I just double checked with them and it turns out they... Read more

Following up on conversation from the Fika today, Kim said the IRS is supposed to be issuing rules for tax-based (even for orgs that don't pay tax) credits by the end of first quarter.  Sounds like we all just need to be on the look out still.

Hey all,

I got plugged into this group about two weeks before GreenBuild and wasn't able to make it to the summit. I'm still catching up on all the work this group has been doing recently, but I know one of the big ticket items is the SCL Contractor Commitment.
