MD passed a law whereby the entity can pay a state tax on resident members and take a Federal tax deduction, thereby bypassing the SALT limitation.  The IRS approved this method for MD.

ProSeries did their final form MD 510 update today (printing yes, Efile no). Efile will happen Feb 5th.  I see an error that Form 510 Line 20 is refunding entire tax payment when there is no refund allowed.  It just passes through to the K-1 owners. Am I incorrect or if correct, how do I tell ProSeries of their error?  I cannot get through to anyone on the phone.
