,000 each year, even though the per diem showed more than 250 days on the road each year. This is an absolute giveaway that the gross revenue is incorrect.

This mistake resulted in under-reporting income by $20,000 to $40,000 per year for seven years. Tax was underpaid by $3,500 to $7,000 per year. With interest and penalties, the liability could be as high as $75,000.

Here’s what you can do to avoid such situations:

SPOT CHECK YOUR 1099 TOTAL. Most leased owner-operators make around $1.20 per mile with the fuel surcharge included. The number of dollars on your 1099 should be significantly higher than the number of miles you ran during the year. If they’re similar, it’s close to $1 a mile, indicating missing surcharge revenue.

VERIFY THE ACCURACY OF THE 1099 AMOUNT. Having established that amount is reasonable, go further. A relatively small mistake – say, $5,000 – wouldn’t jump out, yet you would pay $1,000 in tax you didn’t owe. Verify the amount by adding each settlement to determine your 1099 revenue.


• Fuel. You know roughly what your weekly fuel spending is. Multiply that by 50 to get a year’s estimated total.

• Maintenance. See how your big expenses add up. If you know you had one $8,000 repair, for example, and total maintenance is just over $10,000, there’s probably a mistake.

Fuel, maintenance and per diem are three major cost categories for which you should do a rough estimate to double-check your accountant.

• Per diem. Look at your Schedule C for meals and entertainment. Take the total number of nights away from home and multiply it by $59. Then multiply that number by 0.8. That should be your total deductible per diem.

If you find mistakes or red flags on one of these categories, continue checking the entries, from largest dollar amount to smallest. If amounts in these three are correct, odds are the tax return has been prepared correctly. strives to maintain an open forum for reader opinions. Click here to read our comment policy.
