Getting a notice of rejection after submitting your Heavy Vehicle Use Tax (HVUT) return can be a significant roadblock, especially if you require that stamped Schedule 1 to get on the road. Among the most frequent roadblocks truckers face is the EIN mismatch error.
If the IRS system is unable to match your Employer Identification Number with your legal business name, your return will automatically be rejected. The first step to being IRS compliant is to understand why this occurs and how it can be corrected.
The IRS has a complex matching system to ensure that the entity responsible for paying the tax is the same as the one recorded in their master file. A rejection is normally due to one of the following:
The IRS assigns a four-character Name Control to each EIN based on the first four letters of your legal business name. If you have a Doing Business As (DBA) name or a nickname other than your legal business name on your EIN confirmation letter (CP 575), it will generate a mismatch.
If you have recently acquired a new EIN, you may experience a delay. It usually takes the IRS 15 business days to match the new number on their e-file systems. Filing before the window closes may cause an "Invalid EIN" or "Mismatch" error.
The IRS database is extremely accurate. Including or excluding an ampersand (&), a hyphen, or suffixes such as "LLC," "Inc," or "Corp" can result in a failure if it doesn't match your taxpayer identification records exactly.
Don't worry if the IRS rejects your return. Most IRS-approved e-file providers will let you fix it for free.
An EIN discrepancy is more than just a nuisance—it can result in IRS fines and interest accruals if the deadline expires before you manage to successfully file. Additionally, without a verified return, the Department of Motor Vehicles (DMV) will not permit you to renew your vehicle registration.
To avoid any future problems, it is always a good idea to keep a copy of your tax documents and use an e-file service that performs real-time error checking before you submit your return.
Pro Tip: If you are a Sole Proprietor, make sure you are entering your EIN and not your Social Security Number (SSN). The IRS requires an EIN for all Form 2290 submissions.
