IRS Error Code:
Return must not be a duplicate of a previously accepted return.
What does it mean:
Two vehicles can't have the same Vehicle Identification Number (VIN), weight category, and first used month. The IRS will consider your Form 2290 return as a duplicate filing and reject your return if you file with the same EIN. VIN, weight Category, and the First Used Month for more than once during the same tax year.
You cannot file more than one Form 2290 return for a single-vehicle. Make sure you have entered the correct EIN, VIN, weight category, and first used month. Also, check whether you have selected the right tax year for filing your return. Please contact us if you need any help.
