> PS. States like Texas and Florida seem to get by fine without a state income tax. An income tax is just one of dozens of taxes that states collect. Here is Texas: https://bivisual.cpa.texas.gov/CPA/opendocnotoolbar.htm?document=documents%5CTR_Master_UI.qvw https://bivisual.cpa.texas.gov/CPA/opendocnotoolbar.htm?docu... Note that this doesn't include property taxes, since the state doesn't collect them (they are local taxes). > But I’ve always wondered why states that favor income taxes feel the need to have their own separate (and complicated) income tax system. Why don’t they tell taxpayers “send us a copy of your federal forms and then pay us X% of what you paid the IRS”? Are there any states that do that? The state doesn't need you to send them a copy of your federal forms, they get that data directly from the IRS when you file your federal taxes. I've never heard of any state (that collects an income tax) that doesn't start with your federal adjusted gross income, and then determine your tax by applying the various deductions that the state has determined are worthwhile. Does this person even know anything about taxation?
