Dual state taxation

Hello, 

 

Pl. clarify the following. I am using some numbers to illustrate the problem, not that they are real numbers, nor need to apply any tax brackets etc. But I want to understand the generic priniciple. Pl. consider this scenario.

 

- I live and file taxes in Arizona. And state tax % is approxmately is, say 5%. Most of my income is Arizona income, say it is 300K

- However I have an additional income from California also, and the income say $200,000. CA tax % is say 10%

So total income is 500K. With this situation,  when I need to pay taxes ...

- Do I end up paying 5% of the CA income of 200K  besides 5% of AZ income of 300K to AZ?

- And also another10% of the CA income 200K to CA as well?

 

OR

- Will I be paying only 5% of AZ income of 300K to AZ

- And 10% CA income of 200K to CA

 

Pl. help understand how this works.

 

regards
