Thanks @MaryK4 - my wife performed her work only physically in CA (for the WI based company). however, i'm a little confused... in WI's 1NPR tax document, they say that "Nonresidents - Wisconsin taxes only your income from Wisconsin sources"; does that mean that the wages (from the WI company) is not deemed as income from a WI source solely because of this 'physical presence' test? cheers,
