I'd wait and see, but it's not looking good.

The latest I heard (yesterday) is that it's unlikely that VA changes will be retroactive as they have been in the past.  For VA laws to be retroactive they have to contain an "emergency" clause which requires an 80% yea vote in the VA legislature.  There are several current bills floating around, but as of yesterday they had all been stripped of their emergency clauses (since none of them were able to get 80% to agree).  Bills passed without an emergency clause cannot take effect any earlier than 7/1/19.  So my guess at this point, the VA fixed date conformity will be stuck at pre-TCJA rules for at least 2018, probably 2019 (unless they want to try to make everyone file "before" and "after" tax returns for 2019).

On top of that, there was a scandal last week involving the current Governor and there's talk of him stepping down.  He's been fairly vocal on what he's not willing to sign in terms of tax reform.  No idea what the Lt. Governor's views are at this point when it comes to tax conformity, but things seem to be falling along party lines and I doubt that will change.

So, that's where we are at the moment.
