Is AGI the Same for Federal and State?

While filling out your taxes, you may come across a box that requests you to fill out your “State Adjusted Gross Income.” Is this the same thing as your federal adjusted gross income? The answer isn’t as easy as yes or no since it depends on the state in which you live. The two amounts can differ quite a bit, especially since some states don’t follow the federal tax code. Some states don’t even require residents to file state taxes. 

In states that do require you to file an annual income tax return, your federal AGI is used as a starting point to calculate your state taxable income. Many states choose not to follow federal deductions that save you money. If you are unfamiliar with your state’s tax code, you can find it through the revenue office or you can request the help of a tax professional in your state.
