'ReturnTypeCd' (specified in the Return Header) and the return version (specified by the 'returnVersion' attribute of the 'Return' element) of the return must match the return type and the version supported by the Modernized e-File system.
IRS does not support the e-filing of Form 990 series older than 2 years.
Currently, the IRS supports the e-filing of the current year and two previous years of 990 returns. Returns for tax years older than 2 years can only be paper-filed.
If you have electronically-filed Form 990 series with ExpressTaxExempt and your return is rejected due to R0000-004-01, you may have chosen the incorrect tax period. Please contact our support at firstname.lastname@example.org for further assistance.
