I am looking for a step by step checklist of things that need to be done after electing S corp status for a LLC. The LLC was created just a few weeks before the S corp election. I'm confused on a number of points. The IRS hasn't "approved" (not sure if that's the right terminology) the S corp election and I understand it will take quite some time for them to do so as they're backed up, but I understand that taxes can be filed as a S corp retroactive to the official start date of the LLC.

Should I already make estimated tax payments for the LLC's EIN number? Will I need a new EIN once the S corp election officially goes through?

Alternatively, if someone can recommend a quality CPA who charges reasonable rates, that would be helpful. I'm not really partial to taking the DIY approach.
