While most states start with your federal Adjusted Gross Income (AGI) to determine your taxable income, your new state may handle other tax-related areas, such as itemized deductions, differently. Consider the following questions when figuring taxes for your new state:
How does your new state handle itemized deductions?
While most states handle itemized deductions like a federal return, some states allow only a fixed amount of deductions, no matter how many deductions you have on your federal return.
Does your state allow you to deduct state taxes?
Most states won't allow you to deduct state income taxes you paid, but some states go the opposite route and actually allow you to deduct a portion of the federal income tax you paid.
Has your state incorporated the latest federal tax changes?
Even though most states use the Internal Revenue Code (IRC) as the starting point to determine state taxable income, many states have been slow to incorporate the latest federal changes, or have handpicked the portions of the IRC they want to use.
