Fee to complete 990?
How much do you charge to complete the 990 for a client? What about the Char500?
I only do 990's for my Pro Bono NP's. For client NP's, i have their CPA do it. That way, the CPA can review my file regularly, and i don't have to deal with the 990's.
If you want to do them, you could charge hourly, or figure out how long it takes you to complete, then come up with a flat fee that is appropriate for each client.
