E-file Rejection Code R0000-900 on Business returns
An e-filed business return is rejected with this error message:
Rejection Code R0000-900: The return type indicated in the return header must match the return type established with the IRS for the EIN
This rejection error will occur if the business entity associated with the EIN does not match the type of return being filed.
For example, if the EIN application for your business stated that it's an S Corporation but you're filing the tax return as a Partnership return, your return will be rejected with this error.
To resolve this rejection, start by verifying that you entered the correct EIN in TurboTax Business.
If you did, you'll need to create and file a new business return using the correct entity. From the File menu in TurboTax Business, choose New. You cannot transfer the information over from the incorrect return.
