Why do i owe state taxes?

[Longrider6]

A number of common events:

1. You are a resident of state that has an Income Tax and you have taxable income earned in that state.

2. You have taxable property in a state that taxes out of state owners

3. You earned income in another state or tax entity like a city,  that taxes income paid to non-resident's like New York.

if you earned income in a state with income taxes, your tax liability exceeded any withholdings you had and/or estimated tax payments you made

if you tell us what state, we can provide more info.
