Multi-State Tax for Trucking Companies: Nexus, Apportionment, and PL 86-272 Protection

A long-haul trucker might cross six or seven state lines in a single day. Each of those states has its own tax code, its own filing thresholds, and its own ideas about how much of your income belongs to them. Multi-state tax compliance is one of the most expensive headaches in trucking, not because any single state’s bill is enormous, but because the sheer number of filings, registrations, and estimated payments adds up fast. Miss a filing obligation and the penalties pile on. Misunderstand which states can actually tax you and you’ll either overpay (filing where you don’t have to) or underpay (ignoring a state that has jurisdiction over your income). Neither outcome is good.

What creates nexus for a trucking company?

Nexus is the legal connection between your business and a state that gives that state the constitutional authority to tax you. For current guidance, see Streamlined Sales Tax Project. For trucking, nexus almost always comes from physical presence. If you have a terminal, a warehouse, a maintenance facility, or any real property in a state, you have nexus there. If you have employees working in a state (drivers who are residents, mechanics at a shop, dispatchers in an office), you have nexus. If you lease or own equipment that’s permanently stationed in a state, you have nexus.

Driving through a state is where it gets more nuanced. Under the Commerce Clause and established case law, merely transporting goods through a state (picking up a load in State A and delivering it in State B, passing through State C along the way) doesn’t automatically create nexus for income tax purposes. But the threshold isn’t bright-line. If your trucks regularly make pickups and deliveries within a state, if you have drivers who overnight there regularly, or if you maintain fuel accounts or have other ongoing commercial activity, states will argue that you’ve crossed from transient presence into taxable nexus.

Some states have adopted economic nexus standards for income tax (not just sales tax), meaning they’ll assert jurisdiction if your revenue from sources within the state exceeds a dollar threshold, even without physical presence. This is still evolving and not universal for corporate income tax, but it’s a trend to watch. For most owner-operators and small fleets, physical presence remains the primary trigger.

The practical effect: an owner-operator based in one state who runs routes through multiple states every week needs to evaluate nexus in each state they touch. A fleet owner with a terminal in one state and drivers dispatched into six others has nexus in at least two or three of those states (and possibly all of them, depending on the nature of the activity).

Does PL 86-272 protect trucking from state income tax?

This is one of the most common misconceptions in trucking tax. Public Law 86-272, enacted in 1959, prohibits states from imposing a net income tax on a business whose only in-state activity is the solicitation of orders for sales of tangible personal property, provided those orders are sent outside the state for approval and the goods are shipped from outside the state. It was designed to protect traveling salespeople and their employers from filing income tax returns in every state they visited.

Here’s the problem for trucking companies: PL 86-272 applies to the solicitation of orders for tangible personal property. Trucking is a service. You’re transporting goods, not selling them. The freight itself belongs to the shipper or receiver, not the carrier. Because the trucking company is providing a service (transportation), PL 86-272’s protection simply doesn’t apply. The statute was never intended to cover service businesses, and courts have consistently held that it doesn’t.

This matters because trucking companies sometimes assume they’re protected when they’re not. If you have nexus in a state through physical presence (a terminal, regular pickups and deliveries, employees), that state can impose its income tax on you, and PL 86-272 won’t stop it. The protection that PL 86-272 provides to manufacturers who send salespeople into a state to solicit orders for goods does not extend to the trucking company that actually delivers those goods.

States have also been narrowing their interpretation of PL 86-272 in recent years. New York adopted regulations in December 2023 (upheld in April 2025 in the American Catalog Mailers Association case) that interpret the statute more restrictively, particularly around digital activities. H.R. 427 (the Interstate Commerce Simplification Act of 2025) proposed expanding PL 86-272 to cover digital solicitation activities, but that provision was not included in the final One Big Beautiful Bill Act. For trucking companies, these developments are mostly academic because the statute doesn’t protect them in the first place, but they illustrate the direction states are moving: toward more taxation, not less.

How do states apportion a trucking company’s income?

Once a state has nexus over your business, it doesn’t tax all of your income. It taxes the portion of your income attributable to activity within that state. The method for splitting your income among states is called apportionment.

For most businesses, states use a formula based on three factors: sales, payroll, and property (each measured as the state’s share of the total). Many states have moved to a single sales factor, weighting only revenue sourced to the state. But for motor carriers, a large number of states use a specialized mileage-based apportionment formula. The concept is straightforward: the percentage of your total miles driven in a particular state equals the percentage of your income that state can tax.

If your trucks drove 500,000 total miles during the year and 50,000 of those miles were in Illinois, then 10% of your apportionable income is taxable by Illinois. That’s the basic formula. Some states modify it (weighting the mileage factor differently, or blending it with revenue or payroll factors), but the core concept of miles-in-state divided by total-miles is the standard approach for motor carriers.

This creates a significant record-keeping obligation. You need to track miles driven in every state, every quarter, for every truck in your fleet. IFTA (International Fuel Tax Agreement) reporting already requires you to track fuel purchases and miles by jurisdiction, so the data infrastructure overlaps. But the income tax apportionment calculation is separate from IFTA, and the two don’t always use the same jurisdictional boundaries (IFTA covers the lower 48 states and Canadian provinces; state income tax is state-by-state within the US only).

For detailed IFTA compliance and fuel tax reporting, see the fuel tax and IFTA compliance guide.

What about states with no income tax?

Nine states impose no traditional individual or corporate income tax: Texas, Wyoming, South Dakota, Nevada, Florida, Tennessee, Washington, New Hampshire, and Alaska. For a trucking company based in one of these states, the home-state tax burden is zero (or close to it) on the income tax side. That’s a genuine advantage, and it’s one reason trucking companies cluster in Texas and Florida.

But “no income tax” doesn’t mean “no business tax.” Several of these states impose other taxes that hit trucking companies:

• Texas levies a franchise tax (often called the “margin tax”) on businesses with revenue exceeding $2.47 million (2026 threshold). It’s a gross receipts tax with limited deductions, not a net income tax, so PL 86-272 doesn’t block it. The rate is 0.375% for wholesalers and retailers, 0.75% for other businesses. Trucking companies generally pay 0.75% on their Texas-apportioned margin.
• Washington imposes the Business & Occupation (B&O) tax, a gross receipts tax with no deduction for cost of goods sold or business expenses. The rate for most services is 1.5%. If your trucking company has nexus in Washington, B&O tax applies.
• Ohio levies the Commercial Activity Tax (CAT) on gross receipts exceeding $150,000. The rate is 0.26% of taxable gross receipts over $1 million. Like the Texas margin tax and Washington B&O, it’s a gross receipts tax that PL 86-272 doesn’t cover.
• Tennessee repealed its Hall Income Tax (which applied to interest and dividends) effective 2021 and has no general individual income tax, but it does impose a franchise and excise tax on businesses.
• New Hampshire imposes a Business Profits Tax (8.5% on net income) and a Business Enterprise Tax (0.55% on the enterprise value tax base). Despite having no general individual income tax, New Hampshire taxes business income.

The takeaway: basing your operation in a no-income-tax state reduces your home-state burden, but it doesn’t eliminate your obligations in the states where you actually operate. And gross receipts taxes in states like Texas, Ohio, and Washington apply on top of whatever income tax other states impose on your apportioned income.

How does route planning affect state tax exposure?

Route planning is fundamentally a revenue and cost decision, but tax is part of the cost side. The more miles you drive in high-tax states, the larger the share of your income those states can claim. This doesn’t mean you should drive 200 extra miles to avoid crossing into California, because the fuel cost of the detour would exceed the tax savings. But when you’re choosing between roughly equivalent routes or deciding where to base operations, the state tax map matters.

States with high income tax rates and aggressive enforcement (California, New York, New Jersey, Minnesota, Oregon) will take a bigger bite of your apportioned income than low-tax or no-tax states. If you’re a fleet owner choosing where to locate a terminal, the income tax environment is a legitimate factor alongside real estate costs, labor availability, and proximity to freight lanes.

For owner-operators, the calculus is simpler: you go where the freight pays. But understanding which states are taxing you (and how much) helps you price loads accurately. A load that pays $3.50 per mile through low-tax states produces more after-tax profit than the same rate through high-tax states, all else equal.

What does multi-state compliance actually require?

The compliance burden is real and it’s ongoing. For each state where you have nexus, you’ll generally need to:

• Register as a foreign entity. Most states require out-of-state businesses to register with the Secretary of State before doing business in the state. There’s a registration fee and an annual report requirement.
• File a state income tax return. This is usually an annual return, due on the same schedule as the federal return (or shortly after). States that impose income tax on trucking companies require a return showing the apportioned income, the tax rate, and the tax due.
• Make estimated tax payments. States that impose income tax generally require quarterly estimated payments if the annual tax exceeds a threshold (often $500 or $1,000). Missing estimated payments triggers underpayment penalties and interest.
• Maintain apportionment records. Miles by state, revenue by state (if the state uses a revenue-based factor), and payroll by state (if the state uses a payroll factor). Your IFTA records cover miles, but you’ll need to maintain separate records for the income tax apportionment calculation.

For a small fleet running through eight or ten states, that can mean eight or ten state income tax returns, eight or ten sets of estimated payments, and eight or ten state registrations to maintain. Each return requires the apportionment calculation, and each state has its own form, its own rules, and its own due dates. The professional fees add up, but the cost of non-compliance (penalties, interest, and the risk of a state audit) is worse.

Multi-state compliance also intersects with other trucking tax obligations. IFTA covers fuel tax across jurisdictions. Form 2290 covers the federal heavy vehicle use tax. State-level vehicle registrations, base plates, and the International Registration Plan (IRP) are separate from income tax but part of the same compliance ecosystem. Keeping all of these current requires a system, not just a tax preparer who shows up once a year.

What should I do next?

If you’re running trucks through multiple states, start by mapping your nexus footprint. Where do you have physical presence? Where are your drivers based? Where do you make regular pickups and deliveries? That map tells you which states can tax your income. Then verify that you’re filing in every state where you have an obligation, and that your apportionment calculations are based on actual mileage data, not estimates.

If you’re choosing where to base a new operation or deciding whether to open a terminal in a particular state, factor the state tax cost into the decision. The difference between a no-tax state and a high-tax state compounds over years of operation.
