An owner-operator is two things at once: the driver, who earns a living, and the owner, who runs a business that has its own income, costs and taxes. Most accounting problems for owner-operators come from treating those as one.
Structure
Many owner-operators start as sole proprietors, and a single-member LLC is taxed the same way by default. An LLC can protect personal assets in some situations, and at higher profits an S corporation election may reduce self-employment tax, but it also adds payroll and filing requirements. It is a decision to make with a preparer once you know what the business earns.
A separate account, from day one
Deposits go into the business account, truck costs come out of it, and you pay yourself with a transfer, called an owner draw. That single habit produces books that can be reconciled and a tax return that can be supported.
Settlement statements and carrier deductions
If you lease onto a carrier, your pay usually arrives as a settlement statement with deductions taken out for things like fuel advances, insurance or equipment. Record the gross amount as income and each deduction as its own expense. Reserve or escrow funds the carrier holds may be an amount owed back to you, not an expense, so check how they are described.
Taxes an owner-operator pays
- Income tax on the net profit of the business.
- Self-employment tax of 15.3% on net earnings: 12.4% for Social Security, up to an annual wage limit, and 2.9% for Medicare.
- Quarterly estimated payments, because no one withholds tax from your settlements.
At year end
A carrier that paid you as a contractor should send a Form 1099-NEC. Match it to your books: if the totals disagree, find out why before you file, not after a notice arrives.
