Form 2290 for Mack Anthem & Pinnacle: Taxable Gross Weight & Filing Guide

The Mack Anthem and the classic Mack Pinnacle represent the gold standard of rugged American trucking engineering. Powered by the proprietary Mack MP7 or MP8 engine with the mDRIVE automated manual transmission, Mack tractors are designed for durability across long-haul highway routes, heavy regional distribution, and severe-duty vocational transport.

Under 26 U.S. Code § 4481, any commercial motor vehicle with a taxable gross weight of 55,000 pounds or more operating on public highways must file Form 2290 and maintain a stamped Schedule 1.

Why Does a Mack Anthem or Pinnacle Require Form 2290?

An unladen Mack Anthem day cab weighs roughly 16,400 pounds, while a 70-inch stand-up sleeper model weighs approximately 18,600 to 19,500 pounds. While the tractor alone is below the 55,000-pound line, IRS regulations mandate that taxable gross weight be calculated based on the combined configuration.

Because a Mack Anthem or Pinnacle customarily tows loaded commercial trailers (53-foot dry vans, refrigerated reefers, flatbeds, or bulk dump trailers), the total combined operating weight reaches the standard federal interstate limit of 80,000 pounds.

• Mack Anthem 70-inch Sleeper: Standard long-haul line-haul at 80,000 lbs (IRS Category V).
• Mack Pinnacle Day Cab / Sleeper: Heavy regional freight and tanker transport at 80,000 lbs (IRS Category V).
• Mack Granite Vocational Series: Heavy dump, mixer, or refuse truck operating between 65,000 and 80,000 lbs (IRS Categories Q through V).

How Much Is the Form 2290 Tax for a Mack Truck?

For commercial motor vehicles operating at 75,000 pounds and above, Form 2290 sets the annual tax rate at $550 for a full 12-month period (July 1 to June 30). For qualified logging vehicles, the rate is discounted to $412.50.

If you put your Mack truck into service mid-cycle, the tax is prorated from the First Used Month (FUM). For example, a Mack Anthem first operated in October owes $412.50 for the remaining 9 months of the tax year.

What Is Needed to e-File Form 2290 for a Mack Truck?

Gather the following five essential credentials before starting your online filing:

• Active Federal EIN: Must be registered under your business entity name with the IRS for at least 10 business days.
• Mack 17-Character VIN: Starting with 1M1 or 1M2, found on your title, cab card, or driver door post.
• Taxable Gross Weight: Category V (75,000+ lbs) for standard 80,000 lb highway configurations.
• First Used Month (FUM): The calendar month the truck was first driven on public highways during the current tax period.
• Payment Preference: Direct debit (EFW), EFTPS, debit/credit card, or check voucher.

What If Your Mack Operates 5,000 Miles or Fewer Annually?

If your Mack truck is used primarily as a yard tractor, secondary backup vehicle, or severe-duty equipment mover that travels 5,000 miles or fewer on public highways during the tax period (7,500 miles for agricultural vehicles), it qualifies for Category W (Suspended Vehicle).

Filing Form 2290 is still mandatory to notify the IRS of your suspended status. The IRS issues a stamped Schedule 1 marked "Tax Suspended" with $0.00 tax due, allowing you to renew state registration without paying the $550 tax.
