Wife = Self Employed; Me = W2...Estimated Taxes
My wife started a business under a unique LLC and EIN. I work for a large employer. As we file taxes as "married, filing jointly" and the Schedule C rolls up into out joint tax return, can I just increase the withholding my employer takes from my bi-weekly check (to cover LLC taxes) instead of wife paying quarterly estimated income taxes? If so, do I still need to make quarterly self-employment tax payments for that portion of the tax bill (Medicare/SS), or can these just be reconciled annually? Thank you.
