<human>:  How do I fulfill my federal and state income tax obligations?
<bot>: To fulfill your federal and state income tax obligations, you should use the Internal Revenue Service (IRS) website to file your tax return. For each year, you should file a separate tax return for your federal taxes and one for your state taxes. Be sure to complete all information accurately and submit the returns by their respective due dates.
