How to File a Form 2290 Gross Weight Amendment

Sign in to Simple2290 and begin a new filing.

Select Amendment – Taxable Gross Weight Increase as the form type. Then choose the business connected with the original return.

Enter the correct:

• Tax year
• First-used month
• Amendment month

The amendment month is the month when the vehicle moved into the higher weight category. It is not necessarily the month when you discovered the change or started preparing the amendment.

Select Final Return or Address Change only if either option applies to your business. Otherwise, leave them unselected and continue to the vehicle section.

Click Add Amendment Vehicle to open the vehicle form.

Start by entering the VIN exactly as it appeared on the original Form 2290. Check every character carefully before continuing.

Next, select the vehicle's previous weight category. This must match the category reported on the earlier return.

Then choose the new weight category. The new category must be higher than the old one. If both categories are the same, there is no gross-weight increase to report through this amendment.

Finally, choose Yes or No for logging use. Use the same logging status that correctly applies to the vehicle.

Review the details and click Save.

The vehicle will now appear in the amendment list with its:

• VIN
• Previous weight category
• New weight category
• Logging status
• Additional tax due

Simple2290 calculates the additional tax using the old category, new category, amendment month, and logging status.

The IRS calculates this tax for the remaining part of the tax period. In simple terms, the old partial-period tax is subtracted from the new partial-period tax, and you pay the difference. The amended Form 2290 is generally due by the last day of the month following the month in which the weight increased.

If the amount doesn't look right, check the first-used month, amendment month, previous category, and new category before moving forward.

Add any other vehicles that had a qualifying weight increase during the same amendment month. When the list is complete, continue to the IRS payment step.

Select how you want to pay the additional HVUT to the IRS.

Simple2290 shows three payment options:

Select one payment method and continue to the review page.

The review page brings the full amendment together. Don't rush through it. Open each section and confirm the information before paying the filing fee.

Check the following:

• Business name and EIN
• Form type and tax period
• First-used month
• Amendment month
• VIN
• Previous weight category
• New weight category
• Logging status
• Selected IRS payment method
• Total additional tax due

Use the Edit icon if anything needs to be changed.

Make sure the previous weight category matches the original return. The new category should reflect the vehicle's updated taxable gross weight, including the truck, the trailer normally used with it, and the heaviest load normally carried.

Once everything is correct, click Continue to Payment.

The next page shows the Simple2290 service fee for preparing and transmitting the amendment.

For the filing shown in this process, the service fee is $9.95.

This fee is separate from the additional HVUT owed to the IRS. Paying the Simple2290 fee does not automatically pay the IRS tax when you select EFTPS or a credit/debit card.

Enter the requested card information, including:

• Card number
• Expiration date
• Security code
• Name on the card
• Billing details, when requested

Review the amount, accept the Terms and Conditions, and complete the service-fee payment.

On the Submission Confirmation page, give the filing one final check.

Read the authorization statement, confirm that the information is correct, and enter the signing name or PIN requested by the system.

When you're ready, click Submit Filing.

Avoid refreshing the browser or clicking the submission button more than once while the return is being transmitted.

After submission, Simple2290 may show a payment reminder.

If you selected EFTPS or credit/debit card, follow the provided IRS payment link and pay the additional tax separately. Your amendment submission and IRS tax payment are two different actions.

If you selected Electronic Funds Withdrawal, confirm that the bank information and withdrawal details are correct.

The IRS requires the additional tax to be paid in full with the amended return.

Return to the dashboard after submitting the amendment.

The filing may first show a pending or transmitted status while the IRS processes it. Once accepted, the status will update and the available filing documents can be downloaded.

Keep copies of:

• The amended Form 2290
• The updated Schedule 1, when provided
• The IRS acceptance record
• The IRS tax-payment confirmation
• The Simple2290 payment receipt
