IRS Form 2290 Schedule 1 Instructions: How to Complete It

The IRS Form 2290 Schedule 1 instructions come down to one job: list every heavy vehicle you are reporting, by VIN and weight category, on the same return that pays your Heavy Highway Vehicle Use Tax. You enter your name, address, EIN and month of first use. You count your vehicles in Part I and list each VIN with a category letter in Part II. Then you file both copies with Form 2290 by the last day of the month after first use. The IRS stamps one copy and returns it, and that stamped Schedule 1 is your proof of payment.

The trouble is that the rules are spread across a long instruction booklet, and small slips cost real time. One wrong VIN character, a vehicle count that does not match the tax table, or the wrong month of first use can trigger a rejection, a late penalty, or a DMV that will not renew your tags. Most filers only read the instructions after something has already gone wrong.

This guide walks through the current revision, which covers July 1, 2026 through June 30, 2027, in seven steps, followed by a section on fixing mistakes. TruckTaxPro is an IRS-authorized e-file provider that works only on Form 2290, so the guidance is built around where filers get stuck. You will see the weight table, the due-date table, a worked example, and the exact rules for suspended and used vehicles.

What Schedule 1 is and what to gather first

Schedule 1 is the vehicle list that you attach to Form 2290. The IRS stamps it after processing, and the stamped copy is what your state DMV wants to see. Before you fill in a single box, confirm that your vehicle needs reporting and collect five pieces of information.

What Schedule 1 does

Form 2290 is the return that calculates your tax. Schedule 1 reports each vehicle by VIN and category, including vehicles on which you are suspending the tax. The IRS stamps the second copy and returns it to you, and you use that copy as proof of payment to register your vehicle in any state, unless the vehicle is specifically exempt.

Your return may be rejected if Schedule 1 is missing. Canadian and Mexican vehicles need it too: U.S. Customs and Border Protection requires proof of payment before such a vehicle enters the United States.

Use the revision that matches your period. The July 2026 revision of Form 2290 and Schedule 1 is for the period that began July 1, 2026. Do not use it for a period that began on or before June 30, 2026. Earlier revisions are listed on the IRS Form 2290 page.

Form 2290 is the tax return, and Schedule 1 is the proof that you paid.

Who has to file

You file when a highway motor vehicle with a taxable gross weight of 55,000 pounds or more is registered, or required to be registered, in your name at the time of its first use in the period. That covers trucks, truck tractors and buses. Vans, pickups and panel trucks usually fall under 55,000 pounds and are not taxed.

The filer can be an individual, LLC, corporation, partnership or nonprofit. If a vehicle is registered in two names, including a leased vehicle, the owner is liable. Government vehicles, the American National Red Cross, nonprofit volunteer fire and rescue units, and a few other users are exempt, so they do not report on Form 2290.

You must e-file any return that reports and pays tax on 25 or more vehicles. Suspended vehicles (category W) do not count toward that threshold.

What to have ready

Gather these before you start:

• Your EIN. You cannot use a Social Security number. Apply online at IRS.gov/EIN if you do not have one.
• The VIN of each vehicle. Take it from the registration, title or the truck itself, never from the trailer.
• The taxable gross weight of each vehicle, which Step 1 explains.
• The month each vehicle was first used on a public highway in this period.
• A payment method: direct debit with e-file, EFTPS, a card, or a check or money order.

Step 1. Work out taxable gross weight and category

Your taxable gross weight decides your category, A through V, and the category decides your tax. Get this wrong and both Form 2290 and Schedule 1 carry the wrong letter for that VIN.

How the IRS counts weight

For a truck or tractor, taxable gross weight is the sum of three things:

1. The actual unloaded weight of the vehicle, fully equipped for service.
2. The actual unloaded weight of any trailers or semitrailers customarily used with it.
3. The weight of the maximum load customarily carried on the vehicle and those trailers.

"Fully equipped for service" means the body, accessories, attached equipment and a full supply of fuel, oil and water. It does not include the driver. A trailer counts as customarily used if the vehicle is equipped to tow it. For a bus, the weight is the unloaded weight fully equipped for service plus 150 pounds for each seat provided for passengers and the driver.

State registration can raise your number

The weight you declared to a state can override your own math. If any state requires a declaration of a specific gross weight, your taxable gross weight must be no less than the highest weight declared in any state. For a tractor-trailer combination, use the highest combined weight declared.

If a state registers by weight category, your weight must fall in the highest category for which the vehicle is registered. If you register only in states that go by unloaded weight, use the three-part total above.

Ignore weights declared for special temporary travel permits, unless those permits cover more than 60 days, or more than 2 months if issued monthly, during a tax year.

Your taxable gross weight can never be lower than the highest weight you declared to any state.

Find your category and annual tax

The annual tax is $100 for 55,000 pounds plus $22 for each additional 1,000 pounds, capped at $550 for anything over 75,000 pounds. Logging vehicles pay 75% of those amounts. These are the figures for a vehicle first used in July 2026.

Write down the letter for each VIN now. You will need it twice: once in the tax computation on Form 2290 and once in Part II of Schedule 1.

Step 2. Enter the correct month of first use

The month of first use is the month you first drove the vehicle on a public highway during the tax period, written as year and month, such as 202607. It controls your due date and whether you pay the full annual tax or a partial-period amount. It must be the same on Form 2290 line 1 and at the top of Schedule 1.

Pick your code and deadline

"Use" means driving the vehicle on a public highway under its own power. Driving a new truck home from the dealer counts as first use. You must file by the last day of the month after the month of first use, whatever your state registration date is. If the date lands on a weekend or legal holiday, file by the next business day.

If you first use vehicles in more than one month, file a separate Form 2290 and Schedule 1 for each month. Trucks first used in July go on one return due August 31. Trucks first used in August go on another due September 30.

File by the last day of the month after first use, no matter when your registration renews.

Full year or partial period

A vehicle first used in July pays the full annual tax from the table in Step 1. A vehicle first used after July pays a partial-period tax based on the number of months left in the period, which ends June 30. The exact amounts are in Table I at the back of the IRS instructions, and Table II covers logging vehicles. Look the amount up instead of estimating it. A truck first used in November 2026, for example, is figured for November through June.

Used trucks bought from a private seller

Special rules apply when you buy a used truck from a private seller who has already paid the tax for the period. Suppose the sale happens on or after July 1, 2026 and before June 1, 2027, and your first use is in the month of sale. Your tax starts the month after the sale, and you enter that following month on line 1. Your due date does not change.

Here is the IRS example. Linda paid the full $550 on July 2, 2026 for an 80,000-pound truck. John bought it on September 9, 2026, and drove it home the next day. His tax runs October through June, which is 9 months out of 12.

John's return is still due by the end of October, which in 2026 means November 2 because October 31 falls on a Saturday. Before you rely on this rule, confirm that the seller paid, for example with a copy of the seller's stamped Schedule 1.

Step 3. Fill in the header and Part I

The top of Schedule 1 repeats your Form 2290 details, and Part I summarizes your vehicle counts. These boxes are quick to fill, and they are where mismatches with Form 2290 show up.

Copy the header exactly

Enter your name and address on Schedule 1 exactly as shown on Form 2290, and make sure the EIN matches page 1 of the return. Include a suite or room number. If the post office does not deliver to your street address, use your P.O. box number instead. For a Canadian or Mexican address, follow that country's practice for the postal code and do not abbreviate the country name.

Then enter the month of first use from Step 2 in the "Month of first use" box, in YYYYMM format. If you have moved, check the Address Change box on Form 2290.

Complete lines a, b and c

Part I is a three-line summary:

• Line a: the total number of vehicles reported on Schedule 1, taxable and suspended.
• Line b: the number of taxable vehicles on which the tax is suspended (category W).
• Line c: the number of taxable vehicles, which is line a minus line b.

Line c should equal the vehicle total in column (3) of the tax computation on Form 2290 page 2. If those two numbers differ, one of the forms is wrong. Fix it before you file.

Here is a worked example for one July filing that reports four vehicles:

For this return, line a is 4, line b is 1 and line c is 3. The total tax on Form 2290 is $550 + $364 + $166 = $1,080.

Line c on Schedule 1 must equal the taxable vehicle total on Form 2290 page 2.

Step 4. List every VIN and category in Part II

Part II is the core of the Schedule 1 instructions: one line per vehicle, each with a 17-character VIN and a category from A to V, or W for a suspended vehicle. A page holds 24 vehicles. If you owe tax on 25 or more vehicles, you must e-file anyway.

Enter VINs without errors

Take each VIN from the registration, the title or the vehicle itself, and be sure it belongs to the truck, not the trailer. A VIN has 17 characters made up of numbers and letters. Real VINs never use the letters I, O or Q, so if you see one, you have probably misread a 1 or a 0.

Read each VIN twice, then compare it with the registration. A single wrong character produces a Schedule 1 that does not match your DMV record, and the fix means another filing. When you file with TruckTaxPro, each VIN is checked against the 17-character standard as you type, and bulk add and CSV upload help with larger fleets.

Match each VIN to its category

Write the category letter from Step 1 next to each VIN. For the four-vehicle example, Part II would read like this, with your own VINs in place of the placeholders:

Do not put a vehicle on Schedule 1 unless it is reported on that return's Form 2290. Each vehicle appears on the Schedule 1 for its own month of first use.

Suspended vehicles and category W

You can suspend the tax on a vehicle you expect to use 5,000 miles or less on public highways during the period. For agricultural vehicles the limit is 7,500 miles. List the vehicle in Part II with category W, check the matching box on line 7 of Form 2290, and count it on line b of Part I. You still get a stamped Schedule 1 for it.

An agricultural vehicle is one used primarily for farming, meaning more than half its mileage, and registered as a farm vehicle for the entire period. Miles driven on the farm itself do not count toward the 7,500-mile limit, so keep accurate records.

The mileage limit applies to the vehicle across all owners during the period. If a suspended vehicle goes over the limit, the tax becomes due and you must file an amended return, which the last section covers. On the next period's return, line 8a asks you to verify that last period's suspended vehicles stayed within the limit.

Category W means no tax today, but you owe the tax the moment the vehicle passes the mileage limit.

Step 5. Sign the consent to disclosure and the return

Schedule 1 ends with a consent form. By signing it, you let the IRS share your VIN and proof of payment with other agencies, and you sign Form 2290 itself under penalties of perjury.

What the consent allows

Read the consent before you sign it. It authorizes the IRS to disclose information about your HVUT payment for the period to the federal Department of Transportation, U.S. Customs and Border Protection and state DMVs. The information shared is limited to your VIN and verification that you paid.

The consent also allows the American Association of Motor Vehicle Administrators, a nonprofit, to act as an intermediary that passes the data to state DMVs. Note two conditions. The agency receiving the data is not bound by the confidentiality laws that bind the IRS. And the consent must reach the IRS within 120 days of the date you sign it.

To complete it, sign, date and enter your EIN. If someone other than the taxpayer signs, such as a corporate officer, that person certifies authority to sign. If you e-file, your provider's screens collect your authorization as part of the return, so read what you are asked to agree to.

Sign Form 2290

The return carries a declaration, made under penalties of perjury, that the return and its schedules are true, correct and complete. Sign and date it and add a phone number. If a paid preparer completes it, the preparer fills in the Paid Preparer block with a PTIN.

You can also name a third party designee on the return. That person can discuss the return with the IRS. Choose someone you trust, and enter their name, phone number and a five-digit PIN.

Step 6. File and pay Form 2290 with Schedule 1

Send Schedule 1 to the IRS together with Form 2290, either electronically through an IRS e-file provider or on paper by mail. You must pay the tax in full when you file. E-file is the faster route, and the IRS requires it for 25 or more vehicles.

E-file for a stamped copy within minutes

When you e-file through an IRS-authorized provider, the IRS says your stamped Schedule 1 can be available within minutes of acceptance. The IRS encourages e-filing even for a single truck, because it usually processes faster and you avoid mailing delays.

TruckTaxPro follows three steps: enter your business details and EIN, add your VINs, then pay and receive your Schedule 1. HVUT is calculated as you enter each VIN, the system checks the return for obvious errors before it goes to the IRS, and filers typically hear back within fifteen to twenty minutes. If the IRS rejects a return, you can correct the errors and resubmit at no additional cost. Filing is available 24/7, and pricing is tiered by fleet size, from a single vehicle up to 500 vehicles.

Paper filing and where to mail it

On paper, you mail Form 2290 with both copies of Schedule 1. The address depends on how you pay.

Private delivery services cannot deliver to a P.O. box, so use the U.S. Postal Service for the Louisville address. If you do use a designated service, the IRS directs you to the Ogden Processing Center street address listed at IRS.gov/PDSstreetAddresses.

Payment methods

You can pay by any of four methods, and the tax is due in full with the return.

Pay in full when you file, because the tax is due with the return and not later.

Step 7. Check, save and use your stamped Schedule 1

Once the IRS accepts your return, you receive a stamped Schedule 1. Check it right away, save it in more than one place, and use it for registration and border entry. A problem you catch now costs far less than one a DMV catches later.

Review the stamped copy

Compare the stamped Schedule 1 to your records on four points. Confirm that each VIN matches the registration exactly, that the category and month of first use are right, that the EIN and business name match, and that the vehicle count equals what you reported. If you find a VIN error, fix it with a correction filing, which the last section explains. For other questions, call the IRS Form 2290 call site at 866-699-4096, open Monday to Friday, 8:00 a.m. to 6:00 p.m. Eastern.

Use it for registration and border entry

Hand the stamped copy to your state DMV when you register or renew a vehicle subject to the tax. For a Canadian or Mexican vehicle entering the United States, carry the stamped copy so you can show U.S. Customs and Border Protection that the tax is paid. Keep a copy of the return and every Schedule 1 in your records, and keep each period's paperwork separate.

The stamped Schedule 1 is the document your DMV and border officers ask for, so store it where you can reach it.

Replace a lost copy

If you e-filed, ask your e-file provider for the original electronic copy, which carries the IRS watermark. TruckTaxPro keeps a filing history showing each filing, tax year and Schedule 1 in one place. For a paper filing from a prior period, send a written request to Internal Revenue Service, 7940 Kentucky Drive, Florence, KY 41042-2915.

Fixing mistakes after you file

Most Schedule 1 problems fall into three groups: a rejected return, a wrong VIN, or a vehicle whose weight or mileage changed. Each has its own fix, and none requires you to start over.

Rejected returns

If the IRS rejects your e-filed return, read the message, correct the flagged field and resubmit. Typical causes include a mistyped EIN, a VIN with the wrong number of characters, or counts that do not agree between Schedule 1 and the tax computation. With TruckTaxPro, you resubmit a corrected return at no additional cost.

VIN corrections

Use a VIN correction when a previously filed Schedule 1 shows the wrong VIN. Check the VIN Correction box on Form 2290, list the corrected VINs on Schedule 1, and attach a statement explaining the correction. Use the Form 2290 for the tax period you are correcting. Do not check this box for any other reason. A VIN correction owes no additional tax. TruckTaxPro offers unlimited free VIN corrections for any paid 2290 return filed on its platform.

Weight increases and mileage overruns

Two situations call for an amended return. In both cases, check the Amended Return box on Form 2290 and write the month the change occurred next to it.

For a weight increase, use the IRS worksheet and the partial-period tables, and attach a copy for each vehicle. File late and penalties and interest apply. TruckTaxPro cites a 4.5% monthly penalty on the additional tax owed. If you have reasonable cause for filing or paying late, send the IRS a letter explaining it, or follow the steps at IRS.gov/PenaltyRelief. Do not attach an explanation to your return.

An amended return handles a change in weight or mileage, and a VIN correction handles a typo. Do not mix them up.

What to do next

Schedule 1 is simple once you see how its parts connect. Work out the category for each truck, enter the month of first use, copy your header exactly from Form 2290, list each 17-character VIN with its letter, and make the counts in Part I match the tax computation. Then sign, file by the last day of the month after first use, pay in full, and keep the stamped copy where you can find it. If something changes later, an amendment or a VIN correction fixes it without starting over.

If you want the math, VIN checks and Schedule 1 handled in one guided flow, you can e-file your Form 2290 with TruckTaxPro and have your stamped Schedule 1 back in minutes.
