It is july 2022 and I am closing an LLC and a Corporation. Can I to do my federal and CA taxes for 2022 now or do I have to wait until early 2023 to do them?

If I havwe to wait till 2023, then it seems I have to keep the entities open with their bank accounts open until then.  I would rather close up everything now.  What gotcha's mght happen if I close everything now?
