I work from my house in TX and do remote design work for a company that is located in CA. I am a contract worker for them and they are my only client and my only source of income over the year. I get a 1099 from them. All of my work is actually done physically in the state of TX with the exception of a day and a half (12 hours) of work where I worked in the office in CA.
Do I need to pay CA state income taxes for all of the money I made that year or just for the day and a half I worked on site?
