Why this matters for owner-operators and fleets

The National Taxpayer Advocate is warning that identity checks will continue to slow some refunds this filing season. In guidance published March 9, 2026, the Taxpayer Advocate Service (TAS) noted that during the 2024 filing season the IRS suspended processing of over 1.9 million returns pending identity verification—meaning millions of taxpayers had to take extra steps before a refund could be issued. For truckers who rely on timely refunds to cover fuel, maintenance, and insurance, understanding how to clear these checks quickly is critical.

How the IRS asks you to verify identity

If the IRS flags your individual return, you’ll receive a letter with instructions. The most common are: Letter 5071C (online or phone option), Letter 4883C (phone only), Letter 5747C (in-person appointment), and Letter 5447C (for foreign addresses, phone/mail options). Keep the letter—its number determines how you verify.

Only certain notices can be resolved online. The IRS’s Return Verification Service specifically supports the CP5071 series and Letter 5447C. If you got Letter 4883C, you must call; online verification won’t work for that notice. The IRS advises allowing two to three weeks for “Where’s My Refund?” to update after you verify, and up to nine weeks for full processing.

Steps truckers can take now

Get an Identity Protection PIN (IP PIN). Any taxpayer—including sole proprietors filing Schedule C—can opt in. An IP PIN is a unique six-digit number the IRS uses to confirm it’s really you; a new one is issued each year. If you enroll online, you’ll retrieve your PIN annually in your IRS account.
Set up your IRS online account before you need it. New users verify through ID.me, either via a self-service path (government ID plus selfie) or a live video chat that doesn’t require biometric data. TAS says selfies, video, and/or biometric data are automatically deleted except in suspected fraud cases.
Watch for IRS letters even when you’re over the road. If you misplace a notice, check your IRS online account for verification prompts; you can also call the Taxpayer Protection Program at 800-830-5084 (or 267-941-1000 from outside the U.S.).
Know your transcript codes. Code 570 usually signals a processing hold; code 971 often means the IRS issued a notice and is waiting on your response. Check transcripts in your online account to monitor movement.
Plan cash flow with realistic timelines. After you verify, give the IRS up to nine weeks to complete processing—build that into Q1 fuel, payroll, or repair budgets so a delayed refund doesn’t sideline a truck.

Owner-operator and fleet checklist for faster verification

Keep a copy of the exact return you filed (or have your preparer on standby). You’ll be asked to confirm line items from that return during verification.
Match addresses. If you’ve moved since last season—or operate from multiple terminals—update the IRS so notices reach you promptly.
If you receive Letter 4883C, call—don’t attempt the online tool. Have your letter, prior-year return, and current-year return available when you call.
Authorize your tax pro if needed. If you want a representative to speak with the IRS, ensure Form 2848 (Power of Attorney) is on file before you call so they can assist in real time.
Consider IP PINs for the household. If your spouse or dependents are listed on your return, enrolling them can reduce false flags tied to dependent information.

What about business identity theft?

Most identity verification letters relate to individual 1040 returns—even when you’re a sole proprietor running a truck with a DBA. If you operate an S corp or LLC with an EIN, monitor your IRS notices and account activity just as closely; the IRS also offers identity theft resources tailored to businesses and the self‑employed.

Bottom line

Identity verification is now a routine part of tax administration, not a personal red flag. For trucking businesses, the fastest path to a refund is straightforward: enroll in the IP PIN program, set up and maintain your IRS online account, respond immediately to any IRS notice using the method specified, and budget for the realistic processing window after verification. These steps won’t just protect your identity—they can keep cash flowing so your trucks keep rolling.
