Maryland Form 510 Line D-1-Attachment Not Received

[LRJCPA]

In regards to filing MD Form 505-Nonresident Income Tax Return, I have been experiencing an issue with Line 45-Nonresident Tax Paid by Pass-Through's.  MD partnerships that withhold nonresident tax from partners distributions are reported on Form 510, Line D-1. Non Resident Tax paid by PTE.  For the past two years, I have been having issues submitting MD Form 510 with my MD-505 through ProSeries software.   I attached the form in the EF center and specifically select type Form "510 K-1" as the attachment.  The returns are received by Maryland but MD disallows the tax withheld claiming they did not receive the attachment. This form is required for all Nonresidents. I then have to respond to the MD notice and resubmit all the K-1's by fax.  Has anyone else has this issue?  Thank you for your help.

As a MD CPA I get the notice on maybe 25% of the returns even though the K-1 was attached.  I actually get this on many states.  My guess is that K-1 withholding is not tracked by the states like W-2 or 1099 withholding is, so they cannot see it in their system (they don't post the withholding from the 1065/1120S to the individual).  It's embarrassing because the client thinks we messed up but after explanation and mail in, all is well.

Thank you for the information. MD did receive the K-1 attachments before 2017.  A change must have occurred in 2018. I am working with Intuit to see what exactly occurred.
