Where Taxable Gross Weight shows up

Taxable gross weight appears on Form 2290 as the key input that determines the applicable HVUT rate and weight category bracket. It is sourced from vehicle registration documents, cab cards, and equipment specifications — not estimated from memory. Adding a heavy trailer changes the calculation. An incorrect weight category can mean filing in the wrong tax bracket, so supporting records should be kept with the Form 2290 file.
