Prorated HVUT Form 2290: How to Calculate Your Tax When You Buy a Truck Mid-Year
When you purchase or first use a heavy vehicle after July 1, you do not owe a full year of Heavy Vehicle Use Tax. The IRS prorates HVUT based on the month you first drove the truck on a public highway. This guide explains the proration formula, shows the exact calculation for every month, and explains your filing deadline.
Quick Answer
Prorated HVUT = Annual Tax × (Months Remaining in Tax Year ÷ 12). The HVUT tax year runs July 1 to June 30. A truck first used in October owes 9/12 of the annual tax (October through June = 9 months). Filing deadline is the last day of the month following the first-used month. Select the correct first-used month when filing Form 2290 — overstating it means overpaying.

How HVUT Proration Works
Under 26 U.S.C. § 4481(c)(1), the Heavy Vehicle Use Tax is assessed for the full tax period (July 1–June 30) on vehicles first used in July. For vehicles first used in any subsequent month, the IRS reduces the tax proportionally — one-twelfth (1/12) of the annual rate for each month remaining in the tax year, including the first-used month itself.
The Proration Formula
Where Months Remaining = 13 minus the calendar month number of the first-used month (July = 1, August = 2, ..., June = 12). So October (month 4 in tax year counting from July) = 13 − 4 = 9 months remaining.
The IRS requires you to select the correct first-used month when completing Form 2290. Consulics automatically calculates the prorated tax amount when you select your first-used month — no manual math required.
Month-by-Month Prorated HVUT Table
The table below shows the prorated tax for Category V vehicles (the most common Class 8 tractor-trailer weight class, annual tax $550) and Category A (minimum taxable, $100). For other categories, apply the same fraction to the annual rate.

Under Treasury Regulation 26 CFR § 41.6001-2, state DMVs may grant temporary registration for up to 60 days when a vehicle was purchased within 60 days of the registration application date — even without a stamped Schedule 1 in hand.
This rule helps truckers who need to register a new purchase immediately. You present the dealer bill of sale or title transfer as proof of the recent purchase, and the DMV issues a temporary credential. However, you must still file Form 2290 and obtain your watermarked Schedule 1 by your actual filing deadline — the 60-day rule is a DMV accommodation, not an IRS extension.
Practical tip: File your prorated Form 2290 the same week you take delivery of the truck. Consulics returns a watermarked Schedule 1 within minutes — long before the 60-day window closes.

Frequently Asked Questions
What does "first used month" mean for Form 2290?
The first used month is the calendar month during the current July 1–June 30 tax year when the vehicle was first operated on a public highway in the United States. It is not the purchase date, title transfer date, or registration date — it is the actual date the truck moved on a public road under its own power.
If I buy a truck in November, how much HVUT do I pay?
You pay 8 months worth of prorated HVUT (November through June = 8 months remaining). For a Category V vehicle (550,000 lbs and over), the annual tax is $550. Your prorated tax would be $550 × (8/12) = $366.67, rounded to $367. Your filing deadline is December 31 (last day of the month after November).
Do I still have to file Form 2290 if the prorated tax is very small?
Yes. If your vehicle has a taxable gross weight of 55,000 lbs or more and operates on public highways, you must file Form 2290 regardless of how small the prorated tax amount is — even if you first use the truck in June and owe only 1/12 of the annual tax. The watermarked Schedule 1 is required for DMV registration regardless of the tax amount.
What is the filing deadline for a prorated Form 2290?
The deadline is the last day of the month following the vehicle's first used month. For example: truck first used in October → deadline is November 30. Truck first used in March → deadline is April 30. The annual July filing deadline (August 31) applies only to vehicles first used in July.
Can I get a refund if I sold or destroyed my truck before the tax year ends?
Yes. If you sell, destroy, or have your truck stolen (and not recovered) before the tax year ends, you can claim a prorated credit on your next Form 2290 (Part II, Line 5) or file Form 8849 Schedule 6 for a cash refund. The credit covers the remaining months you already paid for but the truck did not operate.
