It's not unusual for ODT to take 2 years to catch you for not filing a SDIT return. There's another, but unlikely, possibility: your employer mistakenly withheld SDIT for a district you did not live in and you may be entitled to a refund. To verify that you live(d) in a school district (or city) with an income tax enter your address at:
