The tax year 2018 Delaware Software Provider Letter of Intent is currently available. For tax year 2018, Delaware is using the FTA State Exchange System to distribute the LOI, XML schemas, test packets and other files.
For software vendors that worked with Delaware in 2017, please contact REV_MeF_Support@delaware.gov to request access to the 2018 Delaware Software Provider Letter of Intent. In your request, you should include the email address of the SES authorized user who plans to access the LOI.
Currently, Delaware is planning to release our XML schemas and test packets in late October.
Delaware is expecting to begin acceptance testing for all tax types on or before 11/26/2018. Tax year 2018 production will begin in conjunction with the IRS tax year 2018 startup date.
