Withholding for multiple states (NY and CT)
I read a bit and understand I won't be double taxed (resident of NY, working in CT). However, what isn't clear after reading is if I actually need to have withholding for both states throughout the year? e.g. Do I actually pay the taxes for both states, only to get a full refund from NY for my CT wages? I don't understand why I should be required to have NY collect regular taxes from me (and hold on to my cash for a year) only to give it back to me on April 15 the following year. What am I missing? Let's assume the dividend / interest question is moot (I will pay estimated taxes on that in NY) and we are only talking state taxes on my wages.
Thanks!
