Just ran into an interesting situation with ComEd in Colorado Springs. Three of the 48 months show estimated reads with no true-up. Sales tax is being charged even though the client has a valid exemption certificate on file.

How do you organize client files?
Solid analysis. One thing I''d add is to verify the seasonal rates apply May-October against the original service application.
Excellent discussion everyone. Marcus F, your approach on this Alliant Energy case is solid. For newer members, this is a great example of why thorough tariff review is essential.
