1065 created pre Covid never filed return

• A domestic partnership must file an information return, unless it neither receives gross income nor pays or incurs any amount treated as a deduction or credit for federal income tax purposes.

I don't know how the partnership can be "closed with 0 income and 0 expense."  Even if the partners had resolved to close/dissolve the partnership in its initial year, Form 1065 still should have been filed for the initial/final year - and the late filing penalty would still have been applicable for the year.

That said, check if the IRS First-Time Penalty Abatement administrative waiver is still in force.

The related provisions used to be prescribed in IRM 20.1.1.3.3. and IRM 20.1.1.3.3.6. 

I haven't handled a similar issue lately and my info may not be up-to-date.  

California R&TC Section 19132.5 also allows for a First-Time Penalty Abatement, in case it's a CA partnership.

Hope this helps.

New clients, new pita problems. One of the reasons I don't want new clients and rarely accept them, I have plenty of work with the clients I have now (some are pita, most are good).

Were these expenses Organization costs and Start up costs only?

And the business never really started?

If yes, maybe they do meet the not having to file criteria.

And yes, they can dissolve it any time they want.

Is it really a Partnership? Or an LLC?
