When preparing an Individual (Form 1040) return with California for e-file, you may encounter the following diagnostic:
"e-File : For California E-File Purpose. CA State Wages on Form W-2 must add up to total California Wages reported on the CA Tax Return." (ref. 5218)
Please check the entries in (Wages, Salaries, Tips - Code 3 and 13). It is not recommended to use the State Wages, if different for CA returns intended for e-file. Instead, allocate CA Wages to the main form by using the primary wages input.
Make sure in the Electronic Filing (W-2 State/Local) section, (15) St has the state abbreviation and (15) Employer's State ID Number is entered.
