States react differently to changes to federal tax law. For example, some states automatically conform to federal tax law as soon as legislation is passed. Other states require their legislatures to adopt federal tax law as of a fixed date. This generally occurs on an annual basis. There are some states, however, that pick and choose which federal provisions to adopt.
Because of this, your state income tax rules may be drastically different than the federal income tax rules. For example, you may be better off claiming the standard deduction for federal tax purposes but itemizing for state income tax purposes. We have monitored your state’s response to the TCJA and will help you minimize your state income tax bill.
