A tax return that includes Form 8936 for the Clean Vehicle Credit may be rejected with F8936-030:
Reject Code: SA-F8936-030
The 'VIN' on Schedule A (Form 8936) does not match the e-File database. Please resubmit the return with the correct VIN. If the VIN entered is correct, a binary attachment or a [GeneralDependencySmall] with a description starting with "Substantiate VIN" must be included in the return.
There are two possible reasons for this rejection:
Incorrect VIN entered – Verify the VIN entered on the form with the VIN listed on Form 15400, which the taxpayer received. If the VIN entered is correct, attach a PDF copy of Form 15400 to Form 8936.
Return filed before the seller notified the IRS – The clean vehicle dealer may have delayed sending Form 15400 to the IRS, meaning the IRS was unaware of the vehicle when the return was filed.
If this reject persists when e-filing, you will need to paper file the return.
