No employer is withholding tax for you anymore
Running your own authority means you're self-employed for tax purposes — which changes almost everything about how, and how often, you deal with the IRS.
Instead of a paycheck with tax already withheld, you report business income and expenses on Schedule C, pay self-employment tax on your net profit, and are generally expected to send the IRS quarterly estimated payments throughout the year rather than settling up once in April. On top of that, you're the one who has to substantiate meal costs while on the road, track what a truck purchase is really worth for depreciation, and know how long to actually keep the paperwork behind all of it.
This guide covers the recordkeeping side of that picture — not tax strategy or how to minimize what you owe, which is exactly the kind of decision worth a conversation with a qualified tax professional who knows your full situation.
The retention clock resets differently for almost every kind of record
Tax recordkeeping doesn't run on one timer. The general rule is 3 years from when you filed, but that stretches to 6 years if income was underreported by more than 25%, and indefinitely if a return was never filed at all. Records tied to a truck's depreciation need to be kept even longer — until the limitations period runs out for the year you eventually sell or dispose of it, which can be well past when you'd otherwise think to shred anything.
There's also a change worth knowing about directly: starting with money received in 2026, the threshold for a broker or shipper to send you a 1099-NEC rose from $600 to $2,000 a year under recent federal law. That doesn't reduce what you owe — you still have to report every dollar of income whether or not a 1099 shows up — but it does mean you may see fewer 1099s than in past years and need your own records to fill the gap.
What every owner-operator should understand about tax records

Quarterly estimated taxes are generally due April 15, June 15, and September 15, with a final payment due January 15 of the following year (for 2026: April 15, June 15, September 15, 2026, and January 15, 2027). Missing a quarter can trigger an underpayment penalty even if you're due a refund at filing time.

Self-employment tax is 15.3% of net earnings — 12.4% for Social Security and 2.9% for Medicare — calculated on Schedule SE and paid on top of regular income tax. For 2026, the Social Security portion applies only to the first $184,500 of net self-employment income; Medicare applies with no cap.

The transportation industry per diem rate for meals and incidental expenses is $80 per day (CONUS) as of the current rate period beginning October 1, 2025. Owner-operators deduct meal costs on Schedule C rather than receiving an employer per diem payment, and still need to document each day away from home to support it.

1099-NEC reporting thresholds changed starting with 2026 payments: the threshold rose from $600 to $2,000 per year under recent federal law. You're still required to report all income regardless of whether a 1099 arrives — don't rely on the form itself as your income record.

A truck is generally eligible for full first-year expensing under Section 179 and/or bonus depreciation, subject to 2026 limits and business-use requirements. That deduction depends on documentation — purchase invoice, placed-in-service date, and business-use percentage — that needs to be kept for the life of the asset, not just the year you bought it.

IRS record retention isn't one timer: generally 3 years from filing, but 6 years if income was underreported by more than 25%, and indefinitely if a return was never filed or was fraudulent. Records supporting a truck's depreciation basis need to be kept until the limitations period expires for the year you dispose of it.

Mileage records for taxes and for IFTA overlap, but they're not the same thing. IFTA tracks miles by jurisdiction for fuel tax purposes. Your tax records separately need to support business-use percentage and per diem days away from home, whichever deduction methods you actually use.
